Research ArticleOpen accessIn the abstractStrength and Ductility of Randomly Distributed Palm Fibers Reinforced Silty-Sand SoilsS.M. Marandi, M.H. Bagheripour, R. Rahgozar, H. ZareThis paper investigates the resultant strength and ductility behavior when randomly distributed palm fibers are used to reinforce silty-sand soils. The composite soils were tested under laboratory conditions and examined for unconfined compression strength (UCS), California Bearing Ratio (CBR) and compaction test. The results indicated that; the maximum and residual strengths, orientation of surface failures, ductility and the stress-strain relationship … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 8,864 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeterogeneous GPRS-WLAN Integration Based on Ad-Hoc NetworksS. LouvrosIn heterogeneous microcellular networks like 802.11(WLAN)-GPRS, users can roam around through vertical handoffs. The major problem in heterogeneous networks is that they support different QoS requirements and the users suffer sudden changes in data rates. This study proposes certain routing algorithms to extend the service time of mobile handsets in the wireless network with higher available data rate, thus improving … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 6,540 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethods of Utilizing Tropical Peat Land for Housing SchemeYouventharan Duraisamy, Bujang B.K. Huat, Azlan A. AzizThis paper discusses some of the methods and recent technologies in utilizing cheap marginal land such as tropical peat for housing scheme. Buildings on peat are usually suspended on piles, but ground around it may still settle. Therefore a suitable method of construction should be tackle to overcome serious problem such as localized sinking and slip failure, massive primary and … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,674 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 · 7,121 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmpirical Analysis: Business Cycles and Inward FDI in ChinaQiyun Fang, Yao LiuIt is well-known that the current speeding-up of globalization has been, on one hand, spreading macro economic effects around the world, while, on the other, fueling firms' activities of crossing national borders. Then, are there any links between these two influences? In this paper, we chose China as our subject, to try to clarify it. A set of models for … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 6,836 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Axisymmetric Thermal Plume between Vertical PlatesJamil Zinoubi, Adel Gammoudi, Taoufik Naffouti et al.This investigation analyses the turbulent structure of a thermal plume created by a heated disk, evolving between vertical plates. The objective of the study was to understand the development mechanisms of this buoyancy driven flow. The analysis of the average and the fluctuating fields of the temperature as well as the flow visualisation show the existence of three different zones. … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Modeling Approach for Collision Avoidance in Robotic SurgeryReza Ramezanifard, Javad Dargahi, Siamak Najarian, Farhad Tabatabai GhomsheWe present a new system that can be used in combination with an array of ultrasonic piezoelectric sensors and has application in surgical navigation procedures. Using the proposed assembly, the maneuverability of the surgical tools can be enhanced and the incidence of potentially damaging contact with non-target tissue can be reduced. The emphasis of our work was based on controlling … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 6,798 accessesView PDFCite
Research ArticleOpen accessIn the abstractAd Hoc Mobile Wireless Networks Routing Protocols - A ReviewGeetha Jayakumar, G. GopinathMobile ad hoc networks(MANET) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self organize into arbitrary and temporary ad-hoc network topologies, allowing people and devices to seamlessly internet work in areas with no preexisting communication infrastructure e.g., disaster recovery environments. An ad-hoc network is not a new one, having been around in various forms … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 115,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Characterization of Clinker’s Microstructure at Different Temperature Zone during Cement ProductionMohd Sobri Idris, Khairul Nizar Ismail, Shamsul Baharin Jamaludin et al.Temperature is an important parameter for transformation of minerals in clinker during cement productions. It influences the formation of alite from belite during calcinations and clinkering processes. The result of microstructure shows that the formation of belite minerals started at temperature nearly 1200°C which is at calcinations zone temperature, followed by formation of α±-belite at higher temperature (around 1300°C), then … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,502 accessesView PDFCite
Research ArticleOpen accessIn the abstractPetrology and Origin of Ultramfic Xenoliths from North Eastern Jordan VolcanoesHassan Al-Fugha, Mazen AL-AmairehThe distribution of major, minor and trace elements in the Cenozoic alkali basalt from north-eastern Jordan indicates a homogeneous lava flow from a mantle source. These basaltic rocks contain abundant upper mantle xenoliths (spinal lherzolite, harzburgile and olivine- websterite). Theses xenoliths contain olivine, orthopyroxne, clinoporoxene and a few amounts of spinal. Their mineral assemblages, chemistry, texture and major elements abundances … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,016 accessesView PDFCite
