In recent years, speech signal processing has benefited from a lot of attention, because of its widespread application. In this study, we have led a comparative analysis for efficient detection of Parkinson’s disease applied to machine learning classifiers from voice disorder known as dysphonia. To prove robust detection process, we used Artificial Neural Networks (ANN) and K Nearest Neighbors (KNN) algorithms, in the purpose of distinguishing between PD patient and healthy individual. Experimental results show that the ANN classifier achieved higher average performance than the KNN classifier in term of accuracy. The UCI Experiment consists of 31 subjects of which 23 were diagnosed with Parkinson's disease. The established system is able to distinguish healthy people from an acceptable range of people with PD with an accuracy rate of 96.7% by using ANN.

An ultrasound breast imaging system at central frequency of 4.5 MHz was implemented comprising sensors with a wide lateral radiation field distributed on a ring with respect the breast physiology. The temporal convolution function was used to define the maximum spatial resemblance between two received signals. This made it possible to quantify the ultrasonic intensity coupled, by impedance breakdown, to a suspicious cellular biomass.

Nowadays, autonomous driving represents a major challenge for automobile manufacturers in order to reach the latest levels of autonomy. Any autonomous vehicle development project focuses on three fundamental phases; environmental perception, trajectory planning and path pursuit which including control and command as an integral part. This paper presents a modified Sliding Mode Controller based on the Radial Basic Function Neural Networks (SMC_RBNN) able to control the lateral dynamics of the vehicle. For a sinusoidal reference path, the proposed control strategy, SMC_RBNN, showed better results than those obtained with a conventional Sliding Mode Controller (SMC), in terms of lateral tracking error.

In this paper, we aim to describe a novel technique which is a Combined Automatic Speech Recognition and Language Identification System that uses both ASR and LI technologies which consists of the recognition of spoken digits after identifying their language. An in-house corpus was used mainly for both speech-based multi-lingual identification and speech recognition tasks made of bilingual digits sounds that contains ten digits spoken mainly in two languages: Modern Standard Arabic (MSA) and Amazigh Moroccan dialect. First of all, we develop the Language Identification stage which is the basis of our hybrid system which behaves as front-end of our system that serves for spoken language detection. This facilitates the task of recognition by allocating the output to the appropriate Hidden Model Markov (HMM) based recognition system (Arabic or Amazigh) which improves recognition of a bilingual spoken digit efficiently. For this purpose, a set of parameters were adjusted on our CLIASR system to achieve good results, including classifier parameters, feature vector, and HMM-GMM parameters. The results show that our proposed LI-ASR system performs 33% better than an ordinary ASR for a given bilingual mixed speech corpus.

In this paper, single relaxation time (SRT) and multi-relaxation time (MRT) lattice Boltzmann method are used to simulate gas flow in a lid-driven micro-cavity. Simulation of such microflow requires suitable boundary conditions. In this work, a diffuse scattering boundary condition and a combination of bounce-back and specular boundary conditions are employed to obtain the slip velocity at the walls. The computations are carried out mainly for the slip and early transition regimes. The effect of the Knudsen number on the velocities profile and streamlines contours are shown. In the slip regime, the obtained numerical results agree well with existing results for both approaches. Whereas, in the transition regime, MRT-LBM gives good results contrary to the SRT-LBM which the validity breaks down.

In this paper, we present our study to choose a suitable method for the inspection of Moroccan Overhead High Voltage Transmission Lines (OHVTLs). So we present the traditional methods adopted by the electricity supply operators, their advantages and inconveniences. We prove that the use of Unmanned Aerial Vehicles (UAVs) in line diagnosis operations and the location of abnormalities stands out from the use of the other line inspection methods. We have established a comparative study of the different types of UAVs by determining their characteristics, advantages, and disadvantages, which proves that the multirotor UAV is a suitable choice for our case. Also, we elaborate the Vertical Take-Off and Landing (VTOL) UAV’s mathematical model and its simulation, we present a comparison of VTOL UAV’s types and a practical study of existing VTOL UAVs, which can be used in the inspection of overhead high voltage transmission lines, joined by their technical specifications.

Static converters of the power electronics have recently undergone a significant technological evolution, particularly to enhance their low efficiency and compactness resulting from the increase of the speed of semiconductor power components, which allows reducing the switching losses constituting a large part of the losses in static converters. However, the choice of precise geometrical layout and a specific technology to design converters using modern components usually produces some dimensioning problems due to heating, (dv/dt) and (di/dt). For this reason, after a functional design phase, a technological design phase should be followed for the final development of a converter. It is, therefore, essential to use accurate models to evaluate switching losses and to predict possible problems caused by the employment of other constraints such as heating. In this context of predicting switching and conduction losses, other performances of static converters can be useful. In this paper, we introduce a precise model to calculate losses in a converter and quickly estimate them with a good precision.

This paper proposes a nonlinear sensorless control of doubly fed induction generator (DFIG) in wind energy conversion system. The target is to ensure the optimization of wind energy captured without measurement of rotor speed. The feedback controller deals with the full order model of DFIG without considering any simplifying assumption. It guarantees an efficient tracking of both rotor speed and stator flux. The estimation of rotor speed involved in the control laws is provided by an observer. The system stability is proven using Lyapunov’s stability theory. Simulation results of the proposed sensorless controller have been carried out in Matlab/Simulink. It verifies the validity and good tracking performances of the proposed controller.

Compact super ultra-wideband (UWB) elliptical antenna with corrugations is presented in this paper. The working super UWB is achieved by using corrugations structure on the border of the radiating patch and notching and by trucking the ground plane. The antenna is printed on the FR4- Epoxy substrate with overall dimensions of 29.5×32×1.5 mm3. The antenna operates in the band 3.32 to upper than 20 GHz. In addition, the simulated results indicate that the antenna exhibits stable radiation patterns, acceptable gain and a good efficiency performance.
