Porosity is quite significant for the characterization and prediction of transport properties. To simulate the porosity values, a porosity simulation method using Markov model based on cokriging is proposed to simulate the continuous values of porosity. Although cokriging is an unbiased prediction method with minimum prediction variance, original cokriging cannot solve the problem of instability in...
In order to reflect the actual deformation degree and trend of building structure and foundation pit, it was necessary to carry out the deformation measurement of subway construction and information management of construction monitoring. At the present moment, GIS had been applied in many fields but rare in analysis of deformation monitoring data. In this paper, GIS, with powerful capabilities of...
Public sector organizations have a typical tall pyramid like organizational structure with centralized powers and multi layered channels of vertical and horizontal communication giving rise to longer processes of decision making. There is little emphasis on employee involvement, personnel development and improvement of working conditions, which adversely affects the team performance. This paper has...
In multidimensional data analysis, the facts have different granularities, the membership relation of dimension levels are partially contained, such factors will affect the results' veracity and validity. This paper describes the imprecise information caused by the above factors, espectially analyses the impact on group and aggregate operaters, and gives pessimism, optimism and compromise three different...
Spatial Data Warehouses (SDWs) combine spatial databases (SDBs) and data warehouses (DWs) allowing analysis of historical data. This data can be queried using Spatial On-Line Analytical Processing (SOLAP). SDW and SOLAP systems are emerging areas that raise several research issues. In this paper, we refer to a different problem existing in SDWs that motivated us to propose a framework - a conceptual...
Aiming at the difficulty of the process improvement in the small enterprises, an improved method based on SPP Model of CMMI level 3 was proposed. The method mainly used to tailor the document, review, training, role and resource, and it simplified the complexity and enhanced the feasibility in the small enterprises. Finally, the data analysis in the case showed the availability of the tailoring process.
Diagnosis of diseases is well known problem in the medical field. Past research shows that medical database of disease can be train by using various neural network models. Many medical problems face the problem of curse of dimensionality due to the excessively large number of input attributes. Breast cancer is one such problem. We propose the use of modular neural network for effective diagnosis....
Change management or configuration management is becoming necessity for every facet of software system development. Traceability of objects i.e. artifacts or information units becomes core talent for authentic determination of the parametric information over the explicit instance of time. This paper presents the evolving and useful concept of traceability management wrapped in change management paradigm...
In combination with the specific conditions of water plant, the paper puts forward the opening information monitoring system structure for industrial process based on Web technology. From system development perspective, the key techniques of the system development, including Web application development, NETDDE and Socket data communication, ODBC access, data gather, control tactic and real-time data...
Today information systems have become the key factor of current computer based engineering applications. So database are designed to support data storage, processing, and retrieval activities related to data management, and they are the key to implementing engineering information models. However, the current mainstream databases are mainly used for business applications, some new engineering requirements...
The article focuses on small or medium enterprises(SMEs), and briefly discusses the necessity of electronic marketing (E-marketing) using second-hand data on the Internet analysis and comparison. Specifically, it indicates the viral Internet marketing strategy, and analyzes its advantages and applicability. Moreover, base on the characteristics and status of the SMEs, the author points out specific...
Data processing technology is a key technology in ZIGBEE wireless sensor network system. Based on the current fact that ZIGBEE wireless sensor network is suffering from data excess and information shortage, this paper introduces the complex event processing technology, takes the angle from the nature of information and event processing, and researches on the data analysis method of ZIGBEE wireless...
This paper presents a fault diagnosis method for power transformer. Fault diagnosis plays an importance role in the efforts for transformer diagnosis to shift form “preventive maintenance” to “condition based maintenance” (CBM), and consequently to reduce the maintenance cost. Ever since its birth, numerous techniques have been researched in this field, each method however, has its own advantages...
The guidelines for hospital-acquired infections (HAI) published by the Centers for Disease Control and Prevention (CDC) is most comprehensive and detailed. However, it requires a large amount of resources to implement the guidelines in hospital settings, particularly for data collection and analysis. HAI surveillance is time-consuming and costly, and hence HAI surveillance in many hospitals couldn't...
SOA is a new kind of architecture design for system development. It can solve heterogeneous problem by decomposing software services module and integrating service module. Traditional logistics information system has poor scalability and reusability, it is easy to form information islands. E-business logistics information system based SOA provide an ideal framework for design and implementation of...
Aiming at currently data interaction bottleneck problem in large-scale distributed battle simulation system, a new data interactive method which based on layering-synchronizing-sharing policy was proposed. Different from the traditional entity-centric data exchange thought, it was established at the thought of entity classification and situation layering. The outputs of entities model form a situation...
With the development of network technology, computer network is characterized as an uncontrollable, variable and unpredictable infrastructure, this brings great difficulty of verify, defining, debugging and comparing the new schemes. Network simulation technology is proposed to test, appraise, and verify means available. This paper designs and implements an intelligent analyzing tool for NS2 traces,...
In computation flow visualization, integration based geometric flow visualization is often used to explore the flow field structure. A typical time-varying dataset from a Computational Fluid Dynamics (CFD) simulation can easily require hundreds of gigabytes to even terabytes of storage space, which creates challenges for the consequent data-analysis tasks. This paper presents a new technique for path-lines...
According to mass data accumulated in comprehensive database building in water informatization process of China, this paper takes hydrology as an example, discusses how to build data warehouse system base on comprehensive database and how to design general structure of data warehouse. On this basis, organization of multidimensional data of hydrology is constructed in order to service the comprehensive...
More and more spatial data are used with the application and development of modern science and technique; therefore, obtaining the spatial knowledge becomes more and more important and meaningful. The tremendous amounts of spatial and non-spatial data have been stored in large spatial database. These are far beyond the human ability to interpret and analysis of them, which is urgently in need of spatial...
