The Waterways Experiment Station is expanding the use of computer controlled data acquisition and control equipment on a variety of hydraulic models. These systems are presently being...
Development of a Practical Method Simulating Oil Spill Migration (OSPIM) in Soils
Many ground-water modeling studies can be performed on currently available microcomputers. The greatest problem associated with the proliferation of ground-water modeling software for...
Ground-water Modeling on Small Computers: Past, Present, and Future
The paper reports on research that concerns the possible development of numerical models being able to simulate practical cases of Oil Spill Migration (OSPIM) in soils. Such models can...
Role of Small Computers in Two-Dimensional Flow Modeling
This paper describes the computational aspects and computer usage history of numerical simulations of horizontal, free surface, steady or unsteady two-dimensional flow fields. The focus...
Automated Analysis of High Accident Locations
Identification of high accident locations and associated accident causative factors as well as determination and evaluation of appropriate remedial measures at these sites are continuing...
APM Configuration Concepts and Network Design
The simpler networks, along with several of the more complex variations, include the following: Single-Lane Shuttle, Single-Lane Shuttle with Bypass, Double-Lane Shuttle, Single-Lane Loop,...
Transport by Cable: Possibilities and Limits
Cable systems offer a high degree of passenger safety; they do not cause pollution and can, in a very flexible way, be adapted to the local conditions. They can be operated as reversible,...
Parametric Analysis of APM Operational Components: Stopping Policy, Stations and Headway
This study examines generically relationships among the three parameters using a single line transit system. Optimization models are developed to determine the optimum number of stops...
Dynamic Simulation of a DPM Auto Intercept System
This paper reports on the application of the UMTA Station Simulation Model (USS), which incorporates a dynamic path-choice algorithm, to model the diversion of motorists to a downtown...
The H-Bahn, a Fully Automatic People Mover System
The H-Bahn suspended cabin system is the contribution of the Siemens - DUEWAG joint development venture towards solving the problem of economical public transportation. This track-bound...
City of Pittsburgh Horizontal Elevator Experience: A Unique Application
The City of Pittsburgh is developing a unique and innovative application of horizontal elevator technology for use as downtown people-movers. The paper reviews the horizontal elevator...
Joint Flexibility in Steel Frames
This paper investigates the effects of connection flexibility and panel zone deformation on the behavior of plane steel frames. The incorporation of these factors in frame analysis will...
Flexibility of Steel Seismic Moment Connections
Relevant Berkeley experimental results are critically evaluated to determine the flexibility of W18 W24 beam joints with and without stiffeners and/or doubler plates. The paper discusses...
Shear Stresses in Composite Masonry Walls
The behavior of composite masonry walls subjected to inplane loads is a subject that has received little attention during the last few years. The small amount of experimental and analytical...
Can We Save the Ogallala?
The useful life of the Ogallala Aquifer, which underlies seven western states, can be extended indefinitely through water conservation in the widest sense of the term. In addition to optimization...
Danger: Natural System Modeled by Computer
Computer (mathematical) models are written to simulate such natural systems as those leading to acid rain, flooding, or toxic waste migration from disposal sites into groundwater. In some...
Computer Keeps New Orleans: Head Above Water
The city of New Orleans has been beset with drainage problems since its founding in 1718. A major drainage system was installed in the city in the late 1800s, but it has grown increasingly...
Simulating Construction Operations by Microcomputer
Field operations on major construction projects involve complex interactions among construction equipment, materials and supplies, skilled craft resources, and technical and administrative...
Modeling Construction Companies
This paper reports on the development, implementation, and practical use of a micro-computer based system which simulates the organizational performance of construction companies. The...
Avoiding Contractor Disputes During Project Design
The New Jersey Transit Corporation is in the second phase of a billion dollar rebuilding program of its rail system. The first phase, which featured electrification and signal system replacement,...
