Elastocaloric cooling is an emerging solid-state cooling technology with the potential to provide environmentally friendly, efficient cooling. The elastocaloric effect in superelastic shape memory alloy films is used to develop advanced cooling devices for small-scale applications. Cascaded and parallelized devices are developed to increase device temperature span and cooling capacity. The concepts are proven experimentally, a maximum temperature span of 27° C is achieved in a cascaded device.

Grundlagen der Computergrafik und des Geometrischen Modellierens werden mit diesem Buch dargestellt. Es behandelt neuere rasterbasierte Techniken (z.B. Texturmapping und Anti-Aliasing), die in modernen Grafikbibliotheken und Grafikkarten von PCs ublich sind. Daneben werden Ray-Tracing und Radiosity Methoden und objektraum-definierte Modelliertechniken, sowie effiziente Algorithmen der Geometrie grundlegend besprochen. Zu den einzelnen Kapiteln sind Ubungsaufgaben angefuhrt.

Geometric constraint programming increases flexibility in CAD design specifications and leads to new conceptual design paradigms. This volume features a collection of work by leading researchers developing the various aspects of constraint-based product modeling. In an introductory chapter the role of constraints in CAD systems of the future and their implications for the STEP data exchange format are discussed. The main part of the book deals with the application of constraints to conceptual and collaborative design, as well as state-of-the-art mathematical and algorithmic methods for...
