today air conditioning systems have been considered by all people as one of welfarerequirements in buildings and closed environments. since a considerable part of energy lossoccurs in ordinary modern systems, new strategies and solutions are developed in the field inorder to save amount of energy consumption and observe environmental considerations. fuzzycontrol is one of these methods which pr...

The article focuses on the description of an innovative solution and application active thermal protection buildings using insulation panels with regulation heat transfer in form a contact system. are part prefabricated lightweight outer shell, which together low-temperature heating high-temperature cooling system creates indoor environment. energy source is usually renewable sources or technol...

The thermodynamics of laser cooling of solids is analyzed. Using the general theory of radiation entropy, the important roles of the optical frequency and the photon distribution function in determining the radiation entropy are identified. The usefulness of a narrow-band approximation is established for a wide range of radiant sources. This approximation is then applied to compare the entropie...

The fall in body temperature that occurs in babies soon after birth is influenced by the baby's weight and its environmental conditions. The rate of oxygen consumption 1 1/2 hours after birth was unrelated to body temperature and only slightly raised, indicating a limited thermogenic capacity. A radiant heater effectively prevented cooling in babies kept with their mothers in the delivery room....
