Research ArticleOpen accessIn the abstractA Light-Weight Service Discovery Protocol for Ad Hoc NetworksRanwa Al Mallah, Alejandro QuinteroProblem statement: In mobile ad hoc networks devices do not rely on a fixed infrastructure and thus have to be self-organizing. This gives rise to various challenges to network applications. Existing service discovery protocols fall short of accommodating the complexities of the ad-hoc environment. However, the performance of distributed service discovery architectures that rely on a virtual backbone for locating … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,343 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultiple Pulmonary and Multivesicular Interatrial Septum Hydatid Cysts in A Native Italian PatientA. Romano, S. Giordano, F. Follis et al.Multivesicular, pulmonary and cardiac hydatidosis are rarely observed and can give rise to serious complications. Cysts can remain asymptomatic for a long time, until they reveal themselves perforating into cardiac chambers and/or pulmonary arteries or the systemic circulation. A rare case of multivesicular interatrial septum hydatid cyst with multiple pulmonary involvement in a native Italian farm labourer is reported. Clinical, … …American Journal of Infectious Diseases, Vol. 4, Issue 3 · 30 Sep 2008 · 6,897 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Changing Pathology of NeuroAIDS Associated with Drug Abuse in the Era of HAARTE Bell Jeanne, C. Anthony Iain, Simmonds PeterCompliance with highly active antiretroviral therapy (HAART) arrests HIV induced immune collapse and reduces the prevalence of severe central nervous system (CNS) complications, including HIV associated dementia and encephalitis. However minor cognitive disorders remain common and recent autopsy studies have demonstrated the presence of subtle neuropathological abnormalities in HAART treated individuals, including persistent neuroinflammation and enhanced deposition in the brain … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 6,874 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Analysis of the Output and Employment Conversion Matrices of Australia's EconomyAbbas Valadkhani, Tim RobinsonBased on two snapshots taken from the Australian economy, this study quantifies the impacts of final demand aggregates on output and employment in various sectors using the 1989 and 1997 conversion matrices. The sectoral output and employment are linked with final demand deliveries in such a way that one can measure the impacts on changes in each component of aggregate … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,752 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Developmental Psychology to Understanding History, Culture and Social ChangeGeorg W. OesterdiekhoffDevelopmental psychology of the past generations has evidenced that the whole pre-modern humankind stood on pre-operational or concrete-operational stages. Only the modern humankind has also developed the fourth stage of human development, the adolescent stage of formal operations. Lew Vygotski was 1933 one of the first to earmark convincingly the connection of socialisation (school education) and cognitive development as a … …Journal of Social Sciences, Vol. 10, Issue 4 · 29 Jan 2015 · 12,915 accessesView PDFCite
Research ArticleOpen accessIn the abstractLong Cycles in Employment, Inflation and Real Unit Wage Costs, Qualitative Analysis and Quantitative AssessmentPeter Flaschel, Goeran Kauermann, Timo TeuberThis study provided some theoretical foundations for the empirical hypothesis. At first presented two simple prototype models of inflation, stagflation and disinflation. We concluded that there are cycles with a phase length much longer than the ordinary business cycle (in fact approximately five times as long as we saw in the empirical phase plots of the paper) which are not … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 18 Dec 2005 · 8,592 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCase Study on the Effects of Plan Irregularities on Seismic Performance of StructuresEduardo Flores, Tadeh ZirakianGeometric configurations, such as large openings, re-entrant corners, and discontinuity in diaphragms, are very common in architectural design but are seen as undesirable for structural performance during earthquakes. The lateral systems in a structure resist the strong forces induced during an earthquake, preventing damage or collapse of the structure. If these systems fail, the structural integrity of the building may … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 21 Jul 2024 · 5,726 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordVisual Contact between Two Earth’s SatellitesM. E. Awad, M. A. Sharaf, E. H. KhatabProblem statement: In this study, an analytical expression for predicting mutually visible between Earth’s satellites is developed. Approach: A relative satellite-satellite visibility function is developed in terms of orbital elements for two satellites in the same orbital plane. Also, a simple computational algorithm is expressed to compute the visibility function. Results: This study presents a new and easy method to … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 27 Feb 2012 · 6,983 accessesView PDFCite
