In this paper we consider robust output regulation of distributed parameter systems and the internal model principle. The main purpose is to generalize the internal model principle by Francis and Wonham for infinite-dimensional systems and clarify the relationships between different generalizations of the internal model. We also construct a signal generator capable of generating infinite-dimens...

We propose a secret sharing scheme based on rings or modules that admit a decomposition given by orthogonal idempotents of the ring. The secret is decomposed into partial secrets that belong to the projections induced by every idempotent. These projections are indeed ideal codes and thus the subsecrets are distributed among a group of users using the generator matrix of these ideal codes.

The organization and functional properties of interneurons in the flight system of the locust, Locusta migratoria, were investigated by using intracellular recording and staining techniques. Interneurons were found to be distributed within the three thoracic and the first three abdominal ganglia, and they could be subdivided into three organizational categories: (1) members of one of two serial...

Two closely-related pseudo-random sequence generators are presented: The lIP generator, with input P a prime, outputs the quotient digits obtained on dividing by P. The x mod N generator with inputs N, Xo (where N P. Q is a product of distinct primes, each congruent to 3 mod 4, and x0 is a quadratic residue mod N), outputs bob1 b2" where bi parity (xi) and xi+ x mod N. From short seeds each gen...

in this article our objective is to obtain steady state characteristics of shunt, series, and separately excited dc motors coupled with a centrifugal water pump supplied through a step-up, step-down, and cuk converter from photovoltaic generator. we assume that there are no storage batteries and, of course, the system must operate on maximum utilization i.e. maximum water must be pumped. it is ...

The main bearing is the core component of gas-fired generator, and its reliability directly affects stability whole system. Therefore, it great significance to study fault diagnosis generator. In based on vibration signal, how extract signature features effectively key achieving accurate diagnosis. Based extracting faults, classify efficiently another this, we propose a method Mel frequency cep...
