We theoretically characterized the diffraction properties of both closed-packed and non-closed-packed crystalline colloidal array (CCA) photonic crystals. A general theory based on single-scattering kinematic approach was developed and used to calculate the diffraction efficiency of CCA of different sphere diameters at different incident light angles. Our theory explicitly relates the scatterin...

Finite-element analysis is used to study the thermal deformation of a multilayer mirror due heat load from undulator beam at low-emittance synchrotron source, specifically ESRF-EBS upgrade beamline EBSL-2. The energy bandwidth double-multilayer monochromator larger than that relevant harmonic, such considerable portion reflected. Consequently, absorbed power non-uniformly distributed on surface...

(1) Each pair of points can be joined by one and only one straight line segment. (2) Any straight line segment can be indefinitely extended in either direction. (3) There is exactly one circle of any given radius with any given center. (4) All right angles are congruent to one another. (5) If a straight line falling on two straight lines makes the interior angles on the same side less than two ...

it has been reported previously that modulatory effects of pleasant and unpleasant slides on the human acoustic reflex are observed only if startle probes are presented to the left ear or with binaural presentation. the present study examined the effects of the left and the right ear stimulation on modulated startle reflex (as indexed by eyeblink component, measured at the right eye) employing ...

In this paper, mechanical buckling analysis of composite annular sector plates with bean shape cut out is studied. Composite material sector plate made of Glass-Epoxy and Graphite-Epoxy with eight layers with same thickness but different fiber angles for each layer. Mechanical loading to form of uniform pressure loading in radial, environmental and biaxial directions is assumed. The method used...
