Video Super-resolution Reconstruction Algorithm Based on Total Variation Regularization
Chemical Engineering Transactions, 2015 A video super-resolution (SR) reconstruction algorithm based on total variation (TV) regularization is proposed in this paper. With the analysis of image degradation, the image formation model is introduced. Total variation method is chosen to regularize

Range-based estimation of quadratic variation [PDF]
, 2006 This paper proposes using realized range-based estimators to draw inference about the quadratic variation of jump-diffusion processes. We also construct a range-based test of the hypothesis that an asset price has a continuous sample path. Simulated data shows that our approach is efficient, the test is well-sized and more powerful than a return-based ...

Quadratic magneto-optical effect in hexagonal non-collinear antiferromagnets
AIP Advances, 2021 Quadratic magneto-optical (MO) effects can be utilized to investigate the spin order in antiferromagnetic (AFM) materials; however, the previously reported studies were all limited in antiferromagnets with collinear AFM order.

Variational quadratic shape functions for polygons and polyhedra
ACM Transactions on Graphics, 2022 Solving partial differential equations (PDEs) on geometric domains is an important component of computer graphics, geometry processing, and many other fields. Typically, the given discrete mesh is the geometric representation and should not be altered for simulation purposes.

On quadratic Gauss sums and variations thereof
Cogent Mathematics, 2015 A number of new terminating series involving $\sin(n^2/k)$ and $\cos(n^2/k)$ are presented and connected to Gauss quadratic sums. Several new closed forms of generic Gauss quadratic sums are obtained and previously known results are generalized.

International Journal of Naval Architecture and Ocean Engineering, 2018 In this study, the second order bending moment induced by sea waves is calculated using the quadratic strip theory. The theory has the fluid forcing terms including the quadratic terms of the hydrodynamic forces and the Froude–Krylov forces.
