Gap Analysis Methodology for Business Service Engineering
Authors: Dinh Khoa Nguyen, Willem-Jan van den Heuvel, Mike P. Papazoglou, Valeria de Castro, Esperanza Marcos
Venue: Proceedings of the 2009 IEEE Conference on Commerce and Enterprise Computing (2009)

Many of today’s service analysis and design techniques rely on ad-hoc and experience-based identification of value-creating business services and implicitly assume a “green-field” situation focusing on the development of completely new services while offering very limited support for discovering candidate services from pre-existing software assets. In this article, we introduce a novel business service engineering methodology that identifies and conceptualizes business services in a business domain. Our approach takes into account a realistic scenario, in which pre-existing enterprise assets are considered for the reuse to implement fragments of the newly conceived business services.
A Multiple Scanning Strategy for Entropy Based Discretization
Authors: Jerzy W. Grzymala-Busse
Venue: Proceedings of the 18th International Symposium on Foundations of Intelligent Systems (2009)

We present results of experiments performed on 14 data sets with numerical attributes using a novel technique of discretization called multiple scanning. Multiple scanning is based on scanning all attributes of the data set many times, during each scan the best cut-points are found for all attributes. Results of our experiments show that multiple scanning enhances successfully, in terms of the error rate, an ordinary discretization technique based on conditional entropy.
A quorum-based framework for establishing control channels in dynamic spectrum access networks
Authors: Kaigui Bian, Jung-Min Park, Ruiliang Chen
Venue: Proceedings of the 15th annual international conference on Mobile computing and networking (2009)

Establishing a control channel for medium access control is a challenging problem in multi-channel and dynamic spectrum access (DSA) networks. In the design of multi-channel MAC protocols, the use of channel (or frequency) hopping techniques (a.k.a. parallel rendezvous) have been proposed to avoid the bottleneck of a single control channel. In DSA networks, the dynamic and opportunistic use of the available spectrum requires that the radios are able to "rendezvous" -- i.e., find each other to establish a link. The use of a dedicated global control channel simplifies the rendezvous process but may not be feasible in many opportunistic spectrum sharing scenarios due to the dynamically changing availability of all the channels, including the control channel. To address this problem, researchers have proposed the use of channel hopping protocols for enabling rendezvous in DSA networks. This paper presents a systematic approach, based on quorum systems, for designing and analyzing channel hopping protocols for the purpose of control channel establishment. The proposed approach, called Quorum-based Channel Hopping (QCH) system, can be used for implementing rendezvous protocols in DSA networks that are robust against link breakage caused by the appearance of incumbent user signals. We describe two optimal QCH systems under the assumption of global clock synchronization: the first system is optimal in the sense that it minimizes the time-to-rendezvous between any two channel hopping sequences; the second system is optimal in the sense that it guarantees the even distribution of the rendezvous points in terms of both time and channel, thus solving the \emph{rendezvous convergence} problem. We also propose an asynchronous QCH system that does not require global clock synchronization. Our analytical and simulation results show that the channel hopping schemes designed using our framework outperform existing schemes under various network conditions.

Authors: Ming-Ying Yang, Manlai You, Ya-Lin Tu, Yung-Ping Chou
Venue: Proceedings of the 3rd International Conference on Internationalization, Design and Global Development: Held as Part of HCI International 2009 (2009)

This study aims to propose a model of Industrial Design Career Information System (IDCIS) to help ID students plan their career. The study was divided into three stages. The content analysis of nine relevant websites framed a basic structure of IDCIS. Next, four focus groups with a total of twenty-four ID students were interviewed to find out what career information they would like to know. Finally, a web-based model of IDCIS was simulated and eight ID students were invited to provide their feedback. The outcome would provide an integrated base to help students be aware of the ID profession and plan their career in advance during the school years. Also, the process of constructing a model of IDCIS adopted by this study could be a reference for other fields.

Authors: Suleman Shahid, Omar Mubin, Abdullah Al Mahmud
Venue: Proceedings of the 5th International Conference on Universal Access in Human-Computer Interaction. Addressing Diversity. Part I: Held as Part of HCI International 2009 (2009)

This paper explores the usability requirements of a navigation system for older adults by identifying the key usability and ergonomic problems in existing navigation systems and proposing a set of new guidelines for designing such systems. We also discuss the design of a new Route Assisting and Communication system for Elderly (RACE) in which design guidelines are incorporated. Our results are primarily obtained from a series of usability evaluations undertaken with the elderly. This paper also identifies a number of advance features that a routing system should have for satisfying older adults on road. We suggest design implications for navigation systems based on our research and lay the path for future work.

