Weak lensing power spectra for precision cosmology: Multiple-deflection, reduced shear and lensing bias corrections [PDF]
, 2010 It is usually assumed that the ellipticity power spectrum measured in weak lensing observations can be expressed as an integral over the underlying matter power spectrum. This is true at second order in the gravitational potential. We extend the standard

International Journal of Mechanical and Materials Engineering, 2016 The first-order shear deformation theory (FSDT) for plates requires a shear correction factor due to the assumption of constant shear strain and shear stress across the thickness; hence, the shear correction factor strongly influences the accuracy of the

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

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

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

Thermal Deformation of Antisymmetric Angle-ply Laminated Plate Strips in Cylindrical Bending
Journal of King Saud University: Engineering Sciences, 2002 Exact analytical solutions for the thermal deformations of antisymmetric angle-ply laminated plate strips in cylindrical bending are developed. The state variable technique in conjunction with Jordan canonical form is used to obtain these solutions for ...

Measurement and Calibration of Noise Bias in Weak Lensing Galaxy Shape Estimation [PDF]
, 2012 Weak gravitational lensing has the potential to constrain cosmological parameters to high precision. However, as shown by the Shear TEsting Programmes (STEP) and GRavitational lEnsing Accuracy Testing (GREAT) Challenges, measuring galaxy shears is a ...
