This contributes in particular to quantitative studies on reversible language change initiated by G. Altmann by adding explanatory character in tracing global features of general language change back to the individual interaction of speakers. Although the corresponding coupled differential equations are (presumably) non-integrable, we use methods from the theory of dynamical systems to deduce the long-term behaviour (depending on four interaction parameters) of the model for any given initial constellation of speakers. Subsequent numerical analysis of real data on language change is used to justify the relevance of the constructed model for the practicing quantitative linguist. We show how data-fitting methods can be used to determine the four interaction parameters and predict from them the long-term behaviour of the system, i.e. if complete language change or reversible language change will take place.}, language = {en} } @inproceedings{Boehm2022, author = {B{\"o}hm, Stefan-Andreas}, title = {Adaptable Machining Process Identification based on Expert Knowledge and Artificial Intelligence}, series = {Organic Computing Doctoral Dissertation Colloquium 2021}, booktitle = {Organic Computing Doctoral Dissertation Colloquium 2021}, editor = {Tomforde, Sven and Krupitzer, Christian}, publisher = {kassel university press}, address = {Kassel}, doi = {10.17170/kobra-202202215780}, pages = {1 -- 14}, year = {2022}, abstract = {The demand for product individuality increased enormously in recent years and thus affects directly manufacturers and their employees.

Generally, the goal in Cutting and Packing is to assign a set of smaller objects to a set of larger objects. To solve Cutting and Packing problems, practitioners can resort to heuristic and exact methodologies. Lately, machine learning is increasingly used for solving such problems. This paper considers a 2D packing problem from the furniture industry, where a set of wooden workpieces must be assigned to different modules of a trolley in the most space-saving way. We present an experimental setup to compare heuristics, constraint optimization, and deep reinforcement learning for the given problem. The used methodologies and their results get collated in terms of their solution quality and runtime. In the given use case a greedy heuristic produces optimal results and outperforms the other approaches in terms of runtime. Constraint optimization also produces optimal results but requires more time to perform. The deep reinforcement learning approach did not always produce optimal or even feasible solutions. While we assume this could be remedied with more training, considering the good results with the heuristic, deep reinforcement learning seems to be a bad fit for the given use case.}, language = {en} } @unpublished{BoehmZagarRissetal.2024, author = {B{\"o}hm, Stefan-Andreas and Zagar, Bare Luka and Riß, Fabian and Kort{\"u}m, Christian and Knoll, Alois Christian}, title = {Automated Feature Recognition in Surface Cad Models Based on Graph Neural Networks}, doi = {10.2139/ssrn.4772779}, year = {2024}, abstract = {Driven by increasing customer demands, manufacturing processes encompass increasingly intricate workflows.

However, the focus on neoliberal ideologies and educational success has led to significant social implications in the context of social strata. As a result, students now face pressure to perform in the educational system to achieve success and therefore social upward mobility. Families encourage their children to pursue education as a means of social advancement, and this has become a defining feature of Chinese society to have or not have social quality (suzhi). In this presentation, I will discuss how this focus on education impacts the social upward mobility and biographical orientations of elite students in China. I will discuss social mobility and stratification through the lens of habitus theory. According to P. Bourdieu, this theoretical perspective suggests that achievement in the context of social mobility is not solely dependent on economic capital but also on cultural capital. Biographically, this is highly interesting, as families represent the essential point of reference for educational decisions and impact making. Families play a crucial role in shaping educational decisions and aspirations; if individuals lack the necessary economic, social and cultural capital, they may seek opportunities in transnational contexts as a form of outsourcing and even biographical illusion.}, language = {en} } @inproceedings{HerzLorenzMuscatetal.2024, author = {Herz, Jonas and Lorenz, Katharina and Muscat, Dirk and Str{\"u}bbe, Nicole}, title = {Polymeric core-shell and mono-material fibers for concrete reinforcement}, series = {AIP Conference Proceedings}, volume = {3158}, booktitle = {AIP Conference Proceedings}, number = {1}, organization = {38th International Conference of the Polymer Processing Society (PPS-38)}, doi = {10.1063/5.0204946}, year = {2024}, abstract = {A reinforcement of concrete structures is needed because of the low tensile strength of concrete. Corrosion of the usually used steel reinforcments cause issues during time. Therfore, alternative reinforcements produced from non-corosive materials - like polymer fibers - become more interesting. A polymer fiber has to reach high mechanical properties and a good bonding ability to concrete. Both properties can be influenced by the selection of polymer and the used production process. Two polymers, polypropylene and aliphatic polyketone are tested within this study. First mono-material fibers of each material are produced and tested, later the materials are combined in a core-shell fiber. All fibers are produced by standard extrusion or coextrusion and a later drawing process. The mechanical properties are determined by tensile tests. The calculation of interfacial shear strength from single fiber pull-out tests allows an evaluation of the bonding ability. Additionally, fiber surface before and after pull-out is examined using reflected light microscopy. Contact angle measurements are done to evaluate possible influences of the surface energy and polarity. Density measurements are used to compare weight potential of the different mono-material and core-shell fibers. The results show good mechanical properties for all fiber materials. The interfacial shear strength is ≈ 2-3 times higher for fibers with polyketone compared to the ones with polypropylene at the fibers surface, which can be explained by higher surface energy and polarity of the polyketone compared to polypropylene and different surface deformation during pull-out. Lower densities are reached by fibers containing polypropylene.}, language = {en} } @book{HaglKingZentgraf2023, author = {Hagl, Rainer and King, Frank A. and Zentgraf, Peter}, title = {Ingenieurinformatik}, edition = {2}, publisher = {Carl Hanser Verlag GmbH \& Co.

