The Wireless Sensor Networks (WSN) particularly for real time applications raise fundamental problems for the scientific community. These problems are related to the limit of energy resource and the real time constraints on the communication delay. The well functioning of such networks depends mainly on the network lifetime result of nodes energies and the communication delay which should meet ...

Major innovations are becoming available for research in language development and disorders. Among these innovations, recent tools allow naturalistic recording in children’s homes and automated analysis to facilitate representative sampling. This study employed all-day recordings during the 2nd year of life in a child exposed to three languages, using a fully wearable battery-powered recorder, ...

We consider a real time data acquisition and processing multiserver system with identical servers (such as unmanned aerial vehicles, machine controllers, overhearing devices, medical monitoring units, etc.) which can be maintained/programmed for different kinds of activities (e.g. passive or active). This system provides a service for real time tasks arriving via several channels (such as surve...

Awareness of others’ interests can lead to fruitful collaborations, friendships and positive social change. Interviews of groups involved in both research and corporate work revealed a lack of awareness of shared interests among workers sharing an organizational affiliation and collocated in the same building or complex but still physically separated (e.g., by walls or floors). Our study showed...

By two years of age, toddlers are adept at recruiting social, observational, and linguistic cues to discover the meanings of words. Here, we ask how they fare in impoverished contexts in which linguistic cues are provided, but no social or visual information is available. Novel verbs are presented in a stream of syntactically informative sentences, but the sentences are not embedded in a social...

Recently, several efficient power-aware routing protocols have been developed for Mobile Ad Hoc Networks. While the MTPR (Minimum Total Transmission Power Routing) scheme attempts to reduce the total transmission power per packet, the MMBCR (Min-Max Battery Cost Routing) scheme tries to consider the remaining battery power of nodes to prolong the lifetime of each node. Since it is difficult for...

As computing devices and their users become increasingly mobile, the demand for information about the environment, or context, becomes of significant importance. Applications must be able to adapt themselves to the changing environment to satisfy users’ demands and to ensure that the application’s resource usage matches the environment’s capabilities. However, using traditional means, acquiring...

Conscious awareness is an infrequent complication of general anesthesia. All methods of anesthesia have been implicated, and no method guarantees amnesia. This article examines implicit and explicit memory and discusses factors associated with awareness. Common methods of detection are unreliable, and symptoms resembling post-traumatic stress disorder may result if awareness goes unrecognized a...

This paper proposes a novel communication protocol, called Many-to-One Sensors-to-Sink (MOSS), tailored to wireless sensor networks (WSNs). It exploits the unique sensors-to-sink traffic pattern to realize low-overhead medium access and lowlatency sensors-to-sink routing paths. In conventional schedule-based MAC protocols such as S-MAC, sensor nodes in the proximity of the event generate report...
