Fitting formulae of the reduced-shear power spectrum for weak lensing

open access: yes, 2010
Context. Weak gravitational lensing is a powerful probe of large-scale structure and cosmology. Most commonly, second-order correlations of observed galaxy ellipticities are expressed as a projection of the matter power spectrum, corresponding to the ...

Detection of correlated galaxy ellipticities on CFHT data: first evidence for gravitational lensing by large-scale structures [PDF]

open access: yes, 2000
We report the detection of a significant (5.5 sigma) excess of correlations between galaxy ellipticities at scales ranging from 0.5 to 3.5 arc-minutes. This detection of a gravitational lensing signal by large-scale structure was made using a composite ...

Mathematical Relationship Between Particle Reynolds Number and Ripple Factor using Tapi River Data, India. [PDF]

open access: yesJournal of Systemics, Cybernetics and Informatics, 2011
The computation of bed load allows for the fact that only part of the shear stress is used for transport of sediments and some of the shear stress is wasted in overcoming the resistance due to bed forms therefore the total shear stress developed in the ...

Theoretical and Numerical Study on Stress Intensity Factors for FRP-Strengthened Steel Plates with Double-Edged Cracks

open access: yesSensors, 2018
This paper presents a theoretical and numerical study on the stress intensity factors for double-edged cracked steel plates strengthened with fiber reinforced polymer (FRP) plates. Based on the stress intensity factor solution for infinite center-cracked

Unitarity constraints on the ratio of shear viscosity to entropy density in higher derivative gravity [PDF]

open access: yes, 2010
We discuss corrections to the ratio of shear viscosity to entropy density $\eta/s$ in higher-derivative gravity theories. Generically, these theories contain ghost modes with Planck-scale masses.

Novel Layerwise Shear Correction Factors for Zigzag Theories of Circular Sandwich Plates with Functionally Graded Layers

open access: yesLatin American Journal of Solids and Structures
The available shear correction factors have mainly been proposed for single-layer rectangular plates with zero shear tractions and isotropic homogenous materials.

Application of Cfd-Based Correction Factors to Increase the Accuracy of Flow Curve Determination in A Couette Rheometer

open access: yesApplied Rheology, 2016
The measurement and the investigation of the errors in a Couette rheometer have been a topic of considerable interest in many rheometric studies. In the present study, a more accurate predictor-corrector method based on CFD and the analytical solution of

Galaxy-galaxy and galaxy-cluster lensing with the SDSS and FIRST surveys [PDF]

open access: yes, 2016
We perform a galaxy-galaxy lensing study by correlating the shapes of $\sim$2.7 $\times$ 10$^5$ galaxies selected from the VLA FIRST radio survey with the positions of $\sim$38.5 million SDSS galaxies, $\sim$132000 BCGs and $\sim$78000 SDSS galaxies that

Using Mason number to predict MR damper performance from limited test data

open access: yesAIP Advances, 2017
The Mason number can be used to produce a single master curve which relates MR fluid stress versus strain rate behavior across a wide range of shear rates, temperatures, and applied magnetic fields.
