Dynamic Web Content Filtering based on User's Knowledge
Authors: N. Churcharoenkrung, Y. S. Kim, B. H. Kang
Venue: Proceedings of the International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume I - Volume 01 (2005)

This paper focuses on the development of a maintainable information filtering system. The simple and efficient solution to this problem is to block the Web sites by URL, including IP address. However, it is not efficient for unknown Web sites and it is difficult to obtain complete block list. Content based filtering is suggested to overcome this problem as an additional strategy of URL filtering. The manual rule based method is widely applied in current content filtering systems, but they overlook the knowledge acquisition bottleneck problems. To solve this problem, we employed the Multiple Classification Ripple-Down Rules (MCRDR) knowledge acquisition method, which allows the domain expert to maintain the knowledge base without the help of knowledge engineers. Throughout this study, we will prove the MCRDR based information filtering system can easily prevent unknown Web information from being delivered and easily maintain the knowledge base for the filtering system.
The design of the IPACS distributed software architecture
Authors: Heinz Kredel, Matthias Merz
Venue: Proceedings of the 2004 international symposium on Information and communication technologies (2004)

The IPACS-project (Integrated Performance Analysis of Computer Systems) was founded by the Federal Department of Education, Science, Research and Technology (BMBF) in the program High-Performance-Computing to define a new standard for measuring system performance. One part of this research project is the design of a distributed architecture for execution of benchmarks on High Performance Computers. Its objective is to guide benchmarkers along a mostly automated benchmarking process cycle in compiling and executing benchmarks, and finally gathering and presenting the measured results on a central website. In this paper we present a distributed software architecture which allows immediate analysis of the results, is robust and flexible to support this benchmarking process for the benchmark community.
Implementation of a model-centric web application framework with J2EE
Authors: Ralf Gitzel, Markus Aleksy
Venue: Proceedings of the 3rd international symposium on Principles and practice of programming in Java (2004)

While there are currently many open source web application frameworks available to the Java world, none of them are oriented towards the established web design methodologies such as OOHDM [1] or RMM [2]. Some while ago, we introduced the COBANA framework [3], which was designed to fill this gap. In this paper we describe the implementation details, focusing on those problems which are unique to this approach as opposed to other frameworks.
Context-aware middleware for mobile multimedia applications
Authors: Oleg Davidyuk, Jukka Riekki, Ville-Mikko Rautio, Junzhao Sun
Venue: Proceedings of the 3rd international conference on Mobile and ubiquitous multimedia (2004)

We present a context-aware middleware for mobile multimedia applications. The middleware offers functionality for service discovery, asynchronous messaging, publish/subscribe event management, storing and management of context information, building the user interface, and handling the local and network resources. It supports a wide range of context information including location, time, and user's preferences. Further, it allows controlling the connectivity of the device; the middleware is capable of switching traffic from one network connection to another. It can locate the services and software components as well. It facilitates development of multimedia applications by handling such functions as capture and rendering, storing, retrieving and adapting of media content to various mobile devices. The middleware offers facilities for media alerts, which are multimedia messages that are generated when predefined context is recognized. With these capabilities, it enables development of complex context-aware multimedia applications for mobile devices.
Performance by unified model analysis (PUMA)
Authors: Murray Woodside, Dorina C. Petriu, Dorin B. Petriu, Hui Shen, Toqeer Israr, Jose Merseguer
Venue: Proceedings of the 5th international workshop on Software and performance (2005)

Evaluation of non-functional properties of a design (such as performance, dependability, security, etc.) can be enabled by design annotations specific to the property to be evaluated. Performance properties, for instance, can be annotated on UML designs by using the "UML Profile for Schedulability, Performance and Time (SPT)". However the communication between the design description in UML and the tools used for non-functional properties evaluation requires support, particularly for performance where there are many alternative performance analysis tools that might be applied. This paper describes a tool architecture called PUMA, which provides a unified interface between different kinds of design information and different kinds of performance models, for example Markov models, stochastic Petri nets and process algebras, queues and layered queues.The paper concentrates on the creation of performance models. The unified interface of PUMA is centered on an intermediate model called Core Scenario Model (CSM), which is extracted from the annotated design model. Experience shows that CSM is also necessary for cleaning and auditing the design information, and providing default interpretations in case it is incomplete, before creating a performance model.