However, microplastic analysis in complex environmental matrices, such as soil samples, remains an analytical challenge. Destructive mass-based methods for microplastic analysis do not determine plastics' shape and size, which are essential parameters for reliable ecological risk assessment. By contrast, nondestructive particle-based methods produce such data but require elaborate, time-consuming sample preparation. Thus, time-efficient and reliable methods for microplastic analysis are needed. The present study explored the potential of frequency-domain fluorescence lifetime imaging microscopy (FD-FLIM) for rapidly and reliably identifying as well as differentiating plastics and natural materials from terrestrial environments. We investigated the fluorescence spectra of ten natural materials from terrestrial environments, tire wear particles, and eleven different transparent plastic granulates <5 mm to determine the optimal excitation wavelength for identification and differentiation via FD-FLIM under laboratory conditions. Our comparison of different excitation wavelengths showed that 445 nm excitation exhibited the highest fluorescence intensities. 445 nm excitation was also superior for identifying plastic types and distinguishing them from natural materials from terrestrial environments with a high probability using FD-FLIM. We could demonstrate that FD-FLIM analysis has the potential to contribute to a streamlined and time-efficient direct analysis of microplastic contamination.

Currently, microplastic samples from environmental matrices can only be identified using time-consuming extraction, sample processing, and analytical methods. Various spectroscopic methods are currently employed, such as micro Fourier-transform infrared, attenuated total reflectance, and micro Raman spectroscopy. However, microplastics in environmental matrices cannot be directly identified using these spectroscopic methods. Investigations using frequency-domain fluorescence lifetime imaging microscopy (FD-FLIM) to identify and differentiate plastics from environmental materials have yielded promising results for directly identifying microplastics in an environmental matrix.

The quality of the final product is significantly influenced by this production step. The manufacturing process step within the edgebanding machine begins with the milling of the raw edge. The quality of the edgebanding process is determined by a large number of process input variables, such as the tool used and the cutting geometry, the type of laminate used for the wood-based material, adhesives, etc. The quality of the edgebanding process is also determined by the type of material processed. Particularly with regard to the materials, the increased use of recycled wood in the particleboard sector and different types of adhesives (with reduced formaldehyde emissions) results in increased demands on the milling process. Due to this developments, most of the earlier investigations (in the years 1990 - 2000) are not comparable with today's general conditions. The mechanical and optical properties of the edge applied to the end product are decisively influenced by the quality of this joint. The milling technology used, as well as the tool used for this purpose and its condition, is a decisive influencing factor in the formation of quality. Tests on the indication of various influencing variables in the edgebanding process at the Rosenheim Technical University of Applied Sciences showed that in the case of chipboard milling, a decrease in the electrical power required for the cutting process can take place with increasing tool wear. It was also demonstrated that previous process steps in furniture production, such as panel dividing by means of sawing or milling/nesting, generally have a significantly different influence on the subsequent joining process during edge banding process. Furthermore, a direct correlation was determined between the mechanical properties of the end product and the condition of the tool used, which can be used as a measurable indicator. In addition to the effect of the tool condition on the mechanical properties of the edge banding, this also has an impact on the optical quality characteristics.

