This article reports findings from a one-month design research project in which four textile and fashion designers engaged in collaborative exploration of technical and artistic knowledge inherent in folds and folding. They experimented with textile technologies and construction methods to design, fabricate and analyze three-dimensional dynamic materiality in electronic textiles (e-textiles). The focus was on sensor structures achieved by knitting, weaving, pleating and coating techniques. The analysis of measurements of electrical resistance between one and 36 sensing areas per sample demonstrate the added value of folds integrated into textile sensor structures. The authors discuss types of folding and their aesthetic, textural and sensorial advantages. Detailed information on design, fabrication and experimental results is provided in supplementary materials to the article.
Language is the essential medium of human communication, and it takes various
forms, from music to computer code, each of which is suited to specific purposes.
This paper explores the realm of vernacular language, infused with sarcasm, within
the contexts of poetry and folk music. Specifically, we explore its transformative role
within the socio-political landscape of post-1967 Egypt, shedding light on its
dynamic impact on the political and social structure of the time.
Our research places particular emphasis on the works of Ahmad Fouad Negm and
his collaborative partnership with Sheikh Imam. Through their unique lens, this
paper explores the profound significance of vernacular poetry as a powerful tool for
articulating the everyday struggles and sentiments of the underprivileged class.
Their compositions served as a means of resistance to Egypt's ruling class and
provided a powerful voice for those marginalized within society. This study
highlights the enduring importance of vernacular sarcastic poetry in addressing
socio-political issues and advocating for the underprivileged in post-1967 Egypt's
socio-political landscape.
On Figures and Pointclouds: An exploration of 3D scanning through process-driven creative research
(2022)
This article traces creative research on 3D scanning, that we – Maria Kyrou in collaboration with Jiawen Wang (Student Assistant, study program Art & Media) – developed in the context of the InKüLe Project (UdK Berlin) during the winter semester 2022-23. Following an associative and process-oriented approach, we pursued a creative exploration of 3D scanning, while illuminating both conceptual and technical aspects. This case study had a double scope: to experiment with the possibilities of different 3D scanning workflows for the creation of hybrid artistic formats and to reflect on ways of relating to emerging digital media, in order to facilitate their critical integration into a learning process for students and educators alike. 3D scanning serves thereby as a ‘Leitmotif’ for a broader inquiry on how mediators may learn.
Our project focused on the 3D capture of human figures, creating an interplay between scanning method and captured form. As an experimental exploration, the results of 3D scanning were interpreted through intuitive associations stemming from different art fields and visual media. Exploring both static and dynamic forms of 3D capture, the idea of movement became central as the creative process unfolded. Considered from the perspective of experimental media didactics, the article concludes with the definition of two pairs of qualities, which were central in its development and relation to emerging digital media.
Hybrid conferences and events are becoming the norm and even after the pandemic, a majority of students are asking for hybrid education as a permanent format at universities. In parallel, hybrid learning, which allows participants to connect on-site or digitally, means greater logistical and cognitive effort for educators, as well as active, participatory support by students. In the wake of these newly emerging learning cultures, it is vital to design them sustainably and critically reflect their impact. In this workshop, participants are invited to co-design future learning artefacts and practices. The workshop is conceived as a playful participatory design format in which the relationship between technology, pedagogy and future skills will be reflected and translated into provocative future artifacts. Whether your interest lies in emerging technologies, education, future design or sustainability, your views and expertise are welcome. This workshop is framed within the overarching question of "how hybrid learning spaces can be designed sustainably?" and within the larger context of the third-party funded project "InKüLe - Innovationen für die Künstlerische Lehre" at the UdK Berlin. The project InKüLe aims to develop and implement digital/hybrid forms of education using emerging technologies as well as interdisciplinary teaching and learning formats, as well as critically reflect their impact. The workshop results, therefore, contribute to the extensive discourse of the UdK Berlin and its university network of the Stiftung Innovation in der Hochschullehre.
Planetary Embodiment (2021-2023) is a seminar and transdisciplinary artistic practice coordinated by Luïza luz at the Berlin University of Arts as part of Studium Generale. Engaging with the "Transformation of Silence Into Language and Action" as suggested by Audre Lorde, we envisioned this publication with the intention of investigating the power of words in breaking silences and cultivating awareness of intersectional environmentalism. The content was developed through workshops and guest lectures in collaboration with Andrea Galano Toro, gal sherizly, Denilson Baniwa, participants, and friends. In reciprocity for the causes we are addressing, the profits from this publication are directed to initiatives supporting Indigenous, land, human, and more than human rights.
Im Rahmen der TURN Konferenz `23 stellte das InKüLe Team mediendidaktische Vermittlungsformen für eine nachhaltige Implementierung von immersiv-medialen Lernumgebungen an einer Kunstuniversität zur Diskussion. Hierzu wurden das technologische VR-Toolkit und das ‚sessions_vr‘ Lehrformat, welches prozess- und erfahrungsorientiert die interdisziplinäre Zusammenarbeit von Studierenden mit immersiven Medien eröffnete, vorgestellt.
‚sessions_vr‘ wurde im Sommer Semester 2023 als Workshop-Reihe mit verschiedenen thematischen Schwerpunkten angeboten. Teilnehmende erhielten Einführungen in innovative Tools und Plattformen, wie zum Beispiel die VR-Sketching-App Gravity Sketch, und hatten die Möglichkeit im Gestaltungsprozess sich transdisziplinär auszutauschen. Durch ein offenes Format zur Erkundung von VR wurden die Teilnehmenden befähigt, die vorgestellten experimentellen Formate weiterzuentwickeln oder selbst zu initiieren. Gleichzeitig erlaubte ‚sessions_vr‘ die kritische Reflexion von Lehr- und Lernkulturen durch die Befähigung von direktem Feedback und dessen Umsetzung in neuen Workshops.
Ziel ist die Schaffung einer offenen Lernumgebung, in der das spielerische Experiment und erfahrungsbasiertes Lernen im Mittelpunkt stehen, und worin kollektive und kritische Wissensproduktion gefördert werden kann. In einer zweiten Projektphase im Winter Semester 2023 sollen die Ergebnisse in Form eines mediendidaktisch reflektierten VR-Toolkits dokumentiert werden, um so den Unterricht von VR-Technologien an verschiedenen Hochschulen und in anderen Bildungskontexten unterstützen zu können. Als Teil der TURN Konferenz wurden die ersten ‚sessions_vr‘ Ergebnisse präsentiert und kritische Reflexionen durch ein größeres und transdisziplinäres Fachpublikum weiter befragt.
Separating data and design
(2023)
This paper explores the concept of "Separation of Concerns" and its relevance to artistic education. We discuss the importance of separating data and design in software development and its benefits in opening access to distinct layers. Arguing that the separation of data and design is crucial in creating functional and effective digital tools for artistic education.
In a state of ontological crisis, all boundaries between human and machine, nature and culture, and the organic and inorganic have been severely blurred. These are times of curious contrivances, novel natures, inescapable automation, and posthuman performances – where human and nonhuman find themselves being entwined, meshed and muddled into new unwitting entanglements. But from biased machine-learning to surveillance capitalism and digital colonisation – what power-structures are implicitly and covertly being embedded into these technologies?
In a demand for more transparency, multiple movements are making a turn toward democratising knowledge and technology. They are exploring the potentials of open data, software, hardware and wetware to battle concealed hierarchies and partisan paradigms – eliciting a practice of counter-coding in a proliferating politics of machines.
Within the Politics of the Machines conference series – following Copenhagen (2018) and Beirut (2019), the third POM conference took place as a hybrid conference on the 14-17 of September 2021, hosted by the chair for Open Science at the Technische Universität Berlin / Einstein Center Digital Future and the Berlin University of the Arts / Weizenbaum Institute.
The goal of this edition of POM was to debate and devise concepts and practices that seek to critically question and unravel novel modes of science – what roles do academia, researchers, scientists, artists and designers have to take on in times of crisis, how must we re/position ourselves?
What chances or challenges might the democratisation of technology and knowledge elicit, and what potential do practices such as critical making, community science, trans/feminist hacking or citizen forensics hold to bend the hierarchies of power – how can we work with active matter and technical turmoil to re/act?
‘POM Berlin – Rogue Research’ aimed to probe new methodological approaches from art, design and civic activism within the framework of academia in order to surface an inter- and transdisciplinary terrain that attempts to exceed the boundaries of theory and practice, academia and activism, and science and civil society.
