In this paper we propose an integrated immersive augmented reality solution for a software tool supporting spacecraft design and verification. The spacecraft design process relies on expertise in many domains, such as thermal and structural engineering. The various subsystems of a spacecraft are highly interdependent and have differing requirements and constraints. In this context, interactive visualizations play an important role in making expert knowledge accessible. Recent immersive display technologies offer new ways of presenting and interacting with computer-generated content. Possibilities and challenges for spacecraft configuration employing these technologies are explored and discussed. A user interface design for an application using the Microsoft HoloLens is proposed. To this end, techniques for selecting a spacecraft component and manipulating its position and orientation in 3D space are developed and evaluated. Thus, advantages and limitations of this approach to spacecraft configuration are revealed and discussed.
Based on experience in teaching programming, we developed the integrated development environment (IDE) 5Code especially to support beginners. As a first step, a simple, understandable formula was developed how to advance from the problem to the program in 5 operative steps:
read it → get it → think it → note it → code it.
In order to reduce the cognitive load of the learners effectively, 5Code was designed such that all 5 steps are permanently presented, accessible and executable. Thus, learners are provided with the entire programming context from presentation of the task via own notes and annotations to the code area. Learners can mark and annotate any part of the given task’s text; these annotations can be edited as notes with own comments. Furthermore, the notes can be dragged into the code area, where they are shown as comments in the coding language. Any modifications in the comments are synchronized between notes and code. 5Code is implemented as a web-application. It is used in university introductory courses on object oriented programming.
An international, collaborative investigation is undertaken to evaluate the relative merits and limitations of various numerical methods and experimental measurement techniques, specifically for the analysis of flapping-wing propulsion. A finite aspect-ratio configuration is extensively investigated, both quantitatively and qualitatively, in a low-speed wind tunnel. Direct force measurements are made, as well as time-accurate and time-averaged laser Doppler velocimetry and unsteady flow visualization. The reduced frequency, mean angle of attack, aspect ratio and Reynolds number are varied in the experiments. The experiment is numerically simulated using flatplate theory, two and three-dimensional panel codes, and two and three-dimensional Euler and Navier- Stokes solvers. The ability of each of the methods to capture important aspects of the flow physics are evaluated through comparisons with each other and the experimental data. Additionally, the comparisons indicate areas where further research is needed. The collaborative effort provides a survey of available capabilities and provides a fixed set of flappingwing data for others to compare against.
The discipline of engineering secure software and services brings together researchers and practitioners from software, services, and security engineering. This interdisciplinary community is fairly new, it is still not well integrated and is therefore confronted with differing perspectives, processes, methods, tools, vocabularies, and standards. We present a Common Body of Knowledge (CBK) to overcome the aforementioned problems. We capture use cases from research and practice to derive requirements for the CBK. Our CBK collects, integrates, and structures knowledge from the different disciplines based on an ontology that allows one to semantically enrich content to be able to query the CBK. The CBK heavily relies on user participation, making use of the Semantic MediaWiki as a platform to support collaborative writing. The ontology is complemented by a conceptual framework, consisting of concepts to structure the knowledge and to provide access to it, and a means to build a common terminology. We also present organizational factors covering dissemination and quality assurance.
This paper presents a conceptual framework for security engineering, with a strong focus on security requirements elicitation and analysis. This conceptual framework establishes a clear-cut vocabulary and makes explicit the interrelations between the different concepts and notions used in security engineering. Further, we apply our conceptual framework to compare and evaluate current security requirements engineering approaches, such as the Common Criteria, Secure Tropos, SREP, MSRA, as well as methods based on UML and problem frames. We review these methods and assess them according to different criteria, such as the general approach and scope of the method, its validation, and quality assurance capabilities. Finally, we discuss how these methods are related to the conceptual framework and to one another.
