An implementation method of automatic metadata extraction method for music data and its application to semantic associative search
Authors: Takashi Kitagawa, Takafumi Nakanishi, Yasushi Kiyoki
Venue: Systems and Computers in Japan (2004)

In this paper, we present a method for implementing a Kansei (sensitivity) operator for an automatic metadata extraction method used for media data. The Kansei operator, which operates on metadata extracted from media data, performs mapping based on human sensitivity by applying a logarithmic function that reflects human sensitivity based on Fechner's law. The proposed method enables metadata that reflects human sensitivity to be extracted according to the Kansei operator for metadata that was obtained according to weighted word categories output by a conventional automatic metadata extraction method. In addition, using a semantic associative search method enables searching to be performed, which matches human intuition for the media data categories. In this paper, we combine the Kansei operator with an automatic metadata extraction method for music data to implement an automatic metadata extraction method having a Kansei operator for music data. In addition, they show the effectiveness of the proposed method experimentally. &copy; 2004 Wiley Periodicals, Inc. Syst Comp Jpn, 35(6): 59&ndash;78, 2004; Published online in Wiley InterScience ().

A Proxy-Network Based Overlay Topology Resistant to DoS Attacks and Partitioning
Authors: Stephen Frechette
Venue: Proceedings of the 19th IEEE International Parallel and Distributed Processing Symposium (IPDPS'05) - Workshop 16 - Volume 17 (2005)

In this paper we examine the effectiveness of a circulant graph proxy-network overlay topology. We select to examine a circulant graph that exhibits several attributes which strengthen the proxy network's resistance to DoS attacks. Proxy networks enable applications to communicate with users without disclosing their IP's. An application's resistance to DoS attacks is improved by hiding it behind a proxy-network based overlay. We evaluate the selected topology's fault-tolerance and its effectiveness in the resistance of DoS attacks.
Direct Measurement of Index Finger Mechanical Impedance at Low Force
Authors: Chia-Yu Fu, Manny Oliver
Venue: Proceedings of the First Joint Eurohaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems (2005)

Non-contact, direct mechanical impedance measurements of the human index finger were performed under sinusoidal force inputs. The force amplitudes from the transducer were from 0.05 N to 0.5 N over the frequency range 50 Hz to 500 Hz, which covers the region of interest for vibrotactile feedback for handheld applications. We found that the vibrational mode of the finger was strongly frequency dependent. Our results indicate that a singledegree-of-freedom of mass-damper-spring model, used previously in impedance models at high finger forces, may not be appropriate at these lower force levels.
Symmetrical Fairness in Infrastructure Access in Multi-hop Wireless Networks
Authors: Saumitra M. Das, Himabindu Pucha, Y. Charlie Hu
Venue: Proceedings of the 25th IEEE International Conference on Distributed Computing Systems (2005)

In this paper, we study the problem of providing fairness in multi-hop wireless infrastructure access. In such networks, it is well known that the use of current media access and transport protocols can result in severe unfairness and even starvation for flows originated from different numbers of hops away from a wired infrastructure point or gateway. In this paper, we study a different type of fairness that exists in such networks ¿ flows initiated by nodes that are similar numbers of hops away from the gateway can experience significant unfairness, and such unfairness exists even for perfectly symmetrical node distribution and channel conditions. We denote such fairness as symmetrical fairness. We first provide a framework to characterize and measure symmetrical fairness. We then perform an extensive set of simulation experiments to quantify the causes of symmetrical unfairness. Finally, we develop and study a distributed routing algorithm that significantly improves the symmetrical fairness.

Random Subspaces and Subsampling for 2-D Face Recognition
Authors: Nitesh V. Chawla, Kevin W. Bowyer
Venue: Proceedings of the 2005 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR'05) - Volume 2 - Volume 02 (2005)

Random subspaces are a popular ensemble construction technique that improves the accuracy of weakclassifiers. It has been shown, in different domains, that random subspaces combined with weak classifiers such as decision trees and nearest neighbor classifiers can provide an improvement in accuracy. In this paper, we apply the random subspace methodology to the 2-D face recognition task. The main goal of the paper is to see if the random subspace methodology can do as well, if not better, than the single classifier constructed on the tuned face space. We also propose the use of a validation set for tuning the face space, to avoid bias in the accuracy estimation. In addition, we also compare the random subspace methodology to an ensemble of subsamples of image data. This work shows that a random subspaces ensemble can outperform a well-tuned single classifier for a typical 2-D face recognition problem. The random subspaces approach has the added advantage of requiring less careful tweaking.