The POM Berlin conference emerged as a collaboration between the Technische Universität Berlin, the Berlin University of the Arts, Aalborg University, Aalto University, and the International University of Beirut. The conference took place over four days, comprising a series of tracks, interventions and a student exhibition.
The conference brought together track chairs, speakers and interventions from 31 countries across Asia, Africa, Europe, North and South America, representing critical perspectives on technology – decolonial, feminist and sustainable approaches, across disciplines, knowledge cultures and spaces.
Taking place in times of a pandemic and geopolitical crisis, the editors, conference committee and organisational team would like to sincerely thank all of the track chairs, authors, intervening artists and designers, and students involved in this endeavour, for making both the conference and the resulting proceedings possible. It is the profound engagement of all parties, especially the ever-growing POM community,
that has allowed this publication to arise.
New method for the viole d'amour (the love viol) : its origin and history and art of playing it
(1885)
This thesis focuses on small scale residential cooling application with unitary air conditioning units as they are wide spread in the so called Middle East North African Region. The presence of these single room or single apartment cooling systems is evaluated and their impact throughout the region assessed. They have a tremendous impact on the electric supply in countries like Saudi Arabia where most of the households already have an AC-unit. The impact in other countries with relatively less installed systems, like in Egypt, is already crucial and leads to regular power cuts. However, the stability of the grids of these countries will decrease further with a higher penetration rate of electric air conditioning systems. Current technology development aims to reduce the buildings cooling energy demand, increase the coefficient of performance, or to substitute the cooling mechanism with a different approach such as sorptive cooling systems. However, these systems require a costly and time intensive change of the building structure or an exchange of the existing cooling system. Due to this reasons, this thesis focuses on the additional installation of a small scale PV electric system, including a battery and applying advanced control strategies to utilize the thermal storage capacity of the building masses. Therefore, the present room cooling system is modeled as a reference system as it could be present throughout the entire region. This system consists of a room model of a typical apartment structure and is cross validated. Two use cases are applied: a bed room and a living room. Further, it includes a model of the solar electric system which is as well parametrized to regional values. Newly, a split unit model and an extended Kinetic Battery model are set up. The single models are combined to an entire system simulation. Afterwards, the main parameters are varied in particle swarm optimization runs to determine the impact of various boundary conditions, such as the electricity price and feed in tariffs, battery and thermal storage capacities, and solar collector field size. The simulation results are compared in terms of levelized costs of cooling, solar coverage rate and the solar cooling autonomy. The findings are compared in a case study. This study highlights the results of the Hurghada, Egypt city district of El Gouna. There, personal observations of the results where possible and an in depth analysis of the results was undertaken. In this location, the levelized costs of electricity for a small scale PV system with 1kWpeak drop there to 0.18USD/kWh with a short investment period of 5 years. They even drop to 0.08 and 0.05USD/kWh when taking an investment period of 15 or 25 years into consideration. With this values, various levelized costs of cooling are simulated as a parameter field of the particle swarm optimization. The findings show, that in most cases, the cooling costs become negative, even with relatively short investment periods. Within a bed room, a solar coverage rate of 0.9 can be achieved with a small scale PV system with weighted costs of only 677USD. In terms of solar cooling autonomy, the most cost efficient system has weighted costs of1,036USD, resulting in a coverage rate of 0.71. The living room air conditioning system can achieve best weighted costs of1,459USDfor a cooling autonomy of 0.86.Further, the practical application of a small scale PV electric solar cooling system was evaluated by the author in the case study location itself. The limitations of the theoretic system design are presented and discussed. Part of this analysis is the thermal stratification in typical vaulted apartment structures as they have a huge impact on the deviation between simulated and measured room air cooling demand.
Originally, music choreography works of rhythm are closely tied to music and seek the most comprehensive possible transfer of all musical parameters into spatio-temporal as well as dynamic correspondences. Following the boundary-expanding developments in music and dance from the 1960s onwards, other intermedial forms of reference have become conceivable. Dorothea Weise breaks these down exemplarily and presents a system (to be questioned critically and thought through further).
The transmission of musical processes via corresponding movement sequences can be seen as the foundation of Dalcroze Eurhythmics. Accordingly, the sensibility for rhythm and its inherent interplay of tension and relaxation in space and time is significant for the embodied visualisation of music. For creating wider aesthetic experiences and confrontation with the rhythmical structures of music and other artistic expressions—such as visual arts and literature—it can be helpful to take a look at other concepts of rhythm. Recent theories about rhythm from the music theorists Steffen A. Schmidt and Christopher Hasty, as well as the philosophical thoughts about speech from Ludwig Wittgenstein, described as «Saying and Showing», open up additional structures that may enrich the process of artistic creation and performance in eurhythmics.
Jumping over one's own shadow and expanding boundaries are frequent demands in the field of music and movement through the special methodological possibilities of eurhythmics. This is true for the learners as well as for the teachers. With a view to the concept of perception of constructivism, it is first clarified why perceptions are always individual and bound to subjective experiences. Then the ‘Gegen-Stand’ comes into play as a surface of friction and a basis for an active and reflective engagement that is capable of producing new results.
Choreomusical work opens a world of images and signs beyond language. The expressiveness of what is heard and seen merges with the tacit-knowing-view of the viewer and the listener.
Meaningful resonances and processes of understanding develop along the structure of the work and within the individual construct of implicit and explicit knowledge of the audience. In this process, perception plays a major role. Aside from the obvious processing of acoustic and
visual stimuli, this paper will look at the role of proprioception, especially the kinaesthetic sense, with regard to its role as intermediary and creator in the process of perception.
Marianne Steffen-Wittek initially concentrates on theoretical concepts of rhythm with special reference to texts by the founder of eurhythmics Émile Jaques-Dalcroze, and corresponding writings by Henrietta Rosenstrauch. As music educators, their writings provide a deep insight into the analysis of difficulties in the realisation of rhythms and ways to overcome them. The following selection of current theoretical concepts of eurhythmics in Germany shows in particular an intensified view of the connection between perception and movement and its (still to be further researched) effects on pedagogical and artistic activity. Rhythm theory and research in rock, pop, jazz and groove-based music is a relatively young field. In her remarks on groove and swing in jazz music, Steffen-Wittek refers to Mark Russell Doffman, whose embodied concepts can be important material for jazz-oriented rhythm teaching. She develops practical examples and connects them with the complex theoretical concept of eurhythmics by Holmrike Oesterhelt-Leiser.
Understanding dance as a sensory and mentally grounded organisation of movement is at the core of Stephanie Schroedter's reflections. Of particular interest is the “muscle” or “movement” sense, which Émile Jaques-Dalcroze already insisted upon with great clairvoyance to train the transformation of sounds into spatio-temporal and dynamic nuanced, “plastic” movement creations. Against this backdrop Schroedter traces the “discovery” of our kinaesthesia back to its beginnings – as a sense responsible for the perception of one’s own movements, but also for self-perception based on movements. Subsequently, from a phenomenological perspective, the concept of a “kinaesthetic hearing” is established as an immediate interweaving of auditory perception with (visible or imaginary) movements.
While a standard definition of (musical) rhythm indicates that it consists of the duration of individual events of sound and silence, this paper suggests that rhythm consists of the units of events such as
sounds, silences and bodily movements which are no preexisting formal objects that can be combined, but units of action that are constituted in the course of rhythmic experience.
DRAFTS#3
(2022)
DRAFTS#3 invited more than 80 designers, design researchers, and design students to discuss the role of artifacts in research and design activities within disciplines such as fashion, textile, and interaction design through the means of two exhibitions and one symposium.
A cooperation between the Swedish School of Textiles – University of Borås and designtransfer – UdK Berlin.
Handy Handbook of Hands
(2022)
Handy Handbook of Hands is about the finger binary systems. The first part of this book shows how to count and display binary numbers on the fingers. In the second part, a binary finger alphabet is developed that enables the communication of words with fingers.
Children learn to count with their fingers at an early age. The Latin word for fingers or toes “digitus” is the root of the English word digit. A normal person has, if nothing unforeseen happens, five digits on each hand. This limits the counting of the fingers to ten. By using binary numbers with the fingers of one or both hands, it is possible to count and display all numbers from 0 to 1023.
Counting in binary is one thing, but fingers can switch from “counting mode” to “text mode”. The binary finger alphabet technique allows communicating words and even entire sentences with the fingers. It is similar to Morse code and gives each letter of the alphabet a specific finger constellation. It is structured from simple finger constellations for the most commonly used letters of the English alphabet to more difficult constellations for rare letters.
