The precision calculating method of robots moving by the plane trajectories [PDF]

open access: yesInternational Journal of Advanced Robotic Systems, 2019
Robots with complex motion paths are very rarely designed. The main obstacle is the lack of the necessary mathematical apparatus, despite the fact that the theory was proposed by Newton. We managed to formulate a new method for obtaining linear transformation parameters.

On the moving plane method for nonlocal problems in bounded domains [PDF]

open access: yesJournal d'Analyse Mathématique, 2018
We consider a nonlocal problem involving the fractional laplacian and the Hardy potential, in bounded smooth domains. Exploiting the moving plane method and some weak and strong comparison principles, we deduce symmetry and monotonicity properties of positive solutions under zero Dirichlet boundary conditions.

Evaluation of the front-fixing method capabilities for numerical modelling of diffusion in moving systems [PDF]

open access: yes, 2008
Application of a finite difference front fixing method to various problems with moving boundaries and nonlinear material properties is discussed. Advantages and implementation problems of the method are highlighted.

The Moving Plane Method for Doubly Singular Elliptic Equations Involving a First-Order Term [PDF]

open access: yesAdvanced Nonlinear Studies, 2021
Abstract In this paper we deal with positive singular solutions to semilinear elliptic problems involving a first-order term and a singular nonlinearity. Exploiting a fine adaptation of the well-known moving plane method of Alexandrov–Serrin and a careful choice of the cutoff functions, we deduce symmetry and monotonicity properties of ...

Learning multi‐planar scene models in multi‐camera videos

open access: yesIET Computer Vision, 2015
Many man‐made environments are constructed with multiple levels where people walk, joined by stairs, ramps and overpasses. This study proposes a novel method to learn the geometry of a scene containing more than a single ground plane by tracking ...

Perspective Independent Ground Plane Estimation by 2D and 3D Data Analysis

open access: yesIEEE Access, 2020
Identifying the orientation and location of a camera placed arbitrarily in a room is a challenging problem. Existing approaches impose common assumptions (e.g. the ground plane is the largest plane in the scene, the camera roll angle is zero). We present

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.

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 )

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
