Data Exchange in Grid Workflow

In existing web services-based workflow, data exchanging across the web services is centralized, the workflow engine intermediates at each step of the application sequence. However, many grid applications, especially data intensive scientific applications, require exchanging large amount of data across the grid services. Having a central workflow engine relay the data between the services would resu＇lts in a bottleneck in these cases. This paper proposes a data exchange model for individual grid workflow and multiworkflows composition respectively. The model enables direct communication for large amounts of data between two grid services. To enable data to exchange among multiple workflows, the bridge data service is used.

Flexible substructure online hybrid test system using conventional testing devices

This paper presents a substructure online hybrid test system that is extensible for geographically distributed tests. This system consists of a set of devices conventionally used for cyclic tests to load the tested substructures onto the target displacement or the target force. Due to their robustness and portability, individual sets of conventional loading devices can be transported and reconfigured to realize physical loading in geographically remote laboratories. Another appealing feature is the flexible displacement-force mixed control that is particularly suitable for specimens having large disparities in stiffness during various performance stages. To conduct a substructure online hybrid test, an extensible framework is developed, which is equipped with a generalized interface to encapsulate each substructure. Multiple tested substructures and analyzed substructures using various structural program codes can be accommodated within the single framework, simply interfaced with the boundary displacements and forces. A coordinator program is developed to keep the boundaries among all substructures compatible and equilibrated. An Interuet-based data exchange scheme is also devised to transfer data among computers equipped with different software environments. A series of online hybrid tests are introduced, and the portability, flexibility, and extensibility of the online hybrid test system are demonstrated.

XML-based Data Processing in Network Supported Collaborative Design

In the course of network supported collaborative design, the data processing plays a very vital role. Much effort has been spent in this area, and many kinds of approaches have been proposed. Based on the correlative materials, this paper presents extensible markup language （XML） based strategy for several important problems of data processing in network supported collaborative design, such as the representation of standard for the exchange of product model data （STEP） with XML in the product information expression and the management of XML documents using relational database. The paper gives a detailed exposition on how to clarify the mapping between XML structure and the relationship database structure and how XML-QL queries can be translated into structured query language （SQL） queries. Finally, the structure of data processing system based on XML is presented.

Research on Application Technology Oriented Rapid Response Manufacturing in the Distributed Network Environment

A new chance of developing traditional manufacturing industry comes forth with the development of network technology. Application technology oriented rapid response manufacturing in the distributed network environments, that is, how to take advantage of the Intranet and Internet, combine the numerous manufacturing resources spread around the region, the country and even the globe is the key to the agile design, manufacturing and the buildup of comprehensively competitive power, at the same time, is also an important research direction in the field of advanced manufacturing technology. Rapid response manufacturing in the distributed network environment is a newly manufactory pattern that can be used to implement the conception of agile design and manufacturing, but there are some new problems coming with it, which will directly influence the enterprise’s ability of rapid response in the distributed network manufacturing pattern and lead to the failure of the league and the lost of the given orders. In this paper, we establish some approaches to solve these problems in product development process. The paper then presents the research on key application technologies and solutions includes: network safety strategy which guarantees data transferring among the leaguer members, production data management based on Web/DOT (Distributed Object Technology) and XML criteria which guarantees data exchange in structure-variance characteristic environments, the network platform which provides the conversion service of different types of CAD files each other. All of these solutions are aim for technology problems existing in the distributed network environments and among the league members. Finally, the paper takes one project, that is, the establishment of the online application service system for Shanghai Advance Manufacturing Technology Research Center as a good instance.