In today’s market research mechanisms multi modal technologies are significant tools to perform flexible and price efficient studies for not only consumer products but also consumer goods. Current appraisal mechanisms in combination with applied computer graphics can improve the assessment of a product’s launch in the very early design phase or an innovation process. The combination of online questionnaires, Virtual Reality (VR) applications and a database management system offers a powerful tool to let a consumer judge products as well as innovated goods even without having produced a single article. In this paper we present an approach of consumer good studies consisting of common as well as interactive VR product presentations and online questionnaires bases on a bidirectional database management solution to configure and manage numerous studies, virtual sets, goods and participants in an effective way to support the estimation of the received data. Non-programmers can create their test environment including a VR scenario very quickly without any effort. Within the extensive knowledge of consumer goods, marketing instruments can be defined to shorten and improve the rollout process in the early product stages.
A filtering model for efficient rendering of the spatial image of an occluded virtual sound source
(1999)
Rendering realistic spatial sound imagery for complex virtual environments must take into account the effects of obstructions such as reflectors and occluders. It is relatively well understood how to calculate the acoustical consequence that would be observed at a given observation point when an acoustically opaque object occludes a sound source. But the interference patterns generated by occluders of various geometries and orientations relative to the virtual source and receiver are computationally intense if accurate results are required. In many applications, however, it is sufficient to create a spatial image that is recognizable by the human listener as the sound of an occluded source. In the interest of improving audio rendering efficiency, a simplified filtering model was developed and its audio output submitted to psychophysical evaluation. Two perceptually salient components of occluder acoustics were identified that could be directly related to the geometry and orientation of a simple occluder. Actual occluder impulse responses measured in an anechoic chamber resembled the responses of a model incorporating only a variable duration delay line and a low-pass filter with variable cutoff frequency.

Problem frames are patterns for analyzing, structuring, and characterizing software development problems. This paper presents a formal metamodel for problem frames expressed in UML class diagrams and using the formal specification notation OCL. That metamodel clarifies the nature of the different syntactical elements of problem frames, as well as the relations between them. It provides a framework for syntactical analysis and semantic validation of newly defined problem frames, and it prepares the ground for tool support for the problem frame approach.

Acquiring human motion data from video images plays an important role in the field of computer vision. Ground truth tracking systems require markers to create high quality motion data. But in many applications it is desired to work without markers. In recent years affordable hardware for markerless tracking systems was made available at a consumer level. Efficient depth camera systems based on Time-of-Flight sensors and structured light systems have made it possible to record motion data in real time. However, the gap between the quality of marker-based and markerless systems is high. The error sources of a markerless motion tracking pipeline are discussed and a model-based filter is proposed, which adapts depending on spatial location. The proposed method is then proven to be more robust and accurate than the unfiltered data stream and can be used to visually enhance the presence of an actor within a virtual environment in live broadcast productions.
A new robust design for imperfection sensitive stiffened cylinders used in aerospace engineering
(2015)
We present a pattern system/or security requirements engineering, consisting of security problem frames and concretized security problem frames. These are special kinds of problem frames that serve to structure, characterize, analyze, and finally solve software development problems in the area of software and system security. We equip each frame with formal preconditions and postconditions. The analysis of these conditions results in a pattern system that explicitly shows the dependencies between the different frames. Moreover, we indicate related frames, which are commonly used together with the considered frame. Hence, our approach helps security engineers to avoid omissions and to cover all security requirements that are relevant for a given problem.
The authors present a security engineering process based on security problem frames and concretized security problem frames. Both kinds of frames constitute patterns for analyzing security problems and associated solution approaches. They are arranged in a pattern system that makes dependencies between them explicit. The authors describe step-by-step how the pattern system can be used to analyze a given security problem and how solution approaches can be found. Afterwards, the security problems and the solution approaches are formally modeled in detail. The formal models serve to prove that the solution approaches are correct solutions to the security problems. Furthermore, the formal models of the solution approaches constitute a formal specification of the software to be developed. Then, the specification is implemented by generic security components and generic security architectures, which constitute architectural patterns. Finally, the generic security components and the generic security architecture that composes them are refined and the result is a secure software product built from existing and/or tailor-made security components.