Furthermore, a verification of the defined specification after production is a next step to check the quality and related to the production equipment, to calculate process capability and effectiveness. In 2011, the system of Geometrical Product Specification (GPS) has been published completely. The system is built for a distinct range of geometrical quality characteristics and consists of chains of standards referring to each other. With three elements of these chains, the product can be specified. With three additional elements, the verification of the product and the measuring system is possible. It does not contain the verification of the production processes, the process qualification. The German standard DIN 68100 provides a frame for dimensioning and tolerancing lengths and also angles, parallelism and straightness for furniture components. It includes a method to consider swelling and shrinking of wood and wood-based materials. Apart from its benefit of specifying products in a supply chain, it is rarely used in the branch nowadays. DIN 68100 is currently far away from GPS. To gain all benefits arising from GPS the branch needs a consolidated action. New symbols for drafts and an updated method for tolerancing with moisture consideration have to be developed as well as measuring dimensions of flexible work pieces, like most parts in the furniture industry. In GPS, the link between product verification and process specification is not that consistent. In other branches SPC and methods of process qualifications are established. At the moment the kitchen industry is establishing SPC or similar procedures. An action towards GPS can also accompany these efforts. Due to a shift in the tolerance principles, the GPS system is hardly directly applicable to the furniture industry, e.g. DIN 68100. But there is a real threat that the system is called up accidentally and out of ignorance. This paper sketches a comprehensive system of product specification, verification for furniture components and process qualification. It will share experience gained in the kitchen furniture industry and will add a theoretical analysis of a possible application of GPS-chains for important examples of quality characteristics. The activities are part of a process (VDI 3415-2) carried out in the working group 102 of the Society of German Engineers (VDI).}, language = {en} } @inproceedings{BoehmKortuem2023, author = {B{\"o}hm, Stefan-Andreas and Kort{\"u}m, Christian}, title = {Machining Feature Recognition in Furniture Parts based on a Graph Neural Network}, series = {Proceedings of the 25th International Wood Machining Seminar}, booktitle = {Proceedings of the 25th International Wood Machining Seminar}, editor = {Schajer, Gary}, pages = {8}, year = {2023}, abstract = {Due to the increasing customer demands, companies face the challenge of adapting their manufacturing facilities to produce batch size one parts. In this context, each component comes with specific customer requirements, significantly increasing the complexity of its manufacturing process. Traditional process planning done by employees is no longer feasible in the face of the growing complexity and diversity of batch size one parts. Therefore, there is a need for novel computer-aided process planning methods capable of autonomously learning and identifying the necessary machining features of these parts. We propose a configurable automated feature recognition framework tailored to batch size one parts to address this need. This framework comprises two main components. First, a customizable data generator is developed to create a dataset of computer-aided design models incorporating user-specific machining features. Second, a graph neural network is employed to learn these user-specific machining features by leveraging the graph structure represented by the vertices and edges in each computer-aided design model. We evaluate the effectiveness of our framework using a real-world example from the furniture industry. Specifically, we construct a dataset comprising over 7000 computer-aided design models of wooden boards using our framework's data generator. Each wooden board contains up to 30 randomly placed machining features for the application of connectors and fittings, randomly selected from 14 standard machining features commonly used in the furniture industry. An optimization algorithm adapts a graph neural network for classifying these specific machining features. The results demonstrate that our framework addresses the automated feature recognition problem without requiring data conversions, such as pixels or voxels, as other approaches often do. By introducing this configurable automated feature recognition framework, we solve the challenges posed by batch size one manufacturing. The framework's effectiveness and accuracy are demonstrated through extensive testing on the example of the furniture industry, showcasing its potential for enhancing manufacturing processes in various domains}, language = {en} } @inproceedings{KortuemBoehm2023, author = {Kort{\"u}m, Christian and B{\"o}hm, Stefan-Andreas}, title = {Holistic approach for geometric and technological similarity search in the production for profiled elements in the wood working industry for a more efficient production}, series = {Proceedings of the 25th International Wood Machining Seminar}, booktitle = {Proceedings of the 25th International Wood Machining Seminar}, editor = {Schajer, Gary}, pages = {9}, year = {2023}, abstract = {In the whole field of woodworking, from carpentry to industry, new products are created and designed every day and manufacturers wonder if similar workpieces have already been produced in the company and if corresponding drawings, information, tools, jigs, etc. can be reused. Under certain circumstances, considerable duplication of work can be avoided and a more efficient production is possible. In order to find similar workpieces, it must be clarified what exactly is meant by similarity. The different fields of knowledge do not provide a clear definition. However, similarities are always used to compare objects. In woodworking, objects can be a wide variety of components and products, such as carcase sides, furniture fronts, fittings, tools or profile strips. The search for similar profiled elements - related to the potential, data structure and algorithms - is the focus of this paper. There is a wide range of different profiled elements, which are used constructively as well as decoratively, e.g. for baseboards, door frames, window frames or decorative moulding profiles. These profiles are manufactured in a multi-stage production process in which the workpieces are first machined with profiled tools before surface finishing takes place. Along this production chain, tools, machine settings and, in some cases, fixtures are used that are adapted to the respective profile and can be reused for the same or similar jobs. Inheritance of information offers the greatest potential of similarity search. Inheritance means that existing knowledge in the form of drawings, CNC programs, process parameters and setup specifications, etc., is transferred from existing profiles to a new profile. By inheriting existing information, for example, the effort required for process setting can be reduced by adopting spindle positions, positions of guides and stops, or feed and cutting speeds. However, this can only be done if the process knowledge and other technological information concerning a profile are sufficiently documented. This is the only way how all information is made available for the similarity search and inheritance, and also for setting the processes when the profile is manufactured once again. The profile data must therefore be stored in a meaningful structure without loss of information. Therefore, a holistic product data model was developed that combines the geometrical with the technological profile data. The developed model allows a combined search for geometrically and e.g. materially similar products - also with a weighted evaluation of the individual criteria. The research has shown that data modelling is the essential foundation for the implementation of modern AI algorithms to enable similarity search. In conclusion, the use of a search system for geometrically and technologically similar profiles represents a real innovation for wood processing companies.

