  1. Neutrosophic Association Rule Mining Algorithm for Big Data Analysis.Mohamed Abdel-Basset, Mai Mohamed, Florentin Smarandache & Victor Chang - 2018 - Symmetry 10 (4):1-19.
    Big Data is a large-sized and complex dataset, which cannot be managed using traditional data processing tools. Mining process of big data is the ability to extract valuable information from these large datasets. Association rule mining is a type of data mining process, which is indented to determine interesting associations between items and to establish a set of association rules whose support is greater than a specific threshold. The classical association rules can only be extracted from binary data where an (...)

  7. Radical religious thought in Black popular music. Five Percenters and Bobo Shanti in Rap and Reggae.Martin Abdel Matin Gansinger - 2017 - Hamburg, Germany: Anchor.
    This book is discussing patterns of radical religious thought in popular forms of Black music. The consistent influence of the Five Percent Nation on Rap music as one of the most esoteric groups among the manifold Black Muslim movements has already gained scholarly attention. However, it shares more than a strong pattern of reversed racism with the Bobo Shanti Order, the most rigid branch of the Rastafarian faith, globally popularized by Dancehall-Reggae artists like Sizzla or Capleton. Authentic devotion or calculated (...)

  9. Neutrosophic Integer Programming Problem.Mai Mohamed, Mohamed Abdel-Basset, Abdel Nasser Zaied & Florentin Smarandache - 2017 - Neutrosophic Sets and Systems 15:3-7.
    In this paper, we introduce the integer programming in neutrosophic environment, by considering coffecients of problem as a triangulare neutrosophic numbers. The degrees of acceptance, indeterminacy and rejection of objectives are simultaneously considered. The Neutrosophic Integer Programming Problem (NIP) is transformed into a crisp programming model, using truth membership (T), indeterminacy membership (I), and falsity membership (F) functions as well as single valued triangular neutrosophic numbers. To measure the efficiency of the model, we solved several numerical examples.

  16. Is perception cognitively penetrable? A philosophically satisfying and empirically testable reframing.Gary Lupyan, Dustin Stokes, Fiona Macpherson, Rasha Abdel Rahman & Robert Goldstone - 2013 - Proceedings of the 35th Annual Conference of the Cognitive Science Society 1:91-2.
    The question of whether perception can be penetrated by cognition is in the limelight again. The reason this question keeps coming up is that there is so much at stake: Is it possible to have theory-neutral observation? Is it possible to study perception without recourse to expectations, context, and beliefs? What are the boundaries between perception, memory, and inference (and do they even exist)? Are findings from neuroscience that paint a picture of perception as an inherently bidirectional and interactive process (...)

  17. Mechanism of development of pre-eclampsia linking breathing disorders to endothelial dysfunction.Jerath Ravinder, Vernon A. Barnes & Hossam E. Fadel - 2009 - Medical Hypotheses 73:163-166.
    High blood pressure is an important component of pre-eclampsia. The underlying mechanism of development of hypertension in pre-eclampsia is complicated and still remains obscure. Several theories have been advanced including endothelial dysfunction, uteroplacental insufficiency leading to generalized vasoconstriction, increased cardiac output, and sympathetic hyperactivity. Increased blood flow and pressure are thought to lead to capillary dilatation, which damages end-organ sites, leading to hypertension, proteinuria and edema. Additional theories have been put forward based on epidemiological research, implicating immunological and genetic factors. (...)
