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 ...
Long-term, subdermal implantable EEG recording and seizure detection
(Massachusetts Institute of Technology, 2016)
Epilepsy is a common chronic neurological disorder that affects about 1% of the world population. Although electroencephalogram (EEG) has been the chief modality in the diagnosis and treatment of epileptic disorders for ...
Modeling the effects of systematic process variation of circuit performance
(Massachusetts Institute of Technology, 2001)
Single-site, noninvasive, blood pressure measurements at the ear using ballistocardiogram (BCG), and photoplethysmogram (PPG), and a low-power, reflectance-mode PPG SoC
(Massachusetts Institute of Technology, 2014)
This work presents a wearable congestive heart failure (CHF) monitor at the ear that uses the ballistocardiogram (BCG), electrocardiogram (ECG), and photoplethysmogram (PPG) to extract mean blood pressure up the Carotid ...
The scalable commutativity rule : designing scalable software for multicore processors
(Massachusetts Institute of Technology, 2014)
What fundamental opportunities for multicore scalability are latent in software interfaces, such as system call APIs? Can scalability opportunities be identified even before any implementation exists, simply by considering ...
