this paper modeled heating air of a room through examining free convection in a 3d chamber. the chamber had cold and hot sources with tc and th temperatures, respectively. its other walls were adiabatic. this study aimed at predicting effect of temperature difference, displacement of hot and cold sources and their aspect ratio on flow field, temperature and heat transfer rate. to conduct the st...

People experiences heat propagation since ancient times. The mathematical foundations of this phenomenon were established nearly two centuries ago with the early works of Fourier [Fourier, 1952]. During this time the equations describing the conduction of heat in solids have proved to be powerful tools for analyzing not only the transfer of heat, but also an enormous array of diffusion-like pro...

Abstract. The original Budyko–Sellers type of 1D energy balance models (EBMs) consider the Earth system averaged over long times and apply continuum mechanics heat equation. When these more phenomenological box are extended to include time-varying anomalies, they have a key weakness: neither model explicitly nor realistically treats conductive–radiative surface boundary condition that is necess...

Routing is highly challenging task network, which the random model used to ascertain through put and energy depletion. classified into multiple regions. Scheduled time slot assigned for data transmission between source sink. table p...

An indoor power line is one of the most attractive media for in-home networks. However, there are many technical problems for achieving in-home power line communication (PLC) with high rate and high reliability. One of such problem is the degradation in the performance of the in-home PLC caused by periodically time-varying channel responses, particularly when connecting the switching power supp...

In this article, the influence of thermal conductivity on dynamics a rotating nanobeam is established in context nonlocal thermoelasticity theory. To end, governing equations are derived using generalized heat conduction including phase lags basis Euler–Bernoulli beam The proposed model linearly changes with temperature and considered excited variable harmonic source exposed to time-dependent l...

We consider a single-link multi-source network with FAST TCP sources. We adopt a continuous-time dynamic model for FAST TCP sources, and propose a static model to adequately describe the queuing delay dynamics at the link. The proposed model turns out to have a structure that reveals the time-varying network feedback delay, which allows us to analyze FAST TCP with due consideration of the time-...
