Improving the Accuracy of the Diffusion Model in Highly Absorbing Media
The diffusion approximation of the Boltzmann transport equation is most commonly used for describing the photon propagation in turbid media. It produces satisfactory results in weakly absorbing and highly scattering media, ...
A General Formula for Fan-Beam Lambda Tomography
Electric Propulsion Plume Simulations Using Parallel Computer
A parallel, three-dimensional electrostatic PIC code is developed for large-scale electric propulsion simulations using parallel supercomputers. This code uses a newly developed immersed-finite-element particle-in-cell ...
Mathematical Study and Numerical Simulation of Multispectral Bioluminescence Tomography
Multispectral bioluminescence tomography (BLT) attracts increasinglymore attention in the area of optical molecular imaging. In this paper, we analyzethe properties of the solutions to the regularized and discretized ...
Nonrigid Medical Image Registration by Finite-Element Deformable Sheet-Curve Models
Image-based change quantitation has been recognized as a promisingtool for accurate assessment of tumor's early response tochemoprevention in cancer research. For example, various changeson breast density and vascularity ...
Vibration and Dynamic Response Control of Nonuniform Composite Rotating Blades
This paper addresses the free vibration, dynamic response, and theactive control of composite rotating pretwisted blades modeled asnonuniform thin-walled beams, fixed at the hub at a settingangle, and incorporating ...
