Structural Aspects of Business Process Diagram Abstraction
Authors: Sergey Smirnov
Venue: Proceedings of the 2009 IEEE Conference on Commerce and Enterprise Computing (2009)

As companies more and more often turn todocumenting their business processes in models, the task ofmanaging large model collections becomes essential. Thereis a number of techniques simplifying this task, e.g., constructionof customized process views and business processmodel abstraction. The latter aims at deriving abstract processrepresentations from existing low-level models omitting detailsirrelevant for the current task. A number of papers on processmodel abstraction conceptualized the abstraction problem andproposed algorithms handling simplistic models. To the bestof our knowledge there is no work discussing abstraction ofmodels in BPMN. In this paper we present an abstractionapproach, addressing specific features of BPMN 1.2. Theabstraction approach is order-preserving and is capable ofhandling graph-structured process models.

Authors: Ivanka Terzic, Alois Zoitl, Martijn Rooker, Thomas Strasser, Pavel Vrba, Vladimir Mařík
Venue: Proceedings of the 4th International Conference on Industrial Applications of Holonic and Multi-Agent Systems: Holonic and Multi-Agent Systems for Manufacturing (2009)

A future adaptive and reconfigurable manufacturing system has to address, beside the requirements for agile and fast reaction to sudden and unpredictable changes in production demands, also the problem of user acceptance and understanding of such highly intelligent reconfigurable systems. Thus, the usability is a major criterion for the design of future manufacturing systems. The design and development of both the architecture for simplifying of development of such systems and the advanced diagnostic, monitoring, and human-interaction system will provide an easy maintenance and increased acceptance of such systems.
Attribution of Identity in Autonomous Action of Remotely Operated Robot
Authors: Yugo Takeuchi, Hikaru Nakagami
Venue: Proceedings of the 3d International Conference on Online Communities and Social Computing: Held as Part of HCI International 2009 (2009)

This paper investigates how people attribute individual autonomy to a remotely operated robot. An experiment was conducted in which participants remotely operated a goalkeeper robot to defend its goal from the kicker robot. Participants were assigned to two types of experimental conditions. Participants assigned to the first condition watched video images that captured the motion of the kicker robot from behind the goal. Participants assigned to the second condition watched video images of the kicker robot from the position of the goalkeeper robot. The result suggests that people are not concerned with the avatar's autonomy when they are focused on the avatar's situation.
Error analysis of the TempEval temporal relation identification task
Authors: Chong Min Lee, Graham Katz
Venue: Proceedings of the Workshop on Semantic Evaluations: Recent Achievements and Future Directions (2009)

The task to classify a temporal relation between temporal entities has proven to be difficult with unsatisfactory results of previous research. In TempEval07 that was a first attempt to standardize the task, six teams competed with each other for three simple relationidentification tasks and their results were comparably poor. In this paper we provide an analysis of the TempEval07 competition results, identifying aspects of the tasks which presented the systems with particular challenges and those that were accomplished with relative ease.

Authors: Zhang Shibin, Sun Xiang, Qin Zhi
Venue: Proceedings of the 2009 Second International Symposium on Electronic Commerce and Security - Volume 01 (2009)

In this paper, taking subjective trust as the background in the open network system, the subjective trust is analyzed. It shows the subjective trust has the subjectivity, uncertainty and randomness etc., which shows fuzziness. Based on the fuzzy reasoning theory, the subjective trust evaluation model based on fuzzy reasoning is studied and proposed by the aid of local information and the associated analysis and confirmation of this model is discussed in this paper. In this paper, we concentrate on studying the rules and reasoning procedures of this subjective trust evaluation model, the evaluation of subjective trust is solved finally. Through simulation, the feasibility and the rationality of this subjective trust evaluation model are further confirmed. At the same time, this model proposed in this paper enlightens also a new way for this subjective trust evaluation model of current complex network system.
Network Classes and Graph Complexity Measures
Authors: Matthias Dehmer, Stephan Borgert, Frank Emmert-Streib
Venue: Proceedings of the 2008 First International Conference on Complexity and Intelligence of the Artificial and Natural Complex Systems. Medical Applications of the Complex Systems. Biomedical Computing (2008)

