Cloth modeling
Cloth modeling – Wikipedia, the free encyclopedia.
Or – do a search for cloth physics.
This is very similar to the spider on a web project idea.
Model a non-linear pendulum that has magnets.
Check the video below. It is a simple pendulum, but reacts to magnets near the base. A non-linear problem to be modeled with RK – but not too difficult. http://en.wikipedia.org/wiki/Force_between_magnets#Magnetic_dipole-dipole_interaction
Implement an adjustable step-size RK algorithm for animations
The animation system at http://lpsa.swarthmore.edu/Animations/ uses a fixed step size animation. Alter the code to use a variable step size.
Use an animation system (see below) to develop animations for homework problems.
Use the animation system (http://lpsa.swarthmore.edu/Animations/) developed by a student a few years ago to develop animations for some of the homework problems.
Use simulink and MATLAB together to simulate a system (and animate it).
Use simulink and MATLAB together to simulate a system (and animate it). You could also do it all in MATLAB. The coupled pendulum system comes to mind.
Simulate this non-linear system with spinning magnets.
Simulate the system shown using Runge-Kutta (it is nonlinear, but not too complex). http://en.wikipedia.org/wiki/Force_between_magnets#Magnetic_dipole-dipole_interaction
Explore Z-Transforms
Z-Transforms are related to the Laplace Transform, but are used for discrete time systems (i.e., when a computer is used to sample a signal). This would be more research then physical.
Javascript tool for demonstrating some principal from class.
Develop an interactive JavaScript tool for demonstrating some principal from class. … pole locations and step response? pole locations and Bode Plot? animating the Runge-Kutta process?
Use Audio Analyzer to Demonstrate Convolution
It would be very nice to have a MATLAB gui that makes the audio analyzer output a series of impulses to a circuit and then have software that would add up the delayed and shifted impulse responses to create the output due to an arbitrary input. This is ambitious, but if you want a very software (MATLAB) intensive project – this might be it.
