In this paper, we will demonstrate how to identify such ellipses as a rhythmical pattern in modern and postmodern free verse poetry by using data from lyrikline which contain the corresponding audio recording of each poem as spoken by the original author. We present a feature engineering approach based on literary analysis as well as a neural networks based approach for the identification of ellipses within the lines of a poem. A contrast class to the ellipsis is defined from poems consisting of complete and correct sentences. The feature-based approach used features derived from a parser such as verb, comma, and sentence ending punctuation. The classifier of neural networks is trained on the line level to integrate the textual information, the spoken recitation, and the pause information between lines, and to integrate information across the lines within the poem. A statistic analysis of poet's gender showed that 65\% of all elliptical poems were written by female poets. The best results, calculated by the weighted F-measure, for the classification of ellipsis with the contrast class is 0.94 with the neural networks based approach. The best results for classification of elliptical lines is 0.62 with the feature-based approach.}, language = {en} } @misc{MeyerSickendiekHusseinBaumann, author = {Meyer-Sickendiek, Burkhard and Hussein, Hussein and Baumann, Timo}, title = {From Fluency To Disfluency: Ranking Prosodic Features Of Poetry By Using Neural Networks}, series = {Proceedings of the International Conference on Digital Humanities (DH 2019), Utrecht, the Netherlands 9-12 July, 2019}, journal = {Proceedings of the International Conference on Digital Humanities (DH 2019), Utrecht, the Netherlands 9-12 July, 2019}, doi = {10.34894/EGZNMI}, language = {en} } @article{KellnerUtz, author = {Kellner, Florian and Utz, Sebastian}, title = {Sustainability in supplier selection and order allocation: Combining integer variables with Markowitz portfolio theory}, series = {Journal of Cleaner Production}, volume = {214}, journal = {Journal of Cleaner Production}, publisher = {Springer Nature}, doi = {10.1016/j.jclepro.2018.12.315}, pages = {462 -- 474}, abstract = {This research presents a decision support methodology for the multi-criteria supplier selection and order allocation problem. The proposed approach supports purchasing managers in assembling mid-term supplier portfolios while making them aware of the trade-offs between the supplier sustainability, the purchasing costs, and the overall supply risk. First, we propose a multi-objective optimization model with three objectives: to maximize the supplier sustainability, to select the supplier portfolio with the lowest purchasing costs, and to minimize the supply risk. Our model extends existing mathematical approaches that follow the portfolio theory fathered by H. Markowitz by integrating the aspect 'risk' into the supplier selection problem. Secondly, since we allow for integer variables in our model—in contrast to the classical Markowitz portfolio theory—we use the ε-constraint method to visualize the efficient surface. The possibility of considering the non-dominated set of supplier portfolios is advantageous for purchasing managers as they gain a picture of the different optimal supplier portfolios and are able to analyze the trade-offs between the different purchasing goals before making a decision. Finally, we illustrate the applicability of the proposed methodology in a real-world supplier selection and order allocation case from the automotive industry. In the example case, we identify 1754 optimal supplier portfolios that may be assembled based on the eight available suppliers. Our analyses show that each optimal portfolio consists of two suppliers, with one specific supplier being included in each portfolio. Furthermore, four suppliers are not part of any optimal solution.