Backup is cumbersome and expensive. Individual users almost never back up their data, and backup is a significant cost in large organizations. This paper presents Pastiche, a simple and inexpensive backup system. Pastiche exploits excess disk capacity to perform peer-to-peer backup with no administrative costs. Each node minimizes storage overhead by selecting peers that share a significant amount of data. It is easy for common installations to find suitable peers, and peers with high overlap can be identified with only hundreds of bytes. Pastiche provides mechanisms for confidentiality, integrity, and detection of failed or malicious peers. A Pastiche prototype suffers only 7.4% overhead for a modified Andrew Benchmark, and restore performance is comparable to cross-machine copy.
Component-based software engineering for embedded systems
Authors: Ivica Crnkovic
Venue: Proceedings of the 27th international conference on Software engineering (2005)

Although attractive, CBD has not been widely adopted in domains of embedded systems. The main reason is inability of these technologies to cope with the important concerns of embedded systems, such as resource constraints, real-time or dependability requirements. However an increasing understanding of principles of CBD makes it possible to utilize these principles in implementation of different component-based models more appropriate for embedded systems. The aim of this tutorial is to point to the opportunity of applying this approach for development and maintenance of embedded systems. The tutorial gives insights into basic principles of CBD, the main concerns and characteristics of embedded systems and possible directions of adaptation of component-based approach for these systems. Different types of embedded systems and approaches for applying CBD are presented and illustrated by examples from research and practices. Also, challenges and research directions of CBD for embedded systems are discussed.
Computational schemes for biomimetic sculpture
Authors: Brower Hatcher, Karl Aspelund, Andrew Willis, Jasper Speicher, David B. Cooper, Frederic F. Leymarie
Venue: Proceedings of the 5th conference on Creativity cognition (2005)

A prototype system for the automatic evolution of biomimetic structures using structural automata is described and its utility for generating digital sculpture is demonstrated. Sculptures are generated from a primordial shape which is represented in terms of a triangular mesh and sculpture is created by extending the original surface using tetrahedral structural elements. Recursively applicable rules or equivalently, automata, are defined which allow the sculptor to generate a volumetric scaffold from the original surface. This scaffold is generated using the stated rules for inserting and connecting together the tetrahedral elements. The software is operated as a generative process where sculptures are grown from an original triangular surface mesh as a sequence of layers. Each layer is created as a 2-step process. In step 1, we populate the surface with tetrahedral structures where the base of each tetrahedron coincides with a surface triangle. Step 2 re-triangulates the apexes of the tetrahedra from step 1 creating an offset and deformed version of the original surface mesh. The sculptor has artistic control of the process at all points and may assign or change rules to generate different biomimetic behaviors, i.e., structures which tend to replicate natural phenomena.
Generic technologies for single- and multi-document summarization
Authors: Marie-Francine Moens, Roxana Angheluta, Jos Dumortier
Venue: Information Processing and Management: an International Journal (2005)

The technologies for single- and multi-document summarization that are described and evaluated in this article can be used on heterogeneous texts for different summarization tasks. They refer to the extraction of important sentences from the documents, compressing the sentences to their essential or relevant content, and detecting redundant content across sentences. The technologies are tested at the Document Understanding Conference, organized by the National Institute of Standards and Technology, USA in 2002 and 2003. The system obtained good to very good results in this competition. We tested our summarization system also on a variety of English Encyclopedia texts and on Dutch magazine articles. The results show that relying on generic linguistic resources and statistical techniques offer a basis for text summarization.

