PSGen is a new general purpose Fortran program which has been written to facilitate the Monte Carlo phase space integration of S matrix element any 2→n scattering process, with n=2,...,9, provided by user. The in 90/95. It uses very fast algorithm that automatically generates calls subroutines containing different parameterizations considered class processes. take into account mappings poles du...

This paper presents a real-time phase-domain synchronous machine model for generator protection relay testing and its real-time implementation. The model allows full protection scheme validation including split-phase differential and statorground fault protections. Space harmonics are considered through the use of modified winding function theory, which is used to represent arbitrary winding di...

We present a new tree-level matrix element generator, based on the colour dressed Berends-Giele recursive relations. We discuss two new algorithms for phase space integration, dedicated to be used with large multiplicities and colour sampling.

In this paper the Space Vector Control Scheme is implemented for a Wind Energy System using Three Level Impedance Source Inverter (ZSI). The wind energy system uses a Self Excited Induction generator (SEIG) which is the most emerging application in the field of Wind Energy Conversion System (WECS). The proposed system is modelled with a generator-side Diode Bridge Rectifier and a Stand-Alone si...

We describe a Monte Carlo event generator for the simulation of baryon-and lepton-number violating processes at supercolliders. The package, HERBVI, is designed as a hard-process generator interfacing to the general hadronic event simulation program HERWIG. In view of the very high multiplicity of gauge bosons expected in such processes, particular attention is paid to the efficient generation ...

This paper proposes a novel wind energy conversion system based on a Five-phase Permanent Magnetic Synchronous Generator (5-PMSG) and a Five to three Matrix Converter (5-3MC). The low cost and volume and also eliminating grid side converter controller are attractive aspects of the proposed topology compared to the conventional with back-to-back converters. The control of active and reactive pow...

in the first chapter we study the necessary background of structure of commutators of operators and show what the commutator of two operators on a separable hilbert space looks like. in the second chapter we study basic property of jb and jb-algebras, jc and jc-algebras. the purpose of this chapter is to describe derivations of reversible jc-algebras in term of derivations of b (h) which are we...

The aim of this paper is to clarify the sense in which number and phase in quantum optics can be described as complementary observables. Here phase observables are characterised as phase shift covariant positive operator measures, with the number operator playing the part of the shift generator. Let H be a complex separable Hilbert space, (| n〉)n≥0 an orthonormal basis, and N = ∞ n=0 n|n 〉〈n| t...

The feasibility of symbolic learning strongly relies on the efficiency of heuristic search in the hypothesis space. However, recent works in relational learning claimed that the phase transition phenomenon which may occur in the subsumption test during search acts as a plateau for the heuristic search, strongly hindering its efficiency. We further develop this point by proposing a learning prob...

دانشمندان فیزیک هسته ای همواره به دنبال مدلی برای توجیه تمام خواص و پدیده های هسته ای هستند، پیشنهاد برخی فیزیکدانان مدل کوارکی است. در این رساله به بررسی واپاشی بتا مثبت و بتا منفی از دیدگاه گذار کوارکی پرداخته شده است. به منظور بررسی واپاشی بتا با این نگرش، گذار های کوارکی به طور کامل محاسبه می شود و فرمول های بدست آمده برای تخمین جرم موثر کوارک های اولیه به کار برده می شود و بازه جرمی مورد ن...