Algebraic Attacks on RFID Protocols
Authors: Ton Deursen, Saša Radomirović
Venue: Proceedings of the 3rd IFIP WG 11.2 International Workshop on Information Security Theory and Practice. Smart Devices, Pervasive Systems, and Ubiquitous Networks (2009)

This work aims to identify the algebraic problems which enable many attacks on RFID protocols. Toward this goal, three emerging types of attacks on RFID protocols, concerning authentication, untraceability, and secrecy are discussed. We demonstrate the types of attacks by exhibiting previously unpublished vulnerabilities in several protocols and referring to various other flawed protocols.The common theme in these attacks is the fact that the algebraic properties of operators employed by the protocols are abused. While the methodology is applicable to any operator with algebraic properties, the protocols considered in this paper make use of xor, modular addition, and elliptic curve point addition.

Authors: Lin Xiaoying, Su Xianbo
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 02 (2009)

The exploration and development of coalbed methane (CBM) is favorable not only to the complementarity of conventional natural gas, but to the reduction of gas disaster. At the meanwhile, it brings a series of problems of ecological environment because of unsuitable exploitation activity. The main ecological environment problems are systematically discussed in this paper based on the effects of the development of CBM on water resource, on atmosphere, on vegetation, on infield, and on habitation. Some corresponding environmental protection countermeasures are put forward. Before the exploration and development of CBM, the effect on environment should be appraised, and the development field of CBM should be availably layout. During the process of the exploration and development of CBM, supervision should be strengthened and the environmental protection measures should be put into effect. After the completion of CBM well, land reclamation should be put up in time that is propitious to the environmental protection of developed field.
Evaluating the Effect of Local Variations in Visually-Similar Motions on the Clustering of Body Sensor Features
Authors: Gaurav N. Pradhan, B. Prabhakaran
Venue: Proceedings of the 2009 Sixth International Workshop on Wearable and Implantable Body Sensor Networks (2009)

Body Sensor Network-related applications such as assistive-living environment, orthopedic, physical medicines, and rehabilitation use wearable body sensors like motion trackers to track joint movements and electromyogram sensors to track muscular activities. These sensors provide information in the form of multidimensional time series data. Generally, for these applications, classification or similarity retrieval of human motions is performed by traditional clustering of dimensionally-reduced feature vectors based on joint movements and/or muscular activities. However, local variations in visually-similar sets of human motions cause them to group in different clusters resulting to a lower recall during retrieval. Hence, it is important to evaluate the effect of local variations on the given clustering of feature vectors. In this paper, we represent the local variations in the form of quantitative attributes that are measured from sensors' time series data. And further, we propose a multivariate analysis of variance technique for evaluating the effect of quantitative attributes on the clustering results that are based on different configurations of feature vectors representing joint movements and muscular activities.
Dynamic Load Balancing for Cluster-Based Publish/Subscribe System
Authors: Hojjat Jafarpour, Sharad Mehrotra, Nalini Venkatasubramanian
Venue: Proceedings of the 2009 Ninth Annual International Symposium on Applications and the Internet (2009)

In this paper we present load balancing techniques for Cluster-based pub/sub framework that include both static and dynamic load balancing. The static load balancing is done through a multi-cluster architecture for broker overlay network which is based on subscription distribution knowledge in the event space. The dynamic load balancing,on the other hand, is achieved through exploiting multiple inter-cluster and intra-cluster connections to dynamically distribute publication and subscription forwarding load among brokers during run time. Our experimental results show that the proposed load balancing techniques effectively prevent overloaded brokers without having significant effect on content dissemination efficiency.
Automatic Line Orientation Measurement for Questioned Document Examination
Authors: Joost Beusekom, Faisal Shafait, Thomas Breuel
Venue: Proceedings of the 3rd International Workshop on Computational Forensics (2009)

In questioned document examination many different problems arise: documents can be forged or altered, signatures can be counterfeited, etc. When experts attempt to identify such forgeries manually, they use among others line orientation as a feature. This paper describes an automatic mean for measuring the line justification and helping the specialist to find suspicious lines. The goal is to use this method as one of several screening tools for scanning large document collections for the potential presence of forgeries. This method extracts the text-lines, measures their orientation angle and decides the validity of these measured angles based on previously trained parameters.

