Interdigital dielectrometry sensor design and parameter estimation algorithms for non-destructive materials evaluation
(Massachusetts Institute of Technology, 1999)
The major objective of this thesis is to develop instrumentation and parameter estimation algorithms for nondestructive measurement of non-homogeneous material property profiles with fringing electric field dielectrometry ...
Unequal development : decentralization and fiscal disparities in the Metropolitan Zone of the Valley of Mexico
(Massachusetts Institute of Technology, 2006)
This study is about the impact of decentralization in metropolitan areas. Studies of fiscal decentralization have largely centered on the formal tiers of government, without looking at the effects of this process on the ...
Modeling the effects of systematic process variation of circuit performance
(Massachusetts Institute of Technology, 2001)
Relative Hilbert scheme methods in pseudoholomorphic geometry
(Massachusetts Institute of Technology, 2004)
This thesis takes up a program initiated by S. Donaldson and I. Smith aimed at using symplectic Lefschetz fibration techniques to obtain information about pseudoholomorphic curves in symplectic 4-manifolds. Donaldson and ...
Facility location and the analysis of algorithms through factor-revealing programs
(Massachusetts Institute of Technology, 2004)
In the metric uncapacitated facility location problem (UFLP), we are given a set of clients, a set of facilities, an opening cost for each facility, and a connection cost between each client and each facility satisfying ...
Roles of grain boundaries in cleavage cracking and thermal crack arrest experiments in iron-silicon alloy
(Massachusetts Institute of Technology, 2002)
High-angle grain boundaries in steel offer an important resistance to the propagation of cleavage cracks that affects the fracture toughness and can modulate the ductile-to-brittle transition temperature of fracture downward. ...
Finite element analysis of shells with layers
(Massachusetts Institute of Technology, 2002)
It is well established that thin shell structures frequently feature narrow bands of strain concentration and localized displacement irregularities referred to as boundary and internal layers. It is crucial to capture these ...
Empirical essays on finance and development
(Massachusetts Institute of Technology, 2009)
The central focus of this dissertation is the role of financial instruments, in particular insurance and credit, in economic development. Motivated by the observation that exposure to the risk of extreme weather conditions ...
Modeling the active sites of non-heme diiron metalloproteins with sterically hindered carboxylates and syn N-Donor ligands
(Massachusetts Institute of Technology, 2009)
Chapter 1. Different Synthetic Approaches to Modeling the Active Sites of Carboxylate-Bridged Non-Heme Diiron Enzymes Carboxylate-bridged non-heme diiron enzymes activate dioxygen to perform a variety of biological functions. ...
Out of control? : local democracy failure and fiscal control boards
(Massachusetts Institute of Technology, 2009)
The nation's current recession has strained the finances of local governments such that many cities with already delicate budgets have plunged into fiscal crisis. This dissertation examines three causes of fiscal crisis - ...
