Introduction In the last few years the quantitative modelling of credit risk has received a lot of attention within the financial industry. Several models have been released to the public, notably CreditRisk+, CreditMetrics, Credit Portfolio View [CR97, CM97, CP98]. Although different approaches to credit risk are used, studies have shown that the models yield similar results if the parameters ...

In recent decades many researchers have studied on the damage assessment of structures after a seismic event. To assess the damage of structures under an earthquake, it is so important to study the correlations between earthquake parameters and damages of the structures. A lot of seismic parameters have been defined by researchers to characterize an earthquake. Spectral parameters of an earthqu...

measurement of bose-einstein correlations in the production of like-signed pion pairs has been made with the amy detector at tristan. an event sample of 10120 hadronic events with ranging between 50 to 61 gev was used. these measurements indicate a strength of the enhancement of ? = 0.61m.07, with a typical correlation size of ro = 1.16±.08 fm. this value of ? is consistent with measurements at...

aim : to assess the clinical characteristic of cd as well as correlation of symptoms and the degrees of intestinal mucosal lesions in iranian children. background : microscopic enteritis (marsh 0-ii) is associated with malabsorption. patients and methods : from august 2005 to september 2009, 111 cases with malabsorption and classical gastrointestinal symptoms were evaluated. results : the mean ...

Numerous empirical correlations exist for the estimation of crude oil viscosities. Most of these correlations are not based on the experimental and field data from Iranian geological zone. In this study several well-known empirical correlations including Beal, Beggs, Glasso, Labedi, Schmidt, Alikhan and Naseri were optimized and refitted with the Iranian oil field data. The results showed that ...
