A Perspective on Engineering Computing
Computing in engineering seems to be evolving very rapidly and yet the data shows that it frequently takes twenty years before a viable concept becomes widely available. Economics is the...
Problem Solving Using Expert System Techniques
There are basically two approaches to problem solving currently used in expert systems: the derivation approach and the formation approach. The derivation approach involves deriving a...
Expert Pattern Recognition for Pollution Source Identification
This paper presents an approach for developing an Expert System to aid the identification of locations and magnitudes of a finite number of groundwater pollution sources. A pattern recognition...
Computational Enhancements to a Multidimensional Dynamic Programming Algorithm
This paper discusses ongoing work in investigating the vectorization potential (speed-up) of multidimensional dynamic programming computer codes on the Control Data Corporation (CDC) CYBER...
Algorithms for Automatic Control of Diversion Dams
The application of local automatic control for the releases from a diversion dam that has intermittent river inflow is limited. For this case, it is better to install a remote monitoring...
Solving Nonlinear Equations on a Hypercube
Certain classes of nonlinear systems of equations, such as polynomial systems have properties that make them particularly amenable to solution on distributed computing systems. Some algorithms,...
Some Recent Advances in Automatic Mesh Generation
The establishment of automated finite element modeling procedures must begin with the development of automatic mesh generators capable of producing a valid finite element mesh for any...
A Mesh Generator for the Modeling of Rock Discontinuities
The need to characterize a rock mass by collecting field data is receiving more and more emphasis as larger, more ambitious underground structures are being built. Yet there is a need...
Knowledge Bases for Multistory Concrete Buildings
Heuristics are used in the concrete building industry. A knowledge base is developed with heuristics used in the selection of the floor framing system of a concrete building....
Frame Moments with the Takabeya Method
The Takabeya method of frame analysis, based on the same slope-deflection equations as the Hardy-Cross system, has the advantage of requiring much less memory and fewer computations than...
Optimization of Looped Water Distribution Networks
The optimization algorithm developed by G. Quindry et al. can be used to obtain a least cost pipe network for a looped water distribution system. A solution is obtained under steady state...
OPNET: A Nonlinear Design Algorithm for Hydraulic Networks
The author has developed a general computer program OPNET to be used in the optimal design of hydraulic networks. The computer program can be used to optimize three basic variables; tank...
Multi-Objective Planning: Great Lakes Water Policy Issues
This paper reports upon the development of computer algorithms for multi-objective planning for Great Lakes water policy issues. Sample applications are presented for the control of phosphorus...
Setup and Usage of Multitasking Microcomputers for Water Management Problem Solving
Software and hardware that were developed in the evolution of the microcomputer from the Altair to today's state of the art multitasking systems are discussed. The rationale...
Relating Water Treatment Problems to O & M Factors
The author discusses the operations and maintenance factors that must be considered in dealing with water treatment problems....
Microcomputer Methods for Toxicants in Ground Waters and Rivers
This paper describes a program written for the IBM personal computers to assess the fate of toxicants in ground waters and in rivers. The algorithms in the program were selected from a...
Problems in Design of Small Reverse Osmosis Water Purification Systems
Small reverse osmosis water purification systems may be defined as those systems which produce from 100 to 20,000 gallons of water per day. This paper identifies some of the common problem...
Computation of Gradually-Varied Flows in Channel Networks
For computing steady-state, gradually-varied flows, a new algorithm is presented which allows solution of the entire channel system simultaneously, and unlike other available methods,...
Resource Allocation with Project Manager Control
There are some logical reasons behind the partial acceptance of the resource allocation research by the construction industry. These reasons are based on field experience and the daily...
