Data Analysis using Python

1. What does popt and pcov mean?  popt is an array with estimated values of coefficients in the equation ax^2+bx+c popt stores the value of the parameters a,b,c pcov is a covariance matrix. It has the estimated values of covariance parameters of      popt, which is used to find the deviation of parameters…

                                             NASA File Parsing  File Parsing in MATLAB: In general, the term \"parsing\" refers to MATLAB reading an m-file (script or function) and translating…

The Genetic Algorithm Theory: The genetic algorithm is the evolution theory proposed by Charles Darwin. It is a random based classical evolutionary algorithm. GA solves any function to find the optimum values based on requirement of the function. MatLab provides an inbuilt function that actually helps to do the genetic…

The following question is done by using MATLAB software clear all close all clc % inputs l1 = 1 l2 = 0.5 theta1 = linspace(0,90,40); theta2 = linspace(0,90,40); ct=1; for i=1:length(theta1) THETA1=theta1(i); for j=1:length(theta2) THETA2=theta2(j); x0=0 y0=0 x1=l1*cosd(THETA1); y1=l1*sind(THETA1); x2=x1+l2*cosd(THETA2);…

The following programs is done using Octave    1. calculating the drag force against a cyclist, where Velocity vs Drag force is plotted.   Description 1 :  In this problem, Typically, the drag coefficient of a cyclist ranges from \approx0.6 for a streamlined time-trial position to…

This problem is solved using MatLab. simulation of a simple pendulum using MatLab.   Description: Step 1: In this, the main inputs required for the simple pendulum such as damping coefficient, acceleration due to gravity, mass of the ball and length of the string and later on given the values of angle theta ranges…

An Otto cycle is an idealized thermodynamic cycle that describes the functioning of a typical spark ignition piston engine. It is the thermodynamic cycle most commonly found in automobile engines. Processes : Process 1–2 is an adiabatic (isentropic) compression of the charge as the piston…
