Edge Detection on Hexagonal Structure [PDF]
Gradient-based edge detection is a straightforward method to identify the edge points in the original grey-level image. It is intuitive that in the human vision system the edge points always appear where the grey-level value is greatly changed.

Hexagonal Structure of Baby Skyrmion Lattices [PDF]
We study the zero-temperature crystalline structure of baby Skyrmions by applying a full-field numerical minimization algorithm to baby Skyrmions placed inside different parallelogramic unit-cells and imposing periodic boundary conditions.

Hexagonal structure for intelligent vision [PDF]
Using hexagonal grids to represent digital images have been studied for more than 40 years. Increased processing capabilities of graphic devices and recent improvements in CCD technology have made hexagonal sampling attractive for practical applications ...

Basic transformations on virtual hexagonal structure [PDF]
Hexagonal structure is different from the traditional square structure for image representation. The geometrical arrangement of pixels on hexagonal structure can be described in terms of a hexagonal grid.

Structural domain walls in polar hexagonal manganites [PDF]
We present a microscopic first-principles study of the neutral structural domain walls (DWs) in the multiferroic hexagonal manganites, which have been shown to exhibit cross-couplings between ferroelectricity and struc- tural antiphase. We find that, in contradiction with previously proposed models, the interlocked antiphase- ferroelectric domain walls

Natural hyperbolicity in layered hexagonal crystal structures [PDF]
Discovering the physical requirements for meeting the indefinite permittivity in natural material as well as proposing a new natural hyperbolic media offer a possible route to significantly improve our knowledge and ability to confine and controlling light in optoelectronic devices.

Embedded atoms in a crystalline hexagonal structure
As part of the work, the hexagonal structure of B19 type metals as hydrogen sorbents will be considered. That is, crystal lattices are considered, where atoms of impurities (hydrogen) are introduced into the interstices of the metal.

Tuning the Magnetic Ordering Temperature of Hexagonal Ferrites by Structural Distortion Control [PDF]
To tune the magnetic properties of hexagonal ferrites, a family of magnetoelectric multiferroic materials, by atomic-scale structural engineering, we studied the effect of structural distortion on the magnetic ordering temperature (TN).

Structure of hexagonal ζ´-AlMnCo
Abstract The structure of ζ´-Al80Mn16Co4 was analyzed using single-crystal X-ray diffraction. The diffraction pattern indicated that the ζ´-AlMnCo phase has a hexagonal unit cell with a space group P63/m, a = 30.5173(5) Å, c = 12.4742(2) Å, and the a-axis is
