based on spi and rdi indices, changes in droughts in the semi-arid areas of west golestan province was assessed in the gis environment by incorporating data from hashemabad synoptic station and 11 climatic stations. after evaluating the ability of lars-wg5 in the simulation period (1984-2010), downscaling of hadcm3, ipcm, and gfc models was done as a group under scenarios of a1b, a2 and b1 to e...

In this paper we describe an approach for reasoning about typicality and defeasible properties in low complexity preferential Description Logics. We describe the non-monotonic extension of the low complexity DLs EL and DL-Litecore based on a typicality operator T, which enjoys a preferential semantics. We summarize complexity results for such extensions, called EL⊥Tmin and DL-LitecTmin. Entailm...

To apply branch-and-bound algorithm to minimize the quality function (6) in the main paper, we first specify the spaces where Ts and Te may take a value. We denote the length of the shortest exemplar activity as Tmin, then we assume 1 ≤ Ts ≤ T − Tmin + 1 and Tmin + 1 ≤ Te ≤ T . Additional constraint may be imposed, such as Tmin ≤ Te − Ts. Given these information, the temporal branch-and-bound a...

yield prediction before harvesting is one of the tools in order to planning food production supply in future.yield prediction was carried out for wheat(triticum aestivum) using different meteorological variables with agrometeorological indices in hamedan district during 2003-04 and 2004-05. according to correlation coefficients, standard error of estimate as well as relative deviation of predic...

The aim of the study was to investigate utility artificial neural networks (ANNs) for estimation reference evapotranspiration (ETo) on Peloponnese Peninsula in Greece two representative months wintertime and summertime during 2016–2019 test if using fewer inputs could lead satisfactory predictions. Datasets from sixty-two meteorological stations were employed. available mean temperature (Tmean)...
