Authors: Jose M. Torres, Jose M. Sarriegi, Josune Hernantes, Ana Lauge
Venue: Proceedings of the 6th International Conference on Trust, Privacy and Security in Digital Business (2009)

This paper presents the results of a security management survey of IT administrators from small and medium sized enterprises (SMEs) who ranked predefined Critical Success Factors (CSFs) and Indicators. The outcome of this study relies on the development of a set of security management guidelines that allows IT administrators to adopt assessment and managerial security routines. The secondary contribution relies on allowing IT administrators to establish a culture of implementing and tracking the effectiveness of technical and non-technical security controls. The survey results describe how IT administrators would like the most critical aspects of security to evolve.
Energy Shaping Repetitive Control Technology for Shunt Active Power Filter
Authors: Liang Zhishan, Xie Zhengxian, Liu Qingsheng, Wei Xueliang, Zhang Huaguang
Venue: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 03 (2009)

Active Power Filter (APF) is usually used to compensate the harmonic currents which are generated by the nonlinear load, and its compensation performance mainly depends on the estimation of APF mathematic model, instruction signal of harmonic currents and design of controller. Traditional control APF uses the average mathematic model, and PI controller and its instruction signal of harmonic currents is obtained by load harmonic currents. This paper adopts the energy shaping repetitive control technology to correct the output current waveform of three-phase three-wire shunt active power filter, Energy Shaping Control can guarantee APF system dynamic stability. Hamiltonian model of APF is built. Instruction signal of harmonic currents is obtained by PI controller of the voltage harmonic where APF is located, in this way, load harmonic currents are not necessary in the control process. The controller design procedure is analyzed in detail. Theoretical analysis and experimental results demonstrate the validity of the proposed method, the filtering performance is improved obviously.

Authors: Chandani Anand, Shashikant Sadistap, Satish Bindal, K. S. N. Rao
Venue: Proceedings of the 2009 Third International Conference on Sensor Technologies and Applications (2009)

The paper presents a development of the multi sensor embedded system for measuring up to eight sensor parameters optimized by appropriate algorithms. Since most of the industrial applications use the analog sensors with transmitters for sensing the process parameters particularly in harsh environment because of their strong mechanical packaging and ruggedness. Then the benefits of digital technology in the vast world of analog sensors can be implemented by development of appropriate multi sensor embedded system. The developed system has most of the features of smart sensing and communicating to other embedded/Host PC through a wireless interface. The developed prototype system has been tested with RTD temperature sensors for temperature measurement over a wireless connectivity for various distances. Further, the average loss in signal is measured and received power is calculated and compared. Finally, the effect of obstacles at indoor and outdoor range on wireless transmission has been presented. It is observed that for better transmission of signals via wireless communication, the low frequency along with low baud rate and line of sight range is required to minimize the signal loss.
Pronunciation modeling in spelling correction for writers of English as a foreign language
Authors: Adriane Boyd
Venue: Proceedings of Human Language Technologies: The 2009 Annual Conference of the North American Chapter of the Association for Computational Linguistics, Companion Volume: Student Research Workshop and Doctoral Consortium (2009)

We propose a method for modeling pronunciation variation in the context of spell checking for non-native writers of English. Spell checkers, typically developed for native speakers, fail to address many of the types of spelling errors peculiar to non-native speakers, especially those errors influenced by differences in phonology. Our model of pronunciation variation is used to extend a pronouncing dictionary for use in the spelling correction algorithm developed by Toutanova and Moore (2002), which includes models for both orthography and pronunciation. The pronunciation variation modeling is shown to improve performance for misspellings produced by Japanese writers of English.
Ubiquitous city: Urban technologies, urban infrastructure and urban informatics
Authors: Dong-Hee Shin
Venue: Journal of Information Science (2009)

