Emplacement Drift Temperature Reduction by Cooling Enhancement and Ventilation
The application of cooling enhancement in a short vertical container emplacement layout is analyzed. Two 25 m-long heat pipes upward oriented at 45 degrees are installed at each emplacement...

Boston's Sewage Outfall
The centerpiece of the Boston Harbor cleanup plan will be the sewage plant on Deer Island, which will treat water from 43 municipalities in the Boston metro area�500 mgd to start. In order...

Infrared Thermography Based Pipeline Leak Detection
Computerized Infrared Thermographic pipeline inspection is now a refined and reliable process having been thoroughly proven to be an accurate, cost effective, and efficient technology...

Design Program for Gravity Sanitary Sewers
The Gravity Sewer Design Program Version 2.1 M (GSDP2M) performs the hydraulic design for a conventional gravity sanitary sewer network. GSDP2M is written in standard Fortran 77 for batch...

Application of GIS in Monitoring and Trouble Shooting of Water Distribution Systems
In this study, the suitability of Geographical Information System (GIS) to monitor water distribution systems is investigated. Although GIS applications are widespread, the use of GIS...

Diagnostic Options for Pipeline Rehabilitation
The various diagnostic options utilized for solving pipeline problems/failures continue to increase at a very rapid pace. Field reconnaisance and/or man-entry of pipelines is becoming...

The Danby Pipe Renovation System
This paper describes a pipe renovation system and its structural characteristics which is cost effective and technically suitable in all sizes of pipe from 8 inches (200 mm) to the largest...

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...

Network Modeling in a Water System with Ferrous Deposits
This paper presents the experiences and results of a network modeling study. A model for the University of Idaho water supply system was developed and verified to the extent possible with...

A Comprehensive Algorithm for Network Calibration
An explicit calibration algorithm is proposed which provides the direct and rapid adjustment of the pipe roughness coefficients and junction node demands that exactly meet a specified...

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...

Block-based Solvers for Engineering Applications
This paper compares the performance of standard linear system solvers, LINPACK, widely used in engineering applications, and PARALIN (a block-based package for linear systems) on the Alliant...

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...

On the Design of Laminated Composite Flange: A Model with Experimental Verification
A parametric model has been developed for the optimum design of laminated composite flange. The study focuses on the evaluation and performance optimization of composite flanges with the...

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'...

Pipeline Crossings
This proceedings of the Pipeline Crossings Conference, held on March 25-27, 1991 in Denver, Colorado, presents information on aspects of various pipeline crossings. It covers such broad...

Cables Not in Trouble
Cable-stayed bridges in the U.S. are not, contrary to reports widely disseminated in the press several years ago, about to fail from corrosion. The design, in which primary cables support...
