Ubiquitous computing and universal network connectivity have given rise to expectations of building a Digital Society, where many aspects of business and social activities may be accomplished by remote participants. Intelligent, context-aware, and workflow-centric collaboration is an essential prerequisite to fulfill that expectation. EkSarva is a framework, which enables realization of such collaborations in diverse domains. This is accomplished by identifying the key concepts and their inter-relationships (dubbed the PPP/SST paradigm), which form the foundation of this framework. The key concepts include: (a) Project, (b) Person, (c) Place, (d) Signal, (e) Situation, and (f) Transcript. This paper describes how these concepts collectively can give rise to an intelligent collaboration environment.

Algorithm visualizations graphically illustrate how algorithms work. In prior ethnographic studies of a computer science course in which students were required to construct and present their own algorithm visualizations, we observed that visualizations based on storylines tended to stimulate increased audience interest and involvement. This observation, coupled with the empirical research that substantiates the value of stories as mnemonic devices, raises an interesting research question: Do visualizations with storylines actually help students remember the procedural behavior of an algorithm better than visualizations that do not involve storylines? To investigate this question, we conducted an experimental study that compared the memorability of algorithm descriptions involving differing degrees of spatial and verbal embellishment. The study failed to detect significant differences. We reflect on our lack of significant results, and suggest two alternative paths for future research into the value of story-based algorithm visualization

Donghua University Shanghai 200051he totally coded method (TCM) reveals the same objective law which governs the gain calculating for signal flow graph as Mason formula does. This algorithm is carried out merely in the domain of code operation. Based on pure code algorithm it is more efficient because figure searching is no longer necessary. The code-series (CS) which are organized from node association table have the holoinformation nature so that both the content and the sign of each gain-term can be determined via the coded method. The principle of this method is obvious and it is suited for computer programming. The capability of the computeraided analysis for Switched Capacitor (SCN) can be enhanced.

To reduce speech recognition error rate we can use better statistical language models. These models can be improved by grouping words into word equivalence classes. Clustering algorithms can be used to automatically do this word grouping. We present an incremental clustering algorithm and two iterative clustering algorithms. Also, we compare them with previous algorithms. The experimental results show that the two iterative algorithms perform as well as previous ones. It should be pointed out that one of them, that uses the leaving one out technique, has the ability to automatically determine the optimum number of classes. These iterative algorithms are used by the incremental one. On the other hand, the proposed incremental algorithm achieves the best results of the compared algorithms, its behavior is the most regular with the variation of the number of classes and can automatically determine the optimum number of classes.

QoS solutions for Core Internet Networks require that we pay special attention to scalability, as they deal with a lot of flows and demand many resources. In this paper, integrated solutions from the physical layer (SDH/SONET and DTM) to the IP layer (IntServ and DiffServ) are analysed and proposed, concentrating not only on scalability, but also on QoS guarantees.
