Queue Management has been a problem for many years in many domains including the Financial, Health Care, Public and Retail Sectors. In this age of technology it is not only important to organize the existing queue, but to ...
A Meta-Parallel Evolutionary System for Solving Optimization Problems
(2007-05-15)
The purpose of the Meta-Parallel Evolutionary System (MPES) is to develop fast,
efficient parallel evolutionary systems for function optimization. Given an optimization
problem and a set number of nodes available for the ...
Voice Interactive System: A Usability Study of the Voice Survey Creator
(2007-05-15)
The voice user interface survey is aimed at providing an easier and more efficient way of creating surveys that is conducive to the entire population. This system allows a person to call and create a survey solely over ...
Evaluation of Load Tests for Driven Piles for the Alabama Department of Transportation
(2007-05-15)
A study was carried out to evaluate load testing methods for driven piles for the Alabama Department of Transportation. Dynamic and static load test data were assembled to form the database used in this study. The field ...
Bond Behavior of Prestressed Reinforcement in Beams Constructed with Self-Consolidating Concrete
(2007-05-15)
Accurate behavioral characteristics of self-consolidating concrete (SCC) should be
established prior to its widespread implementation in prestressed members. This thesis
describes an investigation of bond behavior of ...
Integration of GIS into Pavement Management Systems for Low Volume County Roads
(2007-05-15)
Geographic Information Systems (GIS) have often been used for highway pavement management (PM), but rarely for low volume county roadway systems. Methods for implementing GIS as a useful tool for county engineers in ...
Early-age cracking of mass concrete structures
(2007-05-15)
Early-age cracking is a recurring problem in many mass concrete structures. Currently agencies tend only to limit the maximum temperature difference that may develop in a mass concrete structure in an attempt to mitigate ...
Finite-Element Modeling of a Damaged Prestressed Concrete Bridge
(2007-05-15)
Spans 10 and 11 of the Interstate Highway 565 bridge structure in Huntsville, Alabama were noticed to be cracked shortly after their construction. Alabama Department of Transportation (ALDOT) employees investigated and ...
Investigation of Permeable Asphalt Treated Bases in Alabama
(2007-05-15)
The Alabama Department of Transportation currently uses a permeable asphalt treated base (PATB) course layer consisting of an AASHTO number 57 aggregate gradation with 2.0% to 2.5% asphalt content. The current mixture ...
Fate, Transport, and Environmental Availability of Cu(II) Applied in Catfish Aquaculture Ponds and Enhanced Immobilization of Soil-bound Lead Using a New Class of Stabilized Iron Phosphate Nanoparticles
(2007-05-15)
Copper sulfate has been the most commonly used algaecide for about a century in the U.S. to control the off-flavor problem caused by blue-green algae in channel catfish (Ictalurus punctatus) ponds. In 2001, the ~80,000 ...
An Evaluation of the Alabama Service and Assistance Patrol with Respect to Mobility-Related Benefits
(2007-05-15)
