In this project the student creates an interactive web-demo application using web-mathematica (http://www.wolfram.com/products/webmathematica/). Plots of 1D signals that are constructed with B-splines are created and displayed along with the weighted shifted basis functions. Interactively derivatives or integrals are computed and also displayed as a function of the derivatives or integrals of the B-splines. The student should have excellent programming skills (IC section) and be familiar with HTML5, java, javascript. Additional experience with mathematica is a plus.
