GrainSizeTools: a Python script for grain size analysis and paleopiezometry based on grain size

Grain size, size-distribution and dislocation structure

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 size-distribution and dislocation structures. Physically based theoretical functions and their Fourier coefficients are available for both, the size...

Optimal Grain Size Computation for

In this paper, we present a method for overlapping communications on parallel computers for pipelined algorithms. We rst introduce a general theoretical model which leads to a generic computation scheme for the optimal packet size. Then, we use the OPIUM 3 library, which provides an easy-to-use and eecient way to compute, in the general case, this optimal packet size, on the column LU factoriza...

Material grain size and crack size influences on cleavage fracturing.

A review is given of the analogous dependence on reciprocal square root of grain size or crack size of fracture strength measurements reported for steel and other potentially brittle materials. The two dependencies have much in common. For onset of cleavage in steel, attention is focused on relationship of the essentially athermal fracture stress compared with a quite different viscoplastic yie...

Scheduling and grain size control

Locality and storage management considerations for fork-join parallelism lead to the loss of the important List Scheduling property. The worst case performance of the constrained scheduling policies, called PaH and ToS, is very bad: (nearly) all parallelism is lost. “Practical” performance, however, differs radically from worst case performance. The PaH and ToS policies perform on average withi...
