The significance of the seismic rotational components have been overlooked in the seismic evaluation of structural behavior. As researchers have measured seismic components more accurately using sensitive rotational velocity sensor, it was observed that the magnitude of rotational components is considerable and could not be neglected. Hence, some parts of seismic damage or failure of structures...

“Smart” and “attentive” services using users’ context are going to be realized in future ubiquitous computing environment. Sensor network is receiving considerable attention as one of the key technologies to keep track of the users’ context in the real world. Conventional sensor network research mainly aimed at environmental monitoring. However requirements of the sensor network infrastructure ...

Abstract The steady state responses of chemical sensors like the tin-oxide and composite conducting polymer sensors exhibit power law dependency on the vapor concentration. In this research, it is shown that linearization of measured (raw) sensor signals by an inverse power scaling improves class separability in feature space, hence the classification efficiency of electronic noses based on the...

In this paper, in order to increase the efficiency, to reduce the cost and to prevent the failures of wind turbines, which lead to an extensive break down, a robust fault diagnosis system is proposed for V47/660kW wind turbine operated in Manjil wind farm, Gilan province, Iran. According to the acquired data from Iran wind turbine industry, common faults of the wind turbine such as sensor fault...

We describe the design and use of an ontology for describing the Cactus framework — a component based architecture for scientific computing. This work forms a starting point for the use of ontologies to support new component applications involving multiple scale and models, realtime assimilation of sensor data and deployment on distributed Grids.

Abstract—The Zigduino is an open-source Arduino compatible microcontroller platform with an integrated 802.15.4 radio. The Loosely-coupled Component Infrastructure (LooCI) is a component-based middleware for building sensor network applications that runs on the Contiki operating system, which provides IPv6 networking. In this paper, we describe our approach to, and experiences of porting the Lo...

The network calculus is a powerful tool to analyze the performance of wireless sensor networks. But the original network calculus can only model the single-mode wireless sensor network. In this paper, we combine the original network calculus with the multimode model to analyze the maximum delay bound of the flow of interest in the multimode wireless sensor network. There are two combined method...

Sensor data on traffic events have prompted a wide range of research issues, related with the so-called ITS (Intelligent Transportation Systems). Data are delivered for both static (fixed) and mobile (embedded) sensors, generating large and complex spatiotemporal series. This scenario presents several research challenges, in spatio-temporal data management and data analysis. Management issues i...

For a wireless sensor network (WSN) with a large number of low-cost, battery-driven, multiple transmission power leveled sensor nodes of limited transmission bandwidth, then conservation of transmission resources (power and bandwidth) is of paramount importance. Towards this end, this paper considers the problem of power scheduling of Kalman filtering for general linear stochastic systems subje...

Wireless sensor networks are often located in areas where access to them is difficult or dangerous. Today, in wireless sensor networks, cluster-based routing protocols by dividing sensor nodes into distinct clusters and selecting local head-clusters to combine and send information of each cluster to the base station and balanced energy consumption by network nodes, get the best performance ...