A mathematical programming formulation for sparse collaborative computer aided diagnosis
Authors: Jinbo Bi, Tao Xiong
Venue: Proceedings of the 22nd national conference on Artificial intelligence - Volume 1 (2007)

A mathematical programming formulation is proposed to eliminate irrelevant and redundant features for collaborative computer aided diagnosis which requires to detect multiple clinically-related malignant structures from medical images. A probabilistic interpretation is described to justify our formulations. The proposed formulation is optimized through an effective alternating optimization algorithm that is easy to implement and relatively fast to solve. This collaborative prediction approach has been implemented and validated on the automatic detection of solid lung nodules by jointly detecting ground glass opacities.

Theia is a software framework for multispectral image analysis. The design is grounded on the object-oriented approach and a model combining parallel computation with selective data processing. Multispectral images from the archaeological site of Aquileia, Italy, have been used as the experimental testbed in order to assess the effectiveness and performance of the system; satisfactory results are reported, and are quite promising towards the use of the framework as a dynamic, interactive interface to real-time data exploration and processing.
Omiotis: A Thesaurus-Based Measure of Text Relatedness
Authors: George Tsatsaronis, Iraklis Varlamis, Michalis Vazirgiannis, Kjetil Nørvåg
Venue: Proceedings of the European Conference on Machine Learning and Knowledge Discovery in Databases: Part II (2009)

In this paper we present a new approach for measuring the relatedness between text segments, based on implicit semantic links between their words, as offered by a word thesaurus, namely WordNet. The approach does not require any type of training, since it exploits only WordNet to devise the implicit semantic links between text words. The paper presents a prototype on-line demo of the measure, that can provide word-to-word relatedness values, even for words of different part of speech. In addition the demo allows for the computation of relatedness between text segments.
Querying XML Data with SPARQL
Authors: Nikos Bikakis, Nektarios Gioldasis, Chrisa Tsinaraki, Stavros Christodoulakis
Venue: Proceedings of the 20th International Conference on Database and Expert Systems Applications (2009)

SPARQL is today the standard access language for Semantic Web data. In the recent years XML databases have also acquired industrial importance due to the widespread applicability of XML in the Web. In this paper we present a framework that bridges the heterogeneity gap and creates an interoperable environment where SPARQL queries are used to access XML databases. Our approach assumes that fairly generic mappings between ontology constructs and XML Schema constructs have been automatically derived or manually specified. The mappings are used to automatically translate SPARQL queries to semantically equivalent XQuery queries which are used to access the XML databases. We present the algorithms and the implementation of SPARQL2XQuery framework, which is used for answering SPARQL queries over XML databases.
SISR --- A New Model for Epidemic Spreading of Electronic Threats
Authors: Boris Rozenberg, Ehud Gudes, Yuval Elovici
Venue: Proceedings of the 12th International Conference on Information Security (2009)

Epidemic spreading in complex networks has received much attention in recent years. Previous research identified a propagation scenario of electronic threats which has not been described by any of the existing analytical models. In this scenario an infected node instead of being removed contributes to the infection spreading upon the reinfection attempt (for example, Sober, Sobig, and Mydoom Worms). In this paper we formally define and describe analytically a new model, Susceptible-Infected-Suspended-Reinfected (SISR), which complies with this scenario of epidemic spreading in both homogeneous and complex networks. We then evaluate the model by comparing it to the SIR model and by comparing its estimations with simulation results.
Semi-supervised Text Classification Using RBF Networks
Authors: Eric P. Jiang
Venue: Proceedings of the 8th International Symposium on Intelligent Data Analysis: Advances in Intelligent Data Analysis VIII (2009)

Semi-supervised text classification has numerous applications and is particularly applicable to the problems where large quantities of unlabeled data are readily available while only a small number of labeled training samples are accessible. The paper proposes a semi-supervised classifier that integrates a clustering based Expectation Maximization (EM) algorithm into radial basis function (RBF) neural networks and can learn for classification from a very small number of labeled training samples and a large pool of unlabeled data effectively. A generalized centroid clustering algorithm is also investigated in this work to balance predictive values between labeled and unlabeled training data and to improve classification accuracy. Experimental results with three popular text classification corpora show that the proper use of additional unlabeled data in this semi-supervised approach can reduce classification errors by up to 26%.

Authors: A. A. Uspenskii, P. D. Lebedev
Venue: Automation and Remote Control (2009)

The set of the symmetry is introduced into consideration, allowing to construct the optimal outcome function for one class of time-optimal problems. Formulas for a finding of this set on a plane are offered. The results find application at studying of geometry of nonconvex sets, in the theory of optimal control and in the theory of positional differential games at studying nonsmooth features of sets of attainability, stable bridges. Besides results can be useful to experts on the equations of Hamilton-Jacobi types, working within the limits of various concepts of the generalized solutions of these equations.
