Hamiltonian normalization in the restricted many-body problem by computer algebra methods
Programming and Computer Software - Tập 38 - Trang 156-166 - 2012
A symbolic algorithm for construction of a real canonical transformation that reduces the Hamiltonian determining motion of an autonomous two-degree-of-freedom system in a neighborhood of an equilibrium state to the normal form is discussed. The application of the algorithm to the restricted planar circular three-body problem is demonstrated. The expressions obtained for the coefficients of the Ha...... hiện toàn bộ

A new double sorting-based node splitting algorithm for R-tree
Programming and Computer Software - Tập 38 - Trang 109-118 - 2012
A storing of spatial data and processing of spatial queries are important tasks for modern data-bases. The execution efficiency of spatial query depends on underlying index structure. R-tree is a well-known spatial index structure. Currently there exist various versions of R-tree, and one of the most common variations between them is node splitting algorithm. The problem of node splitting in one-d...... hiện toàn bộ

The use of artificial neural networks for classification of signal sources in cognitive radio systems
Programming and Computer Software - Tập 42 - Trang 121-128 - 2016
In the paper, methods of classification of signal sources in cognitive radio systems that are based on artificial neural networks are discussed. A novel method for improving noise immunity of RBF networks is suggested. It is based on introducing an additional self-organizing layer of neurons, which ensures automatic selection of variances of basis functions and a significant reduction of the netwo...... hiện toàn bộ

A definite summation of hypergeometric terms of special kind
Programming and Computer Software - Tập 37 - Trang 187-191 - 2011
A definite summation of hypergeometric terms of two variables is considered. Currently, for summation of such terms in computer algebra systems, a combination of the Zeilberger algorithm and the discrete Newton-Leibniz formula is used. As is known, the result of such summation is not always correct. In the paper, it is proposed to use simple preliminary examination of the term before applying the ...... hiện toàn bộ