Additionally, the research also reveals weaknesses, particularly in managing environmental risks, which the LkSG does not adequately cover. Our findings show that in the short- and medium-term, the LkSG has no potential effects on smallholder cocoa farmers. Furthermore, the potential positive impacts of the law on smallholder cocoa farmers will take a long time to realize, as the LkSG considers primarily tier-1 suppliers.

The δ18O values on iron oxides from BIF and different paragenetic stages of enrichment display a consistent decrease from unenriched BIF (4-9 per mille) to as low as -10 per mille for high-grade iron ore. This large shift in oxygen isotope values is interpreted as evidence for enormous incursion of 'ancient' meteoric water into fault and fracture zones at the time of iron enrichment during the Archean and Paleoproterozoic time. The δ18Ofluid values of paragenetically early iron oxides of > 4 per mille suggest the involvement of magmatic fluids in greenstone belt-hosted Caraj{\´a}s-type iron ore deposits, and basinal brines in basin-hosted Hamersley-type deposits. In contrast, the paragenetically late stage iron oxides in the metamorphosed, basin hosted iron ore deposits of the Quadril{\´a}tero Ferr{\´i}fero display δ18Ofluid values > 6 per mille. This reflects the renewed deep crustal, hypogene (metamorphic or magmatic) fluid influx. Carbon and oxygen isotope data on carbonates in BIF and hydrothermally altered iron ore indicate that carbon in the latter is not derived from BIF units, but represents either magmatic carbon in the case of the Caraj{\´a}s-type deposits or carbon within the underlying basin stratigraphy as in the case of the Hamersley-type iron deposits. The systematic decrease of δ18O values in iron oxides from the early to late paragenetic stages and from the distal to proximal alteration zone, including the ore zone, may be used as a geochemical vector. In this case, oxygen isotope analyses on iron oxides provide a potential exploration tool, particularly for targeting the extension of iron ore bodies or entirely concealed high-grade iron ore deposits, in which hematite/magnetite are frequently the only mineral that can be readily analysed.}, language = {en} } @article{RosiereSantosSilveiraBragaetal.2021, author = {Rosi{\`e}re, C.

