Diagnostic and therapeutic devices and applications of endoscopic optical coherence tomography
(Massachusetts Institute of Technology, 2018)
There is an increased demand for developing transformative technologies to satisfy unmet needs in the clinical management of a number of gastrointestinal (GI) tract diseases. With the maturation of sweptsource lasers, OCT ...
Computation by block copolymer self-assembly
(Massachusetts Institute of Technology, 2018)
Unconventional computation is a paradigm of computation that uses novel information tokens from natural systems to perform information processing. Using the complexity of physical systems, unconventional computing systems ...
Derivation, experimental verification, and applications of a new color image model
(Massachusetts Institute of Technology, 2018)
Image modeling is an important area of image processing. Good image models are useful, for example, in image restoration problems because they provide constraints that can be imposed on degraded images to retrieve better ...
Energy-efficient circuits and systems for computational imaging and vision on mobile devices
(Massachusetts Institute of Technology, 2018)
Eighty five percent of images today are taken by cell phones. These images are not merely projections of light from the scene onto the camera sensor but result from a deep calculation. This calculation involves a number ...
Multiscale methods for fabrication design
(Massachusetts Institute of Technology, 2018)
Modern manufacturing technologies such as 3D printing enable the fabrication of objects with extraordinary complexity. Arranging materials to form functional structures can achieve a much wider range of physical properties ...
Financial signal processing : applications to asset-market dynamics and healthcare finance
(Massachusetts Institute of Technology, 2018)
The seemingly random fluctuations of price and value produced by information flow and complex interactions across a diverse population of stakeholders has motivated the extensive use of stochastic processes to analyze both ...
Model order reduction for stochastic models of biomolecular systems with time-scale separation
(Massachusetts Institute of Technology, 2018)
Biomolecular systems often involve reactions that take place on different time-scales, giving rise to 'slow' and 'fast' system variables. This property is widely used in the analysis of systems to obtain dynamical models ...
Towards practical policies for network control
(Massachusetts Institute of Technology, 2018)
In the past three decades, several network control policies geared towards achieving throughput optimality have been developed. However, rarely any of these policies have been used in practice. We study three different ...
Emulsification, separation, and manipulation of oil-water systems using condensation, electrocoalescence, and electrowetting
(Massachusetts Institute of Technology, 2018)
This thesis explores the emulsification, separation, and manipulation of oil/water mixtures using a range of chemical, mechanical, and electrical techniques. Simply explained, this thesis reports new methods to emulsify ...
Preventing data leakage in web services
(Massachusetts Institute of Technology, 2018)
Web services like Google, Facebook, and Dropbox are a regular part of users' lives. However, using these applications can cause sensitive data leakage both on the server and client. On the server-side, applications collect ...
