Low power data-dependent transform video and still image coding
(Massachusetts Institute of Technology, 1999)
This work introduces the idea of data dependent video coding for low power. Algorithms for the Discrete Cosine Transform (DCT) and its inverse are introduced which exploit statistical properties of the input data in both ...
Distributed coordination in network information theory
(Massachusetts Institute of Technology, 2001)
Constructing a large-scale wireless data network is spectacularly expensive. It is therefore important to understand how to efficiently utilize the physical infrastructure and available battery power, which are expensive ...
Information theoretic analysis of watermarking systems
(Massachusetts Institute of Technology, 2001)
Watermarking models a copyright protection mechanism where an original data sequence is modified before distribution to the public in order to embed some extra information. The embedding should be transparent (i.e., the ...
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 ...
Modeling the effects of systematic process variation of circuit performance
(Massachusetts Institute of Technology, 2001)
An electromechanical valve drive incorporating a nonlinear mechanical transformer
(Massachusetts Institute of Technology, 2003)
In traditional internal combustion engines, a camshaft acts on the valve stems to open and close the valves. Valve timing is fixed relative to piston position. On the other hand, if a valve is flexibly controlled by a ...
Organic photovoltaics and concentrators
(Massachusetts Institute of Technology, 2008)
The separation of light harvesting and charge generation offers several advantages in the design of organic photovoltaics and organic solar concentrators for the ultimate end goal of achieving a lower cost solar electric ...
Effective software testing with a string-constraint solver
(Massachusetts Institute of Technology, 2009)
This dissertation presents techniques and tools for improving software reliability, by using an expressive string-constraint solver to make implementation-based testing more effective and more applicable. Concolic testing ...
