In this paper, the Singularity representation and workspace determination of the parrallel robot PAR4 are presented. The serial singularity (type 1) is determined using the kinematic matrix. This type of singularity indicates the unreachable points in the workspace. Based on the inverse geomatric model (MGI) of the parallel robot PAR4 the workspace is determined. Numerical results are presented showing some singularity of type 1 and their representation of the robot PAR4. Also, the workspace of this robot is presented.

Nowadays, high video resolution such as Full HD, 4K and 8K will become the most used in video systems. These resolutions are integrated in the HEVC (High Efficiency Video Coding) norm. However, these performances have been accompanied by an algorithmic complexity which affects directly the processing time. To overcome this complexity, parallel architectures presents an interesting solution for this problem. As part of this goal, we propose a solution based on SoC (System On Chip) technology for the implementation of the HEVC intra decoding chain. The HM16.20 code was used for HEVC encoding and decoding, and the Xilinx Vivado tool for the implementation of this code on the Zynq-7000 platform. In this work, we present a performance profiling in terms of execution time, power consumption and the used hardware resources.

In the last years, the brain tumor is considered as one of the most deadly tumors around the world. It can affect adults and children. The wrong classification of the tumor brain will lead to bad consequences. Consequently, the right identification of the type and the grade of tumors in the early stages has a significant role to choose a precise treatment plan. Due to the various brain tumor types and the big amounts of data, the manual technique for examining the Magnetic Resonance Imaging (MRI) images becomes time-consuming and can lead to human errors. Therefore, an automated Computer Assisted Diagnosis (CAD) system is needed to overcome these problems. We suggested a new CNN scheme to classify different brain tumors. The suggested model is experimentally evaluated on a benchmark dataset. Experimental results affirm that the suggested approach provides convincing results compared to existing methods.

Transmission line as a neutral system with variable delay, that can be affected by an actuator fault is studied in this paper. The main purpose of this work is the control design which guarantee Stability and Stabilization of transmission line system based on Lyapunov criteria. After that, a Robust H∞ fault tolerant control for this type of system is developed. Then, an active fault tolerant control by using a Pseudo-Inverse Method PIM for the transmission line with actuator fault is designed.

The delta inverter is suggested to be the smallest three-phase dc/ac converter topology. It includes only three power switches compared to six in the conventional inverter. This reduced inverter topology is widely considered in many industrial applications, such as the electric traction and the large photovoltaic conversion systems. In this paper, a new sinusoidal pulse width modulation algorithm (SPWM) is developed for the reduced delta inverter. This algorithm is achieved by the development of irregular modulating functions waveforms of the sinusoidal modulation switching technique generated specially for the unconventional delta inverter's structure. Simulation results of the proposed SPWM algorithm carried out on a delta inverter feeding a three-phase RL load are acquired. Digital Signal Processor (DSP) implementation of the proposed SPWM method have been developed using an experimental board build around the laboratory prototype of the reduced delta inverter associated with an RL load as a first step and a squirrel cage induction machine as a second one. Experimental results have underlined its high performances considering the proposed SPWM algorithm.

This paper presents the description, modeling, and control of an electrical energy production system based on a wind power system operating at variable speed. Such energy production systems are inevitably called upon for randomly varying wind speeds. Morever, MPPT control using fuzzy logic observer (FLO) for rotational speed estimation without using wind speed data is adopted. To improve and verify this approach's effectiveness, a quantitative and qualitative analysis of the energy generation system with a power of 1.5 MW is investigated by numerical simulation using Matlab/Simulink software. Thus, simulation tests validate the technique and improve the dynamic behavior of the system.

With the evolution of microgrids (MGs), the interconnected operation of MGs is becoming a promising approach for the smart grid. The purpose of this paper is to propose a power management strategy for interconnected MGs. A case study, compromising three MGs is considered. Each MG includes Renewable Energy Sources (RES), a battery Lithium ion (Li-ion) and diesel generator (DG). Using the power sharing framework and considering the local objectives of multiples MGs, the proposed strategy aims to maintain the power equilibrium between consumption and production in each MG via bidirectional interaction between interconnected MGs and the main grid. Results confirm the performance and the robustness of the proposed method.

Machine-to-Machine (M2M) is one of the emerging technologies that has caught the attention of many researchers. The heterogeneous connected objects, constrained by interoperability, security and confidentiality issues, is driving the emergence of the concept of the Social Internet of Things (SIoT). The latter consists of providing semi-autonomous communicating objects (CO) with interaction capacities inspired by human social relations. The SIoT concept contributes to the evolution of interaction between industrial objects, by improving deterministic mechanisms towards intelligent interactions. We propose a new concept of M2M interactions inspired by social paradigms. These paradigms are deduced from a synthesis of several sociological approaches.

In this paper we introduce the fuzzy Adaptive backstepping control type-2 interval (FABC) for a nonlinear system class. Faced with the difficulty of calculating the nominal model of a nonlinear system, the latter will be constructed using a fuzzy system type 2 Takagi-Sugeno (TS). The purpose of this paper is to exploit a (FABC) for a state-coupled two-tank system from its fuzzy model type-2. In the introduced approach, to make it sure for a globally asymptotically stabilisation for a specific category of secondorder nonlinear system, we design a robust controller standing on backstepping procedure. To sum up with, the purpose of this paper is validated through the simulation results.