Tractable XML data exchange via relations

We consider data exchange for XML documents： given source and target schemas, a mapping between them, and a document conforming to the source schema, construct a target document and answer target queries in a way that is consistent with the source information. The problem has pri- marily been studied in the relational context, in which data- exchange systems have also been built. Since many XML documents are stored in relations, it is natural to consider using a relational system for XML data exchange. However, there is a complexity mismatch between query answering in relational and in XML data exchange. This indicates that to make the use of relational systems pos- sible, restrictions have to be imposed on XML schemas and mappings, as well as on XML shredding schemes. We isolate a set of five requirements that must be ful- filled in order to have a faithful representation of the XML data-exchange problem by a relational translation. We then demonstrate that these requirements naturally suggest the in- lining technique for data-exchange tasks. Our key contribu- tion is to provide shredding algorithms for schemas, docu- ments, mappings and queries, and demonstrate that they en- able us to correctly perform XML data-exchange tasks using a relational system.

A Review on TSO-DSO Data Exchange,CIM Extensions and Interoperability Aspects

The exchange of information between transmission system operators(TSOs)and distribution system operators(DSOs)is a common practice.However,the evolution of the regulatory frameworks in Europe has increased the need for enhancing TSO-DSO data exchange and interoperability.This paper provides an overview of the TSO-DSO data exchanges and demonstrates the best practices using International Electrotechnical Commission(IEC)common information model(CIM),including the implementation of IEC common grid model exchange standard(CGMES),and discussion of the corresponding advantages,disadvantages,and challenges.Furthermore,this paper evaluates and reports the activities already carried out within European projects,with particular focus on TSO-DSO interoperability.Finally,this paper concludes the need for TSOs and DSOs to rely on standard-based solutions when performing TSO-DSO data exchange,which enables the efficient operation and development of the future power systems.

Horn of plenty:Value of the international registry for pediatric chronic myeloid leukemia

Chronic myeloid leukemia(CML)in minors is a rare disease which can be effectively treated by tyrosine kinase inhibitors(TKIs)since the year 2000.A majority of pediatricians will encounter one or two CML patients in the course of their careers and will typically have to rely on written information along with their own intuition to provide care.Knowledge of response to TKIs and of agespecific side effects has an impact on the design of pediatric CML trials in many ways aiming to contribute toward greater predictability of clinical improvements.Information from a registry on a rare disease like CML offers the enormous benefit of enabling treating physicians to interact and share their collective experience.The International Registry on Pediatric CML(IR-PCML)was founded at Poitiers/France almost 10 years ago.Since then,the number of collaboration centers and in parallel of registered patients continuously increased(>550 patients as of December 2019).Ideally,from a given treatment center in a country data are transferred to a national coordinator who interacts with the IR-PCML.In the sense of quality assurance,the registry can offer dissemination of knowledge on state-of-the-art diagnostics(including reference appraisal),optimal treatment approaches,and follow-up procedures within a network that is exerting its strength via participation.With continuous growth during the recent years,very rare subgroups of patients could be identified(e.g.,CML diagnosed at age<3 years,children presenting with specific problems at diagnosis or during course of treatment)which had not been described before.Publications coming from the IR-PCML disseminated this useful information derived from patients who robustly participate and share information about their disease,among themselves and with their caregivers and clinicians.Patient input driving the collection of data on this rare leukemia is the basis for the considerable success of bringing new therapeutics into clinical use.

An efficient parallel algorithm for ocean circulation numerical model based on irregular rectangle decomposition scheme

A parallel algorithm of circulation numerical model based on message passing interface（MPI） is developed using serialization and an irregular rectangle decomposition scheme. Neighboring point exchange strategy（NPES） is adopted to further enhance the computational efficiency. Two experiments are conducted on HP C7000 Blade System, the numerical results show that the parallel version with NPES（PVN） produces higher efficiency than the original parallel version（PV）. The PVN achieves parallel efficiency in excess of 0.9 in the second experiment when the number of processors increases to 100, while the efficiency of PV decreases to 0.39 rapidly. The PVN of ocean circulation model is used in a fine-resolution regional simulation, which produces better results. The capability of universal implementation of this algorithm makes it applicable in many other ocean models potentially.

