Statistical optimization of acoustic models for large vocabulary speech recognition
(University of Missouri--Columbia, 2006)
This dissertation investigates optimization of acoustic models in speech recognition. Two new optimization methods are proposed for phonetic decision tree (PDT) search and Hidden Markov modeling (HMM)-- the knowledge-based ...
Visualizing biochemical networks with Netview
(University of Missouri--Columbia, 2006)
Networks are modelled as graphs and are represented visually using graph-drawing algorithms. Visualization of such big networks help biologists understand them. In this paper, we present a Java 3d-based visualization toolkit ...
Adaptive clustering and transmission range adjustment for topology control in wireless sensor networks
(University of Missouri--Columbia, 2006)
A wireless sensor network (WSN) is characterized by a limited energy supply and a large number of nodes. Topology control (TC) as one of the main ways to control energy consumption in WSNs has been the focus of a considerable ...
Wireless sensor network aided search and rescue in trails
(University of Missouri--Columbia, 2006)
In recent years, wireless sensor networks have been used in applications of data gathering and target localization across large geographical areas. In this thesis, we study the issues involved in applying wireless sensor ...
Sylview: a visualization system for forest management
(University of Missouri--Columbia, 2006)
In the field of forestry, the output of forest growth models provide a wealth of detailed information that can often be difficult to analyze and perceive due to presentation either as plain text summary tables or static ...
Adaptive bilateral extensor for image interpolation
(University of Missouri--Columbia, 2006)
A novel algorithm for image interpolation, referred to as adaptive bilateral extensor interpolation, is proposed in this thesis. It combines useful features of an extensor based algorithm, utilizing a non-linear mapping ...
Real-time visualization of massive imagery and volumetric datasets
(University of Missouri--Columbia, 2006)
The visualization of extremely large multi-dimensional datasets requires highly scalable geometric algorithms. We consider an algorithm to be scalable if its complexity remains constant independent of the size of the ...
Thermal image analysis using calibrated video imaging
(University of Missouri--Columbia, 2006)
This research work introduces new techniques for temperature measurement that utilizes visual spectrum of light. A periscope with a CCD camera is used to capture the image from a high temperature gas fired furnace and ...
