Research ArticleOpen accessEvery word in the titlePrivacy Preservation for File Sharing Scheme Using Secured File Block ID with Binary TreesM. Balamurugan, S. Chenthur Pandian, J. BhuvanaPrivacy, the security of information from unauthorized access is gradually needed on the Internet and yet progressively more important while each user acts as both consumer and producer. The lack of privacy is mainly employed for peer-to peer file sharing applications, in which users in the network shared file with each other and their actions are easily monitored by the … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 1 Jan 2013 · 6,928 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSome Applications of Spanning Trees in Complete and Complete Bipartite GraphsS. N. DaoudProblem statement: The number of spanning trees τ(G) in graphs (networks) is an important invariant, it is also an important measure of reliability of a network. Approach: Using linear algebra and matrix analysis techniques to evaluate the associated determinants. Results: In this study we derive simple formulas for the number of spanning trees of complete graph Kn and complete bipartite … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 15 Feb 2012 · 7,263 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumber of Spanning Trees of Circulant Graphs C6n and their ApplicationsS. N. DaoudProblem statement: The number of spanning trees of a graph G is usually denoted by τ(G). A circulant graph with n vertices and k jumps is Cn (a1,…..,ak). Approach: In this study the number τ(G) of spanning trees of the circulant graphs C6n with some non-fixed jumps such as C6n (1, n), C6n (1, n, 2n), C6n (1, n, 3n), … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 12 Dec 2011 · 7,626 accessesView PDFCite

Research ArticleOpen accessEvery word in the titleThe Effect of Adding Zeolite to Soils in Order to Improve the N-K Nutrition of Olive Trees. Preliminary ResultsR. Perez-Caballero, J. Gil, C. Benitez, J. L. GonzalezThis paper describes an experiment performed in order to study the possibility of using zeolite in organic olive groves. Soil and leaf analysis was performed and an increase in soil N levels was observed. Furthermore, higher levels of K in the soil and the trees point to the improved nutritional potential of these soils in terms of K, as a … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,392 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAntibiogram-Derived Radial Decision Trees: An Innovative Approach to Susceptibility Data DisplayRocco J. Perla, Paul P. BelliveauHospital antibiograms (ABGMs) are often presented in the form of large 2-factor (single organism vs. single antimicrobial) tables. Presenting susceptibility data in this fashion, although of value, does have limitations relative to drug resistant subpopulations. As the crisis of antimicrobial drug-resistance continues to escalate globally, clinicians need (1) to have access to susceptibility data that, for isolates resistant to first-line … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 6,502 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTree Rotations for Dependency Trees: Converting the Head-Directionality of Noun PhrasesIka Alfina, Indra Budi, Heru SuhartantoTo overcome the lack of NLP resources for the low-resource languages, we can utilize tools that are already available for other highresource languages and then modify the output to conform to the target language. In this study, we proposed an approach to convert an Indonesian constituency treebank to a dependency treebank by utilizing an English NLP tool (Stanford CoreNLP) to … …Journal of Computer Science, Vol. 16, Issue 11 · 17 Nov 2020 · 7,796 accessesView PDFCite
