Pseudo-random numbers are often required for simulations performed on parallel computers. The requirements for parallel random number generators are more stringent than those for sequential random number generators. As well as passing the usual sequential tests on each processor, a parallel random number generator must give different, independent sequences on each processor. We consider the req...

Renewable sources are not used to their full potential for electricity generation. Unpredictability of solar and wind power forces renewable generators to bid conservative generation amounts in a dayahead market in order to avoid fees for failure to provide generation. In this paper we propose an approach to increase the use of renewable sources, which allows renewable generators to hedge again...

this study based on investigation for integration wind power into conventional power system with its impact on fossil fuel generators and their generation management. wind power as environmental friendly energy source can reduce the operational cost of the system due to considering no cost for energizing the generator in comparing with fossil fuel generators. however due to unpredictable nature...

Most random number generators used in practice are based on linear recurrences, with linear output transformations. This gives long periods, fast implementations, and structures that are easy to analyze. But the points produced by these generators have very regular structures. Nonlinear generators can have less regular structures, but they are generally slower and much harder to analyze when th...

We present a novel counterexample generator for the interactive theorem prover Isabelle based on a compiler that synthesizes test data generators for functional programming languages (e.g. Standard ML, OCaml) from specifications in Isabelle. In contrast to naive type-based test data generators, the smart generators take the preconditions into account and only generate tests that fulfill the pre...

The collision test is one of the most important statistical tests for random number generators. It simulates the throwing of balls randomly into urns. A problem in applying this test is to determine the number of urns, m, and the number of balls, n, so that the test is among the most stringent possible on a computer available for testing. Our studies showed that for a fixed m, n shall be determ...

Results of an investigation on the application of STATCOM for damping subsynchronous resonance (SSR) in a multi-machine system is presented in this paper. For a multi-machine system which has a set of identical parallel turbine-generators or non-identical turbine-generators having torsional modes of the same frequency, generators may suffer from the same mode of torsional interaction correspond...

Tree-level scattering amplitudes in N = 4 super Yang-Mills theory have recently been shown to transform covariantly with respect to a ‘dual’ superconformal symmetry algebra, thus extending the standard superconformal symmetry algebra psu(2, 2|4) of the theory. In this paper we derive the action of the dual superconformal generators in on-shell superspace and extend the dual generators suitably ...

A known cycle length has hitherto been considered an indispensable requirement for pseudorandom number generators. This requirement has restricted random number generators to suboptimal designs with known deficiencies. The present article shows that the requirement for a known cycle length can be avoided by including a self-test facility. The distribution of cycle lengths is analyzed theoretica...
