Supervised Learning - Prediction Week 3 Challenge

  Make a Simulink model of Doorbell using solenoid block with the following details: To create a doorbell model using a solenoid block we need to import both the electrical and mechanical systems together. The list of items used for making a doorbell model: Pulse generator Simulink to ps converter scope…

1.  PROS CONS It is highly accurate Its speed is low It can handle many features It requires more time to process Works well even in small sets Separates only 2 classes     2. Applying SVM from sklearn import datasets, linear_model import numpy as np import pandas as pd import seaborn as sns import matplotlib.pyplot…

Aim: Derive derive both the conservation and non-conservation forms of the governing equations and sovle them using the MacCormack's technique. Also determine the steady-state temperature distribution for the flow-field variables and investigate the difference between the two forms of governing equations by comparing…

Simulation of Flow through a pipe in OpenFoam: Aim: To simulate an axi-symmetric flow by applying the wedge boundary condition. Do a transient or steady state simulation and you will validate your results with the Hagen- Poiseuille's equations for the fully developed flow. In this challenge you will simulate…

Write code in Matlab to automate the generation…

AIM:  To simulate  an incompressible-laminar-viscous flow through the backward facing step geometry. Also should perform a transient simulation. The solver can be chosen based on the described physics of the flow. Procedure: Create  the following geometry and divide them into 5 segments as explained…

1.pfa    2.  Mean absolute error Mean square error     Sum of absolute differences between target and predicted variables Sum of squared differences between target and predicted variables Error is minimal as there is no square Error is high as there is square especially if e >1    …

1.Ans   Calculating the four business moments: A)Calculating the Mean of the problem: P(i)*X(i) = (0*0.35)+  (1*0.25)+(2*0.15)+(3*0.15) + (4*0.10) = 0+ 0.25 +0.3+0.45+0.4 =1.4 B). Variance Sum(Xi-Mu)^2 *P(X)  = (0-1.4)^2 *0.35 +((1-1.4)^2)*0.25 + ((2-1.4)^2)*0.15 + ((3-1.4)^2)*0.15 + ((4-1.4)^2)*0.10 …

1. Ans: The difference between variance and sample variance relates to calculation of variance. If a variance in the sample is calculated we are neglecting the lack of information regarding the population size. So the sampe variance will definitly be greater than the variance of the population size. To compensate…

  Objective: To solve the 2d heat conduction equation by using the point iterative techniques which includes the use of following the implicit methods Jacobi Gauss-seidel Successive over-relaxation The boundary conditions are as follows Top Boundary = 600 K Bottom Boundary = 900 K Left Boundary = 400 K Right Boundary…

Objective To derive the fourth order approximation for the second order derivative by following methods: Central difference Skewed right side difference Skewed left side difference Taylor table for central difference:     From the above Taylor table, equations extracted are a + b + c + d + e = 0 -2a-b + d + 2e…

File Parsing of NASA thermodynamic data Introduction In this report we are going to explain how to parse the thermodynamics data that has been provided to us using MATLAB. Also how we are going to generate plots between Cp, S and H for each and every element. Steps for creating File Parsing of NASA thermodynamic data using…

Steps for creating general algorithm MATLAB program1. First, erase and close the previous data keyed in by typing the clc, clear all and close all.2. Input the X and Y coordinates by mentioning the limits and the number of values to be taken inbetween them using linspace. Also mention the no of cases/iterations for the…

Pendulum angular displacement and velocity calculationIntroductionA pendulum is a kind of weight called as a bob which is suspended freely to swing freely. When the pendulum is given a sideways thrust from inertia or its equilibrium position is accelerate back and forth with some velocity and displacement. In this report…
