This article presents an architecture for storing ontologically annotated medical images in a GRID. We will be able to extract information from the annotations, which are represented ontologically using RDF. We implement GRID services associated with the development of methodologies for ontological annotations of data contained in a Data Grid (specifically on the Storage Elements). We also provide...
The emerging computational grid infrastructure consists of widely distributed heterogeneous resources, which makes mapping of increasingly complex applications a very challenging task. Utility Management Systems (UMS) manage large number of workflows with high resource requirements and thereby optimization of resource utilization has to be adapted. In this work we propose the architecture that implements...
Previous distributed anomaly detection efforts have operated on summary statistics gathered from each node. This has the advantage that the audit trail is limited in size since event sets can be succinctly represented. While this minimizes the bandwidth consumed and helps scale the detection to a large number of nodes, it limits the infrastructure's ability to identify the source of anomalies. We...
The conception of grid-based Books resource sharing is proposed as well as the six-layer sharing platform architecture. The construction of the grid-based books resource sharing platform is discussed. Finally, the management process of grid-based books resource sharing platform is illustrated.
Nowadays, more and more databases are distributed in networks. To produce knowledge with the databases, traditional data mining technology should be developed in model, algorithm, strategy, etc. The popular distributed data mining (DDM) systems are introduced and classified into three classes: DDM systems based on parallel data mining agents, DDM systems based on meta-learning, and DDM systems based...
The emerging computational grid infrastructure consists of heterogeneous resources in widely distributed autonomous domains, which makes job scheduling very challenging. Although there is much work on static scheduling approaches for workflow applications in parallel environments, little work has been done on a real-world Grid environment for industrial systems. Utility Management Systems (UMS) are...
In September 2009, the Indian Remote Sensing OCEANSAT-2 satellite was launched from Sriharikota(India). Moreover, OCEANSAT-2 carries on-board a third payload, called ROSA (Radio Occultation Sounder of the Atmospheric) and developed by the Italian Space Agency, which give very accurate information about the vertical structure of the atmosphere, through the exploitation of the GPS Radio Occultation...
This paper presents a tool called SysFlow Workflow Engine (SWE) that is being developed to execute a domain workflow defined using SysML's Activity Diagram. The paper also describes extensions added to the SysML semantics to make them SWE executable. SWE focuses on grid computing, cyberinfrastructure and related domains; however support for other domains can be easily added. SWE aims to provide a...
The objective of knowledge integration is to promote knowledge collection, sharing and retrieval in distributed and heterogeneous environment. Our workgroup develops a domain-oriented model for knowledge integration in distributed heterogeneous environment such as semantic grid, which promises better access to relevant knowledge by producing a global domain ontology that is used for establishing semantic...
The Web service resource framework (WSRF) announced in January 2004 is a new mechanism to express how web services interact with the stateful resources, and it has achieved the fusion of Web services and grid services. For the grid application development, WSRF.NET is much easier than Globus Toolkit 4 and it is based on Windows. As WSRF.NET doesn't provide an available scheduler, we introduce Condor...
In order to track and manage the computing resource usage and allocate resources scientifically, meteorological computing resource management system is developed based on meteorological computing Grid. We explore to establish an abstract meteorological model and a computing resources management database for describing the meteorological computing resources on an unified form. National meteorological...
In recent years, Grid Computing has become a key technology in resource integration and sharing, thus improving scientific collaboration among different institutions. While some applications need access databases spread across the participants of the grid, OGSA-DAI is middleware that enables database integration and sharing from different vendors.By using replication techniques, this work aims to...
As an active aspect in the practice and development of Educational Technology, Education Resource platform is becoming the new growing point. The paper analyzed the problem emerged in current education resource sharing and network, which show a frame Education Resource Grid for Training and Coaching.
Grid computing provides mechanisms for making large-scale computing environments available to the masses. In recent times, with the advent of Cloud computing, the concepts of Software as a Service (SaaS), where vendors provide key software products as services over the internet that can be accessed by users to perform complex tasks, and Service as Software (SaS), where customizable and repeatable...
Studies on digital library service and grid technology have both recently witnessed significant progress while still remains some open problems on how to integrated grid technology into modern library enterprise. Therefore there is an indisputable value in analyze the construction and operation of digital library service based on grid technology. This paper introduces the interrelated grid technology,...
Deployment and configuration of grid computing applications are exhaustive and error-prone tasks, and represent a weak link of the lifecycle of grid applications. To address the problem, this paper proposes AGRADC, an architecture to instantiate grid applications on demand, which incorporates features from the autonomic computing paradigm. This architecture improves the grid application development...
The paper has presented a resource sharing architecture for Web-Based Education based on Open Grid Services Architecture (OGSA) to integrate educational resources and improve resources utilization. Using technologies of the Grid and Web services, the architecture describes Grid services mechanism and implement scheme framework of Web-Based Education Platform. It used Web Services, AJAX and LMS API...
OGSA-DQP provides distributed query processing functionalities on top of OGSA-DAI, presenting the multiple databases as a single one, but it does not address heterogeneous data semantic integration requirements. This paper show the query reformulation based on rules on top of OGSA-DAI and OGSA-DQP, which can implement heterogeneous data semantic integration, and users can submit queries over a single...
In view of the large number of heterogeneous enterprise applications can not be interoperability, not sharing resources, data can not be linked the status quo. OGSA architecture based on the use of the latest GT4 grid development tools to build a data grid platform to integrate existing applications.
By introducing the role concept of computer supported collaborative work (CSCW) into the grid environment, a novel efficient grid resource collaboration model base on facilitator role (FR) is presented. In this model, FRs, the independence components of gird collaboration system, can produce some cooperation elements (CEs) that dynamically collect and intelligently mine the cooperation willingness...
