The goal of this study was to apply artificial neural networks to predict rain-fed wheat yield using meteorological data a few days to few months before harvesting. The climatic observation data used; were mean of daily minimum and maximum temperature, extreme of daily minimum and maximum temperature, sum of daily rainfall, number of rainy days, sum of daily sun hours, mean of daily wind speed,...

Drought is one of the phenomena that has recently been identified as a major challenge , and has incurred a lot of damage in different parts of the world. The purpose of this study was to investigate and map drought in Kermanshah Province using the CZI index in ArcGIS for 1995-2016 using data from synoptic stations of Kermanshah, Kangavar, Sahneh, Harsin, Mahidshah, Sararood, Paveh, Ravansar, S...

Iskander Aliev A sharp lower bound for the Frobenius number Ferdinand Georg Frobenius (1849–1917) raised the following problem: given N positive integers a1, . . . , aN with gcd(a1, . . . , aN ) = 1, find the largest natural number gN = gN (a1, . . . , aN) (called the Frobenius

In this study, in order to study the base temperature (minimum temperature for plant growth) at the degree of growth day (GDD), which is one of the important parameters in calculating the degree of growth day, first, the data required for the 2009-2017 statistical period of wheat production at the station Sararood was taken from the station. Then, after sorting and separating growth different s...
