This paper deals with e-learning design and development training courses, more precisely with remote training by practical activities of laboratory experiments (E-Lab). Indeed, the majority of remote training platforms offer theoretical courses and a few practical activities, which are essential in training theoretical Science and Technology. In order to share the costly equipment, in this work, we propose an open hardware/software architecture allowing remote access to a laboratory equipment by designing in Matlab two graphical interfaces using Internet/Intranet network and TCP/IP communication protocol. A real-time control and supervision is performed to carry out all the practical activity according to a pedagogical scenario elaborated by the trainer. The use of these interfaces is illustrated by educational sessions articulated on the Proportional Integral Derivative (PID) regulation and the Generalized Predictive Control (GPC) of temperature control system. The challenge of elaborating a remote practical activity with pedagogical effectiveness is accomplished in the above proposed solution. All the hardware and software that made available the remote experimentation platform give possibility to achieve others traditional activities in experimentation laboratory.

This paper aims to present a new robust command called active disturbance rejection controller (ADRC) applied to the sensorless induction motor and introduces the problem of the parameters, which significantly deteriorate the performance of the control, this variation introduces an important role in the loss of dynamic performance in an undesirable coupling between flux and torque of the machine. This paper offers a new scheme for estimation of induction motor speed using αβ representation of the model in the stationary reference frame and measurements of accessible motor variables only (currents, voltages and speed). A second-order of MRAS based sliding mode estimator is designed for speed estimation. The proposed schemes are implemented using MATLAB simulation, improve the system robustness against motor parameter variations and increase the performance of the speed loop controller.

This paper deals with the characterization of the fetal electrocardiogram signal by using only the continuous wavelet transform. Clinically significant information in the fetal electrocardiogram signal is often masked by maternal electrocardiogram mECG considered as the most predominant interference. The aim of this work is to characterize the complex QRS and to estimate the RR interval in order to diagnose fetal heart arrhythmia such as Bradycardia and Tachycardia and this without being obliged to extract the fetal signal from that of the mother. We focus on both time domain and frequency domain to extract the useful characteristics of the signal.

This paper presents a diagnostic method based on I-V characteristic analysis and Artificial Neural Networks (ANN). A number of attributes are estimated using a simulation model based on a set of working conditions such as solar irradiance and module's temperature. The estimated attributes are then compared with those obtained from the real PV array measurements, which lead to the detection of possible faulty operating conditions. After detecting the presence of possible fault, tow algorithms are developed in order to isolate and identify eight different types of faults. The simulation results show that the proposed method can detect and classify the different faults occurring in a PV array with a high accuracy.

In this paper, we describe an FPGA implementation of the optical flow (OF) algorithm for real time estimation of moving objects from a video sequence. Lucas-Kanade (LK) approach has been chosen to meet the real time and hardware resource constraints. In our approach, to allow accurate calculation, we adopt a high level synthesis approach to increase the accuracy of the system and to more deal with fixed-point precision. Hardware designs of the architectures are performed using Xilinx System Generator from Xilinx (XSG) and Modelsim tools. The proposed architecture is validated by a hardware co-simulation.

In recent late the IEEE has scheduled the standardization group 802.15.7r1 “ Short Range Optical Wireless Communication”, which is currently in the treatment of expanding a standard for visible light communication (VLC) and aims to deliver peak data rates of 10 Gbits/s. As with any other communication system, processing the performances studies depend on a realistic channel model and its impulse response. Thus, it is a compulsory condition that the features of the channel are well understood to design and operate efficient optical communication shape. Lights are installed everywhere around us; in public places, houses, streets. Since lights represent a crucial part of our daily lives, I find it a mandatory condition to study the subject matter. In this paper, our main objective is to study the influence of both FOV(field-of-view) and the reflections on channel impulse response (CIR) with different path LOS (Line-Of-Sight) and NLOS(Non-Line-Of-Sight) using a room size of 4.0mx 4.0mx 2.5m with the transmitted optical power of a LED up to 1W.

This paper presents a nonlinear control of the active and reactive power for a photovoltaic system. This latest is connected into the grid via transformless voltage source inverter. The design of the controller is based on the Backstepping approach to establish the inverter control laws. An analysis based on Lyapunov stability approach is developed to guarantee the global asymptotic stability of the system. In order to verify the effectiveness of the proposed controller, the obtained results are compared with those of the conventional linear controllers under changing in solar irradiance. The results show that the proposed control laws provide better performance in terms of references tracking and unity power factor. Furthermore, the harmonic performance and total harmonic distortion revealed that the power quality injected into the electrical network are enhanced using the Backstepping control strategy.

In this research a novel planar monopole antenna for dual band applications is proposed. The antenna topology operates at two operating frequencies at 4.1 and 11.3 GHz which covers C and Ku bands. The proposed design consists of a quasiegg-shaped radiating patch and partial ground plane. A stepped cut in the radiating patch and the partial ground plane are used, to obtain the dual band antenna. The proposed antenna is printed on the FR4 substrate and is optimized by computer simulation technology (CST) and occupies an area of 11.5 × 16.6 × 1.6 mm3. The desired resonant frequencies are obtained by adjusting the length of cut stepped slits in the both sides of quasi egg Quasi Egg-Shaped radiated patch and of the partial ground plane. The proposed topology achieves good impedance matching, return loss (greater than −10dB), radiation patterns and consistent gain at all two operating bands. The proposed antenna has VSWR < 2 except the 5.11–9.79 GHz band. Detail of the proposed antenna design, simulated for the return loss parameter are described and discussed.

With the fast development of IT industry, our reliance on the functioning of software systems is growing rapidly. These systems are becoming more and more complicated and are massively encroaching on daily life, e.g., the Internet, embedded systems, mobile devices and so on. The design and verification of concurrent and real-time systems are notoriously difficult problems. Among the software validation techniques, model checking approach has been proved to be successful as an automatic and effective solution. In this paper, we propose a methodology for the modeling and verification of the Real-Time and Hybrid Systems. The Real-Time Maude tool has been used to formally model, simulate, and model check real-time and hybrid systems. This paper also shows via a case study how Real-Time Maude search analysis found a previously unknown behavior that led to missed deadlines. First, the case study is modeled using timed and/or hybrid automata and then SysML's state machine diagram is described, for allowing more precise specification. The specified model is verified against specified LTL properties using Maude LTL Model Checker.

In this paper, we introduce a new method for categorisation natural image based on different techniques. Concerning the color and texture, we made a pre-treatment to convert the database images on to the gray-scale and the Haar wavelet transformation. For this, we use the Oriented Gradient Histogram (HOG) for each sub-band to extract these image features. We have used a proper classification based on the support vector machine (SVM) to recognize these images. The result part and experience applied on a Corel database that is known in natural images shows a better performance of the proposed system based on accuracy and speed compared to other CBIR methods.
