Research Interest

My very first research efforts started in 1963 while I was working for the I.B.M. Scientific Center at Los Angeles. These efforts led to my first paper, in the field of Automata Theory, which was published in the SIAM Journal of Control in 1968 (see publ[1]). At the time, I was completing my Ph.D. thesis on von Neumann algebras. My first publications, naturally enough, were in that general area (see pub[2] and pub[3] for example). Later I was able to obtain related results for norm closed algebras, i.e. C* algebras (for example see pub[5] and pub[12]). Later still I developed an interest in integration theory and other areas of functional analysis.

From 1975 I became more interested in Probability (for example see pub[22] and pub[38]), Control Theory (for example see pub[49] and pub[37]), Non Linear Analysis (for example see pub[34] and pub[41]) and Numerical Analysis (for example see pub[45] and pub[51]).

In 1978 I became interested in Computer Science. This was brought about in a rather natural way as the Department of Mathematics at Indiana State had decided to go ahead with a B.S. program in Computer Science. In 1983 I held the rank of Professor in the Department of Computer and Information Science of Indiana University, Purdue University at Indianapolis.

My initial research interests include the construction of stochastic models for information flows, see pub[53] through pub[57]. In pub[55] we study a mechanism followed by a decision maker ethically bound to pursue the best available course of action. The model allows for feedback information to be input for each cycle of decision making. Equations describing the updated expected utilities in terms of the learning factor are obtained. The estimators obtained from a martingale or a submartingale allowing the analysis of when and how the decision maker can terminate the feedback decision-making loop. In pub[56] the study is generalized so that termination is analyzed although the estimators do not form a martingale or a submartingale. More recent articles pub[57] pub[64] ,for example,

My more recent research pub[70] is in the areas of the mathematical theory of evidence, uncertainty in expert systems, knowledge acquisition, fuzzy logic, neural nets, neuron-fuzzy systems and how to apply these theories to the problems of object recognition and expert systems construction, as well as to business problems. This work was funded by NASA for the Summers of 88, 89, 90, 91 and for the year 1992 as well as by NSF and the Army Research Office from 1995 to 1999. Fuzzy logic, the Dempster Shafer theory and Rough sets are important techniques used to investigate many problems in these areas.
