Advances in martensitic transformations in Cu-based shape memory alloys achieved by in situ neutron and synchrotron X-ray diffraction methods [PDF]

open access: yes, 2012
This article deals with the application of several X-ray and neutron diffraction methods to investigate the mechanics of a stress induced martensitic transformation in Cu-based shape memory alloy polycrystals. It puts experimental results obtained by two

Towards Realistic Simulations of Macromolecules Irradiated under the Conditions of Coherent Diffraction Imaging with an X-ray Free-Electron Laser

open access: yesPhotonics, 2015
Biological samples are highly radiation sensitive. The rapid progress of their radiation damage prevents accurate structure determination of single macromolecular assemblies in standard diffraction experiments. However, computer simulations of the damage

THE APPLICATION OF MESHLESS CYLINDER CONTROL SURFACE IN RANKINE-KELVIN HYBRID METHOD

open access: yesBrodogradnja, 2016
The solution of the three-dimensional seakeeping problem with forward speed in the frequency domain still has some well-known problems. In this paper, a Rankine-Kelvin hybrid method benefiting the merits of both the Rankine source and Kelvin source is ...

On the complete radiation-diffraction problem and wave-drift damping of marine bodies in the yaw mode of motion [PDF]

open access: yesJournal of Fluid Mechanics, 1998
The coupled radiation-diffraction problem due to a floating body with slow (time-dependent) rotation about the vertical axis in incoming waves is studied by means of potential theory. The water depth may be finite. First, the radiation problem is described.
