Bürgerliches Recht
(2022)
Die nun vorliegende vollständig überarbeitete und aktualisierte zehnte Auflage des bewährten Lehrbuches deckt die wesentlichen Inhalte des zivilrechtlichen Lehrstoffes ab. Es werden in kompakter Form der Allgemeine Teil des BGB, das (Allgemeine und Besondere) Schuldrecht sowie das Sachenrecht dargestellt. Vervollständigt wird dieses Buch mit einem abschließenden Kapitel zum Zivilprozessrecht. Geschult werden das Verständnis für die Strukturen und Zusammenhänge im Bürgerlichen Recht und das Verständnis für die Verbindungen mit dem Zivilprozessrecht. Eine Vielzahl von Beispielen aus der Praxis, einprägsame Illustrationen, zahlreiche Schemata und Fälle mit Lösungsvorschlägen ermöglichen damit gleichzeitig auch ein anwendungsorientiertes bzw. fallorientiertes Lernen. Seine inhaltliche Kompaktheit macht es so zu einem idealen studienbegleitenden Lehrbuch für Studierende an Universitäten, Hochschulen, Berufsakademien und anderen Bildungseinrichtungen.
Im Sommersemester 2022 habe ich laufende und neue Forschungsprojekte sowohl national wie auch international vorangetrieben. Schwerpunktmäßig wurde die international etablierte Global Sanctions Data Base (GSDB) in Kooperation mit Forschern aus den USA und Österreich aktualisiert und in Form einer Forschungsarbeit der Forschungsgemeinschaft bekannt gemacht. Aufgrund der erarbeiteten Expertise habe ich zahlreiche Vorträge und Interviews in Medien zu Sanktionen und deren ökonomische Wirkung gegeben. Darüber hinaus wurde ein Buchkapitel zu Sanktionen in Kooperation mit internationalen Wissenschaftlern verfasst. Ferner wurde ein neues Forschungsprojekt in Kooperation mit einem regionalen Unternehmen zur Entwicklung eines Prozesses für die THG-Bilanzierung initiiert. Zwei wissenschaftliche Publikationen (peer-reviewed) wurden finalisiert. Ferner wurden 2 neue wissenschaftliche Forschungsprojekte mit internationalen Wissenschaftlern initiiert und die Ergebnisse in Arbeitspapieren veröffentlicht. Die zugrundeliegenden Manuskripte wurden in peer-reviewed Zeitschriften eingereicht. In Kooperation mit der Universität Konstanz wurde ein Schülertag für Gymnasiasten organisiert, um die Bedeutung von Wirtschaftspolitik den Schülern näher zu bringen.
In many industrial applications a workpiece is continuously fed through a heating zone in order to reach a desired temperature to obtain specific material properties. Many examples of such distributed parameter systems exist in heavy industry and also in furniture production such processes can be found. In this paper, a real-time capable model for a heating process with application to industrial furniture production is modeled. As the model is intended to be used in a Model Predictive Control (MPC) application, the main focus is to achieve minimum computational runtime while maintaining a sufficient amount of accuracy. Thus, the governing Partial Differential Equation (PDE) is discretized using finite differences on a grid, specifically tailored to this application. The grid is optimized to yield acceptable accuracy with a minimum number of grid nodes such that a relatively low order model is obtained. Subsequently, an explicit Runge-Kutta ODE (Ordinary Differential Equation) solver of fourth order is compared to the Crank-Nicolson integration scheme presented in Weiss et al. (2022) in terms of runtime and accuracy. Finally, the unknown thermal parameters of the process are estimated using real-world measurement data that was obtained from an experimental setup. The final model yields acceptable accuracy while at the same time shows promising computation time, which enables its use in an MPC controller.
This paper presents a modeling approach of an industrial heating process where a stripe-shaped workpiece is heated up to a specific temperature by applying hot air through a nozzle. The workpiece is moving through the heating zone and is considered to be of infinite length. The speed of the substrate is varying over time. The derived model is supposed to be computationally cheap to enable its use in a model-based control setting. We start by formulating the governing PDE and the corresponding boundary conditions. The PDE is then discretized on a spatial grid using finite differences and two different integration schemes, explicit and implicit, are derived. The two models are evaluated in terms of computational effort and accuracy. It turns out that the implicit approach is favorable for the regarded process. We optimize the grid of the model to achieve a low number of grid nodes while maintaining a sufficient amount of accuracy. Finally, the thermodynamical parameters are optimized in order to fit the model's output to real-world data that was obtained by experiments.
There have been substantial research efforts for algorithms to improve continuous and automated assessment of various health-related questions in recent years. This paper addresses the deployment gap between those improving algorithms and their usability in care and mobile health applications. In practice, most algorithms require significant and founded technical knowledge to be deployed at home or support healthcare professionals. Therefore, the digital participation of persons in need of health care professionals lacks a usable interface to use the current technological advances. In this paper, we propose applying algorithms taken from research as web-based microservices following the common approach of a RESTful service to bridge the gap and make algorithms accessible to caregivers and patients without technical knowledge and extended hardware capabilities. We address implementation details, interpretation and realization of guidelines, and privacy concerns using our self-implemented example. Also, we address further usability guidelines and our approach to those.
In this letter, we present an approach to building a new generalized multistream spatial modulation system (GMSM), where the information is conveyed by the two active antennas with signal indices and using all possible active antenna combinations. The signal constellations associated with these antennas may have different sizes. In addition, four-dimensional hybrid frequency-phase modulated signals are utilized in GMSM. Examples of GMSM systems are given and computer simulation results are presented for transmission over Rayleigh and deep Nakagami- m flat-fading channels when maximum-likelihood detection is used. The presented results indicate a significant improvement of characteristics compared to the best-known similar systems.
In tomato drying, degradation in final quality may occur based on the drying method used and predrying preparation. Hence, this research was conducted to evaluate the effect of different predrying treatments on physicochemical quality and drying kinetics of twin-layer-solar-tunnel-dried tomato slices. During the experimental work, tomato slices of var. Galilea were used. As predrying treatments, 0.5% calcium chloride (CaCl2), 0.5% ascorbic acid (C6H8O6), 0.5% citric acid (C6H8O7), and 0.5% sodium chloride (NaCl) were used. The tomato samples were sliced to 5 mm thickness, socked in the pretreatments for ten minutes, and dried in a twin layer solar tunnel dryer under the weather conditions of Jimma, Ethiopia. Untreated samples were used as control. The moisture losses from the samples were monitored by weighing samples at 2 h interval from each treatment. SAS statistical software version 9.2 was used for analyzing data on the physicochemical quality of tomato slices in CRD with three replications. From the experimental result, it was observed that dried tomato slices pretreated with 0.5% ascorbic acid gave the best retention of vitamin C and total phenolic content with a high sugar/acid ratio. Better retention of lycopene and fast drying were observed in dried tomato slices pretreated with 0.5% sodium chloride, and pretreating tomatoes with 0.5% citric acid resulted in better color values than the other treatments. Compared to the control, pretreating significantly preserved the overall quality of dried tomato slices and increased the moisture removal rate in the twin layer solar tunnel dryer.
