Momentum and Kinetic Energy Coefficient Research?Ramp Flumes
In October 1984. Reclamation Hydraulic Branch staff members investigated the operation of the A-Canal ramp at Klamath Falls, Oregon. The ramp flume was completed in 1983 as a water measurement...
Decoverly Lake?Functional Hydraulics & Aesthetics
The Decoverly Office Park is located in Rockville, MD. In 1984, engineering design on the seven office building park and pond was begun by the consulting engineers. From the beginning,...
Experiences With a Supercomputer
The advent of ever faster and ever larger computers is opening new areas of scientific study. Within this computational revolution, however, are real people trying to cope with the vagaries...
A Tale of Two Laboratories
Two unusual research centers are built with the materials that will be studied in them, but the similarities end there. GE Plastics' $10 million Living Environments concept...
Overview: Steam-Water Phase Change in OTEC Systems
This paper presents an overview of the thermodynamics and the heat and mass transfer processes occurring in OTEC systems utilizing seawater as the working fluid....
Optimum Removal of Noncondensable Gases for Open Cycle OTEC System
For an open cycle OTEC system the dissolved gases in warm surface seawater are evolved in the flash evaporator. Those behave as noncondensable gases in the condenser and degrade the condensing...
Experimental Investigation of Condensation of Steam in the Presence of Noncondensable Gases for Open-Cycle Surface Condensers
Two experimental investigations are being carried out for determination of the effects of noncondensable gases on the rate of condensation in the open-cycle surface condenser. A single-channel...
Wood Variability Effects in Structural Assessment
Engineers evaluating the load carrying capacities of in-service wood structures commonly determine the strength and stiffness properties of structural wood members by various assessment...
Protection of Wood Designs in Adverse Environments
Engineers and architects are becoming increasingly aware of the risks of poor wood design practices and the benefits of using wood properly. This paper addresses biological factors that...
Long-Term Performance Reliability of Wood Materials
The United States faces a major task in maintaining and rebuilding the nation's infrastructure in the 1990's and beyond. Economic constraints have limited funds...
Repair of an Improperly Detailed Masonry Facade: A Case History
The masonry facade of an 18-story condominium building was constructed with an inconsistent pattern of shelf angle supports, marginal lateral restraints and without any horizontal control...
Building Joint Movement
Moisture leakage in masonry claddings occurs not only through copings and facial separation cracks, but also through failed sealant joints in the veneer. The factors affecting joint movement...
Three Tools for Design Test Bed Analysis
Three analytical tools are outlined for use in design test bed work focusing on the design/production interface. The tools are substitution analysis, coupling analysis, and value chain...
AE Instrumentation and Deconvolution Techniques
This paper describes the difficulties and solutions achieved in applying advanced Acoustic Emission (AE) signal analysis techniques to fracture mechanics. The test specimen is a double...
Application of Waterjet Cutting for Pothole Repair
A study was conducted to determine the feasibility of utilizing high pressure waterjet cutting technology as an infrastructure maintenance tool. The influence of waterjet cutting parameters,...
Theoretical Prediction of Temperature Distributions in Airfield Runway Pavements Due to Aircraft Operation
The determination of this transient temperature distribution is important in predicting the thermal effects on pavements due to aircraft operation. In this research, heat exchange at the...
More Than a Public Hearing
Too often, required community input is reduced to the sometimes dreaded public hearing. Many formal public-involvement programs are comprised of no more than this minimal, yet essential,...
Prospects for International Engineering Practice
International trade is growing in construction products and services. It is stimulated by international efforts to reduce technical barriers to trade and the formation of a single European...
