Author:Theron, Bertus; El-Desouki, M; Aljekhedab, FMR; Alayed, MSI; Alsawad, MSDDate:Apr 2013A key imaging quality metric for an optical system (e.g. a camera or surveillance device) is its resolution. Methods to measure this, range from visual observation methods on resolution target charts, through more rigorous characterization, ...Read more
Author:Long, Craig S; Ramatlo, Dineo AM; Loveday, Philip WDate:Sep 2018In this paper, we present a comparison between two different methods for modelling the response of an elastic waveguide to a point force excitation.Read more
Author:Long, Craig S; Loveday, Philip W; Ramatlo, Dineo AM; Andhavarapu, EVDate:Sep 2018Numerical verification of a method to simulate piezoelectric transducers exciting infinite elastic waveguides is presented. The method, referred to as SAFE-3D, combines a 3D finite element (FE) model of a transducer with a 2D semi-analytical ...Read more
