Research ArticleOpen accessEvery word in the titleDeveloping an Anthropometric Database for Saudi Students and Comparing Saudi Dimensions relative to Turkish and Iranian PeoplesMohamed A.A. MansourThe main objectives are to develop an anthropometric database for Saudi Students and to compare it relative to two other Middle Eastern people. A national anthropometric standard for Saudis does not exist and few studies have focused on the development of Saudis anthropometric data and the comparison of them with other races. The availability of these data is necessary to … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 24 Jun 2016 · 10,211 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA NEW METHOD FOR 3D SHAPE INDEXING AND RETRIEVAL IN LARGE DATABASE BY USING THE LEVEL CUTA. Lakehal, M. Elkhal, K. SatoriIn this study, we propose a new method for indexing and retrieval of 3D models in large databases based on binary images extracted from the 3D object called &#34level cut&#34 LC. These cuts are obtained by the intersection of the set of the plans with the 3D object. A set of equidistant parallel plans generates by the intersection with the … …Journal of Computer Science, Vol. 10, Issue 10 · 22 May 2014 · 6,827 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Fuzzy Fast Classification for Share Market Database with Lower and Upper BoundsSrinivasan Vaiyapuri, Rajenderan Govind, Vandar Kuzhali JaganathanIn recent years, many researchers focused on the research topic of constructing fuzzy classification system. This study introduces a Fuzzy Fast Classification (FFC) approach for large data sets. It has three phases, in the first phase the large data base is reduced with the entropy by removing the number of attribute. In the second phase an approximate classification is obtained … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 8 Nov 2012 · 6,674 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Secure Time-Stamp Based Concurrency Control Protocol For Distributed DatabasesShashi Bhushan, R. B. Patel, Mayank DaveIn distributed database systems the global database is partitioned into a collection of local databases stored at different sites. In this era of growing technology and fast communication media, security has an important role to play. In this paper we presented a secure concurrency control protocol (SCCP) based on the timestamp ordering, which provides concurrency control and maintains security. We … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,892 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Dynamic Temporal Neuro Fuzzy Inference System for Mining Medical DatabasesR. Sethukkarasi, A. KannanThe analysis and representation of temporal data are becoming increasingly important in many areas of research and application. The existing Fuzzy Cognitive Maps (FCMs) are efficient modeling method for knowledge representation and fuzzy reasoning in time series analysis. In the past, it was used to represent a complex causal system as a collection of concepts and causal relationships among concepts. … …Journal of Computer Science, Vol. 8, Issue 11 · 7 Nov 2012 · 6,360 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 titleMining Level-Crossing Association Rules from Large DatabasesR. S. Thakur, R. C. Jain, K. R. PardasaniExisting algorithms for mining association rule at multiple concept level, restricted mining strong association among the concept at same level of a hierarchy. However mining level-crossing association rule at multiple concept level may lead to the discovery of mining strong association among at different level of hierarchy. In this study, a top-down progressive deepening method is developed for mining level-crossing … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,317 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDeveloping a Prototype for Sun Tracker System Based on IoT: Controlled by Mobile App and Online Database MonitoringIsmail Ismail Yusuf Panessai, Muhammad Modi bin Lakulu, Siva Kumar A/L Subramaniam et al.IoT (Internet of Things) has become a separate research field since the development of internet technology and other communication media. IoT optimizes several tools such as sensor media radio frequency identification, wireless sensor networks and other smart objects that allow humans to easily interact with all devices connected to the internet network. The purpose of this research is to build … …American Journal of Applied Sciences, Vol. 16, Issue 1 · 11 Feb 2019 · 8,770 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleITERATIVE DICHOTOMISER-3 ALGORITHM IN DATA MINING APPLIED TO DIABETES DATABASEP. VasudevanIn this study, eight major factors playing significant role in the Pima Indian population are analyzed. Real time data is taken from the large dataset of National Institute of Diabetes and Digestive and Kidney Diseases. The data is subjected to an analysis by logistic regression method using SPSS 7.5 statistical software, to isolate the most significant factors among the eight … …Journal of Computer Science, Vol. 10, Issue 7 · 15 Feb 2014 · 7,082 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHandling Web and Database Requests Using Fuzzy Rules for Anomaly Intrusion DetectionSelvamani Kadirvelu, Kannan ArputharajProblem statement: It is necessary to propose suitable detection and prevention mechanisms to provide security for the information contents used by the web application. Many prevention mechanisms which are currently available are not able to classify anomalous, random and normal request. This leads to the problem of false positives which is classifying a normal request as anomalous and denying access … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,307 accessesView PDFCite
