An Automated Database System for Construction Bidding
A number of probability-based bidding models have been developed to assist a contractor in preparing bids that improve chances of winning over the competition. Models based on utility...
Qualitative Formulation of Load Paths Through a Functional Description of Structures
The past few decades have seen major advances in computer tools to analyze complex structures and loadings. For the most part, these programs have focused on two areas - A, programs for...
Crack and Contact Problems in Masonry Arch Bridges
A two-dimensional finite element program has been developed to predict the load carrying capacity of masonry arch bridges with different structural defects such as missing bricks and tangential...
Analysis of Sequential Route Choice Under ATIS
An experiment to collect sequential route choice data under the influence of an Advanced Traveller Information System (ATIS) was performed using a PC-based interactive simulation. The...
User-Friendly Simulation Model for Traffic Networks with ATIS/ATMS
Implementation of ATIS (Advanced Traffic Information Systems) and/or ATMS (Advanced Traffic Management Systems) are proceeding in many cities around the world, but only very few frameworks...
The DWR Delta Graphical User Interface
Previously, most modeling development has been in the area of algorithms, with relatively little effort spent on conveying the results of models. A graphical user interface to a database...
Reliability-Based Assessment of Navigation Structures
In 1989, the Director of Civil Works, U.S. Army Corps of Engineers (HQUSACE), requested regional assessments of the future modernization needs of Corps Divisions with significant inland...
Design and Construction Support with Object-Oriented Database Kernel Systems
