The drift strip method for improving the energy response of a CdZnTe (CZT) detector to hard X and gamma rays is discussed. Results for a 10x10x3 mm3 detector crystal demonstrate a remarkable improvement of the energy resolution. The full width at half maximum (FWHM) is 2.18 keV (3.6%), 2.45 keV (3.0%), 2.86 keV (0.8%) and 3.89 keV (0.6%) at 60 keV, 80 keV, 356 keV and 661 keV, respectively. The...

Employing five commuting sets of five-qubit observables, we propose specific 160−661 and 160−21 state proofs of the Bell-Kochen-Specker theorem that are also proofs of Bell’s theorem. A histogram of the ‘Hilbert-Schmidt’ distances between the corresponding maximal bases shows in both cases a noise-like behaviour. The five commuting sets are also ascribed a finite-geometrical meaning in terms of...

The problem is to determine the homographies between several images taken from a common camera location (but with di erent orientations) and then use these homographies to mosaic the images into a single wide angle image. RANSAC is to be used to determine the homographies with LevenbergMarquardt minimization used to re ne the results. Furthermore, the change in camera angle between each image s...
