Image deblurring aims to restore the detailed texture information or structures from blurry images, which has become an indispensable step in many computer vision tasks. Although various methods have been proposed deal with image problem, most of them treated as a whole and neglected characteristics different frequencies. In this paper, we present new method called multi-scale frequency separat...

Building on works of Berthé–Steiner–Thuswaldner and Fogg–Nous, we show that the two-dimensional torus, Lebesgue almost every translation admits a natural coding such associated subshift satisfies Boshernitzan criterion. As consequence, for these torus translations, quasi-periodic potential can be approximated uniformly by one which Schrödinger operator has Cantor spectrum zero measure. We also ...

Long-range spatial coherence can be induced in incoherent thermal emitters by embedding a periodic grating within material supporting propagating polaritons or dielectric modes. However, only single spatially coherent mode is supported purely emitters. While various designs have been proposed for the purpose of allowing arbitrary emission profiles, limitations associated with partial are not kn...

This work is devoted to solving a fundamental scientific problem – the development of foundations and methodology for creating prototype hardware software complex noninvasive detection localization pathologies living human tissues based on dynamic radiothermic mapping, designed early diagnosis oncological diseases monitoring their treatment processes, can also be used in personalized medicine. ...

In this paper, we consider a constant envelope (CE) pilot-based low-complexity technique for frequency synchronization in multi-user massive MIMO systems. Study of the complexity-performance trade-off shows that this CE-pilot-based technique provides better MSE performance when compared to existing low-complexity high-PAPR pilot-based CFO (carrier frequency offset) estimator. Numerical study of...
