Research ArticleOpen accessIn the abstractVision Based Reconstruction Multi-Clouds of Scale Invariant Feature Transform Features for Indoor NavigationAbbas M. Ali, Md Jan NordinProblem statement: Navigation for visually impaired people needs to exploit more approaches for solving problems it has, especially in image based methods navigation. Approach: This study introduces a new approach of an electronic cane for navigation through the environment. By forming multi clouds of SIFT features for the scene objects in the environment using some considerations. Results: The system gives … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,225 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIndoor Navigation and Localization for Visually impaired people Using Weighted Topological MapMd Jan Nordin, Abbas M. AliProblem Statement: Image base methods are a new approach for solving problems of navigations for visually impaired people. Approach: The study introduced a new approach of an electronic cane for blind people using the environment represented as a weighted topological graph instead, each node contains images taken at some poses in the work space, instead of building a metric (3D) … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 7,423 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIn silico Analysis of three Committed-Steps Involved in Triterpenoid Biosynthesis from Ganoderma lucidumXiaorong Shui, Xiaozhong Lan, Wei LeiGanoderma lucidum is widely considered as one of the most valuable Traditional Chinese Medicines, with various bioactive constituents and pharmaceutical effects. Triterpenoids are important effective ingredients of G. lucidum, which are synthesized mainly through the mevalonate pathway. In this study, we aimed to characterize and analyze three committed-step enzymes of the mevalonate pathway, 3-Hydroxy-3-Methylglutaryl-Coenzyme A Reductase (HMGR), Farnesyl Diphosphate Synthase … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 3 · 15 Aug 2016 · 7,349 accessesView PDF Cite

EditorialOpen accessIn the abstractProblems of Ultra-High Energy Cosmic RaysAnna V. UrysonCosmic rays are energetic particles coming to the Earth from space. They bombard the atmosphere producing cascades of particles that spread over a large area when they reach the ground. Cosmic ray energies vary in the wide band from about 108 eV up to few 1020 eV. It is established that most particles with energies of ~ (108-109) eV come … …Space Science International, Vol. 2, Issue 1 · 6 Dec 2014 · 13,865 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordIdentification of Influential Nodes With Topological Structure Via GRAPH Neural Network (GNN) Approach in Social Media NetworksRajnish Kumar, Laxmi Ahuja, Suman Mann, Sanmukh KaurThe amount of data in social networks is vast these days, and constantly changing, making influential node identification crucial. The existing topologies are constantly changing due to the evolving behavior of the applied dataset. Node and leaf topology or feature-based value form the basis for machine learning and centrality computation. Hence, influential node value determination is based on the node … …Journal of Computer Science, Vol. 22, Issue 2 · 17 Feb 2026 · 1,836 accessesView PDF Cite