Monazite from the iron-oxide veins yielded a SHRIMP 232Th/208Pb date corresponding to fluid circulation coeval with the migmatization of the Archean tonalite-trondhjemite-granodiorite crust. During the Ediacaran to Cambrian Brasiliano orogeny, when the S{\~a}o Francisco craton was consolidated in its present configuration, hydrothermal fluids repeatedly mineralized the Cau{\^e} IF and the younger IFs of the lower Espinha{\c{c}}o Supergroup. Far-field hydrothermal alteration associated with distinct Fe mineralization episodes widely affected Meso- to Neoproterozoic sequences as well as Archean to Paleoproterozoic terranes of the cratonic core. Circulation of hydrothermal fluids during the Brasiliano orogeny caused desilicification, iron mobilization, and widespread alteration of the rocks. The alteration events are dated with monazite and xenotime intergrown with hematite, anatase, and recrystallized rims of detrital zircons from interlayered quartzites and of igneous zircons from pegmatites, granites, acidic volcanic rocks, and orthogneisses, yielding U-Pb dates between 542 and 493 Ma. U-Pb dates point to five Cambrian hydrothermal events from the waning stages to the aftermath of the Brasiliano orogeny.

About 3 million charging events from different European countries were classified according to five different pricing models (cost-free, flat-rate, time-based, energy-based, and mixed) and evaluated using various performance indicators such as connection duration; transferred energy volumes; average power; achievable revenue; and the share of charging and idle time for AC, DC, and HPC charging infrastructure. The study results show that the performance indicators differed for the classified pricing models. In addition to the quantitative comparison of the performance indicators, a Kruskal-Wallis one-way analysis of variance and a pairwise comparison using the Mann-Whitney-U test were used to show that the data distributions of the defined pricing models were statistically significantly different. The results are discussed from various perspectives on the efficient design of public charging infrastructure. The results show that time-based pricing models can improve the availability of public charging infrastructure, as the connection duration per charging event can be roughly halved compared to other pricing models. Flat-rate pricing models and AC charging infrastructure can support the temporal shift of charging events, such as shifting demand peaks, as charging events usually have several hours of idle time per charging process. By quantifying various performance indicators for different charging technologies and pricing models, the study is relevant for stakeholders involved in the development and operation of public charging infrastructure.}, language = {en} } @article{SchmiedtWeiss2024, author = {Schmiedt, Anja Bettina and Weiß, Christian}, title = {The pair correlation function of multi-dimensional low-discrepancy sequences with small stochastic error terms}, series = {Journal of Number Theory}, volume = {259}, journal = {Journal of Number Theory}, doi = {10.1016/j.jnt.2023.12.011}, pages = {422 -- 437}, year = {2024}, abstract = {In any dimension d≥2, there is no known example of a low-discrepancy sequence which possesses Poisssonian pair correlations.

The children were asked to memorize the locations of the objects that differed across the four arrays. Following presentation of each of the first three arrays, memory for the object locations of the respective array was tested (testing condition) or the array was re-presented for additional study (restudy condition). Results revealed that testing Arrays 1 to 3 enhanced children's object location memory for Array 4 relative to restudying. Moreover, children in the testing condition were less likely to confuse Array 4 locations with previous locations, suggesting that testing reduces the buildup of proactive interference. Both effects were found regardless of age.

In the case of Syrians in Brazil who have fled from the civil war, these processes are reflected in transnational family structures, transgenerational mandates, and knowledge transmission. In the case of domestic migration within China, the "mission" that families give their children is social advancement through education (e.g., Crabb 2010; Fong 2004).

In der S3-DEGAM-Leitlinie „Akuter Schwindel in der Hausarztpraxis" werden Empfehlungen f{\"u}r Physiotherapie bei bestimmten Schwindeldiagnosen gegeben. Ob haus{\"a}rztliche Physiotherapieverordnungen den Empfehlungen der Leitlinie entsprechen, ist nicht bekannt.

Methode Die Sekund{\"a}ranalyse beruht auf Daten der Kohortenstudie MobilE-TRA, in der Patient*innen ab 65 Jahren mit S/G in 17 Hausarztpraxen in Bayern und Sachsen befragt wurden. Die Datenerhebung fand von 09/2017-10/2019 statt. Die haus{\"a}rztliche Verordnung und patientenseitige Inanspruchnahme von Physiotherapie wurden mittels validierten sowie selbstentwickelten Frageb{\"o}gen erhoben. Die Daten wurden deskriptiv (Mittelwerte, H{\"a}ufigkeiten) und Verteilungsunterschiede mittels exaktem Test nach Fisher analysiert. Ergebnisse Die Stichprobe umfasste 158 Patient*innen mit S/G. 16 \% der Patient*innen hatten aufgrund von S/G Physiotherapie verordnet bekommen. Dabei entsprachen 14,2 \% der Physiotherapieverordnungen den Empfehlungen der S3-DEGAM-Leitlinie. 32 \% (Bayern 53,8 \%; Sachsen 8,3 \%) der Patient*innen hatten die Physiotherapie nicht in Anspruch genommen. Dabei lag ein signifikanter regionaler Verteilungsunterschied (p = 0,030; Phi = 0,487 [95 \% KI = 0,129-0,846]) vor. Schlussfolgerung Mit 16 \% ist die H{\"a}ufigkeit haus{\"a}rztlicher Physiotherapieverordnungen bei S/G in der Altersgruppe der {\"u}ber 65-J{\"a}hrigen vergleichsweise hoch.

