Research ArticleOpen accessIn the abstractGeo-Seismic Environmental Aspects Affecting Tailings Dams FailuresJuan M. Mayoral, Miguel P. RomoSeismic performance evaluations of tailings dams are essential for characterizing the geo-environmental risks posed by these earthen structures, which should include the geotechnical hazards implied by slope instability failure, free board loss and the potential release of contaminants. The observed damage is more important when liquefaction occurs on the dam body and foundation, which often leads to cracking, settlements, tilting … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,086 accessesView PDFCite
Research ArticleOpen accessIn the abstractCustomized Privacy Preservation Using Unknowns to Stymie Unearthing Of Association RulesJ. Indumathi, G.V. UmaThe explosions of new data mining techniques has augmented privacy risks because now it is probable to powerfully coalesce and cross-examine massive data stores, accessible on the web, in the rummage around of earlier unidentified hidden patterns. Consecutively to make a overtly accessible system safe and sound, we must guarantee not only that private sensitive data have been trimmed out, … …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 7,117 accessesView PDFCite
Research ArticleOpen accessIn the abstractGroundwater Nitrate Contamination Risk Assessment: A Comparison of Parametric Systems and Simulation ModellingDario Sacco, Marco Offi, Marina De Maio, Carlo GrignaniGroundwater nitrate contamination is a source of rising concern that has been faced through the introduction of several regulations in different countries. However the methodologies used in the definition of Nitrate Vulnerable Zones are not included in the regulations. The aim of this work was to compare different methodologies, used to asses groundwater nitrate contamination risks, based on parametric systems … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,122 accessesView PDFCite
Research ArticleOpen accessIn the abstractProximity Aware Routing in Ad Hoc NetworksValerie Alandzi, Alejandro QuinteroMost of the existing routing protocols for ad hoc networks are designed to scale in networks of a few hundred nodes. They rely on state concerning all links of the network or links on the route between a source and a destination. This may result in poor scaling properties in larger mobile networks or when node mobility is high. Using … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,733 accessesView PDFCite
Research ArticleOpen accessIn the abstractFormal Analysis of Fault-tolerant Algorithm in the Time-triggered ArchitectureAliouat Zibouda, Aliouat Makhlouf, Batouche ChawkiTime-Triggered architecture (TTA) provides a computing infrastructure for the design and implementation of dependable distributed systems. The core building block of the TTA is the communication protocol TTP/C. This protocol has been designed to provide no faulty nodes. TTP/C integrates a set of fault-tolerant services like: message transmissions, clocks synchronization and Group Membership Protocol (GMP). The GMP protocol ensures that … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,647 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Mean-Variance Portfolio Optimal Under Utility PricingHürlimann WernerAn expected utility model of asset choice, which takes into account asset pricing, is considered. The obtained portfolio selection problem under utility pricing is solved under several assumptions including quadratic utility, exponential utility and multivariate symmetric elliptical returns. The obtained unique solution, called optimal utility portfolio, is shown mean-variance efficient in the classical sense. Various questions, including conditions for complete … …Journal of Mathematics and Statistics, Vol. 2, Issue 4 · 31 Dec 2006 · 6,172 accessesView PDFCite

Research ArticleOpen accessIn the abstractInterventions and Patterns of Risk in Adolescent HIV/AIDS PreventionRobert M. Malow, Rhonda Rosenberg, Geri Donenberg, Jessy G. DévieuxMid-way through the third decade of experience in preventing HIV/AIDS among adolescents, behavioral interventions and outcomes for high risk subgroups have generated evidence extremely instructive for navigating future priorities in reducing transmission risk behavior. Youth who abuse alcohol or drugs, who are detained or incarcerated, or have mental health co-morbidity such as externalizing disorders, represent the most significant challenge to … …American Journal of Infectious Diseases, Vol. 2, Issue 2 · 30 Jun 2006 · 7,281 accessesView PDFCite
Research ArticleOpen accessIn the abstractStochastically Simulating Low Morale - A Risk Factor Effect on Risk ManagementP. K.A. Suri, Rachna SoniOne of the proposed purposes for software process simulation is the management of software development risks, usually discussed within the category of project planning and management. However, modeling and simulation primarily for the purpose of software development risk management has not been explored and is quite limited. This study describes an approach to simulate Low Morale - a risk factor, … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Analysis and Design of the Enhanced Firewall for Intranet SecurityU. K. Singh, A. K. Ramani, N. S. ChaudhariIntranet often employ an Internet firewall to mitigate risks of system penetration, data theft, data destruction and other security breaches. Conventional Internet firewalls impose an overly simple inside vs. outside model of security that is incompatible with many business practices that require extending limited trust to external entities. Additionally, firewall security perimeters are somewhat weak: they provide no protection from … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,709 accessesView PDFCite
