Microstructured tungsten thermophotovoltaic selective emitters c by Natalija (Zorana) Jovanović.
(Massachusetts Institute of Technology, 2008)
This research investigates the fabrication, modeling, characterization, and application of tungsten two-dimensional (2D) photonic crystal (PhC) structures as selective emitters and means of achieving higher efficiencies ...
Intelligence by design : principles of modularity and coordination for engineering complex adaptive agents
(Massachusetts Institute of Technology, 2001)
All intelligence relies on search - for example, the search for an intelligent agent's next action. Search is only likely to succeed in resource-bounded agents if they have already been biased towards finding the right ...
Quantization and erasures in frame representations
(Massachusetts Institute of Technology, 2006)
Frame representations, which correspond to overcomplete generalizations to basis expansions, are often used in signal processing to provide robustness to errors. In this thesis robustness is provided through the use of ...
A dual/high-voltage automotive electrical power system with superior transient performance
(Massachusetts Institute of Technology, 2000)
Today's automotive electrical power system is based on an engine-driven alternator regulated at 14 V which charges a 12 V battery and delivers power to the loads. Installed electrical power is growing rapidly with model ...
Novel photonic phenomena in nanostructured material systems with applications and mid-range efficient insensitive wireless energy-transfer
(Massachusetts Institute of Technology, 2008)
A set of novel mechanisms for the manipulation of light in the nanoscale is provided. In the class of all-dielectric material systems, techniques for the suppression of radiative loss from incomplete-photonic-bandgap ...
Existence and stability analysis of ferroresonance using the generalized state-space averaging technique
(Massachusetts Institute of Technology, 2000)
Ferroresonance can induce an undesired over-voltage often accompanied with a phase reversal which can damage power distribution transformers and motors and cause injury to the system operators. Similarly, under some ...
Radio frequency dc-dc power conversion
(Massachusetts Institute of Technology, 2007)
THIS THESIS addresses the development of system architectures and circuit topologies for dc-dc power conversion at very high frequencies. The systems architectures that are developed are structured to overcome limitations ...
Stochastic matched field processing for localization and nulling of acoustic sources
(Massachusetts Institute of Technology, 2000)
Multivariable analysis of spectral measurements for the characterization of semiconductor processes
(Massachusetts Institute of Technology, 2001)
The availability of affordable and reliable optical sensor technology and the abundance of data that these sensors now provide have created new opportunities to better characterize and control semiconductor processes in ...
Predicting gene function from images of cells
(Massachusetts Institute of Technology, 2007)
This dissertation shows that biologically meaningful predictions can be made by analyzing images of cells. In particular, groups of related genes and their biological functions can be predicted using images from large ...
