Exploiting Browsing History for Exploratory Search
Authors: Wei-Lin Chen, Wei-Guang Teng
Venue: Proceedings of the Symposium on Human Interface 2009 on ConferenceUniversal Access in Human-Computer Interaction. Part I: Held as Part of HCI International 2009 (2009)

With the advance of information technologies, web search has become a necessary activity for most Internet users. Although current search engines are powerful enough to respond required search results in seconds, information seekers may still feel arduous to digest them when conducting the exploratory search. In other words, when users are unfamiliar with the domain of their goals or unsure about the ways to achieve their goals, they may need to read numerous pages before fully understand what they are searching for. In this work, we propose to fully exploit the browsing history to help users clarify their thoughts and discover new insights during the process of exploratory search. Specifically, interactive user interfaces of two different modes, i.e., the timeline mode and the relevance mode, are devised to provide users a vivid impression of their browsing history. Hopefully, the feasibility and usability of web search for users can be further improved.
Study of Operating Control Strategies for Hybrid Ground Source Heat Pump System with Supplemental Cooling Tower
Authors: Wang Jinggang, Gao Xiaoxia, Yin Zhenjiang, Li Fang
Venue: Proceedings of the 2009 IITA International Conference on Services Science, Management and Engineering (2009)

Ground source heat pump for cooling-dominated commercial buildings may utilize supplemental cooling towers to reduce system first cost and to improve system performance. The use of hybrid ground source heat pump (HGSP) can reduce the size of the ground-loop heat exchanger. Degradation of the heat pump performance due to the excess heat in the ground can be avoided by offsetting the annual load imbalance in the bore field. The operating performance and energy consumption of GSHP are analyzed in different operating and control strategies based on experimental results. A comparative study is presented that investigates the advantages and disadvantages of various system operating and control strategies.
Computational Mechanics: Natural Computation and Self-organization
Authors: James P. Crutchfield
Venue: Proceedings of the 8th International Conference on Unconventional Computation (2009)

The tutorial explores how nature's structure reflects how nature computes. It reviews intrinsic unpredictability (deterministic chaos) and the emergence of structure (self-organization) in natural complex systems. Using statistical mechanics, information theory, and computation theory, it develops a systematic framework for analyzing processes in terms of their causal architecture. This is determined by answering three questions: (i) How much historical information does a process store? (ii) In what architecture is that information stored? And (iii) how is the stored information used to produce future behavior? The answers to these questions tell one how a system intrinsically computes.

A Multi-Space Distribution (MSD) and two-stream tone modeling approach to Mandarin speech recognition
Authors: Yao Qian, Frank K. Soong
Venue: Speech Communication (2009)

Tone plays an important role in recognizing spoken tonal languages like Chinese. However, the discontinuity of F0 between voiced and unvoiced transition has traditionally been a hurdle in creating a succinct statistical tone model for automatic speech recognition and synthesis. Various heuristic approaches have been proposed before to get around the problem but with limited success. The Multi-Space Distribution (MSD) proposed by Tokuda et al. which models the two probability spaces, discrete for unvoiced region and continuous for voiced F0 contour, in a linearly weighted mixture, has been successfully applied to Hidden Markov Model (HMM)-based text-to-speech synthesis. We extend MSD to Chinese Mandarin tone modeling for speech recognition. The tone features and spectral features are further separated into two streams and corresponding stream-dependent models are trained. Finally two separated decision trees are constructed by clustering corresponding stream-dependent HMMs. The MSD and two-stream modeling approach is evaluated on large vocabulary, continuously read and spontaneous speech Mandarin databases and its robustness is further investigated in a noisy, continuous Mandarin digit database with eight types of noises at five different SNRs. Experimental results show that our MSD and two-stream based tone modeling approach can significantly improve the recognition performance over a toneless baseline system. The relative tonal syllable error rate (TSER) reductions are 21.0%, 8.4% and 17.4% for large vocabulary read and spontaneous and noisy digit speech recognition tasks, respectively. Comparing with the conventional system where F0 contours are interpolated in unvoiced segments, our approach improves the recognition performance by 9.8%, 7.4% and 13.3% in relative TSER reductions in the corresponding speech recognition tasks, respectively.
"You've Got IMs!" How People Manage Concurrent Instant Messages
Authors: Shailendra Rao, Judy Chen, Robin Jeffries, Richard Boardman
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part I: New Trends (2009)

Instant Messaging (IM) clients allow users to conduct multiple simultaneous conversations, which we term "concurrent IMs." In this study we investigate how adults manage concurrent IMs both in the workplace and within the context of a goal-directed, time-bounded recreational task. We discuss differences in behavior between engaging in a single IM conversation and engaging in concurrent IMs. We document the errors that arise as a consequence of concurrent IMs and identify four main strategies users employ to manage them: controlling the pace of conversations, limiting the number of simultaneous conversations, window management, and using tabbed IM windows. Finally, we explore the pros and cons of these strategies and examine design tradeoffs to enable effective space and attention management while minimizing disruption to the user.

