Degradation mechanisms of GaN high electron mobility transistors
(Massachusetts Institute of Technology, 2007)
In spite of their extraordinary performance, GaN high electron mobility transistors (HEMT) have still limited reliability. In RF power applications, GaN HEMTs operate at high voltage where good reliability is essential. ...
A novel positioning system for accurate tracking in indoor environments
(Massachusetts Institute of Technology, 2007)
Precise positioning is crucial to many applications involving autonomous robots in indoor environments. Current solutions to the indoor localization problem are either both highly unreliable and inaccurate (like GPS based ...
A stochastic tractography system and applications
(Massachusetts Institute of Technology, 2007)
Neuroscientists hypothesize that the pathologies of some neurological diseases are associated with neuroanatomical abnormalities. Diffusion Tensor Imaging (DTI) and stochastic tractography allow us to investigate white ...
A network development and runtime environment for StarLogo TNG
(Massachusetts Institute of Technology, 2007)
StarLogo: The Next Generation aims to introduce students to programming. The StarLogo application is frequently used in a classroom setting, but the effectiveness of StarLogo is limited as long as students cannot interact ...
Resolution limits and process latitude of comformable contact nano-lithography
(Massachusetts Institute of Technology, 2007)
Conformable Contact Lithography enables researchers to attain high-resolution lithographic patterning at manageable cost. This thesis characterizes the minimum resolvable feature size and process latitude of Conformable ...
Strained SiGe-channel p-MOSFETs : impact of heterostructure design and process technology
(Massachusetts Institute of Technology, 2007)
Conventional Si CMOS intrinsic device performance has improved by 17% per year over the last 30 years through scaling of the gate length of the MOSFET along with process innovations such as the super-steep retrograde channel ...
Markov chain Monte Carlo and its applications to phylogenetic tree construction
(Massachusetts Institute of Technology, 2007)
This thesis addresses the application of Bayesian methods to problems in phylogenetics. Specifically, we focus on using genetic data to estimate phylogenetic trees representing the evolutionary history of genes and species. ...
Predicting confusions and intelligibility of noisy speech
(Massachusetts Institute of Technology, 2007)
Current predictors of speech intelligibility are inadequate for making predictions of speech confusions caused by acoustic interference. This thesis is inspired by the need for a capability to understand and predict speech ...
Where India fits within Flextronics global supply chain
(Massachusetts Institute of Technology, 2007)
This project focuses on Flextronics International manufacturing strategy regarding its global supply chain design, and its export strategy from India. It also focuses on the application of the Flextronics case to the ...
Life cycle cost modeling of automotive paint systems
(Massachusetts Institute of Technology, 2007)
Vehicle coating is an important component of automotive manufacturing. The paint shop constitutes the plurality of initial investment in an automotive assembly plant, consumes the majority of energy used in the plant's ...
