consumes. The main function of HVAC is to overcome thermal load in the space it serves in order to provide desirable comfort to space occupants. This thermal load comes in two ways of heat transfer such as convection and radiation. Space lighting is a common source of heat transfer by radiation and therefore its intensity must be minimized to an acceptable level to reduce its effect on HVAC performance. This thesis includes the design of fuzzy logic controller for lighting systems. Since HVAC

Premium Homeostasis Metabolism Physiology
We gain heat by the metabolism of food and by absorbing solar energy from objects‚ from the ground and connections with the ground. However we lose heat by evaporation (sweat)‚ conduction (lost to the ground or by touching cooler objects)‚ convection (heat lost upwards to the cooler air) and radiation (moved out from the body in all directions to the cooler air). Humans are warm blooded and derive most of their heat from metabolism‚ and loose heat through our respiratory surfaces‚ the gut

age to be 98 million years and recounted that age to determine that it was actually between 20 and 40 million years old. He used a very thorough method and ended up being wrong on both counts because he was unaware of the existence and effects of radiation. There was another method of aging the Earth utilizing the relative positions of rock layers. Ensuring that unconformities were accounted for‚ that fossils were used as benchmarks‚ and understanding what rocks are older than others‚ this relative

Theory CONDUCTORS‚ INSULATORS AND CONDUCTIVITY Conduction of electricity in electric circuits takes place due to the presence of excess electrons in materials called conductors. Electrons move in the direction in which the potential has been applied. The ability of a conductor to conduct electricity is directly proportional to the material’s area of cross section and inversely proportional to its length. Where‚ G is conductance σ is conductivity A is area of cross section
