Artificial intelligence is used in different fields. This paper describes a new opportunity to connect artificial intelligence to cognitive social psychology. We touch two important psychology paradigms: emotional and cognitive dissonance. Our hypotheses are proved using the new video based emotions analysis system (VEMOS) by testing labeled videos samples filmed by an actor according to specific scenarios and situations proposed by an expert on cognitive psychology describing the two paradigms. First, our approach has shown relevant results that confirm the notion of emotional and cognitive dissonance and the reliability of the intelligent system VEMOS on recognizing emotions efficiently. Then, we successfully add a new method of measuring a score of the individual emotional dissonance as well as his degree of spontaneity and degree of control.

The maximum power point tracking algorithm in wind power system design is considered an important point, to increase the efficiency of wind turbines power, in addition to regulating the voltage and frequency loops, energy must be extracted from the wind very efficiently, so it is necessary to design an effective control strategy. This paper presents an adaptive tuning structure, for capturing the maximum power points of controlling the wind energy conversion system, according to a permanent magnet synchronous generator. The optimum rotational speed of the generator is obtained utilizing the tip speed ratio strategy. Maximum power extracted at each wind speed is maintained, using a dimensional fuzzy logic control (DFLC) that is applied to the machine side converter. Adaptive DFLC controller is used in complex non-linear systems. The new control adopts two ideas, first to locate system states to a specific region in the form of calculating dimensional (distances, surface), then to design a fuzzy control law that will maintain the system in this zone. To confirm the efficiency and reliability of the suggested adaptive control, a simulation was executed using the MATLAB/Simulink program. The results showed the superiority of the new control as it was observed that the control can extract maximum power under variations of the wind speed profile, through its response speed and settling time. The paper contains extensive results.

Much existing voice conversion (VC) systems are attractive owing to their high performance in terms of voice quality and speaker similarity. Nevertheless, without parallel training data, some generated waveform trajectories are not yet smooth, leading to degraded sound quality and mispronunciation issues in the converted speech. To address these shortcomings, this paper proposes a non-parallel VC system based on an auto-regressive model, Phonetic PosteriorGrams (PPGs), and an LPCnet vocoder to generate high-quality converted speech. The proposed auto-regressive structure makes our system able to produce the next step outputs from the previous step acoustic features. Further, the use of PPGs aims to convert any unknown source speaker into a specific target speaker due to their speaker-independent properties. We evaluate the effectiveness of our system by performing any-to-one conversion pairs between native English speakers. Objective and subjective measures show that our method outperforms the best non-parallel VC method of Voice Conversion Challenge 2018 in terms of naturalness and speaker similarity.

Visual informations is very rich to control and pursue mobile robots, like wheeled mobile robots, underwater robots and aerospace mobile robots, etc. These are considered as mobile robots that move in different spaces, their main problem in this case is navigation especially in unknown environments. In effect, this navigation is possible only by the localisation and orientation of the robot by using different embedded sensors. We have the camera which is a necessary sensor in this work, it is an embedded instrument that gives very rich visual information as a sensor complementing the other sensors. In this context, the recognition of objects from visual informations is a main function among the functions very useful in image processing tasks due to its varied applications in the field of robotics. Based on the analysis of this informations and the determination of image features like color or shape or object primitives (points, lines, edges, etc.) or some other features. What interest us in this paper, various feature extraction techniques and classification of point and edge detection are discussed which are required for object recognition showing advantages and disadvantages of the selected algorithms. So, points and edge detection refers to the process of identifying and detecting sharp discontinuities in an image. In this work, we try to develop a novel algorithm using the work on the existing to create a novel detector.

Modern power systems, such as DC-AC inverters, have improved in efficiency. They employ simple control methods. During the switching process, however, they cause harmonic difficulties. This has an effect on the overall system's performances. To reduce these undesired harmonic distortions, unipolar Selective Harmonic Elimination SHEPWM was used in this work. At optimal switching angles, it cancels out odd harmonics. Its goal is to get rid of the first 100 low-order harmonics. By solving non-linear transcendental equations in MATLAB, the fsolve function was utilized to calculate the optimal 50 angles for the SHEPWM. The resulting SHEPWM control signal is implemented in LTspice. It operates a single-phase pure sine wave inverter. Finally, at the inverter output, an LC low-pass filter is used to improve the response and obtain a better sinusoidal AC waveform with lower THD.

The developed work in this paper focuses on the optimal integration of rechargeable electric vehicles into the smart grid. Indeed, an optimization control is proposed to improve the dynamics and the response of these vehicles by adjusting all the parameters of their regulators during participation in the both concepts: vehicles to grid and grid to vehicles. The suggested approach is performed using the Online multi-objective Particle-Swarm-Optimization (PSO) algorithm. Simulation results obtained by "Matlab Simulink" will be presented to show the feasibility of this studied approach.

This work presents a contribution to the analysis of the behavior and the control of the performance of a microgrid consisting of renewable photovoltaic and wind emergy sources equipped with storage batteries intended to supply an industrial load. To ensure better management of the system, energy models have developed to determine the power that sources can provide under given weather conditions. Management strategies have been adopted for the different scenarios to highlight role of the use of the storage means in connected mode for this system under the MATLAB/ SIMULINK environment. This study allowed us to guarantee the uninterrupted power supply as the optimal operation of the microgrid, and the safety of the battery. Technical reliability study was developed under a dynamic simulator based on the LPSP power loss concept, allowing us to size and select the best configuration.
