Authors: Long Wei, Boqin Gu, Xiu Feng, Fei Feng, Jian Huang
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 02 (2009)

Carbon graphite is a kind of main material of mechanical seal rings. The surface topography of end faces of seal rings has significant influence on the sealing behavior and the friction characteristic. In this paper, the modified Weierstrass-Mandelbrot function was introduced, which can characterize the topography of rough surfaces. The radial and circumferential profiles of end faces of M106K seal rings made of carbon-graphite impregnated furan resin were measured by AF-LI type stylus profilometer before and after 90-min wearing, and the fractal characteristics of the profiles were analyzed by the structure function method. The research results show that the surface profiles of M106K seal ring made of carbon-graphite impregnated furan resin are isotropic fractal and have different fractal dimensions before and after wearing.
Efficiently parsable extensions to tree-local multicomponent TAG
Authors: Rebecca Nesson, Stuart M. Shieber
Venue: Proceedings of Human Language Technologies: The 2009 Annual Conference of the North American Chapter of the Association for Computational Linguistics (2009)

Recent applications of Tree-Adjoining Grammar (TAG) to the domain of semantics as well as new attention to syntactic phenomena have given rise to increased interested in more expressive and complex multicomponent TAG formalisms (MCTAG). Although many constructions can be modeled using tree-local MCTAG (TL-MCTAG), certain applications require even more flexibility. In this paper we suggest a shift in focus from constraining locality and complexity through tree-and set-locality to constraining locality and complexity through restrictions on the derivational distance between trees in the same tree set in a valid derivation. We examine three formalisms, restricted NS-MCTAG, restricted Vector-TAG and delayed TL-MCTAG, that use notions of derivational distance to constrain locality and demonstrate how they permit additional expressivity beyond TL-MCTAG without increasing complexity to the level of set local MCTAG.
On the WOWA operator and its interpolation function
Authors: Vicenç Torra, Zhenbang Lv
Venue: International Journal of Intelligent Systems (2009)

The weighted ordered weighted averaging (WOWA) operator is one of the existing aggregation methods that can be used to fuse numerical data. The application of this operator to a set of data requires an interpolation function. In this paper, we present a few results about the sensitivity of the operator according to the interpolation method used. &copy; 2009 Wiley Periodicals, Inc.
Study on Engine Vibration Signal Denoising Method of SURE Block Threshold Based on DT-CWPT
Authors: Dinghai Wu, Peilin Zhang, Guoquan Ren, Bing Li, Jianjun Cao
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 01 (2009)

A mechanical vibration signal denoise method of SURE block threshold based on DT-CWPT was proposed. The mechanical condition monitoring is always aims to removing the background noise and preserving the useful information more effectively. The presented method chooses the threshold level and block size by minimizing Stein’s unbiased risk estimate which is more adaptive and superiorperformance and can obtain higher signal-to-noise than the common NeighCoeff. Simultaneously, combine the method with the DT-CWPT’s characteristic of approximately shift-invariant and optimal representation for the signal. And the method was applied to denoise the engine vibration signal which has the property of complex frequency domain and nonstationary and time-variant. Testing results show that the proposed method can effectively compress the noise and the denoised signal has better classification performance.

Near-infrared (NIR) sensing in flight applications can provide critical objective indicators of crew state. By monitoring oxy-hemoglobin concentrations, a NIR sensor can detect changes in flight crew physiology in response to both cognitive demands and extreme conditions related to flight applications, including gravity-induced loss of consciousness (G-LOC) and hypoxia. A custom NIR sensor was created for in-helmet monitoring of oxy-hemoglobin in flight. This wearable, wireless sensor addresses requirements for flight applications and was applied to a case study that examines the raw optical signal and oxy-hemoglobin response to Valsalva maneuvers performed at 1g.
General Search Algorithms for Energy Minimization Problems
Authors: Dmitrij Schlesinger
Venue: Proceedings of the 7th International Conference on Energy Minimization Methods in Computer Vision and Pattern Recognition (2009)

