Electromagnetic (EM) wave scattering by many parallel infinite cylinders is studied asymptotically as a → 0, where a is the radius of the cylinders. It is assumed that the centers of the cylinders x̂m are distributed so that N (∆) = ln( 1 a ) ∫ ∆ N(x)dx[1 + o(1)], where N (∆) is the number of points x̂m = (xm1, xm2) in an arbitrary open subset of the plane xOy, the axes of cylinders are parallel ...

This paper studies constructing advanced effective materials using arrays of circular radially-anisotropic (RA) cylinders. Homogenization of such cylinders is considered in an electrodynamic case based on Mie scattering theory. The homogenization procedure consists of two steps. First, we present an effectively isotropic model for individual cylinders, and second, we discuss the modeling of a l...

Flow and flow-induced vibration of a square array of cylinders are investigated by two-dimensional numerical simulations. Flow past 36 cylinders in an inline arranged square array and 33 cylinders in a staggered arranged square array is firstly simulated, for Re=100 and the spacing ratios of L/D=1.5, 2, 3, 4, 5. Only one vortex street is observed in the wake of the cylinder array when the spaci...

in this paper, stress and displacement fields of functionally graded (fg) nanocomposite cylinders reinforced by carbon nanotubes (cnts) subjected to internal pressure and in thermal environment are investigated by finite element method. the nanocomposite cylinders are combinations of single-walled carbon nanotubes (swcnts) and isotropic matrix. material properties are estimated by a micro mecha...

A two-dimensional numerical study of flow across rows of identical square cylinders arranged in staggered fashion is carried out. This study will unreveal complex flow physics depending upon the Reynolds number (Re) and gap spacing (g) between the cylinders. The combined effect of Reynolds number and gap spacing on the flow physics around staggered rows of cylinders are numerically studied for ...

Original scientific paper One of the most important features in lithography is the stability of the printing plates during the printing process. The offset printing plates are mainly built of aluminium foil which is processed to obtain surface structure needed for printing process requirements. Printing plate is during printing process under mechanical and chemical influence of the machine part...

BACKGROUND Although tissue microarray (TMA) studies of histopathologic material have been frequently reported in studies of malignant diseases, the question of sample size (i.e., the diameter and the number of tissue cylinders investigated) has been rarely discussed. This study addresses the methodologic question of sample size in a variety of tumor types. MATERIAL AND METHODS Material from 2...

Inkjet printing is widely used in functional product manufacturing. Performing a printing task requires communication and synchronization among multiple subsystems (e.g. motion and drop ejection), which introduces complexity in the overall printing system. A user interface has been developed, which enables users to input printing parameters and patterns for printing functional materials. The in...

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...
