Research ArticleOpen accessIn the abstractCOMBINATION OF DIFFERENCE SUBSPACE AND OPPURTUNISTIC CLUSTERING ON HIGH DIMENSIONAL DATAM. Ravichandran, A. ShanmugamClustering is recognized as sigificant technique for analysing data and concentric effort has been taken in different domains comprises of recognition of pattern, statistical analysis and data mining for decades. Subspace clustering is developed from the group of cluster objects from all subspaces of a dataset. During clustering of objects involing higher dimension, the accuracy and effectiveness of traditional clustering … …Journal of Computer Science, Vol. 10, Issue 8 · 11 Mar 2014 · 6,359 accessesView PDFCite
Research ArticleOpen accessIn the abstractSTOCHASTIC GROWTH MODEL FOR SPATIAL CLUSTER BIRTH AND DEATH PROCESS WITH MIGRATIONRo’fah Nur Rachmawati, Rokhana Dwi BektiIn real life, we can encounter the cluster birth and death process with migration, such as the birth of new individuals and disease in certain place and time. These phenomena can be represented by stochastic model that are considered to be more representatives in capturing natural indications involving the concepts of space and time. In this study, we construct a … …Journal of Mathematics and Statistics, Vol. 9, Issue 2 · 9 May 2013 · 7,094 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination and Source Apportionment of Selected Heavy Metals in Aerosol Samples Collected from SebeleAlfred Sello Likuku, Gilbert Kabelo Gaboutloeloe, Khumoetsile B. MmolawaBush fires and dust in the dry winter months establish moderately high background levels of aerosols. Emissions into the atmosphere by copper mines, coal mines and vehicular emissions are all possible sources of air pollution with heavy metals. Although there has been assessment and monitoring of heavy metals and their air pollution in other countries such as Brazil, Europe and … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 25 Apr 2013 · 7,446 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiscrimination Capacity of RAPD, ISSR and SSR Markers and of their Effectiveness in Establishing Genetic Relationship and Diversity among Egyptian and Saudi Wheat CultivarsSalah El-Din El-Assal, Ahmed GaberProblem statement: Yield crop cultivars and landraces are valuable sources of genetic variations that the knowledge and implication of these variations are critical in the plant breeding programs. our major objective of this study is investigating the discriminating capacity of RAPD, ISSR and SSR markers and of their effectiveness in establishing genetic relationship and diversity among Egyptian and Saudi wheat … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 9 Mar 2012 · 7,774 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Hyper Clustering Algorithms in Mobile Network PlanningLamiaa Fattouh Ibrahim, Hesham A. SalmanProblem statement: As a large amount of data stored in spatial databases, people may like to find groups of data which share similar features. Thus cluster analysis becomes an important area of research in data mining. Applications of clustering analysis have been utilized in many fields, such as when we search to construct a cluster served by base station in … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 30 Aug 2011 · 7,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractLand use Type Pattern and Woody Species Composition Near Human Disturbed Landscapes on Mount Makiling, Luzon IslandInocencio E. Buot, Katsuhiro OsumiProblem statement: A field study near human disturbed landscape on Mount Makiling, Luzon Island, Philippines was done on the eastern slopes of the legendary mountain to determine the land use patterns and woody species composition. Approach: Forty permanent plots of 10×10m in 3 belt transects spaced at 200m apart were established from the undisturbed forests to the agricultural farms. Classification … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 26 Aug 2011 · 8,038 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Integrated Framework for Mixed Data Clustering Using Self Organizing MapHari Prasad Devaraj, M. PunithavalliProblem statement: Clustering plays an important role in data mining of large data and helps in analysis. This develops a vast importance in research field for providing better clustering technique. There are several techniques exists for clustering the similar kind of data. But only very few techniques exists for clustering mixed data items. This leads to the requirement of better … …Journal of Computer Science, Vol. 7, Issue 11 · 18 Aug 2011 · 7,307 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Clustering Techniques for Hyper Network Planning using Minimum Spanning Trees and Ant-Colony AlgorithmLamiaa Fattouh IbrahimProblem statement: The process of network planning is divided into two sub steps. The first step is determining the location of the Multi Service Access Node (MSAN). The second step is the construction of subscriber network lines from MSAN to subscribers to satisfy optimization criteria and design constraints. Due to the complexity of this process artificial intelligence and clustering techniques … …Journal of Computer Science, Vol. 7, Issue 3 · 9 Mar 2011 · 6,820 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of an Educational Scenario Exercise on Participants' Competencies of Systemic ThinkingSimon BurandtProblem statement: Education for sustainable development (ESD) aims to shape key competencies of individuals and therefore needs methods to enable learners to acquire these competencies. Systemic thinking can be regarded as a meta-competency in ESD, because it contains many important aspects found in most key competencies of ESD. Scenario analysis is described as a learning environment that fosters the acquisition … …Journal of Social Sciences, Vol. 7, Issue 1 · 18 Dec 2010 · 8,741 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Ethical and Non Ethical Mutual Funds ComparisonRosa Adamo, Angela Coscarelli, Domenica Federico, Antonella NotteProblem statement: One of the astonishing new developments in the financial community is the rise of ethical investments during the last decade. Particularly, the recent financial crisis has determined a major attention towards an ethically oriented finance based on social investments and environmental benefits that can create greater corporate crisis prevention.
