Study on the Design Scheme of Vehicle Flow Lines in Unilateral Agglomerative Open Service Area

In recent years,with the introduction of the strategy to strengthen the country’s transportation infrastructure and the continuous implementation of new economic development models such as integrating transportation with tourism,various open service areas integrating highway service areas with local tourism have emerged nationwide.Examples include the Yangcheng Lake service area in Jiangsu and the Lengshui service area in Chongqing.This paper focuses on the design example of the Dazu Stone Carving service area on the Chongqing section of the Yurong Expressway,comprehensively considering factors such as construction scale,terrain conditions,and local urban planning.It analyzes and studies the traffic flow design of unilateral agglomerative open service areas around two vehicle traffic conversion links:between the main expressway and the service area,and between the service area and local roads.The aim is to provide a case study reference for similar projects.

OPENING UP NEW PROSPECTS FOR CHINA'S SERVICE TRADE LED BY TOURISM

Since the launch of the reform, China’s service trade has been growing at a much faster speed compared to that of the rest of the country’s economy and world trade. In developing commodity trade, we are also engaged in technology trade, service trade and international investment, making efforts to achieve fusion and mutual promotion. Now, we are speeding up the opening

Resource management framework for manufacturing grid

Based on open grid service architecture (OGSA) and Globus Toolkit 3. 0 (GT3), a manufacturing grid (MG) is proposed to realize resource sharing and collaborative working among manufacturing enterprises. Nevertheless, resource management in MG is much more complicated than that in other grid applications due to the geographically distributed manufacturing resources, which range from CAD, CAPP and CAE to various kinds of machine tools. With the interaction of manufacturing grid information service (MGIS, developed by ourselves) and globus resource allocation manager (GRAM, provided by GT3), a resource management framework is presented to perform the functions of resource encapsulation, registry, discovery and monitoring. Furthermore, the application architecture and an example are depicted to illustrate the utilization of the resource management system.

在WTO框架内加快南京服务业对外开放对策研究

This paper analyses the recent international trends and rules of opening service industry. Then with the discussion of the status of Nanjing’s service industry, the paper argues its marketing competitiveness is still low and its openness doesn’ t satisfies the WTO’s requirments. Finally, the paper focuses on the opening strategies of Nanjing service industry, including Nanjing’s policy targets, basic principles, and detailed measures for main service sectors.

A Scalable Policy and SNMP Based Network Management Framework

Traditional SNMP-based network management can not deal with the task of managing large-scaled distributed network,while policy-based management is one of the effective solutions in network and distributed systems management.However,cross-vendor hardware compatibility is one of the limitations in policy-based management.Devices existing in current network mostly support SNMP rather than Common Open Policy Service(COPS)protocol.By analyzing traditional network management and policy-based network management,a scalable network management framework is proposed.It is combined with Internet Engineering Task Force(IETF)framework for policy-based management and SNMP-based network management.By interpreting and translating policy decision to SNMP message,policy can be executed in traditional SNMP-based device.

A great leap forward:how to choose strategies and policies to promote the Chinese service industry

The development level of the service industry is an important indicator to measure the level of economic and social development and the optimization of the economic structure.As the status of the service industry in the Chinese economy is increasing,it is playing a more important role in boosting economic growth,promoting employment and adjusting the economic structure.China is facing an unprecedented opportunity to develop its service industry.There is vast potential for the future development of producer services,consumer services,and new service industries.Development of a modern service industry should be oriented toward strategies to foster industrial convergence and industrial clustering,boosting creativity and openness.The authorities need to abolish over-regulations on finance,taxation,investment,land and talents,facilitating the development of service industry.

Toward an SCA-OSGi based Middleware for Radio Frequency Identification Applications

The radio frequency identification (RFID) technology progressing is becoming a increasing interest in several application areas. To accommodate diverse and changing requirements from applications,RFID middleware should be reconfigurable. However,current RFID middleware is limited in its ability to support reconfiguration. To solve this problem,we adopt the service-oriented component-based approach in building the middleware. Component-based design enables decomposition of middleware functionality and is easier than the current one to manage and modify the structure of the middleware both statically and dynamically. Applying service-oriented architecture (SOA) can further reduce the coupling between components and external software and ease the integration between middleware and applications. We propose a two-layered service component architecture (SCA) open service gateway initiative (OSGi) component model so as to enable reconfigurability. Based on the proposed component model,we build a standard-based RFID middleware-SCA-OSGi based RFID middleware (SORM) which supports flexible deployment topologies and reconfigurability. The design and implementation details of SORM are illustrated.

A Solution of Grid Computing Flow Using MDA Methodology

This paper presents an approach to build a flow of grid services named GFlow. This approach converts all of the services＇ interfaces in globus toolkit 3 into platform independent model format. The conversion uses eclipse modeling framework plug-ins and graphical editing framework plug-ins to parse the models into platform specific models, which are responsible for implementation of grid services＇ clients and servers and their automatic deployment. This paper emphasizes on design method, which uses model drive architecture, and design process, which uses model-view-control.

Design and Implementation of NAREGI SuperScheduler Based on the OGSA Architecture

NAREGI is a 5-year Japanese National Grid Project during 2003--2007, whose chief aim is to develop a set of grid middleware to serve as a basis for future e-Science. NAREGI also aims to lead the way in standardization of grid middleware, based on the OGSA architecture. Its super-scheduler is based on the proposed OGSA-EMS Architecture, in that it becomes the first working implementation that implements the documented component relationships within the OGSA-EMS architecture document v.l.0. Through the efforts and experience in the design and implementation, it has been confirmed that the documented OGSA-EMS architecture is quite feasible, but will require significant amount of refinement and speed improvements to finalize its detailed specifications. The super-scheduler also supports co-allocation across multiple sites to support automated execution of grid-based MPIs that execute across machines. Such a resource allocation requires sophisticated interactions between the OGSA-EMS components not covered in the current OGSA-EMS architecture, some of which are non-trivial. Overall, job scheduling with OGSA-EMS has proven to not only work, but also that its job allocation and execution time is within reasonable bounds.
