Measurement of solar ultraviolet radiation in Yazd, Iran
Background: Ultraviolet (UV) radiation is divided into three regions: UVA, UVB, and UVC. Both the quality and quantity of solar UV radiation vary with various factors including the elevation of the sun above the horizon, as well as absorption and scattering of UV photons by molecules in the atmosphere, notably ozone and clouds. It is clear that whereas a moderate amount of UV exposure ...
متن کاملMeasurement of UVA exposure to solar radiation.
Exposure to solar UVA (320-400 nm) radiation can damage DNA and lead to skin disorders. Conventional dosimetry using a single piece of polysulfone or diglycol carbonate (CR-39) cannot provide accurate measurement of the biologically effective irradiance for erythema for the UVA waveband. A package employing four dosimeters (polysulfone, nalidixic acid, 8-methoxypsoralen and phenothiazine) has b...

متن کاملSolar Energy Potentials and Radiation Map of Lorestan Province
Solar energy is the most unique renewable energy source in the world and is the main source of all energy on Earth. Solar energy can be converted into other forms of energy directly and indirectly. In general, the energy given off by the sun about 3. 8 two 1023 kW per second. In the present study, the potential of solar energy in the province of surveillance data 9 synoptic stations located in ...
متن کاملNeural daylight control system
The paper describes the design, the implementation of a neural controller used in an automatic daylight control system. The automatic lighting control system (ALCS) attempt to maintain constant the illuminance at the desired level on working plane even if the daylight contribution is variable. Therefore, the daylight will represent the perturbation signal for the ALCS. The mathematical model of...
