Calculation of radiation field integrals for higher-order basis functions in conical thin wire MoM formulation

Author: Lysko, Albert A Date: Jul 2008 An efficient method of integration for far field calculations is derived. The method applies to the integrals arising from calculation of far field pattern with higher-order polynomial basis functions and moment method. The integral under ... Read more
Characterisation of submerged arc welding process using infrared imaging technique

Author: Zondi, MC ; Tekane, Yanga C ; Magidimisha, Edwin ; Wium, Elsmari ; Gopal, Ajith K ; Bemont, C Date: Sep 2017 Infrared (IR) thermography is a technique used to measure temperature distribution of heat generation in manufacturing processes such as welding. IR thermography is a non-destructive and non-contact method, which makes it favoured for the arc ... Read more
Linear elastic analysis of pavement structure under non-circular loading

Author: Maina, JW ; Ozawa, Y ; Matsui, K Date: Oct 2012 Conventional methods for road and airport pavement analyses, such as BISAR and GAMES, were developed based on a cylindrical coordinate system. Because of the loading symmetry due to the assumption that a circular uniformly distributed load ... Read more
Numerical analysis of guided wave transmission through a long defect in a rail rack

Author: Loveday, PW ; Long, Craig S Date: Nov 2022 Guided wave ultrasound has been used to continuously monitor welded rail track by transmitting guided wave ultrasound between alternate transmit and receive stations along the rail. A section of rail was encountered where transmission was not ... Read more
On advanced variational formulation of the method of lines and its application to the wave propagation problems

Author: Shatalov, M Date: Sep 2012 The method of lines is a simple and reliable method of numerical analysis of parabolic and hyperbolic problems of mathematical physics. By means of this method mixed initial-boundary problems described by partial differential equations are ... Read more
