Nucleation in an aluminium tricrystal cold rolled along its columnar direction, to 40% thickness reduction, is studied. This experimental configuration was used obtain the same deformation microstructure through sample length, which made it possible cut into several slices of similar microstructures and use these differently. Some served analyse others annealing microstructure. developed only o...

We discuss the relationship between the local-global map hypothesis of Vl and Spiral Harmonic Mosaic algebra, illustrated with a simple model of Vl. We describe long-range patchy connections by assuming they share a symmetry with the local connectivity. We also show that the elongated pattems of connectivity, implicated in the orientation response property, can be related to the patterns of con...

Reliable EBSD mapping of 90 degree domains in a tetragonal ferroelectric perovskite has been achieved for the first time, together with reliable automated orientation determination from TEM-Kikuchi patterns. This has been used to determine misorientation angles at 90 degree domain boundaries and thus local c/a ratios. The sources of orientation noise/error and their effects on the misorientatio...

aim: considering the fundamental role of parents' function and family dynamics including the importance role of family communication pattern on preventing early-onset substance use in children, the present study aimed to determine the correlation between family communication pattern and mothers' preventive behavioral intention regarding preventing early-onset substance use in children...

The exploration of a connected graph by multiple mobile agents has been previously studied under different conditions. A fundamental coordination problem in this context is the gathering of all agents at a single node, called the Rendezvous problem. To allow deterministic exploration, it is usually assumed that the edges incident to a node are locally ordered according to a fixed function calle...

Image search systems based on local descriptors typically achieve orientation invariance by aligning the patches on their dominant orientations. Albeit successful, this choice introduces too much invariance because it does not guarantee that the patches are rotated consistently. This paper introduces an aggregation strategy of local descriptors that achieves this covariance property by jointly ...

Fingerprint classification provides an important indexing mechanism in a fingerprint database. Accurate and consistent classification can greatly reduce fingerprint-matching time and computational complexity for a large database as the input fingerprint needs to be matched only with a subset of the fingerprint database. Classification into six major categories (whorl, right loop, left loop, twi...

The progress of the studies on the orientation of galaxies in the Local Supercluster (LSC) is reviewed and a summary of recent results is given. Following a brief introduction of the LSC, we describe the results of early studies based on two-dimensional analysis, which were mostly not conclusive. We describe next the three-dimensional analysis, which is used widely today. Difficulties and syste...