In this paper, we propose an information-theoretic approach to discriminate graph classes structurally. For this, we use a measure for determining the structural information con- tent of graphs. This complexity measure is based on a special information functional that quanti¯es certain structural information of a graph. To demonstrate that the complexity measure captures structural information meaningfully, we interpret some numerical results.
Design patterns for supporting RTSJ component models
Authors: Mohammed Alrahmawy, Andy Wellings
Venue: Proceedings of the 7th International Workshop on Java Technologies for Real-Time and Embedded Systems (2009)

The Real-time Specification of Java (RTSJ) has new memory management and scheduling models. These models require modification to existing software models and patterns or even the invention of new ones in order to be able to provide the patterns necessary to build reusable software components. In this paper we present a new memory model pattern associated with a set of integrated patterns and with it build simple and configurable software components.
An Efficient Algorithm to Mine Unordered Trees
Authors: Yun Li, Xin Guo, Yunhao Yuan, Jia Wu, Ling Chen
Venue: Proceedings of the 2009 Eigth IEEE/ACIS International Conference on Computer and Information Science (2009)

Mining unordered trees are very useful in domains like XML Date, Biological Information, Web Structure, etc. In this paper, we introduce an efficient algorithm UTMiner (Unordered Trees Miner). As the trees are unordered, in order to avoid mining the same subtrees, an efficient unordered trees standardization is first introduced to transform the unordered trees into the standard subtrees. Then UTMiner is used to get all standardized subtrees. UTMiner builds a multilayered data structure based on subtree vector and the hash table so it reduces isomorphism time in the mining process. It requires only one database scanning so it reduces the scanning times and improves the efficiency, particularly in a large database’s mining process. Many experiments have shown that the UTMiner is feasible and more efficient than other.
Poly-logarithmic Independence Fools AC^0 Circuits
Authors: Mark Braverman
Venue: Proceedings of the 2009 24th Annual IEEE Conference on Computational Complexity (2009)

We prove that poly-sized AC^0 circuits cannot distinguish a poly-logarithmically independent distribution from the uniform one. This settles the 1990 conjecture by Linial and Nisan [LN90]. The only prior progress on the problem was by Bazzi [Baz07], who showed that O(log^2 n)-independent distributions fool poly-size DNF formulas. Razborov [Raz08] has later given a much simpler proof for Bazzi’s theorem.
Comparison of Measurement of Accommodation between LCD and CRT at the Stereoscopic Vision Gaze
Authors: Masako Omori, Satoshi Hasegawa, Tomoyuki Watanabe, Kazuhiro Fujikake, Masaru Miyao
Venue: Proceedings of the 3rd International Conference on Virtual and Mixed Reality: Held as Part of HCI International 2009 (2009)

In the present study, we examined the visual accommodation of subjects who were gazing fixedly at 3D images from two different displays: a cathode ray tube (CRT) while wearing special glasses and a liquid crystal display (LCD) while not wearing special glasses. The subjects in this experiment were two healthy people aged 22 and 39 years, all with normal vision. The instrument objectively measured visual accommodative changes of the right eye in both binocular and natural viewing conditions. The results suggested that it was easy and comfortable to focus on both the LCD and CRT. When the subjects viewed the progressively receding target, their accommodation was about 0.8 D at the presumed furthest points, a level at which the ciliary muscle is relaxed. The accommodative power differed by about 1.5 D from the near to far point. Thus, the ciliary muscle is repeatedly strained and relaxed while the subject views the moving target.
A Comparative Study of VoIP Standards with Asterisk
Authors: Pablo Montoro, Eduardo Casilari
Venue: Proceedings of the 2009 Fourth International Conference on Digital Telecommunications (2009)

Since the apparition of Voice over IP (VoIP), many standards (mainly signaling protocols and codecs) have arisen with the aim of enabling voice calls through data networks. This paper describes a comparative study to evaluate the performance of a representative set of these standards when transmitting voice streams in a packet network. Asterisk PBX software is employed to define a testbed that allows to monitor diverse performance parameters in actual VoIP connections after the call establishment phase. Performed tests include the use of SIP and IAX (with and without trunking) signaling protocols as well as four different codecs. The obtained Results (expressed in terms of processor utilization, memory usage and network bandwidth consumption) show the clear benefits of employing IAX with trunking.

