Wind Power in Antarctica?Case Histories of the North Wind HR3 Wind Turbine
The combination of extreme weather conditons and remoteness of the Antarctic sites makes them even better suited for wind turbine installations since the alternative power sources are...
Wind Frame Design for Mid Rise Buildings
A brief discussion of drift limits is followed by design procedures for unbraced moment resisting wind frames and initial selection of optimized member sizes for chevron bracing frames....
Variation of Permeability with Temperature in Fractured Topopah Spring Tuff Samples
Fractures will play an important role in the near-field hydrology of a nuclear-waste package in a mined repository. Our previous studies showed that the water permeability of fractured...
An Alternative Method to Mariotte Reservoir System for Maintaining Constant Hydraulic Pressure
Several problems with the Mariotte reservoir system were discovered when it was used to apply a constant water pressure as a boundary condition for a prolonged period. The constant-pressure...
Structural Optimization to Limit Natural Periods
It is necessary to limit the natural periods of some structures to control their response to dynamic loads. Floor systems with natural periods greater than approximately 0.15 seconds may...
Rebuilding Buried Pipelines Without Digging
Advances and refinements in trenchless reconstruction technologies now permit system rebuilding of gravity and low pressure pipelines without excavation. Through the use of cured-in-place...
Optimizing Urban Ground Water Supply Systems
The cost of Pumping comprises a major part of total water operation and maintenance expenses. Most utilities attempt to keep these costs down. However, there are areas of study that may...
Sensitivity Analysis for the Numerical Evaluation of Wind Effects on Buildings
The paper describes the sensitivity analysis carried out in the computational evaluation of wind effects on buildings by using a computer code named TWIST - Turbulent WInd Simulation Techniques....
Wave Calculation Using WAM Model and NMC Wind
The CYCLE 2 version of the WAM (Wave Model) model is used to hinfcast global ocean wave spectra, using the NMC (National Meteorological Center) winds, for a period of about 60 days. The...
Gas Phase Turbulence Modification with Fine Particles in 2-D Duct Flow
The effect of a dilute suspension of fine particles on a two-dimensional turbulent duct gas flow is measured with hot-film anemometry. The flow field without particles is compared to the...
Hydrodynamic Pressure on an Oscillating Vertical Plate
The hydrodynamic pressure on an oscillating vertical plate could be influenced by the effects of compressibility of fluids and surface waves. The compressibility is effective for higher...
Computation of Wind Flow Around a Building
A numerical investigation of wind flow around a three-dimensional building is presented by solving weakly compressible flow equations, together with Smogrinsky's subgrid-scale...
Non-Linear Passive Elastic Properties of the Left Ventricular Myocardium: Application of Finite Element Analysis to 3-D Geometry Obtained from Ultrasound Images
A finite element (FE) analysis and an optimization algorithm were employed to assess the nonlinear passive elastic properties of left ventricular myocardium in a canine mode. The three-dimensional...
In-Vitro Measurement of Static Contact Pressure Distribution in Synovial Joints
The objective of this presentation is, at first, to review the various approaches to the measurement of contact pressure distribution in synovial joints, and then to describe the development...
Material Testing at High Pressure
A static test cell has been designed and fabricated to apply a peak stress of up to 2 GPa to a 2.54 cm cylindrical specimen. The cell design was based on the 'belt'...
Up and Down Construction of a 17-Story Building
The One Westwood Building is located on a small site in the Westwood district of Los Angeles. Construction of the 17-story building with 8 levels of subterranean parking was complicated...
Development of the South Carolina Coast 1959-1989: Prelude to a Disaster
The history of hurricanes on the South Carolina Coast is reviewed. It is shown that reasonable design wind and surge conditions could have been established before the rapid development...
Meteorological Aspects of Hurricane Hugo
Despite recent improvements in the accuracy of hurricane forecasting at a rate of about one-half to one percent per-year over the past decade, the population growth in coastal mainland...
Hugo 1989 - The Performance of Structures in the Wind
The performance of buildings in the Carolinas during Hurricane Hugo, 21-22 September 1989, is reviewed. Wind speeds in most locations were below the design levels specified in the local...
Hurricane Hugo vs Critical Lifelines
Hurricane Hugo significantly affected the performance of critical lifelines in South and North Carolina. An overview of the performance of power supply, transportation, communication,...
