This review-paper focuses on the latest development of modelling and control of grid connected photovoltaic energy conversion system. Modelling of photovoltaic systems include modelling of SPV array, power electronics inverter/converter based on MATLAB/SIMULINK. This present control algorithm of a three-phase and single phase grid-connected photovoltaic (PV) system including the PV array and th...

Many gene selection algorithms have been applied in gene expression data analysis successfully. To solve different developing environments of these toolkits, such as rankgene (Su et al., 2003), and mRMR (http://research.janelia.org/peng/proj/mrmr/index.htm), perform data analysis and make algorithm comparison more flexible, we have developed a software package LIBGS including: 1) Seven new gene...

This article presents a few different methods to present a passive walker model in Adams MD R3 software and compares their simulation results to a walker model built in Matlab software. The discontinuous Matlab simulator applies manually entered mathematical equations to describe system dynamics while the Adams simulation software creates the dynamic models automatically. In the Adams simulator...

─ This paper presents a new method to model inhomogeneous media in commercial electromagnetics software, especially FEKO. In this method, the inhomogeneous medium is fragmented to some homogeneous pieces. If the size of these pieces is chosen correctly, then the electromagnetic behaviors of them and inhomogeneous medium are the same. Since creating these homogeneous pieces in FEKO manually is v...

Software estimation accuracy is among the greatest challenges for software developers. Software development effort estimation is one of the most major activities in software project management. A number of models have been proposed to make software effort estimations but still no single model can predict the effort accurately. The need for accurate effort estimation in software industry is stil...

High resolution multichannel ECG measurement is necessary prerequisite for advanced diagnostics of various cardiovascular diseases. Special multichannel electrocardiograph ProCardio-8 was developed to obtain ECG signals with desired quality. The system is conceived as a virtual instrument with an external intelligent measuring unit connected to a host PC running dedicated application software. ...

In this paper, we have implemented Radar Transmitter-Receiver. Direct Sequence Spread Spectrum BPSK is chosen as modulation method because of its numerous advantages like accuracy of ranging, sensitivity, targetseparation, accuracy of power-estimation, interference suppression, etc. We have employed this scheme using MATLAB Simulink which is a software package for modelling, simulating, and ana...

This paper focuses on methods of interfacingLabVIEW with MATLAB package for applicationswhichneed extensive computation as well as automation and control. It aims to integrate MATLAB and LabVIEW together,and develop a calibration software for frequency generators supporting the IEEE-488 bus standard. Different approaches have been explored that can be used to combine the data acquisition featur...

There has been an emerging open source data mining software development in current times. In this work I carry out an empirical study to compare the performances of open source and commercial data mining software. The results clearly reveals that before and after data preprocessing of the two NASA datasets used in this work, commercial data mining software (MATLAB) outperforms open source data ...

Through investigating intelligent diagnosis method of Computational Intelligence (CI) and studying its application in fault feature extraction, a gear fault detection and Virtual Instrument Diagnostic System is developed by using the two hybrid programming method which combines both advantages of VC++ and MATLAB. The interface is designed by VC++ and the calculation of test data, signal process...