}, language = {en} } @article{KellnerSchneiderbauer, author = {Kellner, Florian and Schneiderbauer, Miriam}, title = {Further insights into the allocation of greenhouse gas emissions to shipments in road freight transportation: The pollution routing game}, series = {European Journal of Operational Research}, volume = {278}, journal = {European Journal of Operational Research}, number = {1}, publisher = {Elsevier}, doi = {10.1016/j.ejor.2019.04.007}, pages = {296 -- 313}, abstract = {At present, there is no globally accepted standard for the allocation of greenhouse gas (GHG) emissions to shipments in road freight transportation. The only official international standard for emission calculation of transport operations is the European Norm EN-16258. However, even this norm still allows choosing from several alternative emission allocation schemes. This research aims to harmonize the process of GHG declarations for supply chains by identifying among all allocation units specified by EN-16258 the one that describes a shipment's contribution to GHG emissions best. For this purpose, concepts of the cooperative game theory are used. First, we develop three transport scenarios that allow studying a shipment's effect on GHG: a vehicle routing problem, a network flow model, and a mixed scenario. Our approach extends previous research projects because we take into account that shipment characteristics in terms of origin, destination, weight, and volume consume transport capacities to different degrees, impact the routing of the commercial vehicles and, thus, determine GHG. Second, we present the results of a computational study that bases on the introduced transport scenarios and that compares the allocation vectors resulting from the EN-16258 allocation rules with the Shapley value, which serves as a benchmark for a shipment's contribution to GHG. Furthermore, we show how often the EN-16258 allocation principles are in line with a set of game theoretical fairness criteria. The results indicate that the allocation unit 'distance' is the closest to the game theory benchmark and most often in line with game theoretical fairness criteria.}, language = {en} } @article{KellnerLienlandUtz, author = {Kellner, Florian and Lienland, Bernhard and Utz, Sebastian}, title = {An a posteriori decision support methodology for solving the multi-criteria supplier selection problem}, series = {European Journal of Operational Research}, volume = {272}, journal = {European Journal of Operational Research}, number = {2}, publisher = {Springer}, doi = {10.1016/j.ejor.2018.06.044}, pages = {505 -- 522}, abstract = {This research presents a novel, state-of-the-art methodology for solving a multi-criteria supplier selection problem considering risk and sustainability. It combines multi-objective optimization with the analytic network process to take into account sustainability requirements of a supplier portfolio configuration. To integrate 'risk' into the supplier selection problem, we develop a multi-objective optimization model based on the investment portfolio theory introduced by Markowitz. The proposed model is a non-standard portfolio selection problem with four objectives: (1) minimizing the purchasing costs, (2) selecting the supplier portfolio with the highest logistics service, (3) minimizing the supply risk, and (4) ordering as much as possible from those suppliers with outstanding sustainability performance. The optimization model, which has three linear and one quadratic objective function, is solved by an algorithm that analytically computes a set of efficient solutions and provides graphical decision support through a visualization of the complete and exactly-computed Pareto front (a posteriori approach). The possibility of computing all Pareto-optimal supplier portfolios is beneficial for decision makers as they can compare all optimal solutions at once, identify the trade-offs between the criteria, and study how the different objectives of supplier portfolio configuration may be balanced to finally choose the composition that satisfies the purchasing company's strategy best. The approach has been applied to a real-world supplier portfolio configuration case to demonstrate its applicability and to analyze how the consideration of sustainability requirements may affect the traditional supplier selection and purchasing goals in a real-life setting.}, language = {en} } @incollection{LukeschKellner, author = {Lukesch, Maximilian and Kellner, Florian}, title = {Geoinformationssysteme f{\"u}r Logistikmanager: Eine praxisorientierte Einf{\"u}hrung am Beispiel der Freeware QGIS}, series = {Praxishandbuch Logistik}, booktitle = {Praxishandbuch Logistik}, editor = {Pradel, Uwe-Heiner}, publisher = {Wolters Kluwer}, address = {K{\"o}ln}, language = {de} } @book{KellnerBrabaender, author = {Kellner, Florian and Brab{\"a}nder, Christian}, title = {VBA mit Excel : Einf{\"u}hrung f{\"u}r Betriebswirte}, publisher = {Springer Gabler}, address = {Berlin}, isbn = {9783662597408}, doi = {10.1007/978-3-662-59740-8}, pages = {XI, 149}, abstract = {Dieses Buch bietet eine anwendungsorientierte Einf{\"u}hrung in die Programmierung mit Visual Basic for Applications (VBA) in Microsoft Excel.

