Reinforcement learning has gained wide popularity as a technique for simulation-driven approximate dynamic programming. A less known aspect is that the very reasons that make it effective in dynamic programming can also be leveraged for using it for distributed schemes for certain matrix computations involving non-negative matrices. In this spirit, we propose a reinforcement learning algorithm ...

PageRank is one of the principle criteria according to which Google ranks Web pages. PageRank can be interpreted as the frequency that a random surfer visits a Web page, and thus it reflects the popularity of a Web page. We study the effect of newly created links on Google PageRank. We discuss to what extent a page can control its PageRank. Using asymptotic analysis we provide simple conditions...

We propose a web application based security system. When a user interacts with a computing system to enter a secret password, shoulder surfing attacks are of great concern. This system overcomes the problem of shoulder surfing. Previous system proposed a methodology in which the user has to remember all the events performed. This limits the system usage. Our novel approach enhances the shoulder...

The charnockitic and associated granitic rocks of Akure area were studied for their field and petrographic relationship's. The outcrops locations were plotted in Surfer 8. The granitic rock exhibits a porphyritic texture and outcrops in the north-eastern side of the study area while the charnockitics outcrop in the central/western part. An essentially dark coloured and fine grained intrusive ex...

Search Engine spam is a web page or a portion of a web page which has been created with the intention of increasing its ranking in search engines. Web spamming refers to actions intended to mislead search engines and give some pages higher ranking than they deserve. Anyone who uses a search engine frequently has most likely encountered a high ranking page that consists of nothing more than a bu...

Purpose: Cognitive impairment is commonly observed in patients with Temporal Lobe Epilepsy (TLE). Recently, volumetric analysis showed widespread cortical and subcortical atrophy in patients with TLE. In this study, we hypothesized that the diffuse atrophy in TLE with and without Mesial Temporal Sclerosis (MTS) was associated with cognitive impairment. Methods: To investigate atrophy patterns i...
