Correspondence: Comments and improved results on "H∞ filtering for discrete-time systems with randomly varying sensor delays"
Authors: Yafeng Guo, Shaoyuan Li
Venue: Automatica (Journal of IFAC) (2009)

This note points out some errors in the main results of Zhou and Feng [Zhou, S., & Feng, G. (2008). H"~ filtering for discrete-time systems with randomly varying sensor delays. Automatica, 44 (7), 1918-1922] and presents the corrected versions of these results. Furthermore, an improved method, which is less conservative than that of Zhou and Feng, is proposed to solve the same problem discussed in the commented paper. A numerical example demonstrates the effectiveness of the proposed method.

Knowledge management in construction companies in the UK
Authors: Reza Esmi, Richard Ennals
Venue: AI Society (2009)

Knowledge management is important in the construction industry, but there is a dramatic gap between rhetoric and reality, highlighting mistaken expectations of technology. We report on a case study of a major construction company. The UK construction industry, with scarce academic qualifications, and limited use of IT, depends on knowledge sharing, and, crucially, on tacit knowledge. Economic crisis presents particular problems, and recent trends in work organization have far-reaching implications. The industry depends on human knowledge, with limited systems support. A shared concern for health and safety provides the surest guarantee of sustainability of both knowledge and the company.
Position Paper: Digital Media Archive for Academic Resources
Authors: Takanari Hayama, Eiji Kawaguchi, Yasushi Kiyoki
Venue: Proceeding of the 2006 conference on Information Modelling and Knowledge Bases XVII (2006)

Today, there is high demand for digital media archives that can archive wide variety of academic resources and deliver customized contents upon audiences' needs. Key challenges of the digital media archives for academic resources are a) a methodology to embed academically meaningful interpretation of resources, i.e. metadata, to digital media data themselves b) search mechanism to such academic metadata, and c) sophisticated access methodology to such digital archives. In this position paper, we describe our approach to these challenges, and how we're going to implement the digital media archives in our project.

Who Says Three's a Crowd? Using a Cognitive Tutor to Support Peer Tutoring
Authors: Erin Walker, Bruce M. McLaren, Nikol Rummel, Ken Koedinger
Venue: Proceeding of the 2007 conference on Artificial Intelligence in Education: Building Technology Rich Learning Contexts That Work (2007)

Adding student collaboration to an intelligent tutoring system could leverage the benefits of both approaches. We have incorporated a mutual peer tutoring script, where students of similar abilities take turns tutoring each other, into the Cognitive Tutor Algebra. In this paper, we identify three design principles for peer tutoring, and discuss how they were realized in our peer tutoring script. We then develop a cognitive model for peer tutoring, and drawing from student data, identify places for an intelligent tutor to provide feedback. Finally, we describe the implementation of the script and our plans for formal evaluation.
Monocular object pose computation with the foveal-peripheral camera of the humanoid robot Armar-III
Authors: Guillem Alenyà, Carme Torras
Venue: Proceeding of the 2008 conference on Artificial Intelligence Research and Development: Proceedings of the 11th International Conference of the Catalan Association for Artificial Intelligence (2008)

Active contour modelling is useful to fit non-textured objects, and algorithms have been developed to recover the motion of an object and its uncertainty. Here we show that these algorithms can be used also with point features matched in textured objects, and that active contours and point matches complement in a natural way. In the same manner we also show that depth-from-zoom algorithms, developed for zooming cameras, can be exploited also in the foveal-peripheral eye configuration present in the Armar-III humanoid robot.
iSCSI protocol adaptation with 2-way TCP Hand Shake mechanism for an embedded multi-agent based health care system
Authors: Shaikh Muhammad Allayear, Sung Soon Park, Jaechun No
Venue: Proceedings of the 10th WSEAS international conference on Mathematical methods, computational techniques and intelligent systems (2008)

