A model is developed that allows simulating the most-likely failures possibly occurring in freecooling (FC) systems of telecommunication (TLC) switching rooms. Main aim to provide an effective and online implementable diagnosis method, which turn will allow fulfilling threefold function safeguarding electronic equipment, ensuring desired air quality case human presence reducing malfunction-rela...

A preference experiment was conducted to compare and evaluate the use of three cooling systems by mature gilts. Systems evaluated were snout coolers (S), drip coolers (D), and conductive cool pads (P). Preference for cooling system and pen position were continuously monitored and evaluated during daily heat stress conditions (34.2 +/- 2.8 degrees C), nightly warm conditions (26.6 +/- 2.3 degree...

The main objective of this investigation was to design and investigate a radiant panel cooling system on small scale building type (office) under the central Sudan climatic conditions so as to explore the benefits of radiant cooling systems over conventional air conditioning systems (Variable air volume systems). Transient heat conduction of building (finite difference method) was used to evalu...

Vitrification is widely used for cryopreservation of oocytes. The present study has built the theoretical models of four vitrification systems (micro-droplet, open pulled straws, quartz micro-capillary and cryotop), and performed numerical analysis to predict the cooling rates. The numerical analysis shows that the average cooling rate of the cryotop system was higher than those of other three ...