Ideathek
(2021)
What does the digitization and mediatization of space mean for our physical and virtual knowledge spaces. How can architectural and interface design promote innovation and creativity through their spatial configurations and protocols? Which new approaches need to be deployed so that complexity is created instead of reduced?
Abstract. This study compares performance of different speech com-
mand classification systems which can be executed on an Raspberry
Pi Zero ARMv6 architecture. Three systems are evaluated: first one,
TREELITE_MFCC, is based on Treelite system cross-compiles a MFCC-
classifying Random Forest into a highly optimized shared library; second,
TFLITE_MFCC, performs classification of MFCC inputs by means of
convolutional neural network encoded as a lightweight TensorFlow Lite
model while the third one - labeled as TFLITE_RAW - uses more com-
plex network to directly classify the audio signal. We evaluate models
not only in terms of their accuracy and precision, but also in terms of
execution time, voltage, current and energy consumed. We observe that
while TFLITE_RAW offers superior performance in terms of accuracy,
TREELITE_RAW is also worth of consideration for low-latency real-
life applications since it offers relatively good performance (avg. micro-
precision=0.917) but its predictions, when executed on Raspberry Pi
Zero, are significantly faster and cost less energy than TensorFlow Lite
models.
The original TuringTest is modified in order to take
into account the age&gender of a Judge who evaluates the
machine and the age&gender of a Human with whom the
machine is compared during evaluation. This yields a basic taxonomy of TuringTest-consistent scenarios which is
subsequently extended by taking into account the type of intelligence being evaluated. Consistently with the Theory of Multiple Intelligences, nine basic intelligence types are
proposed, and an example of a possible scenario for evaluation of emotional intelligence in early stages of development is given.
It is suggested that specific intelligence types can be
subsequently grouped into hierarchy at the top of which is seated an Artificial Intelligence labelled as “meta-modular”. Finally, it
is proposed that such a meta-modular AI should be defined as an Artificial Autonomous Agent and should be given all the rights and responsibilities according to age of human counterparts in
comparison with whom an AI under question has passed the
TuringTest

Spaces of Collectivity
(2021)
How is it to act collectively when each one of us brings our own
perspective, values, assumptions, and also our own language? How does
from the many become ‘one’? What compromises does one need to make on the
way? These were the questions we explored during the workshop Spaces of
Collectivity. The aim was to collectively experience and enjoy space,
while noticing how different our perspectives on it are, and how being
able to talk about them, is key to any collective act of visioning,
making or caring for space. Maps, as final products, and map-making, as
the process of making these, became the tools to visualise and thus be
able to better discuss these challenges.
What are recent examples of practices in which ‘assembling’ and
‘disseminating’ reconfigure agencies, resources, affects and information
to give rise to new forms of collectivities? This round table brings
together Björn Heerssen and Noel David Nicolaus from the
interdisciplinary collective Clusterduck, and sociologist Serhat
Karakayali to ask about the relationships and interdependencies between
‘assembling’ and ‘disseminating’ as constitutive mechanisms in processes
of collectivization. How do agencies, resources, affects and information
elevate processes of creating collective feelings? Together we discuss
how ‘assembling’ and ‘disseminating’ take shape in each example, leading
to different forms of collectivities; what practicable mechanisms,
interfaces and infrastructures come into play; and how do these two
instances approach possibilities of collective interaction
in terms of
‘sharing’ and ‘learning’.
What practices constitute the commons? What are the conditions of the
situated processes of commoning? What and how do we thereby learn? What
would constitute a new sense of sharing, distributing, partaking? And,
how can we take the idea of relationality seriously and institute
structures of reciprocity between art, academia, and activism? To address
these questions the round table commoning/communing brings together three
projects focusing on urban practices of commoning.
The round table instituting/fleeing addresses collective practices as
forms of resistance against power asymmetries – as activist strategies.
It focuses on the entangled dynamics between fleeing and occupying the
institution and the role institutional critique plays in these dynamics.
We will map out our different collective practices by posing questions,
such as: How can we understand the different ways the institution and the
collectives are linked? How to create collectives within the institution?
How can collectives flee or occupy the institution? Who can flee and
where to? How do institutions appropriate and destroy collective
structures?
In June 2019, I held the workshopcooking, playing and sharing at the
symposium sharing/learning: methods of the collective in art, research
and activism by the DFG-Graduiertenkolleg “Das Wissen der Künste”, Berlin
University of the Arts (UdK), at/in cooperation with District * School
without Center.
I invited guests to explore how to come together spontaneously,
creatively and intuitively for preparing a feast without previously
knowing the recipe and without a recipe. The main idea was how to make a
meal with the ingredients, we would have available, and share it between
the participants of the event. Noncooking Knowledge was required. As it
usually happens in my proposals, the practice has taken other directions.
What are the reasons behind a newfound popularity of collectives within
art economies? Could it be that collective practices are a necessary
answer to the challenges faced by (creative) workers in late capitalist
society? To reflect these questions, we take this text as a starting
point to try to critically assess our own personal history as an internetbased
research collective.
This text was part of the opening to the symposium sharing/learning:
methods of the collective in art, research and activism and was read on
28th June 2019, in English, by two members of the organizing team, as
introductory words. The text deliniates the central questions from which
the two-day gathering arises, as well as its methodologies and actors.
Many formulations originate from previously written concept papers, which
were used to present the project for various purposes. These in turn are
informed by the many conversations that took place within the
organizational team – a group of people whose constellation was shifting
along the way – orally as well as in writing.
In response to this issue’s call to “engage aesthetic processes of
remembering,” this paper analyses Fair Play (2014), a stereoscopic 3-D
cinema installation by Toronto-based filmmaker Ali Kazimi. Produced in
conjunction with the centennial anniversary of the arrival and detainment
of the Komagata Maru steamship in Vancouver, British Columbia, Canada,
the installation engages in an act of critical commemoration by imagining
the lives of members of the South Asian diaspora affected by this
incident. I argue that by centering affect within the formal and
conceptual framework of the installation, Kazimi produces a decolonial
aesthetic that restructures our relationship to this past, bringing to
the fore ways of living and knowing that had previously been devalued and
violently erased by colonial agendas and neoliberal art historical
critiques.
‘Looking Back Forward_Quip Nayr’ is based on the Aymara concept of time
and space called ‘qhip nayr’. As the Bolivian sociologist Silvia Rivera
Cusicanqui refers to it, ‘quip nayr’ is a way of looking into the past to
orient your path to the future. I use this concept to reflect on
processes of change, concerning language, identity and place. Expressing
identity on fabric recuperates my ancestors’ tradition from the Andean
region in Abya Yala (Latinamerica). The layering of textiles is inspired
by Gloria Anzaldúa, who uses fabrics as a synonym to talk about the
construction of identity in her concept ‘Haciendo Caras’.
For Issue 8 of wissenderkuenste.de, filmmaker Ali Kazimi has contributed
five images from an anaglyph version of his installation Fair Play. The
principle is simple: Each stereo image consists of a pair of images: one
for the left eye and the other for the right eye. All stereo viewing
systems seek to isolate the images, so the left sees only the one
intended for it, and the right sees the one intended for it. Our brain
creates the perception of a 3D image while viewing a 2D screen by fusing
these two slightly offset images together. Fair Play brings together all
strands of Kazimi’s research including stereoscopic 3D filmmaking,
stereoscopic 3D photographic history and images, as well as early
twentieth-century Canadian immigration history and colonialism.
With her photographic series Character Recognition (2006–2007) U.S.
artist Myra Greene examines historical constructions of race and racist
ways of looking from a perspective that undermines the assumed neutrality
of photography. She transforms the old ambrotype technique and encourages
to reflect on the power that visual technologies hold over the
representation of race and identity. Greene recalls yet disobeys
nineteenth-century ethnographic visual practices and looking
instructions, creating a technical and metaphorical deferral of the past
into the present and of the present into the past. Her photographic
practice unveils the ongoing violent effects of nineteenth-century
scientific racism on present-day bodies and embodied ways of looking. At
the same time, Character Recognition gives new life to the archives of
visual colonialism and experiments with photographic representation and
body memory as tools for decolonial options of non-normative (visual)
spaces.
Memoirs of Saturn
(2020)
In a set of para-fictional texts which interweaves the life of cultural
historian Dr. Shahidul Zaman with key moments in the ruptured history of
Bangladesh, the artist Omar A. Chowdhury, builds a reflexive mirror to
examine the nature of memory, of historiography, and the processes of the
art system. Recounting the history of an exhibition that was censored and
closed down in Dhaka in 2016, Chowdhury constructs a narrative that
doubles back on itself along multiple axes of the personal and public as
he and Dr. Zaman delve into the uncertainties in the presentation of
identity, the recollection of history, and the compromises of political
commitment.
In this work, I relate to the path of conocimiento, a concept developed
by Gloria Anzaldúa, which is a form of spiritual inquiry/activism,
reached via creative acts—writing, art-making, dancing, healing,
teaching, meditation, and spiritual activism. In writing and drawing, I
weave lines to different realities: the rural upbringings of the women
who raised me, my migration from the Third World, the meaning of home and
belonging, and my connection to all that exists on the planet as
political consciousness.
Looking at examples of presenting practices in Berlin and Toronto, this
essay sketches the difficulties that arise when embarking on a curatorial
practice with a decolonial impulse. This text is a partner to “On
Smuggling and Drawing. A Conversation in Blocks”, a dialogue between
curator Juana Awad and artist Luisa Ungar, written in 2020 and appearing
in the publication Künste dekolonisieren. Ästhetische Praktiken des
Lernens und Verlernens (edited by Julian Bauer, Maja Figge, Lisa
Grossmann, Wilma Lukatsch; Berlin, Transcript Verlag, forthcoming.)
But while the dialogue focuses on Ungar’s creation process of the over
one hundred original drawings intervening throughout the publication,
this essay brings to the forefront Awad’s questions about, and
experiences and observations with the mingling of the curatorial and the
decolonial, from her perspective as a curator and cultural worker.
Within documentary practices the relationship between fact and fiction is
constantly renegotiated. The films and videos by John Smith address this
relationship in a special way, disarrange it, and in doing so, reveal the
conditions of producing filmic truth. We invited John Smith to show his
films and comment on them in this regard. Here we present audio
recordings of his statements and short descriptions of the films he
referred to. In the following text, film scholar Volker Pantenburg points
out the importance of John Smith’s voice in his films, it creates a
reflexive level. In a similar way, the audio files create a commentary
level for the films in this article. Additional drawings by the Berlin
based artist Maxim Bauer illustrate the conversational character of the
evening.
07.11.2016 Reconsidering the Shape of Evidence: Visual Documents in and Beyond Contemporary Art.
(2017)
Sophie Berrebi discusses in her lecture the use of documents in the
visual arts in the first decade of the 21rst century. She focusses on
artists, who shed light on the potentials, mechanisms and traditions of
analogue forms of documentary practices in contrast to the contemporary
emphasis on the usage of digital media. In doing so they question the
status of art works as well as of documents and the relationship of
museums and archives. We present here the presentation manuscript of the
lecture and add the notes taken by two members of the research training
group. This most common kind of documentation of lectures in most
scientific disciplines points out the processes of selection und
accentuation in listening and recording.
Scientific experiments with documenting and archiving sound resulted in
the creation of diverse techniques which were eventually used beyond the
sciences, too. By addressing the poetics and politics of scientific sound
archives an institution comes into focus which is at the intersection of
art and science. While Viktoria Tkaczyk analyzed sound recordings from
the perspective of cultural studies, Gill Aubry presented his artistic
work with sound archives. Here, the evening is documented by photographs,
documentation of Gilles Aubry’s works and the transcription of Aubry’s
lecture.
No-Win Situation is an interdisciplinary exhibition, which took place from May 14th to May 16th 2021 in the Treptower Ateliers. Students, lecturers and alumni from the Universität der Künste Berlin showed their works.
In response to the current situation and beyond, the participants tried to find new forms and ways to approach media that can do justice to the fast-paced character of a human-made downfall. That is what we call "the pessimistic view“: The internet creates a network that is no longer comprehensible. Nature is burdened until the consequences harm the humankind itself. The market creates dynamics that no one can control. Regardless of the Covid-19 pandemic, there are more than enough reasons to be pessimistic about the world.

The exhibition catalog tries to link various artistic and creative positions. In terms of design, the question arises to what extent it is possible to reproduce new media but also to interpret them in a documentary print publication – a search for the best way to transport the essence of an artwork, especially when it has more to it than a visual part. The individual artwork is presented in a unique layout, approaching every work with a different design concept which is asking for the right visual language to communicate what is important.
The paper presents a novel method of multiclass classification. The method combines the notions of dimensionality reduction and binarization with notions of category prototype and evolutionary optimization. It introduces a supervised machine learning algorithm which first projects documents of the training corpus into low-dimensional binary space and subsequently uses canonical genetic algorithm in order to find a constellation of prototypes with highest classificatory pertinence. Fitness function is based on a cognitively plausible notion that a good prototype of a category C should be as close as possible to members of C and as far as possible to members associated to other categories. In case of classification of documents contained in a 20-newsgroup corpus into 20 classes, our algorithm seems to yield better results than a comparable deep learning "semantic hashing" method which also projects the semantic data into 128-dimensional binary (i.e. 16-byte) vector space.
In this article, the Moscow Conceptualist Vadim Zakharov reflects on the intertwinement of his artistic practice and his work as book designer. One of the main insights is that, for Zakharov, art becomes interesting when it emerges from, and yet goes beyond, work. This transgression is minimal, but it is founded in the particular experience of, and reflection on, work. Zakharov’s knowledge of book design becomes a means for his artistic expression. This article implies a critique of the indeterminate potentiality of the artist, herewith questioning the post-medium condition of art.
Mostly autobiographical, this article describes the development of Free Jazz in the Soviet Union and how its social status changed since the 1980s. Letov and most of his Free-Jazz colleagues were engineers and chemists. At their workplace the involvement with Free Jazz was well supported and promoted, for example, through the reduction of working time. For Letov, making music in his free time was a conscious decision and corresponded with his ideal of ‘free art’. However, in the 1990s this changed dramatically, and the consequence of the liberalization of the art and labour market led to a commercialization of Free Jazz.
This essay attempts to draw out the implications of Alfred Sohn-Rethel’s Intellectual and Manual Labour for the consideration of art. This is not something Sohn-Rethel intended or invited, but the aim here is to proceed immanently: by simply extending his critique of Kant’s epistemology to Kant’s aesthetics. The result is a critique of Kant’s influential account of aesthetic experience and art as an ideological form of commodity exchange abstraction.
The British Library holds, in the legacy of John Wallis, six ciphered letters from the French Court to Count Lauzun in Ireland. Five of them, undecipherable by Wallis, were from Minister of War Louvois; their contents are still considered unknown today. However, not only is the plaintext copy of one of these letters held by the Service historique de la défense in Vincennes, but also is the nomenclator used for all five to be found in the Bibliothèque nationale de Paris. Another letter from Naval Minister Seignelay to Lauzun, which Wallis was able to decipher to a large extent, can be found in the Archives nationales de France. In this article, all six letters are published in plaintext, four of them possibly for the first time.
Within the application context of interior spaces, this thesis investigates the emerging area of body-driven energy harvesting technologies from the perspective of human computer interaction (HCI) design. Upcoming innovations in new materials and low-power devices have enabled the conversion of body movements such as steps and arm movements into electrical energy for powering small computational things. Everyday interior spaces such as public buildings or homes can be fitted with new materials that harness human kinetic energy to produce electrical energy. Recent developments in the area of engineering and materials science aim to make these technologies more efficient. However, research about the implications of implementing them in the everyday from the perspective of the experiences and interactions of the people adopting these technologies is highly under-explored. In order to examine this design space, this research proposes to identify emerging concerns and challenges brought by everyday engagement with electricity production that need to be addressed through an interaction design inquiry.
To investigate the above proposition, a design program situated between the field of human computer interaction research and the practice of e-textile design is formulated with the aim to
investigate, at the scale of the interior, how static electricity can bring new perspectives and possibilities for ways of engaging with e-textiles, and designing interactions for energy harvesting with textiles.
The research sets up four research studies to systematically explore the design program. These research studies focus on four questions of how static electricity shapes e-textiles, how electrostatic textiles shape e-textile interactions, how e-static interactions shape everyday behaviours and how e-static studies shape energy interpretations. By developing a working knowledge of textile-based triboelectric generators, various body-generated electricity systems of different scales are envisioned. In the process of making, discovering and exploring different textile systems, questions regarding human interactions, material behaviours and the role of electricity in the everyday are discussed.
