Achtsamkeit üben
(2018)
Kognitive Verhaltenstherapie (KVT) wird als psychotherapeutisches Verfahren am häufigsten in der Praxis angewendet. In der evangelischen Seelsorgelehre wurde diese Form der Therapie hingegen bislang in ihrer Vielfalt kaum angemessen wahrgenommen. Dem Anspruch der aktuellen Poimenik, verschiedene psychologische und psychotherapeutische Strömungen kritisch zu diskutieren und zu rezipieren, wird mit diesem dialogischen Ansatz Rechnung getragen. Der vorliegende Tagungsband versammelt die Beiträge namhafter Autoren aus den Bereichen der Psychologie, Psychotherapie und Seelsorgelehre. Er trägt damit wesentlich zum Schließen dieser Wahrnehmungs- und Forschungslücke bei. Im Fokus des Bandes stehen dabei die Fragen um Spiritualität und Sinn, die in den Feldern von Seelsorge und Psychotherapie disziplinübergreifend von Bedeutung sind.

This paper describes the modelling, simulation and energy management of a fuel cell hybrid heavy-duty truck. For this purpose, a longitudinal dynamic model of a 26t truck was set up and the load requirement for the drive train was determined based on a driving cycle. To meet this load requirement as efficiently and dynamically as possible three different energy management strategies were implemented, tested and the impact on the overall system was analysed. In addition, the behaviour of the hybrid system with the various energy management strategies with different battery capacity is shown and analysed.
Our current mobility paradigm increasingly faces economic, ecological, and social limits in urban areas. The aim of this paper is to analyse if a fleet of shared autonomous electric vehicles (AEVs) can meet these challenges while satisfying the current requirements of privately-owned internal combustion engine vehicles (ICEVs). Therefore, analytical models have been developed to simulate and investigate the impacts of mobility behaviour in Berlin and Stuttgart (Germany). The collected data were used to calculate the fleet size, the energy consumption, the emission of particulate matter, nitrogen oxides, and the carbon footprint of different shared AEVs in comparison with privately owned ICEVs. The approach shows that the system of a shared AEV fleet could lower externalities (accident avoidance, traffic jams, free spaces, parking costs and lifetime losses) in cities and generate cost benefits for customers.

Advance Care Planning
(2020)
Das internationale Konzept ‚Advance Care Planning (ACP)‘ etabliert sich in Deutschland sukzessive unter dem Begriff der „Gesundheitlichen Versorgungsplanung für die letzte Lebensphase“. Übergeordnetes Ziel von ACP ist es, Menschen die Möglichkeit zu geben, im Rahmen eines begleiteten Gesprächsprozesses zentrale Vorausverfügungen hinsichtlich ihrer gesundheitlichen Versorgung für Phasen der Nichteinwilligungsfähigkeit zu formulieren und durch eine entsprechende strukturelle Einbettung diesen antizipierten Willensäußerungen im Bedarfsfall Geltung zu verschaffen. Ausgehend von der Skizzierung zentraler Eckpunkte und Rahmungen des Konzeptes arbeitet der Beitrag reflexionswürdige ethische Implikationen und daran gebundene moralische Forderungen heraus, denn das Konzept ist äußerst komplex. Diese Ausführungen sind getragen davon, dass eine qualitätsvolle sowie eine ethisch vertretbare Realisierung des Konzeptes, eine qualitätsvolle Begleitung am Lebensende maßgeblich an das Bewusstsein und den Umgang der professionell im Gesundheitswesen tätigen Personen und Berufsgruppen gebunden ist, die moralischen Forderungen und ethischen Implikationen verantwortungsvoll im Blick zu behalten.
Drug-induced liver toxicity is one of the most common reasons for the failure of drugs in clinical trials and frequent withdrawal from the market. Reasons for such failures include the low predictive power of in vivo studies, that is mainly caused by metabolic differences between humans and animals, and intraspecific variances. In addition to factors such as age and genetic background, changes in drug metabolism can also be caused by disease-related changes in the liver. Such metabolic changes have also been observed in clinical settings, for example, in association with a change in liver stiffness, a major characteristic of an altered fibrotic liver. For mimicking these changes in an in vitro model, this study aimed to develop scaffolds that represent the rigidity of healthy and fibrotic liver tissue. We observed that liver cells plated on scaffolds representing the stiffness of healthy livers showed a higher metabolic activity compared to cells plated on stiffer scaffolds. Additionally, we detected a positive effect of a scaffold pre-coated with fetal calf serum (FCS)-containing media. This pre-incubation resulted in increased cell adherence during cell seeding onto the scaffolds. In summary, we developed a scaffold-based 3D model that mimics liver stiffness-dependent changes in drug metabolism that may more easily predict drug interaction in diseased livers.