In this paper we have proposed a parameter-evaluated iSCSI protocol that automates the multi-agent coordination on the resource-constrained devices for the healthcare service. The coordination between the resource control devices and automated agents are maintained by a two-way handshaking mode iSCSI with some evaluated parameters. The automated healthcare control could be useable and beneficial in the repetitive way. A fully centralized control is not applicable for this kind of approach.
Graphical Notation for Diagramming Coupled Systems
Authors: J. Walter Larson
Venue: Proceedings of the 9th International Conference on Computational Science: Part I (2009)

Multiphysics and multiscale---or coupled---systems share one fundamental requirement: Construction of coupling mechanisms to implement complex data exchanges between a system's constituent models. I have created a graphical schema for describing coupling workflows that is based on a theoretical framework for describing coupled systems. The schema combines an expanded set of traditional flowchart symbols with pictograms representing data states. The data pictograms include distributed mesh, field, and domain decomposition descriptors and spatiotemporal integration and accumulation registers. Communications pictograms include: blocking- and non-blocking point-to-point and M ×N parallel data transfer; parallel data transposes; collective broadcast, scatter, gather, reduction and barrier operators. The transformation pictograms include: intergrid interpolation; spatiotemporal integral operators for accumulation of state and flux data; and weighted merging of output data from multiple source models for input to a destination model. I apply the schema to simple problems illustrating real situations in coupler design and implementation. The ACM Portal is published by the Association for Computing Machinery.

FCA-Based Two Dimensional Pattern Matching
Authors: Fritz Venter, Derrick G. Kourie, Bruce W. Watson
Venue: Proceedings of the 7th International Conference on Formal Concept Analysis (2009)

We propose a concept lattice-based approach to multiple two dimensional pattern matching problems. It is assumed that a pattern can be described as a set of vertices (or pixels) and that a small set of vertices around each vertex corresponds to an attribute in a concept lattice. Typically, an attribute should be a succinct characterisation of domain-dependent relevant information about the neighbourhood of the vertex. The set of objects in the lattice is the set of 2D patterns to be matched. Searching in the 2D image is carried out in reference to the intents of lattice concepts. Thus, by searching a small region of the text, one can efficiently identify which sets of pattern objects may potentially be found in a larger environment of that region. As experimental data, we use 2D images derived from microchip design layouts and 2D matching patterns derived from microchip design rules.

Reducing handover latency in future IP-based wireless networks: proxy mobile IPv6 with simultaneous bindings
Authors: Mortaza S. Bargh, Bob Hulsebosch, Henk Eertink, Geert Heijenk, Jeroen Idserda, Julien Laganier, Anand R. Prasad, Alf Zugenmaier
Venue: Proceedings of the 2008 International Symposium on a World of Wireless, Mobile and Multimedia Networks (2008)

Handover in future wireless communication systems must be seamless. Current IP-level mobility protocols have difficulties meeting the stringent handover delay requirements. At the same time they do not give sufficient control to the network to optimize the handover process and they do not deal well with slow connection setups of some wireless technologies. In this paper we propose an enhancement of Proxy MIPv6 (PMIPv6) with Simultaneous bindings. The result, called SPMIPv6, is a proactive network-controlled handover solution that allows some handover processes to be carried proactively while the mobile node is connected to the serving network. We analyze SPMIPv6 performance and show that the handover latency can be limited to one RTT between the mobile node and the target access router, which is typically below 10ms, and that the packet loss due to handover can be decreased and eliminated by appropriately buffering packets at the target access router. Moreover, our performance evaluation based on a SPMIPv6 implementation shows no TCP and UDP performance degradation during handovers. Two important characteristics of SPMIPv6 are its robustness to incorrect handover predictions and its built-in features to accommodate large network attachment latencies.
Optimizing availability and QoS of heterogeneous distributed system based on residual lifetime in uncertain environment
Authors: Chuang Lin, Xin Jiang, Hao Yin, Yuanzhuo Wang, Yada Hu, Binbin Xiong
Venue: The Journal of Supercomputing (2009)

