Out-of-Equilibrium Measurements of Kinetic Constants on a Biosensor

Conventional measurements of kinetic constants currently in use are performed at equilibrium and may require large volumes, especially at low association rate constant k on. If the measurements are made out of equilibrium, the values obtained may be…

Closed-loop output error identification algorithms with predictors based on generalized orthonormal transfer functions: Convergence conditions and bias distribution

This paper proposes an improved version of closed-loop output-error identification algorithms, where the predictor is established on a generalized basis of orthonormal transfer functions. It is shown that the selection of the basis poles impacts the…

Direction-of-Arrival Estimation through Exact Continuous l20-Norm Relaxation

On-grid based direction-of-arrival (DOA) estimation methods rely on the resolution of a difficult group-sparse optimization problem that involves the l20 pseudo-norm. In this work, we show that an exact relaxation of this problem can be obtained by…

Improving motorcycle motion perception by using innovative motorcycle headlight configurations: Evidence from simulator and test-track experiments

Many motorcycle accidents occur at intersections and are caused by other vehicle drivers who misperceive the speed and time-to-arrival of an approaching motorcycle. The two experiments reported here tested different motorcycle headlight…

Effect of load sequence interaction on bond-wire lifetime due to power cycling

Experimental investigations on the effects of load sequence on degradations of bond-wire contacts of Insulated Gate Bipolar Transistors power modules are reported in this paper. Both the junction temperature swing (ΔTj) and the heating duration (tON…

Anisotropic neighborhoods of superpixels for thin structure segmentation

In the field of computer vision, image segmentation aims at decomposing an image into homogeneous regions. While usually an image is composed of a regular lattice of pixels, this manuscript proposes through the term of site a generic approach able…

Etude Multi-Echelle et Multi-Physique de l’Ordre d’Introduction des Phases d’une Emulsion

Pour optimiser la stabilité d'une émulsion, une investigation multi-échelle est nécessaire. Les moyens préventifs classiques d'étude se font par l'analyse de l'inversion de phase (H/E ou E/H) ou par le changement de paramètres, tels que la…

Investigation on magnetic properties of mechanically alloyed τ-MnAlC with Fe addition

The influence of Fe addition on thermal stability, crystallography, and magnetic properties of τ-Mn51Al47C2 was investigated. Alloys with composition Mn51-xFexAl47C2 (x = 0, 0.5, 1, 2, and 4) were synthesized by mechanical alloying method. High…