This thesis contributes to the practice of e-textiles by creating the foundational knowledge of using static electricity as a resource in e-textile design and development without needing specialised materials. Furthermore, it contributes to the field of human computer interaction research by further developing the topic of energy harvesting as a research area of interaction design. The thesis identifies two key areas for addressing challenges presented by body-driven energy harvesting with HCI which include considering accumulation of interactions over time and incorporating the electric properties of the body in interaction.
Additionally, practical outcomes of this research include:
1) www.estatictextiles.cc- An online handbook for learning about and working with static electricity and e-textiles which includes tutorials and examples from the research process.
And 2) E-static textiles prototyping board- A prototyping board developed for easy integration of static electricity and textiles to be used as an educational tool for designing and prototyping electrostatic energy-related interactions.
Repetition of morphological or lexical units is an established technique able to reinforce the impact of one's argument upon the audience. Rhetoric tradition has canonized dozens of repetition-involving schemas as figures of speech. Our article shows a way how hitherto ignored repetition-involving schemata can be identified. It shows that certain classes of repetitive figures can be represented in terms of specific sequences of integer numbers and vice versa, how specific sets of integer numbers can be translated into sets of regexes able to match repetition-involving expressions. A "Shakespeare number" S is simply defined as an integer with at least one repeated digit in which no digit bigger than X can occur if ever a digit X had not yet occurred in S's decimal representation. Hence, 121 is a Shakespeare number, while 123 or 211 are not. A set of "entangled numbers" is subsequently defined as a subset of "Shakespeare numbers" with an additional property that all digits which occur in them are repeated at least twice in the decimal representation of the number. Thus, a 1212 is an entangled number while 1211 is not. A complete set E of entangled numbers of maximal length of 10 digits is subsequently generated and every member of E is translated into a regex. Each regex is subsequently exposed to all utterances in all works of William Shakespeare, allowing us to pinpoint 3367 instances of 172 distinct E-schemata. This nomenclature may allow scholars to lead a discussion about schemata which have escaped the attention of classical interpretators.
Digital education: ”education-with” / ”education-about” distinction and the teleological definition
(2020)
Despite being an object of multi-billion public policies and private sector initiatives, the term ”digital education” seems to lack a clear, unambigous, lexicon-ready definition. A closer analysis reveals that in common parlance, the term is used to denote phenomena related to overlapping but distinct topics like ”technology”, ”media” or ”informatics”. Such polysemy implies an overall lack of
clarity which a public debate about education policies should rather avoid. For this reason, we propose to start sorting things out by defining the term ”digital education” in terms of dichotomy of two subordinated concepts, which we label as ”education-about-digital” and ”education-with-digital”. Postulation of this dichotomy combined with analysis of "school's mission" as defined in the legal codices of Land Berlin naturally leads to ”teleological definition” which delimits the concept of digital education in terms of its ideal human result.
Nowadays, society is becoming increasingly conscious of the adverse effect of energy use on the environment, contributing to the depletion of fossil fuels and increasing global warming. Because of the substantial contribution of building energy to these concerns, the intention should be not only to improve building energy efficiency but also to promote the use of renewable technologies, especially solar energy. Today building-integrated photovoltaic (BIPV) and building-integrated solar thermal (BIST) technologies are recognized by building designers as innovative technology for clean energy and greenhouse gas reduction, especially in cities, where multi-story buildings are dominant with limited roof area.
For the Mediterranean area, the high level of solar radiation and plentiful sunny hours make it appropriate for solar system installation, however, the development of solar energy is still limited. Moreover, due to the high population growth rate, lack of local resources, high energy price, and urbanization, one of the priorities in the Mediterranean area is to promote the energy efficiency of the building both on the supply side and demand side.
Therefore, this research aims to investigate the potential of installation of the photovoltaic (PV) and solar thermal (ST) technologies in the new multi-family residential building envelope in the Mediterranean area, taking Amman, Jordan, as a case study. The focus of this research is on the typical multi-family residential buildings in Amman, as it is the city where about 50% of the new construction in Jordan is taking place, and the residential buildings are the major consumers of energy and electricity in Jordan. The multi-family buildings also form about 75% of the total housing stock in Jordan. The typical multi-family building studied here is composed of five main floors, contains ten residential apartments; the area of each apartment is 150 m2. It is assumed that the building is located in a common residential urbanized zone in Jordan, with 6 m sides offset and 8 m back offset, assuming that one side is facing the main street, and all the buildings have a maximum allowable height of 15 m. All the architectural parameters related to the multi-family buildings have been defined through analyzing the residential building stock in Jordan.
In order to achieve the research aim, the possibility of reducing the energy demand of the typical multi-family building in Amman, Jordan, through passive and architectural design strategies was firstly investigated. After that, different performance criteria were evaluated, mainly quantitative criteria including energy consumption, energy production, and life cycle assessment (energy, carbon, cost). In addition to the qualitative criteria, including visibility and functionality, the purpose here is to emphasize the substantial function of BIPV systems. Each performance criterion was assessed alone. Then, all the performance criteria results were presented in a decision support matrix, which can be used as a comparison to evaluate and identify the solar system's application of choice, based on the criteria of the user. Moreover, a new energy index was formulated to evaluate the overall annual energy performance of BIPV design in terms of multifunctional effects on building energy.
Different methods were adopted in this research; the qualitative criteria were evaluated based on the literature review analysis, while the quantitative criteria were evaluated by using different simulation software, previous literature review, and spreadsheet calculations.
Literature review analyses were conducted in order to identify the relevant possibilities and the aesthetical solution the market offers, and the multiple benefits for PV and ST integration. The knowledge acquired from this part played a significant role in choosing and designing the proposals of PV and ST installation into the multi-story building envelope. Regarding the simulation studies, different building and energy simulation software was used to simulate and optimize the energy performance of the typical multi-family building in Amman, Jordan, through passive and architectural design strategies, as well as to find out the optimum design of the energy system in terms of energy performance (energy demand of the system, and solar energy fraction), and to investigate the energy-saving potential of PV and ST systems with various designs (tilt angles, azimuth, installed area, etc.). For the building energy simulation, each zone in the building was modeled as a space of its own. The energy demand was calculated on an hourly basis for a period of a whole year. The results from the simulation analysis, related literature and guidelines were adopted to conduct a life cycle assessment through spreadsheet calculation, to determine the long-term performance in terms of energy and carbon emissions, as well as cost considerations, taking into account the current market practice. The cradle-to-grave approach was adapted for the environmental life cycle assessments.
The general conclusion of this research is that installing the PV modules into the multi-family buildings envelope in Amman, Jordan, makes a positive contribution in terms of energy performance, as PV systems can cover up to 97% of the new building electricity demand when they are installed on both the roof and south façade, and up to 43% is covered by installing the PV modules into the south facade. Regarding the environmental life cycle assessment, the results proved the carbon saving potential of all the proposed PV systems, as the energy payback time (EPBT) is between 1.5- 3.5 years and the carbon payback time (CPBT) is between 3.4- 7.8 years. However, for the life cycle cost assessment the result showed that due to high capital cost and low cost of electricity, neither system is currently feasible for investment, as the payback time (PBT) is between 9.0- 16 years. However, with future advances in each system and more efficient designs, the payback periods would become tangible and therefore yield better performances. Lastly, the results were used to derive a decision support matrix aimed at providing a friendly approach to facilitate the implementation of solar building applications.

Abstract:
In his book ‘Noui et singolari modi di cifrare’, Giovan Battista Bellaso presents to his readers three challenge ciphertexts. Two of them are based on a polyalphabetic cipher with a mixed primary reciprocal alphabet and a long key, whereas the third one uses four independent homophonic substitution alphabets which change after each word. A successful approach to solving these ciphers, to which Bellaso gave the name ‘terzo modo’ and ‘quarto modo’, performs a simulated annealing attack directly on the primary alphabet respectively the four homophonic alphabets at once. This paper focusses on the various applied fitness functions. The solutions for the ciphertexts are given and finally discussed, with a view toward the possibility of a hidden message within the plaintexts.

In view of growing concerns on climate change and temperature extremes, there is a need to explore novel methods that provide thermal comfort in architecture. Latent heat thermal energy storage with phase change materials (PCM) has been widely researched in last decades in the field of energy technology and proved beneficial for reduction and shifting of the thermal loads and improving the overall thermal storage capacity of building components. Although a variety of PCM containments have been investigated for indoor cooling applications, the examples of exposed, design-oriented macro-encapsulations are rare. This paper presents a study of visible, suspended ceiling encapsulations for passive cooling, made of glass and novel bio-based PCM. The aim is to provide an overview of correlations between basic containment geometries and their thermal behavior that serves as a base for the further design of custom-made PCM macro-encapsulations. An experimental set-up of test boxes is developed for thermal cycling and a comparative analysis of the thermal performance of varied PCM encapsulation geometries. The study concludes that the containments with the large exchange surface and the small thickness offer an optimal material distribution for the temperature reduction in the box. Based on experimental results, suggestions are made on further formal strategies for the design of cooling elements for local thermal regulation.
