Skinning with dual quaternions
(2007)Skinning of skeletally deformable models is extensively used for real-time animation of characters, creatures and similar objects. The standard solution, linear blend skinning, has some serious drawbacks that require ... -
Virtual shapers & movers: form and motion affect sex perception
(2007)An experiment to determine factors that influence the perceived sex of virtual characters was conducted. Four different model types were used: highly realistic male and female models, an androgynous character, and a ... -
A perceptual approach to trimming unstructured lumigraphs
(2007)We present a novel perceptual method to reduce the visual redundancy of unstructured lumigraphs, an image based representation designed for interactive rendering. We combine features of the unstructured lumigraph algorithm ... -
Using sensor networks for pedestrian detection
(2008)Pedestrian safety is a major concern in road transportation as pedestrian/vehicle accidents account for the second largest cause of traffic-related injuries and fatalities worldwide. Considerable work has examined the use ... -
Sensor network with delay tolerance (SeNDT)
(IEEE, 2007)As the technology underlying sensor networks becomes more advanced and reliable, ubiquitous computing will come closer to being a reality. This paper details the design and deployment of several sensor nodes that use ... -
Research issues in multiple policy optimization using collaborative reinforcement learning
(2007)Self-organizing techniques have successfully been used to optimize software systems, such as optimization of route stability in ad hoc network routing and optimization of the use of storage space or processing power using ... -
Self-adapting context definition
(2007)Many approaches to context-aware computing have focused on providing means for developers to define application contexts. In these approaches, correct application behavior depends on the developer defining the right contexts. ... -
Security considerations in a network management environment
(IEEE, 1994)Considers the security aspects of communication between two management processes operating in different management domains; identifies two major risks: the security of information exchanged during the management association, ... -
Introducing security aspects with model transformation
(IEEE Computer Society, 2005)Aspect Oriented Programming and subsequently Aspect Oriented Software Development have received great attention recently and constitutes an interesting field of research in computer science. The goal of this paper is ... -
Overlay networks : a scalable alternative for P2P
(IEEE, 2003)Overlay networks create a structured virtual topology above the basic transport protocol level that facilitates deterministic search and guarantees convergence. Overlay networks are evolving into a critical component for ... -
Instant messaging and presence management in mobile ad-hoc networks
(IEEE, 2004)The combination of real-time message delivery and presence awareness has to lead the rapid rise in popularity of Instant Messaging (IM) in recent years. The extension of IM to mobile ad-hoc networks certainly offers ... -
Secure routing for mobile ad-hoc networks
(IEEE, 2005)In this article we present a survey of secure ad hoc routing protocols for mobile wireless networks. A mobile ad hoc network is a collection of nodes that is connected through a wireless medium forming rapidly changing ... -
A cost analysis of optical IP switching in new generation optical networks
(IEEE, 2006)In this paper we propose a simple model that analyzes the cost saving achieved by optical IP switching (OIS), a novel optical architecture, compared to a conventional IP-over-WDM network, where the IP router connects ... -
Cognitive radio: value creation and value migration
(2006)This paper develops the concept of a telecommunications value-chain and explores the many ways in which the valuechain can be altered by reconfigurable software-defined radios, cognitive radios and cognitive networks. ... -
Feasibility of flow-based optical provisioning in GEANT
(Optical Society of America, 2007)We present a novel network architecture that establishes dynamic optical paths by analyzing local network traffic. We demonstrate its feasibility and effectiveness through a network analysis using real traces collected ... -
A policy-driven trading framework for market-based spectrum assignment
(IEEE, 2007)We present a policy-driven trading framework for market-based spectrum assignment. Our work allows spectrum consumers to get exclusive access rights through payment of a fee, for a given period of time, and for a given ... -
Dynamic optical path allocation in multi-layer traffic engineering
(2007)Hybrid electro-optical architectures have been recently proposed as cost-effective solution to challenge nearfuture traffic demands. We believe that IP routing technology can be closely integrated with optical circuit ...
