The present study investigates the effectiveness of thermostat control strategy in cooling energy consumption in residential buildings. To evaluate the energy consumption, two scenarios including a residential zone with and without the thermostat control system are assumed. The TRNSYS software provides an efficient numerical tool to model and evaluate a cooling system. Furthermore, since solar-...

Modern high-performance processors employ thermal management systems, which rely on accurate readings of on-die thermal sensors. Systematic tools for analysis and determination of best allocation and placement of thermal sensors is therefore a highly relevant problem. Moreover liquid cooling has emerged as a promising solution for addressing the elevated temperatures in 3D Multi-Processor Syste...

Cooling techniques have a significant impact not only on our everyday life but also on the advances in science. We have come a long way from the primitive method of evaporative cooling, which our body conveniently uses when we perspire, over the evaporation by expansion of a cooling liquid in domestic refrigerators, to high-tech methods including laser cooling, magnetic cooling, radiative cooli...

This paper studied the cutting properties of Ti-6Al-4V under cryogenic cooling to find a solution of improvement in tool load-carrying, thermal stress, tool life and finish quality. Firstly, this paper established a 3-D cutting model of Ti-6Al-4V under cryogenic cooling with liquid nitrogen, and then set the parameters of material, friction model and cutting conditions. Based on this model, the...

A generalized analytical solution to the set of coupled energy balance equations governing heat transfer in a system comprised of uniform radius spherical particles, with nonuniform initial temperature, heated in a well mixed liquid with time varying temperature, is initially derived. Based on this solution, analytical equations describing the temperature evolution for both fluid and particles,...

BACKGROUND The aim of this study was to compare the viability of human pronuclear oocytes subjected to vitrification using cooling by direct submerging of open-pulled straws in liquid nitrogen versus vitrification by cooling of open-pulled straws located inside a closed 0.5 ml straw (aseptic system). METHODS Two- and three-pronuclei stage oocytes (n=114) were cryopreserved in super-open-pulle...

By increase in the power of computer systems and enhanced power of the components and their temperature, including the central processing unit (CPU), cooling just by the air is not effective and there is need for more powerful systems to cool down and increase the power of the cooling system. In this article simulation of the heat exchanger material of the fluid cooling system has been studied ...

Muon ionization cooling is the only solution to prepare high brilliance muon beams necessary for a Neutrino Factory or Muon Collider. The International Muon Ionization Cooling Experiment (MICE) is under development at the Rutherford Appleton Laboratory (RAL). A dedicated beam line generates a range of input emittances and momenta, with time-of-flight (TOF) and Cherenkov detectors to ensure a pu...

Oocyte cryopreservation is of key importance in the preservation and propagation of germplasm. Interest in oocyte cryopreservation has increased in recent years due to the application of assisted reproductive technologies in farm animals such as in vitro fertilization, nuclear transfer and the need for the establishment of ova/gene banks worldwide. However, the cryopreservation of the female ga...

When a liquid melt is cooled, a glass or phase transition can be obtained depending on the cooling rate. Yet, this behavior has not been clearly captured in energy-landscape models. Here, a model is provided in which two key ingredients are considered in the landscape, metastable states and their multiplicity. Metastable states are considered as in two level system models. However, their multip...
