Development And Experimental Verification Of A Three-Dimensional Model Of Left Ventricular Flow Dynamics, Tong Ding

FIU Electronic Theses and Dissertations

Ischemic heart disease, which results from the insufficient coronary artery blood flow is a leading cause of mortality in developed countries. It manifests itself by abnormal left ventricular wall motion during systole.

A three dimensional numerical model was developed to simulate the flow patterns in the left ventricle. Numerical solutions were obtained by discretizing the Navier-Stokes equations for viscous, incompressible, steady flow using finite element method.

A diagnostic index Central Ejection Region (CER) as well as its quantitative version CER coefficient which are based on the flow patterns were defined as the region in which velocity vectors were aligned 5 …

Mode Choice Modeling With Neural Network : Boston Area Case Study, Soon Chung

FIU Electronic Theses and Dissertations

Demand forecasting is an essential element in the analysis of transportation systems. It is concerned with the behavior of consumers of transportation services and facilities. We choose geographic, demographic, and socioeconomic characteristics of consumers that may affect the travel demand of each selected. We use an artificial neural network to predict travel demand with characteristics selected from three different database sources: Census Summary Tape files, TIGER/Line files, and Federal Transit Administration's National Transit GIS database.

A neural network is an information processing system that is intensely parallel and neural networks are capable of learning how to classify and associate input/output …
