Sentence examples for Perfect periodicity from inspiring English sources
In this paper, we propose a new numerical multiscale homogenization method for nearly periodic structures, where perfect periodicity is disturbed due to unintended geometrical imperfections.
Directional ripple patterns with perfect periodicity can be formed on PC surfaces by scratching zigzag patterns with an AFM tip.
Fast techniques are also constructed for problems involving lattices with inclusions and local deviations from perfect periodicity.
The perfect periodicity demonstrated in the picture indicated that the response to the visible light illumination is steady and the time required for the response is equal.
The effects of deviations from perfect periodicity are considered, particularly with reference to the dramatic changes in mode shapes that sometimes occur.
The complexity of the methods described is O Nboundary + Nsource + Ninc) where Nboundary is the number of nodes on the boundary of the domain, Nsource is the number of nodes subjected to body loads, and Ninc is the number of nodes that deviate from perfect periodicity.
Finally, a 3-storey near mono-coupled periodic experimental building is used to verify the actual application of the proposed method in consideration of the influence of measurement noise and non-perfect periodicity of actual engineering structures.
For the purposes of this paper we define perfect p-periodicity in a fragment of length N as (2) where n0 is the position of the first dinucleotide(s) of interest and δ[ n] is the Kronecker delta.
Correlation based methods have been applied widely in sequence analysis, are attractive since they operate directly on the symbolic sequence, are equally spaced in period (referred to here as 'linear-period') and are relatively tolerant of both eroded perfect and approximate periodicity.
There, images are acquired in a geometry identical to ours (with a common A-scan) after which each frame in a sequence at a given angle is assigned a new time stamp (based on an algorithm that assumes perfect, yet unknown, periodicity in the sequence).
The recent approaches, which addressed full periodicity, partial periodicity, perfect and imperfect periodicity [7], and asynchronous periodicity [18] are all based on fixed size and adjacent time units and fixed length of discovered patterns.
