R. W. Hecht, "Algorithms For Min-Max Problems In Hilbert Spaces," Report R-548, Coordinated Science Laboratory, University of Illinois, Urbana, Illinois, January, 1972.
The problem considered is the minimization of a functional in Hilbert spaces, where the functional being considered is the maximum of a set of N functionals for each point in the Hilbert space. Two algorithms are presented. One is a gradient, or steepest-descent, method. The other is a Newton-Raphson method. It is shown that the two algorithms are to be used together. The steepest-descent method is to be used first and then the Newton-Raphson method. To use the Newton-Raphson method, convexity is assumed. Both the theoretical and the numerical aspects of the algorithm are discussed.

1991-1992 Contracted with the United States Navy to design an advanced radar antenna.
1988-Present Associate Professor in the Department of Electrical and Computer Engineering at California State University Fresno, Fresno, California. Teaching undergraduate Electrical Engineering classes and laboratories. Subjects taught include: Electromagnetic Field Theory, Signals and Systems, Control Theory, Communication Theory, and a Transmission Line and Microwave Laboratory.
Summer 1989 Consultant for Integrated Sciences, Tulsa, Oklahoma. Designed a microwave system which simultaneously and independently measures both electric (E) fields and magnetic (H) fields and their relative phases. This system operates from 10 MHz to 10 GHz.
1979-1988 Staff Engineer in the Guidance and Performance Analysis
Department, Missile Systems Group, Hughes Aircraft Company, Canoga Park, California. Responsible for modeling the radar and the threat environment for use in three and/or six degree of freedom (6-DOF) trajectory simulations and for providing hardware and/or software solutions to a variety of threat situations. Worked on AMRAAM, Phoenix, and WASP missiles. Some typical assignments included modeling glint for AMRAAM and WASP and developing an algorithm to minimize its effects. Developed a radar clutter model for use in the three and six DOF's. Designed a Kalman angle tracker for Phoenix missile. Designed a hardware and software invention to solve a secret threat scenario.
1977-1979 Assistant Professor in the Department of Electronic and Electrical Engineering at California Polytechnic State University, San Luis Obispo, California. Taught undergraduate and graduate Electronic Engineering courses and laboratories and was student course advisor and senior and graduate student project advisor.
1974-1977 Assistant Professor in the Department of Engineering Technology at Virginia Polytechnic Institute and State University, Blacksburg, Virginia. Developed and taught junior and senior Electrical Engineering Technology courses and laboratories and was student course advisor and senior project advisor.
1973-1974 Control Systems Analyst at Sargent and Lundy Engineers, Chicago, Illinois. Developed mathematical models of the various analog control systems used in nuclear and fossil fuel electric power plants. These models were part of a transient analysis program of a power plant. Also, performed qualitative analysis of malfunctioning control systems.
1972-1973 Postdoctoral Fellow at the Energy and Environmental Systems
Division, Argonne National Laboratory, Argonne, Illinois. Worked on the Argonne Airport Vicinity Air Pollution Program. Developed major modifications to Gaussian Plume Dispersion Model used in this project. Evaluated the model using data gathered at both O'Hare Airport, Chicago, Illinois, and Orange County Airport, Orange County, California. Using this verified model, analyzed various pollution control strategies to assess environmental impact in the airport vicinity.
1968-1972 Research Assistant in the Coordinated Science Laboratory,
University of Illinois. Developed an algorithm for solving minimum-maximum problems in Hilbert spaces. Using this algorithm, found the optimal solution to several problems where all the system variables could not be determined.
1967-1968 Research Assistant, Department of Computer Science, University
of Illinois. Worked on Fortran IV Compiler.
1965-1967 Research Assistant, Department of Computer Science, University
of Illinois. Worked on Time-Sharing System for Illiac III, a university-built computer.
Summer 1965 Engineer at Sargent and Lundy Engineers, Chicago, Illinois.
Worked on plans for a Transmission Line Switchyard.
While teaching at California State University, Fresno, Dr. Hecht contracted with the Navy to design an advanced radar antenna. His final report is :

While teaching at California State University, Fresno, Dr. Hecht consulted for a small company during the summer of 1989, namely: Integrated Sciences, formerly of Camarillo, California and presently Tulsa, Oklahoma. He designed a microwave system which simultaneously and independently measures both electric (E) fields and magnetic (H) fields and their relative phases. This system operates from 10 MHz to 10 GHz. Dr. Hecht documented this work in Appendix 7 of the final report to Oak Ridge National Laboratory.