Distributed Optical Fiber Sensor for Virtual Monitoring of Turbine Rotor's Temperature
Authors: Lin Wang, Xiaofei Yang, Buyun Sheng
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 01 (2009)

Rotor temperature is one of three important parameters in turbine’s running. To gain rotor's temperature data is in relation to turbine’s safe and smooth running. Optical fiber temperature sensor can resolve the question of getting the whole rotor’s temperature data well, it can prevent wiring problem and wasting time and funding by using single sensor. This measurement of rotor’s temperature is a more effective manner at the present time. Making steam turbine rotor’s temperature monitoring system on the Laboratory virtual instrument engineering workbench, the system is easily to facilitate reliable temperature data show. It develops the advantage of virtual instrument adequately with high precision and dependability and convenience, expands the traditional steam turbine rotor’s temperature monitoring system.
Neural correlates of stimulus reportability
Authors: Oliver J. Hulme, Karl F. Friston, Semir Zeki
Venue: Journal of Cognitive Neuroscience (2009)

Most experiments on the "neural correlates of consciousness" employ stimulus reportability as an operational definition of what is consciously perceived. The interpretation of such experiments therefore depends critically on understanding the neural basis of stimulus reportability. Using a high volume of fMRI data, we investigated the neural correlates of stimulus reportability using a partial report object detection paradigm. Subjects were presented with a random array of circularly arranged disc-stimuli and were cued, after variable delays (following stimulus offset), to report the presence or absence of a disc at the cued location, using variable motor actions. By uncoupling stimulus processing, decision, and motor response, we were able to use signal detection theory to deconstruct the neural basis of stimulus reportability. We show that retinotopically specific responses in the early visual cortex correlate with stimulus processing but not decision or report; a network of parietal/temporal regions correlates with decisions but not stimulus presence, whereas classical motor regions correlate with report. These findings provide a basic framework for understanding the neural basis of stimulus reportability without the theoretical burden of presupposing a relationship between reportability and consciousness.
Gradient-Based Optimization of Kernel Polarization for RBF Kernels
Authors: Jianfeng Xu, Lan Liu
Venue: Proceedings of the 2009 International Conference on Computational Intelligence and Natural Computing - Volume 01 (2009)

The problem of model selection for support vector machines using the RBF kernels is considered. We introduce a geometric view on maximizing kernel polarization, which intuitively shows why we choose kernel polarization as the criterion for kernel selection. After that we propose a gradient-based method for learning the width parameter of RBF kernels. This method is based on the possibility of computing the gradient of kernel polarization with respect to the width parameter. The proposed method is demonstrated with some UCI machine learning benchmark examples.

Construction of Subliminal Channel in ID-Based Signatures
Authors: Xin Xiangjun, Li Qingbo
Venue: Proceedings of the 2009 WASE International Conference on Information Engineering - Volume 02 (2009)

Based on the bilinear pairings, by covering the subliminal message with a shared temporary key generated from the time stamp, an ID-based signature scheme with subliminal channel is proposed, which can be proved to be secure in random oracle under the hardness assumption of computing Diffie-Hellman problem (CDHP). According to the construction of the proposed scheme, it is found that it is easy to construct a subliminal channel in the ID-based signatures. Therefore, the existence of the subliminal channel in the ID-based signatures can also limit the applications of the ID-based signatures.
Top-k Queries with Contextual Fuzzy Preferences
Authors: Patrick Bosc, Olivier Pivert, Amine Mokhtari
Venue: Proceedings of the 20th International Conference on Database and Expert Systems Applications (2009)

This paper deals with the interpretation of database queries with preference conditions of the form "attribute is low (resp. medium, high)" in the situation where the user is not aware of the actual content of the database but still wants to retrieve the best possible answers (relatively to that content). An approach to the definition of the terms "low", "medium" and "high" in a contextual and relative manner is introduced.
Detecting Race Conditions in One-Sided Communication of MPI Programs
Authors: Mi-Young Park, Sang-Hwa Chung
Venue: Proceedings of the 2009 Eigth IEEE/ACIS International Conference on Computer and Information Science (2009)

While one-sided communication introduced in MPI-2 is convenient to access remote memory, it is easier for programmers to make serious errors such as race conditions. Although there are several tools for detecting race conditions in MPI programs, these tools do not provide any mechanism to detect race conditions occurring in one-sided communication. In this paper, we present a technique to detect race conditions caused by unsafe accesses of one-sided operations. Our technique creates a mirror window whenever a process creates a window memory for one-sided communication, and uses it to monitor and detect race conditions. Whenever any one-sided operation accesses a window memory, the corresponding mirror window will be marked and checked to see if the window memory is unsafely accessed by any concurrent operation. In our experiment, we evaluate our technique using two public benchmark programs, and the results show that our technique can precisely detect race conditions. Therefore our technique is effective to detect race conditions in MPI programs and helpful to develop reliable parallel programs.
A New Wavelet Threshold Denoising Algorithm in Speech Recognition
Authors: Xuefei Liu
Venue: Proceedings of the 2009 Asia-Pacific Conference on Information Processing - Volume 02 (2009)