South Korea continues to lead the way in digital opportunity with its recent, innovative and ubiquitous city projects. The u-city initiative in South Korea is a national urban development project that focuses on strengthening the role of information and communication technologies in civic planning and management. This study tracks the changing dynamics driving the information society initiative of South Korea to evaluate the process of design and development of u-city. This study reviews qualitative data related to the u-city projects, describes the transformations and translation of this data in the public, political, and social discourse, and discusses the prospectus of a ubiquitous information society environment. The findings raise fundamental, practical questions about the role of ubiquitous computing in shaping our future cities. The findings show that there are more challenges ahead than prospects, despite the fact that the u-city has all the advanced technological components for a positive development. The South Korean u-city is typically more prone to problems related to the lack of social infrastructure, market restrictions, political quagmires and vested financial interests. The paper discusses the deficiencies of the South Korean approach, namely a lack of holistic approach by integrating technological possibilities with social application needs.
Research on Fogdrop Diameter Based on Neural Network
Authors: Rui Li, Ziming Kou
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

ecause of the importance of dust abatement by sprayer, this paper studies the characteristic of fogdrop generated by one kind of nozzle on basis of Back Propagation (BP) Neural Network, using Marvin-3000 type laser granularity instrument in lab. It is pointed that the maximum and minimum errors of widely used BP Neural Network are 2.18% and 0.61%, when we compute the fogdrop diameter computing repeatedly. In more general case, if the nozzle diameter change, the maximum and minimum errors using BP Neural Network are 1.92% and 0.34% by comparing with other’s work, while the errors are 2.13% and 1.50% when pressure change. The experimental results show that BP neural network is an effective tool to predict the variation of the non-linear fogdrop diameter. Furthermore, it is potential to be used in other kinds of fogdrop and real industry application.
Characterization of Creep Properties of Zeolite Molecular Sieves Using Nanoindentation Test
Authors: Tong Chen, Yong Ma, Xiaoyan Niu, Xuefeng Shu, Jianwen Zhang
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

The creep behavior of Zeolite molecular sieves has been investigated in this research by using a nanoindentation test. In the holding time, creep curves were obtained. The results show that the penetration depth during constant load phase is time-dependent. After analysis, creep stress exponents of Zeolite molecular sieves were determined from In vs .InH curves. Given a secondary creep material model, the indention processes of Zeolite molecular sieves were simulated with the ANSYS finite element code by force loading. The simulative results were consistent with experimental creep curves through modulating the constant C of creep constitutive equation. Therefore, the creep constitutive equations of Zeolite molecular sieves were determined.
Modelling and performance maximization of an integrated automated guided vehicle system using coloured Petri net and response surface methods
Authors: Tauseef Aized
Venue: Computers and Industrial Engineering (2009)

The objective of this study is to model and maximize performance of an integrated Automated Guided Vehicle System (AGVS), which is embedded in a pull type multi-product, multi-stage and multi-line flexible manufacturing system (FMS). This study examines the impact of guide-path flexibility on system performance through the development of three different guide-path configurations which range from dedicated to flexible relationships between automated guided vehicles (AGVs) and machine/assembly station resources. The system is modelled using coloured Petri net method (CPN) and the simulation results lead to identify the resource redundancy which can be rectified to achieve lower overall cost of the system through the development of flexible guide-path configurations. The study is extended to seek global near-optimal conditions for each guide-path configuration using response surface method, which yields improvements in system throughput and cycle time along with a decrease in the numbers of AGVs.
Complexity of finding the BLEU-optimal hypothesis in a confusion network
Authors: Gregor Leusch, Evgeny Matusov, Hermann Ney
Venue: Proceedings of the Conference on Empirical Methods in Natural Language Processing (2008)

Confusion networks are a simple representation of multiple speech recognition or translation hypotheses in a machine translation system. A typical operation on a confusion network is to find the path which minimizes or maximizes a certain evaluation metric. In this article, we show that this problem is generally NP-hard for the popular BLEU metric, as well as for smaller variants of BLEU. This also holds for more complex representations like generic word graphs. In addition, we give an efficient polynomial-time algorithm to calculate unigram BLEU on confusion networks, but show that even small generalizations of this data structure render the problem to be NP-hard again. Since finding the optimal solution is thus not always feasible, we introduce an approximating algorithm based on a multi-stack decoder, which finds a (not necessarily optimal) solution for n-gram BLEU in polynomial time.
Users Can Do Better with PDAs Than Paper: A Usability Study of PDA-Based vs. Paper-Based Nursing Documentation Systems
Authors: Néstor J. Rodríguez, José A. Borges, Gilberto Crespo, Carlos Pérez, Carlos Martinez, Celia R. Colón-Rivera, Aixa Ardín
Venue: Proceedings of the 5th International Conference on Universal Access in Human-Computer Interaction. Part III: Applications and Services (2009)