The report presents the outcome of an identification and detailing of user acceptance and motivation strategies for the overall system (REACH, Touchpoints \& Engine concept) and subsystems (Touchpoints, REACH toolkit elements), providing full consideration and detailing of ethical, privacy, legal and usability/accessibility aspects. The REACH system incorporates two strands of technological elements; on the one hand, sensing and monitoring elements, and, on the other hand, motivational and physical engagement elements. For both types, user acceptance is critical allowing for a user experience that leads to (intrinsic, extrinsic, etc.) motivation to more physical activity. The remainder of this Deliverable is structured as follows. First, we introduce the REACH-specific interplay of the concept "user acceptance" with the linked concepts "behaviour change/motivation" and "personalization" in the context of (early) physical activation of elderly persons, and outline the related work and activities conducted in REACH (overall and per TP). Second, we present an analysis and structuring of acceptability drivers (ethical, privacy/security, legal, and accessibility considerations) per Touchpoint. From this we developed an integrated view that represents REACH specific know-how about how to use these acceptability drivers to integrate advanced ICT-driven technology for early detection and intervention use cases seamlessly into age inclusive communities. Third, we present our findings in the context of the development of acceptability drivers for the use of sensing and monitoring elements.

This paper provides an overview of different techniques to determine the depth of carbonation in cementitious materials. The easiest and cheapest way is to remove a core or a fragment of concrete cover and spray a colour indicator on the fresh fractured surface (by splitting). Here, 1 \% phenolphthalein in 70 \% ethanol is most widely used. However, this only indicates in which area the concrete has a pH value below 8.2-10, but not the actual carbonation front which is on average about 20 \% higher. Since phenolphthalein is carcinogenic, alternative colour indicators were investigated in the laboratory. 0.5 \% Curcumin showed similar colour change to phenolphthalein. In addition, 0.1 \% thymolphthalein proved to be an alternative. Scattering within one measurement was lower than for phenolphthalein and the results were closer to the carbonation depths determined by different analytical methods (TGA and LA-ICP-MS). Furthermore, the transition pH-value of thymolphthalein is in the area of 9.3-10.5 which is closer to the actual carbonation front, allowing a more accurate assessment of the risk of reinforcement corrosion.}, language = {en} } @inproceedings{HuKaboutehPawlitzaetal., author = {Hu, Rongbo and Kabouteh, Amir and Pawlitza, Katja and G{\"u}ttler, J{\"o}rg and Linner, Thomas and Bock, Thomas}, title = {Developing Personalized Intelligent Interior Units to Promote Activity and Customized Healthcare for Aging Society}, series = {Proceedings of the 36th International Symposium on Automation and Robotics in Construction (ISARC 2019), 21.05.2019-24.05.2019, Banff, Canada}, booktitle = {Proceedings of the 36th International Symposium on Automation and Robotics in Construction (ISARC 2019), 21.05.2019-24.05.2019, Banff, Canada}, editor = {Al-Hussein, Mohamed}, publisher = {The International Association for Automation and Robotics in Construction}, isbn = {978-952-69524-0-6}, doi = {10.22260/ISARC2019/0032}, pages = {234 -- 241}, abstract = {The world's population is aging at an unprecedented pace.

The research project REACH (funded by European Union's Horizon 2020 Research and Innovation Program under grant agreement No. 690425) aims to develop a service system that will turn clinical and care environments into personalized modular sensing, prevention, and intervention systems that encourage the elderly to become healthy through activities (e.g., physical, cognitive, socializing, personalized food, etc.). As a core research partner, the Chair of Building Realization and Robotics at Technical University of Munich developed a series of Personalized Intelligent Interior Units (PI²Us), which are a special type of smart furniture, that materialize the REACH concepts and functionality seamlessly into the different REACH use case settings. Specifically, the design and functions of the PI²Us, which consist of the PI²U-SilverArc, PI²U-MiniArc, PI²U-Bed, and PI²U-iStander, will be described in detail. In addition, a modular apartment integrating all PI²Us and key technologies in REACH is designed and simulated to create a total interior living and care environment for elderly users. Due to its modularity, parts of the apartment can be easily adapted and rapidly deployed in different REACH use case settings in four European countries, which will then help the REACH consortium execute a series of testing activities.

