Analysis of High-order Approximations by Spectral Interpolation Applied to One- and Two-dimensional Finite Element Method [PDF]

open access: yesJournal of Applied and Computational Mechanics, 2020
The implementation of high-order (spectral) approximations associated with FEM is an approach to overcome the difficulties encountered in the numerical analysis of complex problems.

Orthogonal least squares algorithm for training multi-output radial basis function networks [PDF]

open access: yes, 1991
A constructive learning algorithm for multioutput radial basis function networks is presented. Unlike most network learning algorithms, which require a fixed network structure, this algorithm automatically determines an adequate radial basis function ...

Fréchet algebras with orthogonal basis [PDF]

open access: yesColloquium Mathematicum, 1984
A basis \(\{e_ n\}\) in a topological algebra is called orthogonal if \(e_ ne_ m=\delta_{nm}e_ n\)- a concept introduced by this reviewer and studied in collaboration with others. In their paper [Can. J. Math. 29, 270-276 (1977; Zbl 0348.46036)], \textit{J.

IN THE ISSUES OF MATHEMATICAL MODELLING LOGISTICS PROCESSES [PDF]

open access: yesActa Logistica, 2019
Mathematical modelling came to logistics from economics. Economic models have been used for quite some time, but the results obtained force us to develop new branches of the theory.

Orthogonal forward selection for constructing the radial basis function network with tunable nodes

open access: yes, 2005
An orthogonal forward selection (OFS) algorithm based on the leave-one-out (LOO) criterion is proposed for the construction of radial basis function (RBF) networks with tunable nodes.

Sparse multioutput radial basis function network construction using combined locally regularised orthogonal least square and D-optimality experimental design

open access: yes, 2003
A construction algorithm for multioutput radial basis function (RBF) network modelling is introduced by combining a locally regularised orthogonal least squares (LROLS) model selection with a D-optimality experimental design.

Mathematical model of dynamics of moving objects based on quaternions

open access: yesТехнічна інженерія, 2019
One of the main tasks of managing groups of dynamic moving objects is to ensure their consistent movement in space. It is advisable to optimize the movements (motion) in space using mathematical models i.e. systems of equations of motion.

An orthogonal terrain-following coordinate and its preliminary tests using 2-D idealized advection experiments [PDF]

open access: yesGeoscientific Model Development, 2014
We have designed an orthogonal curvilinear terrain-following coordinate (the orthogonal σ coordinate, or the OS coordinate) to reduce the advection errors in the classic σ coordinate.

SPICE-Based SAR Tomography over Forest Areas Using a Small Number of P-Band Airborne F-SAR Images Characterized by Non-Uniformly Distributed Baselines

open access: yesRemote Sensing, 2019
Synthetic aperture radar tomography (TomoSAR) has been proven to be a useful way to reconstruct vertical structure over forest areas with P-band images, on account of its three-dimensional imaging ability.
