Wind-Induced Vibrations of Tall Buildings Using Tuned Mass Damper
A Lagrange formulation is applied to tall buildings using tuned mass damper. The resulting equations of motion are analyzed using a frequency window method. The method reduces the computational...

Effect of Lead Shielding on Small Cask Criticality
A study was performed to evaluate gamma shield effects on criticality safety for two modern legal weight truck casks. The lead gamma shield of a small spent fuel shipping cask increases...

The Effect of Gamma Irradiation on the Volatility and Redox State of Simulated DWPF High-Level Nuclear Waste Glasses
Gamma-induced volatility of simulated DWPF high-level nuclear waste glasses is highly dependent upon the redox state of the glass. For oxidized glasses with an Fe2+/(Fe2+...

A Rezoning Procedure for Finite Element Analysis of Rubber-like Materials
In this paper, we propose a rezoning procedure for finite element analysis of rubber-like materials. Rezoning procedures connect the distorted mesh and the newly created and undistorted...

Using Finite Element Analysis to Derive the Coefficient of Subgrade Reaction
The coefficient subgrade reaction is a concept used to generate spring constants which are commonly used to model the foundation subgrade in the analysis of mat foundations. This paper...

Plastic Limit Analysis of Arch Dams
This paper applies the lower- and the Upper- bound theorems of the plasticity theory to arch dams, according to different forms of discretization for dam, two methods, namely the structural...

Adapting Conceptual Clustering for Preliminary Structural Design
The use of conceptual clustering for knowledge acquisition can facilitate the development of a knowledge base in a domain where little formalized knowledge is really available. The limitations...

Measuring the Effect of Sediment Fences for Wetland Creation and Restoration in Louisiana
A sediment erosion table (SET) method has been developed to monitor changes over time in intertidal mudflat or pond elevations with an accuracy in the 1.5 mm range. The SET permitted rapid...

Trace Metal Distribution in the Sediments of the Bight of Bonny, South Eastern Nigeria
Coastal sediments are important hosts for pollutant trace metals. The concentration and distributions of heavy metals depend on factors such as grain size of sediments, availability and...

Aiming at Port and Harbour Technology Mild to Human Beings and the Earth
The ports and harbors bureau of the ministry of transport formulated and announced a long-term port and harbor development policy, ports and harbors toward the twenty-first century aiming...

Temporal Variation of Precipitation Trend at Seoul, Korea, 1771-1991
This paper describes temporal variation of annual precipitation trend from 1771 to 1991 at Seoul, Korea. Analysis of the series shows no distinct trend over years. A linear trend would...

Unit Hydrograph Estimation Procedures Using Orthogonal Functions
All unit hydrograph estimation procedures based on orthogonal functions are reviewed in this paper. A more physically based orthogonal function (a gamma function) for unit hydrograph estimation...

Probabilistic Characteristics of Elapsed Time Between Rainfalls
The elapsed time between rainfalls is analyzed statistically using the hourly rain data at two locations: the flat-plain at Urbana, Illinois and the northwestern Appalachian foothills...

Analysis of Spatial and Temporal Precipitation Data Over a Densely Gaged Experimental Watershed
Historical precipitation data from the densely gaged Walnut Gulch Experimental Watershed in southeastern Arizona are used to quantify watershed-scale properties of precipitation. Daily,...

Measuring Soil Bulk Density Profiles with a Single Probe Gamma Density Gauge
Calibrating neutron depth gauges for measuring soil water content profiles requires soil bulk density data. In this study, the feasibility of using a single probe gamma density gauge to...

Selective Withdrawal in a Rotating Stratified Fluid
In this paper we consider the axisymmetric flow of a rotating stratified fluid into a point sink. Linear analysis of the initial value problem of flow of a linearly stratified fluid into...

Optimizing Water Transfers in Urban Water Supply Planning
A number of water supply agencies in the Western United States have begun to integrate water transfers into their overall water supply planning, including the use of transferred water...

Gas Pipeline Fitness-for-Service Investigation
A delta reclamation district's plan to add significant fill on their levee caused great concern for the integrity of a critical PG&E 22-inch (559 mm) gas transmission line which...

Comparison of Maximum Efficiencies in a Cross-Flow Turbine

3-D Deformation Analysis of Pile Groups During Wave Loading
Deformation predictions of pile group supporting one leg of Magnus platform were conducted using the 3-D nonlinear computer program SPLICE (Structure/Pile/Soil Interaction Analysis) and...
