Three essays in financial economics
(Massachusetts Institute of Technology, 2013)
Chapter 1 studies endogenous medium term cycles in a Schumpterian growth model. New firms are created by imitating existing firms and they drive the least productive firms out of business. In this manner, firm entry speeds ...
Incorporating operational flexibility into electric generation planning : impacts and methods for system design and policy analysis
(Massachusetts Institute of Technology, 2013)
This dissertation demonstrates how flexibility in hourly electricity operations can impact long-term planning and analysis for future power systems, particularly those with substantial variable renewables (e.g., wind) or ...
Quantum signal processing
(Massachusetts Institute of Technology, 2002)
Quantum signal processing (QSP) as formulated in this thesis, borrows from the formalism and principles of quantum mechanics and some of its interesting axioms and constraints, leading to a novel paradigm for signal ...
The thermodynamic properties of Markov processes
(Massachusetts Institute of Technology, 1985)
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 ...
Determining molecular conformation from distance or density data
(Massachusetts Institute of Technology, 2000)
The determination of molecular structures is of growing importance in modern chemistry and biology. This thesis presents two practical, systematic algorithms for two structure determination problems. Both algorithms are ...
Methods in wave propagation and scattering
(Massachusetts Institute of Technology, 2001)
Aspects of wave propagation and scattering with an emphasis on specific applications in engineering and physics are examined. Frequency-domain methods prevail. Both forward and inverse problems are considered. Typical ...
Control under communication constraints
(Massachusetts Institute of Technology, 2000)
Enhancing spectrum utilization through cooperation and cognition in wireless systems
(Massachusetts Institute of Technology, 2013)
We have seen a proliferation of wireless technologies and devices in recent years. The resulting explosion of wireless demand has put immense pressure on available spectrum. Improving spectrum utilization is therefore ...
Reconstruction algorithms for MRI
(Massachusetts Institute of Technology, 2013)
This dissertation presents image reconstruction algorithms for Magnetic Resonance Imaging (MRI) that aims to increase the imaging efficiency. Algorithms that reduce imaging time without sacrificing the image quality and ...
