In this paper, the flow-induced oscillation of a prismatic body, viz., a square section cylinder (test cylinder) under interference conditions is analysed considering it as representing a typical building structure. The analysis is carried out using a data-mining tool called ‘Decision Tree’ mainly in view of assessing the safety of the structure (test cylinder) with respect to the vibratory amp...

Two conformal Finite-Di erence Time-Domain (FDTD) methods are considered, which eliminate the e ects of the stair-step approximation inherent at low points per wavelength (PPW). The rst, proposed by Jurgens et al. [IEEE Trans. Antennas Propagat., 40, 357{366, 1992], uses the contour path method. The second, proposed by Yee et al. [IEEE Trans. Antennas Propagat., 40, 1068{1075, 1992], uses overl...

The objective of the present work is to develop a numerical model to analyze melting solidification process considering the natural convection phenomena to an alloy metal in a square section. Physical medium is taken as incompressible Newtonian fluid with isotropy thermal properties where the heat is transferred by conduction and convection, including de thermal phase change phenomenon. The las...

Presented herein is a closed-form mathematical solution for the construction of an orthogonal cross section of intersecting cylinder surface geometry created from a single planar section. The geometry in its 3-dimensional state consists of the intersection of two cylindrical surfaces of equal radii which is bounded on all four sides by planes orthogonal to the primary cylinder axis. A multivari...