On windows file access modes: a performance study
Authors: Jalil Boukhobza, Claude Timsit
Venue: Proceedings of the 4th international symposium on Information and communication technologies (2005)

This paper deals with file access performance variation measurements and analysis of I/O intensive applications (video on demand, multimedia, data bases for example) accessing large sequential defragmented files on Windows systems. A global performance study on different configurations (different versions of OS, file systems and disk technologies) shows an I/O throughput drop by a factor 3 depending on the request size and up to a factor 10 depending on the specified access mode. We also observed that the global performance pattern remains approximately the same. This lead us to perform more specific and accurate measurements to explain the dramatic performance drops and glitches. We evaluated and identified the exact functioning of the I/O system for the different existing access modes including disk functioning, and file system cache algorithms [9]. Finally, we give programmers guidelines to get optimal performance for Windows I/O system depending on the application constraints'.
Atrial activity extraction from atrial fibrillation episodes based on maximum likelihood source separation
Authors: F. Castells, J. Igual, J. Millet, J. J. Rieta
Venue: Signal Processing (2005)

A novel non-invasive approach for the atrial wave estimation in atrial fibrillation (AF) episodes is presented. The method is based on the maximum likelihood (ML) solution of independent component analysis (ICA). The densities of the bioelectric independent sources corresponding to the ventricular and atrial activities are previously analyzed, and the prior knowledge extracted from them is considered in order to develop an appropriate separation model. As a consequence, the sources can be recovered through the optimization of the ML criterion. The algorithm is validated using a significant database of synthesized and real AF electrocardiograms (ECGs). A simulation model for the generation of realistic AF signals with known AA is also defined. The results show good performance in terms of SNR and correlation indices when estimated AA is compared to known AA. Regarding the real AF ECGs, the AA sources could always be estimated. Successful AA extraction was validated using spectral parameters. The main frequency of the atrial wave ranged from 4.9 to 7.4 Hz, and the spectral concentration was 49.8% on average.
Anaphoric Constraints and Dualities in the Semantics of Nominals
Authors: António Branco
Venue: Journal of Logic, Language and Information (2005)

The grammatical constraints on anaphoric binding, known as binding principles, are observed to form a classical square of oppositions. These constraints are then analysed as the effect of phase quantifiers over reference markers in grammatical obliqueness hierarchies, and the resulting phase quantifiers are shown to be organised in a square of logical duality. The impact of this result on the distinction between quantificational and referential nominals as well as on the logical foundations of the semantics of nominals in general is discussed.
OSCAR on Debian: The EDF Experience
Authors: Geoffroy Vallee, Jean-Yves Berthou, Hugues Prisker, Daniel Leprince
Venue: Proceedings of the 19th International Symposium on High Performance Computing Systems and Applications (2005)

Linux clusters are now an interesting solution to execute numerical simulations. But cluster use implies problems of deployment, because of their distributed architecture. In the past, each company developed his own solution based on various tools. Today, software suites like OSCAR are available and can be freely used. But such solutions may not be adapted to the current computing architecture of companies. For example, the current solution deployed inside a company may be based on a Linux distribution not supported by a software suite like OSCAR. Nevertheless, the use of a software suite like OSCAR is very interesting for companies that are not specialized in cluster management. This paper presents the OSCAR port to the Debian distribution in the context of the numerical simulation platform deployed at Électricité de France (Electricity of France).
Revisiting COTS middleware for DRE systems
Authors: Jeromes Hugues, Laurent Pautet, Fabrice Kordon
Venue: Proceedings of the Eighth IEEE International Symposium on Object-Oriented Real-Time Distributed Computing (2005)

Distributed Real-Time Embedded systems (DRE) increasingly rely on COTS middleware to meet their distribution needs. Yet, there is a technology gap between the design of COTS middleware and the high-integrity constraints of real-time engineering. This puts a limit on the adoption of middleware by system families such as space or avionics. In this paper, we present our current work on the "schizophrenic middleware architecture", a highly tailorable middleware architecture, and its implementation PolyORB. We illustrate how it allows for support of real-time engineering guidelines, enforces determinism, allows for modeling and verification.

Automated markerless extraction of walking people using deformable contour models: Research Articles
Authors: David K. Wagg, Mark S. Nixon
Venue: Computer Animation and Virtual Worlds (2004)

We develop a new automated markerless motion capture system for the analysis of walking people. We employ global evidence gathering techniques guided by biomechanical analysis to robustly extract articulated motion. This forms a basis for new deformable contour models, using local image cues to capture shape and motion at a more detailed level. We extend the greedy snake formulation to include temporal constraints and occlusion modelling, increasing the capability of this technique when dealing with cluttered and self-occluding extraction targets.This approach is evaluated on a large database of indoor and outdoor video data, demonstrating fast and autonomous motion capture for walking people.

