A Semi-Analytical Parametric Model for Dependent Defaults

A Simple Exponential Model for Dependent Defaults

A thorough understanding of the joint default behavior of credit-risky securities is essential for credit risk measurement as well as the valuation of multi-name credit derivatives and Collateralized Debt Obligations. In this paper we study a simple and tractable intensity-based model for correlated defaults, in which unpredictable default arrival times are jointly exponentially distributed. Si...

A Mean-Field Model for Dependent Defaults and Counterparty Risk

A semi-analytical model for velocity profile at wind turbine wake using blade element momentum

The shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. In reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a S-shape profile. Th...
