The use of wavelet transform for an automated initialization in GPS/MEMS-IMU integration

Jan Skaloud, Adrian Wägli, Heidi Fournier

The main objective of this research is in automating the initialization phase of the MEMS-IMZ/GPS data integration. The motivation for this study is the special case where the before mentioned sensors are worn on a body (e.g. of an athlete) and where the u ...

Towards Generic Detection of Unusual Events in Video Surveillance

Touradj Ebrahimi, Frédéric Dufaux, Ivan Ivanov

In this paper, we consider the challenging problem of unusual event detection in video surveillance systems. The proposed approach makes a step toward generic and automatic detection of unusual events in terms of velocity and acceleration. At first, the mo ...

Multi-gate vibrating-body field effect transistor (VB-FETs)

Mihai Adrian Ionescu, Dimitrios Tsamados, Daniel Grogg, Marco Mazza

This paper reports on the design, fabrication and detailed characteristics of multi-gate vibrating-body field effect transistors (VB-FETs). Double-gate and four-gate VB-FETs with resonance frequencies of 2 MHz and 71 MHz, respectively, are successfully dem ...

Hydro Elastic Behavior of Vibrating Blades

François Avellan, Mohamed Farhat, Philippe Ausoni, Olivier Braun

Fluid-structure investigations in hydraulic machines using coupled simulations are extremely time-consuming; therefore we develop an alternative method. In this paper, a model is proposed to predict fluid-structure coupling by linearizing the hydrodynamic ...

Jet-Scheduling Control for SpiderCrane: Experimental Results

Dominique Bonvin, Christophe Salzmann, Philippe Müllhaupt, Davide Buccieri

SpiderCrane is a three-dimensional crane, whose main particularity lies in the absence of large inertial moving parts. This paper presents experimental results obtained with the novel jet-scheduling control methodology that is based on differential flatnes ...

Comment on « Angular distributions of H-induced HD and D2 desorptions from the Si(100) surfaces » [J. Chem. Phys. 124, 054715 (2006)]

Régis Bisson

In their article, Inanaga et al. have presented an angular distribution for the desorption of hydrogen molecules induced by hydrogen atoms impinging on a hydrogenated Si(100) surface and compared the measurement with classical trajectory calculations based ...

Dynamic Visual Attention: Motion Direction versus Motion Magnitude

Heinz Hügli, Alexandre Bur

Defined as an attentive process in the context of visual sequences, dynamic visual attention refers to the selection of the most informative parts of video sequence. This paper investigates the contribution of motion in dynamic visual attention, and specif ...

Nano-gap micro-electro-mechanical bulk lateral resonators with high quality factors and low motional resistances on thin silicon-on-insulator

Mihai Adrian Ionescu, Daniel Grogg, Marco Mazza, Nicoleta-Diana Ciressan

The design, fabrication and experimental investigation of 22-25 MHz fragmented-membrane MEM bulk lateral resonators (BLR) with 100 nm air-gaps on thin (1 and 6 [mu]m) silicon-on-insulator (SOI) are reported. Quality factors as high as 120,000 and motional ...

UWB and MEMS Based Indoor Navigation

Bertrand Merminod, Sylvain Pittet

Thanks to its physical characteristics, Ultra-wideband (UWB) is one of the most promising technologies for indoor pedestrian navigation. UWB radio localisation systems however experience multipath phenomena that decrease the precision and the reliability o ...

Fast-Marching Tractography for Connection Matrix (Fast-TraC)

Jean-Philippe Thiran, Reto Meuli, Patric Hagmann, Leila Cammoun, Xavier Gigandet

Although high angular resolution diffusion MRI techniques are able to solve multiple intra-voxel fiber orientations, the usual streamline Diffusion Spectrum Imaging (DSI) tractography algorithms present some limitations in their ability to map complex fibe ...
