this thesis is a study on insurance fraud in iran automobile insurance industry and explores the usage of expert linkage between un-supervised clustering and analytical hierarchy process(ahp), and renders the findings from applying these algorithms for automobile insurance claim fraud detection. the expert linkage determination objective function plan provides us with a way to determine whi...
isfahan wild sheep ovis orientalis isphahanica is listed as vulnerable in the iucn red list of threatened species. adequate knowledge on habitat requirements and environmental factors determining the niche of a species is central to its conservation programmes. however, there is scarcity of data on habitat associations of this species in iran. a gis-based model, using presence-only data, was us...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
regarding the ever evolving and improving world on different aspects of knowledge, the need to a worldwide communication would emerge stronger than ever before which calls for special attention on the judgments and best choices for intermediating between the nations. as the language skills for translation are tested separately from translation skills themselves, to assess translation skills pro...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
A GIS multivariate model based on the Mahalanobis distance statistic is proposed to evaluate habitat suitability for the wolf Canis lupus in northern Spain. Results derived from the model show that wolves can potentially thrive in some habitats on the southern and western side of the study area where conflicts with the human population are minimum. However, some other areas that have been recen...
One way that climate change will impact animal distributions is by altering habitat suitability and habitat fragmentation. Understanding the impacts of climate change on currently threatened species is of immediate importance because complex conservation planning will be required. Here, we mapped changes to the distribution, suitability, and fragmentation of giant panda habitat under climate ch...
the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
All four chimpanzee sub-species populations are declining due to multiple factors including human-caused habitat loss. Effective conservation efforts are therefore needed to ensure their long-term survival. Habitat suitability models serve as useful tools for conservation planning by depicting relative environmental suitability in geographic space over time. Previous studies mapping chimpanzee ...
Predicting the potential distribution of plants in response to climate change is essential for their conservation and management. This study aimed at predicting the effect of climate change on the geographical distribution of Pistacia atlantica in Chaharmahal & Bakhtiari province in the central Zagros region. In this study, we used 19 Bioclimatic variables derived from rainfall and temperature ...
