whereas in electrical discharge machining (edm) the heat flux entering the workpiece is extremely high, the fourier heat conduction model may fails. this article reports on determination of temperature distribution in the workpiece due to edm using non-fourier heat conduction model. equations are solved by deriving the numerical solution. the temperature layers and profiles of sample calculatio...

Thermal conduction modes in a nanocolloid (nanofluid) are quantitatively assessed by combining linear response theory with molecular dynamics simulations. The microscopic heat flux is decomposed into three additive fluctuation modes, namely, kinetic, potential, and collision. For low volume fractions (<1%) of nanosized platinum clusters which interact strongly with xenon host liquid, a signific...

Our aim in this paper is to study a generalization of the Caginalp phasefield system based on the theory of type III thermomechanics with two temperatures for the heat conduction. In particular, we obtain well-posedness results and study the dissipativity of the associated solution operators. We consider here both regular and singular nonlinear terms. Furthermore, we endow the equations with tw...

Green house gases emission associated with natural hazard of underground coal seam fire has been recognized as a worldwide problem leading to global warming threat. Therefore, in this paper a model to study underground coal fire is presented and the results will be devoted to strategic development of coal fire extinction technology within the framework of Sino-German Coal Fire Research Initiati...

Online auctions are among the most influential e-business applications. Their impact on trading for businesses, as well as consumers, is both remarkable and inevitable. There have been considerable efforts in setting up market places, but, with respects to market volume, online trading is still in its early stages. This chapter discusses the benefits of the concept of Internet marketplaces, wit...

Mycoplasma is a virulent organism that is known to primarily infect the respiratory tract; however, affection of the skin, nervous system, kidneys, heart and bloodstream has been observed in various forms, which include Stevens Johnson syndrome, erythema multiforme, toxic epidermal necrolysis, encephalitis, renal failure, conduction system abnormalities and hemolytic anemia. Small vessel vascul...

in this paper, a numerical solution of an inverse non-dimensional heat conduction problem by spline method will be considered. the given heat conduction equation, the boundary condition, and the initial condition are presented in a dimensionless form. a set of temperature measurements at a single sensor location inside the heat conduction body is required. the result show that the proposed meth...

Built-in/internal fields in Wurtzite quantum dots originate mainly from: (1) the fundamental crystal atomicity and the interfaces between two dissimilar materials, (2) the strain relaxation, (3) the piezoelectricity, and (4) the spontaneous polarization/pyroelectricity. In this paper, using the atomistic NEMO 3-D simulator, we study the influence of these four competing internal fields on the e...

We introduce a new family of networks, the Apollonian networks, that are simultaneously scale-free, small-world, Euclidean, space filling, and with matching graphs. These networks describe force chains in polydisperse granular packings and could also be applied to the geometry of fully fragmented porous media, hierarchical road systems, and area-covering electrical supply networks. Some of the ...

The time and temperature dependences of conductivity of four polymers namely polyindole, polyindole-5-carboxylic acid, polycarbazole, and poly(N-vinylcarbazole) are analysed to understand the aging process and conduction mechanism. The polymers are prepared electrochemically. The conductivity data obtained over a temperature range are fitted to Arrhenius and Mott equations. The thermal degradat...
