This investigation has two main objectives. The first one is to propose a statistical method, based on the fourth order cumulants, to identify single-input single-output ‘SISO’, finite impulse response ‘FIR’ system using non gaussian input, zero mean…

This paper presents a fuzzy-logic-based vector control for a five-phase permanent-magnet synchronous motor (PMSM). The high-performance of the proposed fuzzy logic control (FLC)-based PMSM drive are investigated and compared with the conventional…

This work presents an intelligent approach for the performance improvement and optimization of the control of a photovoltaic system to track maximum power point under variable temperature and isolation conditions. First, we present the controller…

In this paper, we propose a new technique based on genetic algorithm for the extraction of electrical parameters (the saturation current, the serial resistance, the parallel resistance and the ideality factor). The models with five, seven and nine…

This work defines MM-Fuzzy Cone Metric Space, as a new metric space. It also analyzes possible forms of contractive conditions and groups them accordingly to set up generalized contractive conditions for self-mappings defined over MM-fuzzy cone…

Multi-crystalline silicon ingots of 44 cm square cross section, weighing 80 kg, have been produced by a modified Heat Exchanger Method in which a graphite insulation and heat exchanger block move down from the heater during crystal growth to…

The techniques of weather satellites images reception has quickly evolved in the last decade. At the beginning, the operation of building a reception station required considerable means, and only specialized institutions had access to these…

In Photovoltaic, many semiconductors materials are used. These materials possess different optical, electrical and mechanical properties. However, the present technologies used in the solar cell manufacture, depend essentially for the material and…

In this paper, we focus to highlighting the positive role of periodic operation which can be played for performance improvement of a hydrogen separator reactor integrating a palladium membrane. For this subject, a mathematical approach describing the…

Structural, mechanical and electronic structure properties of Mg7NbH16 were investigated using the norm-conserving pseudo-potentials and plane waves (PP-PW) within the general gradient approximation (GGA) in the frame of density functional theory…