Personal Digital Assistants (PDAs) are a viable technology for providing access to Electronic Medical Records at the point-of-care. However, acceptance of this technology by clinicians will depend on how easy they can make the transition from the system they normally use to a PDA-based system. Since many hospitals are still using paper-based patient record systems this study intends to provide some insight on the aspects that need to be considered in the transition from a paper-based system to a PDA-based system. The study compares the interaction of nurses with PDA-based and paper-based nursing documentation systems in terms of performance and subjective satisfaction. Twenty staff nurses from a metropolitan hospital performed twelve tasks on each system. The study supports the conclusion that a PDA-based nursing documentation system can be superior to a paper-based system in term of performance for tasks that don't required writing notes. Nurses were significantly more satisfied with the PDA-based system than with the paper-based system with every interaction and system aspect evaluated on the study. In general the results of the study provide hard evidence to predict an easy transition for nurses from a paper-based system to a PDA-based system nursing documentation system.
The "False Colour" Problem
Authors: Jean Serra
Venue: Proceedings of the 9th International Symposium on Mathematical Morphology and Its Application to Signal and Image Processing (2009)

The emergence of new data in multidimensional function lattices is studied. A typical example is the apparition of false colours when (R,G,B) images are processed. Two lattice models are specially analysed. Firstly, one considers a mixture of total and marginal orderings where the variations of some components are governed by other ones. This constraint yields the "pilot lattices". The second model is a cylindrical polar representation in n dimensions. In this model, data that are distributed on the unit sphere of n ¿ 1 dimensions need to be ordered. The proposed orders, and lattices are specific to each image. They are obtained from Voronoi tesselation of the unit sphere The case of four dimensions is treated in detail and illustrated.
A framework for distributed knowledge management: Design and implementation
Authors: Giuseppe Pirró, Carlo Mastroianni, Domenico Talia
Venue: Future Generation Computer Systems (2010)

This paper describes a framework for implementing distributed ontology-based knowledge management systems (DOKMS). The framework, in particular, focuses on knowledge management within organizations. It investigates the functional requirements to enable Individual Knowledge Workers (IKWs) and distributed communities (e.g., project teams) to create, manage and share knowledge with the support of ontologies. On the one hand, the framework enables distributed and collaborative work by relying on a P2P virtual office model. On the other hand, it provides a multi-layer ontology framework to enable semantics-driven knowledge processing. The ontology framework allows organizational knowledge to be modeled at different levels. An Upper Ontology is exploited to establish a common organizational knowledge background. A set of Workspace Ontologies can be designed to manage, share and search knowledge within communities by the establishment of a contextual (i.e., related to the aim of a group) understanding. Finally, Personal Ontologies support IKWs in personal knowledge management activities. We present an implementation of the designed framework in the K-link+ system and show the suitability of this approach through a use case. The evaluation of K-link+ in a real network is also discussed.
Mechanism of Pb(II) Biosorption by Saccharomyces Cerevisiae
Authors: Dong Limin, Du Juan, Bai Xin, Yu Naili, Fan Chunhui, Zhang Ying
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 01 (2009)

The mechanism of Pb (II) biosorption by Saccharmyces Cerevisiae is investigated by scanning electron microscopy-energy dispersive x-ray (SEM-EDX) sepectroscopy,fourier transform infrared (FTIR) spectroscopy and x-ray photoelectron spectroscopy (XPS).The SEM figures show that the shapes of Saccharomyces Cerevisiae cells doesn’t obviously change after the adsorption,but there are many “spots” on the cell walls,which indicates the cell walls of Saccharomyces Cerevisiae play an important role in adsorption process.The EDX spectrum analysis helps to substantiate the interactive adsorption between Pb (Ⅱ) and K (Ⅰ)on the cell surfaces. FTIR analysis indicates that COOH, C=O, C-O and N-H are the main active binding sites for the process of adsorption. XPS analysis further reveals that Pb (Ⅱ) combines with some active functional groups containing the elements of C, N, O and P. Therefore, the mechanism of saccharomyces cerevisiae adsorption on Pb(Ⅱ) has mainly resulted from both the ion exchange and the surface complexation.

Authors: Jumat Sulaiman, Mohamed Othman, Mohammad Khatim Hasan
Venue: Proceedings of the International Conference on Computational Science and Its Applications: Part I (2009)

In previous studies, the 4 Point-Explicit Decoupled Group (EDG) iterative method without or with a weighted parameter, ¿ has been shown to be much faster as compared to the existing four point block iterative method. Due to the effectiveness of this method, the primary goal of this paper is to illustrate the advantage of the 9 Point-EDGSOR in solving two-dimensional Poisson equations by using the half-sweep triangle finite element approximation equation based on the Galerkin scheme. In fact, formulations of the 4, 6, and 9 Point-EDGSOR iterative methods are also presented. Results of numerical experiments are recorded to show the effectiveness of the 9 Point-EDGSOR method as compared to the 4, and 6 Point-EDGSOR methods.

Authors: Tor-Morten Grønli, Gheorghita Ghinea
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part III: Ubiquitous and Intelligent Interaction (2009)

Personal Information Managers exploit the ubiquitous paradigm in mobile computing technology to integrate services and programs for business and leisure. Recognizing that every situation is constituted by information and events, this context will vary depending on the situation users are in, and the tasks they are about to commit. The value of context as a source of information is highly recognized and for individual dimensions context has been both conceptually described and prototypes implemented. The novelty in this paper is a new implementation of context by integrating three dimensions of context: social information, activity information and geographical position. Based on an application developed for Microsoft Window Mobile these three dimensions of context are explored and implemented in an application for mobile telephone users. Experiment conducted show the viability of tailoring contextual information in three dimensions to provide user with timely and relevant information.
Using multiresolution learning for transfer in image classification
Authors: Eric Eaton, Marie DesJardins, John Stevenson
Venue: Proceedings of the 22nd national conference on Artificial intelligence - Volume 2 (2007)

Our work explores the transfer of knowledge at multiple levels of abstraction to improve learning. By exploiting the similarities between objects at various levels of detail, multiresolution learning can facilitate transfer between image classification tasks. We extract features from images at multiple levels of resolution, then use these features to create models at different resolutions. Upon receiving a new task, the closest-matching stored model can be generalized (adapted to the appropriate resolution) and transferred to the new task.

Frequency matters: pitch accents and information status
Authors: Katrin Schweitzer, Michael Walsh, Bernd Möbius, Arndt Riester, Antje Schweitzer, Hinrich Schütze
Venue: Proceedings of the 12th Conference of the European Chapter of the Association for Computational Linguistics (2009)

This paper presents the results of a series of experiments which examine the impact of two information status categories (given and new) and frequency of occurrence on pitch accent realisations. More specifically the experiments explore within-type similarity of pitch accent productions and the effect information status and frequency of occurrence have on these productions. The results indicate a significant influence of both pitch accent type and information status category on the degree of within-type variability, in line with exemplartheoretic expectations.
A decomposed theory of reasoned action to explain intention to use Internet stock trading among Malaysian investors
Authors: T. Ramayah, Kamel Rouibah, M. Gopi, Gary John Rangel
Venue: Computers in Human Behavior (2009)

This article studied factors influencing the intention to use Internet stock trading among investors in Malaysia. To achieve this objective, this study selected the decomposed theory of reasoned action as a theoretical basis to explain variation in intention to use. Structured questionnaires were used to collect data from 144 current and potential investors who are aware of Internet stock trading in Malayisa. Findings show that attitude and subjective norm have a direct positive relationship towards behavioral intention to use Internet stock trading. Attitude was significantly influenced by perceived ease of use and perceived usefulness whereas subjective norm was significantly influenced by injunctive norm and descriptive norm which were proposed as antecedents. In addition the results of the study could serve as a guideline for online stock broking organizations in understanding the factors and programs that need to be initiated to increase online stock trading among current and potential retail investors. As not much has been written on decomposed theory of reasoned action, particularly in Internet stock trading, this study adds to the literature of understanding intention to use a technology in a developing country.
