A vortex sheet based analytical model of the curled wake behind yawed wind turbines [PDF]
, 2021 Motivated by the need for compact descriptions of the evolution of non-classical wakes behind yawed wind turbines, we develop an analytical model to predict the shape of curled wakes. Interest in such modelling arises due to the potential of wake steering as a strategy for mitigating power reduction and unsteady loading of downstream turbines in wind ...

Origin of Multifractality in Solar Wind Turbulence: the Role of Current Sheets [PDF]
, 2023 In this work, a multifractal framework is proposed to investigate the effects of current sheets in solar wind turbulence. By using multifractal detrended fluctuation analysis coupled with surrogate methods and volatility, two solar wind magnetic field time series are investigated, one with current sheets and one without current sheets. Despite the lack

Hamiltonian perspective on generalized complex structure [PDF]
Commun.Math.Phys. 263 (2006) 711-722, 2005 In this note we clarify the relation between extended world-sheet supersymmetry and generalized complex structure. The analysis is based on the phase space description of a wide class of sigma models. We point out the natural isomorphism between the group of orthogonal automorphisms of the Courant bracket and the group of local canonical ...

Determination of Physical and Mechanical properties of Sugarcane Single-Bud Billet [PDF]
arXiv, 2022 Determining the physical and mechanical properties of sugarcane single-bud billets is a critical step in the mechanical structure design of a sugarcane planter. In this study, the TaiTang F66 cultivar sugarcane samples are analyzed. The moisture content of the billets is found to range from 63.78% to 77.72%, and the average density is 244.67 kg/m3. The

Wavelet analysis of magnetic turbulence in the Earth's plasma sheet [PDF]
Physics of Plasmas, 11, 1333, 2004, 2004 Recent studies provide evidence for the multi-scale nature of magnetic turbulence in the plasma sheet. Wavelet methods represent modern time series analysis techniques suitable for the description of statistical characteristics of multi-scale turbulence.

Role of Cold Storage in Rooting of Stem Cuttings: A Review [PDF]
, 2023 Cold storage is a strategy mainly used for ornamental cuttings for the purpose of prolonging production duration that provide the cuttings with the best condition at the time of planting. The results have been obtained from cold storage of carnations and chrysanthemums confirmed the fact that the herbaceous cuttings could be stored for about two months

Cotton Yield Prediction Using Random Forest [PDF]
arXiv, 2023 The cotton industry in the United States is committed to sustainable production practices that minimize water, land, and energy use while improving soil health and cotton output. Climate-smart agricultural technologies are being developed to boost yields while decreasing operating expenses. Crop yield prediction, on the other hand, is difficult because

Plasmoid Instability in Evolving Current Sheets and Onset of Fast Reconnection [PDF]
Astrophysical Journal, 849, 75 (2017), 2017 The scaling of plasmoid instability maximum linear growth rate with respect to Lundquist number $S$ in a Sweet-Parker current sheet, $\gamma_{max}\sim S^{1/4}$, indicates that at high $S$, the current sheet will break apart before it approaches the Sweet-Parker width.

On the consistency of score sheets of a round-robin football tournament [PDF]
arXiv, 2022 In this paper we introduce the submonoids $\mathscr{R}_n$, resp. $\mathscr{C}_n$, of the monoid $\mathscr{M}_n$ of ordered score sheets of a robin-round tournament played by $n$ teams for which the order is preserved after the leader team is disqualified, resp. all principal submatrices preserve the given ordering.

Hall Droplet Sheets in Holographic QCD [PDF]
, 2022 In single-flavor QCD, the low energy description of baryons as Skyrmions is not available. In this case, it has been proposed by Komargodski that baryons can be viewed as kinds of charged quantum Hall droplets, or "sheets". In this paper we propose a string theory description of the sheets in single-flavor holographic QCD, focusing on the Witten-Sakai ...