On the gray-level central and absolute central moments and the mass center of the gray-level variability in low-level image processing
Authors: M. Demi
Venue: Computer Vision and Image Understanding (2005)

The gray-level moments are usually used in image processing literature to describe how the gray-levels of a finite domain of the image are distributed with respect to the mean level. However, the gray-level central and absolute central moments can provide zero-crossings and ridges, respectively, at gray-level discontinuities as well as conventional operators like the Laplacian of Gaussian and the gradient of Gaussian. A mass center b of the gray-level variability can be also defined. When given a starting point p, vector b indicates the path which joins p to the nearest gray-level discontinuity. Moreover, when a moment of even order is used, vector b can indicate a point which is closer to the discontinuity than p regardless of the distance between p and the discontinuity. Therefore, given an approximate starting contour, a discontinuity can be located by iteratively computing the mass centers of the points of the starting contour.
Extracting semantic structure of web documents using content and visual information
Authors: Rupesh R. Mehta, Pabitra Mitra, Harish Karnick
Venue: Special interest tracks and posters of the 14th international conference on World Wide Web (2005)

This work aims to provide a page segmentation algorithm which uses both visual and content information to extract the semantic structure of a web page. The visual information is utilized using the VIPS algorithm and the content information using a pre-trained Naive Bayes classifier. The output of the algorithm is a semantic structure tree whose leaves represent segments having unique topic. However contents of the leaf segments may possibly be physically distributed in the web page. This structure can be useful in many web applications like information retrieval, information extraction and automatic web page adaptation. This algorithm is expected to outperform other existing page segmentation algorithms since it utilizes both content and visual information.
Using visual tags to bypass Bluetooth device discovery
Authors: David Scott, Richard Sharp, Anil Madhavapeddy, Eben Upton
Venue: ACM SIGMOBILE Mobile Computing and Communications Review (2005)

One factor that has limited the use of Bluetooth as a networking technology for publicly accessible mobile services is the way in which it handles Device Discovery. Establishing a Bluetooth connection between two devices that have not seen each other before is slow and, from a usability perspective, often awkward. In this paper we present the implementation of an end-to-end Bluetooth-based mobile service framework designed specifically to address this issue. Rather than using the standard Bluetooth Device Discovery model to detect nearby mobile services, our system relies on machine-readable visual tags for out-of-band device and service selection. Our work is motivated by the recent proliferation of cameraphones and PDAs with built-in cameras. We have implemented the described framework completely for Nokia Series 60 cameraphones and demonstrated that our tag-based connection-establishment technique (i) offers order of magnitude time improvements over the standard Bluetooth Device Discovery model; and (ii) is significantly easier to use in a variety of realistic scenarios. Our implementation is available for free download.
Eye Gaze Tracking under Natural Head Movements
Authors: Zhiwei Zhu, Qiang Ji
Venue: Proceedings of the 2005 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR'05) - Volume 1 - Volume 01 (2005)

Most available remote eye gaze trackers based on Pupil Center Corneal Reflection (PCCR) technique have two characteristics that prevent them from being widely used as an important computer input device for human computer interaction. First, they must often be calibrated repeatedly for each individual; Second, they have low tolerance for head movements and require the user to hold the head uncomfortably still. In this paper, we propose a novel solution for the classical PCCR technique that will simplify the calibration procedure and allow free head movements. The core of our method is to analytically obtain a head mapping function to compensate head movement. Specifically, the head mapping function allows to automatically map the eye movement measurement under an arbitrary head position to a reference head position so that the gaze can be estimated from the mapped eye measurement with respect to the reference head position. Furthermore, our method minimizes the calibration procedure to only one time for each individual. Our proposed method will significantly improve the usability of the eye gaze tracking technology, which is a major step for eye tracker to be accepted as a natural computer input device.
Perceptual and Biomechanical Frequency Response of Human Skin Implication for Design of Tactile Displays
Authors: Ki-Uk Kyung, Minseung Ahn, Dong-Soo Kwon, Mandayam A. Srinivasan
Venue: Proceedings of the First Joint Eurohaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems (2005)

This paper investigates spatiotemporal tactile perceptive characteristics and biomechanical properties of human skin and considers their implications for the design of tactile displays. Three separate experiments were conducted. First, we measured vibrotactile thresholds as a function of frequency of vibration, using a cylindrical contactor of 0.7mm diameter. The results of our experiment showed similar trends to that of previous physiological results that used a larger contactor. In the second experiment, vibrotactile spatial acuities were investigated. Two-point localization errors were measured on the tip of the index finger and on thenar eminence as a function of frequency of vibration. The results show that human skin is sensitive to spatial differences at the frequency bands of 1-3Hz and 18-32Hz. The subjectsý spatial acuities gradually decreased as the frequency of vibration increased over 50Hz. In the third experiment, impedances of human skin were measured as a function of frequency of vibration. From these results, we discuss the implications in the designing of spatially distributed tactile displays and methods for texture display.
The Coffman-Graham Algorithm Optimally Solves UET Task Systems with Overinterval Orders
Authors: Marc Chardon, Aziz Moukrim
Venue: SIAM Journal on Discrete Mathematics (2005)

