A New Simplification Algorithm for Point Cloud Based on the Vertical Plane Constraint and Moving Window

open access: yesIEEE Access, 2022
Using three-dimensional spatial information, this method constructs the detection condition, compares the conditions to be detected, formed by the points in the file to be simplified, then determines the redundancy of the points.

Some remarks on the method of moving planes

open access: yesDifferential and Integral Equations, 1998
The article deals with a nonlinear elliptic equation in divergence form given in a bounded domain with the homogeneous Dirichlet boundary condition. The domain is symmetric with respect to a hyperplane, symmetry and monotonicity properties of coefficient functions of the equation are supposed. The author proposes a variational approach to the method of

Liouville type theorems for the system of fractional nonlinear equations in R + n ${R^{n}_{+}}$

open access: yesJournal of Inequalities and Applications, 2016
In this paper we consider the following system of fractional nonlinear equations in the half space R + n ${R^{n}_{+}}$ : 1 { ( − Δ ) α 2 u 1 ( x ) = x n γ u 1 α 1 ( x ) u 2 β 1 ( x ) , x ∈ R + n , ( − Δ ) α 2 u 2 ( x ) = x n γ u 1 α 2 ( x ) u 2 β 2 ( x )

Complete treatment of single-photon emission in planar channeling

open access: yes, 2019
Approximate solutions of the Dirac equation are found for ultrarelativistic particles moving in a periodic potential, which depends only on one coordinate, transverse to the largest component of the momentum of the incoming particle.

Performance of a TMD to Mitigate Wind-Induced Interference Effects between Two Industrial Chimneys

open access: yesActuators, 2021
The present paper studies the performance of a tuned mass damper (TMD) installed in a 183 m tall chimney located at the edge of the wake shed by another chimney. Numerical and experimental results are available.

Self-shrinkers with a rotational symmetry

open access: yes, 2011
In this paper we present a new family of non-compact properly embedded, self-shrinking, asymptotically conical, positive mean curvature ends $\Sigma^n\subseteq\mathbb{R}^{n+1}$ that are hypersurfaces of revolution with circular boundaries.

Personalized Selumetinib Dosing in Pediatric Neurofibromatosis Type 1: Insights From a Pilot Therapeutic Drug Monitoring Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Objective To evaluate selumetinib exposure using therapeutic drug monitoring (TDM) in pediatric patients with neurofibromatosis type 1 (NF1) and plexiform neurofibromas (PN), assess interpatient pharmacokinetic variability, and explore the relationship between drug exposure, clinical response, and adverse effects.

About an analogue of Neifeld’s connection on the space of centred planes with one-index basic-fibre forms

open access: yesДифференциальная геометрия многообразий фигур, 2019
This research is realized by Cartan — Laptev method (with prolonga­tions and scopes, moving frame and exterior forms). In this paper we con­sider a space П of centered m-planes (a space of all centered planes of the dimension m). This space is considered

A novel updating modelling methodology for free-form surface modifications in the early stages of design [PDF]

open access: yes, 2003
The paper describes the first implementation of a method in which an initial CAD model is updated from a physical model. The method is based on image-mapping in which an initial CAD model is updated from images of a soft rapid prototype model (RPM) which
