James A. Svoboda is an associate professor of electrical and computer engineering at Clarkson University where he teaches courses on topics such as circuits electronics, and computer programming. He earned a Ph.D. in electrical engineering from the University of Wisconsin, Madison, and M.S. from the University of Colorado, and a B. S. from General Motors Institute. Sophomore Circuits is one of Professor Svoboda's favorite courses. He has taught this course to 2500 undergraduates at Clarkson University over the past 21 years. In 1996, he received Clarkson University's Distinguished Teaching Award. Professor Svoboda has written several research papers describing the advantages of  using nullors to model electric circuits for computer analysis. He is interested in the way technology affects engineering education and has developed several software packages for use in Sophomore Circuits. Richard C. Dorf professor of electrical and computer engineering at the University of California, Davis, teaches graduate and undergraduate courses in electrical engineering in the fields of circuits and control systems. He earned a Ph.D. in electrical engineering from the U.S. Naval Postgraduate School, an M.S. from the University of Colorado and a B.S. from Clarkson University. Highly concerned with the discipline of electrical engineering and its wide value to social and economic needs, he has written and lectured internationally on the contributions and advances in electrical engineering. Professor Dorf has extensive experience with education and industry and its professionally active in the fields of robotics, automation, electric circuits, and communications. He has served as a visiting professor at the University of Edinburgh, Scotland; The Massachusetts Institute of Technology; Stanford University; of California, Berkeley. A Fellow of the Institute of Electrical and Electronic Engineers, Dr. Dorf is widely known to the profession for his Modern Control Systems, Eighth Edition (Addison-Wesley, 1998) and The International Encyclopedia of Robotics (Wiley 1988). Dr. Dorf is also the coauthor of Circuits, Devices and Systems (with Ralph Smith), Fifth Edition (Wiley, 1992). Dr. Dorf edited the widely used Electrical Engineering Handbook, Second Edition (CRC Press and IEEE Press) published in 1997.
