Riffle : an efficient communication system with strong anonymity
(Massachusetts Institute of Technology, 2015)
Anonymous communication is an important part of democratic societies and freedom of speech. Whistleblowers, protest organizers, and, more broadly, anyone with controversial viewpoints have been using the limited form of ...
Spoken language understanding in a nutrition dialogue system
(Massachusetts Institute of Technology, 2015)
Existing approaches for the prevention and treatment of obesity are hampered by the lack of accurate, low-burden methods for self-assessment of food intake, especially for hard-to-reach, low-literate populations. For this ...
Numerical field simulation for parallel transmission in MRI at 7 tesla
(Massachusetts Institute of Technology, 2011)
Parallel transmission (pTx) is a promising improvement to coil design that has been demonstrated to mitigate B1* inhomogeneity, manifest as center brightening, for high-field magnetic resonance imaging (MRI). Parallel ...
Observational learning with finite memory
(Massachusetts Institute of Technology, 2011)
We study a model of sequential decision making under uncertainty by a population of agents. Each agent prior to making a decision receives a private signal regarding a binary underlying state of the world. Moreover she ...
An analysis of incentive strategies for single-source suppliers to drive cost reduction
(Massachusetts Institute of Technology, 2011)
An organization's decision on which aspects of its operations to outsource represents a key, strategic issue that should be based on maximizing performance throughout the entire value chain. In certain instances strategic ...
Monitoring and evaluating reorder point system performance : a cost-weighted approach
(Massachusetts Institute of Technology, 2011)
Organizations are quickly realizing the need to leverage data and analytics to stay one step ahead of the competition as fast-paced global markets continue to emerge and grow and the world becomes increasingly complex. ...
A pressure versus displacement measurement system
(Massachusetts Institute of Technology, 2000)
Superconducting nanowire single-photon detectors on aluminum nitride photonic integrated circuits
(Massachusetts Institute of Technology, 2017)
With recent advances in integrated single-photon sources and quantum memories, onchip integration of high-performance single-photon detectors becomes increasingly important. The superconducting nanowire single-photon ...
Interactive visualization of big data leveraging databases for scalable computation
(Massachusetts Institute of Technology, 2013)
Modern database management systems (DBMS) have been designed to efficiently store, manage and perform computations on massive amounts of data. In contrast, many existing visualization systems do not scale seamlessly from ...
Iron (III) Chloride doping of large-area chemical vapor deposition graphene
(Massachusetts Institute of Technology, 2013)
Chemical doping is an effective method of reducing the sheet resistance of graphene. This thesis aims to develop an effective method of doping large area Chemical Vapor Deposition (CVD) graphene using Iron (III) Chloride ...
