Research on the Improvement of Reinforcement Learning Using Neural Networks
Authors: Xuejun Yang, Hong Wang
Venue: Proceedings of the 2009 Asia-Pacific Conference on Information Processing - Volume 01 (2009)

The cyber informatics approach to agents is defined not only by the analysis of 802.11b, but also by the technical need for red-black trees. In fact, few experts would disagree with the understanding of cache coherence, which embodies the practical principles of complexity theory. In this work, we explore an application for omniscient methodologies, which we use to verify that neural networks and operating systems can collude to achieve this mission.
An LMI Approach to Stochastic Stability Analysis for Uncertain Discrete-Time Markovian Jump Singular System with State-Delay
Authors: Zhiming Zhou, Hongqian Lu
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

This paper considers the stochastic stability analysis of uncertain discrete-time singular system with Markovian jumping parameters and state delay. The considered systems are not necessarily assumed to be regular and causal. In term of linear matrix inequality approach, a delay-dependent robust admissibility condition is given to ensure the system to be stochastically admissible. Finally, an example is provided to demonstrate the effectiveness of the proposed approach.
Haptic Navigation in the World Wide Web
Authors: Nikolaos Kaklanis, Dimitrios Tzovaras, Konstantinos Moustakas
Venue: Proceedings of the 5th International Conference on Universal Access in Human-Computer Interaction. Part III: Applications and Services (2009)

This paper presents a methodology for mapping a web page onto a 3D virtual reality environment enriched with haptic feedback and an application that has been developed according to the proposed methodology and gives blind people the opportunity to navigate through the internet by touch. According to the proposed haptic navigation in the world wide web, haptic and virtual modalities are combined together in order to enhance user experiences for multiple users: a normal sighted person is able to interact with the virtual reality scene via the visual or/and the auditory or/and the haptic information channel, a blind person is able to interact with the virtual reality scene by hearing and touch, a person having a small visual impairment benefits from the haptic feedback to reinforce the visual channel. The haptic navigation overcomes some of the shortcomings posed by audio rendering of web pages, such as the sequential navigation.

Authors: Weidong Qiu, Jie Guo, Zheng Gong, Zheng Huang
Venue: Proceedings of the 2009 Second International Symposium on Electronic Commerce and Security - Volume 01 (2009)

Many privacy-protecting electronic payment systems have been proposed to realize the revocable anonymity among users. In this paper, by organizing all users into a group, we present an anonymity revocable electronic prosecution report system. The report system is efficient and the user’s privacy will not be compromised in normal cases. However, when defamation was detected, the anonymity can be removed by electronic report centerwith the help of an off-line trusted third party(TTP). The proposed system is practical and can be applied to military or government as an internal prosecution report system which is also defamation resistant.
Exploring Agility in Distributed Information Systems Development Teams: An Interpretive Study in an Offshoring Context
Authors: Saonee Sarker, Suprateek Sarker
Venue: Information Systems Research (2009)

Agility is increasingly being seen as an essential element underlying the effectiveness of globally distributed information systems development (ISD) teams today. However, for a variety of reasons, such teams are often unable develop and enact agility in dealing with changing situations. This paper seeks to provide a deeper understanding of agility through an intensive study of the distributed ISD experience in TECHCOM, an organization widely recognized for its excellence in IT development and use. The study reveals that agility should be viewed as a multifaceted concept having three dimensions: resource, process, and linkage. Resource agility is based on the distributed development team's access to necessary human and technological resources. Process agility pertains to the agility that originates in the team's systems development method guiding the project, its environmental scanning, and sense-making routines to anticipate possible crises, and its work practices enabling collaboration across time zones. Linkage agility arises from the nature of interactional relationships within the distributed team and with relevant project stakeholders, and is composed of cultural and communicative elements. The paper highlights some of the difficulties in developing agility in distributed ISD settings, provides actionable tactics, and suggests contingencies wherein different facets of agility may become more (or less) critical.
Tagging Portuguese with a Spanish tagger using cognates
Authors: Jirka Hana, Anna Feldman, Chris Brew, Luiz Amaral
Venue: Proceedings of the International Workshop on Cross-Language Knowledge Induction (2006)

