An ambulatory system to quantify bradykinesia and tremor in Parkinson's disease

Two groups of 10 Parkinson’s disease (PD) patients and 10 age-matched Normal subjects performing normal life activities were recorded using a portable recorder and 3D gyroscopes. PD patients had sub-thalamic stimulation implantation for 20±3 months. The PD ...

Adaptive Joint Playout Buffer and FEC Adjustment for Internet Telephony

Jean-Yves Le Boudec, Catherine Boutremans

We develop a joint playout buffer and Forward Error Correction (FEC) adjustment scheme for Internet Telephony, which incorporates the impact of end-to-end delay on the perceived audio quality. We show that it provides better quality than the adjustment sch ...

Falling risk evaluation in elderly using miniature gyroscope

Kamiar Aminian, Philippe Robert, Bijan Najafi

The time of sit-stand and stand-sit transition and its duration were measured using a miniature gyroscope on the chest and a portable recorder on the waist Based on a simple model and wavelet analysis, three parameters related to postural transition, namel ...

Bi(2223) Ag sheathed tape characterisation under DC applied magnetic field

Bertrand Dutoit, Marten Sjöström

An original electrical AC loss experimental set-up is presented. For loss comparison purpose, Ic and exponent n are measured with a DC magnetic field between 2 and 400 mT applied perpendicularly to the axis of the sample using a specially designed electrom ...

Synthetic vision and audition for digital actors

Daniel Thalmann

We present an overview of some principles of synthetic vision and audition for digital autonomous actors in virtual worlds. After a short review of the state of the art we focus on some aspects of synthetic vision and virtual world constraints. Then we pre ...

Measurement and Modeling of the Dynamic Behavior of Ag sheathed Bi(2223) Superconducting Tapes

Martin Hasler, Bertrand Dutoit

The purpose of this work is to predict the behaviour of electric devices using superconducting tapes, including the transition of those tapes to the normal state, which implies a typical non linear behaviour. The frequency domain studied is as wide as poss ...
