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, ...

building on previous studies on the effectiveness of different types of written corrective feedback, the present study aimed at investigating whether direct focused corrective feedback and direct unfocused corrective feedback produced any differential effects on the accurate use of english articles by efl learners across two different proficiency levels (low and high). in current study, the par...
New inclinometers devoted to hydrological studies were set up in the Vosges Mountains (France). Two orthogonal 100-meter base hydrostatic inclinometers were installed in December 2004 as well as a hydrometeorological monitoring system for the 100-km2 hydrological unit around the inclinometer. As inclinometers are very sensitive to environmental influences, this observatory is a test site to con...
the term hydrological drought is applied to represent low water levels in streams, reservoirs and lakes as well as a low groundwater level. base flow index (bfi) as one of low flow indices gives the ratio of base flow to total flow and investigates basin’s ability to store and release of water in drought periods. the objectives of this study were to determine bfi and to validate this index in d...
The current practices used in tube drainage design often lead to unsatisfactory results : from the point of view of the system's hydraulic performance, or from the point of view of high cost of the system in relation to the actual economic benefits derived from it. It is proposed therefore, that the design of tube drainage systems should be based on a synthesis of experimental field results, an...

In present investigation, aging coefficient (A.C.) was stidied and compared in some different provinces of Iran, according to their most important geographical conditions such as altitude. Study of climatological profile of North-West to South-East of Iran shows gradual decrease of altitude as well as climatological profile of the west to the east of Iran. Results show that A.C increase gra...