New methods for designing with phase change materials (PCM) could widen the range of applications of passive systems for indoor cooling in architecture. This paper investigates material and formal strategies for generative architectural design that support the thermal performance of PCM. Dendritic geometry of PCM encapsulation with a large surface area per unit volume is proposed for enhancement of the heat transfer between PCM and surroundings. The prototype of the PCM ceiling component is digitally designed, manufactured in glass and tested in an experimental set-up for thermal cycling. Correlations are made between geometric configurations and cooling performance of dendritic and spherical PCM containments. The presented methodology integrates tools and techniques from digital design and energy technology, with an aim to contribute to novel PCM-based concepts for local thermal regulation in architecture.
When going deep into the area of sustainability and looking at the crosslinks that open up regarding the practice of design, a dark narrative appears whereby sustainable design is a failing practice, either aiming too high by trying to tackle global, inter- and intragenerational challenges, or aiming too low by focusing on, for example, material impacts of new products and services; this narrative appears to have an upper hand over one that is more positive and constructive that sees the strengths and potentials that design can bring to the challenges of sustainability. While the growth-oriented sustainable development discourse still dominates the way sustainable design is practiced, there are other streams with a more holistic view of sustainability. These streams are rooted in a post-growth / no-growth or strong sustainability discourse, which are slowly making their way into design practice through the guise of sufficiency, resilience and activism with a common theme of sharing knowledge, allowing citizens to be an active part of their community.
The dark narrative of sustainability in design as well as the call for designers to transform a practice of “un-sustainability” into one that allows “futuring”, leaves most of them shrugging their shoulders in light of how to implement the theoretical (utopian) requirements into their own practice. I argue for providing a different, more positive narrative, moving past the finger-pointing attitude towards reminding oneself what the practice of design in the context of sustainability can bring to the table.
Why there are new directions in sustainable design is largely because design has broadened beyond its product and service fixation towards a more process-oriented practice and an awareness of the impact designers have on this world. In these processes, designers are often taken outside the boundaries of growth-oriented economic progress towards social progress. They are continuously reminded that they cannot operate outside of a societal context and that their work has an impact on the Earth’s dynamic equilibrium (however small it might be).
Thus, the aim of my work is to re-frame sustainable design as a default configuration, stripping it from the unwieldy term of sustainability and extracting its core features of transformation, participation and future-focused thinking. Considering this core configuration, design is bound to be situated between anthropo- and eco-centricity, putting into question current user- and human-centric design approaches that tend to marginalize the everyday context and wider implications of the designed product or service.
Through an investigation that spanned the last five years, I have come to realize that sustainable design has nothing to do with a specific practice, but rather with a mindset which is, at its basis, tied to ethical considerations rooted in everyday life. It is moreover tied to broad, interdisciplinary knowledge that is needed to grasp the interconnected and global challenges that lie ahead. To make this point, in my work I am retracing the steps from the early roots of sustainable design within the sustainability movement towards its radical opening in different directions such as design activism, transformation design, design for social innovation and participatory design.
Furthermore, I propose a re-framing of the practice of sustainable design, (tentatively) linking it with a research-through-design approach and subsequently, through the design case, constructing a dynamic, interdisciplinary action repertoire for designers.
When framing this renewed idea of sustainable design, not only do the two dimensions of transformation and participation almost automatically appear in the current discourse, but also the notion of opening up contexts through design in a way that is directed towards possible (sustainable) futures becomes apparent. Several overarching perspectives resurface in the course of this work:
1 Opening – How can designers open access to contexts, tools, knowledge and technology through collaborative, interdisciplinary action?
2 Making – How can designers provide processes to involve stakeholders in critically assessing and making possible futures?
3 Transforming – How can designers transform contexts and situations from one state to a preferred one (and how can they facilitate the negotiation-processes tied to them with regards to social equity and intra-generational justice)?
The topic of transformation and future-focused thinking is currently engaging most of design, not exclusively sustainable design, and this thinking seems to provide an underlying idea that design may be able to provide at least part of the skill-set required to cater to this transformation. It is, however, not only the context and situations design claims to transform, but also user behavior and market incentives. In this research, transformation is viewed as a careful byline to a project which spans almost six years and is now coming to a close.
The design case for this research is the project Neighborhood Labs which has been run by an interdisciplinary group of design researchers, citizens and other stakeholders in a central, but isolated area in Berlin’s Mitte district. It incorporated the development of a research concept and experimentation process which builds on a participatory design methodology as well as a living lab approach. It was planned open-ended with the potential of stakeholders taking over after the official end of the research project.
In terms of sustainability, the subject and guiding theme of sharing and collaboration was the baseline of the design phases and iterations. While focusing at first on the sharing of concrete objects in a specific community of practice, there was a shift to sharing knowledge, as well as to the empowerment of citizens to impact local decision-making processes, a much fuzzier subject than the sharing of objects or services. The project was run in three intertwined phases:
– Sharing phase / Neighborhood lab: Setting up and running a living lab. Investigating the context and building the infrastructure. Approaching the neighborhood and designing tools for gathering insights about needs and issues within it while drawing active citizens towards the project. After this step, insights inform the research process and help focus the research question further. This phase produced several concepts and sketch prototypes in collaboration with the stakeholders of the Fischerinsel, Berlin.
– Infrastructure phase / Designing infrastructures & fostering change: Designing and testing participatory tools such as the Hybrid Letterbox, an analog-digital bridge device, in order to discuss and evaluate questions of social cohesion and communication within the neighborhood and to activate citizens for involvement in these issues.
– Transfer phase / Design transfer: opening up the context and pushing the methods and tools outside of its initial project and creating new instances thereof.
As I am reflecting on the process of a long-term project now behind me, such as working through trial-and-error phases, prototypical research-through-design attempts and the immersion in the Fischerinsel-context that the research group grew a part of, several key directions in the dealing with and conveying of sustainability challenges appear.
On a practical level, these directions materialize in the categories of investigative action, participatory tools and workshop formats, which are distilled from a broad range of interdisciplinary actions conducted over the course of the research, leading to an action repertoire for transformation which I propose as one of the outcomes of my work.
On a theoretical level, I argue for sustainable design by default, meaning sustainability as an inherent, embedded goal of any design process, integrating a research-through-design mindset in sustainable design or vice versa. In further steps, this entails restructuring the way we teach design and how design practice is informed throughout its process.
Elastic gridshells are celebrated for their striking biomimetic curves, long spans and efficient material usage. Constructed from a grid mechanism of slender beams, an elastic gridshell is assembled on a flat surface then repositioned into its final curved shape after which stabilising elements are added and the structure becomes a stiff load-bearing shell.
While elastic gridshells are efficient in their built-state, the established methods with which to erect them (‘lift up’, ‘push up’ and ‘ease down’) are associated with substantial complexity, cost and time which inhibit their adoption. The central research question of this thesis asks whether elastic gridshells can be erected by means of pneumatic falsework (i.e. ‘inflate’), if so how and what would be the implications of doing so.
The work presented in this thesis proves that the pneumatic erection of elastic gridshells is not only feasible but can offer many advantages (such as speed of erection, structural robustness and architectural qualities) over existing shelters for humanitarian, event and architectural applications. A literature review is presented on the historical precedent for this novel method. The computational challenges of simulating the complex erection process are investigated in depth leading to the development of bespoke simulation methods based on the novel application of a projection-based dynamic relaxation solver.
Case studies and a benchmark compare state-of-the-art finite element solvers based on both global and local stiffness revealing their quantitative and qualitative differences giving some indication as to the future of finite element modelling for the built environment in engineering, research and education. Innovative prototypes of augmented and virtual reality engineering tools for education are presented as wider reaching applications of the novel simulation method developed for this thesis.
The simulation methods developed to answer the central research question deliver valuable findings relating to the scope of feasibility and the practical execution of the novel method including: suitable shapes and sizes of shells, ‘trigger’ pressures required, the function and importance of tethering cables during erection, development and detailed analysis of erection sequences and identification of material suitability and performance criteria. One small and two full-scale physical prototypes were built which validate the novel computational methods to a high level of precision, offer practical detailing solutions and demonstrate the architectural and humanitarian potential within the pneumatic erection of elastic gridshells.
