Recent developments in portable devices and growing wireless communication networks have evolved mobile computing during the last few years. Mobile computing enlarges the usability of computers by allowing low powered mobile devices to query the database over the wireless network, but also raises some demanding challenges such as slow expensive connection, frequent line disconnection, limited host bandwidth, location dependent data etc. This database should not only handle transactions with temporal constraints and maintain consistency, but also use small memory footprint. The database should use the resources more efficiently, port on various operating systems, minimize CPU usage, run for long period of time without any user intervention, secure and flexible enough to work with different applications with no or less tailoring. The database should be generic and can be tailored so that the application designer can get fully functional and flexible database for mobile embedded systems. This paper proposes a mobile embedded database, which will resolve some of the important issues caused by the mobile computing environment using a component based approach.

The explosive growth of XML has led to an increasing need for scalable XML retrieval systems. Our XML retrieval system, the SQLGenerator, stores XML of any schema in a fixed schema relational database and supports a full-featured semistructured query language, XML-QL, through optimized translation of its semantics to relational SQL queries. We examine the scalability of this approach with respect to increasing data size. We index four XML collections ranging in size from 500MB to 2GB that were generated using a standard XML generator, XBench. We then compare the execution times of 11 standard XBench queries, covering a wide range of semistructured query features, whose semantics were directly translatable from their original XQuery language to XML-QL. Although it is difficult to estimate the theoretical baseline for scalability of these query features in an RDBMS, many of the queries' runtimes grow linearly with respect to the size of the document collection.

Fuzzy edge detector using entropy optimization

作者： M. Hanmandlu J. See S. Vasikarla Department of Electrical Engineering Indian Institute of Technology Delhi New Delhi India

This paper proposes a fuzzy-based approach to edge detection in gray-level images. The proposed fuzzy edge detector involves two phases - global contrast intensification and local fuzzy edge detection. In the first phase, a modified Gaussian membership function is chosen to represent each pixel in the fuzzy plane. A global contrast intensification operator, containing three parameters, viz., intensification parameter t, fuzzifier f/sub h/ and the crossover point x/sub c/, is used to enhance the image. The entropy function is optimized to obtain the parameters f/sub h/, and x/sub c/ using the gradient descent function before applying the local edge operator in the second phase. The local edge operator is a generalized Gaussian function containing two exponential parameters, /spl alpha/ and /spl beta/. These parameters are obtained by the similar entropy optimization method. By using the proposed technique, a marked visible improvement in the important edges is observed on various test images over common edge detectors.

Although users of multi-level secure database management system (MLS/DBMS) continue to rely on existing systems to satisfy their multi-level security needs, these systems no longer enjoy direct commercial-off-the-shelf (COTS) support. This calls for a renewed approach to developing MLS/DBMS systems. We advocate fragmentation as a good basis for implementing multi-level security, and to this end we implemented a prototype MLS/DBMS that utilizes the inherent advantages of the distribution scheme in distributed databases for controlling access to single-level fragments. Experiments were instrumented to determine the relative performance of the tuple, attribute, and element level fragmentation schemes. The experiments measured the impact of varying the number of tuples, attributes, security levels, and nodes, for a selection and join query. Overall, our study finds that the attribute level fragmentation scheme demonstrates superior performance to the tuple and element level schemes. The response times (and hence the performance) of the element level fragmentation scheme exhibited the worst performance degradation compared to the tuple and attribute level schemes.

作者： I. Gondra D.R. Heisterkamp Department of Computer Science Oklahoma State University Stillwater OH USA

In previous work, we developed a novel relevance feedback (RF) framework that learns one-class support vector machines (ISVM) from retrieval experience to represent the set memberships of users' high level semantics. By doing a fuzzy classification of a query into the regions of support represented by the ISVMs, past experience is merged with short-term (i.e., intra-query) learning. However, this led to the representation of long-term (i.e., inter-query) learning with a constantly growing number of ISVMs in the feature space. We present an improved version of our earlier work that uses an incremental k-means algorithm to cluster ISVMs. The main advantage of the improved approach is that it is scalable and can accelerate query processing by considering only a small number of cluster representatives, rather than the entire set of accumulated ISVMs. Experimental results against real data sets demonstrate the effectiveness of the proposed method.

