Yet, data cleansing, preparation, dataset characterization and statistics or metrics computation steps are frequent. These are mostly performed ad hoc, in an explorative manner and mandate low response times. But, such steps are I/O intensive and typically very slow due to low data locality, inadequate interfaces and abstractions along the stack. These typically result in prohibitively expensive scans of the full dataset and transformations on interface boundaries. In this paper, we examine R as analytical tool, managing large persistent datasets in Ceph, a wide-spread cluster file-system. We propose nativeNDP - a framework for Near Data Processing that pushes down primitive R tasks and executes them in-situ, directly within the storage device of a cluster-node. Across a range of data sizes, we show that nativeNDP is more than an order of magnitude faster than other pushdown alternatives.}, language = {en} } @article{Koenig2019, author = {K{\"o}nig, Werner}, title = {Die Umsetzung der Kraft-W{\"a}rme-Kopplung (KWK) in Galvanikunternehmen : Treiber und Hemmnisse aus sozialwissenschaftlicher Sicht}, series = {WOMag : Kompetenz in Werkstoff und funktioneller Oberfl{\"a}che}, journal = {WOMag : Kompetenz in Werkstoff und funktioneller Oberfl{\"a}che}, number = {12}, publisher = {WOTech}, address = {Waldshut-Tiengen}, issn = {2195-5905}, pages = {19 -- 21}, year = {2019}, abstract = {Die F{\"o}rderung der Kraft-W{\"a}rme-Kopplung (KWK) in kleinen und mittleren Unternehmen der Galvanotechnik stellt ein erkl{\"a}rtes Ziel des Landes Baden-W{\"u}rttemberg und des Forschungsprojekts GalvanoFlex_BW dar.

Obverse to the highly automated synthesis tools in the digital domain (coping with the quantitative difficulty of packing more and more components onto a single chip - a desire well known as More Moore), analog layout automation struggles with the many diverse and heavily correlated functional requirements that turn the analog design problem into a More than Moore challenge. Facing this qualitative complexity, seasoned layout engineers rely on their comprehensive expert knowledge to consider all design constraints that uncompromisingly need to be satisfied. This usually involves both formally specified and nonformally communicated pieces of expert knowledge, which entails an explicit and implicit consideration of design constraints, respectively. Existing automation approaches can be basically divided into optimization algorithms (where constraint consideration occurs explicitly) and procedural generators (where constraints can only be taken into account implicitly). As investigated in this thesis, these two automation strategies follow two fundamentally different paradigms denoted as top-down automation and bottom-up automation. The major trait of top-down automation is that it requires a thorough formalization of the problem to enable a self-intelligent solution finding, whereas a bottom-up automatism -controlled by parameters- merely reproduces solutions that have been preconceived by a layout expert in advance. Since the strengths of one paradigm may compensate the weaknesses of the other, it is assumed that a combination of both paradigms -called bottom-up meets top-down- has much more potential to tackle the analog design problem in its entirety than either optimization-based or generator-based approaches alone. Against this background, the thesis at hand presents Self-organized Wiring and Arrangement of Responsive Modules (SWARM), an interdisciplinary methodology addressing the design problem with a decentralized multi-agent system. Its basic principle, similar to the roundup of a sheep herd, is to let responsive mobile layout modules (implemented as context-aware procedural generators) interact with each other inside a user-defined layout zone. Each module is allowed to autonomously move, rotate and deform itself, while a supervising control organ successively tightens the layout zone to steer the interaction towards increasingly compact (and constraint compliant) layout arrangements. Considering various principles of self-organization and incorporating ideas from existing decentralized systems, SWARM is able to evoke the phenomenon of emergence: although each module only has a limited viewpoint and selfishly pursues its personal objectives, remarkable overall solutions can emerge on the global scale. Several examples exhibit this emergent behavior in SWARM, and it is particularly interesting that even optimal solutions can arise from the module interaction. Further examples demonstrate SWARM's suitability for floorplanning purposes and its application to practical place-and-route problems. The latter illustrates how the interacting modules take care of their respective design requirements implicitly (i.e., bottom-up) while simultaneously paying respect to high level constraints (such as the layout outline imposed top-down by the supervising control organ). Experimental results show that SWARM can outperform optimization algorithms and procedural generators both in terms of layout quality and design productivity. From an academic point of view, SWARM's grand achievement is to tap fertile virgin soil for future works on novel bottom-up meets top-down automatisms. These may one day be the key to close the automation gap in analog layout design.}, language = {en} } @inproceedings{VehiContreras2019, author = {Vehi, Josep and Contreras, Iv{\´a}n}, title = {A decision support system for diabetic patients: closing the loop for MDI users}, series = {EMBC Workshop Telemedicine and Telemonitoring in AAL Home Environments : 41st Engineering in Medicine and Biology (EMB) Conference : July 23, 2019 Berlin, Germany : proceedings of EMBC Workshop "Telemedicine and Telemonitoring in AAL Home Environments"}, booktitle = {EMBC Workshop Telemedicine and Telemonitoring in AAL Home Environments : 41st Engineering in Medicine and Biology (EMB) Conference : July 23, 2019 Berlin, Germany : proceedings of EMBC Workshop "Telemedicine and Telemonitoring in AAL Home Environments"}, editor = {Conti, Massimo and Lebedev, Georgy and Mart{\´i}nez Madrid, Natividad}, publisher = {Hochschule Reutlingen}, address = {Reutlingen}, isbn = {978-3-00-063346-1}, doi = {10.34645/opus-2461}, url = {http://nbn-resolving.de/urn:nbn:de:bsz:rt2-opus4-24619}, pages = {29 -- 31}, year = {2019}, abstract = {Type 1 diabetes is a chronic and a life threatening disease: an adjusted treatment and a proper management of the disease are crucial to prevent or delay the complications of diabetes.

