This paper presents the development of an e-learning system for language learning and teaching. This system is characterized by its interactivity and socialization, constant support and immediate assessment of learners' linguistic performance. These distinguishing pedagogical features played an important role in the system development process. Aspects concerning the choice of the methodology, the...
This paper proposes an IPv6-based hierarchical middleware architecture for an efficient control of home devices on a global network from anywhere. This architecture can be adopted by mobile and home devices for smart home control.
The programmable network envisioned in the late 1990s within standardization and research for the Intelligent Network is taking another attempt to come into reality using IP-based Next Generation Networks (NGN) and Application Programming Interfaces (API) for open developer access. Adopting technical concepts of providing high-level APIs for open service access from the Internet and World Wide Web...
This paper attempts to activate a large scale shopping streets (shotengai) using Internet technique. A new web architecture is made for activation of shotengai, which is a typical Japanese shopping streets in the city and towns. Recently, decline of shotengai is a serious problem by development of shopping centers. "Osu" is one of the most famous shotengai in Nagoya, Japan, which includes...
Current theories and systems do not satisfy the requirements of P2P streaming on Internet in aspects of large scale, high quality and low cost. The transmission model of overlay network is the key factor. This paper proposes Regular Structured Model for P2P streaming including overlay network theory and management mechanisms. We developed ClusterStream a high service quality streaming system based...
The development of web 2.0 increases the call for agile and simple Business process support. SOA (Service oriented Architecture) provides companies with a new model to build their IT applications around their business processes and combine them dynamically and flexibly with the services of partner companies. In this open and distributed context, it is required to implement an appropriate security...
With the maturity of SOA and rapid development of Internet, a new type of software delivery mode named SaaS (Software as a Service) which provides the customers functionalities needed arises. It saves the cost of IT operation and suits to the small to medium firms very much. Ecommerce has grown extraordinarily nowadays with widespread Internet usage. In order to make trades more convenient and faster,...
The steady drumbeat of Cloud as a disruptive influence for Infrastructure Service Providers (ISP's) and the enablement vehicle for Software As A Service (SAAS)providers can be heard loud and clear in the industry today. In fact, Cloud is probably at the peak of the hype curve, and already there are identified challenges associated with effective deployment for business critical applications (so called...
Wireless sensor networks (WSNs) have many applications in home and industrial automation, and the management and integration of WSNs into Internet and IP-based networks is still getting tremendous interesting. This paper presents a micro SOA-model as part of a 4-layered, SOA-based architecture targeting resource-constrained devices with 48 KB of ROM and 10 KB of RAM. The key idea in this model is...
The geographical knowledge-informed digital gazetteer service (KIDGS) is a standard web service that provides unified XML-based access interfaces for various applications. In order to solve the problem of the raising data storage crabbed from millions of web pages and increasing query efficiency requirements for different levels of requests, we analyze the characteristics of cloud computing application...
In a Sensor Web environment, sensors are heterogeneous. The Sensor planning service offers a standardized interface for the control of sensors and simulations. But some complex sensors like satellite need midterm or long-term action to response a given task, so, adding asynchronous support in SPS is necessary. The workflow description language can chain asynchronous web service together while it has...
To address the serious problems in e-commerce based on traditional 2D image-word, the author introduced Web3D, Flex and SSH technologies into e-commerce, presented “3D Virtual Reality & Flex” Web architecture for e-commerce, researched mechanisms of their architectures, and implemented their integration and communication & interaction: Flex and Struts2 via XML, Flex and Spring & Hibernate...
Availability of enormous processing power and immense storage capacity drive Cloud computing. Information industry oracles like Google and Microsoft are delivering their next generation of products through Cloud. With the success of Amazon Cloud computing service everyone is laying on line to adopt it. Increased processing capabilities of enterprise servers do not mean that hosted services can handle...
We describe an access control model that has been implemented in the web content management framework “Deme” (which rhymes with “team”). Access control in Deme is an example of what we call “bivalent relation object access control” (BROAC). This model builds on recent work by Giunchiglia et al. on relation-based access control (RelBAC), as well as other work on relational, flexible, fine-grained,...
In this paper, are presented some possibilities for application of an algebraic method which handles XML hierarchical data structures and makes faster the XML search mechanism. The article briefly presents the concepts of Web Services, Service-Oriented Architecture and other modern software paradigms for organization of the processes over internet. The accelerating techniques for XML navigation through...
Average information workers spend most of their time for searching, analyzing, reformatting and consolidating information. The recent advent of service-oriented architectures (SOA) built on Web services is a first attempt to streamline respectively automate those tasks in order to increase productivity. SOAP-based services work well within a company and are thus mainly used to for the integration...
A remote laboratory aims to provide access to remote lab equipment over the internet. The design and development of the client software is subject to various requirements. In this paper we discuss these requirements and propose solutions. Implementations are demonstrated for some remote experiments developed in the ERRL project. An XML format for experimental results is proposed as an attempt towards...
As the internet developing, web-based applications are increasingly popular in service-oriented architecture. Web service has XML support, which is the most suitable technology to achieve service-oriented architecture. Web service is essentially an interface which enables the isolations between different sites to communicate with each other. In this paper, based on .NET platform for web service and...
The technological impact of the Internet gave birth to telemedicine that provides both the digitalization of patient's medical records, and the coordination between different healthcare actors. Work in this domain has shown that the standard XML is one of solid supports for the specification of the structure and of the semantic of clinical information, especially XML also ensures publishing medical...
In this paper, we describe a practical realization of an Internet-of-Things (IoT) architecture at the University of Padova, Italy. Our network spans the floors of different buildings within the Department of Information Engineering, and is designed to provide access to basic services such as environmental monitoring and localization to University users, as well as to manage service access based on...
