The goal of technology assessment (TA) is to lend support to society and policy making by promoting understanding of the problems related to the grand sociotechnical challenges of our time, as well as to assess the available options for managing them. Researchers from Japan and Europe reflected together in this book on country-specific developments to identify the conditions that must be present to anchor TA in science, politics, and society. This book helps us to learn about different cultures.

Currently, companies have covered their business processes with stationary workstations while mobile business applications have limited relevance. Companies can cover their overall business processes more time-efficiently and cost-effectively when they integrate mobile users in workflows using mobile device features. The objective is a framework that can be used to model and control business applications for PLM processes using mobile device features to allow a totally new user experience.

Dual-phase steels exhibit good mechanical properties due to a microstructure of strong martensitic inclusions embedded in a ductile ferritic matrix. This work presents a two-scale model for the underlying work-hardening effects; such as the distinctly different hardening rates observed for high-strength dual-phase steels. The model is based on geometrically necessary dislocations and comprises the average microstructural morphology as well as a direct interaction between the constituents.

Durch die aktuellen Entwicklungen des Nachhaltigen Bauens werden, unter Berücksichtigung ökonomischer, ökologischer und soziokultureller Aspekte, zunehmend tiefere Betrachtungsebenen mit ihren jeweiligen Bauteilen berücksichtigt. Aufzugsanlagen, als Teil der technischen Gebäudeausstattung, werden bislang nur in Teilbereichen von dieser Entwicklung erfasst. Die vorliegende Arbeit analysiert den derzeitigen Planungsumfang und entwickelt Hilfsmittel für vernachlässigte Teilbereiche. Sustainability represents a key factor in the construction and real estate sector by optimizing economical, ecological and social aspects of buildings. Transportation systems in buildings, as part of the technical building equipment, are not yet fully integrated into this concept. This work analyses the current approach of lift planning and design and develops supportive tools for neglected sections.

Diese Arbeit zeigt eine systematische Methodik zur effizienten und homogenen Mischung des Strahlungsflusses verschiedenfarbiger Licht emittierender Dioden, kurz LEDs, in Orts- und Winkelraum. Im Mittelpunkt steht hierbei die Anwendung der Geometrien chaotischer Billardsysteme auf den Querschnitt eines Lichtleiters. Als chaotische Lichtleiter ermöglichen sie nach den Prinzipien des deterministischen Chaos eine vollständige Farbmischung. This book describes a systematical method to efficiently and homogeneously mix rays of different coloured Light Emitting Diodes (LEDs) in both the angular and spatial domain. The focus of this work is the application of chaotic billiard geometries on the cross section of a light guide. Such a chaotic light guide offers the possibility to achieve complete colour mixing according to deterministic chaos theory.

A translation surface is a two-dimensional manifold, equipped with a translation structure. It can be obtained by considering Euclidean polygons and identifying their edges via translations. The vertices of the polygons form singularities if the translation structure can not be extended to them. We study translation surfaces with wild singularities, regarding the topology (genus and space of ends), the geometry (behavior of the singularities), and how the topology and the geometry are related.

In der vorliegenden Arbeit wurde eine generelle Methode für die Wiedergabe zweiphasiger Strömungen einer gängigen detaillierten CFD auf einem groben Gitter entwickelt. Die für wenige Teilgeometrien und Strömungsparameter mit repräsentativem Charakter entwickelten numerischen Modelle ermöglichen eine geschlossene Beschreibung für die dazugehörigen Großkomponenten und damit eine umfassende dreidimensionale Strömungssimulation in für industrielle Anwendungen vertretbarer Berechnungsdauer. In this work a general method for reproduction of two-phase flow fields calculated by generic detailed CFD-simulations on a coarse grid is developed. Numerical models for only few sections of geometry and sets of flow parameters with respectively representative character allow a complete description of the large component considered. Thus a comprehensive three-dimensional CFD-simulation, meeting industrial needs for low computational costs, is generated.

''Shared Grasping'' describes a new approach to shared autonomy for grasping and manipulation tasks to be used in a telepresence system. It is realized with two assistance functionalities, which simplify the grasping, and a user interface, which merges haptic feedback and visual assistance. User studies confirm a reduction in operator workload and an increase in task performance while maintaining a high immersion of the operator into the remote environment when using the assistance functions.
