Research ArticleOpen accessIn the abstractLog data Approach to Acquisition of Optimal Bayesian Learner ModelChoo-Yee Ting, Somnuk Phon-AmnuaisukLog data provide valuable insight into observable behavioural patterns, which could be inferred to study a learner’s cognitive processes, levels of motivation and levels of knowledge acquisition. To date, most of the research work has been devoted to study the different methods to analyze and interpret log data. Little attention, however, has been given to use log data as a … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,082 accessesView PDFCite
Research ArticleOpen accessIn the abstractElucidating the Mechanism(s) of Hormesis at the Cellular Level: The Universal Cell ResponsePaul S. AgutterMany environmental stressors elicit biphasic effects from single cells. Such cellular hormesis may be interpreted in terms of (a) the superimposition of simple biochemical processes or (b) the non-specific behaviour of the cell. The latter approach is emphasized in this article and identified with the universal cell response (UCR); however, the importance of identifying molecular-level concomitants of the UCR is … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 13,118 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomatic Arabic Hand Written Text Recognition SystemIsmael Ahmad JannoudDespite of the decent development of the pattern recognition science applications in the last decade of the twentieth century and this century, text recognition remains one of the most important problems in pattern recognition. To the best of our knowledge, little work has been done in the area of Arabic text recognition compared with those for Latin, Chins and Japanese … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 7,319 accessesView PDFCite
Research ArticleOpen accessIn the abstractRecovery in Distributed Systems from Transient and Permanent FaultsM. Aliouat, Z. AliouatThe recovery mechanism from transient fault in distributed systems has been intensively studied in the past, but to our best knowledge, none of these studies has been devoted to cope together with transient and permanent hard faults. Our study devoted to recovery processes in a distributed environment in case of hard faults like transient or permanent. The recovery mechanism we … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,860 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputer Simulator: An Educational Tool for Computer ArchitectureMihyar HessonThe great advancement in computer architecture and cache memory design and technology had a considerable influence on the way computer architecture was taught in universities. This requires students to be able to visualize the detailed activities that take place within a computer processor and its interaction with memory system. Computer simulators could effectively be used to enhance the understanding and … …American Journal of Applied Sciences, Vol. 3, Issue 11 · 30 Nov 2006 · 7,475 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Postgenomic Era: Transcriptomic as the New Paradigm of LifeBruno Giardina, Marcella Renis, Vito Latora, Salvatore MusumeciNow that complete genome sequences are available for a variety of organism, the elucidation of single gene function involved in the metabolism, includes necessarily a better understanding of the cellular responses on all levels of gene products, mRNA, proteins and metabolites. Such knowledge’s growth is essential since the observable properties of living organisms, so called phenotypes, are the results of … …OnLine Journal of Biological Sciences, Vol. 6, Issue 1 · 30 Jun 2006 · 6,826 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarly Cellular Responses of Purine Nucleoside-mediated Protection of Hypoxia-induced Injuries of Neuronal PC12 CellsBettina Tomaselli, Valerie Podhraski, Günther Böck, Gabriele Baier-BitterlichHypoxia in brain may lead to cell death by apoptosis and necrosis. In parallel adenosine, a powerful endogenous neuroprotectant is formed. We wanted to investigate the effect of adenosine and its purine nucleoside relatives, inosine and guanosine on early cellular responses to hypoxia. O2-sensitive neuronal PC12-cells were subjected to chemical hypoxia induced with rotenone, an inhibitor of mitochondrial complex I. … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,858 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordVirtual Learning System with Artificial Intelligence for the Academic Management ProcessLuis Lopez-Zevallos, Evellyn Navarro-Prado, Michael Cabanillas-CarbonellThe impact of the COVID-19 pandemic on global education, with the massive closure of schools and universities. It highlights the challenge of adapting to distance learning modalities and the loss of students' knowledge. In this context, the use of Artificial Intelligence (AI) has become a promising alternative to improve distance education; it is presented as a solution to automate administrative … …Journal of Computer Science, Vol. 21, Issue 4 · 6 Mar 2025 · 5,373 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordA Faulty Solar Panel Detecting and Mapping Method Using aDrone with RGB and Thermal Cameras in Solar Power PlantSoobin Jeon, Dongmahn SeoA solar panel generates electricity power using the sun's rays. It isusually located on a rooftop or open field without shadow. This solar panelis hard to be tested by nonprofessionals. Therefore, we propose a detectingsystem for a faulty solar panel using a drone with an RGB camera and athermal camera. The drone is applied for collecting aerial videos. The RGBcamera … …Journal of Computer Science, Vol. 21, Issue 5 · 21 May 2025 · 4,599 accessesView PDFCite
