Research ArticleOpen accessIn the abstractQuadrotor Obstacle Avoidance Based on Integral BacksteppingLianchuan Zhang, Young Baik Kim, Kil To ChongThis paper addressed obstacle avoidance problem of a quadrotor in outdoor environment. Path planning was finished by employing classical Dijkstra algorithm and the controller of the quadrotor adopted integral backstepping method. In order to get a smooth trajectory with time optimal and acceleration constraints properties, quantic polynomials were utilized to generate trajectory file. The scheme is particularly practical and useful … …American Journal of Applied Sciences, Vol. 13, Issue 7 · 27 Jul 2016 · 6,981 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Modeling of Flow in a Horizontal Sand FilterRuth Mossad, Hal AralProblem statement: Horizontal sand filters may offer some advantage over vertical sand filters as they could be used for in-line treatment of wastewaters. Horizontal pipelines of tens and if not hundreds of meters length, filled with ordinary sand or permeable reactive media such as activated carbon or natural zeolite or iron filings, may be used to remove impurities from mine … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,502 accessesView PDFCite
Research ArticleOpen accessIn the abstractPressure-sensitivity Effects on Toughness Measurements of Compact Tension Specimens for Strain-hardening SolidsAbdulhamid A. Al-AbduljabbarThe path-independent J-integral is used as a fracture prediction criterion for loading beyond the elastic limit as Linear Elastic Fracture Mechanics (LEFM) cannot be applied. While J was originally defined from an energy perspective, it was demonstrated that it could be inferred from load-displacement diagrams. Therefore, the Compact Tension (CT) specimen testing is used to compute J for materials. In … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,657 accessesView PDFCite
