Procedures for dealing with certain types of noise and systematic errors common to many Hadamard transform optical systems [PDF]

open access: yes
Sources of noise and error correcting procedures characteristic of Hadamard transform optical systems were investigated. Reduction of spectral noise due to noise spikes in the data, the effect of random errors, the relative performance of Fourier and ...

Projective surfaces not as Hadamard products and the dimensions of the Hadamard joins [PDF]

open access: yesarXiv
We study the dimensions of Hadamard products of $k\ge 3$ varieties if we allow to modify $k-1$ of them by the action of a general projective linear transformation. We also prove that the join of a variety not contained in a coordinate hyperplane with a ``nice'' curve always has the expected dimension.

The Robin problems for the coupled system of reaction–diffusion equations

open access: yesBoundary Value Problems
This article investigates the local well-posedness of Turing-type reaction–diffusion equations with Robin boundary conditions in the Sobolev space. Utilizing the Hadamard norm, we derive estimates for Fokas unified transform solutions for linear initial ...

Lagrange multiplier selection based on SATD for H.265/HEVC

open access: yesTongxin xuebao, 2017
In order to improve the coding performance of intra rough mode decision,a SATD-based Lagrange multiplier selection algorithm was proposed for H.265/HEVC.The characteristic of Hadamard transform was first analyzed,and following the new Lagrange multiplier
