Raw data is commonly presented in graphical form in published literature. Often authors may be in need to source data from such publications. The raw research data is normally not available to fellow researchers due to non availability of data itself or lack of interest of the author to share the data. Presently many software tools are available for extracting the data from the graphs. But the user...
Flight control law software have errors. Some are found during the extensive testing and certification process and others pass through causing accidents. The testing of flight control software indicates that the code and the model match. But it is very difficult to ensure if the model was correct in the first place. Model checkers like Mathworks Simulink Design Verifier check the models against formally...
A toolbox for model-based fault detection and isolation (FDI) has been developed in the MATLAB/SIMULINK environment. It includes methods relying on analytical or qualitative models of the supervised process. A demonstration of each approach can be performed on a simulation of either a three-tank system, a cocurrent or a countercurrent heat exchanger. The results are displayed in a common format, which...
The possibility of non-linear programming method for the analysis of dissipative systems with con centrated parameters tained non-reactive elements and the use of this approach for the calculation of many arms of river channels with general purpose software tools for mathematical calculations (MathCad, MatLab etc.)
This paper describes a new educational power electronics laboratory that was developed primarily to reinforce experimentally the fundamental concepts presented in a power electronics course. The developed laboratory combines theoretical design, simulation studies, digital control, fabrication, and verification of power-electronic circuits based on a set of hardware and software tools. The salient...
In this paper we present the implementation of a parallel searching algorithm, which is used for the insetting procedure in cartography. The calculation time of the above procedure is very long due to the fact that the datasets in cartography are maps with large and very large resolution. The purpose of this proposal is to reduce the calculation time in a multicore machine with shared memory. The...
This paper critically reviews the electrical tree growth measurement techniques commonly employed. The paper continues, describing the development of a user friendly software tool using MATLAB. This tool quantitatively evaluates a host of electrical tree growth images using various techniques, including fractal index, width length ratio and intensity frequency analysis. The software methodology, associated...
Fuzzy Logic theory has been applied in various fields and technologies. One of the Fuzzy Logic application is to grade the agriculture produce based on its size. Currently, the grading is done based on observations and through experience. For further improvement, a high speed grading system using a Fuzzy Inference System is designed to grade the agriculture produce. In this research, a banana fruit...
This paper describes two software tools to determine the overall trend of network signals: Matlab and Excel. Their implementation is shown through several characteristic examples from network environment. The appropriateness of different types of trends is also discussed.
Engineering education has become increasingly reliant on more powerful software tools to assist in solving more complex problems. This paper presents examples of the application of Matlab and Simulink software to theoretical analysis and experiments in the course of Computer Control System. These examples include the dynamic behavior investigation of the experiment of computer control two-tank system...
An integrated and comprehensive model of a hybrid pixel detector has been developed by using Matlab and Simulink. Prior to this streamlined model, various team members (physicists, electronics and software engineers) used different software tools to separately simulate individual entities of the system. As a consequence, it was difficult to exchange and integrate the results, as well as to interpret...
Moving target detection algorithm is PC-based software programming method to implement. At present, with slow processing speed and small scope of application problems, this paper takes System Generator for the development tool, which is a system-level modeling tool developed by Xilinx Inc, and built a reconfigurable video detection algorithm of moving target in MATLAB/Simulink environment, which is...
Within the paper, the authors deal with electric substation ancillary services power consumption analysis. They are focusing on load curve numerical processing. A real case study is discussed, Timisoara 400/220/110 kV substation, the consumers being supplied from the autotransformer tertiary winding. The parameters specific to ancillary services load curves are computed using a software tool developed...
Input data for generating the grid can be obtained in various ways, by survey or from existing sources. While producing this paper, available topographic maps were used. The primary goal was to create a software platform and methodology that would be used for generating a DTM grid by using different methods of interpolation from the cloud of points. All mentioned above was done with the aim of recognition...
In order to solve the multiple supply chains design (MSCD) problem with two dimensional cooperation, a across-chain horizontal cooperation model with two supply chains is used in this paper. Through hybrid genetic algorithm and software tools Matlab & Lingo, the MSCD problem with two dimensional across-chain horizontal cooperation can be rationally solve. For illustration, a example test is utilized...
The use of FPGAs in data acquisition cards for processing purposes allows an efficient real time pattern recognition algorithm implementation. Using 13 JETs database waveforms an algorithm for detecting incoming plasma disruptions has been implemented. This algorithm is written in MATLAB using floating point representation. In this work we show the methodology used to implement the real time version...
A comparison between modelling and simulation methods in regard to model order reduction (MOR) in finite element (FE) simulation tools is presented. Two main software tools are taken into consideration: ANSYS Multiphysics 11 with its extension MOR for ANSYS 2.55 and COMSOL Multiphysics 3.5a with a model order reduction interface to MATLAB/Simulink. The results achived with both software packages are...
DSP topics such as software defined radio are more easily taught if appropriate demonstrations and laboratory experiences are provided. This paper describes a new, inexpensive software defined radio educational platform based upon MATLAB and the Texas Instruments C6713 digital signal processing starter kit. We describe the hardware and software issues and briefly describe recommended classroom use.
In this paper we present a toolbox enabling easy evaluation and comparison of different filtering algorithms. The toolbox is called Kalmtool 4 and is a set of MATLAB tools for state estimation of nonlinear systems.
