This paper discusses two approaches to enhance multi-site scheduling for grid environments. First the potential improvements of multi-site scheduling by applying constraints for the job fragmentation are presented. Subsequently, an adaptive multi-site scheduling algorithm is pointed out and evaluated. The adaptive multi-site scheduling uses a simple decision rule whether to use or not to use mu...
When a tunnel passes through weak soil with different conditions, or there is a thin layer of soil on top of the tunnel, the mass of soil or rock must be stabilized. In addition, an excavation method must be chosen and applied in order to control the amount of subsidence and convergence which are among the most significant factors in excavation a tunnel especially in urban area, since the soil ...
Phosphosulfonic acid as a multi solid site was easilyprepared from the reaction of ammonium dihydrogen phosphatewith chlorosulfonic acid in CCl4and for improved its catalyticactivity was supported nano Silica was extracted from husk ricecontains about 95% of Silica the size of extracted nano silica wasdetermined by SEM efficiency of this solid acid in four componentcondensation reaction of arom...
