The traditional user of scientific computing prefers to use well proven routines that are recognized by the international scientific community. Among the well-known collections are IMSL, NAG and LINPACK. However, a direct solution method should be used in the case of dense non-structured matrices. If, in addition the co-efficient and the right hand side are ...

The Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT) play vital role in signal processing. It is often used in many communication systems. The proposed paper produces realization of N – bit FFT processor using Radix-4 algorithm. Radix-4 FFT processors have 3N/4 log4N complex multiplications and 3N log4N complex additions. N-bit processor contain ...

The global electrical energy consumption is steadily rising and consequently there is a demand to increase the power generation capacity. A significant percentage of the required capacity increase can be based on renewable energy sources. The need for a cleaner environment and the continuous increase in power demand makes renewable energy production, like solar and ...

Voltage sag caused by the short circuit fault in transmission and distribution line. In this paper, voltage sag due to power system faults such as three-phase-to-ground, single-phase-to-ground, phase-to-phase and two-phase-to-ground are created in transmission line model for generation of different types of voltage sag. This paper describes a methodology for voltage sag generation using Matlab/Simulink. ...

In this paper, the authors focused on modelling and simulation of grid connected photovoltaic system. This paper presents a fuzzy logic control based maximum power point tracking approach to enhance the efficiency and robustness of the solar PhotoVoltaic (PV) power generation and establishes a dynamic model of grid-connected PV system by Matlab/Simulink environment which reflect ...
