A spectral window in the thermal infrared permits observations of surface temperature by satellite radiometry. The Heat Capacity Mapping Mission (HCMM) acquired 10-12/tm data at times of day favorable for estimation of surface thermal properties and the surface energy budget. Two variables, surface wetness, which controls evaporation and hence mean surface temperature, and thermal inertia, whic...
Soil moisture is generally regarded as the limiting factors in rangeland production. Although many studies have been conducted to estimate soil moisture in semiarid areas, there is little information on mountainous rangelands in west of Iran. The present study aims to investigate the soil moisture estimation in rangelands as compared to the other land uses over a mountainous area in central Zag...
One of the most important control methods in induction motor is direct vector control. This method is based on rotor flux estimation using stator voltage. The machine voltage is low in The voltage model for low speed and voltage drop over the stator resistance is not negligible in front of stator voltage. Thus the stator flux estimation using voltage method is not precise. Some methods are base...
