Research ArticleOpen accessEvery word in the titleFunctional Non-Inferiority Hypothesis Testing for Longitudinal DataArsène Brunelle Sandie, Anthony Wanjoya, Jules Brice Tchatchueng-MbouguaThe study pattern of non-inferiority trials is increasingly used to show the non-inferiority of new health intervention. Although in such studies the data are longitudinally collected (data held over a period of time), the conclusion of these non-inferiority trials is based on data observed at a specific time during the study period (usually at the end of the study period). … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 29 Aug 2019 · 6,936 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGlobal Test for Superiority and Non-Inferiority Trials with Functional Endpoints DataArsene Brunelle Sandie, Jules Brice Tchatchueng-Mbougua, Anthony WanjoyaThe global two-sided test for functional means difference got much attention in the literary works. While the global one-sided test for functional means difference has not been studied. However, that could have some applications and implications for longitudinal trials or trials with functional data outcomes. This work introduced superiority and noninferiority hypothesis tests for functional data outcomes, which were viewed … …Current Research in Biostatistics, Vol. 9, Issue 1 · 8 Jul 2019 · 12,662 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMining Functional Dependency from Relational Databases Using Equivalent Classes and Minimal CoverJalal Atoum, Dojanah Bader, Arafat AwajanData Mining (DM) represents the process of extracting interesting and previously unknown knowledge from data. This study proposes a new algorithm called FD_Discover for discovering Functional Dependencies (FDs) from databases. This algorithm employs some concepts from relational databases design theory specifically the concepts of equivalences and the minimal cover. It has resulted in large improvement in performance in comparison with … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,879 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFunctional Link Artificial Neural Network for Classification Task in Data MiningB. B. Misra, S. DehuriIn solving classification task of data mining, the traditional algorithm such as multi-layer perceptron takes longer time to optimize the weight vectors. At the same time, the complexity of the network increases as the number of layers increases. In this study, we have used Functional Link Artificial Neural Networks (FLANN) for the task of classification. In contrast to multiple layer … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 60,801 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of the Prospects for Developing Storage and Processing Complexes for Multiformat Media DataVladimir Zhanovich Kuklin, Islam Alexandrovich Alexandrov, Alexander Alexandrovich Umyskov, Abas Khasanovich LampezhevA distinctive feature of multifunctional systems for supporting multimedia services on a single platform is the heterogeneity of incoming streams and requests, which requires optimization of resource use under physical constraints. In this regard, it is relevant to develop promising proposals for the functional structure and technical characteristics of complexes for storing and processing multi-format media data, which was the … …Journal of Computer Science, Vol. 18, Issue 12 · 6 Dec 2022 · 5,581 accessesView PDFCite
Research ArticleOpen accessIn the keywordsClinical and Functional Profile of Amyotrophic Lateral Sclerosis Patients: A One Year Follow UpMarco Orsini, Marcos R.G. de Freitas, Osvaldo J.M. Nascimento et al.Problem statement: Amyotrophic Lateral Sclerosis (ALS) is a progressive and degenerative disease that affects the anterior horn motor neurons of the spinal cord and pyramidal tracts. In Brazil, there are few epidemiological data on this disease. Recently, some important findings have been reported, allowing a better understanding on the underlying processes of neuronal death, as well as the characteristics of … …Neuroscience International, Vol. 2, Issue 1 · 6 Oct 2011 · 7,777 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNormalized Relational Storage for Extensible Markup Language (XML) SchemaKamsuriah Ahmad, Reduan SamadProblem statement: The use of XML as the common formats for representing, exchanging, storing, integrating and accessing data posses many new challenges to database systems. Most of application data are stored in relational databases due to its popularity and rich development experiences over it. Therefore, how to provide a proper mapping approach from XML model to relational model become the … …Journal of Computer Science, Vol. 7, Issue 11 · 24 Aug 2011 · 6,840 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExtending the Concepts of Normalization from Relational Databases to Extensible-Markup-Language Databases ModelH.J. F. El-SofanyIn this study we have studied the problem of how to extend the concepts of Functional Dependency (FD) and normalization in relational databases to include the eXtensible Markup Language (XML) model. We shown that, like relational databases, XML documents may contain redundant information and this redundancy may cause update anomalies. Furthermore, such problems are caused by certain functional dependencies among … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 6,464 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSWITCHING-ALGEBRAIC ANALYSIS OF RELATIONAL DATABASESAli Muhammad Ali Rushdi, Omar Mohammed Ba-RukabThere is an established equivalence between relational database Functional Dependencies (FDs) and a fragment of switching algebra that is built typically of Horn clauses. This equivalence pertains to both concepts and procedures of the FD relational database domain and the switching algebraic domain. This study is an exposition of the use of switching-algebraic tools in solving problems typically encountered in … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 18 Apr 2014 · 6,708 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Water Bath Heating on Tannin Content and Quality Improvement Potential of Gambier (Uncaria gambir Roxb.)Daimon Syukri, Bastian Nova, Rina Yenrina et al.Gambir (Uncaria gambir Roxb.) is a source of natural phenolic compounds rich in catechins and tannins and has potential as a sustainable industrial raw material. During heating, phenolic compounds may undergo structural changes, including possible oxidation and polymerization, which can affect gambier quality beyond its catechin content. This study evaluated the effect of indirect heating duration using a water bath … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 23 Sep 2026 · 715 accessesView PDFCite
