In this paper, we will discuss the techniques of building up a large scale prototype platform for collaboration on IP-based network, and summarize the structure of that platform. To solve the large-scale problem, we make performance analysis on key modules of the system. Based on the result, we provide a basic prototype platform which contains multimedia communication and basic data collaborati...

Conventional cluster validity techniques usually represent all the validity information available about a particular clustering by a single numbel. The display method introduced here uses images generated lrom the results of any prototype generator clustering algorithm to do cluster validation.

We describe work-in-progress prototypes of auditory displays for fuel efficiency driver interfaces (FEDIs). Although research has established that feedback from FEDIs can have a positive impact on driver behaviors associated with fuel economy, the impact of FEDIs on driver distraction has not been established. Visual displays may be problematic for providing this feedback; it is precisely durin...

The interworking language provides a graphical method for the description of synchronous interactions between system components. In this paper we give an overview of the language and discuss the prototype tool set which has been developed to support the use of interworkings.

During the last decades Intelligent Transportation Systems (ITS) have been attracting the interest of an increasing number of researchers, engineers and entrepreneurs, as well as citizens and civil authorities, since they can contribute towards improving road transport safety and efficiency and ameliorate environmental conditions and life quality. Emerging technologies yield miniaturized sensin...

This paper describes the development of OCPL (object conceptual prototyping language), an object±knowledge representation language. The language is based on CPL, conceptual prototyping language, developed at the Free University of Amsterdam. CPL has been extended to allow for the explicit representation of object-oriented constructs. These constructs include facilities for application system de...