Numerous challenges are facing the construction industry, such as diminishing productivity, unstable quality, increasing demand, as well as population aging and shortage in the local labor market. One possible solution is to identify and deploy the state-of-the-art technologies that could potentially be implemented in the Hong Kong construction industry. Many studies have been documented about the design and development of a specific construction robotic system. However, there is limited literature on how to investigate the implementation and integration of a range of proposed systems in a specific, local context, and to evaluate the process and impact from short-term, mid-term, and long-term perspectives.

In general, the proposed roadmap, which is structured based on the reviews of the current situation in Hong Kong's construction industry, will evaluate short-term and mid-term practical strategies and action plans. Furthermore, it will forecast a long-term perspective, aspirations, and potential business strategy. The activity of road-mapping is extended with the objective to mitigate existing risks and barriers, and to plan ahead.

As a consequence, the irregularities of a rough road profile must be approximated by an appropriate local road plane that serves as an effective road plane in order to calculate the geometric contact point and the corresponding contact velocities. The Pacejka/SWIFT tire model employs a road enveloping model that generates the effective height and slope by elliptical cams. TMeasy just uses four representative road points for that purpose. In addition, TMeasy replaces the geometric contact point by the static contact point and shifts it finally to the dynamic contact point that represents the point where the contact forces are applied. In doing so, a rather sophisticated but still simple contact calculation is possible.

This trend may intensify freeze-thaw attack in future and lead to more internal and/or external damage in concrete structures. This contribution considers the inclusion of real climate conditions in laboratory simulations. Weather data were recorded and compared with depth-resolved measurements of humidity and temperature in concrete samples stored at the median site of an expressway. The strength of attack depends mainly on the amount of damaging freeze-thaw cycles (minimum temperature <-5°C in combination with moisture). In addition, the salt content of the contact water, minimum temperature and thickness of the ice layer on the concrete surface are decisive. Experiments show that internal and to a minor degree also external damage increase due to lower heating rates. The exposure of the sample itself (i.e. compass direction and removal of snow) affects the resulting damage evolution significantly. In order to save resources and enable the production of more sustainable concrete structures, current accelerated tests need to be adapted to real climatic conditions. 1. Introduction Adaptation to climate change and the associated extreme weather events represents a crucial challenge for our society. The durability of concrete, the most frequently used building material, is highly dependent on the local environment of concrete structures. In the case of a freeze-thaw de-icing salt attack, this is given by essentially the number of frost-thaw cycles (FTC) relevant to damage, the minimum temperature, the thickness of the ice layer, the moisture conditions and the concentration of salt. By investigating the interdependencies, the depth of scaling of the concrete surface per winter period can be predicted as a function of parameters accounting for the different effects of the concrete composition (air content, w/b ratio and binder type), curing time, carbonation and the duration and formation of damaging freeze-thaw cycles, [1, 2]. In order to quantify the individual effects and map them in an engineering model, a large number of laboratory tests are necessary. For this purpose, a known freeze-thaw cycle usually has to be modified. While it is already known that the cooling rate [3] and holding time at minimum temperature [4] affect scaling development, we investigated the effect of different heating rates on scaling on freeze-thaw de-icing salt attack.}, language = {en} } @inproceedings{GehlenThiel, author = {Gehlen, Christoph and Thiel, Charlotte}, title = {Specification of building materials for in service durability}, series = {Proceedings ICSBM 2019: 2nd international conference of sustainable building materials, 2019, Eindhoven}, booktitle = {Proceedings ICSBM 2019: 2nd international conference of sustainable building materials, 2019, Eindhoven}, publisher = {Technische Universiteit Eindhoven}, address = {Eindhoven}, isbn = {978-90-386-4898-9}, pages = {31 -- 40}, abstract = {To assess whether a structural element made of a given building material can withstand the expected mechanical load and environmental exposure in service, designers need information on the material resistances and loads as well as the local conditions.