Electrochemical strain microscopy (ESM) is a powerful atomic force microscopy (AFM) mode for the investigation of ion dynamics and activities in energy storage materials. Here we compare the changes in commercial LiFePO4 cathodes due to ageing and its influence on the measured ESM signal. Additionally, the ESM signal dynamics are analysed to generate characteristic time constants of the diffusion process, induced by a dc-voltage pulse, which changes the ionic concentration in the material volume under the AFM tip. The ageing of the cathode is found to be governed by a decrease of the electrochemical activity and the loss of available lithium for cycling, which can be stored in the cathode.
This paper uses several techniques to monitor the ageing of commercial LiFePO4 cells, which are cycled at 55 °C and −20 °C at various depths of discharge. Ageing at lower depth of discharge leads to higher capacity fading, as compared to higher depth of discharge. The highest capacity fading is observed using 50% depth of discharge for cycling at 55 °C, while the lowest capacity fading is observed for the cells aged at 100% depth of discharge when cycled at −20 °C. Using incremental capacity analysis and differential voltage analysis the capacity fading is monitored and underlying ageing mechanisms are described. The loss of lithium inventory and the loss of active material, especially on the cathode side, are the major degradation mechanisms for the cells. The first incremental capacity analysis peak of the discharge process can be used in our case to predict remaining life and cell capacity.
The paper presents post-mortem analysis of commercial LiFePO4 battery cells, which are aged at 55 °C and − 20 °C using dynamic current profiles and different depth of discharges (DOD). Post-mortem analysis focuses on the structure of the electrodes using atomic force microscopy (AFM) and scanning electron microscopy (SEM) and the chemical composition changes using energy dispersive X-ray spectroscopy (SEM-EDX) and X-ray photoelectron spectroscopy (XPS). The results show that ageing at lower DOD results in higher capacity fading compared to higher DOD cycling. The anode surface aged at 55 °C forms a dense cover on the graphite flakes, while at the anode surface aged at − 20 °C lithium plating and LiF crystals are observed. As expected, Fe dissolution from the cathode and deposition on the anode are observed for the ageing performed at 55 °C, while Fe dissolution and deposition are not observed at − 20 °C. Using atomic force microscopy (AFM), the surface conductivity is examined, which shows only minor degradation for the cathodes aged at − 20 °C. The cathodes aged at 55 °C exhibit micrometer size agglomerates of nanometer particles on the cathode surface. The results indicate that cycling at higher SOC ranges is more detrimental and low temperature cycling mainly affects the anode by the formation of plated Li.
This paper provides an analysis of the trend in autonomous driving traffic and the development of infrastructural support, whereas the requirements on the infrastructural support will be analyzed. Then selected traffic scenes will be implemented in an autonomous driving simulator tool in order to figure out the required parameters to assist the autonomous vehicle from the infrastructure.

Mithilfe des Konzepts der gesundheitlichen Versorgungsplanung – auch als Advance Care Planning (ACP) oder „Behandlung im Voraus planen“ (BVP) bekannt – sollen Behandlungsziele fest gelegt werden, und zwar für den Fall, dass der Betroffene seinen Willen nicht äußern kann. Neben der individuellen Gesprächsbegleitung spielen in diesem Zusammenhang auch Fall- besprechungen eine wichtige Rolle. Diese sind zwar gesetzlich vorgesehen, jedoch fehlt bislang eine einheitliche Struktur, an der sich Fachkräfte in der Praxis orientieren können.

For an efficient operation of a low voltage PMSM an optimized voltage usage is very important. Because of the relation between the low voltage and the high currents in this type of machine, a large voltage reserve is needed to compensate the influence of parameter mismatches and to guarantee a stable current control. As the power is limited by the low voltage in this type of hybrid drive systems, optimizing the voltage usage is also required to maximize the power and the torque availability. This paper describes a closed loop flux control to maximize the voltage usage. The controller feedback is used to estimate and maximize the available torque for each operating point.
