Empirical Physics‐Based Normal Behavior Modeling of Drive Train Temperatures With High‐Resolution Wind Turbine Operating Data

open access: yesWind Energy, EarlyView.
ABSTRACT The installed wind energy capacity increases every year. However, operation and maintenance costs still make up a considerable portion of the levelized costs of electricity. This costs can be greatly reduced by the application of suitable early fault detection methods. The supervisory control and data acquisition system of wind turbines is one

Improved high-precision regional marine geomagnetic anomaly field model using Legendre polynomial expansion

open access: yesAIP Advances
Regional geomagnetic field models can provide detailed insights into the geomagnetic field and are of substantial value for precise maritime navigation and the detection of marine targets. In light of the polynomial model’s numerous advantages, including

On integral equations with Weakly Singular kernel by using Taylor series and Legendre polynomials

open access: yesOpen Physics, 2015
This paper is concerned with the numerical solution for a class of weakly singular Fredholm integral equations of the second kind. The Taylor series of the unknown function, is used to remove the singularity and the truncated Taylor series to second ...

Evolutionary Dynamic Multiobjective Optimisation Assisted by Inverse Regression Tree Predictor

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Dynamic multiobjective optimisation problems (DMOPs) are optimisation problems with multiple conflicting objectives that can change over time. Most dynamic multiobjective optimisation evolutionary algorithms (DMOEAs) attempt to estimate Pareto‐optimal sets (PS) directly in the decision space.

A Posteriori Error Estimation and Adaptive Taylor Series Methods for Nonlinear Function Approximation

open access: yesMathematics
The Taylor approximation theorem is a fundamental tool in numerical analysis, providing a local polynomial representation of smooth functions. In practical computations, a function f is approximated by a finite Taylor polynomial Pn, and controlling the ...

Pointwise Reconstruction of Wave Functions from Their Moments through Weighted Polynomial Expansions: An Alternative Global-Local Quantization Procedure

open access: yesMathematics, 2015
Many quantum systems admit an explicit analytic Fourier space expansion, besides the usual analytic Schrödinger configuration space representation. We argue that the use of weighted orthonormal polynomial expansions for the physical states (generated ...

DISCO: a general software tool for dislocation contrast factor calculations in diffraction analysis

open access: yesJournal of Applied Crystallography, EarlyView.
DISCO is a program capable of calculating the X‐ray contrast factor for single‐ and polycrystalline materials in real time.Dislocation contrast factors (CFs) play a central role in diffraction‐based analyses of plastic deformation, linking the elastic strain fields generated by dislocations to diffraction line broadening.

Wage reactions to regional and national unemployment

open access: yesRegional Science Policy &Practice, EarlyView., 2023
Abstract This paper analyses the entire wage effects of unemployment for an especially long observation period. In a three‐step approach, the wage reaction at the national level (wage‐setting curve or aggregate wage equation) is added to the reaction at the regional level (wage curve). Spatial models with instrumental variables are used.
