where Uj and Vj denote the values of the approximate solution at position jA and at times t and / + A respectively. We have chosen here for simplicity the same value A for both time and space increments. The coefficients Cj depend on the index k ; we assume that this dependence is Lipschitz continuous, i.e., that c(k + l)— c(k) = 0(A). Since the differential equation (1) is homogeneous, u = con...
concerns related to climate change and security of energy supply is pushing various countries to make strategic energy planning decisions. in this regard, energy system modelling is an appropriate method to find out the utilization of current declining non-renewable energy resources and other possible scenarios. consequently, it is available to consider various aspects of energy system decision...
one hundred twenty male broiler chickens of 20 d of age were used to study the effect of enzyme supplementation on the apparent metabolisable energy corrected for nitrogen in corn, wheat and triticale using total excreta collection or marker methods. the average apparent metabolisable energy corrected for nitrogen in corn, wheat and triticale on dry matter basis, were 3480 ±90, 3263 ±61 and 326...
Dumps of a mining-metallurgical complex of post-Soviet Republics have accumulated a huge amount of technogenic waste products. Out of them, Kazakhstan alone has preserved about 20 billion tons. In the field of technogenic waste treatment, there is still no technical solution that leads it to be a profitable process. Recent global trends prompted scientists to focus on developing energy-saving a...
Over the past few years, several schemes for *. making significant increases in the energy of the SLAC beam have been proposed. Two of the proposals, namely the use of superconducting accelerating sections1 and recirculation 1 of the beam for a second pass through the existing acceler. &or,’ have been abandoned for technical and economic reasons after extensive investigation. An on-going method...
This article discusses the addition of an energy parameter to the shortest path execution process; namely, the energy expenditure by a character during execution of the path. Given a simple environment in which a character has the ability to perform actions related to locomotion, such as walking and stair stepping, current techniques execute the shortest path based on the length of the extracte...
Aim of this paper is to give an extensive treatment of bipartite mean field spin systems, ordered and disordered: at first, bipartite ferromagnets are investigated, achieving an explicit expression for the free energy trough a new minimax variational principle. Furthermore via the Hamilton-Jacobi technique the same free energy structure is obtained together with the existence of its thermodynam...
this paper concentrates on a new procedure which experimentally recognises gears and bearings faults of a typical gearbox system using a least square support vector machine (lssvm). two wavelet selection criteria maximum energy to shannon entropy ratio and maximum relative wavelet energy are used and compared to select an appropriate wavelet for feature extraction. the fault diagnosis method co...

This work is concerned with the finite element approximation of a class of stress-free martensitic microstructures modeled by multi-well energy minimization. Finite element energy-minimizing sequences are first constructed to obtain bounds on the minimum energy over all admissible finite element deformations. A series of error estimates are then derived for finite element energy minimizers.
