Research ArticleOpen accessIn the keywordsArtificial Neural Networks Based Red Palm Weevil (Rynchophorus Ferrugineous, Olivier) Recognition SystemSaleh Mufleh Al-Saqer, Ghulam Mubashar HassanProblem statement: The most dangerous insect for the existence of palm trees in entire world is Red Palm Weevil (scientifically named as Rynchophorus Ferrugineous, Oliveir). The proposed research is conducted to develop an identification system for Automated Wireless Red Palm Weevil Detection and exterminated. The core idea of the proposed research is to develop software that can utilize image processing … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 9,190 accessesView PDF Cite

Research ArticleOpen accessIn the author namesRainfall Depth-Duration-Frequency Relationships for South Carolina, North Carolina, and GeorgiaJ. P. Raiford, N.M. Aziz, A.A. Khan, D.N. PowellThe depth-duration-frequency curves and isopluvial maps for the region encompassing South Carolina, North Carolina, and Georgia were developed using the available rainfall data. The aim was to update the existing intensity-duration-frequency curves in the region and obtain these curves at ungauged sites throughout the region using the newly developed rainfall frequency analysis techniques. A total of 17 durations ranging from … …American Journal of Environmental Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,330 accessesView PDF Cite

Research ArticleOpen accessIn the abstractConjugate Gradient ‎Method: A Developed Version to Resolve Unconstrained Optimization ProblemsAhmad Alhawarat, Nguyen-Thoi Trung, Zabidin SallehOne of the important methods that are widely utilized to resolve ‎unconstrained ‎optimization problems is the Conjugate Gradient (CG) method. This paper aims to propose a new version of the CG method on the basis of Weak Wolfe-Powell (WWP) line search. The assumption is bounded below optimization problems with the Lipschitz continuous gradient. The new parameter obtains global convergence properties … …Journal of Computer Science, Vol. 16, Issue 9 · 18 Sep 2020 · 6,894 accessesView PDF Cite

EditorialOpen accessIn the abstractWhere the Future is Being Made TodayMark A. Brown, Joachim Storsberg, Christian SchmidtGrowing up, I was fascinated by The Muppet Show and the adventures of Dr. Bunsen Honeydew and his assistant Beaker. Apparently, my feelings were not unique because Muppet characters are used to ease tensions associated with education about clinical interventions (Ramsay, 2014; Rohn, 2007). Yet the opening phrase 'Where the future is being made today' has, in my opinion, summed … …American Journal of Immunology, Vol. 12, Issue 2 · 28 Jun 2016 · 7,427 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSystematic Interpretation of the Factors of Federal Sustainability and Socio-Political Security of a Constituent State of a FederationYuliia Anatol’evna MatafonovaThe article deals with a constituent state of a federation, both a spatial unit of medium size, being an element of the federal system and as a local system having its own institutional, regulatory, cultural, ideological and communicative characteristics. In this article, we attempt to equate to some extent the federal sustainability and socio-political security of a constituent state of … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 26 Feb 2016 · 7,157 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA New Three-Term Preconditioned Gradient memory Algorithm for Nonlinear Optimization ProblemsAbbas Y. AL-Bayati, Ivan S. LatifIn the present study, we proposed a three-term of preconditioned gradient memory algorithms to solve a nonlinear optimization problem. The new algorithm subsumes some other families of nonlinear preconditioned gradient memory algorithms as its subfamilies with Powell's Restart Criterion and inexact Armijo line searches. Numerical experiments on twenty one well-known test functions with various dimensions generally encouraged and showed that … …Journal of Mathematics and Statistics, Vol. 4, Issue 2 · 30 Jun 2008 · 6,783 accessesView PDF Cite
