Grain size, size-distribution and dislocation structure from diffraction peak profile analysis

, 2002
Diffraction peak profile analysis (or Line Profile Analysis, LPA) has recently been developed to such an extent that it can be applied as a powerful method for the characterization of microstructures of crystalline materials in terms of crystallite ...

LIQUID LAYERS MOTION INVESTIGATION

Advanced Engineering Research, 2011
The diffraction motion of two layers of the incompressible heavy liquid around the vertical circular support column is investigated. The hard cover approaching is used to distinguish internal wave alone. The research data are extended to the utmost scope

Leaky Wave Modes and Edge Waves in Land-Fast Ice Split by Parallel Cracks

Journal of Marine Science and Engineering
In this paper we consider flexural-gravity waves propagating in a layer of water of constant depth limited by a vertical wall simulating a straight coastline. The water surface is covered with an elastic ice sheet of constant thickness.

A study of breakwater gap wave diffraction using close range photogrammetry and finite and infinite elements.

, 1984
In this thesis the diffraction of water waves passing through a gap in a breakwater is investigated experimentally, using close range photogrammetry, and numerically, using finite and infinite elements.

Lattice parameter measurement using Le Bail versus structural (Rietveld) refinement: A caution for complex, low symmetry systems

, 2005
The measurement of lattice parameters using the Le Bail method was shown to be inappropriate for a complex, low symmetry, structure, even with high resolution synchrotron diffraction data.

Green Scalar Function Method for Analyzing Dielectric Media

Applied Sciences
In this work we present a formalism based on scalar Green’s functions to deal with electromagnetic scattering problems. Although the formulations of the Mie theory and Born approximations in terms of electromagnetic scattering are well known and relevant,

Demo 23-04 Thin Wire Diffraction

, 2001
Light from a laser is diffracted by a wire of diameter 0.22 mm. For comparison the laser beam is first shown without the wire and then with the wire in place.

Finite and infinite element method applied to water wave diffraction problems [PDF]

, 1999
In this work, three types of infinite elements are developed to solve the problem of linear water wave diffraction by objects in a 2D unbounded domain. The infinite elements, which model the far field wave potential stretching to infinity, are coupled to
