, 2023 Wave is a provably EUF-CMA (existential unforgeability under adaptive chosen message attacks) digital signature scheme based on codes [15]. It is a hash-and-sign primitive and its security is built according to a GPV-like framework [19] under two assumptions related to coding theory: (i) the hardness of finding a word of prescribed Hamming weight and ...

An Improved Numerical DBSCAN Algorithm Based on Non-IIDness Learning
IEEE Access, 2021 In clustering algorithm research, objects, attributes and other aspects of data sets are usually considered to be independent and identically distributed; that is, each object is assumed to be an independent and uniformly distributed individual with no ...

Parameter selection for HOTV regularization [PDF]
Applied Numerical Mathematics, 2018 Popular methods for finding regularized solutions to inverse problems include sparsity promoting $\ell_1$ regularization techniques, one in particular which is the well known total variation (TV) regularization. More recently, several higher order (HO) methods similar to TV have been proposed, which we generally refer to as HOTV methods. In this letter,

On Adaptive Grad-Div Parameter Selection
Journal of Scientific Computing, 2022 We propose, analyze and test a new adaptive penalty scheme that picks the penalty parameter $ε$ element by element small where $\nabla\cdot u^h$ is large. We start by analyzing and testing the new scheme on the most simple but interesting setting, the Stokes problem. Finally, we extend and test the algorithm on the incompressible Navier Stokes equation

Determination of Ellipsoidal Seed–Soil Interaction Parameters for DEM Simulation
AgricultureDuring precision sowing, the contact process between the soil and seeds cannot be ignored. The constitutive relationship of soil is relatively complex, with characteristics such as high nonlinearity, while the contact mechanism between the soil and seeds
