Pediatric Emergency Care, 1992
The expression of cardiac dysfunction in pediatric patients with myocarditis may not be conspicuous. While older children with myocarditis may abruptly present with pleuritic or angina-like pain, infants and toddlers with fulminant disease are unable to verbalize such complaints.

A Model Predictive Approach to Fault-Tolerant WASNs
2009 Fifth International Conference on Networking and Services, 2009In Wireless Ad hoc Sensor Networks (WASNs), a crucial issue is to reduce power consumption while satisfying some key network properties. In this paper, we propose a fault-tolerant topology control that optimizes the lifetime of the network at a given degree k of connectivity by minimizing power consumption. Our topology control is fully distributed and

Optimization and Evaluation of an Energy-Efficient MAC Protocol for WASNs
2010 Sixth International Conference on Networking and Services, 2010A Wireless Ad hoc Sensor Network (WASN) is an autonomous collection of low cost devices that communicate over wireless links. This devices are often powered by limited energy resources, and it is expensive and sometimes infeasible to recharge or replace them. Hence, energy efficiency is the main design concern for such a network. In literature, several

Weighted Action-coupled Semantic Network (wASN) for robot intelligence
2008 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2008Semantic knowledge especially for robots is often used as a form of knowledge representation which includes ontological knowledge to support description logics and rule language. However, it is difficult to design rules which provide some goal-associated context, object and space (COS)-action complexes to be used to infer alternative attempts for ...

Privacy Preserving Second-order Consensus for WASNs
2018 37th Chinese Control Conference (CCC), 2018Considering the privacy requirements on initial states for second-order consensus in wireless sensor and actuator networks (WSAN s), we focus on the design of one privacy-preserving second-order consensus (PPSC) protocol in a distributed way, and investigate this issue from both the viewpoints of limiting the kind of information to be broadcasted and ...

Spatial Statistical Analysis of Urban Noise Data from a WASN Gathered by an IoT System: Application to a Small City [PDF]
Applied Sciences (Switzerland), 2016 EU Directive 49/2002 and Spanish law 37/2006 urge cities to develop strategic noise maps and action plans to evaluate noise exposure and to establish noise abatement procedures in critical areas. However, noise mapping involves costly and cumbersome measurement procedures that can become a real issue in practice.

Trenton Limestone – The Karst that Wasn′t there, or was it?
1993Abstract The top surface of the Trenton Limestone and equivalent carbonate units has be variously described as a subaerial exposure surface (paleokarst), a submarine erosion surface, and a submarine hardground. Detailed study of the contact between the carbonates and overlying shale in outcrop and core and regional stratigraphic ...

An interference aware multi-channel MAC protocol for WASN
2017 International Conference on Innovations in Electrical Engineering and Computational Technologies (ICIEECT), 2017Wireless sensors network is a network consists of sensors node, creating cluster and selection of cluster head is an issue for an efficient WSN. A new technique is proposed in this research which is termed as Wireless Active Sensors Network (WASN). We designed a novel protocol called interference aware Multi channel protocol based on MAC for sensors ...

Performance analysis of MVDR beamformer in WASN with sampling rate offsets and blind synchronization
2015 23rd European Signal Processing Conference (EUSIPCO), 2015In wireless acoustic sensor networks (WASNs), sampling rate offsets (SROs) between nodes are inevitable, and recognized as one of the challenges that have to be resolved for a coherent array processing. A simplified free-space propagation is considered with a single desired source impinging a WASNs from the far-field and contaminated by a diffuse noise.
