Wireless Sensor Networks (WSNs) offer inherent packet redundancy since each point within the network area is covered by more than one sensor node. This phenomenon, which is known as sensors co-coverage, is used in this paper to detect unauthenticated events. Unauthenticated event broadcasting in a WSN imposes network congestion, worsens the packet loss rate, and increases the network energy con...

This Paper describes the generalised structure of Force-Sensor-less Power assist control (FSPAC) which is an essential technology to design a feedback control system in a human friendly way. Paper clarifies regarding generalised structure of Force-Sensor-less power assist control using two force observer. The Force, which is used to assist the control system is estimated by using encoders inste...

Many real life problems are characterized by the structure of data derived from multiple sensors. The sensors may be independent, yet their information considers the same entities. Thus, there is a need to efficiently use the information rendered by numerous datasets emanating from different sensors. A novel methodology to deal with such problems is suggested in this work. Measures for evaluati...

Urban areas are complex systems, comprising many interacting infrastructure sectors. Understanding these inter-relationships is essential to sustainable urban and infrastructure development. Research focused on single sectors, or over limited timescales, will inevitably fail to capture these interdependencies and dynamics. Consequently this project is carrying out work to investigate these sect...

This paper proposes an algorithm for visual-inertialcamera pose tracking, using adaptive recursive particle filtering.The method benefits from the agility of inertial-based androbustness of vision-based tracking. A proposal distribution hasbeen developed for the selection of the particles, which takes intoaccount the characteristics of the Inertial Measurement Unit(IMU) ...

The voltage sensitivity of voltage-gated cation channels is primarily attributed to conformational changes of a four transmembrane segment voltage-sensing domain, conserved across many levels of biological complexity. We have identified a remarkable point mutation that confers significant voltage dependence to Kir6.2, a ligand-gated channel that lacks any canonical voltage-sensing domain. Simil...

Positioning can be done by means of triangulation in which triples of position-aware nodes estimate a neighbor’s position with the help of distances. If a larger number of nodes exist, multiple position estimates can be averaged to yield a more precise mean position. Rather than applying equal weights to each position estimate, we propose an unequal weighting scheme which emphasizes those summa...

In over deployed sensor networks, one approach to Conserve energy is to keep only a small subset of sensors active at Any instant. For the coverage problems, the monitoring area in a set of points that require sensing, called demand points, and consider that the node coverage area is a circle of range R, where R is the sensing range, If the Distance between a demand point and a sensor node is l...
