The rapid development of cloud computing service allows scientific research data to be easily moved into cloud. Users pay for computational and storing resources to deal with their data in the cloud therefore how to manage those resources has become an urgent issue to be solved. Large application data need to be handled every day, thus a good storage strategy can save monetary cost as well as improve...
Spatiotemporal information and application have received considerable attention. Spatiotemporal information is often imprecise or uncertain; therefore, the establishment of a reasonable and effective fuzzy spatiotemporal data model is vital. The traditional tool-based modeling method cannot meet the needs of fuzzy spatiotemporal data modeling. XML has become the standard of Web data representation...
With the help of MapReduce powerful parallel computing ability and good extensibility, we try to solve the bottleneck problem of traditional BP neural network in dealing with the big data for the training sets in this paper. Through the experimental data for the farmland fertilizer effect, we propose that fertilizer rate is taken as input for the neural network, and ultimately yield is taken as the...
It is important for the management of seeds tracing which includes the collection and calculation of seeds sale. In the paper, firstly, we designed and implemented the seeds Hadoop-based trace data processing model, through the processing of the crawl data of seed, such as ETL process, parallel computing, distributed storage. Secondly, we studied the Consistent Hash Algorithm to optimize the database...
By MM5 wind model and SWAN wave model, 41 strong typhoon wave process between 1988 to 2008 in XingHua bay are calculate, the result agree well with the measured typhoon and wave data. Based on numerical simulation result, the different returns period wave parameter at-40m depth water are obtained by P-III frequency curve analysis, the engineering design wave elements are obtained by SWAN wave model...
Information in real world application is often vague or ambiguous. Currently, less research has been done in modeling fuzziness in conceptual data model and design of fuzzy databases. In this paper, based on fuzzy set and possibility theory, the fuzzy IFO model and the corresponding graphical representations are presented. In particular, we provide the approach to mapping a fuzzy IFO model to a fuzzy...
Though the influences of explicit knowledge spillover on economic growth in China have been widely discussed in previous studies, the effects of tacit knowledge spillover and the relationship between tacit and explicit knowledge spillover have been less systematically investigated. This paper assesses how and to what extent tacit knowledge spillover contributes to regional economic growth in China...
From the current research review and defects of the present leakage prediction model analysis, a multivariate grey GM (0, N) (Multi-factor Grey Model) considering the water supply pressure, water supply volume and frequency of leakage was proposed, finally it was used to predict the leakage of water pipe network, the results showed that the precision of grey GM (0, N) model was greatly improved in...
Virtual human motion capture data has been widely applied in virtual reality, computer animation, etc. It is important to segment the motion data into small clips automatically in order to reuse these data. In this paper, a new method of motion capture data segmentation is proposed based on kernel dynamic texture. First we model the motion capture data using kernel dynamic texture, and then on the...
As the next generation of the Web language, XML is straightforwardly usable, which has been the de-facto standard of information representation and exchange over the Web. XML employs a tree-structured data model, and XML queries specify patterns of selection predicates on multiple elements related by a tree structure. Due to increase in web-based applications, searching for all occurrences of a twig...
With the rapid development of Internet technology, web information system has achieved great development, and XML, as the new carrier and standard of information exchanging and calculating on the internet, has been widely used as well. While providing a uniform syntax and semi-structured data model, XML does not express semantics but only structure. This paper combines the web data integration problem...
The paper presents a novel Multi-Resolution Model (MRM) of Logistics Location based on the theory of MultiResolution Modeling. Using MRM simulation thoughts, it points out the necessity of MRM of Logistics Location by analyzing the key technology of MRM. The paper develops a Decision Support System (DSS) with Model-View-Controller (MVC) pattern and spatial database based on Cost-Revenue model (C-R)...
Two-level hybrid fusion model of a multi-sensor data system, which fits the system of intelligent control of greenhouse, is presented. At first, the local fusion model is given to fuse the information from different sensors which use to collect parameters of greenhouse environment; then the information is fused in improved Yager theory. Local and global fusion results will be stored in knowledge base...
In order to model complex objects with imprecision and uncertainty, fuzzy object-oriented databases have been proposed. In this paper, some algebraic operations are investigated based on a kind of fuzzy object-oriented database model. We also discuss fuzzy query processing of the fuzzy object-oriented databases.
Information in real world application is often vague or ambiguous. Currently, less research has been done in modeling fuzziness in conceptual data model and design of fuzzy databases. In this paper, based on fuzzy set and possibility distribution theory, the fuzzy UML model and the corresponding graphical representations are presented. In particular, we provide the approach to mapping a fuzzy UML...
In order to solve the problem of non-linear in mixed gas infrared spectra analysis, the data fusion method based on support vector machine is used. Data fusion is a new information processing method, and it may use superfluous and complementary information to improve the performance of output, and the data fusion model is established. The non-linear processing function of support vector machine is...
In this paper, based on possibility distribution and the semantic measure of fuzzy data, we investigate subclass-superclass relationships in the fuzzy object-oriented databases. We identify fuzzy class and develop soft computing methods in the paper to quantitatively determine the fuzzy subclass-superclass hierarchies. The strategies to resolve the conflicts in multiple inheritance of class are also...
In order to deal with complex as well as uncertain information, in this paper, we introduce fuzzy data into nested relational database model, where data fuzziness appears in forms of possibility distribution and resemblance relations in the universe of discourse. We present the structure of fuzzy nested relational model and define the algebra for manipulating fuzzy and complex data.
Intelligent Agent is being applied to User Interface Domain increasingly. This paper describes the features of user interface model based on the Agent, analyzes the principle and function of the model, view and controller in the model-view-controller( MVC) framework. The object-oriented model using MVC can improve design efficiency. In a broad sense, a practical system is given as an example to implement...
The metadata plays an essential role in data warehouse for banks. Based on system developing experience, the paper discusses the categories and functions of metadata, and elaborates how to use metadata to manage system. At last the paper presents the architecture of a Metadata Management System based on data warehouse for banks, and illustrated and analyzed its structure. Application results show...
