Experimental test-bench development using force control with industrial robots for the analysis of the mechanical response in car seats

Modern safe and high-quality products not only need to have desired properties in terms of geometry, material, features, etc. from a position-interaction point of view. Also compliance, deflection, impact and safety features depending on force-interacting properties are of (increasing) importance. As a key such example, the mechanical response of car seats has been studied, including the contact f

Comparing Ordinal and Ratio Scale Data in Requirements Prioritisation

The importance of prioritising requirements is widely recognised. A number of different techniques for prioritising requirements have been proposed, some based on an ordinal scale, others on a ratio scale. Different scales provide different levels of information, e.g. the ratio scale is richer than the ordinal scale. This paper aims to investigate the difference in information and aim to find ways

Constitutive relations, dissipation and reciprocity for the Maxwell equations in the time domain

The main goal of this paper is to establish general constitutive relations for the electromagnetic fields E,D,B and H in a time domain setting. The four basic assumptions of the medium are linearity, invariance to time translations, causality and continuity. These four assumptions imply that the constitutive relations are convolutions of Riemann-Stieltjes type. A review of the classifi- cation of

Antimonide Heterostructure Nanowires - Growth, Physics and Devices

Abstract in UndeterminedThis thesis investigates the growth and application of antimonide heterostructure nanowires for low-power electronics. In the first part of the thesis, GaSb, InSb and InAsSb nanowire growth is presented, and the distinguishing features of the growth are described. It is found that the presence of Sb results in more than 50 at. % group-III concentration in the Au seed partic
