Automobile premium brands operate globally, which is undoubtedly required, because, for the most part, domestic markets are either decreasing or stagnating. China has become today the most important and biggest car market. Recently selling has become challenging because urban areas are well penetrated, and in poorly penetrated rural areas, incomes are low. This is particularly alarming for German brands, because of their premium orientation. Simultaneously, the after-sales market in China has been growing continuously. As a result, this market has a huge potential, which is likewise attractive because it has been scientifically proven across industries that after-sales services are high-margin profit drivers. Despite its great significance, the Chinese automobile after-sales market remains insufficiently researched, especially in terms of critical success factors and cultural influences, which therefore was the starting point for a study. The results will presented and interpreted now in this new working-paper.
High mobility, electrolyte-gated transistors (EGTs) show high DC performance at low voltages (< 2 V). To model those EGTs, we have used different models for the below and the above threshold regime with appropriate interpolation to ensure continuity and smoothness over all regimes. This empirical model matches very well with our measured results obtained by the electrical characterization of EGTs.
Today the methods of numerical simulation of sheet metal forming offer a great diversity of possibilities for optimization in product development and in process design. However, the results from simulation are only available as virtual models. Because there are any forming tools available during the early stages of product development, physical models that could serve to represent the virtual results are therefore lacking. Physical 3D-models can be created using 3D-printing and serve as an illustration and present a better understanding of the simulation results. In this way, the results from the simulation can be made more “comprehensible” within a development team. This paper presents the possibilities of 3D-colour printing with particular consideration of the requirements regarding the implementation of sheet metal forming simulation. Using concrete examples of sheet metal forming, the manufacturing of 3D colour models will be expounded upon on the basis of simulation results.
Die Vision vom "Internet der Dinge" prägt seit Jahren Forschung und Entwicklung, wenn es um smarte Technologien und die Vernetzung von Geräten geht. In der Zukunft wird die reale Welt zunehmend mit dem Internet verknüpft, wodurch zahlreiche Gegenstände (Dinge) des normalen Alltags dazu befähigt werden, zu interagieren und sowohl online als auch autark zu kommunizieren. Viele Branchen wie Medizin, Automobilbau, Energieversorgung und Unterhaltungselektronik sind gleichermaßen betroffen, wodurch trotz Risiken auch neues wirtschaftliches Potential entsteht. Im Bereich "Connected Home" sind bereits Lösungen vorhanden, mittels intelligenter Vernetzung von Haushaltsgeräten und Sensoren, die Lebensqualität in den eigenen vier Wänden zu erhöhen. Diese Arbeit beschäftigt sich mit dem Thread Protokoll; einer neuen Technologie zur Integration mehrerer Kommunikationsschnittstellen innerhalb eines Netzwerks. Darüber hinaus wird die Implementierung auf Netzwerkebene (Network Layer) vorgestellt, sowie aufbereitete Informationen bezüglich verwendeter Technologien dargestellt.