Study on Distributed Knowledge Information System for Product Design

To overcome the limitations of commercial CAD and handbook form of knowledge expression, the Distributed Knowledge Information System (DKIS) for product design is proposed. The structure of DKIS and the key issues in its implementation are introduced; the method of knowledge store and transfer of DKIS is discussed. The mechanism of knowledge representation, acquisition and utilization, based on Internet network, is achieved. Based on the concept of function driven, integrated Artificial Neural Networks and Active Server Pages techniques, transplanting the trained ANN into DKIS system, a new method for retrieving knowledge in DKIS over Internet is achieved. Finally, a prototype of DKIS is developed to demonstrate the feasibility of the structure and constructional method of DKIS. The work pro-vides a scheme for speed knowledge acquisition and shortens the cycle of product development.

STEP-based Feature Recognition System for B-spline Surface Features

The geometrical and topological information of 3D computer aided design （CAD） models should be represented as a neut- ral format file to exchange the data between different CAD systems. Exchange of 3D CAD model data implies that the companies must exchange complete information about their products, all the way from design, manufacturing to inspection and shipping. This informa- tion should be available to each relevant partner over the entire life cycle of the product. This led to the development of an international standard organization （ISO） neutral format file named as standard for the exchange of product model data （STEP）. It has been ob- served from the literature, the feature recognition systems developed were identified as planar, cylindrical, conical and to some extent spherical and toroidal surfaces. The advanced surface features such as B-spline and its subtypes are not identified. Therefore, in this work, a STEP-based feature recognition system is developed to recognize t--spline surface features and its sub-types from the 3D CAD model represented in AP203 neutral file format. The developed feature recognition system is implemented in Java programming language and the product model data represented in STEP AP203 format is interpreted through Java standard data access interface （JSDAI）. The developed system could recognize B-spline surface features such as B-Spline surface with knots, quasi uniform surface, uniform surface, rational surface and Bezier surface. The application of extracted B-spline surface features information is discussed with reference to the toolpath generation for STEP-NC （STEP AP238）.

StarFL - a modularised metadata language for sensor descriptions

An ever-increasing number of sensor resources are being exposed via the World Wide Web to become part of the Digital Earth.Discovery,selection and use of these sensors and their observations require a robust sensor information model,but the consistent description of sensor metadata is a complex and difficult task.Currently,the only available robust model is SensorML,which is intentionally designed in a very generic way.Due to this genericness,interoperability can hardly be achieved without the definition of application profiles that further constrain the use and expressiveness of the root language.So far,such SensorML profiles have only been developed up to a limited extent.This work describes a new approach for defining sensor metadata,the Starfish Fungus Language(StarFL)model.This language follows a more restrictive approach and incorporates concepts from the recently published Semantic Sensor Network Ontology to overcome the key issues users are experiencing with SensorML.StarFL defines a restricted vocabulary and model for sensor metadata to achieve a high level of interoperability and a straightforward reusability of sensor descriptions.

A RESTful proxy and data model for linked sensor data

The vision of a Digital Earth calls for more dynamic information systems,new sources of information,and stronger capabilities for their integration.Sensor networks have been identified as a major information source for the Digital Earth,while Semantic Web technologies have been proposed to facilitate integration.So far,sensor data are stored and published using the Observations&Measurements standard of the Open Geospatial Consortium(OGC)as data model.With the advent of Volunteered Geographic Information and the Semantic Sensor Web,work on an ontological model gained importance within Sensor Web Enablement(SWE).In contrast to data models,an ontological approach abstracts from implementation details by focusing on modeling the physical world from the perspective of a particular domain.Ontologies restrict the interpretation of vocabularies toward their intended meaning.The ongoing paradigm shift to Linked Sensor Data complements this attempt.Two questions have to be addressed:(1)how to refer to changing and frequently updated data sets using Uniform Resource Identifiers,and(2)how to establish meaningful links between those data sets,that is,observations,sensors,features of interest,and observed properties?In this paper,we present a Linked Data model and a RESTful proxy for OGC’s Sensor Observation Service to improve integration and inter-linkage of observation data for the Digital Earth.

