Accurate classification and recognition of pulmonary nodules is an important and key process of Computer-Aided Diagnosis (CAD) system in lung cancer diagnose. Although it has become an increasingly popular research topic, it remains a lot of scientific and technical challenges. Not only do we lack the accurate and effective algorithm of recognition and classification, but also we have difficulties...
Constructing complex queries in SQL sometimes necessitates the use of language constructs and the invocation of internal functions which inexperienced developers find hard to comprehend or which are unknown to them. In the worst case, bad usage of these constructs might lead to errors, to ineffective queries, or hamper developers in their tasks.
A graph is used to represent data in which the relationships between the objects in the data are at least as important as the objects themselves. Over the last two decades nearly a hundred file formats have been proposed or used to provide portable access to such data. This paper seeks to review these formats, and provide some insight to both reduce the ongoing creation of unnecessary formats, and...
Software reuse is a solution to reduce the costs of estimation, design, development, and testing. Reuse of source codes can release the coders from the time-killing botheration of doing the same coding again and again for same kind of software projects. If the proposed distribution format (Application→ Module→Class→Function→Sub-function) is followed while storing source codes, then it is easier to...
Framework-based1 applications are quite popularly used in current commercial applications. Framework-based applications are often controlled by XML configuration files. However, most of these frameworks are complex or not well documented, which poses a great challenge for programmers to correctly utilize them. To overcome these difficulties, we propose a new method to recommend XML configuration snippets...
The old manuscripts kept in libraries are a part of the richest cultural heritage and legacy of civilizations. Digitalization is a solution for the preservation of this cultural and historical heritage, which is very difficult to handle for users. The automatic or manual transcription of old Arabic manuscripts is an inevitable stage for the indexing and the diffusion of the contents of these manuscripts,...
This paper presents an overview of the design and implementation of a framework for automated test code generation of SQL stored procedures in a .NET managed code environment, using SQL, XML and the C# programming language. The primary knowledge and coding skills required for developing and using the framework are SQL, XML, and C#. The framework is most useful in a software development scenario where...
While Telemedicine technology greatly increases the quality of medical care with less health care costs, it also raises critical challenges for data security and privacy in the course of data entry, data review, patient education, video conference, and electronic monitoring. To meet these various needs, a number of different of security strategies can be utilized. In this study, we aim to secure user-related...
In this paper, we consider two kinds of unordered tree matchings for evaluating tree pattern queries in XML databases. For the first kind of unordered tree matching, we propose a new algorithm, which runs in O(|D||Q|) time, where Q is a tree pattern and D is a largest data stream associated with a node of Q. It can also be adapted to an indexing environment with XB-trees being used to speed up disk...
The globalization trend has been affecting Central and Eastern European countries since the 1990s. A number of countries, each with its distinct language and culture, have been established after the fall of the Soviet Union and Yugoslavia. To successfully target this market a presentation form is needed that takes into account these unique circumstances. Today, the World Wide Web provides a basis...
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...
An algorithm, TBCClustering, is presented in the paper for clustering GML documents using maximal frequent induced subtree patterns. TBCClustering mines the maximal frequent induced subtrees by using the structural information of GML documents, it can get the best minimum support automatically, and then chooses a set of subtree patterns to form the optimistic clustering features. Finally it uses CLOPE...
A technical framework and relative key techniques to realize a report system based on Three-layer Calculating Architecture are proposed, including metadata mapping and its application, functions of the engine, ETL module, data warehouse and etc. which were designed for this report system. All the techniques studied in this paper have been practiced and have been realized in an actual project of data...
XML query technology has attracted more and more attention in data management research community. Finding all the occurrences of a twig pattern in an XML database is a core operation for XML queries. The previous approaches produce large set of intermediate results when they processing queries with parent-child relationship edges. We propose a new labeling scheme, called extended region encoding labeling...
In this article we describe an approach to the massive production of digital images of manuscripts to be published on the Internet. The goal of this work is to offer an easy-to-use interface that allows customizable views of images manuscript in several sizes and provide searching and browsing functionality for users of Arabic manuscripts using an XML representation for metadata and annotation of...
Traditional databases manage only deterministic information, but now many applications that use databases involve uncertain data. For example, it is infeasible for a sensor database to contain only the exact value of each sensor at all points in time. The uncertainty is inherent in these systems due to measurement and sampling errors, and resource limitations. This paper aims at the query processing...
A purely relational account of the true XQuery semantics can turn any relational database system into an XQuery processor. Compiling nested expressions of the fully compositional XQuery language, however, yields odd algebraic plan shapes featuring scattered distributions of join operators that currently overwhelm commercial SQL query optimizers. This work rewrites such plans before submission to the...
In this paper we present an algorithm for mining of unordered embedded subtrees. This is an important problem for association rule mining from semi-structured documents, and it has important applications in many biomedical, Web and scientific domains. The proposed U3 algorithm is an extension of our general tree model guided (TMG) candidate generation framework and it considers both transaction based...
XML has gained wide popularity for specifying and exchanging data on the WWW. XML is also used to store large amounts of bibliographic and scientific data. However, XML is by nature verbose and this contributes to the fact that XML databases are much large in size, thus increasing the cost for storing and retrieving data in smaller handheld devices which do not have large memory capacity. In order...
With the rapidly increasing popularity of XML as a data format, there is a large demand for efficient techniques in storing and querying XML documents. However XML is by nature verbose, due to repeatedly used tags that describe data. For this reason the storage requirements of XML can be excessive and lead to increased costs for data manipulation. Therefore, it seems natural to use compression techniques...
