Life Cycle Of A Pumpkin

The code computes the velocity profile for the vertical laminar flow of a Bingham fluid down a wall. As expected the profile is flat near the surface of the liquid film. In fact, we have a zero velocity gradient only when the shear stress is large enough (superior to tau0). This behaviour is...

Equations of motions of a Cessna are modelled in this matlab GUI. Cessna levels of to a steady level flight at 10.5 kms. Four plots show (a) Alt Vs Time. (b) Alt Vs G. (c) Vel Vs Tim. (d) Flight path angle Vs Time. Other plots like Range, Ceiling, Flight Path Angle can be obtained using the GUI...

The standard problem of a Two Link Manipulator is developed both kinematically and dynamically. It is then controlled to trace a rotated ellipse. The non-linear terms (like gravity/inertia etc.) are exclusively canceled out in varying degrees and the performance studied.This file was created as a...

The velocity and shear stress versus radial position are obtained for the laminar flow of a power-law fluid in a pipe. Pipe radius and applied pressure gradients can be set by the user. If you choose a power-law exponent, n, equal to 1 then a Newtonian fluid is recovered. Dilatant and...

Design of a robust digital controller with PPR toolboxThis script shows the basic steps for the "digital two degrees of freedom controller" (2DOF) design with the PPR toolbox.The illustration of our methodology is based on a difficult plant control. To get a 2DOF controller, only 2 "high level"...
