Research ArticleOpen accessIn the abstractProgressive Resistance Training on Elderly HIV+ Patients: Does it Work?Paula Maria Loiola De Souza, Wilson Jacob Filho, José Maria Santarém et al.Elderly people present significant alterations on body composition and physical fitness, compromising their quality of life. Chronic diseases, including HIV/AIDS, worsen this situation by increasing aging effects on body composition and muscle strength. Resistance exercises are prescribed by major health organizations for improving fitness and promoting a shift towards a healthier and more independent aging. In addition, recovering strength and … …American Journal of Infectious Diseases, Vol. 4, Issue 4 · 31 Dec 2008 · 6,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Evaluation of Medium Access Schemes in 802.11 Wireless NetworksG. Singh, B. S. SohiProblem statement: Deployment of real time services over 802.11 wireless networks requires quality of service (QoS) differentiation mechanisms for different traffic types. This required investigations into the performance of the Medium access (MAC) schemes like Distributed Coordinated Function (DCF) and Enhanced DCF with respect to the stringent QoS requirements imposed by the real time services. Motivation for this research was … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 7,136 accessesView PDFCite

Research ArticleOpen accessIn the abstractJitter Characterization in Admission Control and Pricing Issues in Integrated Multiservice NetworksFabien Houéto, Samuel PierreThis paper analyses the pricing framework of multiservice networks and proposes an improved pricing scheme based on the effective bandwidth concept for taking into account quality of service parameters. Based on the deficiencies noted in the classical effective bandwidth scheme (intolerance to user uncertainty and no guarantee on jitter), we propose an improved charging function which gives more flexibility to … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 7,028 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fuzzy Approach for Integrated Measure of Object-Oriented Software TestabilityVandana Gupta, K. K. Aggarwal, Yogesh SinghFor large software systems, testing phase seems to have profound effect on the overall acceptability and quality of the final product. The success of this activity can be judged by measuring the testability of the software. A good measure for testability can better manage the testing effort and time. Different Object Oriented Metrics are used in measurement of object-oriented testability … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 7,905 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved Performance of Traffic Dependent Outage Rate Cellular SystemHussein M.A. Basi, M. B.R.
