Ten men (non-firefighters) completed a 110 min walking/recovery protocol (three 20-min exercise bouts, with recovery periods of 10, 20, and 20 min following successive bouts) in a thermoneutral laboratory while wearing firefighting personal protective equipment over one of four base layers: cotton, modacrylic, wool, and phase change material. There were no significant differences in changes in ...

background and objective: in magnetic fluid hyperthermia therapy, controlling temperature elevation and optimizing heat generation is an immense challenge in practice. the resultant heating configuration by magnetic fluid in the tumor is closely related to the dispersion of particles, frequency and intensity of magnetic field, and biological tissue properties. methods: in this study, to solve h...

Multi-core architectures have become more popular due to better performance, reduced heat dissipation, power consumption and more efficient simultaneous processing of multi tasks. If one wishes to run a single application faster, then that application must be divided into sub programs, or threads, that cooperate to deliver the desired functionality. The Open MP programming paradigm implements l...

Due to increase in MOS scaling, frequency and bandwidth of high performance CMOS VLSI circuits, on-chip consumed power is enhanced. It creates an important role in both switching and dc power dissipation. This dissipated power is usually rehabilitated into degenerated heat, affecting the performance and consistency of a chip. In this paper we contribute: an algorithm for thermal bound placement...

Introduction Enceladus is emitting measurable heat (37 GW) from a region centered on its South Pole [1]. Radioactive and accretional heating are expected to be minimal for such a small, low-density body, implying that the observed heat flow is due to past or present tidal dissipation [2]. The tidal heat production for which Enceladus’ eccentricity is in steady state, however, cannot exceed 1.1 ...

George Mekhtarian PMM, Synopsys Why Multicore Analysis? In the last few years, the trend in CPU performance improvement has shifted from raw computational speed to parallelism as various memory and power (heat dissipation) limits have been reached at the higher clock frequencies. After surpassing clock speeds of 3 GHz, further CPU performance improvement is now achieved by increasing the number...

The Earth’s mantle convects to lose heat (Holmes, 1931); doing so drives plate tectonics (Turcotte and Oxburgh, 1967). Significant gravitational energy is created by the cooling of oceanic lithosphere atop hotter, less densemantle. When slabs subduct, this gravitational energy is mostly (∼86% for whole mantle flow in a PREM-like mantle) transformed into heat by viscous dissipation. Using this p...

We give a decomposition expression for dissipative heat using the instantaneous diffusion coefficient in a nonequilibrium steady state. The dissipative heat can be expressed using three diffusion coefficients: instantaneous, equilibrium, and drift. An experimental application of the decomposition expression permits us to evaluate the heat dissipation rate from singletrajectory data only. We als...

Directed Energy Weapon (DEW) systems in a pulse operation mode dissipate excessively large, transient waste heat because of their inherent inefficiencies. The heat storage system can store such a pulsed heat load not relying on oversized systems and dissipate the stored heat over time after the pulse operation. A compressor-driven metal hydride heat storage system was developed for efficient, c...