The correspondence framework for 3D surface matching algorithms
Authors: B. M. Planitz, A. J. Maeder, J. A. Williams
Venue: Computer Vision and Image Understanding (2005)

Beyond the inherent technical challenges, current research into the three dimensional surface correspondence problem is hampered by a lack of uniform terminology, an abundance of application specific algorithms, and the absence of a consistent model for comparing existing approaches and developing new ones. This paper addresses these challenges by presenting a framework for analysing, comparing, developing, and implementing surface correspondence algorithms. The framework uses five distinct stages to establish correspondence between surfaces. It is general, encompassing a wide variety of existing techniques, and flexible, facilitating the synthesis of new correspondence algorithms. This paper presents a review of existing surface correspondence algorithms, and shows how they fit into the correspondence framework. It also shows how the framework can be used to analyse and compare existing algorithms and develop new algorithms using the framework's modular structure. Six algorithms, four existing and two new, are implemented using the framework. Each implemented algorithm is used to match a number of surface pairs. Results demonstrate that the correspondence framework implementations are faithful implementations of existing algorithms, and that powerful new surface correspondence algorithms can be created.
A communication kernel of a cluster system for distributed simulation
Authors: H. Valchanov, I. Ruskov, N. Ruskova
Venue: Proceedings of the 5th international conference on Computer systems and technologies (2004)

Parallel discrete event simulation (PDES) is a basic approach for evaluation of the complex systems. A PDES attempts to speed up the execution of a simulation by distributing the simulation's workload between multiple processors (DS). A network of workstations is a widely available platform for DS. This paper explores an implementation's details of a communication subsystem for DS. The techniques for reducing of interprocessor communication overload are presented.
Scheduling legacy multimedia applications
Authors: Xin Liu, Steve Goddard
Venue: Journal of Systems and Software (2005)

Millions of applications have been developed on conventional time-sharing systems. We call those applications legacy applications. Many of them, typically multimedia applications, have Quality of Service (QoS) demands, which are not supported in time-sharing systems. Although many scheduling algorithms and schedulers have been proposed to schedule multimedia applications, it is not feasible to rebuild millions of legacy multimedia applications in a completely new programming model. Moreover, the execution pattern of multimedia applications is difficult to predict.This work presents a legacy application-compatible, adaptation-oriented scheduling framework. The new scheduler is implemented as a Linux loadable module. Thus users can either use the original Linux scheduler or use our scheduler by loading the module. In the new scheduler, users can reserve a default execution rate for legacy multimedia applications, and a rate adjustment mechanism is provided for adaptation. The framework also supports rate-based execution (RBE) and periodic threads that run at a constant rate, and non-real-time threads that have no QoS demand.
Toward an integrated digital museum system &#x2013; the Chi Nan experiences
Authors: Jen-Shin Hong, Bai-Hsuan Chen, Sheng-Hao Hung, Jieh Hsiang
Venue: International Journal on Digital Libraries (2005)

The essential activities of a museum are multifaceted and include collection, preservation, research, exhibition, education, and entertainment. Hence, the march toward a full-fledged digital museum must evolve from the digital library concept with the addition of various interactive edutainment modules. In this paper, we describe various phases of the digital museum systems constructed by the National Chi Nan University, Taiwan, over the past few years. The design concepts and integration issues of essential digital museum modules are addressed. We have as our long-term goal the construction of an integrated digital museum that provides digital archives with user-friendly information access interfaces, intriguing virtual exhibitions, adaptive online courseware, and adaptive interactive games. A mechanism to facilitate the implementation of large-scale aesthetic exhibitions has been proposed. Our approach, the fine-grained modularization of aesthetic hypermedia presentations, concerns the balance between the complexity in the authoring process, the aesthetic qualities of final hypermedia presentations, and efforts at style template implementation. Moreover, various experiences and evaluations of content-based image retrieval, online courseware, and online interactive games will also be addressed. Future work toward an integrated digital museum system is proposed. Our digital museums can be accessed at http://dlm.ncnu.edu.tw.
