In the last years, the Machine-to-Machine (M2M) communications evolved as one of the major trends shaping the development of services in the future Internet. The use of M2M technologies is rapidly increasing in different fields such as Health Care, Automotive, Energy, Consumer Electronics, manufacturing, security and Banking. With that rapid increase different protocols had been developed for M2M...
The development of a distributed simulation is a complex multidisciplinary task. It brings together computer science, systems engineering, operational research and a range of domain specific expertise. Thus, MATLAB introduced many distributed connectivity for developers, this connectivity with other environments requires some resources. In this paper, a new software connector is introduced to facilitate...
Services, such as Stack Overflow, offer a web platform to programmers for discussing technical issues, in form of Question and Answers (Q&A). Since Q&A services store the discussions, the generated “crowd knowledge” can be accessed and consumed by a large audience for a long time. Nevertheless, Q&A services are detached from the development environments used by programmers: Developers...
Contextual information are used to describe situations of entities (users and devices) and their interactions. Applications need such information in order to adapt their behaviour in response to changes in the entities context. In certain scenarios and in particular machine to machine, the integration of a large number of components makes the management of the generated contextual information a very...
The information development process of modern enterprise operation and management has been gradually transformed from the traditional centralized management to distributed, heterogeneous approach. To adapt this sort of requirement, the workflow management system has changed the original goal of creating the paperless office environment to the target of performing business processes automatically....
Designing and developing an effective web crawler is a challenging role in a large search engine. This paper proposes component based web crawler along with the indexer. The WebCrawler consist of crawler services and indexer services and realized as web services. The communication between the services is sent and received using XML, SOAP and WSDL. In the crawler service, the web pages are fetched...
IT-based services existing today, such as the ones supporting e-commerce systems or corporate applications, demand complex architectures to address enterprise-class requirements (high availability, vast user demand, etc.). In particular, most enterprise-class applications are multi-tiered and multi-node, i.e. composed of many independent systems with complex relationships among them. In recent years,...
This paper introduces the AJAX technology and how it works, and is mainly involved in the application of technology and the current situation. It discusses the limitations of using the traditional WEB method and advantages of using AJAX technology in the network test system, and it also gives a specific implementation of AJAX in the network test system. Using AJAX technology greatly reduces the pressure...
Urban micro-payment system, packet processing engines often have to deal with a number of concurrent operations, previously commonly used multi-threading technology to solve, but when the server processing tasks is characterized by lightweight, high frequency when the thread creation and destruction of the will be very frequent, thereby reducing system efficiency. In this paper, thread pool technology...
In the Brower/Server-based enterprise application system, a new web design approach based on Ajax technology is brought forth. Ajax and N-layer architecture are integrated in the development of college educational administration system, which results in better efficiency and maintainability. And particular realization method employing Ajax technology is presented for the generation tree module of...
With the promotion of e-government application system, the important effect of data exchange brings more and more concern and discussion. This paper proposes the data exchange system model which is composed of the data transmission services, data exchange adapter and task processors, aiming at data sharing and automatic data exchange application of GIS and other non-spatial data. We introduce XML...
With the rapid expansion of information in the network environment, it brings many challenges for information retrieval staff. It seems to be a pair of contradictions between the searchers' retrieval skill and the rapid expansion of information. On the one hand, the website developers must carefully consider arranging the retrieval key words in order to ensure the users to be able to meet their needs...
Aimed for the problem of Webservice needs to publish multiple services when the Webservice provides some business methods in the specific domain, a new design of Webservice is presented, which only publish one Webservice and the real business methods requested come from that server parsing client's message, instead of each business method is published as a WebService. This design makes the release...
As a main type of application structure, E-Business Application frame is used by many business companies. Because of the multifarious variation of working processes and rules, E-Business Application frame needs to constantly adapt to this kind of variation. Inspired by the Theory of Evolution, the author applies the Darwinian ideas to the software world and tries to make the applied system evolve...
The Internet site now is on the way to open, writeable, multimedia interactive platform, so as to adapt to the individual users' requirements of gradual high interaction. In order to meet this demand, AJAX (Asynchronous Javascript and XML) as a Web presentation layer technology, can build quick, flexible and dynamic Web applications. AJAX combines the techniques on CSS, javascript XHTML, XMLHTTP,...
Workflow Engine is the core component of Workflow Management System. According to the standards of Workflow Management Coalition, this paper uses Petri net as the principle model, divides the Engine system into five functional modules,adopts Java EE Distribute Object Computing technique,thread poll control mechanism and BeanShell script interpreter technique to give the design and implementation solution...
Interoperating heterogeneous simulation models and tools is becoming a necessity in today's cross-enterprise collaboration market. Nevertheless, simulation models and engines have evolved apart in many directions, making their interoperability extremely complex. We present the RESTful Interoperability Simulation Environment (RISE), which provides the means for interoperating simulation heterogeneous...
This paper focuses on the researches of Ajax technique and its application based on J2EE.The advantage and the disadvantage of using Ajax technique are analyzed through the experiments.Ajax technique is a comprehensive utilization of a set of Web2.0 core technology.The difference from the traditional Web working module is that Ajax technique adopts asynchronous to send request to server.The advantage...
Web based learning has grown particularly rapidly in the area of virtual experiment, while automatic marking of virtual experiment is still difficult. One reason is the semantic rule used in marking of virtual experiment. The other is the bottleneck of performance when used by a large amount of user. This paper proposes a complete solution for automatic marking of virtual experiment based on rules...
The Apache Ant presents certain characteristics that seem to make it suitable as a workflow language and engine. Features such as native dependency structured build targets make it easy to write declarative dependency-based workflows. We propose a framework enabling Ant build files (and its specifications) to be used as workflow scripts. Features like being semi structured and having standard specification...
