As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...

the advantages and special characteristics of service oriented architecture and expansion of employing such architecture have brought security topics which are different in some cases from the security principles of traditional information systems. in this article our aim is the examination of various indices of security and the presentation of strategies for security in information systems by ...

the the main objective of this research paper is to present 3-d elasticity solution for free vibration analysis of elastically supported continuously graded carbon nanotube-reinforced (cgcntr) annular plates. the volume fractions of oriented, straight single-walled carbon nanotubes (swcnts) are assumed to be graded in the thickness direction. an equivalent continuum model based on the eshelby-m...

Two new techniques for multi-method dispatch are presented, both sufficiently general to apply to reflexive languages where methods and types can be added and removed at run-time. However, these techniques also apply to non-reflexive languages. One of the techniques operates by performing projections onto single-receiver dispatch tables, and thus benefits from existing research into single-rece...
