Risk Assessment Model of Automobile Defect Based on Gray Theory
Authors: Yan Wang, Yun-Song Wang, Jin-Huan Zhang
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 02 (2009)

Risk assessment of automobile defect is classifying safety related risk level of manufacturing or designing defect. To carry out equivalent study between defect risk and failure defect, a risk flow route of automobile defect is developed introducing ETA method. A SPN function for risk assessment is setup based on Characteristics of automobile defect risk, and 3D matrix graph is introduced to describe overall risk. According to the scattered and fluctuant characteristics of automobile defect data, a risk forecast method based on gray theory is discussed. A risk assessment model of automobile defect is built; forecast of risk possibility is based on failure data. The model is corrected by residual discrimination. It is found that on gathering actual failure data from after-sales service, the gray model has a favorable applicability for forecast of risk possibility.

Enterprise governance of information technology is a relatively new concept that is gaining traction in both the academic and practitioner worlds. Going well beyond the implementation of a superior IT infrastructure, Enterprise Governance of Information Technology is about defining and embedding processes and structures throughout the organizations that enable both business and IT people to execute their responsibilities, while maximizing the value created from their IT-enabled investments. At the forefront of the field, the authors draw from years of research and advising corporate clients to present the first comprehensive resource on the topic. Featuring numerous case examples from companies around the world, the book integrates theoretical advances and empirical data with practical application, including in-depth discussion of such frameworks as COBIT and VALIT, which are used to measure and audit the value of IT investments and ensuring regulatory compliance. A variety of elements, including executive summaries and sidebars, extensive references, and questions and activities (with additional materials available on-line) ensure that the book will be an essential resource for professionals, researchers, and students alike.
State Feedback Controller Design for a Class of Networked Control System with Uncertain Time-Delay
Authors: JiHua Wang, Ling Dong, Yan Bai
Venue: Proceedings of the 2009 Asia-Pacific Conference on Information Processing - Volume 01 (2009)

The networked control system (NCS) with uncertain time-delay is modeled as a discrete time system with uncertain parameters. For the NCS in which the time-delay is less than one sampling period, between one sampling period and two sampling periods, between k-1 sampling periods and k sampling periods (k is a positive integer greater than or equal to three), we provide sufficient conditions ensuring the systems asymptotically stable and design state feedback controllers which stabilize the systems. Numerical examples are given to illustrate the effectiveness of our results.
Evaluation of the Teacher Quality in University Based on the Unascertained Measurement Model
Authors: Jin Zhu, Hu Xujie
Venue: Proceedings of the 2009 Second International Symposium on Electronic Commerce and Security - Volume 02 (2009)

Teacher quality is the fountainhead of gaining competitive power for the university. Therefore, evaluating the teacher quality of the university is the premise the and foundation for the university to obtain the competitive advantage and it is also an important guarantee of maintaining its competitive advantage and the realization of sustainable development. Teacher is the pusher of the innovation and the high quality education of the university. Neglecting the establishment of the evaluation to the university will cause the university education efficiency being low and the university's sustainable innovation being immersed in trouble. The effective teacher quality evaluation can help the university get the sustainable innovation. Though introducing the characteristics of the teacher quality, this article gave us a new method to inspect the teacher’s quality. The unascertained measurement model was used to inspect that whether or not the university has the high quality teacher, which is useful for the university to get the effective and efficient development. Moreover, the universities were given an effective and helpful inspection to enhance the teacher’s quality.
Augmented Interactions: A Framework for Adding Expressive Power to GUI Widgets
Authors: Jared Cechanowicz, Carl Gutwin
Venue: Proceedings of the 12th IFIP TC 13 International Conference on Human-Computer Interaction: Part I (2009)

The basic elements of WIMP interfaces have proven to be robust components for building interactive systems, but these standard interactors also have limitations. On many occasions, researchers have introduced augmented GUI elements that are capable of more expressive interactions and that are better suited to user tasks. Although many of these novel designs have been effective, augmented interactors are still invented in an ad-hoc fashion, and there is no systematic way of thinking about or designing augmentations. As a result, there is little understanding of the principles underlying augmentation, the relationships between different designs, or the possibilities for creating new interactors. In this paper we present a framework that specifies elemental interactions with WIMP components and identifies the possible ways in which augmentations can occur. We show the explanatory and generative power of the framework by analysing existing and novel augmented interactions.

