Overlapping Unit Cells in 3d Quasicrystal Structure
A 3-dimensional quasiperiodic lattice with overlapping unit cells is constructed using grid and projection methods pioneered by de Bruijn. Using Kronecker’s theorem the frequencies of all possible types of overlapping are found.
متن کامل3D structure from video streams with partially overlapping images
The majority of methods available to recover 3D structure from video assume that a set of feature points are tracked across a large number of frames. This is not always possible in real videos because the images overlap only partially, due to the occlusion and the limited field of view. This paper describes a new method to recover 3D structure from videos with partially overlapping views. The w...
متن کاملSymmetry Structure of the Elser-sloane Quasicrystal
T . This can now be used to find all patterns in LI(P) with special symmetries (relative to the origin) which is a standard procedure in crystallography. For repetitive, but non-crystallographic P , however, the LI-class has a much richer structure and contains uncountably many (20) translation classes. It is thus much more difficult to classify the complete symmetry structure of such classes, ...
متن کاملStructure Analysis of a Hyper-Complex Approximant to Icosahedral Quasicrystal using 3D Electron Diffraction Tomography
Analyzing the crystal structure of approximants is of vital importance in deriving structural information of building units (or basic clusters) and their arrangements toward icosahedral quasicrystals (IQCs). The acquired knowledge is essential in performing a hyper-space modeling, which is the only feasible way of today to elucidate the structural details of IQC’s. Since approximants are period...
متن کاملDirect 3D imaging of Al70.4Pd21Mn8.6 quasicrystal local atomic structure by X-ray holography
Inverse x-ray fluorescence holography was used to explore the local atomic order of a nearly perfect quasicrystal with composition Al70. 4Pd21Mn8.6. We have demonstrated the possibility of direct 3D imaging of the atomic decoration in a quasicrystal. We have obtained the average 3D environment of selected coordination shells around the Mn atoms. These results open the way to obtaining further a...
