(2011-05-13)
The following thesis provides a detailed description of the design and development of magneto-resistive unexploded ordinance (UXO) sensor array to detect the perturbations in the Earth’s magnetic field due to the presence ...
Measuring the Effects of Bridge Deck Replacement Methods on Construction Performance Factors
(2011-05-11)
The objective of this research was to develop and evaluate a methodology for measuring the effect of various bridge deck replacement methods on the total cost, schedule, and road user costs of a bridge project. Steps are ...
Transfer Length in Bulb-Tee Girders Constructed with Self-Consolidating Concrete
(2011-05-11)
This thesis is focused on the transfer bond behavior of self-consolidating concrete (SCC) relative to conventionally vibrated concrete (CVC) in full-scale, plant-cast, prestressed concrete bulb-tee girders for implementation ...
Process Control Factors for Continuous Microbial Perchlorate Reduction in the Presence of Zero-Valent Iron
(2011-05-11)
Water is a staple of civilization, and in the event of drinking water contamination the use of the contaminant’s source should be discontinued. Alternatively, a technology that can remove the contaminant from the water ...
Hot Water Extraction and Subsequent Kraft Pulping of Pine Wood Chips
(2011-05-10)
This research investigated the effects of pre-extraction time, temperature, and pH on the rate and quantity of sugars recovered from Loblolly pine wood chips and the impact this treatment has on pulp kappa number and yield. ...
Wall Following Algorithm for a Mobile Robot Using Extended Kalman Filter
(2011-05-10)
This thesis proposes a wall-following algorithm for mobile robots using the Extended Kalman Filter. The robot navigates in a known environment where the baseboard of the wall is used as a natural landmark and indentified ...
