We review the results of our experimental investigation of heat conduction in suspended graphene and offer a theoretical interpretation of its extremely high thermal conductivity. The direct measurements of thermal conductivity of graphene were performed using a non-contact optical technique and special calibration procedure with bulk graphite. The measured values were in the range of ∼3000–530...

Switched reluctance motors (SRM) are attracting much attention because of their special advantages. Generated heat, due to losses, can reduce the life time of SRMs. Therefore, taking into account thermal modeling helps to improve their performance and increase their life time. In this paper, a lumped thermal model of SRM based on the analogue circuit of conductive and convective thermal resista...

We make the observation that a brane universe accelerates through its bulk spacetime, and so may be interpreted as an Unruh observer. The bulk vacuum is perceived to be a thermal bath that heats matter fields on the brane. It is shown that, aside from being relevant in the early universe, an asymptotic temperature exists for the brane universe corresponding to late time thermal equilibrium with...

Phase change memory (PCM) is one of the frontrunners among the emerging non-volatile memory technologies. Even though a Joule-heating-induced phase change mechanism has been demonstrated down to a few nanometer dimensions, a key factor that could possibly limit the scaling trends in a PCM memory array is the thermal cross-talk between adjacent cells. In this article we present a compact electro...

This paper describes the instrumentation for broadband frequency domain thermoreflectance (BB-FDTR), a novel, continuous wave laser technique for measuring the thermal conductivity accumulation function. The thermal conductivity accumulation function describes cumulative contributions to the bulk thermal conductivity of a material from energy carriers with different mean free paths. It can be u...

As integrated circuits (ICs) have scaled into nanometer dimensions, operating at gigahertz frequencies, interconnects have become critical in determining system performance, reliability, and manufacturability. This thesis presents new algorithms dealing with several important aspects of VLSI interconnects optimization and prediction, namely, noise reduction in global routing, temperature-aware ...

Background & Objective: It is reported that acute forced swimming stress induces analgesia immediately, and chronic stress induces hyperalgesia. Whereas in response to nociceptive stimulation, small-diameter C-fibers of the excitatory system in the dorsal horn of the spinal cord are activated, therefore, in the present study, the effects of C-fiber lesion in stress and dexamethasone-induced ana...
