This paper presents an application of particle swarm optimization algorithm (PSO) to tune the scaling gains of Adaptive Neuro-Fuzzy Inference System (ANFIS) controller with a multi-closed loop control applied to nonlinear quadrotor system. First, PID control approach is used to obtain the training data set that is necessary to ANFIS design. Precisely, only the error and the error rate inputs in addition to output are used in training data set vector. Afterwards, an adaptive Neuro-Fuzzy inference system controller is designed. Then, to tune the scaling gains associated with ANFIS controller, PSO algorithm is used. Finally, an integral control action is added to the ANFIS controller output for controlling each state of the MIMO quadrotor system. The simulation test show that the results obtained with ANFIS-PSO controller are better, when compared to those obtained using conventional ANFIS controller and traditional PID.

The work presented in this paper concerns the optimization of the color of wastewater by the tannery, under the effects of factors that have significant impacts. The aim is to reduce the pollution caused by colored industrial waste from the tannery. This study is based on the application of the experiments design, during the physicochemical treatment of colored industrial tanneries waste, from the city of Mohammedia. The modeling established by design of experiments, makes it possible to analyze the color more deeply by taking into account the various relevant factors governing it. The design of experiments introduced is a homogeneous set of tools and algebra-statistical methods aimed at establishing and analyzing the relationships between the quantities studied (responses) and their sources of variation (factors). In this work, this analysis is a quantitative study: methodology of response surfaces (variation of responses depending on influencing factors). Its purpose is to determine a mathematical model, of the second order in order to characterize the color corresponds to the absorbance of wavelength 254 nm (the response), which is expressed as a function of the factors (the coagulant, the concentration flocculant and pH). This modeling is deduced from the data obtained from a series of experiments. optimizing the color studied is a specific method of constructing response surfaces, based on the central composite design. The validation of the theoretical model has been demonstrated by the experimental results.

Several studies have raised the issue of the adoption of model-driven engineering (MDE) in industry. We can find there, for example, the lack of mature tools and the lack of employee training. In this paper, we present a summary of 20 years of experience in MDE and how our vision has evolved through all these years. We present our view of an effective approach for a better application of MDE which answers to some of the issues raised. This approach is supported by a set of integrated tools that facilitate not only the learning of MDE but also its implementation. We also discuss some of the results of adopting this approach in university software engineering courses and its use in real software development projects.

This work presents a performance study of static power converters (SPC) for a self-excited induction generator (SEIG) driven by a wind turbine emulator (WTE). The WTE consists of an induction motor (IM) tied to an electrical grid via a variable speed drive (VSD) controlled by a wind turbine model block. The SPC control is based on regulation of the inductance current and the output voltage. However, the overall control design is modeled on Matlab/Simulink through block diagrams in which power and control stages are designed separately. A given wind profile scenario is proposed in order to evaluate the performance of the control strategies of the SPC with the WTE.

Nowadays, the use of renewable energy including wind energy has increased dramatically. Thanks to the wind energy conversion systems which are more sophisticated, and the demand for new techniques and algorithms to improve the control of wind turbines; using modern or classical approaches. To optimize the efficiency of the wind turbine, the latter should vary its rotational speed in real-time to follow the instantaneous variation in wind speed. The paper proposes an intelligent controller which is based on advanced RBF-NN approach, for torque control of doubly fed induction generator based wind turbine during all value of wind speed. The ultimate objective is to maximize output power for this system. For this, the online training RBF regulator approximates the torque of the generator in according to maximum power of the wind turbine at a given wind speed. This method is analytically compared with optimal torque controller to demonstrate the relevance of this controller, illustrate maximum power point tracking and good accuracy. Uniform asymptotic stability of the tracking error origin, is analyzed via Lyapunov method.

Soft Open Point (SOP) is a type of power electronic component used for reconfiguration of network distribution, which can replace the traditional switches or Normally Open Point (NOP). This article suggests an adaptive distribution network strategy that works with and without SOP to reduce power losses. To investigate the performance of our proposed system a distribution network constituted of two feeders and six loads was performed using Matlab/Simulink and Power System Analysis Toolbox (PSAT). The simulation results shown in this paper improve that the use of SOP reduces greatly the power losses in the distribution network.

Behavioral Finance studies demonstrated over the last decade that stock market can be driven by emotions for market participants. On the other hand, online sentiment tracking over social media network and news showed promising results in predicting financial markets. Hence, measuring investor sentiment has become a key research issue in financial predictions. In this paper, we present our methodology for collecting, analyzing and inferring sentiments from several information sources regarding Casablanca Stock Exchange Market. With this data we apply sentiment analysis and machine learning algorithms to infer the relationship between the general public view regarding a stock and its evolution within the stock market.

In this study, the analysis of microelectronic and photonic structure in one dimension program [AMPS-1D] has been successfully used to study organic solar cells. The program was used to optimize the performance of the organic solar cells based on (Carbazole-Methylthiophene), benzothiadiazole, Thiophene [(Cbz-Mth)-B-T]2 and [6, 6] -phenyl-C61-butyric acid methyl ester (PCBM). The cells considered, consist of Carbazole-Methylthiophene-Thiophene as electron donors, and benzothiadiazole, (6,6)-phenyl-c61-butyric acid methyl ester [PCBM] as electron acceptor. [(Cbz-Mth) -BT]2-PCBM] is used as photo active material, sandwiched between a transparent indium tin oxide (ITO) and an Al backside contact. The optoelectronic properties of these dyes were investigated by using the Density Functional Theory DFT/B3LYP/6-31G (d, p) method. We studied the influence of the variation of the thickness of the active layer, the temperature and the density of the effective states of the electrons and the holes in the conduction and valence bands respectively on the performance of the solar cells. The results were compared with the experimental data, it showed that the optimum thickness of the solar cell is about 120 nm, the maximum efficiency for the studied organic solar cell is about 9.458 % and the open circuit voltage decreases with temperature.