A notable requirement of heterogeneous parallel and distributed computing systems is to maximize their processing performance and agreed upon QoS. Lots of work in this field has been done to optimize the system performance by improving certain metrics such as reliability, robustness, security, and so on. However, most of them assume that systems are running without interruption all the time and seldom consider the system's intrinsic characteristics, such as failure rate, repair rate, and lifetime. In this paper, we study how to achieve high availability based on residual lifetime analysis for heterogeneous distributed computational systems with considering their essential features. First, we provide an availability model taking into account system's expected residual lifetime. Second, we propose an objective function about the model and develop a heuristic scheduling algorithm to maximize the availability with the makespan constraint. At last, we demonstrate these advantages through the extensive simulated experiments.
Visualizing & exploring networks using semantic substrates
Authors: Ben Shneiderman
Venue:  (2008)

Visualizing and exploring network data has been a challenging problem for HCI (Human-Computer Interaction) Information Visualization researchers due to the complexity of representing networks (graphs).Research in this area has concentrated on improving the visual organization of nodes and links according to graph drawing aesthetics criteria, such as minimizing link crossings and the longest link length. Semantic substrates offer a different approach by which node locations represent node attributes. Users define semantic substrates for a given dataset according to the dataset characteristics and the questions, needs, and tasks of users. The substrates are typically 2&ndash;5 non-overlapping rectangular regions that meaningfully lay out the nodes of the network, based on the node attributes. Link visibility filters are provided to enable users to limit link visibility to those within or across regions. The reduced clutter and visibility of only selected links are designed to help users find meaningful relationships.This dissertation presents 5 detailed case studies (3 long-term and 2 short-term) that report on sessions with professional users working on their own datasets using successive versions of the NVSS (Network Visualization by Semantic Substrates, http://www.cs.umd.edu/hcil/nvss) software tool. Applications include legal precedent (with court cases citing one another), food-web (predator-prey relationships) data, scholarly paper citations, and U.S. Senate voting patterns. These case studies, which had networks of up to 4,296 nodes and 16,385 links, helped refine NVSS and the semantic substrate approach, as well as understand its limitations. The case study approach enabled users to gain insights and form hypotheses about their data, while providing guidance for NVSS revisions. The proposed guidelines for semantic substrate definitions are potentially applicable to other datasets such as social networks, business networks, and email communication. NVSS appears to be an effective tool because it offers a user-controlled and understandable method of exploring networks. The main contributions of this dissertation include the extensive exploration of semantic substrates, implementation of software to define substrates, guidelines to design good substrates, and case studies to illustrate the applicability of the approach to various domains and its benefits.
Computational modeling approaches help guide early design efforts for usability
Authors: Maria Vicente Bonto-Kane, Robert St. Amant
Venue: The Fifth Richard Tapia Celebration of Diversity in Computing Conference: Intellect, Initiatives, Insight, and Innovations (2009)

In this paper, we describe the innovative approach of using formal computational models to guide design efforts and evaluate software interfaces for usability. Decades of work in the field of HCI looked to using task analyses, live user testing and GOMS modeling techniques to help design for usability. While these methods proved helpful, guidance came after the fact. Only after the prototype interface had been designed were the traditional techniques useful in evaluating the interface. This research seeks to be innovative in two ways. First, it seeks to examine techniques that can directly impact design at the very first stages where it is most critical. Second, it demonstrates the utility of a not so often used approach, that of using formal computational models to impact design. In this research, formal computational models were used to map sequences of operations of an activity or task. A candidate interface was then designed around the formal model's recommendations for what would be most facilitative for this activity. The result was an interface that performed optimally per model predictions. Additionally, live user testing was employed and empirical observations verified and reinforced the model predictions.

