primary and widely in use computed tomography (ct) dose descriptor is a volumetric ct dose index (ctdiv) that is usually measured by a pencil ionization chamber with active length of 100mm and polymethyl methacrylate (pmma) phantom. ctdiv depends on scan parameters such as mas, kv, collimation, tube rotation time but is independent of patient’s size and shape. for the purpose of a good estimati...

Enzyme kinetic parameters have been estimated using MATLAB software via the Wilkinson nonlinear regression technique. The MATLAB script file written to implement this technique is short and very straightforward. Several software tools are commercially available for this purpose, with many graphical user interface (GUI) features. A routine use of these packages might offer immediate satisfaction...

conclusions these studies will enable physicians to diagnose and follow up many cardiac diseases when this software is interfaced within echocardiographic machines. results myocardial fibers initiate from the posterior basal region of the heart, continue through the left ventricular free wall, reach the septum, loop around the apex, ascend, and end at the superior-anterior edge of the left vent...

This report describes a software package for optimal control of a nonlinear system with flow variant time delay. The software was developed for control of a solar plant in Seville, Spain, and is tailored to this application. The optimization is performed using an algorithm with gradient based minimum search. PREREQUISITES This report only describes the software. The user is assumed to have a wo...

This paper describes a Matlab based software environment for the estimation of dynamic systems. It has been developed primarily as a vehicle for profiling novel approaches relative to existing methods within a common software framework in order to streamline comparisons. Key features of the toolbox include simplicity of use (particularly via automated entry of unspecified values) and the suppor...

The true costs of high performance computing are currently dominated by software. Addressing these costs requires shifting to high productivity languages such as Matlab. MatlabMPI is a Matlab implementation of the Message Passing Interface (MPI) standard and allows any Matlab program to exploit multiple processors. MatlabMPI currently implements the basic six functions that are the core of the ...

The aim of this work is to show the application of computer software to solve complicated real life engineering problems. The software used is MATLAB where a code is written after the theoretical derivation of the governing equations. The application of MATLAB is on mechanical engineering fluid mechanics unit. The application is for the selection of the best arrangement of pipes series/parallel...

Heart disease is a major cause of morbidity and mortality in the modern society. Almost 60% of the world population fall victim to the heart disease. Although significant progress has been made in the diagnosis and treatment of coronary heart disease, further investigation is still needed. Data mining, as a solution to extract hidden pattern from the clinical dataset are applied to a database i...
