Wind turbine load validation in wakes using wind field reconstruction techniques and nacelle lidar wind retrievals [PDF]

open access: yesWind Energy Science, 2021
This study proposes two methodologies for improving the accuracy of wind turbine load assessment under wake conditions by combining nacelle-mounted lidar measurements with wake wind field reconstruction techniques.

Some Properties of Extended Euler’s Function and Extended Dedekind’s Function

open access: yesMathematics, 2020
In this paper, we find some properties of Euler’s function and Dedekind’s function. We also generalize these results, from an algebraic point of view, for extended Euler’s function and extended Dedekind’s function, in algebraic number fields ...

Reducing pesticides without organic certification? Potentials and limits of an intermediate form of agricultural production

open access: yesCogent Food & Agriculture, 2023
A growing number of farmers’ cooperatives cultivate crops without chemical pesticides, but also without organic certification. How does this intermediate form of agriculture between conventional and organic production function?

Class numbers of cyclotomic function fields [PDF]

open access: yesMathematics of Computation, 1986
Using results of Galovich and Rosen the plus and minus factors for the class number of the cyclotomic function field associated with irreducibles of degree three and four over the field with three elements are computed. As a consequence it is shown that the analogue to a result of Kummer on the p

The Chebotarev density theorem for function fields-Incomplete intervals

open access: yes, 2021
We prove a Polya-Vinogradov type variation of the Chebotarev density theorem for function fields over finite fields valid for "incomplete intervals" I subset of F-p, provided (p(1/2) log p)/|I| = o(1). Applications include density results for irreducible

Testing the Beta-Lognormal Model in Amazonian Rainfall Fields Using the Generalized Space q-Entropy

open access: yesEntropy, 2017
We study spatial scaling and complexity properties of Amazonian radar rainfall fields using the Beta-Lognormal Model (BL-Model) with the aim to characterize and model the process at a broad range of spatial scales.

Holographic topological defects in a ring: role of diverse boundary conditions

open access: yesJournal of High Energy Physics, 2022
We investigate the formation of topological defects in the course of a dynamical phase transition with different boundary conditions in a ring from AdS/CFT correspondence.

Investigating the Number of Monte Carlo Simulations for Statistically Stationary Model Outputs

open access: yesAxioms, 2023
The number of random fields required to capture the spatial variability of soil properties and their impact on the performance of geotechnical systems is often varied.
