A fully integrated Hall sensor microsystem with current-mode output

This paper presents a fully integrated Hall sensor microsystem with a current-mode output. The system operates in open-loop and includes a Hall sensor with internal biasing, a fully differential front-end, a preamplifier chain and a voltage-to-current conv ...

In-situ dynamic behavior of a railway bridge girder under fatigue causing traffic loading

Eugen Brühwiler, Andrin Herwig

Stresses in bridges due to traffic loading need to be determined as accurately as possible for reliable fatigue safety verification. In particular, the dynamic traffic effect due to running vehicles has to be considered in a realistic way. In-situ measurem ...

Dynamic analysis of laminated composite plates traversed by a moving mass based on a first-order theory

Elyas Ghafoori

The dynamic response of angle-ply laminated composite plates traversed by a moving mass or a moving force is investigated. For this purpose, a finite element method based on the first-order shear deformation theory is used. Stationary and adaptive mesh tec ...

Effects of filling in CoSb3: Local structure, band gap, and phonons from first principles

Nicola Marzari, Boris Kozinsky

We use ab initio computations to investigate the effect of filler ions on the properties of CoSb3 skutterudites. We analyze global and local structural effects of filling, using the Ba-filled system as an example. We show that the deformation of Sb network ...

Sparse Component Analysis for Speech Recognition in Multi-Speaker Environment

Hervé Bourlard, Philip Neil Garner, Afsaneh Asaei

Sparse Component Analysis is a relatively young technique that relies upon a representation of signal occupying only a small part of a larger space. Mixtures of sparse components are disjoint in that space. As a particular application of sparsity of speech ...
