Distributed computing is a new paradigm in the field of resource sharing. Distributed computing seems as more promising in terms of request failure, security, flexibility and resource availability. It's main feature is to maintain the Quality of Service (QoS) provided to the end user in term of request processing power, request failure rate and many more. So resource management is important and maintaining...
Integrating large scale processing environments, such as Hadoop, with traditional repository systems, such as Fedora Commons 3, have long proved a daunting task. In this paper we show how this integration can be achieved using software developed in the SCAPE project. The SCAPE integration is based on four steps: retrieving the metadata records from the repository, reading the records and their references...
Recent years have seen a rapid growth in the number of virtual machines and virtual machine images that are managed to support infrastructure as a service (IaaS). For example, Amazon Elastic Compute Cloud (EC2) has 6,521 public virtual machine images. This creates several challenges in management of image files in a cloud computing environment. In particular, a large amount of duplicate data that...
Communication with smart objects currently only works in isolated, sometimes even proprietary islands. This lack of interoperability limits the value of smart objects connected to the Internet of Things (IoT). We propose to use the Extensible Messaging and Presence Protocol (XMPP) to connect IoT islands. XMPP is inherently federated, secure, globally scalable and designed for collaboration. We use...
With the accelerating library information construction of information construction of electronic books, library has become an important means of strengthening management. The latest Microsoft Visual Studio.NET development platform and SQL Server 2000 database server are used to ensure that the system can meet the demands of market for a long period of time. After adjusting the books management system,...
The ATLAS experiment at the LHC (CERN) comprises a large and geographically distributed community of about three thousand scientists from all over the world. A shift crew of about 10 people running the experiment 24/7 supervises the data taking. Information concerning the experiment operation and behavior has to be reported and shared with the whole community. To provide such functionality, a logbook...
We can usually meet some complicated mathematics operations in scientific research and designing soft, though there are few functions in Visual Basic application. This paper introduces using COM Builder and DDE-two design methods of integration of Visual Basic and engineering calculate software MATLAB by examples. The excellence of the integration is proved by data statistic and FFT. Development foreground...
In recent decades, Geographic Information System (GIS) has developed rapidly and has been integrated into all walks of our life. With the changes of people's needs, only some old GIS software could not meet the needs of the market[1]. To meet the growing needs, the GIS secondary development came into being. A large number of experts and scholars began to study it by using computer technology. Many...
The study of map symbols is one of the basic problems of cartography. Map symbols and map symbol library is also one of the core issues of geographic information systems and mapping software. The varieties of GIS systems and mapping software have unusual map symbol definitions, different depicting ways, and different application purposes and approaches. It is a serious problem to share map symbol...
Virtual computing laboratories are widely implemented in universities, especially to support teaching and research in areas such as engineering, computer science, and information assurance. Most existing labs that support teaching or a combination of teaching and research are internally implemented and managed. Some universities are considering migrating their in-house labs into the cloud using solutions...
At present, the level of library management way in most universities is still a manual operation. For the problem of the traditional manual operation is time-consuming and inconvenience, this paper proposes a library management system is designed and implemented based on the web service. In this system, the three-layer architecture is employed, applying model building language that UML carries on...
Learning registry is a network for sharing metadata and paradata about the learning resources. We created experimentally a website that visualizes these data and provides basic interactions with the learning registry, such as viewing the resources, searching, rating, and posting of specific resources to the network. These experiments serve for testing the offered technologies and for the specification...
This paper reports on the progress of work underway at the Centre for Educational Innovation and Technology at the University of Queensland to construct a new remote laboratories architecture based on contemporary and emerging web standards. The RESTlabs architecture uses the concept of self-describing APIs to provide discoverability of capabilities and the replacement of bespoke code with code generated...
This thesis designs a network teaching and leaning Platform based on .NET framework and web technology. The Platform realizes easy communication and interaction between teachers and students under the network teaching and learning environment. In this environment, teachers and students work in collaboration, which helps to promote students' self-learning abilities and collaborative leaning abilities...
In order to make the test questions library system between data integration to realize the information sharing and interaction, this paper puts forward to service oriented SOA based architecture, enterprise service bus ESB message bus, constructs the test model, and the existing questions of the Web services package, hierarchical design of open test questions library system framework.
With the college effective development of information process, college information service platform had been the effective approach for scientific research of staff and students. This paper proposed the construction planning of college information service platform based on the demand-driven information resource, which based on analyses on the employment situation of college graduates; and discussed...
NTT is implementing NGN based on IMS standards. This paper overviews an IMS/NGN test bed in NTT laboratories which is dedicated for the composition and deployment of innovative services over future NGN by using its rich application and service support functions. Two issues experienced during construction and how we solved them are explained.
Along with the unceasing expansion of colleges' library network scale, the problems of network security are obviously increased. This thesis describes the advantages of VLAN and its practical significance on library local area network, and analyses the library network application and structure in colleges and universities. Based on the design of the library network in Xinyang Agricultural College,...
In this paper, we present a runtime compilation and tuning framework for parallel programs. We extend our prior work on our auto-tuner, Active Harmony, for tunable parameters that require code generation (for example, different unroll factors). For such parameters, our auto-tuner generates and compiles new code on-the-fly. Effectively, we merge traditional feedback directed optimization and just-in-time...
This article makes detailed analysis and description on the campus network to achieve a higher overall performance, including needs analysis, the goal, the network technology, the method of planning and design, network technology and network design requirements, the overall design scheme, the network equipment selection, device configuration, network planning, and service systems to the campus network...