In our present paper, we approach the mixed problem with initial and boundary conditions, in the context of thermoelasticity without energy dissipation of bodies with a dipolar structure. Our first result is a reciprocal relation for the mixed problem which is reformulated by including the initial data into the field equations. Then, we deduce a generalization of Gurtin’s variational principle, which covers our generalized theory for bodies with a dipolar structure. It is important to emphasize that both results are obtained in a very general context, namely that of anisotropic and inhomogeneous environments, having a center of symmetry at each point.
In this presentation the actual state of the ongoing investigations of spray painting processes are summarized. Already at the end of the last century, first experimental and numerical work was done aiming to estimate the film thickness distribution and the transfer efficiency of spray painting processes of complex workpieces. First successful numerical simulations basically used the classical Euler-Langrange approach, in case of electrostatically supported atomizers extended by the necessary models for the charging of droplets and the interaction between charged droplets and electrical fields. Measured droplet size distributions and velocities near the atomizers have been applied as inlet conditions for the simulations.
Due to the good mechanical properties, flax fiber-reinforced epoxy composites
are being widely used as a green alternative to glass fiber composites. However,
plant fibers absorb moisture from the environment, being in a higher moisture
uptake as the relative humidity (RH) increases. This absorbed moisture deteriorates the mechanical properties of the composites. In this study, geometric
and displacement potential function (DPF) approaches are used to predict the
mechanical properties of flax fiber-reinforced epoxy composites under environmental conditions, in particular, different RH values. The tensile properties
that were measured experimentally strongly agreed with the analytical findings.
Almost similar results were found for the tensile strain those were measured
experimentally and the one predicted by the geometric function.
However, the predicted strain values were 38% and 42% less than the experimental ones for 0% and 95% RH conditioned composites, respectively, when
DPF was used. Good conformity between the experimental, analytical, and
DPF formulation for predicting mechanical properties ensures the practical
applicability of this study. The formulations established in this work could,
therefore, be utilized to analytically solve laminated composites under specific
boundary conditions in structural applications.
For a low voltage IPMSM used in a hybrid drive system of a consumer car, it is of the highest importance to design a torque controller circuit that produces an accurate torque at the shaft. The accurate torque is needed to distribute the load between the combustion engine, or the manual break, and the electrical drive. As the capacitance of the batteries used in this type of car is usually very small, the control of the batteris state of charge and its output current is quite critical. Therefore, a precise torque control is elementary. Temperature changes have a large impact on the IPMSM internal parameters. Especially the permanent magnet flux and the stator resistance are affected by temperature changes. There are techniques to observe and calculate the temperature variation of these parameters. This contribution describes a method to handle the influence of temperature variation on the actual torque at the shaft, by correcting the current commands of the open loop controller.
Viele Studierende erleben das Lernen auf Klausuren als anstrengend, ermüdend und wenig motivierend. Oftmals liegt das nicht am mangelnden Interesse an dem Thema, sondern entsteht dadurch, dass das Lernen allein und ohne direkte Rückmeldung zum Lernerfolg erfolgt.
Um hier eine neue, motivierendere Möglichkeit des Lernens zu schaffen, wurde von Studierenden der technischen Betriebswirtschaft an der Hochschule Esslingen ein haptisches Planspiel entwickelt - zum Einsatz in der Lehre und insbesondere zur Klausurvorbereitung in Veranstaltungen zum Qualitätsmanagement in Bachelorstudiengängen. Die Spieler müssen dabei im Rahmen vorgegebener Zielkorridore und Budgets qualitätsrelevante Entscheidungen treffen, aber auch mit anderen Unternehmen, die im Wettbewerb zum eigenen Unternehmen stehen, punktuell zusammenarbeiten und auf exogene Einflüsse reagieren. Die gelernte Theorie findet sofort eine praktische Anwendung und durch Diskussion mit den anderen Mitspielern ergibt sich ein unmittelbares Feedback zu den eigenen Antworten im Sinne eines Peer Learnings.
Durch die Reduzierung der Wertschöpfungstiefe in vielen Unternehmen nehmen die Herausforderungen an das Qualitätsmanagement stetig zu. Der Zuwachs an nationalen, aber auch internationalen Lieferanten lässt die Anzahl der Auditierungen zur Qualifizierung und Entwicklung von Lieferanten stetig steigen. In diesem Zusammenhang müssen neue Lösungsansätze entwickelt werden, um die notwendigen Ressourcen optimal zu nutzen und die entstehenden Kosten möglichst gering zu halten.
The derivation and understanding of Partial Differential Equations relies heavily on the fundamental knowledge of the first years of scientific education, i.e., higher mathematics, physics, materials science, applied mechanics, design, and programming skills. Thus, it is a challenging topic for prospective engineers and scientists.
