Cosmic shear analysis of archival HST/ACS data: I. Comparison of early ACS pure parallel data to the HST/GEMS Survey [PDF]

, 2006
This is the first paper of a series describing our measurement of weak lensing by large-scale structure using archival observations from the Advanced Camera for Surveys (ACS) on board the Hubble Space Telescope (HST).

Improving Large Wind Turbine Power Curve by Integrating Lidar-Measured Multiple Wind Parameters: A Coastal Case Study

Energies
A new power curve that is suitable for describing large wind turbines with long blades is proposed in this study. Improving the accuracy of power generation curves for large wind turbines not only involves current wind turbine development trends but also

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 ...

Primordial Non-Gaussianity and the Statistics of Weak Lensing and other Projected Density Fields [PDF]

, 2011
Estimators for weak lensing observables such as shear and convergence generally have non-linear corrections, which, in principle, make weak lensing power spectra sensitive to primordial non-Gaussianity.

Cosmological constraints from the convergence 1-point probability distribution

, 2016
We examine the cosmological information available from the 1-point probability distribution (PDF) of the weak-lensing convergence field, utilizing fast L-PICOLA simulations and a Fisher analysis.

Bending, buckling and free vibration responses of hyperbolic shear deformable FGM beams [PDF]

Mechanics of Advanced Composite Structures, 2018
This study investigated bending, buckling, and free vibration responses of hyperbolic shear deformable functionally graded (FG) higher order beams. The material properties of FG beams are varied through thickness according to power law distribution; here,

Statistical and Systematic Errors in Measurement of Weak-Lensing Minkowski Functionals: Application to Canada-France-Hawaii Lensing Survey

, 2014
The measurement of cosmic shear using weak gravitational lensing is a challenging task that involves a number of complicated procedures. We study in detail the systematic errors in the measurement of weak lensing Minkowski Functionals (MFs). Specifically,

An adaptive preconditioner for steady incompressible flows [PDF]

, 2016
This paper describes an adaptive preconditioner for numerical continuation of incompressible Navier--Stokes flows. The preconditioner maps the identity (no preconditioner) to the Stokes preconditioner (preconditioning by Laplacian) through a continuous ...

Vibration controlof tapered magnetostrictive plate considering shear correction factor [PDF]

Scientia Iranica, 2016
In this research, dynamic response of tapered plate made of MsM (magnetostrictive material) is studied for the first time. First order shear deformation theory (FSDT) is used to derive the governing equations of tapered MsP (magnetostrictive plate) while the thickness varies linearly.
