Pattern Recognition Techniques for Distinguishing Structural Failure Modes from High Pressure Loading Records
Pattern recognition techniques have been successfully employed in a wide variety of fields, such as geophysical exploration, medical diagnosis, radar tracking, and earthquake structural...
Computer Errors?Who's Responsible
This paper proposes that both the program developer and the program user share the responsibility for preventing errors in the use of computer programs for engineering design and analysis....
Planning Computer Development to Increase Productivity
The use of computers and computer programs has become widespread in the engineering industry. Various types and classes of hardware are available with software for varied purposes. Certainly...
Construction Resource Analysis Using Symphony
In 1983, the Air Force was directed to commence engineering design of a small, single warhead ICBM for potential deployent in the early 1990's. As construction agent for the...
Computerized Construction Progress Control
In 1983 and 1984, an exploratory tunnel was constructed as part of the geotechnical exploration program for two highway tunnels to be constructed for interstate 70 through Glenwood Canyon,...
Advanced Microcomputer Simulation for Construction Managers
The concept of simulation allows the analysis of complex and dynamic systems such as those encountered in construction operations. In particular, the technology orientation of construction...
A Method for Computerized Site Characterization
Site characterization, the process of evaluating subsurface soil, rock, and groundwater conditions and their impact on project design and construction is a common element in every major...
Personal Computer Environment for Minicomputer Users
Users find that personal computers can perform most functions previously available only on minicomputers or even mainframe computers. Companies have an imbedded investment in existing...
Selection of Computer System
To buy a system is a major decision undertaken by the user. It has major impact on the financial and the manpower aspect of the company. To enable the user to arrive at a rational decision,...
Finite Element Analysis of Structural Details in Large Steel Bridge Superstructures
Various approaches for the finite element modeling of the connection details in large steel bridge superstructures are presented. It is noted that an accurate analysis of these details...
Groundwater Modeling: Selection of Computing Systems
Results are presented for ten microcomputer systems evaluated with respect to system performance in solving a test case three-dimensional groundwater flow problem. The model used was the...
Facing Failures: Alleged or Actual
Every practitioner, in a large or small office, faces the possibility of an accusation of causing, directly or indirectly, a failure. The resulting embarrassment, frustration, regret,...
Failures: Who Did It - How Did It Happen?
The forensic engineer investigates the cause of failures and determines, from an engineering viewpoint, who was responsible for that failure. These failures need not be catastrophic but...
How Do I Find the Information I Needed Yesterday?
One reason that the professional has not been more effective in learning from failures is that the information disseminated has not always reached the right people. The Architecture and...
Avoiding Failures Caused by Lack of Management
Engineering failure often results from administrative or managerial failure. In addition to providing sound engineering or technical services, we have a responsibility to administer and...
Computer Use in Structural Analysis
Acquisition of computer hardware and software in order to establish distributed processing and a local area network at the Air Force Weapons Lab has greatly streamlined two structural...
Sources of Urban Pollutants?Do we Know Enough?
The non-USGS data from the NURP program are summarized in terms of their availability and adequacy for decision making and modeling. Results of selected projects are reviewed and related...
Estimation of Urban Storm-Runoff Loads
The United States was divided into three regions, on the basis of mean annual rainfall, to decrease the variability in storm-runoff constituent loads and to improve regression relations...
Effectiveness of Erosion Control
Erosion control in the urban environment is addressed from the perspective of the mechanisms of erosion. The primary cause of erosion in urban areas is flowing water. Measures are identified...
Lognormality of Point and Non-Point Source Pollutant Concentrations
This paper presents a series of probability plots of water quality data from a variety of discharge sources. It is intended to provide a visual display of the appropriateness of characterizing...