Scheduling of unit execution time (UET) task systems on parallel machines with minimal schedule length is known to be NP-complete. The problem is polynomially solvable for some special cases. For a fixed number of parallel machines m > 2, the complexity of the problem is still open, but the problem becomes NP-hard if m is arbitrary. In this paper we characterize a new order class that properly contains quasi-interval orders and we prove that the Coffman--Graham algorithm yields optimal schedules for this new class on any number of machines. Finally, some extensions are discussed for a larger order class and for scheduling in the presence of unit communication delays.
Analysis of difference of primes
Authors: Scott Richard McCarthy
Venue: Journal of Computing Sciences in Colleges (2004)

While researching mathematical aspects cryptography we created methods on finding primes, with the initial premise of making an efficient algorithm for finding primes. While finding the primes we started to make a set of primes ordered from the set of primes that we already had found. This second order of primes is what we are basing this investigation on. While this was unique, we found more interesting results by comparing the difference of primes of the second order prime set and the initial prime set. We graphed the results of primes up to 400,000,000. We graphed the occurrences of the set of differences. The ACM Portal is published by the Association for Computing Machinery.

Misalignment estimation and compensation for robotic assembly with uncertainty
Authors: J. Y. Kim, W. S. Kim, H. S. Cho
Venue: Robotica (2005)

The complexity and uncertainty of the cross-sectional shape of the parts to be mated is one of the main reasons that misalignment between them occurs in assembly processes. Misalignment cannot only give rise to assembly failure but also cause damage to the parts or a robot due to large contact force. Therefore, misalignment sensing and compensation is essential for successful assembly operation. In this paper, we propose a novel misalignment estimation and compensation method which does not need any advance information on the cross-sectional shapes of the mating parts. This method utilizes a $\varphi-r$ transformation and an M-estimation pattern matching technique with misalignment images of a peg and a hole taken by an omni-directional visual sensing system during assembly. At every sampling instant during assembly action, it furnishes information on the relative position and orientation between the mating parts, and thus helps to estimate and compensate any possible misalignment between them. Also, a series of experiments are performed with a couple of peg-in-hole tasks, and the results are discussed. The experimental results show that the proposed method is effective for misalignment compensation in robotic assembly even though there is no prior information on part geometry and the images are very noisy.
Overcoming Test Setup Limitations by Applying Model-Based Testing to High-Precision ADCs
Authors: Carsten Wegener, Michael Peter Kennedy
Venue: Journal of Electronic Testing: Theory and Applications (2005)

Test setup limitations, such as noise and parasitics, increasingly impede repeatable and accurate linearity measurements in high-volume production testing of high-precision data converters. Model-based testing has been shown to reduce the adverse effects of noise [14].In this work, we present two enhancements of the linear model-based approach: one is a change of the modeling strategy in order to account for measurement errors induced, for example, by parasitics associated with the device contactor, and another is a Design-for-Test feature that significantly improves the model's ability to reduce the effect of measurement noise on the accuracy of the test outcome.
SRAMT: a hybrid sender and receiver-based adaptation scheme for TCP friendly multicast transmission
Authors: Ch. Bouras, A. Gkamas
Venue: Computer Networks and ISDN Systems (2005)

In this paper, we describe a hybrid sender and receiver-based adaptation scheme for multicast transmission of multimedia data, which we call SRAMT (Sender-Receiver based Adaptation scheme for Multicast Transmission). The most prominent features of SRAMT are its distributed (to sender and receivers) transmission rate estimation algorithm and its innovative RTT (Round Trip Time) estimation algorithm based on one-way delay measurements. With the use of SRAMT, we ensure that sender will transmit TCP friendly traffic and receivers with different capabilities (in terms of available bandwidth) are able to receive the multimedia information. We evaluate SRAMT through a number of simulations and compare it with other schemes available to the literature. Main target of the simulations was the examination of SRAMT behavior to a heterogeneous group of receivers and its behavior against TCP connections.
The Effect of Quantization and Coulomb Friction on the Stability of Haptic Rendering
Authors: Nicola Diolaiti, Gunter Niemeyer, Federico Barbagli, J. Kenneth Salisbury, Claudio Melchiorri
Venue: Proceedings of the First Joint Eurohaptics Conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems (2005)