Thereby, we show that different modes of coordination in employment are applied in a fluctuating manner that depends on the specific situations.

However, since precise identification of oxide layers by visual inspection is difficult and time consuming due to inhomogeneous colour distribution, a reliable and efficient method for estimating their thickness is needed. In this study, hyperspectral imaging in the visible wavelength range (425-725 nm) is proposed as an in-line inspection method for analysing oxide layers in real-time during processing of copper components such as printed circuit boards in the automotive industry. For implementation in the production line a partial least square regression (PLSR) model was developed with a calibration set of n = 12 with about 13,000 spectra per sample to determine the oxide layer thickness on top of the technical copper surfaces. The model shows a good prediction performance in the range of 0-30 nm compared to Auger electron spectroscopy depth profiles as a reference method. The root mean square error (RMSE) is 1.75 nm for calibration and 2.70 nm for full cross validation. Applied to an external dataset of four new samples with about 13,000 spectra per sample the model provides an RMSE of 1.84 nm for prediction and demonstrates the robustness of the model during real-time processing. The results of this study prove the ability and usefulness of the proposed method to estimate the thickness of oxide layers on technical copper.

Migration was faster in narrow 3 μm-wide channels than in wider 10 μm channels, even in the absence of cell-binding ECM proteins. Cells permeating narrow channels exhibited blebbing and had smooth leading edge profiles, suggesting an ECM-induced transition from mesenchymal invasion to amoeboid invasion. Live cell labeling revealed a mechanosensing period in which the cell attempts mesenchymal-based migration, reorganizes its cytoskeleton, and proceeds using an amoeboid phenotype. Rho/ROCK (amoeboid) and Rac (mesenchymal) pathway inhibition revealed that amoeboid invasion through confined environments relies on both pathways in a time- and ECM dependent manner.

Cryogels were additionally supplemented with different types of proteins, namely collagen (Coll), platelet rich plasma (PRP), immune cells-conditioned medium (CM), and RGD peptides (RGD). The different protein components did not affect scaffolds' porosity or water-uptake capacity, but altered pore size and stiffness.

Ad MSCs were osteogenically differentiated on these scafffolds for 14 days. Cell attachment and survival rates were comparable for all four scaffolds. Runx2 and osteocalcin levels only increased in Ad-MSCs on Coll, PRP and CM cryogels. Osterix levels increased slightly in Ad-MSCs differentiated on Coll and PRP cryogels.

However, using containers leads to a new paradigm for service development and operation: Self service environments enable software developers to deploy and operate container based systems on their own - you build it, you run it. Following this approach, more and more operational aspects are transferred towards the responsibility of software developers. In this work, we propose a concept for self-adaptive cloud services based on container virtualization in line with the microservices architectural style and present a model-based approach that assists software developers in building these services.

