Research ArticleOpen accessIn the keywordsA Grade-Based Incentive Mechanism for Peer-to-Peer NetworksS. Moses Dian, B. RamadossFree-riding is a desperate and a constant menace to many P2P systems, to violate the cooperation among peers. This study proposes a grade-based approach, which expeditiously maintains fairness in the network by encouraging the high contributed peers and altogether wiping out the free-riders. The Network Contribution Ratio determines the contribution of users globally. Besides, the proposed grading algorithm uses a … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 3 · 3 Sep 2012 · 7,489 accessesView PDFCite

EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDFCite
