Mobile obesity study
(Massachusetts Institute of Technology, 2009)
The prevalence of overweight and obesity has steadily increased over the years among all genders, ages, racial and ethnic groups, educational levels, and smoking levels [15]. From 1960 to 2004, the prevalence of overweight ...
Developing an abstraction layer for the visualization of HSMM-based predictive decision support
(Massachusetts Institute of Technology, 2009)
Hidden semi-Markov models (HSMMs) have been previously proposed as real-time operator behavior prediction models that could be used by a supervisor to detect future anomalous behaviors. Because of the disconnect between ...
The future of game Al : learning to use human tactics
(Massachusetts Institute of Technology, 2009)
Many video games require artificial players that can act as replacements for human players. With today's constant increases in the complexity of games and the prevalence of user-created content, creating an Al that is ...
Image annotation with discriminative model and annotation refinement by visual similarity matching
(Massachusetts Institute of Technology, 2009)
A large percentage of photos on the Internet cannot be reached by search engines because of the absence of textual metadata. Such metadata come from description and tags of the photos by their uploaders. Despite of decades ...
A fourth order [Sigma] [Delta] bandpass modulator
(Massachusetts Institute of Technology, 2009)
A fourth order bandpass [Sigma] [Delta] modulator is proposed to digitize signals from a MEMS gyroscope. The modulator samples the amplitude-modulated signal at eight times the carrier frequency and achieves an SNR of 82dB ...
Temporal characterization of patient state with applications to prediction of tachycardia in anesthesia via induction of inhaled desflurane
(Massachusetts Institute of Technology, 2001)
It has always been assumed that using clinically measurable parameters is the most efficient way to characterize patient state. By adding additional sensors, monitors, and derived statistics (e.g. mean arterial blood ...
Dynamic load-balancing of StreamIt cluster computations
(Massachusetts Institute of Technology, 2006)
This thesis discusses the design and implementation of a dynamic load-balancing mechanism for computationally distributed programs running on a cluster written in the StreamIt programming language. StreamIt is useful for ...
Translating timed I/O automata specifications for theorem proving in PVs
(Massachusetts Institute of Technology, 2006)
The timed input/output automaton modeling framework is a mathematical framework for specification and analysis of systems that involve discrete and continuous evolution. In order to employ an interactive theorem prover in ...
Dynamic scan chains : a novel architecture to lower the cost of VLSI test
(Massachusetts Institute of Technology, 2003)
Fast developments in semiconductor industry have led to smaller and cheaper integrated circuit (IC) components. As the designs become larger and more complex, larger amount of test data is required to test them. This results ...
Language generation and speech synthesis in dialogues for language learning
(Massachusetts Institute of Technology, 2004)
Since 1989, the Spoken Language Systems group has developed an array of applications that allow users to interact with computers using natural spoken language. A recent project of interest is to develop an interactive ...
