Evaluation of Modelling Parameters for Simulation of Estuarial Systems
Frequently, the purpose of flow simulation in estuaries and complex river systems is to develop circulation patterns for later use. In particular flow and stage time histories are required...

Pollutant Transport Modelling in Large River Plumes
The Niagara River plume in Lake Ontario and the Fraser River plume in the Strait of Georgia are of similar spatial dimensions, and arise from rivers with comparable discharge. Both rivers...

Innovative Reregulation Weirs
Since their construction, hydropower dams have generated more than just power for the Tennessee Valley Authority, they also generated concerns about their effects on river flow and aquatic...

Lunar-Based System to Supply Power to Earth: Summary of Concept, Benefits, and Development
The Lunar Power System (LPS) is described, references are given to other published work, and possibilities for demonstrating LPS are outlined. Analyses indicate that LPS can provide inexpensive...

Computer Modeling of Structural Systems for Residential Scale Buildings
The majority of housing in the United States is single family residences or low-rise multiple family dwelling units. The structural systems usually consist of rather uncomplicated types...

Travel Markets: An Approach to TCM Effectiveness Evaluation
This discussion paper describes a new approach to TCM evaluation using a travel market concept to classify trip types based on expected elasticities to various TCMs. Conventional trip...

GIS for Transportation and Air Quality Analysis
Geographic Information Systems (GIS) promise significant potential to manage complex spatial data often required to address transportation and air quality analysis problems. However, this...

Evaluating the Effectiveness of Transportation Control Measures for San Luis Obispo County, California
The San Luis Obispo Air Pollution Control District has developed simple techniques to estimate emission reductions from various Transportation Control Measures. Accurate emission estimates...

In-Use Emissions with Today's Closed-Loop Systems
Closed-loop emission control systems were adopted by most motor vehicle manufacturers on a wide-spread basis in model year 1981, in order to meet the 1981 and later Federal exhaust emission...

Climatic Change and Ensuing Risks Facing Water Resources Managers
Global climatic changes will have a significant effect on the utilization of regional water resources and will influence markedly the operation and management of water storage and delivery...

Quantitative Risk Assessment and Technology Transfer: Software Developments
A risk-based adaptation of the hydroeconomic model for estimating the expected annual damages of floods is presented in a spreadsheet environment. The model demonstrates how commercially...

Aversion to Epistemic Uncertainties in Rational Decision Making: Effects on Engineering Risk Management
When faced with epistemic uncertainties in a decision problem, subjective expected-utility theory (SEU) implies that the only relevant characteristic of these uncertainties is the mean...

On Deciding Between the Use of Engineering Standards and Risk Analysis
Risk analysis offers advantages for the optimal design and maintenance of infrastructure, but it is not always practical to apply due to the nature of certain types of infrastructure....

System Engineering and Risk
System engineering means many things to many people, but there is a large group of practicing engineers in the defense and energy sectors who define system engineering as a structured...

Optimal Allocation of Resources in Repair and Maintenance of Bridge Structures
The structural design process, examined in its entirety (and taking into account the uncertainty and randomness that characterize the governing parameters) is a decisional process, involving...

Implementing Uncertainty Treatment in AI Development Environment
The seismic vulnerability of existing masonry buildings is investigated by an expert system prototype. Field inspectors have to provide answers which can be of a Boolean, fuzzy or probabilistic...

A Probabilistic Regional Damage Estimation Model for Earthquake Occurrences
In this paper we present a model for estimating regional earthquake damage. The model utilizes the relational data base management system ORACLE and the geographic information system ARC/INFO...

Fuzzy Measures in the Knowledge Based Diagnosis of Seismic Vulnerability of Masonry Buildings
Rules based expert systems and fuzzy logic have been employed to increase the speed and the reliability of the survey of masonry buildings, to forecast their seismic vulnerability....

Response Variability and Reliability of Plates Using the Weighted Integral Method
A methodology is introduced to perform both the response variability and reliability analysis of two-dimensional stochastic systems (specifically plates subjected to plane stress or plane...

Stochastic Finite Elements and Reliability Analysis
A general - purpose approach for assessing the reliability of a nonlinear mechanical system under stochastic conditions was presented in (Faravelli, 1991). It combines the skeleton of...
