Research ArticleOpen accessAll words, across the recordSecured Disclosure of Sensitive Data in Data Mining TechniquesKirubhakar Gurusamy, Venkatesh ChakrapaniRecent advances in data collection, data dissemination and related technologies have inaugurated a new era of research where existing data mining algorithms should be reconsidered from the point of view of securing sensitive data. People have become increasingly unwilling to share their data. This frequently results in individuals either refusing to share their data or providing incorrect data. In turn, … …Journal of Computer Science, Vol. 8, Issue 12 · 18 Dec 2012 · 6,484 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMeasuring the Relevance of Trajectory Matching and Profile Matching in the Context of Carpooling Computational SystemsMichael Cruz, Hendrik Macedo, Adolfo GuimarãesCarpooling consists of sharing individual vehicle space among people with comparable trajectories. Although there are some software initiatives to help carpooling practice, none of them really implements features similarly to searching for people with similar trajectories and profile. In this study, we propose an innovative approach to generate clusters of users that share similar trajectories and profile for carpooling purposes … …Journal of Computer Science, Vol. 14, Issue 2 · 3 Feb 2018 · 8,133 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDevelopment of an Energy-Efficient, Secure and Reliable Wireless Sensor Networks Routing Protocol Based on Data Aggregation and User AuthenticationA. Gopi Saminathan, S. KarthikData aggregation protocols are required in Wireless Sensor Networks (WSNs) to improve the data accuracy and extend the network lifetime by reducing the energy consumption. The existing Data Aggregation-Optimal LEACH (DAO-LEACH) protocol for WSN is enhanced in terms of security and fault-tolerance based on Gracefully Degraded Data Aggregation (GDDA) to ensure the integrity of the aggregated data and Hybrid Layer … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 6,860 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA New Scalable and Reliable Cost Effective Key Agreement Protocol for Secure Group CommunicationS. Jabeen Begum, Dr. T. PurusothamanProblem statement: In a heterogeneous environment, for a secure multicast communication, the group members have to share a secret key which is used to encrypt/decrypt the secret messages among the members. The Secure Group Communication of large scale multicast group in a dynamic environment is more complex than securing one-to-one communication due to the inherent scalability issue of group key … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,966 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOptimization of Clustering Time by a Group of Autonomous Robots Making Use of an Exclusive Multi-MarkingMohamed Rida Abdessemed, Kamel Khoualdi, Azeddine BilamiProblem statement: For solving complex issues, the current tendency goes towards the swarms behaviors, realized on a basis of collective interactions, which results from a cooperative work favoring exchanges between individuals of a same group at microscopic level and allowing the emergence of complex collective behaviors at macroscopic level. Many models were inspired by these attitudes to find simple rules, … …Journal of Computer Science, Vol. 6, Issue 12 · 9 Nov 2010 · 6,892 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordInvestigation of the Characteristics of Thulium Doped Alumina Nanoparticles for Applications in Silica-Based FibersNur Atiqa Bt Rahmat, Hairul Azhar Abd Rashid, H.Y. Wong, Mukter ZamanIt is reported that during the fabrication of doping RE ions into the silica preform, the distribution of particles is inhomogeneous and becomes uneven throughout the fiber which lead to unwanted spectroscopic characteristics. It is assumed that by using thulium doped with alumina, the problem with the inhomogeneity of the particles inside the fiber can be solved. With the incorporation … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 26 Jan 2017 · 7,413 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordGOVERNMENTAL CONTROL OF THE FORMATION EFFICIENCY OF EDUCATIONAL CLUSTERS AT THE REGIONAL LEVELNina Ivanovna Larionova, Tatiana Valerievna Yalyalieva, Dmitry Leonidovich Napolskikh, Victor Evgenevich ShebashevStudying the cluster institutionalization processes in the modern practices of the social development allows determining the formation trends of an efficient governmental control system at the subfederal level. The efficiency parameters suggested by the author for the cluster policy implementation for the governmental control purposes, such as density, integrity, complementarity and institutional sphere conductivity will allow controlling the development efficiency … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 1 Dec 2014 · 5,636 accessesView PDFCite
