Cellular phones offer a whole range of interesting and exciting possibilities for entertainment systems coupled with a very resource-constrained environment. In this article we consider the possibilities currently achievable through the example of a networked sports service. Applications that keep users up-to-date with sports results and playing fantasy(More)

Decades of research have explored factors that can influence green behavior. However, much less is known about how technology in general, and social technologies in particular can motivate people to participate in green activities. In this paper we describe the goals, design and evaluation of StepGreen.org, a site intended to promote energy-saving(More)
The vision of the Internet of Things, wherein everyday objects are embedded with smart wireless sensor devices, is making these sensor devices increasingly pervasive. As the density of their deployment in overlapping or adjacent areas increases, the contention for the unlicensed 2.4 GHz ISM band will also increase. To deal with the crowded spectrum, nodes(More)
This paper describes an SMS based text messaging system that delivers real time bus information to users' mobile phones. Many public transit systems provide schedule and fare information on their web sites, and a small subset of these have recently experimented with bus stop countdown displays. In contrast, an SMS based delivery system allows users to(More)
Electroencephalography (EEG) can be used as an indicator of fatigue. Several studies have shown that slow wave brain activities, delta (0-4 Hz) and theta (4-8 Hz), increase as an individual becomes fatigued, while the fast brain activities, alpha (8-13 Hz) and beta (13-35 Hz), decrease. However, an EEG is a complex piece of equipment that is generally used(More)
Advance scheduling of electricity markets could create a conflict between reliability requirements and market operations. Unlike the case for the real-time market alone, an independent system operator charged with preserving system reliability may face a new computational challenge in balancing the requirements of markets and system security. A bid-based,(More)
In this paper, we present an effective algorithm for reassembling three-dimensional apictorial jigsaw puzzles obtained by dividing a curved surface into a finite number of interlocking pieces. As such, our algorithm does not make use of any picture or design that may be painted on the surface; nor does it require a priori knowledge of the overall shape of(More)
