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, ...
Abstract Millets are important agricultural crops for arid regions due to short life span and their resistance to salinity and drought conditions. In Iran, three main species of millets including proso millet (Panicum miliaceum), foxtail millet (Setaria italica) and pearl millet (Pennisetum glaucum) are cultivated in Shouthern Khorasan province, eastern Iran. In order to assess inter-specific...
the purpose of this study is to investigate the relationships between teachers’ immediacy behaviors and iranian students’ willingness to talk in english classes. analysis of the results from willingness to talk scale represents a relatively high level of willingness to talk in english classrooms among iranian language learners. the total mean score of students’ willingness to talk was 66.3 ou...
Cargo terminals are the gateways for entrance of commodities into the transportation network. Therefore, locating them in optimal location could have a major impact on the cost effectiveness and efficiency of transport, traffic safety and reduction in environmental pollutions. Due to the presence of a large number of parameters involved and the existing uncertainties, decision making in this fi...
Several saffron ecotypes (Mashhad, Torbat-Jam, Torbat-Haydarieh, Gonabad, Birjand, Ghaen) were evaluated in Urmia for stigma yield and yield components using different maternal corm weights(6, 8, 10, 12 g) in 2013 cropping year. The experiment was arranged as factorial based on randomized complete block design. Analysis of variance showed that there were significant differences among saffron ec...
Perturbed physics experiments are among the most comprehensive ways to address uncertainty in climate change forecasts. In these experiments, parameters and parametrizations in atmosphere-ocean general circulation models are perturbed across ranges of uncertainty, and results are compared with observations. In this paper, we describe the largest perturbed physics climate experiment conducted to...
This manuscript assesses climate change impacts to the North Sea and Baltic Sea using the regional bio-physical model ECOSMO forced by output from three CMIP3/A1B and three CMIP5/RCP4.5 global Earth System Models (ESMs). The main findings of the manuscript are similar to those of previous studies. However, the paper is poorly organized and not all the necessary information is presented. It is n...
Projected changes in emissions and climate will impact future air quality and related human and environmental health. In this work, an advanced online-coupled meteorology and chemistry model, the Weather Research and Forecasting Model with Chemistry (WRF/Chem), has been applied to the continental U.S. for current (2001–2010) and future (2046–2055) decades under four emission/ climate scenarios ...
انرژی مصرفی نه تنها خود تولیدکننده گازهای گلخانهای است؛ بلکه میزان مصرف آن جهت گرمایش و سرمایش محیط نیز تحت تأثیر تغییرات اقلیم و گرمایش جهانی ناشی از گازهای گلخانهای است. هدف از این پژوهش پیش بینی نیاز سرمایش استان فارس در دهههای آینده است. این پژوهش با استفاده از دادههای گردش کلی جوّ eh5om واکاوی شد. دادهها تحت سناریو a1bکمیته بینالمللی تغییر اقلیم و با تفکیک 75/1 درجه طولی و عرضی اجرا...
This article describes a climate change and hydrological impact assessment for several basins in Georgia. First, a new statistical technique, Joint Variable Spatial Downscaling (JVSD), is developed to produce high resolution gridded hydrological datasets for the Southeast US from 13 different Global Circulation Models (GCMs). A lumped conceptual watershed model (Georgakakos et al., 2010) is the...
