We generalize a model for friction at a sliding interface involving the motion of misfit dislocations to include the effect of thermally activated transitions across barriers. We obtain a comparatively simple form with the absolute zero-temperature Peierls barrier replaced by an effective Peierls barrier which varies exponentially with temperature, in agreement with recent experimental observat...

There is a lack of thermal models for storage clusters; most existing thermal models do not take into account the utilization of hard drives (HDDs) and solid state disks (SSDs). To address this problem, we build a thermal model for hybrid storage clusters that are comprised of HDDs and SSDs. We start this study by generating the thermal profiles of hard drives and solid state disks. The profili...

With electric power systems becoming more compact and increasingly powerful, the relevance of thermal stress especially during overload operation is expected to increase ceaselessly. Whenever critical temperatures cannot be measured economically on a sensor base, model lends itself estimate those unknown quantities. Thermal models for are usually required both, real-time capable high estimation...

We describe a three-dimensional dynamical system, which is obtained as a pseudo-spectral approximation to a free boundary problem modeling solid combustion and rapid solidification, and is capable of generating its major dynamical patterns. These patterns include a Hopf bifurcation followed by a sequence of secondary period doubling and a transition to chaos, reverse sequences, and sequences fo...

Pain sensation has been studied extensively, over a range of scales, from the molecular level to the entire human neural system. Thermal stimulation of pain has been widely used in the study of pain sensation. Skin thermal pain is induced through both direct (an increase/decrease in temperature) and indirect (thermomechanical and thermochemical) ways, and is governed by complicated thermomechan...

We consider the nonequilibrium dynamics of a a real scalar field in a degenerate double-well potential. The system is prepared in the lowest free energy state in one of the wells and the dynamics is driven by the coupling of the field to a thermal bath. Using a simple analytical model, based on the subcritical bubbles method, we compute the fraction of the total volume which fluctuates to the o...

The two primary functions of a vehicle climate control system are safety through de-icing and de-fogging windows, and occupant thermal comfort. However, vehicle air-conditioning systems can significantly impact fuel economy and tailpipe emissions of conventional and hybrid electric vehicles (HEVs) and reduce electric vehicle (EV) range. In order to meet the new U. S. Supplemental Federal Test P...

The most recent, and arguably one of the most difficult obstacles to the exponential growth in transistor density predicted by Moore’s Law is that of removing the large amount of heat generated within the tiny area of a microprocessor. The exponential increase in power density and its direct relation to on-chip temperature have, in recent processors, led to very high cooling costs. Since temper...