Klar strukturierte und evidenzbasierte Schulungen f{\"u}r die differentialdiagnostische Herangehensweise k{\"o}nnen den Clinical-Reasoning-Prozess und die Therapie von SG verbessern. Eine entsprechende evidenzbasierte Schulung wurde in einem Interventionszweig der multizentrischen Cluster-RCT MobilE-PHY2 begleitend zu einem Decision Tree (DT) f{\"u}r den Clinical-Reasoning-Prozess in der Physiotherapie konzipiert und durchgef{\"u}hrt. Methodik Die Schulung wurde aus den Ergebnissen der Pilotstudie (MobilE-PHY1) und deren Prozessevaluation sowie auf der Grundlage einer dreit{\"a}gigen Fortbildung von und mit einem Schwindelexperten entwickelt. Inhalte waren die Anwendung des DT, theoretische Grundlagen {\"u}ber Schwindel sowie praktische {\"U}bungsanteile. Bei der eint{\"a}gigen Schulung konnten die Physiotherapeut*innen entweder online oder in Pr{\"a}senz teilnehmen.

First results of the mixed-methods process evaluation}, series = {7. Forschungssymposium Physiotherapie}, booktitle = {7. Forschungssymposium Physiotherapie}, year = {2023}, abstract = {BACKGROUND Vertigo, dizziness or balance disorders (VDB) affect the mobility and participation of many older people and are also one of the most frequent reasons for visiting the general practitioner's (GP) practice due to multifactorial causes. Physiotherapy (PT) can be crucial for the complex care of people with VDB but is rarely prescribed by GPs. So we developed an evidence-based, multidisciplinary care pathway as a complex intervention following the UK Medical Research Council guideline, which was piloted and is now being evaluated for effectiveness, accompanied by a process evaluation. METHOD The care pathway of the multicentre cluster-RCT (MobilE-PHY2) included decision aids and training for PTs and GPs in the intervention group and optimised standard care in the control group. A mixed-methods process evaluation following Grant's framework for designing process evaluations examined barriers, facilitating factors and mechanisms of impact in recruiting and reaching participants, implementing the intervention and the response of all participants. Therefore, a logic model was developed illustrating the relationship between the planned work to implement the intervention, the expected mechanism of impact (based on the behaviour change wheel as a change theory), the intended results (output, outcome and impact), and categories of possible influencing factors. The underlying assumption is that a behavioural change in PT and GP is a prerequisite for a change in patient behaviour, which can lead to improved mobility and participation (outcome of MobilE-PHY2). Guided interviews were conducted with patients before the intervention and after six months and with PTs and GPs after six months. Additionally, the training evaluations, completed decision aids and structural questionnaires will be analysed from June 2023. RESULTS AND CONCLUSION At one study site, a total of 37 patients, 17 PTs and nine GPs were included. Interviews were conducted with 16 patients, six PTs and GPs. In the intervention group, 12 PTs and 18 GPs completed decision aids, 13 PTs and two GPs completed evaluation forms, and eight PTs and four GPs completed structural data. The preliminary results of the process evaluation will be reported at the Congress. The results are intended to give indications for a broad implementation of the care pathway, including and promoting physiotherapy and therefore contributing to improved evidence-based healthcare for older people with VDB.}, language = {en} } @article{BotzumNeumaier2023, author = {Botzum, Edeltraud and Neumaier, Stefanie}, title = {K{\"u}nstliche Intelligenz und digitale Transformationsprozesse in der Lehre Sozialer Arbeit}, series = {Jugendhilfe}, volume = {61}, journal = {Jugendhilfe}, number = {5}, publisher = {Luchterhand}, address = {K{\"o}ln}, pages = {388 -- 394}, year = {2023}, language = {de} } @misc{KardasNickLueftl2023, author = {Kardas, Leopold and Nick, Carola and L{\"u}ftl, Katharina}, title = {Technische Hilfsmittel und Assistenzsysteme f{\"u}r ein selbstbestimmtes Leben im Alter: „Demokoffer" f{\"u}r die Wohn- und Technikberatung.