The Common Lisp Interface Manager (CLIM) is used to develop graphical user interfaces for Lisp-basedapplications. With the prototype of the CLIM interface Builder (CLIB) the programmer can generate code for CLIM interactively. The developing process will be fast and less prone to errors. With this new tool, the interactive rapid prototyping reduces costs of a specification phase. Here we present the concept and first results of the prototype of CLIB.

In a virtual reality environment, users are immersed in a scene with objects which might produce sound. The responsibility of a VR environment is to present these objects, but a practical system has only limited resources, including spatialization channels (mixels), MIDI/audio channels, and processing power. A sound spatialization resource manager, introduced in this thesis, controls sound resources and optimizes fidelity (presence) under given conditions, using a priority scheme based on psychoacoustics. Objects which are spatially close together can be coalesced by a novel clustering algorithm, which considers listener localization errors. Application programmers and VR scene designers are freed from the burden of assigning mixels and predicting sound source locations. The framework includes an abstract interface for sound spatialization backends, an API for the VR environments, and multimedia authoring tools.
A Sound Spatialization Server for a Speaker Array as an Integrated Part of a Virtual Environment
(1998)
Spatial sound plays an important role in virtual reality environments, allowing orientation in space, giving a feeling of space, focusing the user on events in the scene, and substituting missing feedback cues (e.g., force feedback). The sound spatialization framework of the University of Aizu, which supports number of spatialization backends, has been extended to include a sound spatialization server for a multichannel loudspeaker array (Pioneer Sound Field Control System). Our goal is that the spatialization server allows easy integration into virtual environments. Modeling of distance cues, which are essential for full immersion, is discussed. Furthermore, the integration of this prototype into different applications allowed us to reveal the advantages and problems of spatial sound for virtual reality environments.
We give an enumeration of possible problem frames, based on domain characteristics, and comment on the usefulness of the obtained frames. In particular, we investigate problem domains and their characteristics in detail. This leads to fine-grained criteria for describing problem domains. As a result, we identify a new type of problem domain and come up with integrity conditions for developing useful problem frames. Taking a complete enumeration of possible problem frames (with at most three problem domains, of which only one is constrained) as a basis, we find 8 new problem frames, 7 of which we consider as useful in practical software development.
The PSFC, or Pioneer Sound Field Controller, is a DSP-driven hemispherical loudspeaker array, installed at the University of Aizu Multimedia Center. The PSFC features realtime manipulation of the primary components of sound spatialization for each of two audio sources located in a virtual environment, including the content (apparent direction and distance) and context (room characteristics: reverberation level, room size and liveness). In an alternate mode, it can also direct the destination of the two separate input signals across 14 loudspeakers, manipulating the direction of the virtual sound sources with no control over apparent distance other than that afforded by source loudness (including no simulated environmental reflections or reverberation). The PSFC speaker dome is about 10 m in diameter, accommodating about fifty simultaneous users, including about twenty users comfortably standing or sitting near its ``sweet spot,'' the area in which the illusions of sound spatialization are most vivid. Collocated with a large screen rear-projection stereographic display, the PSFC is intended for advanced multimedia and virtual reality applications.

The Chylla–Haase polymerization reactor is widely accepted as a benchmark process for the evaluation of control strategies for batch reactors. In this contribution a control concept based on Exact I/O-Linearization is proposed and compared to a conventional cascade control structure. In order to adapt the exact linearization control strategy to various polymerization products and batch conditions, an advanced probabilistic inference algorithm (Sigma-Point Kalman Filter) is applied and investigated. Sigma-Point Kalman Filters have the major improvement of simplified implementation compared to local linearization methods (i.e. Extended Kalman Filter) because no analytical Jacobians are required. Stochastic simulation studies are introduced and show the effectiveness, accuracy and benefit of the control concept. Within several scenarios a satisfying robustness against structural errors in the underlying model equations for the nonlinear control law and the inference algorithm is demonstrated. Furthermore it is pointed out, that with little effort in reassembling the plant design, control performance can be improved significantly.
