Research ArticleOpen accessIn the author namesStability Analysis of a Class of Three-Neuron Delayed Cellular Neural NetworkPoulami Das Gupta, N. C. Majee, A. B. RoyProblem statement: In this study linear stability of a class of three neuron cellular network with transmission delay had been studied. Approach: The model for the problem was first presented. The problem is then formulated analytically and numerical simulations pertaining to the model are carried out. Results: A necessary and sufficient condition for asymptotic stability of trivial steady state in … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 7,598 accessesView PDF Cite

Research ArticleOpen accessIn the author namesStatistical Approach for Offline Handwritten Signature VerificationDebnath Bhattacharyya, Samir Kumar Bandyopadhyay, Poulami Das et al.Signatures were considered an important tool for authenticating the identity of human beings. So, signature verification was one of the biggest uses for that. We proposed an algorithmic approach for the verification of handwritten signatures by applying some statistical methods. The research work was based on the collection of set of signatures from which an average signature was obtained based … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 7,475 accessesView PDF Cite
