Steganography is the science of hiding a message signal in a host signal, without any perceptual distortion of the host signal. Using steganography, information can be hidden in the carrier items such as images, videos, sounds files, text files, while performing data transmission. In image steganography field, it is a major concern of the researchers how to improve the capacity of hidden data i...

Even though SQL has become widely accepted as a language for implementing relational database schemas and querying data, there are cases where its users experience the need for new language abstractions which would allow them to express data modeling and querying solutions in a clearer and simpler manner. This paper describes the idea of language extensions to SQL:1999 that come in form of inde...

Knowledge sharing behavior in virtual communities has long been an important area of research. Prior related research has primarily focused on relational virtual community (RVC) where knowledge sharing is regarded as a social exchange behavior, heavily depending on the social concerns such as reciprocity, identification and norms. The objective of our study is to investigate knowledge contribut...

Our future society will be different from that we have known in the last fifty years. Futurists foresee that in the near couple decades the world’s community will traverse through a period of rapid technological innovations that will change the foundations of society as we used to know it (Tapscott, 1997; Wallace, 1999; Borgmann; 1999). Changes will engulf all aspects of life (Gleick, 1999). Th...

The need of taxonomy is vital for knowledge sharing. This need has been portrayed by through-life engineering services/systems. This paper addresses this issue by repair process taxonomy development. Framework for repair process taxonomy was developed followed by its implementation. The importance of repair process taxonomy has been highlighted.
