recently different approaches have been developed in the field of sensor fault diagnostics based on auto-associative neural network (aann). in this paper we present a novel algorithm called self reconstructing auto-associative neural network (s-aann) which is able to detect and isolate single faulty sensor via reconstruction. we have also extended the algorithm to be applicable in multiple faul...

The standards developed by the Open Geospatial Consortium (OGC) provide a broad foundation for web-based geographical applications. As one of these the OGC Sensor Web Enablement (SWE), which comprises standards for the consumerand provider-oriented sensor viewpoint, allows data requests of real-time sensor measurements and observations, abstracting from the inherent sensor particularities. The ...

The purpose of this article is to present the development of a wind farm, with a condition monitoring system (CMS) based on control charts as the algorithm, centred on a new index, to prevent soil pollution by oil spills in wind farms. To this end, temperature sensors can be considered as one of the more significant sensors to be employed in this study, because the information obtained with reg...

Many application domains are adopting sensor networks as a viable computation platform with which to solve problems. A recent study indicates the global market for wireless sensor networks would grow tenfold by 2011 [3]. Currently sensor networks are being used for applications ranging from environmental monitoring [7, 17] and elderly monitoring [23] to seismic analysis of structures [1,14] and...

a feasible and fast method to fabricate hydrogen peroxide sensor was investigated by graphene-manganase nanocomposite carbone paste electrode. in the present work, in first step, the graphene was synthesized by chemical method and in second step, manganese oxide nanoparticle was doped on graphene. graphene-manganase nanocomposite was characterized by ftir and sem. the nanocomposite shows a high...

Data delivery is a major function of sensor network applications. Many applications, such as military surveillance, requires the detection of interested events to be reported to command center within in specified time frame, and therefore imposes a hard real-time bound on communication delay. On the other hand, to conserve energy, one of the most effective approaches is to transit sensor nodes ...

A novel potentiometric ion-selective PVC membrane sensor for analysis of atorvastatin (AT) in pharmaceutical preparations based on atorvastatin-(tetraphenyl borate), (AT-(TPB)2) as sensing element, tetraphenyl borate as additive and tris-2-ethyl-hexyl phosphate (TOP) as plasticizer solvent was prepared. The electrode shows a good Nernestian response over the concentration range of 0.09–5586 µ...
