In this work wavelength sensitivity in mechanically induced long period fiber gratings (MLPFG) is analyzed. This analysis is first carried out both in standard single-mode fiber SMF-28 and in Er-doped fibers. The mechanical analysis for both types of fibers under different torsion conditions is presented. In order to apply the torsion one of the fiber ends(More)
In this work the recently developed fuzzy logic-based adaptive Kalman filter (FL-AKF) is used to build adaptive centralized, decentralized, and federated Kalman filters for Adaptive MultiSensor Data Fusion (AMSDF). The adaptation carried out is in the sense of adaptively adjusting the measurement noise covariance matrix of each local FL-AKF to fit the(More)
We describe a system aimed at the in-situ 3D annotation of physical objects and environments by the use of augmented reality. The system integrates absolute positioning technology, in the form of GPS and UWB positioning, with real-time computer vision to create a virtual 'incident map'. The virtual map is constructed collaboratively by multiple operatives(More)
The use of Smartphones (SPs)with Android Operating System (AOS) has reached unprecedented popularity. This is due to the many features that these devices offer as Internet connection, storage of information as well as the ability to perform diverse online transactions. As a result, these devices have become the main target of malware attacks that try to(More)
