Capacity provisioning, failure recovery and throughput analysis for low earth orbit satellite constellations
(Massachusetts Institute of Technology, 2002)
We investigate the capacity needed to build a restorable satellite network and design routing schemes to achieve high throughput. Specifically, the first part of this thesis considers the link capacity requirement for a ...
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 ...
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 ...
Inertio-elastic focusing of bioparticles in a microchannel at ultra-high throughput
(Massachusetts Institute of Technology, 2014)
Many biological and industrial fluids are filled with micro-scale particles that can serve as "state markers" for real-world issues, such as human health and public infrastructure. In order to extract this valuable information ...
Automatic intrusion recovery with system-wide history
(Massachusetts Institute of Technology, 2014)
Compromises of our computer systems are inevitable. New software vulnerabilities are discovered and exploited daily, but even if the software is bug-free, administrators may inadvertently make mistakes in configuring ...