Authors: Angelos-Christos Anadiotis, Apostolos Apostolaras, Dimitris Syrivelis, Thanasis Korakis, Leandros Tassiulas, Luis Rodriguez, Maximilian Ott
Venue: Proceedings of the 4th ACM international workshop on Experimental evaluation and characterization (2009)

The gradually growing need for testbed use so as networking algorithms to be validated in real environments, has given rise to optimal utilization of testbed resources. Despite the fact that, many laboratories around the globe have deployed testbeds, so as experimenters have the opportunity to test their algorithms, the majority of those testbeds suffer from bad management that prevents users from efficiently exploiting testbed's resources. Moreover, as the number of testbed users increases, experimenters needs for more sophisticated allocation of testbed resources are growing. Toward, this direction, we propose a managerial framework that exploits testbed utilization by introducing slicing over frequency spectrum. This new framework will allow a more sophisticated way to optimally control and manage network resources of a testbed. Lab's website: http://nitlab.inf.uth.gr

Authors: Sheng Li, Ren-jie Qin
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 02 (2009)

Hard asphalt mixture is of excellent high-temperature stability, water stability, and anti-fatigue properties. This article studies the application and related construction technology of hard asphalt mixture starting with the performance of hard asphalt mixture, putting forward its application in some areas as high-temperature area, heavy duty road, long and large longitudinal of mountains area, the covering of deck etc., including some research on construction techniques of the hard asphalt mixture as temperature control, transportation, paving, compaction, quality control etc. Research shows that the asphalt pavement rutting and shear damage can be solved better in the area with torridity in summer when the hard asphalt applies in the medium and the lower base course of asphalt pavement, and strictly controlling the temperature scope of the request in various construction processes is the key technology of hard asphalt construction.
Single-rate near lossless compression of animated geometry
Authors: Rachida Amjoun, Wolfgang Straíer
Venue: Computer-Aided Design (2009)

Representing mesh geometry in local rather than the world coordinate systems is very useful in many 3D animation processing applications. One can investigate the representation of vertex locations relative to a local coordinate frame (LCF) in the compression of dynamic 3D meshes. Unlike the world coordinates, which scatter in a wide range and show non-linear behavior of the vertices, the local coordinates exhibit a large clustering behavior of the vertex over time. This property is very useful for exploiting a large coherence over the vertex trajectory and between neighboring vertices. In this paper, we discuss the use of the LCF in static and animated mesh encoding and we introduce a new connectivity-guided predictive scheme for single-rate compression for animated meshes. The proposed geometry encoding strategy is based on a region growing encoding order, and only the differences between original and predicted locations are encoded in a local coordinate system, which splits into two tangential and one normal components. The approach is simple, efficient, and well-suited for real time applications.

Authors: Hao Li, Guofu Luo, Jun Ma, Bin Wang
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

Building a dynamic performance evaluation model is an important part in the management of collaborative manufacturing process. By analyzing the current evaluating method, this paper firstly put forward the mathematical model of dynamic performance evaluation of collaborative knowledge chain, and built a performance evaluation indices model. Then, the weight factors of performance evaluation model were calculated by using Delphi method. Thirdly, performance values of each knowledge unit and collaborative knowledge chain were calculated, and accordingly figures for performance values can be built. Finally, a case study was carried out.
Reconfigurable Multithreading Architectures: A Survey
Authors: Pavel G. Zaykov, Georgi K. Kuzmanov, Georgi N. Gaydadjiev
Venue: Proceedings of the 9th International Workshop on Embedded Computer Systems: Architectures, Modeling, and Simulation (2009)

This paper provides a survey on the existing proposals in the field of reconfigurable multithreading (ρMT) architectures. Until now, the reconfigurable architectures have been classified according to implementation or architectural criteria, but never based on their ρMT capabilities. More specifically, we identify reconfigurable architectures that provide implicit, explicit or no architectural support for ρMT. For each of the proposals, we discuss the conceptual model, the limitations and the typical application domains. We also summarize the main design problems and identify some key research questions related to highly efficient ρMT support. In addition, we discuss the application prospectives and propose possible research directions for future investigations.
Examining user behavioral response to SMS ads: Implications for the evolution of the mobile phone as a bona-fide medium
Authors: Ran Wei, Hao Xiaoming, Ji Pan
Venue: Telematics and Informatics (2010)

The mobile phone has emerged as the newest medium of interactive marketing and advertising. Undoubtedly, users of a personal medium like the mobile phone play a decisive role in commercializing the mobile phone. By examining the major influences on mobile phone users' behavioral responses to SMS (Short Message Service) ads, this study seeks to shed light on the evolution of the mobile telephony as a bona-fide medium. Results of a survey of 407 mobile phone users in Singapore show that receiving SMS ads has become widespread, although the number of SMS ads received remains small. Furthermore, the instrumental and diversion motivations, prior consent, and privacy concerns directly affect the likelihood for users to pass the ads to others. Finally, when the users respond positively to SMS ads, the ads can be highly effective in triggering a purchase. Theoretical and practical implications of these findings are discussed.
Computational method for finding various solutions for a Quasilinear Elliptic Equation of Kirchhoff type
Authors: Manoj Kumar, Prashant Kumar
Venue: Advances in Engineering Software (2009)

This paper is concerned with the various solutions to the class of nonlocal boundary value problem with the help of finite element method for the class of Kirchhoff-type problem-M@!"@W|@?u|^2dx@Du=f(x,u)in@W,u=0on@?@Wwhere @W@?R^N is a bounded smooth domain, M:R^+->R is continuous and f:@WxR->R has subcritical growth. