A Methodology for the Development of a Production Experience Database for Earthmoving Operations Using Automated Data Collection
(Virginia Tech, 1999-05-26)
Automated data acquisition has revolutionized the reliability of product design in recent years. A noteworthy example is the improvement in the design of aircrafts through field data. This research proposes a similar ...
Integrated Model to Plan Advanced Public Transportation Systems
(Virginia Tech, 1998-08-11)
The primary objective of this study is to develop an integrated public transportation planning framework to evaluate and plan Advanced Public Transportation Systems (APTS). With this purpose, a systems approach point of ...
Using Simulation to Quantify the Impacts of Changes In Construction Work
(Virginia Tech, 1998-08-18)
Work changes are alterations to the original scope of a contract. Work changes are inevitable in a typical construction project due to the complex nature of the construction industry. It is not possible to foresee these ...
Analysis of Freeway Weaving Areas Using Corridor Simulator and Highway Capacity Manual
(Virginia Tech, 1997-12-01)
Weaving is defined as the crossing of two or more traffic streams traveling in the same direction along a significant length of the highway without the aid of traffic control devices . The traditional methods used for ...
Enabling 3D Visualization of Simulated Construction Operations
(Virginia Tech, 2000-10-19)
Simulation modeling and visualization can substantially help in designing complex
construction operations and in making optimal decisions where traditional methods prove
ineffective or are unfeasible. However, there has ...
Finite Element Analysis of Single Plate Shear Connections
(Virginia Tech, 2004-05-05)
There have been several design models for single plate shear connections in the past 20 years. The current design model states that the bolt shear rupture strength of a connection is a function of the number of bolts and ...
Simulation of High-velocity Penetration for Rigid Projectile into Plain Concrete Target using Discrete Element Method
(Virginia Tech, 2009-02-04)
Penetration of high velocity is of concern for both civilian and military research for decades, and computerized simulation is the scholarâ s focus in recent years. This study presents a study on the Discrete Element ...
System Dynamics Model for Testing and Evaluating Automatic Headway Control Models for Trucks Operating on Rural Highways
(Virginia Tech, 1996-04-01)
The objective of this research is to explore a methodology that can be used for testing and evaluating AVCS technologies, and, in particular, automatic headway control models for trucks operating on rural highways. The ...
Strategic valve locations in a water distribution system
(Virginia Tech, 2005-05-06)
Valves play a critical role in a water distribution system for subsystem isolation and flow or pressure control. Among them, subsystem isolation is required to repair or to rehabilitate a broken component and can be done ...
Integrated Modeling of Air Traffic, Aviation Weather, and Communication Systems
(Virginia Tech, 2007-04-20)
Aviation suffers many delays due to the lack of timely air traffic flow management. These delays are also caused by the uncertainty weather information; and the lack of efficient dissemination of weather products to pilots. ...
