Emissivity mapping of the Earth’s surface is the prerequisite to thermal remote sensing. A precise determinationof a surface's temperature is dependent upon the availability of precise emissivity data for that surface. The presentstudy area is a part of sugarcane plantation fields in the west part of Khuzestan province. In this work, TemperatureEmissivity Separation algorithm (TES) was applied ...
A fundamental function of any aviation weather system is to provide accurate and timely weather information tailored to the specific air traffic situations for which a system is designed. Weather location and intensity are of prime importance to such systems. Knowledge of the weather provides “nowcasting” functionality in the terminal and en route air spaces. It also is used as input into aviat...
most scientists believe that the phenomenon of global warming occurred, however, in the case of the occurrence of this phenomenon by some environmental scientists have raised doubts. they are questioning global warming by arguing that the temperature recorded at the weather stations cannot be representative of the occurrence of the temperature rise. because with the passage of time and the incr...
Background: The role of temperature changes, as an environmental risk factor, in the human health status has been investigated in recent studies. Accordingly, the present two-year study was conducted to evaluate the incidence of myocardial infarction (MI) in warm and cold seasons in Ali-ibn Abi Talib Hospital, Rafsanjan, Iran. Materials and Methods: In this descriptive and cross-sectional st...
Forest structural diversity is related to stability, biodiversity, adaptability and resilience, as well productivity of forest ecosystems. In this study, we characterized the diverse type groups in southeastern Outer Coastal Plains Mixed Province United States. We utilized data from 13,658 Inventory Analysis (FIA) plots across region classified them on basis group (i.e., longleaf-slash pine, lo...
European framework for online integrated air quality and meteorology modeling (EuMetChem) focuses on a new generation of online integrated Atmospheric Chemical Transport (ACT) and Meteorology (Numerical Weather Prediction and Climate) modeling with two-way interactions between different atmospheric processes including chemistry (both gases and aerosols), clouds, radiation, boundary layer, emiss...
Habitual physical activity is an important determinant of health, yet many people are considered to be inactive. Identification of the obstacles to greater participation is necessary for the development of strategies to overcome those obstacles. The weather has been identified as a perceived barrier to participation in physical activity, but exactly which adverse weather conditions are most imp...
نگاشت های گویای استثنایی آن دسته از نگاشت های گویا هستند که نقطه ی تناوبی از هر دوره ی تناوب دلخواه نداشته باشند. ثابت شده است اگر نگاشت گویای r از درجه ی d ، نقطه ی تناوبی از دوره ی تناوب اولیه ی n نداشته باشد آن گاه {(d,n) ? { (2,2), (2,3), (3,2), (4,2) نگاشت های گویای استثنایی تحت تزویج های همدیس دسته بندی و مشخص شده اند. به عنوان مثال هر نگاشت گویای درجه ی 2 که فاقد مداری از دوره ی تن...