STUDY ON AIR-SEA HEAT EXCHANGE MECHANISM IN EL NINO AND LA NINA EVENTS

2°×2° mean monthly COADS grid data in 1974 and 1987 of E1 Nino and La Nina years are used to compute the sensible and latent heat fluxes,the net longwave radiation,the incident solar radiation and heat budget on the tropical Pacific surface(30°S—30°N).The difference of the heat budget between El Nino and La Nina mainly occurred on the equatorial ocean surface,especially the water area west of Ecuador and Peru.During El Nino,the sensible and latent heat exchange increased,the net longwave radiation and incident solar radiation decreased and the net gain(loss) of heat reduced(increased) on the ocean surface.During La Nina,the circumstances were opposite.Finally an ideal model of air-sea heat exchange mechanism for the El Nino-La Nina cycle is summarized.

Geological applications using geospatial standards-an example from OneGeology-Europe and GeoSciML

The Geoscience Markup Language(GeoSciML)has been developed to enable the interchange of geoscience information,principally that portrayed on geological maps as well as boreholes.A GeoSciML testbed was developed both to test the implementation of the data model and its application in web services.The OneGeology-Europe project aims to use the GeoSciML data model,and build on the experience of the GeoSciML testbed,in implementing a geoportal for a harmonised geological map of Europe at 1:1 million scale.This involves the integration of web services from 20 participating organisations.An important objective of OneGeology-Europe is to contribute to Infrastructure for Spatial Information in the European Community(INSPIRE),both through the development of a geological data specification and the use of the INSPIRE technical architecture.GeoSciML and the OneGeology-Europe project are also steps towards incorporating geoscience data into a Digital Earth.Both the development of GeoSciML and the implementation of web services for GeoSciML and OneGeology-Europe,have followed a standards-based metho-dology.The technical architecture comprises a geoportal providing access to a Catalogue Service for the Web for metadata describing both the data and services available.OneGeology-Europe will provide bothWeb Map Services view andWeb Feature Services download services,which aim to be compliant with the INSPIRE implementing rules.

The application of open standards to enhance the interoperability of geoscience information

We can adequately study broad global issues and policies only by taking geosciences into account.Our research and decision-making must share and make effective use of interdisciplinary data sources,models,and processes.Noninteroperability impedes sharing of data and computing resources.Standards from the Open Geospatial Consortium(OGC)and other organizations are the basis for successfully deploying a seamless,distributed information infrastructure for the geosciences.Several specifications now adopted by the OGC consensus process are the result of OGC interoperability initiatives.The OGC standards,deployment architectures,and interoperability initiatives are described showing how the OGC standards baseline has been developed and applies to the geosciences.

Novel Mesh Technique and Its Application in the Wind Field Simulation for Flexible Spatial Structure

In this paper,novel mesh techniques are proposed for wind field simulation of flexible spatial structure.For mesh generation,an interpolation strategy is presented to obtain a mesh system with variable density.Two spatial structure examples are used to examine the efficiency and applicability of this technique.Then based on the structured mesh system generated by the technique,the mesh nodal coordinates are updated to adapt the moving boundary conditions by means of the mapping interpolation functions and some examples are given to verify the effectiveness.Furthermore,the constrained counterforce distribution technique and projection interpolation strategy are developed to implement the data exchange on the interaction surface of wind and structure.Finally,the computational accuracy is numerically validated.

Mediating among GeoSciML resources

Integration of data across multiple independently developed data sources can be challenging due to a variety of heterogeneities that exist across such systems.Data mediation technologies provide approaches for overcoming these heterogeneities.Standards such as Geoscience Markup Language can address some of the heterogeneity issues by providing schema standards which sources can adhere to.This article addresses the issue of semantic heterogeneity across information resources by using domain ontologies and registering schema elements and data values to such ontologies.Registering data to ontologies provides a powerful search and data integration capability across disparate geoscience information resources.
