Solution of some problems on multicore processors. New methods and modeling in the MATLAB. By Solomon I. Khmelnik
Paperback: $500.00
Prints in 3-5 business days
We are presenting a new method and algorithm for solving several common problems of linear algebra and optimization, where only vectors multiplication is used (matrices inversion and division is... More > absent). The solution of these problems is reduced to consequently performed multiplication of a matrix by a vector. It leads to significant simplification of the corresponding programs for multi-core processors, and the solution time is very much reduced. Open codes of the programs in MATLAB system are presented. In these programs the above mentioned method is realized for a single-core processor. Propositions of additional projects may be sent to the address solik@netvision.net.il.< Less

Variational Principle of Extremum in Electromechanical Systems By Solomon I. Khmelnik
Paperback: $30.00
Prints in 3-5 business days
The variational principle of extremum is stated and proved for electromechanical systems of arbitrary configuration wherein the electromagnetic, mechanical, thermal hydraulic and other processes are... More > going on. It is shown that for such systems there exists a pair of functionals with a global saddle point. For systems without electric circuits the suggested principle is equivalent to the minimum action principle. The principle is generalized for the systems described by partial differential equations, and in particular by Maxwell equations. A speedy universal algorithm for computation of such systems with arbitrary excitations is described. In this algorithm a method of searching for global saddle point simultaneously on two functionals is realized. The book contains numerous examples, including those presented as M-functions of the MATLAB system.< Less

More > processes are going on. The principle is generalized for systems described by partial differential equations, including also Maxwell equations. The presented principle permits to expand the Lagrange formalism and extend the new formalism on dissipative systems. It is shown that for such systems there exists a pair of functionals with a global saddle point. A high-speed universal algorithm for such systems calculation with any perturbations is described. This algorithm realizes a simultaneous global saddle point search on two functionals. The algorithms for solving specific mathematical and technical problems are cited. The book contains numerous examples, including those presented as M-functions of the MATLAB system and as functions of the DERIVE system.< Less
