This paper aims defining features to characterize Parkinsonian voice affected by tremor. It uses quasi-sinusoidal modelling of signals which assumes that speech signal is a sum of sinusoids with time-linearly varying instantaneous amplitudes and frequencies permits. The parameters of this model are calculated and their behavior is analyzed. The statistical analysis using box-plots permits to show the ability of this model to discriminate the Parkinsonian voice from the healthy voice.Index Terms-Parkinson's disease, tremor, quasi-sinusoidal model, features for discrimination.

This paper presents the experimental results of an original control strategy for motor-pump implemented on a dSPACE controller board. The Power Field Oriented Control strategy developed in this paper is used to drive a motor-pump fed by intermittent renewable sources. This system is dedicated to autonomous applications for pumping or water desalination for remote areas without access to hydraulic and electric networks. This control strategy allows controlling the DC bus voltage without using batteries in the system. The DC voltage control is achieved through the control of the inverter used for the motorpump. Experimental results for variable power source are presented and confirm the effectiveness of the proposed control strategy.