In classes supported by electronic messaging systems, students are required or encouraged to discuss the class topics and share their knowledge by posting text messages and replying to others. When the amount of messages is large, it is difficult for the instructor to read through all messages and evaluate student's performance. We apply natural language processing techniques to analyze the course messages to assess student's performance. Students are evaluated from three aspects: knowledge learned from the class, effort devoted to the class, and the activeness of their participation; three measures $keyword density (KD), message length (ML), and message count (MC), are derived from the text messages for each evaluation aspect respectively. The three measures are then combined to compute an overall performance indicator (PI) score for each student. The experiment shows that there is a high correlation between the PI scores and the actual grades; the rank order of students by the PI scores and that by the actual grades are highly correlated as well.

Traditionally backup has been performed on tapes. With the price of disk becoming cheaper and CPUs becoming faster, the use of disk-based network backup system to replace or augment tape-based backup becomes realistic. More interestingly, random access nature of disks allows redundancy of data to be taken into consideration for more efficient network transmissions and data storage at the backup system. In this paper, we consider the type of redundancy that can be exploited and study different types of compression techniques suitable to achieve improved network efficiency and storage efficiency during the backup. One form of redundancy we exploit is the similarities between different versions. Such efficiencies are never before achievable using tape-based solutions. We also implemented a working disk-based network backup system called "A-Backup system", which applies the technologies discussed in the paper. Such a system is capable of achieving over l0x compression in both network utilization and data storage during backup.

A VPN establishes a cryptographically secure network using the existing insecure infrastructure of the Internet. A number of protocols, including IPSec have been designed to establish VPNs. However, keys must be shared between the communicating peers before a VPN can be established. IKE protocol is used for exchanging keys between authenticated peers over the Internet. However, IKE is vulnerable to DoS attacks and has security holes. A number of protocols have been proposed to replace IKE but these protocols also have vulnerabilities of their own. In this paper, we present an analysis of IKE and identify its security holes and design weaknesses. We also propose a more secure and efficient key exchange protocol, Arcanum, and carry out its security analysis and comparison with existing protocols. Arcanum is more secure, robust to DoS attacks and efficient in terms of time and number of messages.

Frequency of attacks on Web services and resulting damage continue to grow as Web services become popular. Unfortunately, existing signature-based intrusion detection techniques are inadequate in providing reasonable degree of Web security. Web attacks are diverse in nature, and typical Web architecture consists of complex and hierarchically organized components. Because attack strategies often vary depending on the Web contents, it is impossible to develop fixed patterns capturing unknown attacks. Protection mechanisms such as anomaly-based intrusion detection and application-level IDS, tailored to Web services, are needed to detect Web attacks. The first step in developing Web application IDS is to analyze and categorize possible Web attacks and vulnerabilities. In this paper, we classify Web attacks by analyzing the root causes and the locations where they occur. This research is useful in developing Web IDS modules, tracking emerging trends on Web attacks, and testing Web applications against potential vulnerabilities.

Nowadays relational database schemas are designed by using well-known database design techniques such as the entity relationship model and the normalization process. The result schemas can be guaranteed to have minimum redundancies if the fifth normal form (5NF) is achieved. However, in more recent database schema design such as the design of object database schema, the concern about minimum redundancies does not seem to be an important issue. Functional dependencies may still appear in an object class of the class diagram thus introduce update anomalies. This article first presents the use of NIAM, a well-established conceptual schema model, as a conceptual model for the design of object databases. A transformation from a NIAM to an OODB schema with minimum redundancy is presented. The conceptual schema can also be transformed into Extensible Markup Language (XML) which is originally a language for document management. However, it now gains popularity in database representation. It is particularly useful as a data format when an application must communicate with another application. This article also presents the NIAM conceptual schema model as a conceptual design tool for XML schema. A software tool that allows users to create NIAM schemas and generate object and XML schemas is developed.
