abstract drought is a natural creeping event that starts due to lower moisture compared to normal condition. this phenomenon impacts all aspects of human activities. however there is neither any detailed definition nor a general and proper index for drought monitoring. in this study, fuzzy logic has been applied to deal with inherent uncertainties of the real world data. we presented a fuzzy mo...

in recent decades, neyshabour basin as a semi-arid climate has faced with dramatic increasing of groundwater withdrawal. so, water demand management is important in this basin. in this study, the effects of evapotranspiration and rainfall on groundwater fluctuations have been considered with 22 rain gage and evaporation gage station data during 1973-2006. the average amount of rainfall and evap...

BACKGROUND In both Sweden and Australia high incidence rates of skin cancer have become a major health problem. In prevention and risk communication, it is important to have reliable ways for identifying people with risky sun habits. In this study the validity and reliability of the questionnaire Sun Exposure Protection Index (SEPI), developed to assess individual's sun habits and their propens...

drought as a natural but temporary imbalance of water availability is the interaction between natural environment and human life resulting in diminished water resources availability and reduced carrying capacity of the ecosystems. drought indices are essential elements for an efficient drought monitoring system. these indices make the transforming information of climatic anomalies easier and al...

Recent research on the Symbolic Probabilis­ tic Inference (SPI) algorithm[;:] has focused attention on the importance of resolving general queries in Bayesian networks. SPI applies the concept of dependency-directed backward search to probabilistic inference, and is incremental with respect to both queries and observations. In response to this research we have extended the evidence potential al...

This article presents the dynamics and measurement of a relatively unstudied concept in children's and adolescents' suicidal behavior: the subjective experience of problem irresolvability (SEPI). This concept relates to the youngsters' sense of lack of control due to being pressured to resolve irresolvable problems within the family circle. The first study describes the construction and factor ...

introduction: drought is a recurrent feature of climate that caused by deficiency of precipitation over time. due to the rise in water demand and alarming climate change, recent year’s observer much focus on drought and drought conditions. a multiple types of deficits and relevant temporal scales can be achieved through the construction of a joint indicator that draws on information from multip...
