Modeling of Power Quality Disturbances using Parametric Equations in MATLAB- The aim of this paper is to present modeling of power quality disturbances based on parametric equations. Parametric equations are considered for transients, short-duration voltage variations, harmonics, voltage sag with harmonics...
Currently, I use the equations of x and y to create [X, Y] = meshgrid(x,y) but I have no idea how to relate Z to these when the parametric forms x, y, and z are all functions of a radius (r) and sin function. For example, x = 4rsinΘ, y = rcosΘ/2, z = r^2 ...
TheSum of SineandFourierfits are particularly sensitive to starting points, and the optimized values might be accurate for only a few terms in the associated equations. Specify Fit Options at the Command Line Create the default fit options structure and set the option to center and scale the da...
1.(Mathematics) one of a number of auxiliary variables in terms of which all the variables in an implicit functional relationship can be explicitly expressed. Seeparametric equations 2.(Mathematics) a variable whose behaviour is not being considered and which may for present purposes be regarded as...
This finds b and a in by creating a system of linear equations and solving them with the MATLAB® \ operator. Here A(w(k)) and B(w(k)) are the Fourier transforms of the polynomials a and b respectively at the frequency w(k), and n is the number of frequency points (the ...
To be able to conduct a parametric study to develop design equations, a complete three-dimensional verified finite-element model of culverts is essential... AK Garg,A Abolmaali - 《Journal of Transportation Engineering》 被引量: 35发表: 2009年 Improved Load Distribution for Load Rating of Low...
was derived using the equations described by Gunn et al. 1997 [25]. These values were further adapted to obtain the optimal settings by comparing the regional parametric estimates to the reference standard. Furthermore, the weighting factors used in the implementation of the parametric methods were...
In order to evaluate system performance under different conditions, Eqs. (4-b), (5-b), (6-c), (9-b), (10-b) were solved numerically. For this purpose, a code was developed based on the finite difference scheme in MATLAB software. The flowchart of solving the governing equations has...
These models typically incorporate mathematical equations representing the electrical activity in different regions of the heart and the propagation of the electrical signal throughout the cardiac tissue. By adjusting the model's parameters and simulating physiological conditions, realistic ECG signals can ...
It can also be used when the resulting geometry is based on equations or maybe too complex. This program offers complete analysis, design, and manufacturing capabilities on a scalable, integral platform. The capabilities include rendering, surfacing, solid modeling, data interoperability, simulation, ...
