Recently an integrated multiplatform system aiming at offering travel service over several communication channels is under development. A set of cooperating systems in completely different platforms will work together to provide integrated services to the clients anywhere and anytime. The structure, communication environment, some special issues and implementation of the system are discussed in the paper.

Mobile computing system using mobile Web Services now supports advanced methods for application integration through the Internet at distributed computing environments. Mobile Web Services on mobile networks is the foundation for ubiquitous healthcare that gives patients better medical services anytime and anywhere. However, available existing web contents are mainly used for desktops on wired networks, but are not yet compatible with mobile Web Services. In this paper, we suggested the cooperative mobile healthcare information support system. The designed system can achieve the advanced inquiring manner of medical information for collaborate diagnosis at both desktop and mobile machines, and also afford to support wider accessibility of users over wireless and wired network environments.

The communication cluster servers require many key technologies in an information integration platform. In order to improve dependability, scalability, and other QoS features, we design a system structure to meet these requirements. The resource sharing and remote utilizing are applied to resolving the dynamical resource dispatch and the tasks distribution. The thread model and mechanism of the thread pool in the Non-blocking Input/Output (NIO) are created which include a case trigger mechanism. The system successfully resolves thousands of terminals connected to the information integrated platform. Messages, files, data, and other information can transport among the platform, the clients and the terminals.

This paper proposes a novel information sharing system architecture to integrate the distributed and various WSNs together to make their resources more sharable, based on Peer to Peer (P2P) network and the technologies of web service and middleware.

Available ontologies of different information sources are often heterogeneous. It is critical to find an effective solution for many problems of collaborative environment. This paper presents a novel approach to completing heterogeneous collaboration environment that offers a means for developers to describe context essentials with intent-extent of context, to construct context facades using ontological slice, and to implement mediating collaboration based on the context facades.

Based on Data warehousing concept Personal Window Knowledge Capsule is Designed. This knowledge capsule has learning, perception Inference, knowledge structuring and Knowledge retrieval functions. Especially it provides multiple aspects of personal windows assembling the selected necessary functional module and personal viewpoint of Knowledge network flexibly. We applied this system to the virtual memory and test with sample data.

In order to meet the requirements of massive data processing and high quality of service, a WebGIS(Web Geographic Information System) cluster system has been developed which has the capability of balancing resources between servers. This cluster system includes three parts: a load balancer, a GIS server cluster, and a database of spatial and geographic information. The strategy of dynamic dispatch and the algorithm of adaptive load balancing service are presented in the paper.

Microsoft Visio is one of the most prevalent commercial single-user graphic editing systems, which can be used to create a wide variety of business and technical drawings. It is desirable to leverage single-user Visio system for multi-user real-time collaboration. One feature that distinguishes Visio from other graphic editing systems is that , a type of constraint, are defined in Visio to express the attributes of each graphic object, and the relationship between different Visio graphic objects. The ability to describe shapes with constraints opens many possibilities for making shapes behave in complex and sophisticated ways, but satisfying constraints in the presence of concurrency in collaborative systems is a challenge. In this article, we introduce a collaborative Visio system, called CoVisio, which enables a group of users to view and edit the same Visio documents at the same time from different collaborating sites. The methods applied to develop CoVisio are generic and can be adopted to leverage other single-user systems that support constraints, such as Microsoft Excel, for multi-user collaboration.

The paper is devoted to application of formal concept analysis and collaborative design in shipbuilding. Sourcing and shoring strategies of a Norwegian multinational design company is illustrated by a concept lattice.

Nowadays, collaborative product development has become a strategic necessity to develop high quality products at low cost and with quick response time to market demand. Past decades have seen significant advances to collaborative product development. However, Enterprises are still confronted with some problems. Firstly, the research in strategic level of collaborative product development is lacking. There are no formal processes and models for collaborative product development. On the other hand, the full alignment between information system and collaborative business is still missing. The information system cannot adapt to the fast changed business. This paper aims to provide the strategy and reference business model for collaborative product development. And then, to support the implementation of strategy and model, a workflow and web service based engineering collaboration portal is developed. The workflow is used to model and execute the collaborative product development processes, and the web service is the implementing technology of the portal. The combination of workflow and web service can fit the gap between business and information system and achieve on-demand business.