This dissertation offers a critical engagement with design’s implication in the ontological constitution of gendered, racialized, subjugated bodies. To do so, it starts from a broad understanding of design as an activity that articulates modes of being in the world — and that, in so doing, also shapes itself. This approach is grounded on an interrogation of the political motives that permeate and inform design processes; I take particular interest in how these have been manifested throughout the history of birth control technology.
Starting from this background, I outline and propose the concept of technoecologies of birth control — that is, spaces that emerge through the performances of co-constitutive material-semiotic actors, for the purposes of birth control. Throughout this dissertation, I identify two fundamental sets of actors operating within the technoecological space: bodies and things. The co-constitution of these actors is realized across historically, geopolitically, socioculturally, technoscientifically located performances; as such, technoecological actors are approached as relational, contextual and mutually structuring entities.
This conceptualization of technoecologies of birth control is informed by feminist and decolonial theories, and posits that these spaces are crucial for the establishment and sedimentation of biopolitical regimes of domination. Design is thoroughly implicated in the emergence of technoecologies of birth control, as it holds a crucial role in the management and regulation of bodies characteristic of biopolitical regimes of domination. In other words, design inscribes ontological meaning onto some bodies in detriment of others; it is with the sedimentation of these conditions that bodies become coded as ‘naturally’ or ‘fundamentally’ different. The constitution of difference amongst material-semiotic actors in technoecologies of birth control is thus articulated by design; in other words, it is the result of a planned, deliberate inscription of ontological meaning.
My interrogation of design’s role in the constitution of subjugated bodies occurs within the scope of these technoecologies. Starting from this framework, I discuss the insights offered by a series of experiments (‘Yarn Sessions’ and 'Oniria') conceived as both explorations of the technoecological space, and speculations on the instability of the social constitution of bodies by design. My theorization of technoecologies of birth control happens, thus, through a process of research through design — that is, a process in which theory and practice are deployed as mutually informing forces in design research. Through the analysis of these design experiments, I propose three fundamental aspects of the performances of material-semiotic actors within technoecologies of birth control: relativity, opacity, and duplicity.
The Central Library of the universities TU Berlin and the UdK Berlin turned ten years old in 2014 and its wayfinding system hasn’t been updated or redesigned since. Actually, it wasn’t planned as a system. This orientation system has been developed spontaneously in different methods since the beginning. The staff that works in the library developed it based on their daily necessities. There was no main objective, so it grew in an organic form. Because of this, the current system presents problems that decrease its performance and effectiveness.
For this project I would like to focus of the current wayfinding system of this library and its users in addition to a posterior redesign proposal.
Decolonizing the Earview of Design: Listening Anxieties and the Apparatus of Auditory Governance
(2018)
This dissertation attends to the intersection of sound, material culture, racism, and police violence in Brazil from a decolonizing perspective. With a focus on theories informed by cultural and sound studies, it unravels the contingent arrangements through which certain designed objects and practices function as material-discursive nodes for the normalization and perpetuation of racialized violences. To explore these ideas, it reads design—a field of knowledge and a set of practices—as a material-discursive apparatus, accountable for not only the results but also the conditions of possibility for any research endeavor.
The main driving force of this work is the identification and evincing of ‘listening anxieties.’ These emerge through enactments of political consensus, policing, and compliance; the articulation of these three in institutional, designerly, as well as everyday practices is what this research identifies as the Apparatus of Auditory Governance (or AAG). More specifically, I look at three manifestations of these auditory governances in contemporary Brazil—from the early 2000s to the judiciary Coup d’Etat of late 2016. These range from the criminalization of jukeboxes by a Military Police acting outside the scope of written law in so-called ‘pacified’ neighborhoods in Rio de Janeiro, to the construction of a seven kilometer-long acoustic barrier in the city as a device for urban segregation, to the deployment of sound bombs as devices for the enforcement of silence by the same police force in São Paulo.
The articulation of auditory governances, however, is not fixed; rather, it shifts and mutates to account for distinct and diverse experiences of listening. These shifts are what this work calls earviews: a conceptual orientation which determines the “listening point” where narratives and perceptions of auditory reality unfold from. The AAG, articulated and deconstructed at the intersection of distinct and conflicting earviews, forms the main method of this dissertation, and is of particular interest for sound and design studies. By understanding the earview as an asset of and for designing, it is possible to interrogate the role of design in the enforcement, reproduction, and normalization of sonic violences, and the erasure of other(ed) narratives of listening. Rather than simply evincing the hegemony of normative—qua racialized—earviews, I intervene by reading them through first-person accounts and storytelling stemming from fieldwork with artists and activists in Brazil, as well as from two movies by Brazilian directors—O Som ao Redor (2012) and Branco Sai, Preto Fica (2014). These intersections are further complemented by a semi-fictional narrative created throughout five collective pedagogical sessions fusing designing and fabulation. This format, named “Yarn Sessions,” is my methodological proposition for design research in this work.
This research started out by posing three broad questions relating to the connection between auditory practices—i.e. sounds and their social, cultural, and political engagements—and the design of listening devices. It asked: what is the contribution of design to the politics of mediated listening and its devices? What might be the possible, probable and/or preferable enactments of the political agency of designed listening devices? These initial questions are all addressed by this work, and have shifted from their initial form as a general investigation on the entanglement of design and listening, to offer an inquiry and an intervention on violences enacted with and through sound.
This work thus participates in a re-historicization of the colonial underpinnings of design, while at the same time offering a decolonizing methodological proposition for design research and design studies with a sound and listening-oriented locus. It demonstrates that the material conditions of sonic violence—from architectural planning to transitional/illegalized sound objects to the development of weaponry—are a form of ontological design (cf. Anne-Marie Willis) which succeeds by making its own colonial and racialized ethos discursively and materially invisible. This ontological enunciation demands the accountability of the designer as both producer and reproducer of racialized/colonial phenomena in the making of their own practices.
Yet this research does not align itself completely with discourses from the “ontological turn” or “new materialisms” in philosophy (cf. Karen Barad), insofar as these often undermine and erase the role played by coloniality and “racialized assemblages” (cf. Alexander Weheliye) to the constitution of its own ontologies and epistemologies. My proposition for design understands the field to constitute in itself an ontoepistemology (cf. Willis, Gloria Anzaldúa), albeit reading such ontological alignments through decolonial and critical race studies. In so doing, it opens up a new field of inquiry in which sound studies and decolonial thought inform designerly inquiries into material culture not only for the evincing of specific material-discursive phenomena (e.g. sonic violences), but also for intervening on them with intersectional and decolonizing frameworks.
Introduction
Following their first meeting in Düsseldorf in 1961, Joseph Beuys and Nam June Paik began their lifelong series of artistic collaborations so-called EURASIA. Sharing a common interest in Europe and Asia, they started to consider Europe (=West) and Asia (=East) as one continental culture, and tried to connect them as EURASIA.
Containing Europe and Asia, Eurasia is one continuous mass of land. Europe and Asia, or West and East are merely imaginary divisions, but once they are named Europe and Asia or West and East, this fixed division makes it difficult to understand that these two areas are in fact one continent with common roots, and that they developed through mutual influence. To realize the continuity of Europe and Asia and understand how to connect these two regions is becoming an urgent question.
In our globalized world, it is becoming impossible to uphold protection through the entity of the nation-state, which defines the enemy as being outside the nation. In order to find an alternative to the nation-state, we need to look back in history and restructure the world on a more abstract level; in other words, the sublation of Westphalian sovereignty which developed after the Thirty Years’ War is now required.
Also if Asia becomes one political entity, just as Europe is becoming one political entity, the tension between Europe and Asia will be intense; it will be no different from that between nations, which caused two World Wars. As Asia, a large part of which was once colonized by Europe, begins to gain political and economical power, it becomes necessary to prepare a plan to reconcile Europe and Asia. Meanwhile, if Eurasia is united as an expansion of the nation-state, the result may be regional hegemony with a one-sided national perspective, similar to that of the Greater East Asia Co-Prosperity Sphere led by the Empire of Japan. The Eurasian Economic Union led by Vladimir Putin’s Russian Federation threatens to make the same mistake. Bearing in mind the fact that the bloc economy triggered World War II, to connect Europe and Asia while eschewing regional hegemony will be crucial for our co-existence in the 21st century.