Die Handlungsfelder Sozialer Arbeit zu systematisieren ist nicht voraussetzungslos; aufgrund weitgehender Differenzierungen in der Praxis sind eine Gesamtübersicht sowie eine trennscharfe Benennung und Zuordnung kaum mehr möglich. Diese Entwicklungen berücksichtigt das Buch, indem es die bisherigen lebensalter- und lebenslagenbezogenen Systematisierungen um lebensraum- und lebenskontextbezogene sowie um disziplin- und professionsbezogene Handlungsfelder erweitert. Gemeinsamer Referenzpunkt der Beiträge ist die Frage der Adressierung unter emanzipatorischer Perspektive. Dabei orientieren sich die Darstellungen der Handlungsfelder an der Selbstbestimmung und Teilhabe der Adressatinnen und Adressaten, ohne deren gesellschaftliche und strukturelle Begrenzungen aus dem Blick zu verlieren. In welcher Weise Begründungen und Fragen der Adressierung in den jeweiligen Handlungsfeldern verhandelt werden, beleuchten die einzelnen Beiträge handlungsfeldspezifisch und ermöglichen damit eine neue Betrachtungsweise der vielfältigen Praxiskontexte Sozialer Arbeit. Auf diese Weise entsteht eine besondere Einführung in die Soziale Arbeit: eine umfassende, aktuelle und systematische Darstellung der Handlungsfelder mit Fokus auf das grundlegende emanzipatorische Ziel Sozialer Arbeit, die Förderung von Teilhabe und Selbstbestimmung ihrer Adressatinnen und Adressaten.
Leading edge serrations are well-known for their aeroacoustic potential in reducing aerofoil-turbulence interaction noise and are also associated with certain aerodynamic advantages. To prepare leading edge serrations for industrial application, two obstacles remain to be addressed. First is a combined analysis of the aeroacoustic and the aerodynamic performance of leading edge serrations to develop optimum designs. Second is the need to examine the transferability of the known effects of leading edge serrations from a single aerofoil to full rotors, which are considered to be the final area of application.
This thesis aims to assist in the transfer of a well-investigated aerofoil with serrated leading edges from the rigid to the rotating domain. With this purpose, a single aerofoil type is selected and thoroughly analysed, experimentally and numerically, to generate a reliable data basis for aerodynamic performance and noise reduction capability. Aside from gathering information on the overall performance, the spatial distribution of the noise sources is localised, and the spectral composition of the noise reduction is found to follow a clearly defined scaling law. Aerodynamically, generated vortices are found to be responsible for a complex three-dimensional separation mechanism of the leading edge serrations, causing a delay of stall.
The generated data basis is then used to design low-pressure axial fans of minimum complexity by keeping the initially chosen aerofoil type. The experimentally identified noise reduction mechanisms for the serrated axial fans are found to be more diverse than the single aerofoil and highly dependent on the inflow conditions and the operation point of the fan. A highly similar pattern for the spectral scaling of the noise reduction supports the finding that at optimum operation conditions, the previously identified noise reduction mechanisms for the single aerofoils are transferable to the rotating domain. On the other hand, additional aerodynamic mechanisms are found to dominate the noise reduction for the instability region of the fan, also contributing to reduced blade-to-blade interaction effects. Moreover, the blade-tip leakage flow is altered by delaying the development of coherent structures.
The next step towards a more general description of the aeroacoustic and aerodynamic dependencies is developing a comprehensive model based on artificial neural networks. This model allows a combined analysis of the aerodynamic and acoustic performance of rotors with serrated leading edges and shows an accurate prediction of the overall performance and the spectral composition of the radiated noise. It also enables the development of multi-objective optima for serration designs and motivates further studies into the generalisability of the observed trends. Furthermore, the developed model represents a feasible tool to create tailored serration designs for maximum efficiency in both aeroacoustics and aerodynamics, contributing to the development of future low-noise fans and rotating machinery.

