An endoscope is an invaluable tool to interpret conditions within a body. Flexible endoscopes are controlled by a set of rotational knobs requiring a doctor's hands to guide and locate the view. This research uses a combination of a camera, facial recognition techniques and software to create a hands-free gesture recognition application for use by a physician to probe the internals of a human b...

This survey reviews the large and growing literature on copula-basedmodels for economic and financial time series. Copula-basedmultivariatemodels allow the researcher to specify the models for the marginal distributions separately from the dependence structure that links these distributions to form a joint distribution. This allows for a much greater degree of flexibility in specifying and esti...

Their small size and ease of use makes Personal Digital Assistants (PDAs) very attractive for inclusion as clients in mobile multimedia applications. Alas, the cost for integration of PDA in distributed multimedia systems is high, as the resource limitations on PDA require client adaptation, and as software development on PDA is comparatively expensive. We present PocketWeb, a tool facilitating...

When combined with realtime knowledge of user context and goals, haptic feedback can contribute to the need for transparent, appropriately salient information display in information-rich pervasive environments. Designed with respect for human perceptual and attentional limits, it can serve as a “background” communication channel by freeing visual resources, and being naturally suitable for low-...

We present the Forensic Analysis ToolKit (FATKit)–a modular, extensible framework that increases the practical applicability of volatile memory forensic analysis by freeing human analysts from the prohibitively-tedious aspects of low-level data extraction. FATKit allows analysts to focus on higherlevel tasks by providing novel methods for automatically deriving digital object definitions from C...

This paper describes the design and development of an interactive multimedia simulator for pre-operational setup procedures on a computer numerically controlled turning center. This is part of an effort to develop training tools to supplement the online education program offered at the University of Houston. The benefits of such a simulator is that it acts as a computer based training tool for ...

Subluxation of the capsular tension ring (CTR) into the vitreous is a rare complication. The explantation of these rings from the vitreous by conventional vitrectomy is often a difficult procedure requiring great surgical skill. We report two cases of posteriorly subluxated endocapsular rings, which were explanted with pars plana vitrectomy using the chandelier illumination system. This illumin...

The development of mobility aids for the blind is a challenging task that has a number of potential solutions. Direct electrical stimulation of the visual cortex has been used to generate ‘phosphenes’ (perceived as flashes of light) that can, with training, be interpreted as low resolution images. A second approach is to use a grid of tactile stimulators to represent an array of pixels. Thirdly...

GP (for Graph Programs) is a rule-based, nondeterministic programming language for solving graph problems at a high level of abstraction, freeing programmers from handling low-level data structures. The core of GP consists of four constructs: single-step application of a set of conditional graphtransformation rules, sequential composition, branching and iteration. We present a formal semantics ...
