introduction climate affects, more than any other factors, the type and form of human life, so that many cities that have made or developed regardless of climatic information are suffering from weather-related problems such as air pollution, water supply and flooding etc. by using the meteorological information in designing new cities as well as developing old cities can reduce the mentioned pr...

An attack on the implementation of control vectors in the IBM Common Cryptographic Architecture is presented. The final key−part holder in a multiple part import introduces two key−encrypting keys (KEKs), one the intended key and one with a chosen difference from the former, by including this difference in his own key part. When this difference is set to the difference between two control vecto...

This study attempts to quantify the relative contributions of vegetation greening in China due to climatic and human influences from multiple observational datasets. Satellite measured vegetation greenness, Normalized Difference Vegetation Index (NDVI), and relevant climate, land cover, and socioeconomic data since 1982 are analyzed using a multiple linear regression (MLR) method. A statistical...

Aim. To study the effect of climate changes on performance cereals. Methods. Remote, statistical, and analytic methods. Climate were determined by sum radiation temperatures earth’s surface, calculated using data infrared range (10.3–11.3; 11.4–12.4 μm) high precision radiometer AVHRR meteorological satellites Earth, NOAA. The state vegetation, including phenological parameters, such as beginni...

climate change is defined as long term and irreversible changes in the climatic behaviorof a region. many studies have been conducted in different regions of the world on climatechange. the results of these studies show considerable changes in climatic factors especiallyin precipitation and temperature. in this research, the trend of changes in annual and seasonalrainfall and temperature in 24 ...

food security in the world that water shortages are faced is very important, especially in arid regions. effects of climate change on agricultural water requirement have doubled this importance. in this study, the risk of water demand has been assessed for a wide range of products under climate change. aogcm models have been used to simulate climate variables. the climate change scenarios of cl...

In agroecosystems, drought is a critical climatic phenomenon that affects evapotranspiration and induces water stress in plants. The objective this study was to characterize forecast the Hyderabad region of India using artificial intelligence models. monthly precipitation data for period 1982–2021 characterized by standardized index (SPI) modeled classical autoregressive integrated moving avera...
