Nowadays, multi-core processor architectures have been widely adopted in main domains e.g., embedded, general-purpose, real-time systems, etc. Diverse thermal managements have been proposed to manage the temperature under various constraints. This has made the selection of the right thermal management policy difficult. Designers need to validate any resource distribution decision in design phase on...
The percentage of gas-fired generating units in China is increasing rapidly in recent years. Due to the uncertainty in natural gas supply and the shared usage by other industries and residents, the available natural gas supply cannot be predicted day-ahead precisely. To represent the stochastic nature of natural gas supply of power plants, we propose a two-stage stochastic programming model for the...
Identifying prospective customers is an important aspect of marketing research. In this paper, we provide support for a new type of query, the Reverse Top-k Geo-Social Keyword (RkGSK) query. This query takes into account spatial, textual, and social information, and finds prospective customers for geotagged objects. As an example, a restaurant manager might apply the query to find prospective customers...
The goal in similarity search is to find objects similar to a specified query object given a certain similarity criterion. Although useful in many areas, such as multimedia retrieval, pattern recognition, and computational biology, to name but a few, similarity search is not yet supported well by commercial DBMS. This may be due to the complex data types involved and the needs for flexible similarity...
Various big data management systems have emerged to handle different types of applications, which cast very different demands on storage, indexing and retrieval of large amount of data on distributed file system. Such diversity on demands has raised huge challenges to the design of new generation of data access service for big data. In this paper, we present PABIRS, a unified data access middleware...
The corporate network is often used for sharing information among the participating companies and facilitating collaboration in a certain industry sector where companies share a common interest. It can effectively help the companies to reduce their operational costs and increase the revenues. However, the inter-company data sharing and processing poses unique challenges to such a data management system...
High-speed video provides a way to record physiological vibrational patterns of the vocal folds. Due to the large amount of data it produces, many methods have been proposed to reduce raw images to the underlying vibrational patterns. Previous methods either focus on a certain location on the vocal folds, or a certain frequency of vibrational activity. In this paper, we propose the “glottaltopograph”...
How to take reasonable and scientific decision-making method to select the better limited bidding schemes is a main question in the project bidding evaluation. This article introduces the ELECTRE-I method, on the basis of building indicator matrix, determine higher-level relations between different bid schemes, through accordance and disaccord examine, and seek for the non-inferior scheme subset unceasingly,...
The development of Economic is inseparable from the support of financial.Rural credit cooperatives are the mainstay of supporting the development of county economy??Cso measuring the development level of rural credit cooperatives has the extremely vital significance. This paper has selected 17 indexes by using factor analysis to measure the management strength of rural credit cooperatives,then concludes...
Spatial autocorrelation is an important spatial statistical method in Geographic Information Systems, which can reveal spatial structures and patterns of regional variables. With this method, this article calculates the population density's spatial correlation model for county-level units in Jiangsu province of China in 2001, 2002, 2003 and 2004, explores and demonstrates every county-level's global...
By employing Moran's I and Gini coefficient as measures of spatial concentration, we explore the spatial patterns of interprovincial migration sharing the same origin or destination in China, 1995–2000. The values of Moran's I and Gini for out-migration streams of each province as an origin and in-migration streams of each province as a destination are estimated accordingly. Through comparing these...
The ascertainment of the index weight is the core process in establishing the evaluation index system. The equipment maintenance support effectiveness evaluation indexes are described. The essay maintains to make use of an improved community judgment AHP method to ascertain the weight of each layer index and quantized them. The paper adopts a threshold method on the standardize procession. It solved...
As an important indicator to measure a city's regional economic and social value, accessibility is more and more used in tourism and urban planning, transport design, public facilities and some other issues. Traditional accessibility study is mostly focus on a limited number of points. In this paper, GIS technology is used to establish an innovative areal model of the whole city's accessibility, in...
When trying to discover knowledge on a collection of data, one of the first arising tasks is to identify groups of similar objects, that is, to carry out cluster analysis for obtaining data partitions. Thus, a decision must be taken for choosing the clustering result that produces the best data partition for a given data collection. In order to support such a decision, indexes for measuring the quality...
Thanks to standard specifications for Web services, more and more data is represented and exchanged in XML. Efficiently finding all occurrences of a twig pattern is a core operation of XML query processing. Recently, a large number of holistic twig join algorithms have been proposed, however ordered XML twig join has been ignored in most of them. In this paper we design a novel algorithm called OTJFast...
Efficiently finding all occurrences of a twig pattern is a core operation of XML query processing. In this paper, we first propose a generic twig join algorithm TJFGeneric which only scans the leaf query nodes using a cursor interface to return elements. And then we present TJFGeneric+ algorithm incorporating two optimization rules into TJFGeneric to explore potential benefit of disk read and CPU...
