Information Management (IM) has been an area of research and discussion for several decades. Studies have been conducted by both behavioral and computer scientists on how people organize their information and workspaces in order to come up with an efficient way to store, organize and retrieve information on personal computers. This paper explores improving a user's ability to manage information on mobile devices. The goal is to make placing information on such devices a more attractive prospect, with an emphasis on retrieval of stored information regardless of the document type. This will result in mobile users having quick access to the right information at the right time while away from the office or home. This paper describes the challenges inherent in a mobile scenario and proposes a system to address those challenges. The system provides visual and navigational features that are not currently available on mobile applications, specifically the ability to view multiple types of items in a single interface. Additionally, the ability to logically link related items as an IM tool is examined. Copyright 2007 ACM.

A fuzzy version of an Evolutionary Algorithm for Clustering (EAC) proposed in, previous work is introduced. This algorithm uses a fuzzy cluster validity criterion and a fuzzy local search algorithm instead of their hard counterparts employed by EAC. It is shown by means of theoretical complexity analyses that this algorithm can be more efficient than systematic (i.e. repetitive) approaches when the number of clusters is unknown. An illustrative example with computational experiments and statistical analyses is also presented.

International Journal of Network Management 2007年第4期17卷 287-294页

作者： Da Silva, Paulo Fernando Westphall, Carlos Becker Network and Management Laboratory Post-Graduate Program in Computer Science Federal University of Santa Catarina Florianópolis Brazil

This paper presents a model for response interoperability between intruder detection systems (IDSs), compatible with the model for alert interoperability developed by the Intrusion Detection Working Group (IDWG). Alterations in IDS IDWG architecture are proposed in order to provide for response interoperability support. The development and testing of the proposed model and its components are also presented.

With support from HBCU-UP (Historically Black College and University Undergraduate program) at National science Foundation (NSF), the ACTION (Advanced Curriculum and Technology-Based Instructional Opportunities Network) program at University of Maryland Eastern Shore (UMES) is promoting inquiry based active learning and research projects among undergraduate STEM (science, Technology, Engineering and Mathematics) majors. Field based experiential learning efforts titled (i) AIRSPACES: Aerial Imaging and Remote Sensing for Precision Agriculture and Environmental Stewardship and (ii) ECPA: Environmentally Conscious Precision Agriculture, provided a perfect setting for STEM undergraduates to interact with UMES farm personnel, graduate students, NASA and USDA researchers collaborating with the faculty members in the project. In the summer of 2006 ACTION program supported three undergraduate students to work with the principal author to work on a chosen aspect of the ongoing effort. For this ACTION project students decided to focus on aspects of yield monitoring and remote sensing for the precision agriculture project at UMES. This paper will highlight the student efforts related to the ACTION project for 2006 summer and discuss how the out of classroom, field, and laboratory based activities enhanced learning. © American Society for Engineering Education, 2007.

Chemical reaction networks by which individual cells gather and process information about their chemical environments have been dubbed "signal transduction" networks. Despite this suggestive terminology, there have been few attempts to analyze chemical signaling systems with the quantitative tools of information theory. Gradient sensing in the social amoeba Dictyostelium discoideum is a well characterized signal transduction system in which a cell estimates the direction of a source of diffusing chemoattractant molecules based on the spatiotemporal sequence of ligand-receptor binding events at the cell membrane. Using Monte Carlo techniques (MCell) we construct a simulation in which a collection of individual ligand particles undergoing Brownian diffusion in a three-dimensional volume interact with receptors on the surface of a static amoeboid cell. Adapting a method for estimation of spike train entropies described by Victor (originally due to Kozachenko and Leonenko), we estimate lower bounds on the mutual information between the transmitted signal (direction of ligand source) and the received signal (spatiotemporal pattern of receptor binding/unbinding events). Hence we provide a quantitative framework for addressing the question: how much could the cell know, and when could it know it? We show that the time course of the mutual information between the cell's surface receptors and the (unknown) gradient direction is consistent with experimentally measured cellular response times. We find that the acquisition of directional information depends strongly on the time constant at which the intracellular response is filtered.

Intrusion detection systems (IDSs) have been substantially improved in recent past. However, network attacks have become more sophisticated and increasingly complex: many of current attacks are coordinated and originated in multiple networks. To detect these attacks, IDSs need to obtain information on network events from multiple networks or administrative domains. This work demonstrates that a Distributed IDS (DIDS) can be composed of existing IDSs, improving the detection of misuses in a multiple network environment. We use a grid middleware for creating a service-based intrusion detection grid. We demonstrate through experimental results that the proposed DIDS allows the integration of heterogeneous existing IDSs and improves the detection of attacks by exploring the synergy between existing IDSs.

This paper evaluates how well a significant number of broadcasting protocols for MANETs behave when under a realistic scenario of momentary failures and topology changes, which is represented by an omission fault model. Reliable protocols which use additional mechanisms to ensure higher delivery rates beyond best- effort guarantees - have been proposed, but they exhibit unacceptably high end-to-end delays. As a result of the study conducted, a new mechanism that helps to enhance the reliability of deterministic broadcasting protocols is proposed. The mechanism allows for scalability, and is capable of ensuring good delivery rates (in spite of failures) while maintaining lower end-to-end delays. Simulation results demonstrate the efficacy of the mechanism.

Current mammographic screeningfor breast cancer is less effective for younger women. To complement mammography for premenopausal women, we investigated the feasibility screening test using 98 blood serum proteins. Because the data set was very noisy and contained only weak features, we used a classifier designed for noisy data: decision fusion. Decision fusion outperformed both a support vector machine (SVM) and linear regression with forward stepwise feature selection on all three two-class classification tasks: normal tissue vs. cancer, normal tissue vs. benign lesions, and benign lesions vs. cancer. Decision fusion detected cancer moderately well (AUC=0.84 on normal vs. cancer), demonstrating promise as a screening tool. Decision fusion also detected benign lesions similarly well (AUC=0.83 on normal vs. benign lesions) and was the only classifier to achieve any success in separating benign from malignant lesions (AUC=0.64 on benign vs. cancer). The classification results suggest that the assayed proteins are more indicative of a secondary effect, such as immune response, rather than specific for breast cancer. In conclusion, the decision fusion classifier demonstrated some promise in detecting breast lesions and outperformed other classifiers, especially for the very noisy classification problem of distinguishing benign from malignant lesions. ©2007 IEEE.
