TY - THES A1 - Büchel, Carolin T1 - Fitnesssport: Gestaltung eines mobilen Outdoor-Trainingssystems N2 - Der Wunsch nach Gesundheit und Individualisierung der eigenen Freizeit als Ausgleich zum Alltag ist heute in der Gesellschaft so ausgeprägt wie noch nie. Dabei sind die positiven Auswirkungen körperlicher Aktivität auf das Immunsystem, die Lebenserwartung und die Leistungsfähigkeit immer bekannter. Diese Abschlussarbeit greift die erkannte Entwicklung und den wachsenden Wunsch der Nutzenden nach individuellem Fitnesstraining im Freien auf. Das entstandene Outdoor-Trainingssystem „TREICK“ ermöglicht ein mobiles, orts- und zeitunabhängiges Training der eigenen Fitness. Durch „TREICK“ kann der Sportler physiologisch sinnvolle Eigengewichtsübungen in einer selbst gewählten Umgebung ausführen, wodurch das Wohlbefinden und damit die Gesundheit gefördert werden kann. Das System kann als Rucksack oder Fahrradtasche transportiert werden, wobei die Trainingsmatte als Verpackung dient.

Simple tags that can be electronically individually activated and deactivated via a DC control voltage were developed and combined to form an MO array field. This HR operates in the entire 2.45 GHz ISM band for transmitting the illumination signal and receives at twice the stimulus frequency and bandwidth centered around 4.9 GHz. This paper presents the development, the basic theory of a HR system for the characterization of objects placed into the propagation path in-between the radar and the reflectors (similar to a free-space measurement with a network analyzer) as well as first measurements performed by the system. Further detailed measurement series will be made available later on to other researchers to develop AI and machine learning based signal processing routines or synthetic aperture radar algorithms for imaging, object recognition, and feature extraction. For this purpose, the necessary information is published in this paper. It is explained in detail why this SIMO-HR can be an attractive solution augmenting or replacing existing systems for radar measurements in production technology for material under test measurements and as a simplified MIMO system. The novel HR transfer function, which is a basis for researchers and developers for material characterization or imaging algorithms, is introduced and metrologically verified in a well traceable coaxial setup.

But, how to find the best fitting RPA product for a specific situation that creates the expected benefits? This question is related to the general area of software evaluation and selection. In the face of more than 75 RPA products currently on the market, guidance considering those specifics is required. Therefore, this chapter proposes a criteria-based selection method specifically for RPA. The method includes a quantitative evaluation of costs and benefits as well as a qualitative utility analysis based on functional criteria. By using the visualization of financial implications (VOFI) method, an application-oriented structure is provided that opposes the total cost of ownership to the time savings times salary (TSTS). For the utility analysis a detailed list of functional criteria for RPA is offered. The whole method is based on a multi-vocal review of scientific and non-scholarly literature including publications by business practitioners, consultants, and vendors. The application of the method is illustrated by a concrete RPA example. The illustrated structures, templates, and criteria can be directly utilized by practitioners in their real-life RPA implementations. In addition, a normative decision process for selecting RPA alternatives is proposed before the chapter closes with a discussion and outlook.

Er erzählt die Geschichte von zwei jungen Männern, welche beide ähnliche Trauer erfahren mussten und sich gegenseitig wieder zurück auf die Beine helfen. Das Ziel dieser Arbeit ist es, ohne Worte und vor allem mit Bildgewalt bestimmte Emotionen zu vermitteln. Der Eigeninhalt der Arbeit umfasst jeden Schritt der Produktion eines animierten Kurzfilms. Dazu gehören Konzeptzeichnungen, Storyboard, Hintergründe, Animation, Cleanup und Vertonung. Besonderes Augenmerk wird bei der Produktion auf die Animation gelegt, insbesondere durch die Komplexität der animierten Charaktere. Letztendlich wird eine herzerwärmende, doch bittersüße und traurige Geschichte erzählt, welche den Zuschauer tief berührt.

Direct structural reliability design by chance con-strained programming is based on the prescribed failure probabilities, which is an effective approach of stochastic programming if it can be formulated as an equivalent deterministic optimization problem. We restrict uncertainty to strength, the loading is still deterministic. A new formulation is derived in case of random strength with lognormal distribution. Upper bound and lower bound shakedown load factors are calculated simultaneously by a dual algorithm.

Such extreme events are rare and full flood protection can never be ensured with reasonable financial means. But still, this event must be starting point to reconsider current design concepts. This article aims at sharing some thoughts on potential hazards, the selection of return periods and remaining risk with the focus on Germany.

Nevertheless, the design of industrial plants is inadequately described in recent codes and guidelines, as they do not consider the dynamic interaction between the structure and the installations and thus the effect of seismic response of the installations on the response of the structure and vice versa. The current code-based approach for the seismic design of industrial facilities is considered not enough for ensure proper safety conditions against exceptional event entailing loss of content and related consequences. Accordingly, SPIF project (Seismic Performance of Multi-Component Systems in Special Risk Industrial Facilities) was proposed within the framework of the European H2020 - SERA funding scheme (Seismology and Earthquake Engineering Research Infrastructure Alliance for Europe). The objective of the SPIF project is the investigation of the seismic behaviour of a representative industrial structure equipped with complex process technology by means of shaking table tests. The test structure is a three-story moment resisting steel frame with vertical and horizontal vessels and cabinets, arranged on the three levels and connected by pipes. The dynamic behaviour of the test structure and of its relative several installations is investigated. Furthermore, both process components and primary structure interactions are considered and analyzed. Several PGA-scaled artificial ground motions are applied to study the seismic response at different levels. After each test, dynamic identification measurements are carried out to characterize the system condition. The contribution presents the experimental setup of the investigated structure and installations, selected measurement data and describes the obtained damage. Furthermore, important findings for the definition of performance limits, the effectiveness of floor response spectra in industrial facilities will be presented and discussed.

Since the middle of the 20th century the behaviour of these non-structural elements under seismic loading has been studied in numerous experimental campaigns. However, most of the studies were carried out by means of in-plane tests, while there is a lack of out-of-plane experimental investigations. In this paper, the out-of-plane tests carried out on full scale masonry infilled frames are described. The results of the out-of-plane tests are presented in terms of force-displacement curves and measured out-of-plane displacements. Finally, the reliability of existing analytical approaches developed to estimate the out-of-plane strength of masonry infills is examined on presented experimental results.
