With the frantic pace of the virtual reality technology, emerging applications such as virtual campus offer the potential to change the nature of information dissemination, particularly in the distance taught and learning arena. This paper develops a web-based multi-user virtual campus for distance learning system, more than a traditional campus, which is an interactive model with fully immersive...
Assembly related conflicts arising from collaborative product development process severely affect the downstream design and manufacturing activities. A collaborative approach to assembly sequence decision under distributed environment is presented. The product assembly is firstly decomposed into a hierarchical structure tree using an assembly representation based on connectors. The substructures are...
Internet traffic has been proven to be long-tailed and often modeled by lognormal distribution, Weibull or Pareto distributions theoretically. However, these mathematical models hinder us in traffic analysis and evaluation studies due to their complex representations and theoretical properties. This paper proposes a hyper-Erlang model (mixed Erlang distribution) for such a long-tailed network traffic...