We describe a knowledge and resource light system for an automatic morphological analysis and tagging of Brazilian Portuguese. We avoid the use of labor intensive resources; particularly, large annotated corpora and lexicons. Instead, we use (i) an annotated corpus of Peninsular Spanish, a language related to Portuguese, (ii) an unannotated corpus of Portuguese, (iii) a description of Portuguese morphology on the level of a basic grammar book. We extend the similar work that we have done (Hana et al., 2004; Feldman et al., 2006) by proposing an alternative algorithm for cognate transfer that effectively projects the Spanish emission probabilities into Portuguese. Our experiments use minimal new human effort and show 21% error reduction over even emissions on a fine-grained tagset.
Interactive configuration with regular string constraints
Authors: Esben Rune Hansen, Henrik Reif Andersen
Venue: Proceedings of the 22nd national conference on Artificial intelligence - Volume 1 (2007)

In this paper we present a generalization of the problem of interactive configuration. The usual interactive configuration problem is the problem of, given some variables on small finite domains and an increasing set of assignment of values to a subnet of the variables, to compute for each of the unassigned variables which values in its domain that participate in some solution for some assignment of values to the other unassigned variables. In this paper we consider how to extend this scheme to handle infinite regular domains using string variables and constraints that involves regular-expression checks on the string variables. We first show how to do this by using one single DFA. Since this approach is vastly space consuming, we construct a data structure that simulates the large DFA and is much more space efficient. As an example a configuration problem on n string variables with only one solution in which each string variable is assigned a value oflength k the former structure will use Ω(kn) space whereas the latter only need O(kn). We also show how this framework can be combined with the recent BDD techniques to allow both boolean, integer and string variables in the configuration problem.
Multi-level Authentication Scheme Utilizing Smart Cards and Biometrics
Authors: Mücahit Mutlugun, Ibrahim Sogukpinar
Venue: Proceedings of the 2009 Third International Conference on Emerging Security Information, Systems and Technologies (2009)

Authentication is an important part of security area. Smart Cards and Biometrics are widely used in authentication schemes. In this work, we propose a novel architecture and scheme for remote authentication. In this architecture, authentication level is decided by a policy server. The scheme provides an ability to use three authentication factors within different levels. Additional credentials are requested from user upon the authentication level determined by the policy server. The proposed scheme is designed to resist well-known attacks like replay and forgery attacks. At the same time, it fulfills many requirements expected from authentication schemes like mutual authentication and not to keep verification table. We also compared our scheme with well known schemes in the literature.

Under the positive efforts of textile enterprises and the correct guidance of the government, the awareness of sci-tech has greatly improved with a lot progress of sci-tech capability. The effect of sci-tech industrialization gradually emerges. Even some technologies have already been at the forefront of the world. It seems that the whole industry has sound development. This paper analyzed the relation between sci-tech input and economic growth of China’s textile industry from the points of investment, output and contribution ratio, showing the disadvantages in enterprise raising funds, basic research and sci-tech contribution ratio of Chinese textile enterprises, and put forward some countermeasures and proposals.
Multiword lexical acquisition and dictionary formalization
Authors: Cristina Mota, Paula Carvalho, Elisabete Ranchhod
Venue: Proceedings of the Workshop on Enhancing and Using Electronic Dictionaries (2004)

In this paper, we present the current state of development of a large-scale lexicon built at LabEL for Portuguese. We will concentrate on multiword expressions (MWE), particularly on multiword nouns, (i) illustrating their most relevant morphological features, and (ii) pointing out the methods and techniques adopted to generate the inflected forms from lemmas. Moreover, we describe a corpus-based aproach for the acquisition of new multiword nouns, which led to a significant enlargement of the existing lexicon. Evaluation results concerning lexical coverage in the corpus are also discussed.
A comparison of student perceptions regarding online learning versus traditional classroom learning
Authors: Margaret Manella Kozak
Venue: Journal of Computing Sciences in Colleges (2009)

This paper explores a self-assessment of student learning in an online course, versus student learning experience in face-to-face and blended courses. In addition, student self-assessment of an online course experience is compared to that measured for students in the same course, but in blended sections and in a face-to-face section as well. The blended version of the course blends an online component with a face-to-face component and results in approximately half of the course being conducted online and the other half face-to-face in the traditional classroom environment. The purpose of the study was to ascertain whether or not students attending a small university would potentially find the learning experience of online courses to be as worthwhile, rigorous and rewarding as courses offered in the traditional classroom environment. Assessment questions include an evaluation of course assignments, instructor presentation, instructor competence, instructor feedback and approachability, the degree of challenge presented by the course, aptness to recommend the course to others, and enthusiasm for taking additional online courses in the future.
On perturbation theory and an algorithm for maximal clique enumeration in uncertain and noisy graphs
Authors: William Hendrix, Matthew C. Schmidt, Paul Breimyer, Nagiza F. Samatova
Venue: Proceedings of the 1st ACM SIGKDD Workshop on Knowledge Discovery from Uncertain Data (2009)

The maximal clique enumeration (MCE) problem can be used to find very tightly-coupled collections of objects inside a network or graph of relationships. However, when such networks are based on noisy or uncertain data, the solutions to the MCE problem for several closely related graphs may be necessary to accurately define the collections. Thus, we propose an algorithm that efficiently solves the MCE problem on altered, or perturbed, graphs. The algorithm utilizes the enumeration of a baseline graph and identifies only those maximal cliques that the perturbation adds and/or removes. We detail the algorithm and the underlying theory required to guarantee correctness. Further, we report average runtime speedups of 7 and 9 for our algorithm over traditional enumeration techniques in the cases of adding and removing edges, respectively, from graphs constructed from protein interaction data.
Time to Give in: Firm Belief in Administrative Reform as a Driver for Delivering Benefits from IT
Authors: Jeppe Agger Nielsen, Rony Medaglia, Kim Normann Andersen
Venue: Proceedings of the 8th International Conference on Electronic Government (2009)

This paper presents the results of a survey on the opinions of Danish local government managers on the future use of IT after the merger of 271 municipalities into 100. Findings show that the highest expectations on the outcome of IT implementation are related to increased efficiency and to new and better ways to solve tasks. However, the high hopes are contrasted by the respondents' experiences with the use of IT thus far. Managers are not optimistic about the possibility that IT can lead to a strengthening of local democracy and citizen involvement. Overall, findings show that the municipalities' visions on the use of IT support a company-oriented way of thinking that mainly focuses on management and effective operation.
Application Entropy Theory to Detect New Peer-to-Peer Botnet with Multi-chart CUSUM
Authors: Jian Kang, Jun-Yao Zhang
Venue: Proceedings of the 2009 Second International Symposium on Electronic Commerce and Security - Volume 01 (2009)

Botnets have been recognized as one of the most important threats to the security of the Internet. They engage in Distributed Denial of Service (DDOS) attacks, email spamming and other malicious activities likewise. As evolving new features such as decentralized architecture, using P2P networks and etc, new Peer-to-Peer(P2P) botnets could no longer be indicated effectively and accurately by using the traditional detection methods. And we believe that adopting more sophisticated methods from being detected would be the very trend of future botnet development. Thus, in this paper, based on several of the new P2P botnet characteristic properties, we propose a novel detecting method applying the Information Entropy theory in the detection Multi-chart CUSUM. With verification of experiments, it successfully detects the botnet with a relatively high precision.
Reverse k Nearest Neighbor and Reverse Farthest Neighbor Search on Spatial Networks
Authors: Quoc Thai Tran, David Taniar, Maytham Safar
Venue: Transactions on Large-Scale Data- and Knowledge-Centered Systems I (2009)

One of the problems that arise in geographical information systems is finding objects that are influenced by other objects. While most research focuses on kNN (k Nearest Neighbor) and RNN (Reverse Nearest Neighbor) queries, an important type of proximity queries called Reverse Farthest Neighbor (RFN) has not received much attention. Since our previous work shows that kNN and RNN queries in spatial network databases can be efficiently solved using Network Voronoi Diagram (NVD), in this paper, we aim to introduce a new approach to process reverse proximity queries including RFN and RkNN/RkFN queries. Our approach is based on NVD and pre-computation of network distances, and is applicable for spatial road network maps. Being the most fundamental Voronoi-based approach for RFN and RkNN/RkFN queries, our solutions show that they can be efficiently used for networks that have a low and medium level of density.
A Framework and Language Support for Automatic Dynamic Testing of Workflow Management Systems
Authors: Gwan-Hwan Hwang, Che-Sheng Lin, Li-Te Tsao, Kuei-Huan Chen, Yan-You Li
Venue: Proceedings of the 2009 Third IEEE International Symposium on Theoretical Aspects of Software Engineering (2009)

We propose a framework for the automatic dynamic testing of workflow management systems (WfMSs). We first classify faults that can occur during the execution of a WfMS and then describe a systematic testing scheme that provides the following advantages. First, the system developer does not need to play the roles of participants, and hence the entire testing process can be automated. Second, resources that cannot be addressed or represented by the workflow engine can be simulated, which makes the proposed framework also a simulation environment for applications. Third, our platform solves the problems caused by the presence of nondeterministic behavior during dynamic testing of a WfMS. Finally, we describe how to apply temporal logic to verify the dynamic behavior of the tested WfMS. The implementation and experimental results demonstrate the feasibility of the proposed framework.
Reliable Lightpath Routing in Optical Mesh Networks under Multiple Link Failures
Authors: Shengli Yuan
Venue: Proceedings of the 2009 IEEE International Conference on Networking, Architecture, and Storage (2009)

In this work, we study the problem of maximizing lightpath reliability in optical mesh networks against simultaneous failures of multiple fiber links without using protection schemes. The fiber links belong to shared risk link groups (SRLGs) that have arbitrary failure probabilities. This problem is NP-hard and we propose heuristic algorithms for networks with large numbers of SRLGs as well as optimal solutions for networks with smaller numbers of SRLGs. The solutions are evaluated through simulations.
Are You Really Looking? Finding the Answer through Fixation Patterns and EEG
Authors: Anne-Marie Brouwer, Maarten A. Hogervorst, Pawel Herman, Frank Kooi
Venue: Proceedings of the 5th International Conference on Foundations of Augmented Cognition. Neuroergonomics and Operational Neuroscience: Held as Part of HCI International 2009 (2009)

Eye movement recordings do not tell us whether observers are 'really looking' or whether they are paying attention to something else than the visual environment. We want to determine whether an observer's main current occupation is visual or not by investigating fixation patterns and EEG. Subjects were presented with auditory and visual stimuli. In some conditions, they focused on the auditory information whereas in others they searched or judged the visual stimuli. Observers made more fixations that are less cluttered in the visual compared to the auditory tasks, and they were less variable in their average fixation location. Fixated features revealed which target the observers were looking for. Gaze was not attracted more by salient features when performing the auditory task. 8-12 Hz EEG oscillations recorded over the parieto-occipital regions were stronger during the auditory task than during visual search. Our results are directly relevant for monitoring surveillance workers.

In this article, the design, fabrication, and on-wafer test of X-Band and 2&ndash;18 GHz wideband high-power SPDT MMIC switches in AlGaN-GaN technology are presented. The switches have demonstrated state-of-the-art performance and RF fabrication yield better than 65&percnt;. Linear and power measurements for different control voltages have been reported and an explanation of the dependence of the power performances on the control voltage is given. In particular, the X-band switch exhibits a 0.4 dB compression level at 10 GHz when driven by a 38 dBm input signal. The wideband switch shows a compression level of 1 dB at an input drive higher than 38 dBm across the entire bandwidth. &copy; 2009 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2009.
Application of Wavelet Packet and Data-Driven in Fault Diagnosis for Hydropower Units
Authors: Liao Wei, Wang Zhentao, Han Pu
Venue: Proceedings of the 2009 IITA International Conference on Services Science, Management and Engineering (2009)

Vibration is one of the most common faults for hydropower units; traditional signal processing methods can not effectively extract the eigenvectors of the fault signals. In this paper, using wavelet packet analyze the spectrum of the vibration signals for hydropower units, extracting the frequency eigenvectors of the signal and use them as the classification data, taking good advantage of the feature of the data and extracting the quantified values of the contribution which the indicators made to classifications, what’s more, taking the weighted distances in place of Euclidean distances, establishing the iterative algorithm to search optimal representative points. Therefore, we can apply this algorithm to diagnosis the fault for hydropower units. The experiment results shows that it is very appropriate for us to use the proposed method to diagnosis the vibration fault for hydropower units.
Wavelet-Based Feature Extraction for Handwritten Numerals
Authors: Diego Romero, Ana Ruedin, Leticia Seijas
Venue: Proceedings of the 15th International Conference on Image Analysis and Processing (2009)

We present a novel preprocessing technique for handwritten numerals recognition, that relies on the extraction of multiscale features to characterize the classes. These features are obtained by means of different continuous wavelet transforms, which behave as scale-dependent bandpass filters, and give information on local orientation of the strokes. First a shape-preserving, smooth and smaller version of the digit is extracted. Second, a complementary feature vector is constructed, that captures certain properties of the digits, such as orientation, gradients and curvature at different scales. The accuracy with which the selected features describe the original digits is assessed with a neural network classifier of the multilayer perceptron (MLP) type. The proposed method gives satisfactory results, regarding the dimensionality reduction as well as the recognition rates on the testing sets of CENPARMI and MNIST databases; the recognition rate being 92.60 % for the CENPARMI data-base and 98.22 % for the MNIST database.