(2018)
Die Buzzwords Agilität und Digitalisierung sind in aller Munde. Durch den damit verbundenen digitalen Wandel benötigt der Arbeitsmarkt Personal mit hoher Digitalkompetenz, und zwar über alle Branchen und Berufsprofile hinweg. Doch wie lässt sich das erreichen? Welchen Part können und sollten Hochschulen in der Entwicklung der digital literacy übernehmen? Anhand konkreter Beispiele aus der Lehrpraxis zeigt der Vortrag auf, wie agile Konzepte und digitale Medien in neuen Lernsettings zusammenwirken können, um die Studierenden besser auf eine zunehmend digitalisierte Lebens- und Arbeitswelt vorzubereiten.
Videomitschnitt der Vorlesung ist verfügbar. Siehe related URL.
Das Buzzword Agilität ist in aller Munde und wird häufig im Zusammenhang mit Projektmanagement oder Softwareentwicklung genannt. Auch die Startup-Szene macht sich agile Konzepte intensiv zu eigen. Aber Agilität in der Hochschullehre? Im Agilen Manifest aus dem Jahre 2001 sind - auch jenseits der Technik - wichtige Werte und Prinzipien, wie z.B. Selbstorganisation, Transparenz, Fokussierung und Kommunikation auf Augenhöhe beschrieben. Im Vortrag wird es darum gehen, ob und wie sich agile Konzepte, Methoden und Werkzeuge auf die Lehre übertragen lassen, um dadurch vielleicht wendiger und individueller auf aktuelle Lernbedarfe reagieren zu können. Darüber hinaus wird anhand konkreter Beispiele aus der Lehrpraxis aufgezeigt, wie der Einsatz digitaler, agiler Werkzeuge Studierende besser auf die sogenannten „21st Century Skills“ vorbereiten und gleichzeitig digital kompetenter machen kann.
Im anschließenden Praxisworkshop mit dem Titel "Digital Learning Blends für agile Lernsettings" werden beispielhaft einige digitale Tools des vorangegangenen Vortrages vorgestellt, die in agilen Lernsettings eine wichtige Rolle einnehmen können.

Alltag und Soziale Arbeit in der Corona-Pandemie. Einblicke in Perspektiven der Adressat*innen
(2022)
Wie ergeht es Menschen in ohnehin schon schwierigen Lebenslagen während der Corona-Krise? Ziel des Sammelbandes ist es, die Perspektive von Adressat*innen und Nutzer*innen Sozialer Arbeit auf die durch die Corona-Krise bedingten Veränderungen ihrer Alltagswelten und die Angebote Sozialer Arbeit empirisch aufzuzeigen. Hierzu werden im Sammelband sowohl erste empirische Analysen dargestellt als auch die vorliegenden Ergebnisse übergreifend auf Theoriedebatten sowie Impulse für Praxis und Forschung Sozialer Arbeit hin diskutiert.
Der gegenwärtigen empirischen Leerstelle bezogen auf die Wahrnehmung der Krise von Adressat*innen und Nutzer*innen Sozialer Arbeit steht aktuell eine weit verbreitete Sorge dem Wohlergehen der Adressat*innen Sozialer Arbeit entgegen. Seit April 2020 gibt es eine Vielzahl an Problemaufrissen, Brandbriefen, problematisierenden Analysen, die die Corona-Krise als Verstärkerin ohnehin bestehender sozialer Ungleichheiten betrachten und je nach Ausrichtung politische Interventionen fordern. Ein Großteil dieser Analysen bezieht sich entweder auf Einschätzungen von Sozialarbeiter*innen oder auf analytische Schlüsse.
Im Vergleich zur Perspektive der Sozialen Arbeit als Profession gibt es dagegen bisher kaum Veröffentlichungen zu der Frage, wie die Adressat*innen und Nutzer*innen Sozialer Arbeit selbst die Corona-Krise betrachten und erleben, die in all ihrer Unterschiedlichkeit doch gemein haben, dass sie zumeist über unterdurchschnittliche soziale, ökonomische und kulturelle Ressourcen verfügen. Als Fachgruppe Adressat*innen, Nutzer*innen und (Nicht)Nutzung Sozialer Arbeit der DGSA fühlen wir uns jedoch genau dieser Perspektive besonders verpflichtet: diejenigen zu Wort kommen zu lassen, ,über die in der Sozialen Arbeit meist nur gesprochen wird
