Intersection Air Quality Analysis
Methods of carbon monoxide concentration estimation at or near intersections have recently undergone scrutiny with resulting debate on the proper and accurate ways to make these estimates...

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...

Session Summary‚ÄĒBehavioral, Social, and Institutional Aspects of Risk Analysis

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...

Quantifying Uncertainty in Site Characterization
The uncertainties in determining the true geologic conditions at the proposed high-level nuclear waste repository at Yucca Mountain, Nevada needed to be determined as part of the Exploratory...

Inspection Planning for Surface Fatigue Cracks
A reliability based method for planning of inspections to detect surface fatigue cracks is presented. Cracks are described as semi-elliptical surface cracks. The conditions governing fatigue...

Reliability of Controlled Structures Subject to Real Parameter Uncertainties
This paper presents a systematic and probabilistically consistent approach for determining the likelihood that instability will result from the uncertainty inherently present in a controlled...

Structural System Design under Uncertainty Via Pareto Optimization
Structural systems are generally designed under safety, serviceability and economy requirements. The single objective optimal design problem of both deterministic and nondeterministic...

Stochastic Simulation and Optimization of Irrigation Canal Network Flows
This paper investigates the effects of parametric and objective uncertainty on simulation and optimal hydraulic design of irrigation canal networks. A model of spatially-varied flow in...

An Approach for Incorporating Inflows Uncertainty in Management Models
Inflow uncertainty is probably the most difficult issue for optimal management of conjunctive use water resources systems. In many instances, the effect of future inflows and their uncertainty...

Uncertainty and Sensitivity Results for Pre-Waste-Emplacement Groundwater Travel Time

Analysis of Uncertainty in Geotechnical Site Investigations, and Why

Methodology for Evaluating Dredged Material Alternatives Using Risk-Cost Analysis Under Uncertainty
A methodology and a case example was presented at the 1989 Conference on Risk-Based Decision Making in Water Resources, Santa Barbara, to perform risk-cost analysis for dredged material...

Some Remarks on BK-Models for Fatigue Crack Growth
The choice of a model parameter for concentrating the entire uncertainties of a constant load amplitude fatigue crack growth process is shown to be sufficient when reproducing the first...

Evaluating Advanced Technologies for Acid Rain Compliance
Technological innovation in emissions control of acid rain precursors has made possible increasingly stringent control requirements for coal-fired power plants. A key challenge for potential...

First Update to the U.S. Nuclear Regulatory Commission's Regulatory Strategy for the High-Level Waste Repository Program
The U.S. Nuclear Regulatory Commission (NRC) staff has updated its initial regulatory strategy for the High-Level Waste Repository Licensing Program. The update describes changes to the...

Transportation Access to Yucca Mountain: Critical Issues
Transportation planning for a repository at Yucca Mountain is complicated because of uncertainty about the modes and numbers of nuclear waste shipments and because of uncertainty about...

Performance Assessment: The Bridge Between Regulatory Decision-Making and Scientific Uncertainties
NRC has the responsibility for evaluating the license application for a repository against the regulations it has promulgated. Performance assessment is the bridge between regulatory decision-making...

Key Scientific Issues for Near-Field Performance Assessment
This paper reviews key scientific issues related to the performance assessment of engineered barrier systems. In contrast to the inherent uncertainties associated with inhomogeneous geologic...

Some Conclusions from a Biospheric Model Validation Study (BIOMOVS)
BIOMOVS (BIOspheric MOdel Validation Study) is an international co-operative effort to test biospheric models designed to calculate the environmental transfer and bioaccumulation of radionuclides...
