Author:Ackermann, ER; Grobler, TL; Kleynhans, W; Olivier, JC; Salmon, BP; Van Zyl, AJDate:Sep 2012We use Cavalieri’s principle to develop a novel integration technique which we call Cavalieri integration. Cavalieri integrals differ from Riemann integrals in that non-rectangular integration strips are used. In this way we can use single ...Read more
Author:Glaser, Daniel; Polese, CDate:Sep 2017Laser shock peening (LSP) technology is a laserinduced shock process implemented as a surface enhancement technique to introduce beneficial compressive residual stresses into metallic components. The process employs water to confine and enhance ...Read more
Author:Auret, JG; Damm, OFRA; Wright, GJ; Robinson, FPADate:Dec 1993Cavitation erosion tests were carried out in tap water on aluminium and copper samples in a rotating disk cavitations test apparatus, to study the effect of water temperature on cavitation dynamics and cavitation erosion. A shift in the ...Read more
Author:Mokhena, Teboho C; John, Maya JDate:Feb 2020This review describes the recent advances in the production and application of cellulose nanomaterials.