Rendering stiff virtual objects remains a core challenge in the field of haptics. A study of this problem is presented, which relates the maximum achievable object stiffness to the elements of the control loop. In particular, we examine how the sampling rate and quantization of position measurements interact with the inertia, natural viscous, and Coulomb damping of the haptic device. The resulting stability criterion generalizes previously known conditions. Simulations and experimental results support the theoretical analysis based on the passivity and describing function approaches.
User experiences on combining location sensitive mobile phone applications and multimedia messaging
Authors: Jonna Häkkilä, Jani Mäntyjärvi
Venue: Proceedings of the 3rd international conference on Mobile and ubiquitous multimedia (2004)

Quickly emerging usage of multimedia messages offers new approach for mobile and collaboration between users and services by providing a mature and easy accessible technology. This paper investigated possibilities of location related messaging, where pictorial and textual information are combined. We present a model involving contextual information delivery for a mobile user, and evaluate it by user tests with location sensitive multimedia messaging representing different application categories. The results show that the functionality and social acceptance varies between different message categories. It is suggested that distinct information elements should employ sharing and access right management, and a commonly agreed categorization system is required for successful information filtering.

Zone-Based Routing Algorithm for Congestion Control over the Internet
Authors: Ashraf Uddin Ahmed, Senro Saito, Zixue Cheng
Venue: Proceedings of the 19th International Conference on Advanced Information Networking and Applications - Volume 1 (2005)

With the rapid growth of information technology over the past few years severe congestion problems have resulted. Many existing models have been proposed to control the congestion for a single network device (router, link etc.). The main problem is when the link or the router between the source and destination is with high congestion or broken down, etc. If there are no alternate links to the destination, users have to wait for the mechanical solutions for the recovery, which will take long time and is expensive as the congestion is at a micro-level. Therefore, we propose a zone-based, congestion control algorithm which is easy to implement and users do not have to wait for when the link or router is congested or broken down. The Zone-based routing algorithm is proposed to route the traffic and balance the traffic load to achieve efficient resource utilization. Zone is equal to one AS (Autonomous Systems) or a collection of neighboring ASes.
Online Detection and Diagnosis of Multiple Configuration Upsets in LUTs of SRAM-Based FPGAs
Authors: E. Syam Sundar Reddy, Vikram Chandrasekhar, M. Sashikanth, V. Kamakoti, N. Vijaykrishnan
Venue: Proceedings of the 19th IEEE International Parallel and Distributed Processing Symposium (IPDPS'05) - Workshop 3 - Volume 04 (2005)

This paper proposes a new CLB architecture for FPGAs and associated online testing and reconfiguration techniques that detect configuration upsets in the LUTs of SRAMbased FPGAs and correct them using partial reconfiguration. These configuration upsets may either be Single Event Upsets(SEUs) or even Multiple Configuration Upsets. Any error in a CLB is detected with a latency of just 16 clock cycles and the erros are diagnosed by propagating them to a single output port by a chain-like shift register.The proposed CLB architectures requires only 2 additional SRAM configuration bits per LUT for a Xilinx Virtex II architecture. This is extremely low when compared to the 16 additional SRAM configuration bits required by CLB architectures used to implement standard DWC techniques for detecting configuration upsets in LUTs.
An effective recommender system for highly dynamic and large web sites
Authors: Ranieri Baraglia, Francesco Merlo, Fabrizio Silvestri
Venue: Proceedings of the 8th European Conference on Principles and Practice of Knowledge Discovery in Databases (2004)

In this demo we show a recommender system, called SUGGEST, that dynamically generates links to pages that have not yet been visited by a user and might be of his potential interest. Usually other recommender systems exploit a kind of two-phase architecture composed by an off-line component that analyzes Web server access logs and generates information used by a successive online component that generates recommendations. SUGGEST collapse the two-phase into a single online Apache module. The component is able to manage very large Web sites made up of dinamically generated pages by means of an efficient LRU-based database management strategy. The demo will show the way SUGGEST is able to anticipate users requests that will be made farther in the future, introducing a limited overhead on the Web server activity.
Interacting with robots: can we encourage social interaction skills in children with autism?
Authors: Ben Robins, Kerstin Dautenhahn
Venue: Issue 80 (September 2004) (2004)

Robots, virtual environments and other computer based technologies are increasingly applied in therapy and education. The work reported in this article, being part of the Aurora project [1], investigates the potential use of robots as therapeutic or educational 'toys' specifically for use by children with autism. Children with autism show difficulties in social interaction, communication and imagination (referred to by many authors as the triad of impairment, e.g. [15]). Our research focuses on ways that robotic systems can engage autistic children in simple interactive activities (e.g. imitation and turn--taking games) with the aim of encouraging basic communication and social interaction skills.
