A concurrent engineering-oriented design database representation model (CE-DDRM) is introduced in this research for supporting various life-cycle aspects in concurrent design. In this model, concepts and behaviors of different design database modeling components, including entities, properties, relationships, tasks, and specifications, are defined at meta-class level. Design database is modeled...

Information technology has played an increasingly important role in engineering product development. Its influence over the past decade has been accelerating and its impact in the coming decade will undoubtedly be immense. This paper surveys several research areas relating to knowledge representation, capture and retrieval, which will have a growing influence on product development. Each of the...

United States industry spends billions of dollars as a result of poor interoperability between computer-aided engineering software tools. While ongoing standards development efforts are attempting to address this problem in today's tools, the more signi®cant demand in nextgeneration tools will be for representations that allow information used or generated during various product development act...

Nowadays networks require flexible dynamic group communication with the internet. When we develop these systems on multicast communication framework, various types of security threat occurs .As a result construction of secure group communication that protects users from intrusion and eavesdropping are very important. In this paper, we propose an efficient key distribution method for a secure gr...

The process of developing and making music with Ferin Martino, a piano-playing software algorithm has opened up a number of inquiries surrounding modern performance and creativity. Although it is relatively simple program, it is capable of much unique, expressive output that maintains a consistent style. Instead of constructing musical passages note by note, its musical character arises from it...

This paper outlines an ongoing research project on training, education and sharing of experiences among mobile people. The importance for professionals to continuously learn is widely recognized. Organizations in the new economy are dependent on organizational knowledge and competence. Mobile workers need alternative educational and knowledge development opportunities that are not restrained by...

With each successive generation of new educational technologies the dawn of a revolution in teaching and learning is heralded. There have been many such dawns in the last 30 years, during which the desktop computer and the Internet have been developed; but there have been similar dawns throughout the century film, radio, records, broadcast television, audio-tape, videotape, programmed learning ...

In this paper, we propose a new type of local binary pattern (LBP)-based feature, called Rotation Invariant Co-occurrence among adjacent LBPs (RIC-LBP), which simultaneously has characteristics of rotation invariance and a high descriptive ability. LBP was originally designed as a texture description for a local region, called a micropattern, and has been extended to various types of LBP-based ...

Network security is very important when sending confidential data through the network. Cryptography is the science of hiding information, and a combination of cryptography solutions with cognitive science starts a new branch called cognitive cryptography that guarantee the confidentiality and integrity of the data. Brain signals as a biometric indicator can convert to a binary code which can be...
