In this work we set upon showing theoretically that the use of accelerating spatiotemporal Quasi-Phase-Matching (QPM) in media with parametric optical interactions makes it possible to generate a time-reversed replica of the pump pulse envelope in a frequency converted component. We construct the geometrical form for the modulation that will lead to an up-converted envelope-time-reversed replic...

The local binary pattern (LBP) provides a simple and efficient approach to gray-scale and rotation invariant texture classification. However, the LBP operator thresholds P neighbors at the value of the center pixel in a local neighborhood and employs a P-bit binary pattern to encode only the signs of the differences between the gray values. Thus, the LBP operator discards some important texture...

We propose here a large homogeneous calorimeter as the next generation neutrino detector for ν factories and/or conventional ν beams. The active media is chosen to be water for obvious economical reasons. The Čerenkov light produced in water is sufficient to have good energy resolution, and the pattern recognition is realized by a modular water tank structure. Monte Carlo simulations demonstrat...