We used human primary MAs and human ASCs, differentiated for 14 days, and encapsulated them in collagen type I hydrogels to build up a three-dimensional (3D) adipose tissue model. The maintenance of the models was analyzed after seven days based on a viability staining. Further, the expression of the adipocyte specific protein perilipin A and the release of leptin and glycerol were evaluated. Gene transcription profiles of models based on dASCs and MAs were analyzed with regard to native adipose tissue. Compared to MAs, dASCs showed an immature differentiation state. Further, gene transcription of MAs suggests a behavior closer to native tissue in terms of angiogenesis, which supports MAs as preferred cell type. In contrast to native adipose tissue, genes of de novo lipogenesis and tissue remodeling were upregulated in the in vitro attempts.}, language = {en} } @inproceedings{ThomasDeCarolis2019, author = {Thomas, Bernd and DeCarolis, Joseph}, title = {Evaluation of power-to-X technologies in US energy system futures}, series = {8th Global Conference on Global Warming, April 22-25, 2019 Qatar University and Intercontinental Doha City, Doha, Qatar : conference proceedings}, booktitle = {8th Global Conference on Global Warming, April 22-25, 2019 Qatar University and Intercontinental Doha City, Doha, Qatar : conference proceedings}, editor = {Dincer, Ibrahim}, publisher = {Qatar University}, address = {Doha, Qatar}, isbn = {978-605-66381-7-6}, pages = {320 -- 323}, year = {2019}, abstract = {This paper examines the deployment of Power to-X technologies in the US energy system through 2040. For this analysis, Power-to-X technologies have been added to an input database representing the US energy system as a single region, which is used in conjunction with an energy system optimization model called Tools for energy model optimization and analysis (Temoa). Detailed data for each individual technology, including water electrolysis, hydrogen compression and storage, chemical processing to synthetic natural gas (SNG) and methanol was collected and entered to the input database. Under a deep decarbonization scenario, Power-to-X is deployed beginning in 2035 under the assumption of no new nuclear power plants installed and a restriction on biodiesel production based on limited area for growing crops. The major portion of the hydrogen generated by electrolysis from excess PV- and wind-generated electricity goes into the production of methanol. This result suggests that Power-to-X is used to generate transport fuels in order to reduce CO2 emissions especially in this sector.}, language = {en} } @incollection{MetzgerBollin2019, author = {Metzger, Rolf and Bollin, Ellmar}, title = {Windstrom in der Zimmerdecke : thermoaktive Bauteilsysteme, sogenannte TABS, speichern Energie in Geb{\"a}uden und sorgen f{\"u}r gutes Klima}, series = {Von Br{\"u}cken, Menschen und Systemen : Festschrift f{\"u}r Michael W{\"o}rz}, booktitle = {Von Br{\"u}cken, Menschen und Systemen : Festschrift f{\"u}r Michael W{\"o}rz}, editor = {Banke, Bernd}, publisher = {Hochschule Reutlingen}, address = {Reutlingen}, isbn = {978-3-9821179-1-1}, doi = {10.34645/opus-2352}, url = {http://nbn-resolving.de/urn:nbn:de:bsz:rt2-opus4-23529}, pages = {257 -- 260}, year = {2019}, language = {de} } @incollection{KernKurniawanLahrita2019, author = {Kern, Axel Olaf and Kurniawan, Tonni Agustiono and Lahrita, Lucy}, title = {Municipal solid waste management - using market instruments: applying a co-benefit approach in green economy paradigm for Indonesia}, series = {Von Br{\"u}cken, Menschen und Systemen : Festschrift f{\"u}r Michael W{\"o}rz}, booktitle = {Von Br{\"u}cken, Menschen und Systemen : Festschrift f{\"u}r Michael W{\"o}rz}, editor = {Banke, Bernd}, publisher = {Hochschule Reutlingen}, address = {Reutlingen}, isbn = {978-3-9821179-1-1}, doi = {10.34645/opus-2351}, url = {http://nbn-resolving.de/urn:nbn:de:bsz:rt2-opus4-23518}, pages = {225 -- 255}, year = {2019}, abstract = {In recent years Indonesia has been confronted with an excessive generation of municipal solid waste (MSW), predominantly present in the form of organic refuse. While moving towards integrated solid waste management (ISWM) is an important strategy used to control its generation, it is also now recognized that economic approaches need to be promoted as well in order to tackle the problem concertedly. In this case study, empirical approaches are developed to understand how market instruments could be introduced into environmental services and how to apply co-benefit approach in a green economy paradigm for Indonesia. We investigate the feasibility of introducing market instruments in Indonesia by appliying local co-benefit initiatives adapted from German experiences in integrating market instruments into MSW management practices. Currently co-benefit activities are undertaken in the Sukunan village (Yogjakarta) to promote waste composting using market incentives in the framework of community-based solid waste management (CBSWM). This scheme aims at reducing MSW generation at its source and mobilizing people to be involved in waste separation (organic and non-organic) at household levels. As a result, about 200,000 t of CO2 emissions could be successfully reduced annually. By integrating market instruments into waste management practices, the result of our studies sugggests that Indonesia could make positive changes to its environmental policy and regulation of MSW at local levels.

