Research ArticleOpen accessIn the abstractFunctional Link Artificial Neural Network for Classification Task in Data MiningB. B. Misra, S. DehuriIn solving classification task of data mining, the traditional algorithm such as multi-layer perceptron takes longer time to optimize the weight vectors. At the same time, the complexity of the network increases as the number of layers increases. In this study, we have used Functional Link Artificial Neural Networks (FLANN) for the task of classification. In contrast to multiple layer … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 60,797 accessesView PDFCite
Research ArticleOpen accessIn the abstractModified Hill Cipher with Interlacing and IterationV. U.K.. Sastry, N. Ravi ShankarIn this research, we have developed a block cipher by taking a large key matrix of size nxn and a plaintext matrix containing n rows and two columns. In this, the plaintext column vectors, perated by the key matrix are thoroughly interlaced at each stage of the iteration. As a typical example, we have taken the key in the form … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 7,353 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeaker Identification: A Hybrid Approach Using Neural Networks and Wavelet TransformMuzhir Shaban Al-Ani, Thabit Sultan Mohammed, Karim M. AljeboryIn speaker identification systems, a database is constructed from the speech samples of known speakers. The approach implemented in this paper is hybrid, where the wavelet transform and neural networks are used together to form a system with improved performance. Features are extracted by applying a discrete wavelet transform (DWT), while a neural network (NN) is used for formulating the … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 7,072 accessesView PDFCite
Research ArticleOpen accessIn the abstractObject Detection using Geometric Invariant MomentMohamed Rizon, Haniza Yazid, Puteh Saad et al.Geometric moment invariant produces a set of feature vectors that are invariant under shifting, scaling and rotation. The technique is widely used to extract the global features for pattern recognition due to its discrimination power and robustness. In this paper, moment invariant is used to identify the object from the captured image using the first invariant (Ø1). The recognition rate … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Oct 2006 · 6,663 accessesView PDFCite
Research ArticleOpen accessIn the abstractRotational Linear Discriminant Analysis Using Bayes Rule for Dimensionality ReductionAlok Sharma, Kuldip K. PaliwalLinear discriminant analysis (LDA) finds an orientation that projects high dimensional feature vectors to reduced dimensional feature space in such a way that the overlapping between the classes in this feature space is minimum. This overlapping is usually finite and produces finite classification error which is further minimized by rotational LDA technique. This rotational LDA technique rotates the classes individually … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,587 accessesView PDFCite
Research ArticleOpen accessIn the abstractSingle Stuck-At Fault Diagnosing Circuit of Reed-Muller Canonical Exclusive-Or Sum of Product Boolean ExpressionsP. N. Neelakantan, A. E. JeyakumarA testable design with a universal test set for single stuck-at zero and stuck-at one faults of Reed-Muller canonical form of Exclusive-OR sum of product logic expressions is proposed. The test circuit detects almost all the single stuck-at faults and needs only simple modifications for variations in the circuit under test. The number of test vectors is also quite small … …Journal of Computer Science, Vol. 2, Issue 7 · 31 Jul 2006 · 6,587 accessesView PDFCite
Research ArticleOpen accessIn the abstractImplementation of Load Balancing Algorithm in a Grid ComputingAbdallah Boukerram, Samira Ait Kaci AzzouThe emergence of the grid computing constituted by several resources stood out as platform of development for the industrial applications treating big quantities of data. In these environments of high- throughput computing, numerous researches were dedicated these last five years to the load balancing to make profitable the power of calculations in the grid. This paper describes the complete implementation … …American Journal of Applied Sciences, Vol. 3, Issue 4 · 30 Apr 2006 · 7,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractInteraction of a C-terminal Truncated Hepatitis C Virus Core Protein with Plasmid DNA Vaccine Leads to in vitro Assembly of Heterogeneous Virus-like ParticlesNelson Acosta-Rivero, Joanna Poutou, Alexis Mussachio et al.Recently, it has been shown that HCV core proteins (HCcAg) with C-terminal deletions assemble in vitro into virus-like particles (VLPs) in the presence of structured RNA molecules. Results presented in this work showed that a truncated HCcAg variant covering the first 120 aa (HCcAg.120) with a 32 aa N-terminal fusion peptide (6xHistag-XpressTMepitope) interacts with plasmid DNA vaccine. Interestingly, the buoyant … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,754 accessesView PDFCite
