The goal of this study was improvement of sandy soil using a combination of polystyrene foam container waste and Portland cement. For this purpose, Babolsar sand was used as the base soil. Strips of disposable polystyrene foam container waste in “chips” of 50 ´ 5 mm and 50 ´ 10 mm were added to the soil at 0.0%, 0.1%, 0.2% and 0.3% by weight along with 3% Portland cement at a relative density o...
It is important to recognize that several years of hands on experience are required for one to become a true test expert. However, it is critical to ensure that students are equipped with the skills that will make them successful designers when they leave their academic institutions. Fundamentals of VLSI design and testability would provide them with a solid foundation to build upon going forward.
The importance of decreasing the cost of soil structures due to the budget constraints makes engineers avoid handling large volumes of soil, thus making maximum use of local materials. Soil performance change in order to improve engineering applications of soil is called soil stabilization. Soil stabilization methods can be mechanical, electrical, thermal, chemical, etc. Gypsiferous soil includ...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
Wall-bounded flows at high Reynolds number are characterized by high rates of shear at the walls. Resolving the flow near the wall, is critical to correctly reproducing the turbulence. In the present paper, we show that the accurate prediction of spatially varying wall shear stress requires additional near-wall resolution for large eddy simulation. We also demonstrate the advantage of the use o...
A theoretical approach proposed in Phys. Rev. E 66, 066305 (2002) is developed further to investigate formation of large-scale coherent structures in a non-rotating turbulent convection via excitation of a large-scale instability. In particular, the convective-wind instability that causes formation of large-scale coherent motions in the form of cells, can be excited in a shear-free regime. It w...
A theoretical approach proposed by Elperin et al. Phys. Rev. E 66, 066305 2002 is developed further to investigate formation of large-scale coherent structures in a nonrotating turbulent convection via excitation of a large-scale instability. In particular, the convective-wind instability that causes formation of large-scale coherent motions in the form of cells, can be excited in a shear-free ...
This paper reports an experimental investigation of the characteristics of local dissipation length-scale field in turbulent (round and square) jets with various jet-exit Reynolds numbers. Results reveal that the probability density function (PDF) of , denoted by Q(), in the central fully-turbulent region, is insensitive to initial flow conditions and the departure from anisotropy. Excellen...