Having endured World War II, both Joseph Beuys and Nam June Paik were aware of the contradictions of modernity and the nation-state which originated in Europe. They reflected on how to overcome divisions such as those between nations, between Europe and Asia in colonial history, and between East and West during the Cold War at that time. Eliminating borders, Beuys and Paik’s utopian vision of EURASIA is an abstract and archetypical metaphor for connecting Europe and Asia, West and East, or two opposite things into one, and it will give us a hint on how to overcome the divisions caused by modernity.

This thesis investigates and describes the design and structural behaviour of elastic gridshells. Elastic gridshells are shell structures composed of a single- or multi-layer grid of continuous profiles, which are initially straight and will be progressively bent until achieving an architecturally and structurally satisfactory geometry. Usually used as medium to large span surface structures, elastic gridshells present a wide variety in their surface geometry, grid configuration and materiality. One important structural criterion of elastic gridshells is the high residual stress to which they are subjected after the bending process. Using materials with high limit strain, the residual utilisation rate can be reduced. In the first part of the work, the structural aspects to be considered on the design procedure of elastic gridshells are described and identified on existing design approaches. Then, the mechanical properties of available materials, suitable for elastic gridshells, have been compared and application examples have been presented and illustrated.
Elastic gridshells offer significant cost and time advantages during the production, transport and construction processes. Nevertheless, the shaping of the initially flat grid also generates important bending stresses on the structures, reducing therewith their bearing capacity against external loads. In order to diminish the initial stresses, profiles with low sections and materials with low modulus of elasticity are usually chosen. However, this leads to a reduction of the global stiffness of the gridshell which can result in stability problems. With an optimisation of the grid pattern - orientation and arrangement of the grid profiles - a minimisation of the profiles’ curvature can be obtained and the load-bearing capacity of the gridshells improved. In the second part of the thesis, an optimisation method based on variational principles for regular and irregular gridshells is proposed and different case studies presented. The aim of using variational principles is to establish extremal functions which minimize the value of quantities related to particular grid properties. These properties are: the curvature of the profiles, the distance to a target surface geometry and the deviation of the edge lengths from a desired mesh size. The advantage of this method is that weighting factors can be applied to the grid parameters to be minimised, so that a variety of grid configurations can be established responding to different specific requirements.
The bending process and load-bearing behaviour of elastic gridshells can be analysed using three-dimensional finite element models. During the shaping of the profiles, internal forces are induced on the structure, so that the final equilibrium shape of the gridshell will be attained once its edges have been fixed, the bracing elements have been assembled and the external shaping forces have been removed. The goal of the numerical analysis is to quantitatively evaluate the geometry and material stresses resulting from the shaping process and the load-bearing capacity of the gridshell under external loading. In the third part of the thesis, the influence of the orientation and arrangement of the grid profiles on the residual stresses after erection process and on the distribution of forces and deformability of the gridshell under external loading are analysed on three regular anticlastic gridshells with varying grid pattern. Moreover, the potential and limitations of using tensile membranes as restraining and at the same time covering element of elastic gridshells are studied on a hemispheric regular elastic gridshell.
Numerical techniques are commonly used for the calculation of stress distributions and displacements of complex indeterminate bearing structures. Nevertheless, to model the elements they are composed of and the connection properties between them, simplifications and approximations are done. The purpose of the fourth and last part of the work is to analyse the influence of these simplifications on the results of the simulation and thereby recalibrate and benchmark the numerical models with physical prototypes. Two gridshells composed of GFRP profiles have been built: an irregular hemisphere of 10 m diameter, braced with a third layer of profiles, and a regular hemisphere of 5 m diameter, restraint with a tensile membrane. The prototypes have been loaded symmetrically and asymmetrically applying point loads at the grid nodes and the resulting nodal displacements have been compared to those calculated with the numerical models.
My doctoral thesis with the title „Rebuilt Rubble - Community Gardens in the South Bronx from 1970s to the 21st century: Common land use in the inner city from a socio-economic open space planning perspective” is focused on the assumption that people are longing for and are committed to a common urban open space land use form in the inner city – a hypothesis that I investigated by analyzing the development of community gardens in the study area South Bronx from the 1970s to the 21st century.
My thesis is contextualized in the research fields of social open space planning and urban design. The analysis is based on qualitative data collection that encompasses census data, plans, open interviews and participatory observation and includes the discussion of secondary literature regarding community gardens and urban open space development in the South Bronx.
Since the urbanization and industrialization at the end of the nineteenth century residential space in densely build-up inner cities, and especially in low-income neighborhoods, has been reduced often to a minimum, and privately usable open space is absent in many cases. Starting with the global economic recession of the 1970s in the urban centers of North American cities such as New York City there have been privately, but collectively used gardens created on public open land. These so called community gardens were started by low-income residents on vacant property lots in the vicinity of their apartments in order to improve their quality of life and in answer to the “neglect” of their neighborhoods by the government and municipality. Today there are about 600 community gardens in the metropolitan area of New York City and 44 gardens alone in the area called South Bronx, the study area of my thesis.
I analyze in my thesis the development of this common land use in the study area South Bronx from a social-economic and open planning perspective. The case study of my research is focused on community gardening and the “casita”, the small hut that low-income residents with Latin American and Caribbean cultural background build themselves out of found and recycled materials in many community gardens in the South Bronx.
My thesis researches the development of community gardens in the South Bronx since the 1970s influenced by often conflicting interests of various land use groups, residents and city planning agendas until today. It is a document of the humans’ need for common urban open space land use and of their commitment to the community garden land use form in the inner city.
Encountering the Digital: Representational and Experiential Embodiment in Tangible User Interfaces
(2014)
This dissertation is concerned with the concept of »embodiment« in the field of Human-Computer Interaction (HCI). It investigates the issue by the means of Research Through Design
(RTD).
The notion of »embodiment« has many meanings in HCI. It is therefore the aim of this work to contribute to its clarification. I propose a distinction between two major meanings: »embodiment« in the sense of »representation« and »embodiment« in the sense of how the experience of one’s socio-physical world is fundamentally grounded in having a living body. I propose to name these two meanings »representational embodiment« and »experiential embodiment«.
Having separated the two meanings, I then look at those moments in which they encounter: I investigate moments in which »embodied« users face »embodiments« of digital information. These moments of encounter appear to be a central aspect of Tangible User Interfaces (TUIs), which are often concerned with making digital information graspable. Therefore, I focus on TUIs, pursuing the question of how the design of the »representational embodiments« of digital information affects the user’s experience of the interaction.
RTD is a research concept that promises to offer a new, »designerly« perspective on a subject matter. There are different approaches to RTD, of which I have chosen Findeli’s model of Project-Grounded Research (PGR). I introduce RTD and PGR, contextualising them in their historical context. I underline the central roles of the prototype and the »project« in PGR. I also relate RTD to its academic reference points: action research and grounded theory. Afterwards, I transform my research question into a design question, namely how the »embodiments« of digital information could be designed in a way that is oriented to the users’ »embodiment«.
In everyday language, physical (e. g. »disk size«, »data mining«) and social metaphors (»smart phone«, »battery life«) are often used to describe concepts of interacting with digital information. These metaphors form the starting point of my investigation into TUIs that make digital information graspable through socio-physical manifestations – through shape change, weight shift, and life-like signals. I describe the prototypes and report several previous studies that were conducted with them. These assess, for example, the accuracy at which users could feel the shifted weight on the phone’s inside, or the experiences of users carrying the »living mobile« for a weekend.
I then report a comparative study of the three prototypes and three vibration-based comparison prototypes. In this study, I make use of the Repertory Grid Technique (RGT). RGT is based on so-called »personal constructs«, which the users name themselves, as to describe the prototypes (e. g. »knowledge required – easy to understand«, »biological – technical«, »exciting – boring«). The users then use their own personal constructs to rate the prototypes. The findings of the RGT study indicate that the interaction with the Shape-Changing Mobile, Weight-Shifting Mobile, and Ambient Life prototypes was experienced by the users as novel and interesting, but at times also as irritating, and even annoying. The mixed results from this study can be described as three »two-sided coins«: the interaction with the prototypes was rated as rich in associations, but requiring prior knowledge and, at times, disappointing. It was rated as permanent, but at times annoying. Lastly, it was described as cute, but sometimes creepy.
I conclude that the encounter of »representational embodiment« and »experiential embodiment« can open a conceptual space for interaction design that is rich in opportunities, but also rich in challenges. It is this space that I set out to explore with this dissertation.
In summary, the main contributions of this dissertation are a separation of different meanings of »embodiment« in HCI and a study of TUI prototypes that explore the encounter of these meanings.
