Numerical Accuracies in Steady Open Channel Flow
The authors have reviewed the accuracy of the individual terms and formulations of the conservation of energy equation as used within the constraints of steady open channel flow modelling....
A Study on Estimation of Aquifer Parameters in Unsteady Seepage Flow
A method which automatically identifies aquifer parameters is proposed in this paper. The aim of this investigations is to estimate transmissivities and storage coefficients of unsteady...
Estimation of Wave Power as an Energy Resource for Hawaii
One of the most important elements in determining the wave power available by means of a wave power extracting device is the amount of wave energy present at a given location during a...
A Comparison of Straight and Circular Fibers for Concrete
Two previous studies of concrete reinforced with closed loop fibers are reviewed. Statistical moments of fiber systems are derived, including the expected values of the fiber embedment...
Impact of Errors on Safety During Construction
The construction process involves a number of procedures which integrate together from the first intention of building the project to the end of the structural cycle. In this study, a...
Modal Parameter Identification of an Offshore Platform from Earthquake Response Records
The Whittier Narrows earthquake on October 1, 1987, was recorded by the earthquake monitoring system on an offshore platform installed in a water depth of 97 m in the Santa Barbara Channel....
Screw Plate Test for Drained and Undrained Soil Parameters
This paper describes a screw plate test device developed with a capability to measure the generation and dissipation of excess pore water pressure during testing in cohesive soils. The...
A Use of Geostatistics to Predict the Occurrence of Collapsing Soils
Collapse susceptible soils are those that are stable under load while they are dry, but undergo large decreases in volume virtually instantaneously, when they become wetted to near saturation...
Statistical Analyses of Drilled Shaft and Embedded Pole Models
In recent years a significant effort has been made by the Electric Power Research Institute (EPRI) to develop new design models, to collect and summarize existing load test data and to...
In Situ Determinations of Dispersion and Transport Parameters at Piraquara De Fora (RJ)?Brazil, With Help of a Fluorescent Dye Tracer
This paper deals with 'in situ' determinations of the transport and dispersion parameters at Piraquara de Fora cove, near the site where the first Brazilian nuclear...
Geocosta Operations?A Program of Oceanographic Expeditions for the Brazilian Inner Shelf
In July 1979, a new expedition was conducted with the R.V. Almirate Camara, in the same area as GEOMAR X, with the following purposes: surveying profiles with side scan sonar and conducting...
Convection in the Classroom
By their nature, the empirical relations used to calculate convective heat transfer coefficients offer the user little or no insight into how the typical input parameters, e.g., pipe diameter...
Adaptation of ANSI Standards for Communications Testing in the Connectionless Environment
American National Standards (X 3.102 and X 3.141) establish a uniform means for specifying, assessing and comparing performance of data communications systems and services from the point...
Local Area Network Communications Testing
This paper presents the philosophy developed for benchmark communications testing in networks typical of CAD/CAM environments. Implementation of the test philosophy in a connectionless...
Performance Testing of Wide Area Networks
Institute for Telecommunication Sciences (ITS) has developed a software measurement system to support the ANSI standards X3.102 and X3.141. This system is being used to evaluate data communication...
Conducting a Waterline Corrosion Evaluation
A study has been conducted to determine the level of corrosion activity occuring on the U.S. Navy's potable waterlines on Guam. The study evaluated soil parameters including...
Pre-Formed Aluminum Hydroxide as an Alternative to Alum for Coagulation
The objective of this research was to conduct a comparison study of the coagulants, alum and pre-formed aluminum hydroxide, for turbidity and color removals in water treatment. By examining...
Experimental Study of Windrow Composting of Sludge
An experimental field study of the windrow composition of sludge at the City of Dallas, Texas, Southside Waste Water Treatment Plant was conducted to provide data for possible design of...
Low-Level Waste Disposal Design: An Overview
Low-Level radioactive waste disposal is regulated by several agencies. Mixed waste, which is both radioactive and chemically hazardous is regulated by two agencies with potentially different...
Cokriging for Evaluating Agricultural Pollution
Subsurface drainage data from irrigated lands near Twin Falls, Idaho were used. Total Dissolved Solids and NO3-N were selected as variables. The...
