Finding Bugs In Dynamic Web Applications
(2008-02-06)
Web script crashes and malformed dynamically-generated web pages are common errors, and they seriously impact usability of web applications. Currenttools for web-page validation cannot handle the dynamically-generatedpages ...
Exploiting Transport-Level Characteristics of Spam
(2008-02-15)
In the arms race to secure electronic mail users and servers fromunsolicited messages (spam), the most successful solutions employtechniques that are difficult for spammers to circumvent. Thisresearch investigates the ...
Learning Grammatical Models for Object Recognition
(2008-02-25)
Many object recognition systems are limited by their inability to share common parts or structure among related object classes. This capability is desirable because it allows information about parts and relationships in ...
Making Medical Records More Resilient
(2008-02-17)
Hurricane Katrina showed that the current methods for handling medicalrecords are minimally resilient to large scale disasters. This research presents a preliminary model for measuring the resilience of medical records ...
Learning in a virtual world : expanding activity theory for the design and evaluation of group praxis
(2008)
This text responds to the increasing demand for frameworks to support the design and evaluation of virtual worlds which are effective in their particular learning context by developing, a meta-theoretical framework for ...
Automated stock trading : a multi-agent, evolutionary approach
(2008)
Stock market trading has garnered much interest over the past few decades as it has been made easier for the general public to trade. It is certainly an avenue for wealth growth, but like all risky undertakings, it must ...
Co-present photo sharing on mobile devices
(2008)
This dissertation researches current approaches to photo sharing. We have found that most current methods of photo sharing are not as compelling as traditional photo sharing - with the increasing in popularity of digital ...
Accelerating genomic sequence alignment using high performance reconfigurable computers
(2008)
Reconfigurable computing technology has progressed to a stage where it is now possible to achieve orders of magnitude performance and power efficiency gains over conventional computer architectures for a subset of high ...
A Multi-Scale Generalization of the HoG and HMAX Image Descriptors for Object Detection
(2008-04-09)
Recently, several powerful image features have been proposed whichcan be described as spatial histograms of oriented energy. Forinstance, the HoG, HMAX C1, SIFT, and Shape Context feature allrepresent an input image using ...
Trajectory Analysis and Semantic Region Modeling Using A Nonparametric Bayesian Model
(2008-06-24)
We propose a novel nonparametric Bayesian model, Dual Hierarchical Dirichlet Processes (Dual-HDP), for trajectory analysis and semantic region modeling in surveillance settings, in an unsupervised way. In our approach, ...
