Wettability of Glass Fibers in Reactive Thermoplastic/Polyester Blends: Comparison between Compatible and Incompatible Thermoplastics

The evolution of morphology of reactive thermoplastic/unsaturated polyester blends at the surface of glass fibers is investigated during curing. The study focuses on two different types of thermoplastics, incompatible and compatible respectively with the p ...

Model-Free Precompensator and Feedforward Tuning Based on the Correlation Approach

Alireza Karimi, Roland Longchamp, Mark Edward John Butcher

High performance output tracking can be achieved by precompensator or feedforward controllers based on the inverse of the closed-loop system or the plant model. However, it has been shown that these inverse controllers can affect adversely the tracking per ...

Iterative Correlation-Based Controller Tuning

Dominique Bonvin, Alireza Karimi, Ljubisa Miskovic

This paper gives an overview on the theoretical results of recently developed algorithms for iterative controller tuning based on the correlation approach. The basic idea is to decorrelate the output error between the achieved and designed closed-loop syst ...

Non-Quasi-Static (NQS) Thermal Noise Modelling of the MOS Transistor

Christian Enz

A non-quasi-static (NQS) thermal noise model of the MOS transistor is presented that is valid in all modes of operation, from weak to strong inversion, and up to frequencies which are near or above the NQS cut-off frequency. It is shown that in addition to ...

α-relaxation processes in binary hard-sphere mixtures

Giuseppe Foffi, Francesco Sciortino

Molecular-dynamics simulations are presented for two correlation functions formed with the partial density fluctuations of binary hard-sphere mixtures in order to explore the effects of mixing on the evolution of glassy dynamics upon compressing the liquid ...

Cross-correlated relaxation in NMR of macromolecules in the presence of fast and slow internal dynamics

Geoffrey Bodenhausen, Daniel Abergel

We present an anal. of correlation and spectral d. functions involved in autorelaxation and cross-correlated relaxation in the magnetic resonance of macromols. Internal dynamics of the macromol. are described in terms of 2 distinct fluctuation processes wi ...

Gait assessment in Parkinson's disease: toward an ambulatory system for long-term monitoring

Kamiar Aminian, Catherine Dehollain, Arash Salarian

An ambulatory gait analysis method using body-attached gyroscopes to estimate spatio-temporal parameters of gait has been proposed and validated against a reference system for normal and pathologic gait. Later, ten Parkinson's disease (PD) patients with su ...

Pedestrian head detection using automatic scale selection for feature detection and statistical edge curvature analysis

Jean-Philippe Thiran, Gianluca Antonini

In this report we focus on pedestrian head detection and tracking in video sequences. The task is not trivial in real and complex scenarios where the deformation induced by the perspective field requires a multi-scale analy- sis. Multi-scale shape models f ...

Acoustic observations of zooplankton in lakes using a Doppler current profiler

Alfred Johny Wüest

In this paper we test the usefulness of acoustic backscatter measurements from a 614 kHz Acoustic Doppler Current Profiler (ADCP) for the qualitative and quantitative characterisation of zooplankton distributions in lakes. ADCP-based backscatter estimat ...

Correlations of f10.7-cm flux and temperature with male traffic-accident mortality for the years 1980-1999

Stephan Morgenthaler

Significant positive correlation was found between f10.7-cm flux and male traffic-accident mortality for the years 1980-1999 in Japan. On the other hand, significant negative correlation was found between annual mean temperature and male traffic-accident m ...