Evaluation of Hierarchical Mesh Reorderings
Authors: Michelle Mills Strout, Nissa Osheim, Dave Rostron, Paul D. Hovland, Alex Pothen
Venue: Proceedings of the 9th International Conference on Computational Science: Part I (2009)

Irregular and sparse scientific computing programs frequently experience performance losses due to inefficient use of the memory system in most machines. Previous work has shown that, for a graph model, performing a partitioning and then reordering within each partition improves performance. More recent work has shown that reordering heuristics based on a hypergraph model result in better reorderings than those based on a graph model. This paper studies the effects of hierarchical reordering strategies within the hypergraph model. In our experiments, the reorderings are applied to the nodes and elements of tetrahedral meshes, which are inputs to a mesh optimization application. We show that cache performance degrades over time with consecutive packing, but not with breadth-first ordering, and that hierarchical reorderings involving hypergraph partitioning followed by consecutive packing or breadth-first orderings in each partition improve overall execution time.

Authors: Haitham J. Taha, M. F. M. Salleh
Venue: WSEAS TRANSACTIONS on COMMUNICATIONS (2009)

The next generation wireless communications systems require higher data rates transmission in order to meet the higher demand of quality services. Research in wireless digital communications techniques have been expending very rapidly in the last few decades, resulting more reliable wireless communication systems that operate at higher spectral efficiency. Since there have been an increased in demand for higher data rate transmission, the systems are incorporating the multi-carrier transmission techniques. Therefore, Orthogonal Frequency Division Multiplexing (OFDM) is one of the leading candidates for future wireless systems. The objective of the paper is to provide a survey on multi-carrier transmission techniques i.e. OFDM and the combination of OFDM with Code Division Multiple Access (CDMA). The review on this rapidly expending area of wireless communication field is carried out on research works for the past 15 years. And in this survey also we Trying to explain how to use Discrete Wavelet Transform based OFDM (DWT-OFDM) Instead of using Fast Fourier Transform based OFDM Fast Fourier Transform based OFDM (FFT-OFDM). This study outlines the state-of-the art of OFDM novel technique as well as the methods of multi-carrier - Code Division Multiple Access (MC-CDMA) and MC-Direct Sequence-CDMA (MC-DS-CDMA).
The school subject information technology: a South African perspective
Authors: Marietjie Havenga, Elsa Mentz
Venue: Proceedings of the 2009 Annual Conference of the Southern African Computer Lecturers' Association (2009)

In this paper our presupposition is that the content knowledge of the school subject Information Technology (IT) is beyond the expected depth of Grade 12 learners. We demonstrate our presupposition by indicating different concerns from principals, teachers and learners. We show that learners have not achieved the stated outcomes as specified in the National Curriculum Statement and Learning Programme Guidelines. In addition, we compare the United Kingdom's leading award body for A-Level qualifications for Computing with the IT content framework of South Africa. We recommend a revision of the content framework to accommodate all learners and equip them with a more balanced knowledge base of the subject field.
A Method of Automatic Metadata Extraction Corresponding to the Impression by Sound of the Words
Authors: Hidenori Homma, Takafumi Nakanishi, Takashi Kitagawa
Venue: Proceeding of the 2007 conference on Information Modelling and Knowledge Bases XVIII (2007)

In this paper, we propose a method of automatic metadata extraction corresponding to impressions of the word's sounds. Generally, a word and a phrase evoke various impressions. The impressions are evoked by not only the semantics of the word but also its sound. Especially, sounds of words are important to understand mutual emotion effectively in our communication. In order to realize search corresponding to the impression of words, it is important that we realize extraction function based on impressions for the sounds of arbitrary words. The correlation relationships between impressions and sounds in Japanese are indicated by this research called “Onso” which means the aspect of sound in Japanese. This method realizes extraction of metadata corresponding to impressions by the sound of the words utilizing the research of “Onso”. We can realize the semantic associative search for impression of the sounds of arbitrary words by applying this method.
