Dr. Nelson's knowledge and expertise stem from his long career and experiences which include co-founding the University of Nebraska's Computer Science Department in 1964. Through his experiences, Dr. Nelson has become a pioneer in the field of computer science and communication.

With his leadership and stability, Dr. Nelson has led some of the largest and most successful projects at the federal, state and industry levels. He continues to pioneer new technology at i2rd.


            This site contains three texts.  All are somewhat related in that the three texts contain elements of logic and simulation and all were the result of needing a better text for teaching a particular subject.  From a creation point of view, the first text was Switching Theory and Logic Design.  The second was Fundamentals of Load Projection for Public Utilities.  The last, and most dear to my heart, is Simulation – Understanding Numeric Methods.

            All texts assume that the reader has knowledge of most of the material but is seeking a better understanding of the text.  Before you start, however, I would caution you that there may be holes in your understanding and in my understanding as well.  I am reminded of a time when I was working on my Ph. D. degree, and I was asked to develop an analog computer program for ray tracing.  I was provided with a sheet of the equations which one would think should be sufficient.  However, although I had built an analog computer and used it a great deal, the equations were a mystery to me.  So I went to the library and began searching for something to help me understand.  I didn’t keep track of the books and papers I read, but it was a large number.  Nowhere could I find the clues that were necessary for me to understand what I had to do.  I found older and older references to the material, but never the answer – until I read a paper by James Clerk Maxwell (yes, the Maxwell of Maxwell’s Equations).  He wrote so simply and completely in his paper, that it all fell into place.  So my advice to young students is to persevere in your reading. You will find someone who knows what they are talking about.  And, oh yes, I was able to program the analog computer to do ray tracing.  (I couldn’t be a part of the actual programming because that was all done within a classified area, but I was told that it worked.)

            Everything you need to know undoubtedly isn’t in here.  But there are some things in each book, but especially in the Simulation book, that I have not seen written elsewhere.
