Point Defect Engineered Si Sub-Bandgap Light-Emitting Diode
(2007)
We extensively study the propagation features of higher-order modes in a photonic crystal fiber (PCF). Our analysis is based on a full-vector modal technique specially adapted to accurately describe light propagation in ...
Podcasting Computer Science E-1
(Association of Computing Machinery, 2007)
In recent months [teachers have] become publishers of content and students subscribers thereof by way of podcasts, feeds of audio, video, and other content that can be downloaded to clients like iTunes and devices like ...
Scratch for Budding Computer Scientists
(Association of Computing Machinery, 2007)
Scratch is a "media-rich programming environment" recently developed by MIT's Media Lab that "lets you create your own animations, games, and interactive art." Although Scratch is intended to "enhance the development of ...
Lexical Chaining and Word-Sense-Disambiguation
(2007)
Lexical chains algorithms attempt to find sequences of words in a document that are closely related semantically. Such chains have been argued to provide a good indication of the topics covered by the document without ...
Improving Performance Isolation on Chip Multiprocessors via an Operating System Scheduler
(IEEE Computer Society, 2007)
We describe a new operating system scheduling algorithm that improves performance isolation on chip multiprocessors (CMP). Poor performance isolation occurs when an application’s performance is determined by the behaviour ...
Chain: A Dynamic Double Auction Framework for Matching Patient Agents
(AI Access Foundation, 2007)
In this paper we present and evaluate a general framework for the design of truthful auctions for matching agents in a dynamic, two-sided market. A single commodity, such as a resource or a task, is bought and sold by ...
Online Mechanisms
(Cambridge University Press, 2007)
Online mechanisms extend the methods of mechanism design to dynamic environments with multiple agents and private information. Decisions must be made as information about types is revealed online and without knowledge of ...
Multi-Scale Capture of Facial Geometry and Motion
(Association for Computing Machinery, 2007)
We present a novel multi-scale representation and acquisition method for the animation of high-resolution facial geometry and wrinkles. We first acquire a static scan of the face including reflectance data at the highest ...
Exploring Defocus Matting: Nonparametric Acceleration, Super-Resolution, and Off-Center Matting
(Institute of Electrical and Electronics Engineers, 2007)
Defocus matting is a fully automatic and passive method for pulling mattes from video captured with coaxial cameras that have different depths of field and planes of focus. Nonparametric sampling can accelerate the ...
The Importance of Network Topology in Local Contribution Games
(Springer Verlag, 2007)
We consider a model of content contribution in peer-to-peer networks with linear quadratic payoffs and very general interaction patterns. We find that Nash equilibria of this game always exist; moreover, they are computable ...
