The transverse magnetic (TM) radiation characteristics are investigated for a cylinder with N infinite axial slots of arbitrary opening size and location. The cylinder is a thin circular conductor and coated by an eccentric material. Fields are found by applying the boundary conditions to the cylindrical wave functions. The addition theorem of Bessel functions is used to obtain an infinite seri...
The recently proposed domain-free discretization (DFD) method is based on the Lagrange interpolation and polynomial-based differential quadrature (PDQ) method. In this article, the radial basis function (RBF) approximation is used in the DFD method as the interpolation scheme for function approximation, and the RBF-DQ method is applied to derivative approximation. The new variant of DFD method ...
Experimental study of high strength concrete-filled circular tubular columns under eccentric loading
Abstract—The transverse electric (TE) field patterns and characteristics are considered for a cylinder with N infinite axial slots of arbitrary opening size and position. The cylinder is a thin circular conductor and covered by an eccentric material. Radiations are determined by applying the boundary conditions to the cylindrical wave functions of the fields. The addition theorem of Bessel func...
We report a rare case of a limited chronic dissection of the ascending aorta that was accidentally discovered at operation performed for severe aortic stenosis and moderate to severe dilatation of the ascending aorta. Preoperative investigations such as transoesophageal echocardiography and cardiac catheterization missed the diagnosis of dissection. Intraoperative findings included a 3.5 cm ecc...
This study focuses on perforated pin fin convection heat transfer. study's goal is to see if fins may help transmit heat. Perforation diameter and hole count are evaluated each pin. The Nusselt number of pins 47% higher than solid pins, it increases with perforation count. Unperforated have a 19% lower pressure drop. Using circular holes as sinks, we examined forced There were perforations. The...
