Traditionally, interlibrary cooperation is an important interaction between libraries. Nevertheless, the emerging digital library architecture has not explicitly supported this requirement. In this paper, we proposed an interlibrary cooperation framework for digital libraries using P2P technology. An application of this framework to Faculty Publication Sharing System was presented. Besides, a reputation model based on data mining is utilized to provide libraries with incentives to join this framework

In this paper, we propose a cooperative control strategy for a group of robotic vehicles to achieve the specified task issued from a high-level astronaut command. The problem is mathematically formulated as designing the cooperative control for a general class of multiple-input-multiple-output (MIMO) dynamical systems in canonical form with arbitrary but finite relative degrees such that the outputs of the overall system converge to the explicitly given steady state. The proposed cooperative control for individual vehicle only need to use the sensed and communicated outputs information from its local neighboring vehicles. No fixed leader and time-invariant communication networks are assumed among vehicles. Particularly, a set of less-restrictive conditions on the connectivity of the sensor/communication networks are established, under which it is rigorously proven by using the newly found nice properties of the convergence of sequences of row stochastic matrices that the cooperative objective of the overall system can be achieved. Simulation results for a group of vehicles achieving a target and surrounding a specified object in formation are provided to support the proposed approach in this paper.

In this paper an efficient user identification scheme based on ID-based cryptosystem is discussed. In this paper, it is indicated that Hwang et al., scheme is vulnerable to the forgery attack. And also improved scheme is quite similar to Hwang et al's scheme; the modified scheme is secure against the attack. The time complexity of computing the parameter a requires just one more modular multiplication operation. Thus, the scheme is not only far more secure but also efficient than Hwang et al's

International Conference on Security and Privacy for Emerging Areas in Communications Networks (SecureComm)

作者： Jianqing Zhang Nikita Borisov William Yurcik Department of Computer Science University of Illinois Urbana-Champaign Urbana IL USA Department of Electrical and Computer Engineering University of Illinois Urbana-Champaign Urbana IL USA National Center for Supercomputing Applications (NCSA) University of Illinois Urbana-Champaign Urbana IL USA

As security monitoring grows both more complicated and more sophisticated, there is an increased demand for outsourcing these tasks to managed security service providers (MSSPs). However, the core problem of sharing private security logs creates a barrier to the widespread adoption of this business model. In this paper we analyze the logs used for security analysis with the concern of privacy and propose the constraints on anonymization of security monitor logs. We believe if the anonymization solution fulfills the constraints, MSSPs can detect the attacks efficiently and protect privacy simultaneously

The Collaborative Large-scale engineering Analysis Network for Environmental Research (CLEANER) Project Office has been established with funding from the National science Foundation (NSF) to the University of Illinois Urbana-Champaign (UIUC) and a coalition of 11 other institutions. The project office is coordinating the creation of a strategic plan consisting of research, cyberinfrastructure, and education plans that set forth a roadmap for the collaborative engineering analysis network for the study of environmental problems. This report will be completed by July 2007 and requires input from K-12 educators, administrators and other stakeholders in K-12 education. This paper describes the CLEANER project, provides an example of the CLEANER Education Committee's vision for the K-12 area and lists contacts for further information. The intention of this paper is to elicit input from the K-12 engineering education community, including K-12 educators, on how the CLEANER Education Plan could better meet the future needs of K-12 students and educators © American Society for engineering Education, 2006.

Coulomb localization and exchange modulation in two-electron coupled quantum dots

Physical Review B 2006年第4期74卷 041309(R)-041309(R)页

Melnikov Jean-Pierre Leburton Ahmed Taha Nahil Sobh Beckman Institute for Advanced Science and Technology & Department of Electrical and Computer Engineering University of Illinois at Urbana-Champaign 401 North Mathews Avenue Urbana Illinois 61801 USA National Center for Supercomputing Applications University of Illinois at Urbana-Champaign 1205 West Clark Street Urbana Illinois 61801 USA

A general study of the singlet-triplet energy separation (exchange energy) in the two-electron system confined in a realistic double-quantum-dot system is performed using a hybrid multiscale approach where the many-body Schrödinger equation is solved exactly within the full quantum dot device environment. The exchange energy is computed as a function of the gate confinement and magnetic field. In particular, it is found that at zero magnetic field the exchange energy varies from meV to sub-μeV values as the confinement gate biases (tunneling barrier) are changed and the system is driven from a single quantum dot to two coupled quantum dots. The small values of the exchange coupling in this structure are attributed to the large interelectron separation arising when the Coulomb repulsion dominates tunneling.

Multidimensional frequent pattern mining using association rule based constraints

Knowledge about multi-dimensional frequent patterns is interesting and useful. The classic frequent pattern mining algorithms based on a uniform minimum support, such as Apriori and FP-growth, either miss interesting patterns of low support or suffer from the bottleneck of itemset generation. Other frequent pattern mining algorithms, such as Adaptive Apriori, though taking various supports, focus mining at a single abstraction level. Furthermore, as an Apriori-based algorithm, the efficiency of Adaptive Apriori suffers from the multiple database scans. In this paper, we extend FP-growth to attack the problem of multidimensional frequent pattern mining. The algorithm Ada-FP, which stands for Adaptive FP-growth. The efficiency of the Ada-FP is guaranteed by the high scalability of FP-growth. To increase the effectiveness, the Ada-FP pushes various support constraints into the mining process. We show that the Ada-FP is more flexible at capturing desired knowledge than previous Algorithm. © Springer-Verlag Berlin Heidelberg 2005.

An enhanced one way function tree rekey protocol based on Chinese remainder theorem

20th International Symposium on computer and Information sciences, ISCIS 2005

Group communication is the basis for many recent multimedia and web applications. The group key management is one of the most critical problems in a large dynamic group. All group rekeying protocols add communication as well as computational overhead at the Group Key Controller (GKC) and group members. The trade off between these overheads depends on different levels of security required for different types of multicast applications [10,12,16]. This proposed work introduces a new key management algorithm based on Chinese reminder theorem (CRT). This algorithm uses CRT tuple of smaller remainders instead of keys of larger bits. So, any computation on these keys is carried out in parallel using remainders. Thus this approach reduces overall computational overhead. This algorithm reduces communication over head during the join event highly without compromising security. © Springer-Verlag Berlin Heidelberg 2005.

Stock market prediction is a complex and tedious task that involves the processing of large amounts of data, that are stored in ever growing databases. The vacillating nature of the stock market requires the use of data mining techniques like clustering for stock market analysis and prediction. Genetic algorithms and neural networks have the ability to handle complex data and are immune to noise in the input. In this paper, we propose a fuzzy based neuro-genetic algorithm - Fuzzy based Evolutionary Approach to Self Organizing Map(FEASOM) to cluster stock market data. Genetic algorithms are used to train the Kohonen network for better and effective prediction. The algorithm was tested on real stock market data of companies like Intel, General Motors, Infosys, Wipro, Microsoft, IBM, etc. The algorithm consistently outperformed regression model, backpropagation algorithm and Kohonen network in predicting the stock market values.