This volume provides a compact overview on the classical Partial Differential Equations of structural members in mechanics. It offers a formal way to uniformly describe these equations. All derivations follow a common approach: the three fundamental equations of continuum mechanics, i.e., the kinematics equation, the constitutive equation, and the equilibrium equation, are combined to construct the partial differential equations.

Bone Cement
(2020)
This book provides an overview of the composition of polymeric and ceramic bone cements. It also discusses complex, biomimetic structures based on biomaterials, such as cells and bioactive molecules, which more closely resemble natural bone
The first chapter describes the main concepts of the cementation process and the parameters affecting it, while the second chapter focuses on the composition and structure of candidate biomaterials. Lastly, the third and fourth chapters present recent research aimed at improving the ability of naked biomaterials to enhance bone healing by adding cells and bioactive agents.
This study aid on numerical optimization techniques is intended for university undergraduate and postgraduate mechanical engineering students. Optimization procedures are becoming more and more important for lightweight design, where weight reduction can, for example in the case of automotive or aerospace industry, lead to lower fuel consumption and a corresponding reduction in operational costs as well as beneficial effects on the environment. Based on the free computer algebra system Maxima, the authors present procedures for numerically solving problems in engineering mathematics as well as applications taken from traditional courses on the strength of materials. The mechanical theories focus on the typical one-dimensional structural elements, i.e., springs, bars, and Euler–Bernoulli beams, in order to reduce the complexity of the numerical framework and limit the resulting design to a low number of variables. The use of a computer algebra system and the incorporated functions, e.g., for derivatives or equation solving, allows a greater focus on the methodology of the optimization methods and not on standard procedures.
The book also provides numerous examples, including some that can be solved using a graphical approach to help readers gain a better understanding of the computer implementation.
A Review on Dental Materials
(2020)
This book discusses the current biomaterials used for dental applications and the basic sciences underpinning their application. The most critical structures in the oral cavity are the teeth, which play a central role in speaking, biting, chewing, tasting and swallowing. Teeth consist of three types of tissue: the cementum, enamel and dentin, with bone and gingival tissue serving as supporting structures. Caries, tooth wear, trauma and mechanical defects can lead to severe facial conditions; however, correcting these defects remains a challenge for scientists and dentists. Presenting insights form a broad range of disciplines, including materials science, biology, physiology and clinical science, this book provides a timely review of the principles, processing and application of dental materials.
Stoff- und Formleichtbau
(2020)
Dieses Lehrbuch stellt die unterschiedlichen Leichtbaukonzepte anhand einfacher eindimensionaler Strukturen in sehr verständlicher Weise dar und ermöglicht einen leichten Einstieg in das Thema. Es werden nachvollziehbare Informationen und Hinweise zur Werkstoffauswahl und geometrischen Gestaltung von Bauteilen gegeben.
Der Grundgedanke dieser Einführung in die Methode der Finiten Elemente wird von dem Konzept getragen, die komplexe Methode nur anhand eindimensionaler Elemente zu erläutern. Somit bleibt die mathematische Beschreibung weitgehend einfach und überschaubar. Das Augenmerk liegt in jedem Kapitel auf der Erläuterung der Methode und deren Verständnis selbst. Der Leser lernt die Annahmen und Ableitungen bei verschiedenen physikalischen Problemstellungen in der Strukturmechanik zu verstehen und Möglichkeiten und Grenzen der Methode der Finiten Elemente kritisch zu beurteilen.
Die Beschränkung auf eindimensionale Elemente ermöglicht somit das methodische Verständnis wichtiger Themenbereiche (z.B. Plastizität oder Verbundwerkstoffe), die einem angehenden Berechnungsingenieur in der Berufspraxis begegnen, jedoch in dieser Form nur selten an Hochschulen behandelt werden. Somit ist ein einfacher Einstieg – auch in weiterführende Anwendungsgebiete – durch das Konzept (a) Einführung in die Grundlagen (b) exakte Ableitung bei Beschränkung auf eindimensionale Elemente (und in vielen Fällen auch auf eindimensionale Probleme) (c) Umfangreiche Beispiele und weiterführende Aufgaben (mit Kurzlösung im Anhang) gewährleistet.
Zur Veranschaulichung wird jedes Kapitel sowohl mit ausführlich durchgerechneten und kommentierten Beispielen als auch mit weiterführenden Aufgaben inklusive Kurzlösungen vertieft.
