GPR propagation simulation and fat dipole antenna design
… ground media. Results of the ground penetration simulations done in FEKO (MoM- Method of Moment) is compared to Finite Difference Time Domain (FDTD) results simulated by Mukhopadhyay with the same physical model. The second application is to model and fabricate an ultra wide-band antenna with …

A SYSTEM ARCHITECTURE FOR THE INTEGRATION OF SMOKE PROPAGATION SIMULATION, EVACUATION SIMULATION, AND BUILDING INFORMATION MODELING
… architecture was designed to integrate smoke propagation simulation, evacuation simulation, and Building Information Modeling (BIM). The integrated software prototype automates the majority of the simulation workloads, enabling seamless data _ow from BIM to smoke propagation simulation and …

ESTIMATING PERFUSION AND VASCULAR PROPERTIES FROM MEDICAL IMAGES: QUANTITATIVE TRANSPORT MAPPING (QTM)
… after contrast agent injection, contrast agent propagation and underlying blood perfusion parameters can be estimated.This thesis developed a fast and accurate tracer propagation simulation method based on underlying fluid mechanics, as well as an inversion method that can recover perfusion …

Iterative nonlinear beam propagation method and its application in nonlinear devices
In this thesis, an iterative nonlinear beam propagation method is introduced and applied to optical devices. This method is based on Hamiltonian ray tracing and the Wigner distribution function. First, wave propagation simulation using Hamiltonian ray tracing is illustrated and verified with …

The response of the Red Sea to a strong wind jet near the Tokar Gap in summer
… there is some evidence for slow eastward propagation—simulation of the dipole in an idealized high-resolution numerical model suggests that this is the result of self-advection. These and other recent in situ observations in the Red Sea show that the upper ocean currents are dominated by …

Concurrently coupled multiscale modeling of polymer nanocomposites
… coupling developed to perform simulations of crack growth in polymers is presented. The presence of the continuum domain surrounding the MD region allows for the application of far-field loading, and prevents stress wave reflections from the external boundary impinging back on …

Passive Acoustic Mapping of Microbubbles in Focused Ultrasound Induced Brain Therapies for Preclinical Studies
… construct a receive array. An initial ultrasound-propagation simulation study was conducted to optimize the sparse array layout for both transmit and receive. A 256-element sparse hemispherical array (diameter = 100 mm) was constructed by assembling 128 PZT cylinder transmitters (resonance …

A Database Supported Modeling Environment for Pandemic Planning and Course of Action Analysis
… the historic epidemic data, computational simulation of epidemic propagation processes and disease control strategies can help us understand the spatio-temporal dynamics of epidemics in the laboratory. Consequently, the public can be better prepared and the government can control future …

Laser-induced heating, phase-shift, and damage : measurements and simulations
… parameters that were used experimentally. The simulation was also used to compute axial temperature for various power levels, beam diameters, and pulse durations. Laser-induced optical pathlength modulation or phase-shift was computed to study the thermal lensing effect. Power and irradiance …
