Cerebral vasospasm is a complication of subarachnoid hemorrhage and other neurosurgical emergencies that reduce blood flow to the brain. Part of the approach to management of vasospasm is to improve flow through the stenotic areas by reducing by decreasing blood viscosity and enhancing flow through the stenosis. To examine the interaction of these factors, we applied computational fluid ...

Photodynamic therapy(PDT) is a new cancer treatment modality using the photochemical reaction of a photosensitizing drug, light, and oxygen. The objective of this project is to determine the photochemical parameters necessary for singlet oxygen modeling during PDT using parameters obtained from a microscopic model. FEM calculation in COMSOL Multiphysics was used to determine the model ...

RFSP-IST (Reactor Fueling Simulation Program) is a computer code used for the full-core neutronics design and analysis of CANDU® reactors. RFSP-IST calculates the static flux and power distributions in the core by solving the neutron diffusion equation in two energy groups. For validation purposes, results from RFSP-IST are often compared with those from other codes. This paper documents the ...

In this presentation, “Design and Analysis of MEMS-based direct methanol fuel cell,” there are three main model parts, two-dimensional two-phase mass transport model, μdmfc three-dimensional model and a novel cathode model. First, a two-dimensional two-phase mass transport model was established. In this model, the process of gas-liquid transfer and electrochemical reaction within the μ ...

Magnetoacoustic tomography with magnetic induction (MAT-MI) is a recently introduced method for imaging electrical impedance properties, which integrates classic electrical impedance tomography and ultrasonic technique. It could provide an explicitly reconstructed electrical impedance distribution with high spatial resolution and contrast, eliminating the shielding effects of insulating tissues. ...

Fluids used in biomedical microelectromechanical systems (BioMEMS) devices often exhibit very different flow behavior from those in bulk solutions, which in turn affects the behavior of cells and biomolecules in the device. In this work, we investigate an integrated microfluidic system for living cell culture and assay. The system can be used as a generic platform to study the behavior of ...

In this paper, we develop a mathematical model to simulate the movement of bacteria into and within a capillary segment. Also, we model the transportation through capillary walls by means of anisotropic diffusivity that depends on the pressure difference across the capillary walls. By solving the model using COMSOL, it was possible to predict the concentration of bacteria at points within the ...
