This paper provides a new viewpoint on the time and frequency dynamics of spillover effects among eight major world equity market indexes. We extend Diebold–Yilmaz approach Barunilk Krehik methodology to estimate measure skewness spillover. Our empirical results indicate that total is far smaller than volatility all markets. Although both vary with time, remains relatively smooth varies gradual...

We obtain upper bounds for the fourth and higher moments of short exponential sums involving Fourier coefficients holomorphic cusp forms twisted by rational additive twists with small denominators. conjectured best possible bound in case moment.

the goal of multi-frame super resolution (sr) is to fuse multiple low resolution (lr) images to produce one high resolution (hr) image. the major challenge of classic sr approaches is accurate motion estimation between the frames. to handle this challenge, fuzzy motion estimation method has been proposed that replaces value of each pixel using the weighted averaging all its neighboring pixels i...
