Accessibility and Serviceability Assessment to Inform Offshore Wind Energy Development and Operations off the US East Coast

open access: yesWind Energy, Volume 29, Issue 7, July 2026.
ABSTRACT The economic success of offshore wind energy projects relies on accurate projections of the construction and operations and maintenance (O&M) costs. These projections must consider the logistical complexities introduced by adverse met‐ocean conditions that can prohibit access to the offshore assets for sustained periods of time.

Functions of Minimal Norm with the Given Set of Fourier Coefficients

open access: yesMathematics, 2019
We prove the existence and uniqueness of the solution of the problem of the minimum norm function ∥ · ∥ ∞ with a given set of initial coefficients of the trigonometric Fourier series c j , j = 0 , 1 , … , 2 n ...

Distributed Acoustic Sensing (DAS) Waveforms: Effects of Source Signature, Geometry, and Attenuation

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Distributed acoustic sensing (DAS) records strain integrated over a finite gauge length depending on incidence angle, frequency, material velocities, fiber curvature, and gauge length. The DAS responses to a monofrequency plane wave of these are well understood.

Approximate method for calculating a thickwalled cylinder with rigidly clamped ends

open access: yesE3S Web of Conferences, 2018
Numerous papers dealing with the calculations of cylindrical bodies [1 -8 and others] have shown that analytic and numerical-analytical solutions in both homogeneous and inhomogeneous thick-walled shells can be obtained quite simply, using expansions in ...

Learning Situation for the Trigonometric Fourier Series from a Socio-epistemological Stand Point [PDF]

open access: yes, 2019
This article aims at showing a didactic proposal that favours the signification of the Trigonometric Fourier Series through a learning situation, based on the Socio-epistemological Theory of Mathematics Education, on research where this knowledge has ...

Boas’ Formula and Sampling Theorem

open access: yesAxioms, 2015
In 1937, Boas gave a smart proof for an extension of the Bernstein theorem for trigonometric series. It is the purpose of the present note (i) to point out that a formula which Boas used in the proof is related with the Shannon sampling theorem; (ii) to ...

On Summation of Fourier Series in Finite Form Using Generalized Functions

open access: yesMathematics
The problem of obtaining a final expression for a function initially given in the form of a trigonometric Fourier series is considered. We consider a special case of a series when the coefficients of the series are known and are rational functions of the

Strong convergence theorems for two-parameter Walsh-Fourier and trigonometric-Fourier series [PDF]

open access: yes, 1996
The martingale Hardy space $H_p([0,1)^2)$ and the classical Hardy space $H_p(^2)$ are introduced. We prove that certain means of the partial sums of the two-parameter Walsh-Fourier and trigonometric-Fourier series are uniformly bounded operators from ...
