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 ...
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 ...
Hybrid flow data center network architecture design and analysis
(Massachusetts Institute of Technology, 2017)
In this thesis, we propose a hybrid flow network architecture for future data center. The hybrid flow architecture has its origins in the early 1990s with studies on all-optical networks and fiber-optical computer networks. ...
Architectures for photon-mediated quantum information processing
(Massachusetts Institute of Technology, 2018)
In this thesis, I present architectures for quantum information processing where photons are used as the quantum bit (qubit) or for mediating entanglement between other qubits. The emphasis of this research is to simplify ...
Iterative methods, combinatorial optimization, and linear programming beyond the universal barrier
(Massachusetts Institute of Technology, 2015)
In this thesis we consider fundamental problems in continuous and combinatorial optimization that occur pervasively in practice and show how to improve upon the best known theoretical running times for solving these problems ...
Broadband terahertz photonics
(Massachusetts Institute of Technology, 2014)
In recent years, quantum cascade lasers have emerged as mature semiconductor sources of light in the terahertz range, the frequency range spanning 1 to 10 THz. Though technological development has pushed their operating ...
Aggregation and influence in teams of imperfect decision makers
(Massachusetts Institute of Technology, 2014)
Bayesian hypothesis testing inevitably requires prior probabilities of hypotheses. Motivated by human decision makers, this thesis studies how binary decision making is performed when the decision-making agents use imperfect ...
