Research ArticleOpen accessIn the keywordsStudy of the Permeability of Foam Conditioned Soils with Laboratory TestsLuca Borio, Daniele PeilaProblem statement: EPB tunneling requires that the excavated soil has a plastic and pulpy behavior to be able to apply a stabilizing pressure to the face, but it should also be impervious to counteract filtration forces that could develop ahead of the face. The evaluation of this parameter in granular soil, before and after conditioning, is therefore of key importance … …American Journal of Environmental Sciences, Vol. 6, Issue 4 · 31 Aug 2010 · 8,459 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMost Used Rock Mass Classifications for Underground OpeningAl-Jbori A’ssim, Zhang Y. XingProblem statement: Rock mass characterization is an integral part of rock engineering practice. The empirical design methods based on rock mass classifications systems provide quick assessments of the support requirements for underground excavations at any stage of a project, even if the available geotechnical data are limited. The underground excavation industry tends to lean on empirical approaches such as rock … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,274 accessesView PDFCite

Research ArticleOpen accessIn the keywordsPhase Transition in Φ6 PotentialHatem WidyanScalar field theory with an asymmetric potential was studied at zero temperature and high-temperature for Φ6 potential. The equations of motion are solved numerically to obtain O(4) spherical symmetric and O(3) cylindrical symmetric bounce solutions. These solutions control the rates for tunneling from the false vacuum to the true vacuum by bubble formation. The range of validity of the thin-wall … …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 6,878 accessesView PDFCite
Research ArticleOpen accessIn the keywordsData Path Management Mechanism to Mesh Base Stations in WiMAXSahar Abdul Aziz Al-Talib, Noor Raad SaadallahThree options are popular today for design of wireless networks - Point-to-Point, Point-to-Multipoint and Mesh topologies. Worldwide interoperability of microwave access (WiMAX) is most often associated with the point-to-multipoint (PMP) topology. For some requirements, the configuration of the base stations (BSs) is aimed to be as mesh. Mesh offers a combination of point-to-point and point-to-multipoint capability by having each of … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 22 Mar 2019 · 7,972 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNonlinear Analysis of RC Box Culverts Resting on a Linear Elastic SoilDaniele Baraldi, Fabio Minghini, Enrico Tezzon, Nerio TulliniIn the analyses presented, the soil-structure interaction is accounted for by means of a FE-BIE approach, in which the structure is modelled with displacement-based beam finite elements, whereas the boundary between structure and substrate is described in terms of surface tractions by means of a boundary integral equation incorporating a suitable Green's function. This mixed formulation ensures full continuity between … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 8 Feb 2018 · 12,632 accessesView PDFCite
