Grahn, DA, Cao, VH, Nguyen, CM, Liu, MT, and Heller, HC. Work volume and strength training responses to resistive exercise improve with periodic heat extraction from the palm. J Strength Cond Res 26(9): 2558–2569, 2012—Body core cooling via the palm of a hand increases work volume during resistive exercise. We asked: (a) ‘‘Is there a correlation between elevated core temperatures and fatigue on...
In the recent times, the use of solar energy for the refrigeration purpose has been increasing day by day. Generally, solar used for cooling purpose has proposed many advantageous features in the refrigeration field. The cooling path is basically depends on the amount of solar radiation. The more amount of solar radiation directly increases the C.O.P. of the system. In this research paper, the ...
Given the explosive growth of data, scalability and fault tolerance have become a fundamental challenge for data center network structures. Temperature in data centers significantly affects the failure ratio of high-speed network devices. Various types of air distribution schemes influence the temperature of network equipment differently, and the cooling cost in data centers dominates the overa...
Optimal operation of the combined heat and power system (CHP) depends on the degree of its flexibility and type of operation. So, the financial and technical challenges both in choosing and economic operation of these systems will be raised. In this paper, at first, a CHP system, including auxiliary boiler, absorption and auxiliary cooling system, has change to a flexible system by adding therm...
Big Data explosion and surge in large-scale Big Data analytics cloud infrastructure have led to burgeoning energy costs and present a challenge to the existing run-time cooling energy management techniques. T ∗GreenHDFS, a thermalaware cloud file system, takes a novel, data-centric approach to reduce cooling energy costs. On the physicalside, T ∗GreenHDFS is cognizant of the uneven thermalprofi...
A methodology for assessing solar cooling technologies is proposed. The method takes into account location specific boundary conditions such as the cooling demand time series, solar resource availability, climatic conditions, component cost and component performance characteristics. This methodology evaluates the techno-economic performance of the solar collector/chiller system. We demonstrate ...
A large heat load caused by thermal radiation through a metal shield pipe was observed in a cooling test of a cryostat for a prototype of a cryogenic interferometric gravitational wave detector. The heat load was approximately 1000 times larger than the value calculated by the Stefan-Boltzmann law. We studied this phenomenon by simulation and experiment and found that it was caused by the condu...
This paper provides an overview of methods reported in the literature for generating typical load shapes required for the simulation of energy use and peak cooling loads in commercial buildings. It also includes a survey ofavailable databases ofmonitored commercial end-use electricity data, and a review of classification schemes of the commercial building stock. This study was conducted as part...
Today’s CPUs consume a significant amount of power and generate a high level of heat, requiring an active cooling system to support reliable operations. These CPUs avoid thermal breakdowns–in case of cooling system failures–through frequency-throttling mechanisms at the expense of a large performance penalty. In this paper, we first develop and validate a systemwide thermal model that can accou...
