Dioxins and Human Health
Few environmental issues have attracted as much attention and controversy as the dioxins. Considerable expense has been incurred investigating effects in human populations and laboratory...
Risk Assessment and Public Policy
A governmental official charged with making solid waste policy should be careful not to allow the public policy issue to be defined as the determination of the acceptable level of risk...
The Swedish Dioxin Moratorium
Municipal waste constitutes an energy resource but also an environmental problem. In Sweden emissions of dioxines from waste-to-energy plants have triggered a major debate on environmental...
The National Incinerator Testing & Evaluation Program
Environment Canada, under the National Incinerator Testing & Evaluation Program (NITEP), is addressing emissions from municipal energy-from-waste combustion systems. The main thrust...
The Dioxin Situation in West Germany
The public discussion in Germany of the 'dioxin problem' has recently become more rational than it was three years ago. Emotions and hard facts are in a balance...
An Uncertainty Analysis Methodology Applied to Sheetpile Cofferdam Design
The input data to numerical simulation models is often uncertain, and, consequently, model predictions may be uncertain. Such uncertainties are often treated by Monte Carlo techniques....
Parametric Analysis of Concrete Gravity Dams using Finite Element Analysis
More sophisticated means of analyses have been investigated to determine the accuracy and applicability of conventional methods to a range of parameters affecting stability. This paper...
Mathematical Simulation of Halocarbon Distributions in Boston Harbor
In an effort to better understand the sources and transport of effluents, a combined modeling and field measurement program has been initiated. The modeling uses a pair of 2-D (depth-averaged)...
A Semianalytical Method for Solving Unsteady Flow Equations
This paper proposes a method that uses conjunctively the Laplace transform for continuous time and finite element for spatial discretization to solve unsteady flow equations. Laplace transforms...
Alternative Methods for Representing Sinkholes in Three-Dimensional Ground Water Flow Models
Two methods of representing the sinkholes in central Florida were investigated with a three-dimensional finite element model recently developed by Camp Dresser & McKee Inc. Both...
Numerical Model Analysis of Sedimentation Problems at Lock and Dam 1, Red River Waterway
This paper addresses the numerical modeling techniques used to identify the conditions and parameters affecting sediment deposition at Lock and Dam 1. Two-dimensional finite element models...
Computational Modeling of Sediment Transport in Kachemak Bay
The tide-generated flow circulation in the Kachemak Bay of Alaska was simulated numerically using the Multi-Leveled Finite Element Model originally developed by Kawahara of Japan and recently...
Low Head Hydropower Finite Element Analysis
Finite element analysis provides a means of predicting the flow conditions resulting from the operation of a proposed hydropower facility. The results of a finite element flow analysis...
Redundancy Evaluation of Existing Bridges
The redundancy of an existing bridge can only be correctly assessed by considering the full superstructure as a single entity. Any formulation based on the analysis of bridge components...
Feasibility Studies of Flood Warning-Response Plans
Local flood warning-emergency preparedness plans consist of hardware, technical activities, and formal and informal inter- and intra-organizational arrangements and commitments to performance...
Groundwater Quality Modeling at Redlands/Crafton Area
Organic groundwater contamination exists in the Redlands area of the Bunker Hill Groundwater Basin which is of major concern to the health and water agencies in the region. The contaminants...
Reliability of a Frictional System with Uncertainty
In recent years, more emphasis has been placed on the study of random vibration of structures with uncertain parameters. Most of these have dealt with second order statistics of the response...
Recent Developments of the Finite Strip Method
The finite strip method is approaching a state of maturity as a structural analysis technique, as the well known finite element method has done. Two comprehensive (although somewhat dated)...
Optimum Cut-Outs on Plate Stability
Cut-outs are unavoidable in some of the plate components. To minimize the plate weight, in the meantime, to maintain the critical buckling load as high as possible is one of the major...
Stability of Cylindrical Shells With and Without Cutouts and Subjected to Wind Load
The cylindrical storage tanks with and without cutouts are analyzed using nonlinear finite element analysis. All the cylinders are fixed at the base. Two types of cylindrical tanks without...
