International Conference on Autonomic Computing (ICAC)

Adaptable applications are difficult to develop and maintain especially if adaptive code, which implements the adaptive behavior, is tangled into functional code, which implements the imperative behavior. Our work investigates how to wrap existing applications transparently to generate such management components. Developing manageable components requires some mechanism to support adaptation in behavior. The predominant mechanism for implementing adaptation in object-oriented software is behavioral reflection, which can be used to modify how an object responds to a message. This work describes the application of TRAP/J to a multicast audio application. The audio-streaming application (ASA) is designed to deliver interactive audio from a microphone at one network node to multiple receiving nodes.

Peculiarity rules are a new type of interesting rules which can be discovered by searching the relevance among peculiar data. A main task of mining peculiarity rules is the identification of peculiarity. Traditional methods of finding peculiar data are attribute-based approaches. This paper extends peculiarity oriented mining to relational peculiarity oriented mining. Peculiar data are identified on record level, and peculiar rules are mined and explained in a relational mining framework. The results from preliminary experiments show that relational peculiarity oriented mining is very effective. © 2004 IEEE.

Approximate caches for packet classification

IEEE Annual Joint Conference: INFOCOM, IEEE computer and Communications Societies

Many network devices such as routers and firewalls employ caches to take advantage of temporal locality of packet headers in order to speed up packet processing decisions. Traditionally, cache designs trade off time and space with the goal of balancing the overall cost and performance of the device. We examine another axis of the design space that has not been previously considered: accuracy. In particular, we quantify the benefits of relaxing the accuracy of the cache on the cost and performance of packet classification caches. Our cache design is based on the popular Bloom filter data structure. This paper provides a model for optimizing Bloom filters for this purpose, as well as extensions to the data structure to support graceful aging, bounded misclassification rates, and multiple binary predicates. Given this, we show that such caches can provide nearly an order of magnitude cost savings at the expense of misclassifying one billionth of packets for IPv6-based caches.

An authorization model for multimedia digital libraries

International Journal on Digital Libraries 2004年第3期4卷 139-155页

作者： Kodali, Naren Farkas, Csilla Wijesekera, Duminda Department of Information and Software Engineering George Mason University Fairfax VA 22030-4444 United States Center for Secure Information Systems George Mason University Fairfax VA 22030-4444 United States Information Security Laboratory University of South Carolina Columbia SC 29208 United States Department of Computer Science and Engineering University of South Carolina Columbia SC 29208 United States

In this paper we present a generalized authorization model for multimedia digital libraries. Our aim is to support the enforcement of access control requirements of the original data sources without the need to create a new, unified model for the digital library. We integrate the three most widely used access control models (i.e., mandatory, discretionary, and role-based) within a single framework, allowing seamless accesses to data protected by these security models. In particular, we address the access control needs of continuous media data while supporting quality of service (QoS) requirements and preserving operational semantics. The technical core of the paper focuses on the development of metadata and the corresponding metastructure to represent authorization policies and QoS requirements and shows their applicabilty to continuous media. We define our security objects based on the Synchronized Multimedia Integration Language (SMIL), which controls multimedia presentations. Following the synchronization constructs 〈par〉 and 〈seq〉 of SMIL, we define a normal form for multimedia streams, called SMIL normal form. SMIL normal form provides a syntax-independent representation of semantically equivalent multimedia data. SMIL normal form compositions are extended (decorated) with RDF statements, representing security and QoS metadata. Interpretation of these statements and, therefore, the authorization and QoS requirements of the decorated multimedia object are defined by the metastructure, represented as a DAML+OIL ontology. We propose the concept of generalized subject that encompasses all access permissions of a given user regardless of the multiple permissions in different access control models. Finally, we develop methods to generate secure views for each generalized subject and retrieve them using a secure multimedia server. © Springer-Verlag 2004.

TMS (Targeted Marketing System) is an integrated system and toolkit for profit-driven and cost-effective marketing. The system consists of three components: a Web-based user interface, a market value inference engine, and a presentation and evaluation module. It supports marketing decision making for a company or an organization by combining results from information retrieval, data mining, information theory, and utility theory.

The accuracy of concrete strength inspection has a great influence on the safety evaluation of the building. In order to increase the accuracy, Fuzzy Neural Network (FNN) was built up to evaluate concrete stmngth: It takes full advantage of the characteristics of the common concrete testing methods: drill and rebound, and the abilities of FNN including automatic learning, generation and fuzzy logic inference. The experiment shows that the max relative error of the predicted results is 1.12%, which is satisfied with the requirements of the engineering. The method effieieatly maps the complex non-linear relationship between the drill values and the rebound values, and provides a efficient way for the concrete strength inspection and evaluation.

This work presents a modular hybrid timed Petri net (MHTPN) methodology used to study multi-operational production systems in which parts are used for the production of different product types. This research generalizes work presented in Tsinarakis, GJ et al., (2003) that studied production systems where all parts of the same type were used for the production of a type of final products following a common route. 3 fundamental system modules are derived; their MHTPN models are defined, followed by modules synthesis to obtain the overall system Petri net. For any topology, system's nodes and invariants are calculated. Applicability of the method is illustrated through an analytical example.

This paper gives contribution to the construction of an image mosaic by pasting together a sequence of photographs taken by a regular digital camera from the same position but in different directions. In order to find the best match between two overlapping images, a fuzzy-genetic based algorithm is presented. A translation vector with a minimal difference between the common picture parts has to be found. The difference is defined using the fuzzyfied contours of each images. The search of the optimal translation is considered as a minimization process. This paper proposes a method that uses genetic algorithms to find the minimum point corresponding to the optimal translation. Using the fuzzy based comparison of the two images yields a fast fitness function, while the implementation of the proposed method in a genetic hardware has a low and variable computational cost. The precision of the method is inverse-proportional with the computational time, which makes it ideal to be used in real time systems.

This paper presents the design and experimental results of a Micro Power Generator (MPG) which harvests mechanical energy from its environment and converts this energy into useful electrical power. The energy transduction component is mainly a magnet and a resonating spring made using SU-8 molding and MEMS electroplating technologies. We have shown that when the MPG is packaged into an AA battery size container along with a power-management circuit that consists of rectifiers and a capacitor, it is capable of producing ~1.6 V DC when charged for less than 1 min. Our goal is to realize a MPG to function with low input mechanical frequencies while producing enough power for low-power wireless applications.
