Differential image motion in the short exposure regime

, 2011
Whole atmosphere seeing \beta_0 is the most important parameter in site testing measurements. Estimation of the seeing from a variance of differential image motion is always biased by a non-zero DIMM exposure, which results in a wind smoothing.

Searching for galaxy clusters using the aperture mass statistics in 50 VLT fields

, 2005
Application of the aperture mass (Map-) statistics provides a weak lensing method for the detection of cluster-sized dark matter halos. We present a new aperture filter function and maximise the effectiveness of the Map-statistics to detect cluster-sized

Bending and free vibration analysis of thick isotropic plates by using exponential shear deformation theory

Applied and Computational Mechanics, 2012
This paper presents a variationally consistent an exponential shear deformation theory for the bi-directional bending and free vibration analysis of thick plates. The theory presented herein is built upon the classical plate theory.

A weak lensing analysis of the Abell 383 cluster

, 2011
In this paper we use deep CFHT and SUBARU $uBVRIz$ archival images of the Abell 383 cluster (z=0.187) to estimate its mass by weak lensing. To this end, we first use simulated images to check the accuracy provided by our KSB pipeline.

Parametric Sensitivity of Shear Correction Factors for Multiwall Corrugated Structures

Materials
Transverse shear deformation plays a non-negligible role in lightweight periodic-core structures and motivates the use of shear-corrected reduced-order plate and beam models. However, the shear correction factor ks is often treated as a constant despite its strong dependence on cross-sectional heterogeneity and geometry. This work quantifies the global

QCD Shear Viscosity at (almost) NLO

, 2018
We compute the shear viscosity of QCD with matter, including almost all next-to-leading order corrections -- that is, corrections suppressed by one power of $g$ relative to leading order. We argue that the still missing terms are small.

Comparison of various refined beam theories for the bending and free vibration analysis of thick beams

Applied and Computational Mechanics, 2011
In this paper, unified shear deformation theory is used to analyze simply supported thick isotropic beams for the transverse displacement, axial bending stress, transverse shear stress and natural frequencies.

A refined shear deformation theory for flexure of thick beams

Latin American Journal of Solids and Structures
A Hyperbolic Shear Deformation Theory (HPSDT) taking into account transverse shear deformation effects, is used for the static flexure analysis of thick isotropic beams. The displacement field of the theory contains two variables.
