With the ever-growing cooling costs of largescale data centers, thermal management must be adequately addressed. Thermal models can play a critical role in thermal management that helps in reducing cooling costs in data centers. However, existing thermal models for data centers can overload I/O activities. To address this issue, we developed an I/O-aware thermal model called iTad for data cente...

the energy requirement of vacuum membrane distillation (vmd) with or without recirculation was modelled using both experimental results and theoretical data. the trends are generally consistent between the theoretical and experimental data. thermal energy contributes the most to the total energy required for the vmd process. to lower the thermal energy cost, waste heat resource and heat recover...

  Objective: Studies have demonstrates that physical properties of denture base affect patient satisfaction and acceptance. Thermal conductivity is among the most important properties of denture base influencing the sense of taste and gingival health. The conventionally used acrylic resin has a low coefficient of thermal conductivity. This study aimed to improve the thermal conductivity of acry...

Simulated Thermal Response Test data are analyzed in order to evaluate the effect of the tridimensionality model’s feature in determining the proper value of the soil thermal conductivity and borehole thermal resistance, necessary for the geothermal energy storage systems’ design in real conditions. The 3D system’s simulation during the Thermal Response Test is realized by adopting the finite e...

A three-dimensional finite difference model was employed for the borehole ground heat exchanger to perform a thermal response test analysis using the parameter estimation technique. This allowed the groundwater velocity to be determined simultaneously together with the ground thermal conductivity and the borehole thermal resistance. It was found that the estimated groundwater velocity scattered...

The influences of filler size and content on the properties (thermal conductivity, impact strength and tensile strength) of Al2O3/high density polyethylene (HDPE) composites are studied. Thermal conductivity and tensile strength of the composites increase with the decrease of particle size. The dependence of impact strength on the particle size is more complicated. The SEM micrographs of the fr...

Although lateral thermal conduction in Ge2Sb2Te5 (GST) films can influence the performance of phase change memory (PCM), there are no data available for the in-plane thermal conductivity. This work measures both the in-plane and the out-of-plane thermal conductivities for the amorphous, face-centered-cubic, and hexagonal-close-packed phases of GST using two independent techniques. For crystalli...