The STCR-TMS is based on established principles from systems engineering and management and STCR-specific activities developed and tested by the authors as standalone elements in previous research work. Findings: The application of the STCR-TMS revealed the practicability of the method and the underlying concepts to provide practical guidance for the development process. Additional findings indicate that the method is sufficiently generic and flexible for application to different types of robots and indifferent world regions. This research has also shown that key activities need to be addressed to increase the practicability of the STCR-TMS. Originality/value:  A unique characteristic of this method is the evolution with each utilization cycle. In addition, individual elements are interchangeable and can be adapted based on external circumstances. These properties allow the TMS to be applied to other fields in construction robotics.

We explored two approaches for the identification of concrete poetry. The first is based on the definition of concrete poetry in literary theory by the extraction of various types of features derived from a parser, such as verb, noun, comma, sentence ending, conjunction, and asemantic material. The second is a neural network-based approach, which is theoretically less informed by human insight, as it does not have access to features established by scholars. This approach used the following inputs: textual information and the spoken recitation of poetic lines as well as information about pauses between lines.

In this article, we show that a rectified version of the correctness-criterion is unsatisfiable and that the concept of drift-out is geometrically and operationally inconclusive. Satisfying the triangle inequality is insufficient to achieve correctness and unnecessary to overcome the drift-out phenomenon. We place the concept of drift-out on a principled basis and show that Fr{\´e}chet means never drift out.

The lack of warping-invariance contributes to the inconsistency mentioned above and to a strange behavior.

Anhand zweier kontrastiver Fallvignetten sollen Erfahrungen aus dem Projekt „Inklusive Methoden" in Bezug auf M{\"o}glichkeiten, Voraussetzungen, Herausforderungen und Grenzen digitaler Befragungen mit Geb{\"a}rdensprachvideos dargestellt und diskutiert werden.}, language = {de} } @article{SchwaegerlWestfechtel, author = {Schw{\"a}gerl, Felix and Westfechtel, Bernhard}, title = {Integrated revision and variation control for evolving model-driven software product lines}, series = {Software and systems modeling}, volume = {18}, journal = {Software and systems modeling}, number = {6}, publisher = {Springer Science and Business Media}, issn = {1619-1366}, doi = {10.1007/s10270-019-00722-3}, pages = {3373 -- 3420}, abstract = {Software engineering projects are faced with abstraction, which is achieved by software models, historical evolution, which is addressed by revision control, and variability, which is managed with the help of software product line engineering. Addressing these phenomena by separate tools ignores obvious overlaps and therefore fails at exploiting synergies between revision and variation control for models. In this article, we present a conceptual framework for integrated revision and variation control of model-driven software projects. The framework reuses the abstractions of revision graphs and feature models and follows an iterative, revision-control-like approach to software product line engineering called product-based product line development. A single version (i.e., a variant of a selected revision) is made available in a workspace, where the user may apply arbitrary modifications. Based on a user-provided specification of the affected variants, the changes are automatically written back to a transparent repository that relies on an internal multi-version storage. The uniform handling of revisions and variants of models is achieved by transparently mapping version concepts to a semantic base layer, which is defined upon propositional logic. At the heart of the conceptual framework is a dynamic filtered editing model, which allows that the versioned artifacts and the feature model co-evolve. We contribute algorithms for checkout and commit, which satisfy a set of consistency constraints referring to variant specifications in an evolving feature model. This article furthermore addresses the orchestration of collaborative development by distributed replication and the well formedness of text and model artifacts to be checked out into the workspace. The Eclipse-based tool SuperMod demonstrates the feasibility of the conceptual framework. It allows the user to reuse arbitrary editing tools for text-based programming and/or Ecore-based modeling languages. An evaluation based on three case studies investigates the properties of SuperMod with a specific focus on filtered editing. The evaluation demonstrates that the dynamic filtered editing model reduces the cognitive complexity and the amount of user interaction necessary for variation control when compared to unfiltered model-driven approaches to software product line engineering.}, language = {en} }