Weyuker's Properties, Language Independency and Object Oriented Metrics
Authors: Sanjay Misra
Venue: Proceedings of the International Conference on Computational Science and Its Applications: Part II (2009)

Weyuker proposed the nine properties to evaluate software complexity measures at a time when procedural languages were dominant; however, several researchers have used these properties to evaluate object oriented metrics although the object-oriented (OO) features are entirely different in nature. In this paper, we evaluate each of Weyuker's properties for its effective evaluation and relevance for OO metrics. In addition, we evaluate eleven OO metrics against language independency and additive property. A set of additional properties for object oriented metrics are also summarized in this paper.
Cellular Automata-Based S-Boxes vs. DES S-Boxes
Authors: Miroslaw Szaban, Franciszek Seredynski
Venue: Proceedings of the 10th International Conference on Parallel Computing Technologies (2009)

In the paper we use recently proposed cellular automata (CA) - based methodology [9] to design 6x4 S-boxes functionally equivalent to S-boxes used in current cryptographic standard known as DES. We provide an exhaustive experimental analysis of the proposed CA-based S-box in terms of non-linearity, autocorrelation, balance and strict avalanche criterion, and compare it with DES S-boxes. We show that the proposed CA-based S-box has cryptographic properties comparable or better than classical S-box tables. The interesting feature of the proposed S-box is a dynamic flexible structure fully functionally realized by CA, while the classical DES S-box is represented by predefined unchangeable table structure.

This study has interesting implications for designing user interfaces of search applications.
Cognitive Load Measurement from User's Linguistic Speech Features for Adaptive Interaction Design
Authors: M. Asif Khawaja, Fang Chen, Christine Owen, Gregory Hickey
Venue: Proceedings of the 12th IFIP TC 13 International Conference on Human-Computer Interaction: Part I (2009)

An adaptive interaction system, which is aware of the user's current cognitive load (CL), can change its response, presentation and flow of interaction material accordingly, to improve user's experience and performance. We present a speech content analysis approach to CL measurement, which employs users' linguistic features of speech to determine their experienced CL level. We show analyses of several linguistic features, extracted from speech of personnel working in computerized incident control rooms and involved in highly complex bushfire management tasks in Australia. We present the results of linguistic features showing significant differences between the speech from the cognitively low load and high load tasks. We also discuss how the method may be used for user interface evaluation and interaction design improvement.

Authors: Huang Yongzhong, Zhang Xiaowen, Guo Shaozhong, Lan Mingjing
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 03 (2009)

The traditional transactional workflow is conditioned by complex information environment (collaboration of various applications, long-running transaction), because it is designed for short transaction. Thus some kinds of exception handling method will be introduced into the WfMS to resolve the exception when the workflow is running. The compensation protocol in BPEL provides the ability for flexible control of the reversal. In this paper we analyze the difference between the transaction in WfMS, traditional transaction and advanced transaction, make research on the core conception and feature of the distributed transaction, besides, it elaborates on the analysis of the advanced transactions models and BPEL’s transaction mechanism with a specific example.

PSINS: An Open Source Event Tracer and Execution Simulator for MPI Applications
Authors: Mustafa M. Tikir, Michael A. Laurenzano, Laura Carrington, Allan Snavely
Venue: Proceedings of the 15th International Euro-Par Conference on Parallel Processing (2009)

The size of supercomputers in numbers of processors is growing exponentially. Today's largest supercomputers have upwards of a hundred thousand processors and tomorrow's may have on the order one million. The applications that run on these systems commonly coordinate their parallel activities via MPI; a trace of these MPI communication events is an important input for tools that visualize, simulate, or enable tuning of parallel applications. We introduce an efficient, accurate and flexible trace-driven performance modeling and prediction tool, PMaC's Open Source Interconnect and Network Simulator (PSINS), for MPI applications. A principal feature of PSINS is its usability for applications that scale up to large processor counts. PSINS generates compact and tractable event traces for fast and efficient simulations while producing accurate performance predictions. It also allows researchers to easily plug in different event trace formats and communication models, allowing it to interface gracefully with other tools. This provides a flexible framework for collaboratively exploring the implications of constantly growing supercomputers on application scaling, in the context of network architectures and topologies of state-of-the-art and future planned large-scale systems.
Realizability of Real-Time Logics
Authors: Laurent Doyen, Gilles Geeraerts, Jean-Francois Raskin, Julien Reichert
Venue: Proceedings of the 7th International Conference on Formal Modeling and Analysis of Timed Systems (2009)

