As databases can overlap each other, data matching that aims to identify data records or elements describing the same object is one of the fundamental problems in physical integration of databases. Matching results can be applied to induce more accurate and complete object descriptions, remove data redundancy, check data consistency and generate cross-links. In this paper, we present a multilevel...
When applied semantic integration technology to databases, common method is to rewrite semantic query into SQL statements, while only RDFs vocabularies are supported at most. Semantics having been realized is weak. A more perfect algorithm inherited from the idea of rewriting semantic query is proposed, a sub set of OWL is supported, and semantics having been supported is more deep than ever. Ontology...
According to the characteristics and requests of data analysis of traffic information, data mining techniques are put forward to apply to the management and decision-making of traffic information. Based on this foundation, an integrated model of the traffic information intelligent analysis and decision support is further given. This model has data mining techniques and data warehouse at its core,...
We have investigated the POD-assisted projective integration method for solving the Navier-Stokes equation based on the equation-free framework. The demonstration of the method is done on the flow past a two-dimensional airfoil(NACA0012) at the Reynolds number of 800. The efficiency of the method in reducing the computational time while maintaining satisfactory accuracy in both transient and periodic...
It is widely considered that standardization is an important means for information processing, exchanging, managing and clearing up technical bulwark more effectively. The paper studied the theoretics and methods about the SaaS platform. After analyzing the issues of standardization and existing standards for sustainable development information sharing (SDIS) such as XML, RosettaNet and so on. The...
It is important to design an integrated information resource management platform in supply chain system. In this paper, the practical problems to integrate supply chain information are firstly put forward. Then Design-Chain Operations Reference-model (DCOR model) is introduced, which is a cross-industry tool for design-chain management. Finally, this paper designs the logical model and workflow model...
With the development of society and economy, the rapid urban sprawl in land use is being witnessed of late in urban districts. As a result, many problems in society and environment have appeared in urban districts, such as population expansion, air pollution, etc. Assessment and inventory on urban sprawl is essential for city planning and sustainable development. The objective of this study was to...
Calderon's method was introduced to electrical capacitance tomography with square sensor in this paper. It is a direct algorithm of the image reconstruction, as no matrix inversion or iterative process is needed. It was implemented through numerical integration. Since the Gauss-Legendre quadrature was applied and can be predetermined, the image reconstruction process was fast and resulted in images...
In this paper, we present DSAM, a data stream application manager. DSAM supports the deployment of global queries to distributed and heterogeneous sensor nodes and stream processing systems (SPSs). We provide a graph-based global query language DSAM-AQL. The abstract query language (AQL) is a declarative streamoriented query language that abstracts from topology and distribution of wireless sensor...
In this paper an outline is presented of historical and current developments in the application of recurrent Taylor series to the integration of systems of ordinary differential equations. The idea of an extremely accurate and fast method for numerical solutions of differential equations is presented in the paper. In general Taylor series are not included or not even mentioned in surveys on numerical...
A media-independent access control function is proposed to arbitrate access of two types of traffic running on a terminal with concurrent accessibility to two different networks. Specifically, voice and data traffic, and UMTS and WLAN networks are to be considered. To improve its QoS, voice traffic is given preferential access to the Cellular network, while data is assumed to have preferential access...
It is recognized within data fusion domain that the main challenge in devising gradient order fusion algorithm is to provide a feasible architecture in fusion system, which will comprise concerned entities in diverse subject-specific fusion model, besides, the characteristics, fusion situations and interrelations among system components have been demonstrated the key factors in the decomposition in...
We address multistream sign language recognition and focus on efficient multistream integration schemes. Alternative approaches are investigated and the application of Product-HMMs (PHMM) is proposed. The PHMM is a variant of the general multistream HMM that also allows for partial asynchrony between the streams. Experiments in classification and isolated sign recognition for the Greek sign language...
Web service infrastructures access heterogeneous remote systems to execute Web service requests. The way in which these remote systems are accessed is not standardized and requires to perform complex integration tasks which are often solved by developing adapters. In this paper, we apply a virtualization approach so that Web service infrastructures can rely on existing adapters instead of writing...
The outage probability is a fundamental performance metric, which has been widely investigated in the literature. In this paper, we develop a general method to compute the outage given the moment generating function (MGF). When computing the outage using the MGF, integration along the standard Bromwich contour suffers from a loss of accuracy due to oscillatory nature of the integrand. One can address...
Numerical simulation is the effective method of solving Richardspsila equation for whose highly-nonlinear character. Most methods of the numerical solutions improved the special discrete methods, or designed on the basis of physical conservation. Those methods can be solved when one time initial value is given. Combining the self-memory principle, the retrospective time integration method for Richardspsila...
A method for controlling homogeneous nucleation and reducing degree of flow separation in high-speed transonic wet steam flow is presented. The spontaneous nucleation flow in a turbine cascade was numerically studied. The model was implemented within a full Navier-Stokes viscous flow solution procedure, and the process of condensation was calculated by the quadrature method of moments which show good...
A mashup is a Web application that integrates data, computation and GUI provided by several systems into a unique tool. The concept originated from the understanding that the number of applications available on the Web and the need for combining them to meet user requirements, are growing very rapidly. This demo presents MatchUp, a system that supports rapid, on-demand, intuitive development of mashups,...
Methods of numerical solutions of differential equations have been studied since the end of the last century. A large number of integration formulas have been published especially for solving special systems of differential equations. In general, it was not possible to choose the best method but for a subclass of tasks defined by similar properties the most suitable method could always be found. The...
