Research ArticleOpen accessIn the author namesPARALLEL IMPLEMENTATION OF EXPECTATION-MAXIMISATION ALGORITHM FOR THE TRAINING OF GAUSSIAN MIXTURE MODELSG. F. Araújo, H. T. Macedo, M. T. Chella et al.Most machine learning algorithms need to handle large data sets. This feature often leads to limitations on processing time and memory. The Expectation-Maximization (EM) is one of such algorithms, which is used to train one of the most commonly used parametric statistical models, the Gaussian Mixture Models (GMM). All steps of the algorithm are potentially parallelizable once they iterate over … …Journal of Computer Science, Vol. 10, Issue 10 · 9 Jul 2014 · 6,940 accessesView PDFCite
Research ArticleOpen accessIn the author namesOptimisation of Bromelain Enzyme Extraction from Pineapple (Ananas comosus) and Application in Process IndustryResmi Mohan, Venkatasubramanian Sivakumar, Thirumalaisamy Rangasamy, Chellappa MuralidharanBromelain is a general name for a family of sulfhydryl proteolytic enzymes obtained from Ananas comosus, the pineapple plant. The objective of the present study is to compare the activity of Bromelain from pineapple fruit and peel and to check the efficiency of this crude Bromelain enzyme in unhairing step in leather processing. The crude Bromelain was extracted and activity … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 3 · 19 Sep 2016 · 12,652 accessesView PDFCite
Research ArticleOpen accessIn the author namesTrust Based Node Replication Attack Detection Protocol for Wireless Sensor NetworksV. Manjula, C. ChellappanThe harmful attack against Wireless Sensor Networks (WSN) is Node Replication attack, where one or more node(s) illegitimately claims an identity, are also called clone attack due to identity theft. The Node replication attack can be exceedingly injurious to many important functions of the sensor network such as routing, resource allocation, misbehavior detection, This study proposes a method Randomized and … …Journal of Computer Science, Vol. 8, Issue 11 · 5 Nov 2012 · 6,759 accessesView PDFCite
