Strangeness Production Incorporating Chiral Symmetry
Chiral symmetry is known to be decisive for an understanding of the low energy sector of strong interactions. It is thus important for a model of relativistic heavy ion collisions to incorporate the dynamical breaking and restoration of chiral symmetry. Thus we study an expansion scenario for a quark-meson plasma using the Nambu{Jona-Lasinio (NJL) model in its three avor version. The equations ...

15 صفحه اولIncorporating Event Risk into Value-at-Risk
Event risk is the risk that a portfolio’s value can be affected by large jumps in market prices. Event risk is synonymous with “fat tails” or “jump risk”. Event risk is one component of “specific risk,” defined by bank supervisors as the component of market risk not driven by market-wide shocks. Standard Value-at-Risk (VaR) models used by banks to measure market risk do not do a good job of cap...
متن کاملOptimisation of Steel Production Incorporating Economic Factors
Over the last four years efforts have been devoted towards the development and validation of mechanical test result models relating to a range of alloy steels. Several neural-network based models have been developed, two of which are related to the mechanical test results of Ultimate Tensile Strength (UTS), Reduction of Area (ROA), Elongation, etc. The ultimate aim of developing these models is...
متن کاملThe Analysis of Taiwanese Bank Efficiency: Incorporating both External Risk and Internal Risk
In this study, we adopt a three-stage approach, DEA method, Frontier regressions, and DEA method to estimate bank efficiency based on information obtained from 29 banks in Taiwan for the period from 2002 to 2004. In the first stage, we employ super SBM (super Slacks-Based Measure) to estimate the scores relating bank efficiency including internal risk. In the second stage, a stochastic frontier...
