Signal Denoise Method Based on the Higher Order Cumulant and Local Tangent Space Mean Reconstruction [PDF]

open access: yesAdvanced Engineering Forum, 2011
In signal denoise method to nonlinear time series based on principle manifold learning, reduction target dimension is chosen at random, which cause low efficiency. Local low dimensional manifold is obtained by the eigenvalue decomposition to the covariance matrix, but covariance belongs to the second order statistics and cannot reflect the nonlinear ...

A Basic Inequality for the Tanaka-Webster Connection

open access: yesJournal of Applied Mathematics, 2012
For submanifolds tangent to the structure vector field in Sasakian space forms, we establish a Chen's basic inequality between the main intrinsic invariants of the submanifold (namely, its pseudosectional curvature and pseudosectional curvature on one ...

Uniqueness of asymptotically conical tangent flows

open access: yes, 2019
Singularities of the mean curvature flow of an embedded surface in R^3 are expected to be modelled on self-shrinkers that are compact, cylindrical, or asymptotically conical.

3D ball skinning using PDEs for generation of smooth tubular surfaces [PDF]

open access: yes, 2010
We present an approach to compute a smooth, interpolating skin of an ordered set of 3D balls. By construction, the skin is constrained to be C-1 continuous, and for each ball, it is tangent to the ball along a circle of contact.

New Modification on Heun’s Method Based on Contraharmonic Mean for Solving Initial Value Problems with High Efficiency

open access: yesJournal of Mathematics, 2020
In this paper, small modification on Improved Euler’s method (Heun’s method) is proposed to improve the efficiency so as to solve ordinary differential equations with initial condition by assuming the tangent slope as an average of the arithmetic mean ...

Tunable Magnetic and Electrical Properties of Cobalt and Zinc Ferrites CO1-XZnXFe2O4 Synthesized by Combustion Route [PDF]

open access: yesMaterials Research, 2018
Co and Zn ferrites with general formula CO1-XZnXFe2O4 (x = 0; 0,2 and 0,8) were synthesized by combustion reaction method, using urea as fuel. The structure of inverse-spinel-type ferrite were characterized through XRD using Rietveld refinement method to

Influence of Base Tangent Length Deviation on Nonlinear Dynamics Characteristic of Helical Gear System

open access: yesJixie chuandong, 2020
The design of the base tangent length deviation is generally selected according to the design manual. The study of the relationship between the base tangent length deviation design and the meshing dynamics performance has not been reported in literature.

DELP Treatment on Vision and Retinal Microcirculation in Patients With Acute Ischemic Stroke: Report of Five Cases and Literature Review

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.
