Algorithm for computation and visualization of weighted constrained Voronoi diagrams
(University of Missouri--Columbia, 2009)
A weighted Voronoi diagram (WVD) has been developed in order to regionalize or allocate space around a predetermined set of points or generators for the case that generator points have different weights reflecting their ...
Domain-concept mining : an efficient on-demand data mining approach
(University of Missouri--Columbia, 2008)
Traditional brute-force association mining approaches, when applied to large datasets, are thorough but inefficient due to computational complexity. A low global minimum probability threshold can worsen this complexity by ...
Genome scale meta analysis of microarrays for biological inferences
(University of Missouri--Columbia, 2009)
In this present era of high-throughput technologies, meta-analysis is being widely used to integrate multiple similar high throughput studies. Here we propose a novel framework for applying meta-analysis techniques on ...
Fast and adaptive H.264/AVC video coding for network based applications
(University of Missouri--Columbia, 2009)
As the state of the art video coding standard, H.264/AVC achieves significant coding performance gain comparing to its predecessors. Nevertheless, the advance comes at huge complexity increase of the encoder, which may ...
Data-driven 3D shape modeling
(University of Missouri--Columbia, 2010)
3D shape modeling is essential for computer to understand our real world. So far, 3D shaping modeling is still an open issue. There are too much raw data around, but there is no uniform or standard way to translate them ...
Automating database curation with workflow technology
(University of Missouri--Columbia, 2005)
Building scientific databases is extremely difficult and expensive. Costs could be reduced if the experts who curate the deposited data, are provided with data that are reviewed by other experts at lower levels for accuracy ...
A new approach to data backup
(University of Missouri--Columbia, 2010)
Backing up data in order to protect against its possible loss is important. As more and more data is stored the burden of storing large amounts of backup data becomes significant. This thesis discusses the design and ...
A fast multiple longest common subsequence (MLCS) algorithm
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Finding the longest common subsequence (LCS) of multiple strings is an NP-hard problem, with many applications in the areas of bioinformatics and ...
Building shape-shifting tries for fast IP lookup
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The Internet Protocol (IP) is a protocol used to communicate data over packet-switched internet works. The currently deployed version of the Internet ...
Confocal microscopy imaging analysis of plant morphodynamics
(University of Missouri--Columbia, 2010)
Pollen tubes are delivery mechanisms in a plant's reproductive cycle. Morphodynamic analysis of these microscopic structures provide biologists with insight into the inner workings of these structures. This thesis presents ...
Bioinformatics methods for protein identification using peptide mass fingerprinting data
(University of Missouri--Columbia, 2009)
Protein identification using mass spectrometry is an important yet partially solved problem in the study of proteomics during the post-genomic era. The major techniques used in mass spectrometry are Peptide Mass Fingerprinting ...
Integrate template matching and statistical modeling for continuous speech recognition
(University of Missouri--Columbia, 2011)
In this dissertation, a novel approach of integrating template matching with statistical modeling is proposed to improve continuous speech recognition. Commonly used Hidden Markov Models (HMMs) are ineffective in modeling ...
Statistical inference in wireless sensor and mobile networks
(University of Missouri--Columbia, 2010)
In recent years, wireless sensor networks have emerged as a cost effective alternative to traditional wired sensor systems. In the meantime, mobile networks have also gained many momentums. The two emerging networks share ...
PIR sensing array for fall detection
(University of Missouri--Columbia, 2011)
The purpose of the Fuzzy PIR Fall Detection Array is to keep the elderly safe by providing a means for an immediate response to falls while still allowing them to enjoy the same independence they felt before fall detection ...
Ensemble acoustic modeling in automatic speech recognition
(University of Missouri--Columbia, 2011)
In this dissertation, several new approaches of using data sampling to construct an Ensemble of Acoustic Models (EAM) for speech recognition are proposed. A straightforward method of data sampling is Cross Validation (CV) ...
Implementing X.509 security certificate based authentication in a virtual organization
(University of Missouri--Columbia, 2011)
In recent years, research institutions have shown great interest in forming Virtual Organizations (VO) as a cost effective alternative to maintaining dedicated resources for computationally intensive tasks. Shibboleth is ...
Providing multi-token based protection against cross site request forgery
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cross Site Request Forgery (CSRF) attacks occur when a malicious website forces a user's web browser to perform unwanted actions on a trusted website. ...
Mining host-pathogen interaction from biomedical literature
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] With infectious diseases affecting humans, animals, and plants, the knowledge on mechanisms of infection is critical in designing drugs as well as ...
Design of learning objects to support constructivist learning environments
(University of Missouri--Columbia, 2005)
Using Constructivism to guide the design of learning objects, we develop a generic structure that classifies knowledge into different types on different levels. With a simple generic structure of learning object, learners ...
Sketch-based navigation for mobile robots using qualitative landmark states
(University of Missouri--Columbia, 2007)
In this work, a system for navigating a mobile robot along a sketched route is proposed. The sketch is drawn on a PDA screen by a human operator and contains approximate landmarks and a path, similar to a sketch provided ...
