Experience

  • Multi-Input Multi-Output Modeling using Global-Local Approximations with Sparsity Constraints" (Development)
    http://www.wirzbrothers.com/chris/2008-wirz-ms-thesis.pdf

    This Masters of Science Thesis, under the direction of Dr. Puneet Singla, details a novel systems identification approach. In this project, a system with unknown dynamics utilizes a dictionary function to develop a prediction for future states. This principle is demonstrated using 1D functions, 2D functions, and n-D functions to model sensor input, terrain maps, and the stock market.

  • US Patent 20120318294 (Other amazing things)
    http://www.wirzbrothers.com/chris/us20120318294a1.pdf

    The core un-blocking roller brush is used in the preparation of low-observable aircraft sub-structures. This brush allows for the application of low-observable coatings as well as composite layup.

  • US Patent 20120321800 (Other amazing things)
    http://www.wirzbrothers.com/chris/us20120321800a1.pdf

    The Core Striping Mechanism applies a load-line to honeycomb core, which is an important sub-structure of low-observable air crafts. Using a series of nozzles guided along a rail, a line is easily developed, preventing the need for masking and excessive touch-labor.
