Scenarios are effective conceptual tools for requirements elicitation, analysis, and evaluation. However, choosing salient scenarios is one of the major problems of scenario-based web design. On one hand, due to the partiality of scenarios, it is often difficult to envision up-front all the scenarios necessary to cover every interaction capability to be designed for the site. On the other hand,...

Electricity demand response refers to consumer actions that change the utility load profile in a way that reduces costs or improves grid security. The focus of demand response has mainly been on the commercial and big industrial sectors because of the large demand reduction that they can offer to the utility grid operators. Utilities are showing increasing interest in residential demand respons...

Motion estimation (ME) is a key encoding component of almost all modern video coding standards. ME contributes significantly to video coding efficiency, but, it also consumes the most power of any component in a video encoder. In this paper, an ME processor with 3D stacked memory architecture is proposed to reduce memory and core power consumption. First, a memory die is designed and stacked wi...

This paper presents a proven and reusable methodology (MiLE) for performing a costeffective usability evaluation of an e-learning web application. MiLE is a scenario-driven inspection technique which is based on the concepts of user profile, user goal, scenario, and usability attribute. Mitigating the drawbacks and merging the respective benefits of state-of-the-art methods for usability evalua...

3D stacking of dies is an enabler for further miniaturization and increase of functionality. Individual dies are thinned down aggressively – down to approximately 20 um – and glued on top of each other. With such 3D ICs, the same power dissipation will lead to higher temperatures in a stacked-die package compared to a single-die package. Hence, there is a need to perform detailed thermal analys...

The addition of wood to polymers results in wood-polymer composites (WPC), whereby the content can be up 80 %. This composite is mainly processed extruded deckings. extrusion die an essential part process, which determines both process parameters and final product. A characteristic WPC dies a partial solidification melt before leaving die. necessary ensure dimensionally stable extrusion. For de...

In recent years, in order to reducing die design and manufacturing costs, Multi point forming technique has gained an increasing interest because of its high flexibility. In this process, the conventional fixed shape solid die sets are replaced with a pair of opposite matrices of controllable elements. In this paper, the fundamental principles of multi-point forming was described and the possib...

Ein wesentliches Motiv für die Einführung von serviceorientierter Architektur (SOA) ist die Überwindung fachlicher, technischer und organisatorischer Heterogenität. Im föderalistischen Kontext der Schweiz geht diese Heterogenität einher mit der weitgehenden Autonomie der Organisationseinheiten, die Verwaltungsprozesse bearbeiten. Folglich unterscheiden sich die Verwaltungsprozesse in der Art, A...
