Economic factors of Wave Energy Conversion
The paper provides some insights into the institutional setting in which power marketing is conducted (in the United States). It presents some approaches to economic evaluation that might...

Wave Energy Research in Ireland
Measurements taken at several locations off the Irish coast show that the average power intensity available to Ireland well exceeds 20 kW/m. Several projects have been undertaken in an...

On the Performance of a Wave Power Converter
This paper presents the KN-principle for wave - power conversion. The principle and components of the wave power converter are described and some practical relations are presented in order...

Optimal Strategies for Phase Control of Wave Energy Devices
Phase control has previously been proposed for increasing energy output from wave power devices, and latching strategies have been tested for point absorbers and for pneumatic devices....

Selected Papers from the Chinese Journal of Geotechnical Engineering ?1985
This book contains English translations of 19 articles selected from the Chinese Journal of Geotechnical Engineering. Five of the papers are...

Utilization of Ocean Waves?Wave to Energy Conversion
This collection of papers reviews both the state of the art in pneumatic wave energy conversion and the associated peripheral technologies, such as capture chamber research and design,...

Ocean Energy: Can It Compete?
Electric power plants using ocean energy are technically viable, but they tend to be cost-prohibitive. A study commissioned by the Electric Power Research Institute and carried out by...

Laser-2-Focus Flow Measurements in the Runner of a Bulb Turbine and Comparison with Calculation
Flow measurements are presented, which were carried out near and inside the 4-blade runner of an axial model bulb turbine of double adjustable type. These measurements were performed by...

Index Testing?Relative Turbine Performance
The Index method of testing hydraulic turbines consists of making a test in which the value of power output and head are measured and in which the quantities of water and velocity head...

Artificial Ice Islands for Deep Water and Production Structures
The need for an island to survive the summer melt season is introduced. To account for surface melting and erosion from waves and currents during this season, the island's...

Wave Forces on an Arctic Monotower Platform
At offshore lease sites located along the western coast of Alaska, longer periods of open water can be expected. As a result, wave induced hydrodynamic loading will become a more significant...

Landslide Dammed Lakes at Mount St. Helens, Washington
The collapse of the north face of Mount St. Helens on May 18, 1980, and the debris avalanche that resulted blocked outflow from Spirit Lake and Coldwater and South Fork Castle Creeks....

Importance of Phasing of Strong Ground Motion in the Estimation of Structural Response
In this paper, the influence on Fourier phase spectrum of seismic source directivity due to rupture propagation along the earthquake source is investigated. The phasing is described using...

Floating Bridges in Short-Crested Random Seas
Four large concrete floating bridges located in Washington State have been the subject of extensive analytical modeling for dynamic response to storm waves. The dynamic analysis of the...

Problems of Spectral Analysis in Dispersion Tests
The use of dispersive surface waves and spectral analysis methods is new to the nondestructive testing of airfield pavements. Such tests are to determine whether mechanical properties...

Diffraction Forces on Axisymmetric Bodies
Use of a Green function satisfying the governing differential equation and all boundary conditions except those on the boundary of the structure yields an integral equation, when these...

Effect of Seismic Wave Inclination on Structural Response
A new procedure is developed using the computer program SASSI to evaluate the effects of inclined propagating shear waves on three-dimensional seismic soil-structure interaction (SSI)...

A Stochastic Source Spectrum for Engineering Application
The solution of a point source (double couple) combined with K. Aki/A. S. Papageorgiou's stochastic source model is used to establish the power spectrum at the acceleration...

Design of Wharf Facilities, Guam, M.I., to Accommodate Difficult Site Conditions
A wharf facility currently under construction in Guam, Mariana Islands, for the U. S. Navy utilizes precast concrete box caisson construction to satisfy difficult site conditions. To reduce...

Perforated Wave Barriers in Small Boat Piers
Perforated breakwaters can be used to reduce the energy and the height of waves entering small boat harbors. By not extending the breakwater to the bottom interference with littoral drift...