We describe a scheme for solving Energy Minimization problems, which is based on the A * algorithm accomplished with appropriately chosen LP-relaxations as heuristic functions. The proposed scheme is quite general and therefore can not be applied directly for real computer vision tasks. It is rather a framework, which allows to study some properties of Energy Minimization tasks and related LP-relaxations. However, it is possible to simplify it in such a way, that it can be used as a stop criterion for LP based iterative algorithms. Its main advantage is that it is exact --- i.e. it never produces a discrete solution that is not globally optimal. In practice it is often able to find the optimal discrete solution even if the used LP-solver does not reach the global optimum of the corresponding LP-relaxation. Consequently, for many Energy Minimization problems it is not necessary to solve the corresponding LP-relaxations exactly.
Remote Batch Invocation for Compositional Object Services
Authors: Ali Ibrahim, Yang Jiao, Eli Tilevich, William R. Cook
Venue: Proceedings of the 23rd European Conference on ECOOP 2009 --- Object-Oriented Programming (2009)

Because Remote Procedure Calls do not compose efficiently, designers of distributed object systems use Data Transfer and Remote Façade patterns to create large-granularity interfaces, hard-coded for particular client use cases. As an alternative to RPC-based distributed objects, this paper presents Remote Batch Invocation (RBI), language support for explicit client-defined batches. A Remote Batch statement combines remote and local execution: all the remote code is executed in a single round-trip to the server, where all data sent to the server and results from the batch are communicated in bulk. RBI supports remote blocks, iteration and conditionals, and local handling of remote exceptions. RBI is efficient even for fine-grained interfaces, eliminating the need for hand-optimized server interfaces. We demonstrate RBI with an extension to Java, using RMI internally as the transport layer. RBI supports large-granularity, stateless server interactions, characteristic of service-oriented computing.
Designing an Educational Game Facilitating Children's Understanding of the Development of Social Relationships Using IVAs with Social Group Dynamics
Authors: Wan Ching Ho, Kerstin Dautenhahn
Venue: Proceedings of the 9th International Conference on Intelligent Virtual Agents (2009)

Social relationships are fundamentally important to humans. Children are born into a family social structure and gradually they become part of a wider social structure including peers, in which each individual's relationships are affected by other relationships. To most people expressing appropriate non-verbal social behaviours when interacting with others in a virtual environment (VE) is natural and effortless as they do so daily in the physical world. There is a minority group, such as people diagnosed with autistic spectrum disorder, who encounter difficulties when carrying out this task because of impairments of specific skills regarding social communication and communication [1]. In this paper, we study the design of a system using advanced VE and IVA technologies with the goal to help children with autism to explore and better understand social dynamics occurring in social networks involving groups of people.
Keyboard before Head Tracking Depresses User Success in Remote Camera Control
Authors: Dingyun Zhu, Tom Gedeon, Ken Taylor
Venue: Proceedings of the 12th IFIP TC 13 International Conference on Human-Computer Interaction: Part II (2009)

In remote mining, operators of complex machinery have more tasks or devices to control than they have hands. For example, operating a rock breaker requires two handed joystick control to position and fire the jackhammer, leaving the camera control to either automatic control or require the operator to switch between controls. We modelled such a teleoperated setting by performing experiments using a simple physical game analogue, being a half size table soccer game with two handles. The complex camera angles of the mining application were modelled by obscuring the direct view of the play area and the use of a Pan-Tilt-Zoom (PTZ) camera. The camera control was via either a keyboard or via head tracking using two different sets of head gestures called "head motion" and "head flicking" for turning camera motion on/off. Our results show that the head motion control was able to provide a comparable performance to using a keyboard, while head flicking was significantly worse. In addition, the sequence of use of the three control methods is highly significant. It appears that use of the keyboard first depresses successful use of the head tracking methods, with significantly better results when one of the head tracking methods was used first. Analysis of the qualitative survey data collected supports that the worst (by performance) method was disliked by participants. Surprisingly, use of that worst method as the first control method significantly enhanced performance using the other two control methods.
Improving Cut-and-Choose in Verifiable Encryption and Fair Exchange Protocols Using Trusted Computing Technology
Authors: Stephen R. Tate, Roopa Vishwanathan
Venue: Proceedings of the 23rd Annual IFIP WG 11.3 Working Conference on Data and Applications Security XXIII (2009)

