On orthogonal polynomials and related discrete integrable systems [PDF]

open access: yes, 2006
Orthogonal polynomials arise in many areas of mathematics and have been the subject of interest by many mathematicians. In recent years this interest has often arisen from outside the orthogonal polynomial community after their connection with ...

Orthogonal Polynomials, Paraorthogonal Polynomials, and Point Perturbation [PDF]

open access: yes, 2009
This thesis consists of three parts. Part 1 starts with an introduction to orthogonal polynomials, to be followed by some well-known theorems pertinent to the results we shall discuss.

A constructive model of orthogonal axonometry [PDF]

open access: yesFacta Universitatis. Series: Architecture and Civil Engineering, 2003
A new method for object representation in arbitrary orthogonal axonometry is suggested. Constructions for a point drawing are shown, using two rotations - a rotation of the coordinate plane Oxy to the profile plane and a rotation of the profile plane to ...

The Accurate Method for Computing the Minimum Distance between a Point and an Elliptical Torus

open access: yesComputers, 2016
We present an accurate method to compute the minimum distance between a point and an elliptical torus, which is called the orthogonal projection problem.

SOLID IMAGE EXTRACTION FROM LIDAR POINT CLOUDS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
In laser scanner architectural surveying it is necessary to extract orthogonal projections from the tridimensional model, plans, elevations and cross sections.

Mixed Compressive Sensing Back-Projection for SAR Focusing on Geocoded Grid

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
This article presents a new scheme called 2-D mixed compressive sensing back-projection (CS-BP-2D), for synthetic aperture radar (SAR) imaging on a geocoded grid, in a single measurement vector frame.

An Effective Adaptive Combination Strategy for Distributed Learning Network

open access: yesApplied Sciences, 2021
In this paper, we develop a modified adaptive combination strategy for the distributed estimation problem over diffusion networks. We still consider the online adaptive combiners estimation problem from the perspective of minimum variance unbiased ...

Orthogonal Projections Based on Hyperbolic and Spherical n-Simplex

open access: yesAdvances in Mathematical Physics, 2015
Orthogonal projection along a geodesic to the chosen k-plane is introduced using edge and Gram matrix of an n-simplex in hyperbolic or spherical n-space. The distance from a point to k-plane is obtained by the orthogonal projection.

A convergent nonlinear splitting via orthogonal projection [PDF]

open access: yes, 1984
summary:We study the convergence of the iterations in a Hilbert space $V,x_{k+1}=W(P)x_k, W(P)z=w=T(Pw+(I-P)z)$, where $T$ maps $V$ into itself and $P$ is a linear projection operator.

Dual‐view 3D human pose estimation without camera parameters for action recognition

open access: yesIET Image Processing, 2021
The purpose of 3D human pose estimation is to estimate the 3D coordinates of key points of the human body directly from images. Although multi‐view based methods have better performance and higher precision of coordinate estimation than a single‐view ...
