Numerous techniques in designing zones happen at high temperature and functions under high temperature are in a way that involves non-linear radiation. In weakly conducting fluids, however, the currents induced by an external magnetic field alone are too small, and an external electric field must be applied to achieve an efficient flow control. Gailitis and Lielausis, devised Riga plate to gene...

introduction: time series models are generally categorized as a data-driven method or mathematically-based method. these models are known as one of the most important tools in modeling and forecasting of hydrological processes, which are used to design and scientific management of water resources projects. on the other hand, a better understanding of the river flow process is vital for appropri...

in this paper, considering the importance of incoming flow turbulence intensity into combustion chamber, tripping wire effect on the flow wake has been experimentally investigated within a linear compressor cascade. to do this, two wires were implemented along each blade and their effects on average velocity, turbulence intensity and vortices frequencies at reynolds number 45500 were accurately...

Let us commence by recalling the multicommodity flow problem and its 4 dual, the problem of packing metrics by cuts. A pair S s A, B of nonempty disjoint subsets of a finite set V is called a cut if B s V y A. Ž . Consider a network N s G, H, c, q consisting of a supply graph G s Ž . q 4 V, E endowed with a capacity function c: E a R j 0 , a demand graph Ž . q 4 H s X, F with X : V, and a deman...

This article presents a model for investing in renewable energies in the framework of the Spanish electricity market in a way that risk is minimised for the investor while returns are maximised. The model outlined here is based on an economic model for calculating cash flows intended to obtain the internal rate of return (IRR) of the different energies being studied: wind, photovoltaic, mini hy...

The aim of this study is to develop a methodology for selection of routing of different categories of intercity passenger trains taking into account of the uncertainty of the processes and using the fuzzy linear programming method. The fuzzy theory allows for the presentation of real data with uncertainty due to imprecise measurement. This research studies the fuzzy problems with fuzzy constrai...