Cut-and-choose is used in interactive zero-knowledge protocols in which a prover answers a series of random challenges that establish with high probability that the prover is honestly following the defined protocol. In this paper, we examine one such protocol and explore the consequences of replacing the statistical trust gained from cut-and-choose with a level of trust that depends on the use of secure, trusted hardware. As a result, previous interactive protocols with multiple rounds can be improved to non-interactive protocols with computational requirements equivalent to a single round of the original protocol. Surprisingly, we accomplish this goal by using hardware that is not designed for our applications, but rather simply provides a generic operation that we call "certified randomness," which produces a one-way image of a random value along with an encrypted version that is signed by the hardware to indicate that these values are properly produced. It is important to stress that while we use this operation to improve cut-and-choose protocols, the trusted operation does not depend in any way on the particular protocol or even data used in the protocol: it operates only with random data that it generates. This functionality can be achieved with minor extensions to the standard Trusted Platform Modules (TPMs) that are being used in many current systems.We demonstrate our technique through application to cut-and-choose protocols for verifiable group encryption and optimistic fair exchange. In both cases we can remove or drastically reduce the amount of interaction required, as well as decrease the computational requirements significantly.

Authors: A. I. Avetisyan, S. S. Gaisaryan, V. V. Babkova
Venue: Programming and Computing Software (2009)

A technology of the iterative development of parallel programs and the corresponding development tools on the basis of the ParJava environment are considered. A benefit of the ParJava environment is that the the most part of the work can be done on a development computer using a model of the parallel program to be developed. This considerably reduces the the overheads in terms of time and resources used. The proposed technology is illustrated using the development of a parallel program for simulating intense atmospheric vortices as an example.

An Improved Algorithm for Image Decomposing Based on Separse Representation
Authors: Gang Wang, Shu-yan Liu, Zhi-feng Zhang, De-hua Wang, Liang Xiao
Venue: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 03 (2009)

A novel image decomposing algorithm is proposed in this paper, it can separate images into texture and cartoon parts under the complicated background. The main idea is the use of two appropriate dictionaries, one for the representation of textures, and the other for the cartoon parts assumed to be piecewise-smooth. The cartoon parts in the image can be sparsely represented by the local Ridgelet and the local Discrete Cosine transform is appropriate representation for texture parts. Furthermore, the use of Basic-Pursuit and Total-Variation regularization methods leads to the desired separation, along with noise removal as a by-product. The experiment results show that the image decomposition by the method is according with the human visual system.

Venue: Proceedings of the International Conference on Computational Science and Its Applications: Part II (2009)

In this paper, we suggest and implement an enhanced Wireless Broadband (WiBro) Net.-based five senses multimedia technology using Web-map-oriented mobile Mash-up. The WiBro Net. in this applicative technology supports and allows Web 2.0-oriented various issues such as user-centric multimedia, individual multimedia message exchange between multi-users, and a new media-based information and knowledge sharing / participation without spatiotemporal-dependency. To inspect applicability and usability of the technology, we accomplish various experiments, which include 1) WiBro Net.-based real-time field tests and 2) ISO 9241/11 and /10-based surveys on the user satisfaction by relative experience in comparison with the AP-based commercialized mobile service. As a result, this application provides higher data rate transmission in UP-DOWN air-link and wider coverage region. Also, its average System Usability Scale (SUS) scores estimated at 83.58%, and it relatively held competitive advantage in the specific item scales such as system integration, individualization, and conformity with user expectations.
Annotations with EARMARK for arbitrary, overlapping and out-of order markup
Authors: Silvio Peroni, Fabio Vitali
Venue: Proceedings of the 9th ACM symposium on Document engineering (2009)

