A Short-Term Demand Forecasting Model from Real-Time Traffic Data
Developing real-time traffic diversion strategies is a major issue of Advance Traffic Management Systems (ATMS), a component of Intelligent Vehicle Highway Systems(IVHS). Traffic diversions...
Lifelike Model
Data from about 400 structures in the San Francisco Bay Area were recorded during the 7.1 Richter-scale Loma Prieta quake. Among these structures was a 49-story office tower in downtown...
Marsh Submergence vs. Marsh Accretion: Interpreting Accretion Deficit Data in Coastal Louisiana
The apparent imbalance between relative sea-level rise and vertical marsh accretion is frequently cited as a major factor in the problem of wetland loss in Louisiana. Rates of relative...
Study of the Circulatory and Salinity Changes in Galveston Bay, Texas by Using a Three-Dimensional Hydrodynamic and Transport Model
The effects of tides and freshwater inflows on the circulation and salinity changes in Galveston Bay are investigated numerically by using three-dimensional hydrodynamic and transport...
