Shannon Entropy-Based Wavelet Transform Method for Autonomous Coherent Structure Identification in Fluid Flow Field Data

open access: yesEntropy, 2015
The coherent secondary flow structures (i.e., swirling motions) in a curved artery model possess a variety of spatio-temporal morphologies and can be encoded over an infinitely-wide range of wavelet scales.

Comparison of compressible and incompressible numerical methods in simulation of a cavitating jet through a poppet valve

open access: yesEngineering Applications of Computational Fluid Mechanics, 2019
The regime of compressible flow generally refers to the super/subsonic case. However, several remarkable cases with low Mach number could not be appropriately described with the incompressible method.

The Study of Turbulent Fluctuation Characteristics in a Small Rotary Engine with a Peripheral Port Based on the Improved Delayed Detached Eddy Simulation Shear-Stress Transport (IDDES-SST) Method

open access: yesEnergies, 2018
In this paper, an improved delayed detached eddy simulation method combined with shear-stress transport (SST) model was used to study the three-dimensional turbulent characteristics in a small rotary engine with a peripheral port.

The Compression of the Heliospheric Magnetic Structure by Interplanetary Shocks: Is the Structure at 1AU a Manifestation of Solar-Wind Turbulence or Is It Fossil Structure From the Sun?

open access: yesFrontiers in Astronomy and Space Sciences, 2020
As a test of the action of MHD turbulence in the solar wind, the compression of the heliospheric magnetic structure at 1AU by 109 interplanetary shocks is examined.

Influence of Reynolds number on coherent structure, flow transition, and evolution of the plane jet

open access: yesJournal of Fluid Science and Technology, 2014
In the present study, the flow characteristics of a spatially evolving plane jet are investigated, focusing on the dynamics of coherent structure (CS), flow transition, and evolution.

Coherent Semantic Attention for Image Inpainting [PDF]

open access: yesIEEE International Conference on Computer Vision, 2019
The latest deep learning-based approaches have shown promising results for the challenging task of inpainting missing regions of an image. However, the existing methods often generate contents with blurry textures and distorted structures due to the ...

Coherence for bicategorical cartesian closed structure

open access: yesMathematical Structures in Computer Science, 2021
AbstractWe prove a strictification theorem for cartesian closed bicategories. First, we adapt Power’s proof of coherence for bicategories with finite bilimits to show that every bicategory with bicategorical cartesian closed structure is biequivalent to a 2-category with 2-categorical cartesian closed structure.

Rigorous coherent-structure theory for falling liquid films: Viscous dispersion effects on bound-state formation and self-organization [PDF]

open access: yes, 2010
We examine the interaction of two-dimensional solitary pulses on falling liquid films. We make use of the second-order model derived by Ruyer-Quil and Manneville [Eur. Phys. J. B 6, 277 (1998); Eur. Phys. J. B 15, 357 (2000); Phys. Fluids 14, 170 (2002)]

On a Novel Methodology for South Atlantic Convergence Zone Events Classification Using a Multimodal Convolutional Neural Network

open access: yesIEEE Access
The precipitation in the Southwest and Midwest regions of Brazil is strongly influenced by the South Atlantic Convergence Zone (SACZ). However, predicting and detecting this phenomenon is a difficult task.
