A tunable radial basis function model for nonlinear system identification using particle swarm optimisation [PDF]

open access: yes, 2009
A tunable radial basis function (RBF) network model is proposed for nonlinear system identification using particle swarm optimisation (PSO). At each stage of orthogonal forward regression (OFR) model construction, PSO optimises one RBF unit's centre ...

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.

The Influence of Beachrock Outcrop on Spatial Variability in Beach Morphology

open access: yesJournal of Marine Science and Engineering
Beachrock is a type of coastal carbonate sedimentary rock developed in the sandy beach intertidal zone, widely distributed along the beach front, and the loss of beach sediment is the main cause of beachrock exposure.

Spatiotemporal characteristics and abrupt changes of wind speeds in the Guangdong–Hong Kong–Macau Greater Bay Area

open access: yesEnergy Reports, 2022
Wind energy is a clean and pollution-free renewable energy source, particularly in coastal areas with abundant wind resources. To effectively plan for and invest in wind power development, accurate estimates of wind power (based on variable wind speeds ...

A discussion of empirical orthogonal functions and their application to vertical temperature profiles [PDF]

open access: yesTellus, 1967
It has been found that empirical orthogonal functions have a special application in the deduction of temperature soundings from radiometric measurements made by artificial satellites. The methods of Lorenz, Obukhov, and Holmstrom for the generation of empirical orthogonal functions are discussed and compared. These methods all reduce to that of solving

Reconstructing Sound Speed Profile From Remote Sensing Data: Nonlinear Inversion Based on Self-Organizing Map

open access: yesIEEE Access, 2021
By establishing a linear regression relationship between the projection coefficient of the empirical orthogonal function (EOF) of the sound speed profile (SSP) and remote sensing parameters of the sea surface, the single empirical orthogonal function ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Effectiveness of empirical orthogonal function used in decorrelation of GRACE time-variable gravity field

open access: yesGeodesy and Geodynamics, 2015
Empirical orthogonal function (EOF) was used to process the spherical harmonic coefficient (SHC) of 115 Gravity Recovery and Climate Experiment (GRACE) RL05 monthly gravity field models from March 2003 to February 2013 released by CSR (Center for Space ...

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient
