Simulation of Tsunami Impact on Water Mass Variations Based on Pareto Optimization by Maged Marghany in Modern Approaches in Oceanography and Petrochemical Sciences in Lupine Publishers

There is no query that the tsunami performs remarkable roles to alternate the physical properties of the ocean through mixing turbulent approaches. This study has proposed and demonstrated a new approach to retrieve the water mass pattern from remote sensing data. This examination has proposed and shown another way to deal with recovering water mass example from remote detecting information. The MODIS satellite information is procured pre, during and boxing day 2004. In this way, GA delivered another equation to recover the water mass by upgrading mistakes because of overcast spreads, and SST and SSS straight calculation executions. The investigation demonstrates that GA can diminish the blunder of recovering ocean surface thickness with ±2.87kg/ m3. Further, during and post-tsunami 2004, the coastal waters are commanded by most extreme density estimation of 25.8kg/m3 which initially organized along Aceh coastal waters. It can be alleged that GA can be utilized to recover water mass qualities utilizing MODIS satellite information.

A Study on the Soundness of Parent Rocks in Sri Lanka (TCEIA) - Lupine Publishers

A Study on the Soundness of Parent Rocks in Sri Lanka (TCEIA) - Lupine Publishers

Studies on the engineering properties of different rock types provide a prior knowledge on the quality of such rock types as well as potential locations of suitable sources for the industry. The property "soundness" of a material measures the tendency to split into pieces similar to physical weathering during expansion and contraction processes within it. This soundness varies according to the type of minerals in a rock and its' origin. If rocks are using for aggregates for concrete or other applications the estimation of their soundness is necessary. With the aim of that, fresh rock samples of different rock types were collected from quarries and exposed rocks in different locali-ties in Sri Lanka to study the variation of soundness property in different rock aggregates. Samples were tested in the geotechnical engineering laboratory using sodium sulfate solution according to the Standard Method ASTM C88-99a. The rock types were Chranockite/charnockitic gneiss, garnet/hornblende/biotite gneiss, Microcline/Granitic gneiss, Garnet/biotite gneiss, Marble, Hornblende biotite gneiss, Quartzite, pegmatite, pink granite and Miocene limestone. Accordingly charnockite/ charnockitic gneiss shows the lowest loss of weight percentage as the highly sound rock for aggregates. Miocene limestone is the highly unfavorable rock.
