Palmprint recognition has received in the last 20 years a great deal of the research community's attention. In this paper a new palmprint matching approach based on corner feature point extraction is proposed. A 72-element fixed-length descriptor is used to capture distinctive information of each feature point neighborhood and to build a measure of similarity whilst their coordinates provide a measure...
It is known that the features of the radio station vary with the signal to noise ratio (SNR) in a certain range which leads to the uncertainty of the radio station identification system. In this paper, we study the interval evidence recognizer by extending the individual features of the obtained radio from single value to interval and constructing the radio station feature database. Firstly, the range...
An ECG process based on Einthoven principle was developed for this study. A circuit and DAQ card were incorporated in a human machine interface using LabVIEW to detect the PQRSTpoints in ECG and display the processed ECG signals of the test subjects. The ECG data saved were plotted into dynamical map of chaotic dynamic error using a master-slave chaos system. Chaos eye was selected as the feature...
Objective: By the systematic evaluation of previous literature, this study was to look for the evidence of evidence-based medicine to objectively evaluate the clinical efficacy, Security. Methods: From 1993 January to 2012 December nearly twenty years of EA in the treatment of functional constipation of domestic and foreign clinical randomized controlled studys, develop quality evaluation and meta...
with the spread of a large number of web application, more and more software requirements are proposed. Especially in management information system, it is necessary to maintain the scalability of the database and the flexibility of the software architecture. To meet the development of the software, a lot of novel technologies are presented. The framework based on Struts, Spring and Hibernate is one...
Insulators will be in operation process when insulation performance drop coincided with a surface discharge, the operation state detection by UV camera can found fault insulator effectively, which be a timely maintenance and low breakdown. Combined with DCUHV engineering technology national engineering laboratory (Kunming) site demand design, we develop a set of ultraviolet data management system...
Based on object deputy database, newly proposed web data management system (WDMS) provides user with personal data spaces to flexibly manage their various web data. Limited to database capacity, WDMS should gather data that user need from Web according to user demand implied in their personal data spaces. However, user demand that expressed in SQL sentences in data spaces can't be comprehended and...
In this paper, we propose a novel evaluation method for defect prediction in object-oriented software systems. For each metric to evaluate, we start by applying it to the dependency graph extracted from the target software system, and obtain a list of classes ordered by their predicted degree of defect under that metric. By utilizing the actual defect data mined from the subversion database, we evaluate...
Based upon the software reliability and reliability design of information system, this paper puts forward various measures of software structure design, software error-avoided design of simplified design, reuse design and interface design, software error-tolerated design of redundancy design, robust design and recovery design, software error checking and correcting design. Thenceforth a primary prospect...
In this paper, we present a revised method to compute the similarity of traditional string edit distance. In order to compute the edit distance, a new algorithm is introduced. This algorithm is shown to work in O (m*n*(n)) time and O(n*m) memory space for strings of lengths m and n. Content-based video retrieval is a challenging field, and most research focus on the low level features such as color...
Deep Web information integration has become more and more important due to its rich and high quality data. How to select the most appropriate web database relevant to user's requirement is challenging. However, the existing researches only focus on the data source selection method and ignore the expression of user's query requirement. This paper presents a user query requirements modeling language,...
The protection of ethnic minorities' nonmaterial heritages is becoming a new focus of culture protection in China. For trying to explore a new way of protecting the ethnic minorities' nonmaterial heritages with the help of information technology, the research in this paper describes the designing and fulfilling route and methods of web-based multimedia resources system of ethnic nationalities' nonmaterial...
Gait is one of the biometric technologies which can be identified as an individual by his/her walking style. This paper proposes an effective gait recognition method based on mean gait energy image(MGEI) which utilizes kernel principal component analysis(KPCA). KPCA is capable of capturing part of the high-order statistics which are particularly important for MGEI structure. MGEI is calculated from...
With the rapid growing of data on Web, we are facing three serious problems. Firstly, there are a huge number of data resources which are heterogeneous and dynamic.Secondly, most of data on Web are unstructured. Thirdly, there are various kinds of Web users who have different interests and requirements. In this paper, we proposed a new system architecture for unstructured data management on Web to...
Naive Bayes Classifiers have been known with the advantages of high efficiency and good classification accuracy and they have been widely used in many domains. However, the classifiers need complete data. And the phenomenon of missing data widely exists in practice. Facing this instance, learning naive Bayes classifier and classification method with missing data are built in this paper. Compared with...
Authorization takes a significant role in grid security, and the function of the agent is more and more obvious in the grid environment. However, some popular grid toolkits (e.g., Globus) do not support agent technology. In order to enhance the real-time validity of the authorization process, lighten the userspsila burden, reduce the cost of management and apply intelligent authorization, this paper...
Since many differences may arise in cognition, abstraction and representation during multi-scale road network compositive modeling, this paper proposes an hierarchical ontology-based multi-scale entity-Relation modeling strategy, it considers ontology integration from the bottom level-general ontology in geographical science, to task ontology for road network features cognition, definition,abstraction,...
Multi-scale representations for geographical entities is one of research focuses in the field of multi-scale spatial database, Compared with the traditional GIS model, the essential modeling mechanism and strategies for building multi-scale data model are explored. Taken the road feature as an example, a detailed description of multi-representation model elements in the multi-scale model are provided,...
Inter-connectivity maintenance among multi-representations exists as a foundational task in building multi-scale data model, however, the existing methods are still not satisfactory in practice. In this context, the paper considers that the inter-connectivity among multiple representations can be only achieved if the multi-scale model is capable of explicitly inter-relating them and dealing with their...
In this paper, an intelligent process and product quality assurance (PPQA) Web services for capability maturity model integration (CMMI) assessment is proposed. The intelligent Web services are implemented by following the specific goals of PPQA process area of CMMI and contain an evaluating processes and work products service (EPWPS), a providing objective insight service (POIS), an ontological reasoning...
