abstract   disease mapping includes a set of statistical techniques that lead to provide clean maps based on estimation of the incidence, prevalence and mortality rates for the users to be able to estimate the distribution of disease reliably. the main aims of disease mapping are to: describe the spatial variation in disease incidence for the formulation of etiological hypotheses; identify area...

insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...

in developing and newly industrialized countries, population growth and migration contribute immensely to the development of megacities and mega urban areas. in most cases, the rapid development ofcities has far-reaching consequences for the ecosystem in general and the hydrological cycle in particular. the developments in china within the last decades show an interesting, but complex setting. ...

Background: Congenital Hypothyroidism (CH) is one of the reasons for mental retardation and defective growth in neonates. It can be treated if it is diagnosed early. The congenital hypothyroidism can be diagnosed using newborn screening in the first days after birth. Disease mapping helps to identify high-risk areas of the disease. This study aimed to evaluate the pattern of CH using the Poisso...

Background & objective: Due to the features such as intuitive graphical appearance, ease of perception and straightforward applicability, risk matrix has become as one of the most used risk assessment tools. On the other hand, features such as the lack of precision in the classification of risk index, as well as subjective computational process, has limited its use. In order to solve this pro...

Drought is one of the main and significant factors that increase the potential risk of fire in forests and rangelands. This study was conducted to assess the potential of a soil-moisture index called Keetch-Byram Drought Index (KBDI) for mapping fire risk in the forests and rangelands of Isfahan province using daily climate data in 2006- 2010 period. KBDI is a drought/fire index that ranges fro...
