Zillow Value v1.0a
This PHP script demonstrates how WirzBrothers zestimate.php can be used to find the Zillow Estimated Value of a property. There are many other scripts out there that accomplish this, however, WirzBrothers has exploded the xml class provided by the Zillow Application Programming Interface (API) in order to mine the specific information we desire - in this case the fair market value (as calculated by Zillow) of the property. Now we have provided a simple PHP function which uses the WirzBrothers API which uses the http://www.wirzbrothers.com/zestimate.php feature.
Google Page Rank Calculator
This excel Add-in will turn a URL into its corresponding page rank for the selected cell.

Christopher Wirz's Resume
Chris's resume containing college through current position.
Multi-Input Modelingusing Sparsity Constraints with Global-Local Approximation
This is my Masters of Science Thesis/Project detailing a novel systems identification approach. In this project, we take a system with unknown dynamics and utilize a dictionary function to develop a prediction for future states. I demonstrate this principle on 1D functions, 2D functions, and n-D functions - modeling sensor input, terrain maps, and the stock market.
