Research ArticleOpen accessIn the abstractInterest-based Recommendation in Digital LibraryYan Yang, Jian Zhong LiWith the huge amount and large variety of information available in a digital library, it’s becoming harder and harder for users to identify and get hold of their interested documents. To alleviate the difficulty, personalized recommendation techniques have been developed. Current recommendation techniques rely on similarity between documents. In our work, recommendations are made based on three factors: similarity between … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 7,011 accessesView PDFCite
Research ArticleOpen accessIn the abstractEpidemiological Models Applied to Viruses in Computer NetworksJos R.S. Piqueira, Betyna F. Navarro, Luiz H.A. MonteiroTo investigate the use of classical epidemiological models for studying computer virus propagation we described analogies between computer and population disease propagation using SIR (Susceptible-Infected-Removed) epidemiological models. By modifying these models with the introduction of anti-viral individuals we analyzed the stability of the disease free equilibrium points. Consequently, the basal virus reproduction rate gives some theoretical hints about how to … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 7,574 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Model for the CD4 Cell Counts in an HIV/AIDS Patient and its Application in Treatment InterventionsRichard O. Simwa, Joseph Y.T. MugishaThe number of CD4 white blood cells has been established as an important clinical marker of disease progression to acquired immunodeficiency syndrome (AIDS) for persons infected with human immunodeficiency virus (HIV). The number of CD4 cells per unit volume is expected to decrease with time since infection by the virus. However on introduction of treatment interventions, the process is expected … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,842 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Cathodically Charged Hydrogen on the Microhardness of Pure CopperGhazi S. AL-Marahleh, Amjad S. El-AmoushThe effect of hydrogen on the microhardness of pure copper was investigated after experiments conducted on specimens that hydrogen charged under different cathodic charging conditions. Microhardness measurements revealed that the introduction of hydrogen caused hardening on the surface of copper. The severity of the hardened region increased with either cathodic current density or charging time. Further charging increased the depth … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,280 accessesView PDFCite
