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)
In this paper, novel hybrid methodologies for modal parameters extraction using Empirical Mode Decomposition (EMD) based techniques combined with classic signal processing spectral analysis are presented. The modal frequencies are extracted by a methodology that combines EMD and Fast Fourier Transform (FFT). The damping factor is obtained by another(More)
The explosive growth of mobile technology has brought uncountable benefits to consumers, but it also presents new concerns and provides a platform for cybercrime. In the case of devices running the Android Operating System (OS), concerns have raised as Android has become a major OS in the market.