We study the realizability problem for specifications of reactive systems expressed in real-time linear temporal logics. The logics we consider are subsets of MITL (Metric Interval Temporal Logic), a logic for which the satisfiability and validity problems are decidable, a necessary condition for the realizability problem to be decidable. On the positive side, we show that the realizability of LTL extended with past real-time formulas is decidable in 2EXPTIME, with a matching lower bound. On the negative side, we show that a simple extension of this decidable fragment with future real-time formulas leads to undecidability. In particular, our results imply that the realizability problem is undecidable for ECL (Event Clock Logic), and therefore also for MITL.
Glasses-Free 3D Image Viewer by Handmade DIY Craft
Authors: Takashi Ohara, Kunio Sakamoto
Venue: Proceedings of the 8th International Conference on Entertainment Computing (2009)

We developed a glasses-free 3D stereoscopic display using an LCD display panel, a view control film and a grating film for stereoscopic viewing. The display screen is divided in half in order that left and right regions provide the stereoscopic images for left and right eyes. Because both stereoscopic images are not in the same position, it is difficult for the observer to view the 3D image by the stereoviewing. The grating film can solve this problem because it shifts both left and right images to the same position. Moreover the view control film can give us glasses-free 3D viewing. As the result, the observer can watch overlapped stereoscopic images for left and right eyes without special glasses such as polarized glasses.
Learning objects in theory and practice: A vision from Mexican University teachers
Authors: MariCarmen González-Videgaray, Gregorio Hernández-Zamora, Jesús H. del-Río-Martínez
Venue: Computers Education (2009)

Drawing on the experience of development and use of a virtual learning environment (VLE) at a public Mexican university, this article explores the tension between the most common definitions and attributes of learning object (LO) in the mainstream literature, and the teacher's practices around the creation and incorporation of LOs in the VLE. This experience shows that attempting to define LOs from strictly technical or industrial parameters might be limiting in the context of educational institutions, since teachers are developing and using LOs effectively, despite their little adherence to prescriptive definitions. Yet it is important to support teachers in order to take advantage of the interactive and multimedia potentialities afforded by this technology, instead of using it mostly for delivering static content.
Multi-parameter Optimum Combination Model of Predicting Land Demand for Construction Use of City
Authors: Sheng Luo
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 03 (2009)

This paper according to the intrinsic relationship between demand land for construction and socio-economic development indicators, presents a models to forecast the demand for construction: a multi-parameter nonlinear model for forecasting demand for construction.In the multi-parameter nonlinear model, Population, GDP, Financial Expenditure and Total Investment in Fixed Assets, were selected as the independent variable, while construction land area was selected as the dependent variable. An improved optimum combination forecasting method was used to produce a multi-parameter nonlinear model. This method calculates the value of each coefficient based on the precision contribution of the single variable simulation model to the predicted increments of construction land area. And then a correct coefficient is used to correct forecast results. As a result, construction land demand is satisfactorily obtained. The forecast of construction land in future could help the relative departments of government to plan lands utilize so that avoid the waste of land resource.
Multimodal Biometric Identification Approach Based on Face and Palmprint
Authors: Cheng Lu, Jisong Wang, Miao Qi
Venue: Proceedings of the 2009 Second International Symposium on Electronic Commerce and Security - Volume 02 (2009)

Multimodal biometric identification technique utilizes two or more individual modalities to improve the identification accuracy and overcome some problems existing in conventional unimodal methods. This paper presents a multimodal biometric identification approach based on the features of face and palmprint. Two feature extraction methods are employed, one is based on the statistics properties (SP) of the biometric image and the other is the classical two-dimensional principal component analysis (2DPCA). The minimal distance rule (MDR) is adopted for fusion at the matching score level. We compare the results of the multimodality identification with the results of the unimodal face and palmprint identification. The experimental results show that the performance of multimodality outperforms the unimodal identification and the accuracy can reach 100% based on ORL face database and PolyU palmprint database using the fusion rule at the matching score level.
Syntactic parser combination for improved dependency analysis
Authors: Francis Brunet-Manquat
Venue: Proceedings of the 3rd Workshop on RObust Methods in Analysis of Natural Language Data (2004)

The goal of this article is to present our work about a combination of several syntactic parsers to produce a more robust parser. We have built a platform which allows us to compare syntactic parsers for a given language by splitting their results in elementary pieces, normalizing them, and comparing them with reference results. The same platform is used to combine several parsers to produce a dependency parser that has larger coverage and is more robust than its component parsers. In the future, it should be possible to "compile" the knowledge extracted from several analyzers into an autonomous dependency parser.