In this paper we propose a novel approach to markup, called Extreme Annotational RDF Markup (EARMARK), using RDF and OWL to annotate features in text content that cannot be mapped with usual markup languages. EARMARK provides a unifying framework to handle tree-based XML features as well as more complex markup for non-XML scenarios such as overlapping elements, repeated and non-contiguous ranges and structured attributes. EARMARK includes and expands the principles of XML markup, RDFa inline annotations and existing approaches to overlapping markup such as LMNL and TexMecs. EARMARK documents can also be linearized into plain XML by choosing any of a number of strategies to express a tree-based subset of the annotations as an XML structure and fitting in the remaining annotations through a number of "tricks", markup expedients for hierarchical linearization of non-hierarchical features. EARMARK provides a solid platform for providing vocabulary-independent declarative support to advanced document features such as transclusion, overlapping and out-of-order annotations within a conceptually insensitive environment such as XML, and does so by exploiting recent semantic web concepts and languages.
How Not to Become a Buffoon in Front of a Shop Window: A Solution Allowing Natural Head Movement for Interaction with a Public Display
Authors: Omar Mubin, Tatiana Lashina, Evert Loenen
Venue: Proceedings of the 12th IFIP TC 13 International Conference on Human-Computer Interaction: Part II (2009)

The user interaction solution described in this paper was developed in the context of an Intelligent Shop Window (ISW) with an aim to offer a user the interaction solution where system response would be triggered by naturally gazing at products. We have analyzed a possibility to realize such a user interaction solution using gaze tracking and concluded that remote calibration free eye tracking is still a subject of academic research, but that head tracking could be used instead. We argue that conventional use of head tracking requires conscious intentional head movements and thus does not fit into the context of applications such as the ISW. We further describe our experiment aimed to explore how head movements relate to eye movements when looking at objects in a shop window context. We show large variability in head movement and that per individual the gaze-head data could well be approximated with a straight line. Based on these results we propose a new solution that enables natural gaze interaction by means of head tracking.
Feature Point Detection for Early Processing of Freehand Sketch Recognition
Authors: Jingwei Ye, Yongxin Zhu, Zhijun Li
Venue: Proceedings of the 2009 International Conference on Computational Intelligence and Natural Computing - Volume 01 (2009)

Freehand sketching is used widely in human's everyday life for expressing some ideas, especially in notebooks, PDAs and mobile phones. Therefore, the understanding of a sketched picture is the major problem in these devices. One of the most fundamental steps is converting the original digitized pen strokes in the sketch into the intended geometric objects using vertex detection and approximation. In this paper, we are working on the vertex detection for freehand sketching recognition, which would combine multiple sources of knowledge to provide robust early processing for freehand sketching.

Effectiveness of Stakeholder Identification Methods in Requirements Elicitation: Experimental Results Derived from a Methodical Review
Authors: Carla Pacheco, Ivan Garcia
Venue: Proceedings of the 2009 Eigth IEEE/ACIS International Conference on Computer and Information Science (2009)

One of the key challenges to producing high-quality software is identifying and understanding software requirements. In requirements acquisition, one of the crucial parts is stakeholder identification. This paper reports a methodical review of empirical studies concerning the effectiveness of stakeholder identification methods in requirements software, and the subsequent experimental evidence gathered from those studies. The following are the most considerable results: 1) studies which limit themselves to only proposing a list of possible stakeholders, 2) methods which not only indicate who the stakeholders can be but also studies their interactions and, 3) approaches dealing with studies that include an assessment of stakeholders. It should be noted that the studies from which these results were obtained have not been validated, and therefore the above-mentioned claims cannot be regarded as foolproof. However, these findings can be used by researchers as items of knowledge to be further investigated, and by practitioners in development software projects.
