In this paper we introduce error-control techniques for improving the error-rate performance that is delivered to an application in situations where the inherent error rate of a digital transmission system is unacceptable. The acceptability of a given level of bit error rate depends on the particular application. For examples, certain types of digital speech transmission are tolerant to fairly ...

The old intuitive question ”what does the machine think” at different stages of its computation is examined. Our paper is based on the formal definitions and results which are collected in the branching program theory around the intuitive question ”what does the program know about the contents of the input bits” [1],[2],[3],[4],[5]. We further develop these results above and we present a formal...

If you expect a nobel prize winner being a crank who can think of nothing but his subject, then read Roald Hoffmann's The Same and Not the Same and test your hypothesis. This book is about chemistry, to be sure – but in the broadest scope including sociology, psychology , ethics and philosophy of chemistry. 51 nice little chapters grouped in ten parts reflect on chemistry from different aspects...

In this thesis we describe a new class of error control codes that is designed to be used over " Multi-Bit Differential Signaling (MBDS), " a new off-chip signaling technology. This new class of codes, called " Lightweight Hierarchical Error Control Codes (LHECC), " takes advantage of inherent structural properties of MBDS's channel encoding mechanism, called " N choose M (nCm) " encoding. Thes...

An approach to constructing a Pareto front approximation to computationally expensive multiobjective optimization problems is developed. The approximation is constructed as a sub-complex of a Delaunay triangulation of a finite set of Pareto optimal outcomes to the problem. The approach is based on the concept of inherent nondominance. Rules for checking the inherent nondominance of complexes ar...
