Integrated Multiscale Biomaterials Experiment and Modeling

Image Based Multiscale Modeling of Porous Biomaterials

Biomaterials are typical structures of poroelasticity in nature. Due to heterogeneous composition of microstructures, the asymptotic based homogenization was introduced to correlate the microscopic solid-fluid phase to the macroscopic balance laws. In this work, a microstructure informed computational method for modeling of porous biomaterials is developed. To construct microscopic models direc...

Integrated multiscale process simulation

We summarize two approaches to integrated multiscale process simulation (IMPS), particularly relevant to integrated circuit (IC) fabrication, in which models for equipment (m) and feature (lm) scales are solved simultaneously. The first approach uses regular grids, and is applied to low-pressure chemical vapor deposition (LPCVD) of silicon dioxide from tetraethoxysilane (TEOS). The second appro...

Multiname and Multiscale Default Modeling

Multiname default modeling is crucial in the context of pricing credit derivatives such as Collaterized Debt Obligations (CDOs). We consider here a simple reduced form approach for multiname defaults based on the Vasicek or Ornstein-Uhlenbeck model for the hazard rates of the underlying names. We analyze the impact of volatility time scales on the default distribution and CDO prices. We demonst...
