The proposed method has been tested on IEEE 30 bus system where the obtained results were found satisfactorily to a large extent that of reported earlier.

The above presented problem was solved on basis of efficient and reliable technique among all evolutionary based algorithms, the Differential Evolution Technique.

Since the mix design of self-consolidating concrete (SCC) differs from that of conventional concrete, mechanical properties of SCC may differ from those of vibrated concrete.

An experimental program was performed to evaluate mechanical properties of SCC used for precast, prestressed applications.

Abstract: Spatial Data Infrastructure (SDI) is the geographic data framework implementation of data, metadata, users and tools in terms of data infrastructure that are connected in interactive way to allow the flexibly and efficient use of the data. Our system will allow E-examinations to be taken securely under the supervision of invigilators and with subjective assessment in it, with instantaneous availability of results.

The results show that the compressive strength varied from 1.5N/mm2 to 6.5N/mm2 for the replacement levels at 48 days of curing. [5] BS1881; Part 3 (1992) Method for Determination of Density of partially compacted Semi-dry fresh Concrete, British Standard Institution.
