Mechanical and optical behavior of a novel optical fiber crack sensor and an interferometric strain sensor
(Massachusetts Institute of Technology, 2002)
The proper interpretation of measurements from an optical fiber sensor requires a full understanding of its mechanical response to external action and the corresponding change in optical output. To quantify the mechanical ...
Integrating driving behavior modeling
(Massachusetts Institute of Technology, 2003)
A framework for integrated driving behavior modeling, based on the concepts of short-term goal and short-term plan is proposed. Drivers are assumed to conceive and perform short-term plans in order to accomplish short-term ...
Development of technical bases for using infrared thermography for nondestructive evaluation of fiber reinforced polymer composites bonded to concrete
(Massachusetts Institute of Technology, 2002)
Fiber-reinforced polymer (FRP) composites, in the form of pultruded laminates or built-up woven fabrics, are being used widely to strengthen existing concrete and masonry structures. The success of these materials in ...
Fundamental analysis and conceptual model for corporate strategy in global engineering and construction markets
(Massachusetts Institute of Technology, 2002)
Strategic management as an academic field of study has spanned over four decades. As an interdisciplinary subject that enjoys concurrent contributions by allied disciplines such as economics and social science, numerous ...
An adaptive domain-independent agents-based tutor for Web-based supplemental learning environments
(Massachusetts Institute of Technology, 2003)
The Physics Interactive Video Tutor (PIVoT) is a Web-based multimedia resource for college-level Newtonian mechanics. The Personal Tutor (PT) is an intelligent tutoring system (ITS) integrated into PIVoT, assisting students ...
Chemomechanics of calcium leaching of cement-based materials at different scales : the role of CH-dissolution and C-S-H degradation on strength and durability performance of materials and structures
(Massachusetts Institute of Technology, 2003)
Calcium leaching is a durability threat for cement-based materials employed in critical infrastructures, such as Nuclear Waste Storage Systems. This thesis presents a comprehensive study of the material and structural ...
Stochastic analysis of dense nonaqueous phase liquid dissolution in naturally heterogeneous subsurface systems
(Massachusetts Institute of Technology, 2003)
Field-scale Dense Nonaqueous Phase Liquid (DNAPL) dissolution in three-dimensional heterogeneous subsurface systems is investigated using a stochastic approach that treats the variability of flow properties as three-dimensional ...
Experimental and theoretical modeling of DNAPL transport in vertical fractured media
(Massachusetts Institute of Technology, 2003)
In recent years, groundwater contamination by dense, non-aqueous phase liquids (DNAPLs) such as chlorinated solvents and polychlorinated biphenyls (PCBs) has become an important environmental concern in many industrialized ...
Copper speciation in estuaries and coastal waters
(Massachusetts Institute of Technology, 2002)
The goals of this dissertation are to better understand the sources and the Cu binding ability of ligands that control Cu toxicity in estuaries and harbors, where elevated Cu concentrations have caused documented toxic ...
Polyethylene devices and the effects of sediment resuspension on the cycling of PAHs and PCBs in the lower Hudson Estuary
(Massachusetts Institute of Technology, 2003)
In order to examine the importance of sediment resuspension on the sediment bed-to-water column transport of hydrophobic organic contaminants (HOCs) in the lower Hudson Estuary, the following areas of research were pursued: ...