It focuses on the communication of sustainability aspects and activities of universities. It provides a recommendation, a model for communicating the sustainability activities of universities and emphasises the values of this appraoch. This paper aims to find the most effective ways to convey education for sustainable development to a broad public and initiate communication about sustainability aspects with society. The paper is based on action research done at two universities about the ways in which academic institutions can communicate with their stakeholders in order to report about their own role as a responsible university and also to make an impact on the sustainable development on a local and global scale. Research is focussed on experiences at Universitites of Applied Sciences with their strong focus on applied research, education and transfer. However, these results can be helpful for each academic institution that wants to make a positive impact on society. The concept which we present focusses on the possible impact which universities can generate. Seen as the contribution to the research field of sustainabitliy reporting the paper points out that a continuous qualitative reporting process with a focus on education for SD is an adequate and efficient approach to sustainability reporting for universities and an effective way to reach a broad public. We show that there are several efficient methodss of communication ranging from the traditional sustainability report to publications which address the public and to more innovative methods using the web 2.0. We show and argue that for universities, alternative ways of sustainability communication may be more effective to achieve the sustainability mission. The concept which we present gives the universities a broader impact on society and helps them to support sustainable development in an efficient way.}, language = {en} } @article{MayerGallGutmannTextoretal.2019, author = {Mayer-Gall, Thomas and Gutmann, Jochen and Textor, Torsten and Hugo, Achim and Todt, Katharina and Schmidt, Frank and Weimann, Johannes and K{\"o}nig, Claudia}, title = {Cleanable bag filter : comparisons of different testing methods of ageing of filter materials}, series = {Technical textiles : innovation, technology, application}, volume = {62}, journal = {Technical textiles : innovation, technology, application}, number = {4}, publisher = {IBP, Internat.

Because of large inter-individual variances in the middle ear, especially in wideband tympanometry (WBT), specificity and quantitative evaluation are greatly restricted. A new model-based approach could transform today's predominantly qualitative hearing diganostics into a quantitative and tailored, patient-specific diagnosis, by evaluating WBT measurements with the aid of a middle-ear model. For this particular investigation, a finite element model of a human ear was used. It consisted of an acoustic ear canal and a tympanic cavity model, a middle-ear with detailed nonlinear models of the tympanic membrane and annular ligament, and a simplified inner-ear model. This model has made it possible to identify pathologies from measurements, by analyzing the parameters through senstivity studies and parameter clustering. Uncertainties due to the lack of knowledge, subjectivity in numerical implementation and model simplification are taken into account by the application of fuzzy arithmetic. The most confident parameter set can be determined by applying an inverse fuzzy method on the measurement data. The principle and the benefits of this model-based approach are illustrated by the example of a two-mass oscillator, and also by the simulation of the energy absorbance of an ear with malleus fixation, where the parameter changes that are introduced can be determined quantitatively through the system identification.}, language = {en} } @incollection{Schwarz2019, author = {Schwarz, Sybille}, title = {Die W{\"o}rz´sche Heuristik}, series = {Von Br{\"u}cken, Menschen und Systemen : Festschrift f{\"u}r Michael W{\"o}rz}, booktitle = {Von Br{\"u}cken, Menschen und Systemen : Festschrift f{\"u}r Michael W{\"o}rz}, editor = {Banke, Bernd}, publisher = {Hochschule Reutlingen}, address = {Reutlingen}, isbn = {978-3-9821179-1-1}, doi = {10.34645/opus-2346}, url = {http://nbn-resolving.de/urn:nbn:de:bsz:rt2-opus4-23463}, pages = {97 -- 103}, year = {2019}, language = {de} } @incollection{Eisenbarth2019, author = {Eisenbarth, Peter}, title = {Das Verhalten im Straßenverkehr als Beispiel fehlender Akzeptanz von Normen}, series = {Von Br{\"u}cken, Menschen und Systemen : Festschrift f{\"u}r Michael W{\"o}rz}, booktitle = {Von Br{\"u}cken, Menschen und Systemen : Festschrift f{\"u}r Michael W{\"o}rz}, editor = {Banke, Bernd}, publisher = {Hochschule Reutlingen}, address = {Reutlingen}, isbn = {978-3-9821179-1-1}, url = {http://nbn-resolving.de/urn:nbn:de:bsz:rt2-opus4-23448}, pages = {75 -- 86}, year = {2019}, language = {de} } @incollection{Berendes2019, author = {Berendes, Jochen}, title = {Blinde Flecken.
