Medium Access Control with Coordinated Adaptive Sleeping for Wireless Sensor Networks

by Wei Ye, John Heidemann, Deborah Estrin - IEEE/ACM Transactions on Networking , 2004
"... This paper proposes S-MAC, a medium access control (MAC) protocol designed for wireless sensor networks. Wireless sensor networks use battery-operated computing and sensing devices. A network of these devices will collaborate for a common application such as environmental monitoring. We expect senso ..."

Cognitive networks

by Ryan W. Thomas, Luiz A. DaSilva, Allen B. MacKenzie - IN PROC. OF IEEE DYSPAN 2005 , 2005
"... This paper presents a definition and framework for a novel type of adaptive data network: the cognitive network. In a cognitive network, the collection of elements that make up the network observes network conditions and then, using prior knowledge gained from previous interactions with the network ..."

The PHANToM haptic interface: A device for probing virtual objects

by Thomas H. Massie, J. K. Salisbury - Proceedings of the ASME Dynamic Systems and Control Division , 1994
"... This paper describes the PHANTOM haptic interface- a device which measures a user’s finger tip position and exerts a precisely controlled force vector on the finger tip. The device has enabled users to interact with and feel a wide variety of virtual objects and will be used for control of remote ma ..."

Matrix Completion with Noise

by Emmanuel J. Candès, Yaniv Plan
"... On the heels of compressed sensing, a remarkable new field has very recently emerged. This field addresses a broad range of problems of significant practical interest, namely, the recovery of a data matrix from what appears to be incomplete, and perhaps even corrupted, information. In its simplest ..."

form, the problem is to recover a matrix from a small sample of its entries, and comes up in many areas of science and engineering including collaborative filtering, machine learning, control, remote sensing, and computer vision to name a few. This paper surveys the novel literature on matrix

Gaia: A Middleware Infrastructure to Enable Active Spaces

by Manuel Román, Christopher Hess, Renato Cerqueira, Roy H. Campbell, Klara Nahrstedt - IEEE Pervasive Computing , 2002
"... We envision a future where people’s living spaces are interactive and programmable. Users interact with their offices, homes, cars, malls and airports to request information, benefit from the resources available, and configure the habitat’s behavior. Data and tasks are always accessible and are mapp ..."

and are mapped dynamically to convenient resources present in the current location. Users may extend the habitat with personal devices that seamlessly integrate with the environment. Such user-oriented interactive environments may require a novel software infrastructure to operate their resources, sense context

Contour enhancement, short-term memory, and constancies in reverberating neural networks

by Stephen Grossberg - Studies in Applied Math , 1973
"... A model of the nonlinear dynamics of reverberating on-center off-surround networks of nerve cells, or of cell populations, is analysed. The on-center off-surround anatomy allows patterns to be processed across populations without saturating the populations ' response to large inputs. The signal ..."

An Electronically Tunable Resonator for Noise Control

by Clark J. Radcliffe, Charles Birdsong , 2001
"... Many engineering systems create unwanted noise that can be reduced by the careful application of engineering noise controls. When this noise travels down tubes and pipes, a tuned resonator can be used to muffle noise escaping from the tube. The classical examples are automobile exhaust and ventilati ..."

Authenticating Pervasive Devices with Human Protocols

by Ari Juels, Stephen A. Weis , 2005
"... Abstract. Forgery and counterfeiting are emerging as serious security risks in low-cost pervasive computing devices. These devices lack the computational, storage, power, and communication resources necessary for most cryptographic authentication schemes. Surprisingly, low-cost pervasive devices lik ..."
