Over the past 15 years, there has been an exponential growth of new technologies for indoor positioning and navigation. Unlike GNSS technology, which has become the leading solution for outdoor positioning, no technology has taken the lead indoors. With the price drop of radio beacons, we see massive deployment of beacons' networks for positioning....
Near infrared spectroscopy combined with multivariate calibration such as partial least squares regression is a promising technique for on-line monitoring of anaerobic digesters. Different substrates are used in digesters, depending on their availability and their methanogen potential, to optimize the process. In Europe, the feedstock for anaerobic...

In this paper, the use of a Moving Horizon Estimator (MHE) is investigated to address a class of state estimation problems dealing with multi-rate sensor fusion in presence of time-delayed measurements. As it makes use of a batch of past measurement and state estimates, MHE is indeed a good candidate to deal with ”missing” measurements.Nevertheless...
Using Fourier methods to reconstruct the phase measured by a wavefront sensor (WFS) can significantly re- duce the number of computations required, as well as easily enable predictive reconstruction methods based on knowledge of the adaptive optics system, atmospheric turbulence and wind profile. Previous work on Fourier re- construction has focuse...
