Monitoring Techniques for Thermosyphons
Two-phase thermosyphons used for passive soil refrigeration are monitored using a variety of techniques ranging from visual infrared scanning to measurement of internal pressures. Methods...

Design Evaluations in Support of Offshore Facilities and Gravel Islands in the Arctic
Development of oil resources in Northern Alaska has involved the design of nearshore and offshore facilities and structures in the Beaufort Sea and Prudhoe Bay in water depths ranging...

Alyeska Reroutes Trans-Alaska Pipeline at MP 200
This paper discusses the 1985 wintertime repair/reroute to the Trans Alaska Pipeline System (TAPS). The rerouted pipe was approximately 4000 feet long and cost approximately 27 million....

Performance Study of the Lagoon at Inuvik, N.W.T.
Since 1957, Inuvik's sewage has been discharged into a lagoon situated northwest of the townsite. In 1982 the lagoon was upgraded to a two-stage system. Two primary cells...

Finite Element Modelling of Cold Regions Concreting
Finite element heat transfer computer programs are discussed in regard to their use in modelling cold weather concreting. The concrete material properties required for input to the finite...

The Effect of Water Supply and Sanitation Systems on Disease Patterns on Manitoba Indian Reserves
This study examines the links between water supply and sanitation and health on Indian reserves in Manitoba. Health data on water related diseases were obtained from health care agencies....

Coal Mining in Alaska's Interior: Problems and Solutions
The Usibelli Coal Mine located in Healy, Alaska is currently the largest operating coal mine in the state of Alaska. The mine has recently increased production to nearly 1. 7 million tons...

Legal Concerns in Cold Regions Engineering and Construction
For a variety of reasons the potential for the imposition of liability and the potential for comparatively large damage claims is greater in cold regions. It is the purpose of this paper...

Expert Systems and Engineering Design Knowledge
As in many current AI (Artificial Intelligence) systems, knowledge processing is the most important issue in expert systems. 'Knowledge' in engineering applications...

Applications of Artificial Intelligence in Preliminary Structural Design
The field of Artificial Intelligence (AI) deals with the problems of modeling human intelligence. The application of AI to structural engineering has been limited, but potential applications...

Broke2: A Program for Broken Wire Analysis
A computer program to study the dynamic behavior of an electric transmission line system when wires suddenly break has been developed by the authors. All three of the line elements: the...

Microcomputer Program for Bridge Analysis & Rating
The microcomputer software system, BRCOM, for the analysis and rating of bridge superstructures is described. The system consists of ten programs written in UCSD P-System FORTRAN, which...

Interactive Analysis and Design Program for Girder Bridges
An interactive microcomputer program for the analysis, design, and rating of girder bridges is presented. The program, GBRIDGE, is user-friendly, menu-driven, and developed in modular...

A Microcomputer CAD System for Seismic Design of Regular Highway Bridges
A microcomputer program to implement the recent seismic design guidelines for highway bridges is described. The methodology was developed by the Applied Technology Council (ATC) and is...

Solving Finite Element Structural Dynamic Problems on Small Computers Using Semi-Explicit Methods
Numerical techniques based on the partial decomposition of a coefficient matrix, are developed for structural dynamic problems. Improved iterative techniques are discussed which could...

Measuring Dynamic Occupant Loads by Microcomputer
Present building codes regard live loads caused by human movement as deterministic; values are based upon experience and tests run in 1912, 1922, and 1932. An experimental project to statistically...

Managing Software for More Efficient Design
Efficient design of structural members with microcomputers requires a large variety of analysis, design, and check programs. The management of these programs can best be accomplished with...

Symbols for Controlling CAD Software
The use of graphic symbols for controlling complex CAD software is discussed. Emphasis is put on the advantages of icons over text. Guidelines for developing and adapting graphic symbols...

Conversion of WECAN to a Minicomputer Environment
The increasing use of Virtual Memory Systems (VMS) and their incorporation in a range of computers from large mainframe to micros indicates the desirability of converting WECAN to run...

Interactive Design of Reinforced Concrete Foundations
A new, highly graphical foundation design program, FOUNDATION-3D, provides the designer with a variety of easy to use foundation design tools in a flexible interactive environment. It...
