Random Vortex Models in Wind Engineering
Random vortex methods are Lagrangian particle-based numerical simulation schemes especially appropriate for Wind Engineering simulations. Vortex methods do not suffer from numerical diffusion...
Case Storage of Planning Knowledge for Power Plant Construction
Schedulers consider a variety of constraints when they analyze a project to schedule the construction work for it. Often they will start from some schedule that they recall from a previous...
Microworlds for Learning Through Inquiry
We discuss several computer-based environments to support learning through inquiry, called microworlds, including two focused on steam power plant operation and electronic troubleshooting....
Empirical Performance Comparison for Symbolic and Subsymbolic Learning Systems
The paper gives a description of a comparative study of two learning systems based on symbolic and subsymbolic learning. The two systems' performance was analyzed using the overall empirical...
An Interactive Computer Code for Generations of Artificial Earthquake Records
A new interactive computer code is presented in this work for the calculation of artificial earthquake records that comply with any arbitrarily specified target response spectra or power...
A Knowledge-Based Computer System for Financial Wind Risk Management
This paper presents the results of a sponsored applied research project conducted by a multi-disciplinary team to integrate state-of-the-art methods in wind and collateral (e.g., surge,...
Rate of Settlement of Silt Alluvium at Trojan
Settlements of 1.83 m have been observed at the switchyard of the Trojan Nuclear Power Plant over a 22-year period since 1970. Rockfill had been placed on the site, a flood plain of the...
Strain Measurement on the Runner of a Hydroelectric Turbine
Twelve strain gages were installed on the 10-m-diameter runner of Unit G-23 (700 MW) at Grand Coulee Dam, Third Powerhouse. The gages were located on both the pressure and suction sides...
Testing Turbine Aeration for Dissolved Oxygen Enhancement
During August of 1993 the Bureau of Reclamation tested turbine aeration for dissolved oxygen (DO) enhancement at Deer Creek Powerplant near Provo, Utah. This test required a variety of...
Pressure-Time Flow Rate in Low Head Hydro Plants
Very few methods are accepted for measuring the flow in the large intakes typical of low head, run-of-the-river hydro plants. These intakes are characteristically short, non-uniform, non-prismatic,...
A Computer-Controlled, Precision Pressure Standard
The operating principles as well as the technical aspects of the implementation of a precision pressure standard are presented here. The instrument can have dual use: either as a pressure...
On the Erodibility of Rock and Other Earth Materials
An outline of a new method to determine the erodibility of rock and other earth and engineered earth material is presented. The method quantifies the relative capacity of the boundary...
Scada System Requirements for Optimum Pumping
In order to minimize the cost of electric energy for pumping water through its distribution system, a computer program was developed to schedule the operation at eight pumping stations...
Integrated Planning for International River Basin
The integrated development of the Vardar/Axios Basin includes a system of projects scheduled to meet the needs and aspirations of Yugoslavia (in particular, the former Socialist Republic...
Spectral and Parametric Wave Models of Lake Erie
The GLERL-Donelan parametric wave model and the SHALWV spectral wave model are presently being used as modules of the Great Lakes Forecasting System in order to determine which best fits...
Fish Entrainment and Strategies for Diversion
Hydroelectric power projects often impound reservoirs which contain important recreational fisheries. The entrainment of fish through these facilities and the possible associated entrainment...
Hydro Plant Research Data Acquisition System
The Colton Hydroelectric Development, located on the Raquette River in the northwestern part of New York State, is the site of a two year research project to test the use of heated trashracks...
Floodflow Effects on Riparian Vegetation in Arizona
A relation for estimating changes in the condition of riparian vegetation as a function of stream power was developed for stream channels in central Arizona. Flood and vegetation data...
Numerical Model Verification on Tidal Current in Tokyo Bay
Results of a research project to verify the Multiple Level Model for a tidal current analysis in Tokyo Bay are presented in this paper. This study is a part of the subject for the Task...
Estimation of Design Surge Heights by Utilizing Meteorologic and Oceanographic Data
Data on cyclonic storm surge height have been generated with the help of a statistical simulation model. Data on observed maximum cyclonic wind speed and the length of the continental...
