Consonant landmark detection for speech recognition
(Massachusetts Institute of Technology, 2008)
This thesis focuses on the detection of abrupt acoustic discontinuities in the speech signal, which constitute landmarks for consonant sounds. Because a large amount of phonetic information is concentrated near acoustic ...
A model for firing patterns of auditory nerve fibers
(Massachusetts Institute of Technology, 1963)
A study of micromachined displacement pumps for vacuum generation
(Massachusetts Institute of Technology, 2011)
Micromachined vacuum pumps are one of the key components in miniature systems for chemical and biological analysis. Miniature sensors and analyzers are normally operated at the pressure range lower than a few millitorr. ...
Polycrystalline Si thin films and devices : I. Seed selection through ion channeling II. Thin-film transistors
(Massachusetts Institute of Technology, 1988)
Trees and beyond : exploiting and improving tree-structured graphical models
(Massachusetts Institute of Technology, 2011)
Probabilistic models commonly assume that variables are independent of each other conditioned on a subset of other variables. Graphical models provide a powerful framework for encoding such conditional independence structure ...
Analysis, modeling and design of energy management and multisource power systems
(Massachusetts Institute of Technology, 2011)
Transformative impacts on our energy security rely on creative approaches for consumption and generation of electricity. Technological contributions can impact both areas if they focus on problems of scale. For example, ...
Stochastic methods for large-scale linear problems, variational inequalities, and convex optimization
(Massachusetts Institute of Technology, 2013)
This thesis considers stochastic methods for large-scale linear systems, variational inequalities, and convex optimization problems. I focus on special structures that lend themselves to sampling, such as when the ...
Development of a monolithic very large scale optoelectronic integrated circuit technology
(Massachusetts Institute of Technology, 2000)
Optical interconnects have been proposed for use in high-speed digital systems as a means of overcoming the performance limitations of electrical interconnects at length scales ranging from one millimeter to one hundred ...
User interface handles for web objects
(Massachusetts Institute of Technology, 2013)
On the desktop, users are accustomed to having visible handles to objects that they can organize, share, and manipulate. Web applications today feature many loosely defined classes of such objects, like flight itineraries, ...
Template-based hardware-software codesign for high-performance embedded numerical accelerators
(Massachusetts Institute of Technology, 2013)
Sophisticated algorithms for control, state estimation and equalization have tremendous potential to improve performance and create new capabilities in embedded and mobile systems. Traditional implementation approaches are ...
