2008 Engineering Day Presentation

At the request of those who were present on February 16, 2008 during the Cedarville University Engineering Day, I have attached the powerpoint presentation that I gave. You may download this presentation in two formats, a powerpoint slide show, or as a PDF document. The PDF document has all of the information minus the animations and video clip. The Powerpoint slide show is complete.

Education:

• I received my Ph.D. from The Air Force Institute of Technology under a Dayton Area Graduate Studies Institute (DAGSI) scholarship. My declared area of specialty was Digital Signal Processing Computer Architectures, in which I studied the hardware (VLSI) implementations of signal processing algorithms.  My dissertation, "Approximation and Optimization of an Auditory Model for Realization in VLSI Hardware"  sought to design an applications specific integrated circuit which would directly implement the DSP algorithms used in The Auditory Image Model.
• From this research I presented a paper at the 42nd Midwest Symposium on Circuits and Systems in Las Cruces, NM in August 1999. The paper, which received the "1999 Myril B. Reed Best Paper Award" was titled "A Fast, Low-Power Logarithm Approximation with CMOS VLSI Implementation." This paper can be found in the proceedings of this conference.
• I also received my MS in Computer Engineering from The Air Force Institute of Technology (AFIT) in 1992. Thesis title: "A Single-Chip 2Kx8-Bit Pipelined Digital RF Memory Using 2um CMOS VLSI Technology" I presented a portion of this work at the 6th Annual IEEE International ASIC Conference and Exhibit" in Rochester, NY in 1993. The paper titled "A 2K x 8-bit Single-Chip Digital Radio Frequency Memory" appears in the proceedings of this conference.
• I received a BS in Engineering (BSE) with the Electrical Option from Wright State University Dayton, Ohio in 1988. I have returned to WSU each of the last five summers to teach a course in the VHSIC Hardware Description Language (VHDL).

Biography:

Born and raised in Bellevue, Ohio. Past employment for the US Air Force includes 3 1/2 years as a Flight Simulator Computer Technician (F4E), and 3 years as a laser systems engineer.  I have been on the faculty here at Cedarville University since January of 1993.

• Fortran Programming
• C-Programming
• Circuits
• Instrumentation
• Electronics
• Microprocessors
• VHSIC Hardware Description Language (VHDL)
• CMOS VLSI Design
• Electrical Machines Lab
• Computer Architecture
• Electrical Engineering Senior Design

Interests:

• Solid State Electronics
• VHDL Modeling & Instruction
• Auditory Modeling
• VLSI Design
• Engineering Education.
• Computer architectures and programming.
• Digital Logic system design, including VLSI applications.
• The Linux Operating System (I'm a Slackware user).

Just for fun...

Here is an “Amazing Maze” program I wrote for the Windows environment :  Maze3D.exe This newest version (created in March of 2007), provides two different playing modes: a traditional top-down 2D mode, and a new "mouse in the maze" 3D view. It also sports my new maze generating algorithm which makes better mazes. I wrote this program as a way to learn C++ programming for the Windows operating systems. This latest build was done using the (free) DEV C++ design environment.
I am making this program available for anyone to download, play, and share. All I ask in return is that you do not modify the code, or attempt to make a profit from distributing it. This is a work in progress, there are known "undocumented features" that you may find annoying. If you download it and play with it, you assume full responsibility for any adverse effects it may have on your mental health or your computer. Enjoy!
