In this paper, we investigate a new method to analyze electrocardiogram (ECG) signal, extract the features, for the real time human identification using single lead human electrocardiogram. The proposed system extracts special parts of the ECG signal starting from the P wave, the QRS complex and ending with the T wave for that we used the multiresolution wavelet analysis. Different features are selected...
The aim of the present study is to characterize the electrical and electrostatic properties of the four kinds of cereal grains namely barley, durum wheat, soft wheat and impurities. The samples were charged by exposing them to a negative corona discharge generated by a needle electrode, facing a grounded plate electrode. Surface potential decay and electric charge measurements were recorded in order...
In this study, we proposed an analysis method of ElectroMyoGraphic (EMG) signals in order to diagnose and to identify neuromuscular pathologies (i.e.; myopathy and neuropathy). Analysis is performed fully automatically without expert assistance and without prior segmentation of muscle contractions. The method is based on Huang-Hilbert transform (HHT) which is a data-driven algorithm that decomposes...
In this paper, we analyze the performances of the Cell Averaging based on Lookup Tables (CA-LT) detector considering distributed targets embedded in Pareto distributed clutter. Assuming that the clutter parameters are not a priori known, the detector's structure is associated to an estimation approach that estimates the clutter parameters. The latter are used to select the suitable threshold factor...
A CPW rectangular-ring antenna over an Artificial Magnetic Conductor (AMC) is presented in this work. The AMC is designed as a dual-band structure having an array of unit cells and operates at 2.45GHz and 5.20 GHz. A CPW antenna uses this dual-band AMC structures as a back-plane. Performance comparison is carried out with and without the incorporation of AMC. The simulated and measured results show...
This paper is concerned with the design of a robust position Backstepping tracking controller for a permanent magnet synchronous motor (PMSM). A Backstepping control law is designed from the input-output linearization of the PMSM model, written in d-q coordinates. This controller is adapted via the estimation of the unknown load torque and friction effects. A linear extended state observer is devised...
This paper presents a novel centralized cooperative scheme which combines compressed sensing (CS) method based on the analog-to-information converter (AIC) with statistical and graphical chi-square Quantile-Quantile (QQ) plot detector. The received signal at every cognitive radio (CR) user in the presence of Additive-White-Gaussian-Noise (AWGN) and intentional interference attack signal (jamming)...
In this paper, two approaches to speed estimation, presented in the literature, for a sensorless control of double star induction machine. We will discuss briefly the advantages, disadvantages, and limits of use of these techniques. We will then apply these two sensorless control techniques to the double star induction machine. The simulation results obtained showed that the speed sensorless vector...
Recent technological advances allowed the word to construct several wearable products that can capture and process the human body bio-signals. The PPG signal becomes one of the most contenders in heart rate monitoring due to their prominent features, flexibility, effectiveness and low costs. This paper present a novel System of PPG Heart rate calculation based on FPGA, using the Pan and Tompkins as...
This work is devoted to study the influence of the increasing of the width of the polluted band on insulators used in desert regions, by measuring the leakage current through the insulators surface. The Recurrent Plot technique (RP) is used to analyze the leakage current (LC) signal for monitoring the insulators surface state. This technique is applied directly on the leakage current waveforms, and...
In this paper simulation studies have been conducted using Simulink/MATLAB software in order to investigate the impact of STATCOM on the positive-offset mho element loss of excitation (LOE) protection scheme in synchronous generator. The obtained results show that the operation of the positive-offset protection scheme takes more time under the integration of STATCOM in the transmission line. Moreover,...
In this note, an adaptive fuzzy logic control (AFLC) strategy based on active sliding mode theory is considered to control a class of chaotic fractional-order systems. The main contribution in this work is the use of a saturation function to eliminate the chattering action in the control and surface signals. The nonlinear fractional order chaotic systems are identified using fuzzy logic sets. Based...
In this paper, we propose a modified architecture of a Pi-Sigma Neural Network (PSNN) based on two modifications: extension of the activation function and adding delays to neurons in the hidden layer. These new networks are called respectively Activation Function Extended Pi-Sigma (AFEPS) and Delayed Pi-Sigma (DPS) are obtained first by adding an activation function to all hidden neurons and secondly...
In this paper, a Distance-Weighted K Nearest Neighboring (DW-KNN) topology is proposed to study self-organized aggregation as an emergent swarming behavior within robot swarms. A virtual physics approach is applied among the proposed neighborhood topology to keep the robots together. A distance-weighted function based on a Smoothed Particle Hydrodynamic (SPH) interpolation approach is used as a key...
A design of a feed-forward-based fractional-order model reference adaptive control (FO-MRAC) compensator using a modified MIT rule to control a DC-DC boost converter is presented in this work. As the plant is non-minimum phase, an implementation of the so-called parallel feed-forward configuration is required to make the plant satisfy ASPR (almost strictly positive real) conditions that in turn, allows...
Iron-Cobalt (Fe-Co) ferrite nanocrystalline materials have been widely applied in microwave and radio frequency devices, such as circulators. Magneto-dielectric nanocrystalline were synthesized by mechanosynthesis (high energy mechanical grinding). Samples were taken at different grinding times. Toroidal samples were made by compact method at room temperature. In this work, the effect of mechanosynthesis...
