Design of discrete-time filters for efficient implementation
(Massachusetts Institute of Technology, 2011)
The cost of implementation of discrete-time filters is often strongly dependent on the number of non-zero filter coefficients or the precision with which the coefficients are represented. This thesis addresses the design ...
Nonparametric choice modeling : applications to operations management
(Massachusetts Institute of Technology, 2011)
With the recent explosion of choices available to us in every walk of our life, capturing the choice behavior exhibited by individuals has become increasingly important to many businesses. At the core, capturing choice ...
Demonstration of monolithically integrated graphene interconnects for low-power CMOS applications
(Massachusetts Institute of Technology, 2011)
In recent years, interconnects have become an increasingly difficult design challenge as their relative performance has not improved at the same pace with transistor scaling. The specifications for complex features, clock ...
The method of multiplicities
(Massachusetts Institute of Technology, 2011)
Polynomials have played a fundamental role in the construction of objects with interesting combinatorial properties, such as error correcting codes, pseudorandom generators and randomness extractors. Somewhat strikingly, ...
Composable abstractions for synchronization in dynamic threading platforms
(Massachusetts Institute of Technology, 2011)
High-level abstractions for parallel programming simplify the development of efficient parallel applications. In particular, composable abstractions allow programmers to construct a complex parallel application out of ...
Characterization and modeling of nanocomposite thermoelectric materials system bismuth antimony telluride ((Biy̳Sb1̳-̳y̳)2̳Te3̳) as a function of temperature and magnetic field
(Massachusetts Institute of Technology, 2011)
This thesis looks at (BiySb1-y)2Te3 nanocomposites as an example of the currently available nano systems. In this thesis, (BiySb-y)2Te3 nanocomposites are characterized from ~325K down to ~3K. Advantages of this low ...
Grounding linguistic analysis in control applications
(Massachusetts Institute of Technology, 2012)
This thesis addresses the problem of grounding linguistic analysis in control applications, such as automated maintenance of computers and game playing. We assume access to natural language documents that describe the ...
Auto-tuning on the macro scale : high level algorithmic auto-tuning for scientific applications
(Massachusetts Institute of Technology, 2012)
In this thesis, we describe a new classification of auto-tuning methodologies spanning from low-level optimizations to high-level algorithmic tuning. This classification spectrum of auto-tuning methods encompasses the space ...
Information flow for secure distributed applications
(Massachusetts Institute of Technology, 2009)
Private and confidential information is increasingly stored online and increasingly being exposed due to human errors as well as malicious attacks. Information leaks threaten confidentiality, lead to lawsuits, damage ...
Probabilistic models for multi-view semi-supervised learning and coding
(Massachusetts Institute of Technology, 2009)
This thesis investigates the problem of classification from multiple noisy sensors or modalities. Examples include speech and gesture interfaces and multi-camera distributed sensor networks. Reliable recognition in such ...
