Speech Representation Models for Speech Synthesis and Multimodal Speech Recognition
(Massachusetts Institute of Technology, 2016)
The field of speech recognition has seen steady advances over the last two decades, leading to the accurate, real-time recognition systems available on mobile phones today. In this thesis, I apply speech modeling techniques ...
Cryptographically enforced access control for user data in untrusted clouds
(Massachusetts Institute of Technology, 2016)
Modern web services rob users of low-level control over cloud storage; a user's single logical data set is scattered across multiple storage silos whose access controls are set by the web services, not users. The result ...
Advanced data bus architecture using CDMA for highly reliable systems
(Massachusetts Institute of Technology, 2007)
Conventional fault-tolerant architectures require extensive cross-strapping of redundant modules. The purpose of this thesis is to prove the feasibility of the use of code division multiple access (CDMA) to permit shared ...
Development and application of a 4-dimensional Computed Tomography simulator
(Massachusetts Institute of Technology, 2007)
This thesis presents the development and application of a 4-Dimensional Computed Tomography (4D CT) simulation program. The simulation is used to understand and quantify the sources of image artifacts that arise from ...
Fourier-Motzkin with non-linear symbolic constant coefficients
(Massachusetts Institute of Technology, 2016)
The polyhedral framework is an elegant and useful system for reasoning about loop nests in programs, and is commonly used to perform complex loop transformations such as tiling and parallelization. However, several critical ...
Analysis of harmonic distortion in an Integrated Power System for naval applications
(Massachusetts Institute of Technology, 2005)
This research quantifies the voltage distortion over the broad range of operating conditions experienced by a Naval warship. A steady state model of an Integrated Power System (IPS) was developed in a commercially available ...
Spatiotemporal processing and time-reversal for underwater acoustic communications
(Massachusetts Institute of Technology, 2005)
High-rate underwater acoustic communication can be achieved using transmitter/receiver arrays. Underwater acoustic channels can be characterized as rapidly time-varying systems that suffer severe Inter Symbol Interferences ...
The outsourcing and offshoring competitive landscape and its uncertainties
(Massachusetts Institute of Technology, 2005)
The outsourcing and offshoring competitive landscape is rapidly and constantly evolving, presenting new challenges and opportunities for providers and customers alike. Outsourcing providers are pressured to increase the ...
Prognostic models for mesothelioma : variable selection and machine learning
(Massachusetts Institute of Technology, 2005)
Malignant pleural mesothelioma is a rare and lethal form of cancer affecting the external lining of the lungs. Extrapleural pneumonectomy (EPP), which involves the removal of the affected lung, is one of the few treatments ...
Game theoretic analysis and agent-based simulation of electricity markets
(Massachusetts Institute of Technology, 2005)
In power system analysis, uncertainties in the supplier side are often difficult to estimate and have a substantial impact on the result of the analysis. This thesis includes preliminary work to approach the difficulties. ...
