This work utilizes a statistical approach of Principal Component Analysis (PCA) towards the detection Methane (CH4)-Carbon Monoxide (CO) Poisoning occurring in coal mines, forest fires, drainage systems etc. where CH4 and CO emissions are very high closed buildings or confined spaces during oxidation processes. Both methane carbon monoxide highly toxic, colorless odorless gases. gases have thei...

A critical component of a multi-sensor system is sensor scheduling to optimize system performance under constraints (e.g. power, bandwidth, and computation). In this paper, we apply particle filter sequential Monte Carlo methods to implement multiple sensor scheduling for target tracking. Under the constraint that only one sensor can be used at each time step, we select a sequence of sensor use...

WirelessHART is a standard that has been developed by four major companies in control systems. They mainly deal with field devices and their monitoring and controlling aspects. In this chapter, components are any process devices. Sensor nodes are referred to as nodes or sensor nodes. The sensor nodes can be connected to a component to make it wireless. The sensor nodes are deployed in uniform d...

Pervasive advertising attracts attention in research and industry. Sensor information in this context is considered to improve the content communication of Pervasive Environments. This paper describes an architecture for integrating sensor information into Pervasive Environments. The sensor information is accessible through an abstraction layer, the Sensor Web, which is based on Web Service tec...

Carbon Monoxide (CO) is the most abundant air pollutant gas and accumulates rapidly to dangerous concentrations even in areas that seem to be well ventilated. Carbon monoxide detectors/alarm systems exist but people who are old, hearing impaired, partially sighted or heavy sleepers may not get the warning or find it difficult to wake up and get out in the event of dangerous concentration of CO ...

With the advancements in micro-electromechanical systems (MEMS) technologies, magnetic and inertial sensors are becoming more and more accurate, lightweight, smaller in size as well as low-cost, which in turn boosts their applications in human movement analysis. However, challenges still exist in the field of sensor orientation estimation, where magnetic disturbance represents one of the obstac...

In Escherichia coli, certain mutations in the cpxA gene (encoding a sensor kinase of a two-component signal transduction system) randomize the location of FtsZ ring assembly and dramatically affect cell division. However, deletion of the cpxRA operon, encoding the sensor kinase and its cognate regulator CpxR, has no effect on division site biogenesis. It appears that certain mutant sensor kinas...
