Cone photoreceptors in teleost fish are organized in precise, crystalline arrays in the epithelial plane of the retina. In zebrafish, four distinct morphological/spectral cone types occupy specific, invariant positions within a regular lattice. The cone lattice is aligned orthogonal and parallel to circumference of the retinal hemisphere: it emerges as cones generated in a germinal zone at the ...

Metal spinning as a kind of manufacturing process has capability to shape hollow components. In present work shear spinning process is used to formplates into conical shapes. Moreover, the aim of this research is to demonstrate the impact of the process parameters (i.e. feeding rate and spindle speed) on wall thickness. This approachwas done by experimental and finite elements method. The resul...

Acoustic spin has been recently explored for many applications. In particular, transverse acoustic was demonstrated inhomogeneous fields. this Letter, we show the emergence of and torque in rotating objects same physical properties as surrounding, to single out effects purely due rotation. The spinning a cylindrical column air or water medium possesses intrinsic angular momentum, study force it...

in this article using comparative multi-purpose algorithm of pso, optimum capacity of new resources and their spinning storage is defined. spinning reserve requirements and optimized to maximize profit per unit is determined according to uncertainty. in fact by increasing the level of cost reservation, power supply increases but penalty of blackout decreases. in this paper in has been tried to ...

For the symmetric cone complementarity problem, we show that each stationary point of the unconstrained minimization reformulation based on the FischerBurmeister merit function is a solution to the problem, provided that the gradient operators of the mappings involved in the problem satisfy column monotonicity or have the Cartesian P0-property. These results answer the open question proposed in...

ABSTRACT Recent observations have shown that a large portion of the mid-infrared (MIR) spectrum active galactic nuclei (AGNs) stems from polar regions. In this paper, we investigate effects gas on X-ray AGNs using ray-tracing simulations. Two geometries for are considered, (1) hollow cone corresponding to best-fitting MIR model and (2) filled cone, both with varying column densities (ranging 10...

In this paper the vibration of a spinning cylindrical shell made of functional graded material is investigated. After a brief introduction of FG materials, by employing higher order theory for shell deformation, constitutive relationships are derived. Next, governing differential equation of spinning cylindrical shell is obtained through utilizing energy method and Hamilton’s principle. Making ...
