    Harmonics and switching frequency cause a major problem in power system. A novel harmonic elimination technique and low switching frequency in a three-phase pulse width modulation (PWM) inverter are proposed in this paper. This inverter is associated with a LC filter. The technique determines the commutation angles based by solving a set of nonlinear system equations. This commutation angles are d... View full abstract»

    Orthogonal frequency division multiplexing (OFDM) is a promising technique in the next evolution of the mobile telephony, However it suffers from peak to average power ratio (PAPR). It is a problem for broadcast engineers in many different applications. Non-linearities can cause severe out-of-band radiation when confronted with high PAPRs. Previous work has shown that the application of coding jus... View full abstract»

    This paper proposes a new upcoming model of real time location system (RTLS) to focus and track the exact location of real time objects in vicinity. Overcoming the limitations of size, power, attenuation of GPS & DGPS system, the active RFID tags can be easily affixed with objects. The TIA approach of distance calculation will minimize the errors occurred in RSSI method. Geographically fixed m... View full abstract»

    An adaptive nonlinear sliding mode controller combined with a field orientation scheme has been developed for the control of induction motor to achieve rotor angular speed and rotor flux amplitude tracking objectives. The inputs to the controller are the reference speed, the reference flux, the measured stator currents, the measured rotor speed, the estimated rotor flux, and estimates of the varyi...

    In this paper we propose a hybrid algorithm to optimize the structure of TSK type fuzzy model using back-propagation (BP) learning algorithm and non-dominated sorting genetic algorithm (NSGA-II). In a first step, BP algorithm is used to optimize the parameters of the model (parameters of membership functions and fuzzy rules). NSGA-II is used in a second phase, to optimize the number of fuzzy rules... View full abstract»

    The In this essay, we are going to design a medical expert system by using neural network. In order to test the system, we used the data in the intended bank e.g. BUPA liver disorders. We compare the operation of the system with parametric methods -like Bayesian decision making theory- and non parametric methods. By analysis of the data, we first discovered an undesirable field in the bank which c... View full abstract»

    This paper presents analysis, calculations, and modeling of weighted network reliability. Basic equations for the reliability evaluation are stated, and an algorithm presented for calculation of weighted network reliability and program written in FORTRAN language for implementing that. Reliability found for different both (weighted and unweighted) networks, and the results were compared. View full abstract»

    In this paper, a novel selective encryption image scheme based on JPEG2000 is proposed, which encrypts only the code-blocks corresponding to some sensitive precincts. In order to improve the security level we introduce the permutation of codeblocks contributing in the selected precincts. Symmetric encryption AES with CFB mode is used to encrypt swapped codeblocks. The idea of combining permutation... View full abstract»
