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 ...
Friction under microscope with trapped ions in optical lattices
(Massachusetts Institute of Technology, 2016)
In recent years, cold-atom experiments have moved towards atomic systems with increasingly stronger interactions. One goal is to emulate condensed-matter phenomena in an ultimately controlled system by studying the motion ...
Effective mechanical Properties of material models with random heterogeneities
(Massachusetts Institute of Technology, 2016)
In this thesis we obtain analytical approximations to the probability distribution of the elastic tensor and fracture strengths of material models with random heterogeneities. We start by investigating the effective elastic ...
Shape memory ceramics in small volumes
(Massachusetts Institute of Technology, 2016)
Shape memory ceramics rely on martensitic transformations which are similar to those found in metallic shape memory materials, but ceramics offer several advantages over metals such as higher operating temperatures and ...
Regulation of microtubule attachment at the kinetochore and cell cortex
(Massachusetts Institute of Technology, 2016)
During mitosis, the cell divides in two, evenly distributing the genetic material and splitting the rest of cellular contents between the resulting daughter cells. This process is essential, rapid, and complex, requiring ...
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. ...