B. Flachs, Hanf und Kenaf) seit langem in der Au-tomobilindustrie eingesetzt. Holzfasern (z. B. Fichte) wurden in diesem Zusammenhang bisher nicht untersucht. Die mechanischen Eigenschaften von Holzfasern sind vergleichbar mit Naturfa-sern. Dar{\"u}ber hinaus bieten Holzfasern Vorz{\"u}ge wie lokale Verf{\"u}gbarkeit und eine vorteilhafte {\"O}kobilanz. Bei Hybridverbunden kann zudem die gleiche Holzfaser sowohl im Anspritzmaterial als auch in fl{\"a}chigen Halbzeugen als Verst{\"a}rkungsfaser genutzt werden. So wird ein unn{\"o}tiger Materialmix vermieden. Im Rahmen dieser Arbeit werden thermoplastische Faserverbundkunststoffe mit Holzfasern un-tersucht. Hierzu werden Fichtefasern {\"u}ber ein thermo-mechanisches Aufschlussverfahren im La-bormaßstab hergestellt. Diese Fichtefasern werden einerseits {\"u}ber einen Spritzgusscompounder mit Polypropylen und Haftvermittler direkt compoundiert, andererseits werden sie mit Polypro-pylenfasern {\"u}ber ein Airlay-Verfahren zu einem Vlies gelegt. Bei der direkten einstufigen Com-poundierung werden verschiedene Holzfaseranteile von bis zu 30 Gew.-\% untersucht. Mit einem steigenden Holzfaseranteil wurde eine Erh{\"o}hung der Zugeigenschaften, der Viskosit{\"a}t und der Dichte festgestellt. Die Holzfasern haben somit eine Verst{\"a}rkungswirkung. Die Kerbschlagz{\"a}hig-keit bleibt bei steigendem Holzfaseranteil im Rahmen der Standardabweichung konstant, ist je-doch im Vergleich zum unver{\"a}nderten Grundpolymer geringer. Eine charakteristische Eigenschaft von direkt angespritzten Strukturen bei Hybridverbunden ist die Verbundhaftung. Im Rahmen dieser Arbeit wird die Verbundfestigkeit von angespritzten Rip-pen aus Polypropylen und Fichtefasern mit verschiedenen Vliesstoffen verglichen. Die Vliese be-stehen aus Holzfasern (Fichte) oder alternativ aus Naturfasern (Kenaf und Hanf), jeweils mit einer Polypropylenmatrix. Im Kopf-Zug-Versuch zeigt sich, dass die Kerntemperatur der Vliese und die Rippengeometrie einen signifikanten Einfluss auf die Verbundhaftung haben.

Im Bereich des Spritzgusswerkzeugs k{\"o}nnen aufgrund des relativ hohen Temperaturunterschieds zur Reinraumluft Kamineffekte auftreten, die der Reinraumstr{\"o}mung entgegen wirken. Im Folgenden wird deshalb der thermische Einfluss eines Spritzgusswerkzeugs exemplarisch bei unterschiedlichen Temperaturen untersucht. Dazu werden Str{\"o}mungsvisualisierungen mittels Nebel und Schlierenfotografie sowie Str{\"o}mungssimulationen genutzt. Bereits relativ niedrige Werkzeugtemperaturen von 40 °C reichten aus, um einen Kamineffekt im Werkzeugbereich entstehen zu lassen, der die Reinraumstr{\"o}mung ung{\"u}nstig beeinflusst.

The results of the study can be used by decision makers to better understand the usage behavior of public charging infrastructure and to align the provision of charging infrastructure with the behavior of users. The user behavior is analyzed using charging areas and scenario-based analysis of charging sessions. More than 300,000 charging sessions at AC and DC charging stations in the urban area of Munich in 2020 were recorded as the data basis for the study. The methodology takes the available vehicle models in the study area as well as the characteristic charging behavior of plug-in electric vehicles (PEV) with a decreasing charging power at high states of charge of the battery into account. The results show a high proportion of idle time at AC charging stations. The outcome of a correlation analysis additionally indicates a correlation between the share of idle time and the proportion of high-density urban living in the survey area.}, language = {en} }
