EMPLOYMENT:

Sparta Inc. (2002- present): Research Engineer @ Edwards AFB, CA
Provide code development support for the U.S. Air Force Research Laboratory, Solid Rocket Propulsion Branch (AFRL/PRSB). Responsibilities include, but are not limited to, code development and support of the various in-house engineering software tools related to the focus of PRSB (Motor Branch), programming support of the Automated NDE Data Evaluation System (ANDES) 1 and 2 designed for the detection of propellant flaws in solid rocket motors, and update, modification and refinement of any related documentation.

Accomplished projects:
• Integrated Part Evaluation System (IPES) port: Converted a system of software routines from SystemV Unix to BSD Unix. This is a system of software modules designed to detect and process solid rocket propellant flaws obtained from computed tomography data. Tasks included the conversions from AVS4 to AVS5.
• Ultrasonics Module port: Converted a series of ultrasonics data input/processing modules from IPES residing on a BSD Unix platform (Sun) to the MS Windows operating system. The porting process included conversion from AVS 5.1 (Unix) to AVS/Express 5.1 (Windows).
• Ultrasonics Data Processing in ANDES/2: This in-house project was to develop ultrasonics NDE processing capability into ANDES/2 which originally focused on X-ray CT only. Test and verification of all software coding tasks were required and implemented in all levels. This served to illustrate the NDE incorporation capabilities of ANDES/2 to process other than X-ray CT data and was demonstrated to various interested parties.

Current project:
• Provide software support for ANDES/2 system: Correct, test, and verify the ANDES/2 flaw detection networks (algorithms) for solid rocket motors. Various code segments and modules are being modified to meet U.S. Air Force inspection criteria for these motors. Whereas ANDES/2 working very well with ICT X-ray CT data, there are problems with HECT2 X-ray CT. The goal is to have the automated ANDES/2 inspection results in agreement with what visually inspected for the HECT2 CT scans of these motors.
