We demonstrate the construction of diamond photonic crystal structures by the translation of a multi-beam interference pattern. Using phase shift of each beam, the double-exposed interference patterns can be aligned in the [111] direction for a face-centered cubic (FCC) and [210] direction for a body-centered cubic (BCC), respectively, producing diamond D from FCC and BCC-diamond like structure...

The Deformation T-Cup (DT-Cup) is a modified 6-8 multi-anvil apparatus capable of controlled strain-rate deformation experiments at pressures greater than 18 GPa. Controlled strain-rate deformation was enabled by replacing two of the eight cubic "second-stage" anvils with hexagonal cross section deformation anvils and modifying the "first-stage" wedges. However, with these modifications approxi...

Path planning is the key for unmanned aerial vehicle (UAV) to perform tasks efficiently, which needs quickly obtain optimal path in complex environment. To solve problem urban environment, an improved artificial bee colony algorithm based on multi-strategy synthesis (IABC) proposed generate appropriate UAV. The IABC hybrid mechanism of chaotic mapping and Pareto principle initialize population,...

Spontaneous figure reversal of ambiguous patterns was analyzed in humans by presenting “Necker-cube”-like, or “drum”-like figures having square or round shaped “front” and “rear” surfaces, and either large or small “depth”. The figures were perceived alternately according to one or the other of two possible mental orientation-interpretations. The subjects signalled the instant of subjective pat...

in this study, the optimal cropping patterns based on individual aims are presented and followed by a multi-objective cropping pattern with emphasize on the use of conservation tillage methods in darab region presented. individual goals consisted of maximizing gross margin and food secin this study, the optimal cropping patterns based on individual aims were presented and followed by using a mu...

Ontology mapping is the task of finding semantic relationships between entities (i.e. concept, attribute and relation) of two ontologies. In the existing literatures, many (semi-)automatic approaches have found considerable interest by combining several mapping strategies (namely multi-strategy mapping). However, experiments show that multi-strategy based mapping does not always outperform its ...

In this paper we study the existence of mild solutions for a class of first-order delay integrodifferential equations with nonlocal condition in a Banach space. The results are established by the application of the theory of resolvent operators, the contraction mapping principle and the Schaefer theorem. An example is presented in the end to show the applications of the obtained results. Mathem...

Single-phase perovskites were formed in the (1−x)Ba(Zn1/3Nb2/3)O3–(x)La(Zn2/3Nb1/3)O3 system for compositions with 0.0 ≤ x ≤ 0.6. Although the stability of the trigonal ‘‘1:2’’ ordered structure of the Ba(Zn1/3Nb2/3)O3 end member is very limited (0.0 ≤ x < 0.05), low levels of lanthanum induce a transformation to a cubic, ‘‘1:1’’ ordered structure that has a broad range of homogeneity (0.05 ≤ x...

In this paper, we propose a framework for modeling and deforming heterogeneous volumetric objects defined as point sets with attributes. We propose to use constructive hypervolume objects, where the function representation (FRep) is used as the basic model for both object geometry and attributes represented independently using realvalued scalar functions of point coordinates. While FRep directl...

and Applied Analysis 3 for some natural number n0. Moreover, if the second alternative holds, then i the sequence {Jnx} is convergent to a fixed point y∗ of J ; ii y∗ is the unique fixed point of J in the set Y : {y ∈ X | d J0x, y < ∞} and d y, y∗ ≤ 1/ 1 − L d y, Jy , for all , x, y ∈ Y . Following 30, 31 , we recall some basic facts concerning multi-normed spaces and some preliminary results. ...
