    Abstract: To protect the privacy, sensitive information has to be encrypted before outsourcing to the cloud. Thus the effective data uct keyword search. Related works on searchable encryption emphasis on single keyword based search or Boolean keyword based search, and hardly work on sorting the search results. Our work focuses on realizing secure semantic se... Show More

    Abstract: In order to design a microstrip patch antenna at first the designer is to select the substrate material and it’s thickness. So, if the designer has a clear conception about the effect of changing substrate material and it’s thickness on the performance of the antenna, it will be easier to design an antenna. Appropriate selection of dielectric mater... Show More