To obtain a high robust of speech recognition for noisy conditions, a new pre-processing stage based on wavelet thresholding algorithm is proposed in this paper. The purpose of using the DWT is to benefit from its localization property in the time and frequency domains. Compromise function is proposed compared with hard and soft thresholding function. A new thresholding value, Neyman-Pearson criterion is proposed compared with the commonly used Sqtwolog, Rigrsure, minimaxi criterion. MSE and SNR are given to evaluate the improvement of noisy speech recognition performance. The result shows that the Neyman-Pearson criterion can get a better performance especially at adverse conditions.
Novel Smith Predictor and Fuzzy Control for Networked Control Systems
Authors: Wencai Du, Feng Du
Venue: Proceedings of the 2009 Asia-Pacific Conference on Information Processing - Volume 01 (2009)

In order to effectively restrain the impact of network delay, aiming to time-variant, random and uncertain network delays, a new approach is proposed that new Smith predictor combined with fuzzy adaptive controller for the NCS. Because new Smith predictor does not include network delay, therefore, the network delays no need to be measured or identified on line. Based on CSMA/AMP (CAN Bus), the results of simulation show validity of the control scheme.

Matter Elements Evaluation Approach of Traffic Safety in Jiangsu Province Based on Information Entropy
Authors: Wei Deng, Bing Zhang, Jianrong Liu
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

There are more subjective factors and their weights can not been accurately decided in evaluation of road traffic safety. So, the matter element analysis model is applied in the paper to quantitate the evaluation indices, and the indices of road traffic safety are as the pending evaluation of multi-dimensional matter-element. And then, the weight coefficients of the evaluation indices is figured out from system of internal relations by applying the information entropy theory, and the subjective predilection of the evaluator is contained in the indices. Finally, the standard correlation of the evaluation of road traffic safety in Jiangsu Province is figured out and the level of the surrounding safety is gained. The result of the case is shown that the evaluation approach can accurately reflect the level of traffic safety development, so the approach is rational and feasible.
Integrating Wireless Sensor Networks into Enterprise Information Systems by Using Web Services
Authors: Ioakeim K. Samaras, John V. Gialelis, George D. Hassapis
Venue: Proceedings of the 2009 Third International Conference on Sensor Technologies and Applications (2009)

This paper proposes an advanced middleware solution to the problem of integrating a Wireless Sensor Network into the information system of an enterprise at a high abstraction level. This is achieved by using the proposed middleware which provides to the wireless sensors a Service Oriented Architecture connection to the Internet. The proposed middleware is based on the Device Profile for Web Services which is a Service Oriented Architecture technology at the device level. Since this technology is based on exchanging eXtensible Markup Language documents, a technique is utilized which compresses and reduces the data volume of such documents at a level that can be handled by the use of the resource constrained environment of the wireless sensors. By utilizing the proposed middleware which implements only the basic functions of the Device Profile for Web Services, we demonstrate how such a Wireless Sensor Network can be connected to the Internet achieving in this way its integration into an enterprise information system in which all its components conform to a Service Oriented Architecture standard.

Towards Semantic Modelling of Business Processes for Networked Enterprises
Authors: Karol Furdík, Marián Mach, Tomáš Sabol
Venue: Proceedings of the 10th International Conference on E-Commerce and Web Technologies (2009)

The paper presents an approach to the semantic modelling and annotation of business processes and information resources, as it was designed within the FP7 ICT EU project SPIKE to support creation and maintenance of short-term business alliances and networked enterprises. A methodology for the development of the resource ontology, as a shareable knowledge model for semantic description of business processes, is proposed. Systematically collected user requirements, conceptual models implied by the selected implementation platform as well as available ontology resources and standards are employed in the ontology creation. The process of semantic annotation is described and illustrated using an example taken from a real application case.
An Improved Lower Bound for the Complementation of Rabin Automata
Authors: Yang Cai, Ting Zhang, Haifeng Luo
Venue: Proceedings of the 2009 24th Annual IEEE Symposium on Logic In Computer Science (2009)

Automata on infinite words (ω-automata) have wide applications in formal language theory as well as in modeling and verifying reactive systems. Complementation of ω-automata is a crucial instrument in many these applications, and hence there have been great interests in determining the state complexity of the complementation problem. However, obtaining nontrivial lower bounds has been difficult. For the complementation of Rabin automata, a significant gap exists between the state-of-the-art lower bound 2^Ω(NlgN) and upper bound 2^O(kNlgN), where k, the number of Rabin pairs, can be as large as 2N. In this paper we introduce multidimensional rankings to the full automata technique. Using the improved technique we establish an almost tight lower bound for the complementation of Rabin automata. We also show that the same lower bound holds for the determinization of Rabin automata.
