Extensive experience in the computer simulation of physical systems. Developed theoretical models concerned with properties both mechanical and electronic. Additionally, taught the experimental segment of a computational physics course (data acquisition and processing) at both the undergraduate and graduate level.
Extensive experimental physics experience associated with both pure and applied physics. Doctoral and early postdoctoral work was involved with nonlinear acoustics via cryogenic measurements of ultrasound. Later work also has involved nonlinear phenomena, to include chaos and complexity. Developed a variety of novel instruments with which to do these studies, and patented capacitive sensors have been incorporated into commercial products, some of which have received widespread acclaim.

"Capacitive Sensors for Nano-Positioning and Methods of using the same", (with Scheng-Chang Lee), U.S. patent pending.
"Linear rotary differential capacitance transducer"--U.S. Patent No. 5,038,875.
"Symmetric Differential Capacitance (SDC) Transducer employing cross coupled conductive plates to form equipotential pairs"--U.S. Patent No. 5,461,319.
Concerning the SDC patent:
(1) A variety of instruments have been developed around this sensor. These include the "Computerized Cavendish Gravitation Balance" which is sold by Tel-Atomic Inc. and also Central Scientific Company. This state-of-the-art instrument is the heart of one of the first six NASA Breakthrough Propulsion Physics grants.
(2) A miniaturized accelerometer based on the SDC technology (mesoscale using PC boards) was developed and tested by Auburn University's 'Leap' (Laboratory for Electronics Assembly and Packaging).
(3) An array of SDC type was used in the 'Electric Power Assisted Steering' prototype built as a senior design project by Mercer Mechanical Engineering students. (2001).
(4) SDC sensors employing LABVIEW algorithms in place of traditional Phase Sensitive Detector electronics are being used to measure strain in pig tissue samples as a function of temperature. The project is of importance to heart valve replacement in humans and is the senior project work of three Mercer Biomechanical Engineering students. (2002)
(5) SDC pressure sensor used in a "Respiration monitoring device to aid in the trreatment of obstructive sleep apnea", for Dr. Larry Tilley, Dentist, Calhoun, GA--by Mercer Engineering students Reuben Bailey, Ben Johnson & Stephen Spalding. (2006).

BRIEF DESCRIPTION OF WORK WHILE IN INDUSTRY:
Characterized engineering (missile) systems, particularly those that use electro-optical sensors via dynamic simulation. Effectiveness vs system variables quantified statistically, often by monte carlo technique.
Modelled the infrared signatures of satellites, including dynamic thermal solutions for components as influenced by environment. Personally developed an imaging technique which was responsible for over a million dollars in contract awards after industrial competition.
The algorithms which followed were used in the only U.S. satellite intercept of 13 Sep. 1985, and also to assess the danger of COSMOS 1402 in 1983; for which a rare commendation from the Air Force Deputy for Space Defense Systems was received.
MISCELLANEOUS ADDITIONAL Univ. of Mississippi ACTIVITIES:
Developed optical systems, including a high power carbon dioxide laser. Fabricated vacuum systems for use in evaporation and sputtering. Built thin film dielectric mirrors for interferometric studies of acoustical phenomena. Engaged in cryogenic studies concerned with nonlinear acoustics. As noted in some of the communictions listed earlier: worked with a shock tube in a study of a capillary medium's capability to attenuate shocks generated by a pulsed laser (sponsored by the dept of mech. engr.). Developed a method of measuring number density of particles suspended in a fluid by the scattering of ultrasonic radiation. Engaged in physiology research aimed at a better understanding of cardiac output dynamics. Used instrumented subjects to measure arterial pulse velocities as a function of oxygen uptake.
The total of grants and contracts awarded as the result of Peters' work is approximately $1,800,000. An unsolicited grant from Ford Motor Company was accompanied by a letter to the President of TTU from the Manager of Electronic Materials and Devices which included the statement: "We find the work of Dr. Peters most interesting...."
PERFORMANCES AND EXHIBITIONS
"Artwork from a pendulum" was one of the features at the TTU College of Arts and Sciences homecoming, 1988. The support constrained pendulum used to produce this artwork also was used to produce the departmental undergraduate poster and a student teeshirt.
The symmetric differential capacitive (SDC) transducers invented by Peters have been and continue to be incorporated into physics demonstration and laboratory equipment sold by TEL-Atomic Inc., Jackson, Michigan and Central Scientific Company, Chicago.
