The decomposition of seven herbicides (atrazine, linuron, lenacil, chloridazon, dinoseb acetate, prometryn, and diuron) was carried out by detonative combustion. investigated blasting material produced on the basis porous ammonium nitrate, which served as an oxidizer, while pesticides played role fuel. Detonative mixtures in blast-holes soil. efficiency process assessed using techniques gas chr...

This paper develops a slack-based decomposition of profit efficiency based on a directional distance function.

Seismic waves are non-stationary due to its propagation through the earth. Time-frequency transforms are suitable tools for analyzing non-stationary seismic signals. Spectral decomposition can reveal the non-stationary characteristics which cannot be easily observed in the time or frequency representation alone. Various types of spectral decomposition methods have been introduced by some resear...

In this paper we propose a new combined approach to feature space decomposition to improve the efficiency of the nonlinear dimensionality reduction method. The approach performs the decomposition of the original multidimensional space, taking into account the configuration of objects in the target low-dimensional space. The proposed approach is compared to the approach using hierarchical cluste...

This paper mainly designed a new method of using the Parallel LU Decomposition Algorithm for solving large-scale dense linear equations on the basis of the strategy of divide and rule,and analyzed the speedup and efficiency of the Parallel LU Decomposition Algorithm. In theory, it could improve the efficiency of problem-solving. In addition, the extension of Parallel LU Decomposition Algorithm,...

Many time-varying phenomena of various fields in science and engineering can be modeled as a stochastic differential equations, so investigation of conditions for existence of solution and obtain the analytical and numerical solutions of them are important. In this paper, the Adomian decomposition method for solution of the stochastic differential equations are improved.  Uniqueness and converg...

An algorithm for decomposition of highly multicomponent signals, with variable components energy, has been proposed. The algorithm combines the singular value decomposition with the suitable time-frequency analysis approach. The auto-correlation matrix is obtained by applying the inverse form of the cross-terms free time-frequency distribution. The decomposition of the time-frequency based auto...

Configuration was one of the first tasks successfully approached via AI techniques. However, solving configuration problems can be computationally expensive. In this work, we show that the decomposition of a configuration problem into a set of simpler and independent subproblems can decrease the computational cost of solving it. In particular, we describe a novel decomposition technique exploit...

In this paper an efficient method is developed for the analysis of non-regular graphs which contain regular submodels. A model is called regular if it can be expressed as the product of two or three subgraphs. Efficient decomposition methods are available in the literature for the analysis of some classes of regular models. In the present method, for a non-regular model, first the nodes of the ...
