The absolutely necessary goods distribution and human transfers are polluting and damaging the environment and new solution should be envisaged; the conflicting strategies to adopt new types of environment friendly transportation while maintaining operative the more economically convenient, but largely … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 8 Sep 2017 · 7,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurvey of Frontier Technologies and Approaches to Enable Humans-Mars Both Safe and AffordableDennis Meyer BushnellFrontier technologies and systems that could reduce costs and improve human health and safety for human missions to Mars. Overall cost reductions increase funding opportunities for addressing serious radiation and reduce gravity health impacts for human-mars class missions. Major cost reduction/health improvement opportunities include fast transit via either starship due to low-cost chemical fuels in space, or high thrust electric … …Journal of Aircraft and Spacecraft Technology, Vol. 8, Issue 1 · 13 Nov 2024 · 7,606 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Policy for Path Selection in Dynamic Source Routing Protocol for Mobile Ad-Hoc NetworksRagb O.M. Saleh, Md Yazid Mohd Saman, M. Nordin A. RahmanIn standard DSR protocol, nodes automatically discover and maintain the routes in the network by storing source routes, discovered dynamically on-demand. They maintain route caches that contain the source routes which the node is aware of. Entries are continually updated when new routes are learned and reorder the cached routes according to the traditional shortest path policy. The problem with … …Journal of Computer Science, Vol. 9, Issue 5 · 17 May 2013 · 6,216 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Route Shortening and Route Repairing Mechanism for Mobile Ad Hoc NetworksS. Revathi, T. R. RangaswamyProblem statement: Ad hoc Networks are wireless networks without any fixed infrastructure. The network topology changes frequently and unpredictably due to the random movement of the nodes. The Ad Hoc on Demand Distant Vector Routing (AODV) protocol works in a dynamic fashion, by establishing a route on demand and continues that route until it breaks. Due to the changing network … …Journal of Computer Science, Vol. 8, Issue 8 · 11 Jul 2012 · 7,068 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneralization of Boolean Functions Properties to Functions Defined over GF(p)Saad Elmansori, B. E. EsamProblem statement: Traditionally, cryptographic applications designed on hardware have always tried to take advantage of the simplicity of implementation functions over GF(p), p = 2, to reduce costs and improve performance. On the contrast, functions defined over GF(p); p > 2, possess far better cryptographic properties than GF(2) functions. Approach: We generalize some of the previous results on cryptographic Boolean … …Journal of Computer Science, Vol. 8, Issue 6 · 13 Mar 2012 · 7,436 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Polypropylene Fibers on the California Bearing Ratio of Air Cured Stabilized Tropical Peat SoilBehzad Kalantari, Bujang B.K. Huat, Arun PrasadProblem statement: Peat soil is well known to deform and fail under a light surcharge load and is characterized with low shear strength, high compressibility and high water content. With the rising demand from the construction industry, utilization of these soils is required and suitable technique needs to be found out for stabilizing them. Approach: Model study had been carried … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractEngineering of Ground for Liquefaction Mitigation Using Granular Columnar Inclusions: Recent DevelopmentsA. Murali Krishna, M.R. MadhavProblem statement: Liquefaction was the most hazardous damage during an earthquake. Ground improvement techniques were employed to mitigate liquefaction hazards. Most common methods to improve engineering properties of soils are densification, reinforcement, grouting/mixing and drainage. Among various remedial measures available, installation of columnar granular inclusions is the most widely adopted method for liquefaction mitigation. Approach: Columnar granular inclusions function as … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 7,736 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation on Geomechanical Properties of Tropical Organic Soils and PeatBujang B.K. Huat, Afshin Asadi, Sina KazemianProblem statement: Organic soils and peat were believed to be geotechnically problematic due to their very high compressibility, very low shear strength and difficult accessibility. Although conventional soil mechanics theory could be applied to the soils, it was found that important anomalies existed which required special considerations. Correlations between geomechanical parameters for the soils were known to be important for … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 10,172 accessesView PDFCite

Research ArticleOpen accessIn the abstractBoosted Regression Estimates of Spatial Data: Pointwise InferenceMarco Di Marzio, Charles C. TaylorIn this study simple nonparametric techniques have been adopted to estimate the trend surface of the Swiss rainfall data. In particular we employed the Nadaraya-Watson smoother and in addition, an adapted-by boosting-version of it. Additionally, we have explored the use of the Nadaraya-Watson estimator for the construction of pointwise confidence intervals. Overall, boosting does seem to improve the estimate as … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,349 accessesView PDFCite
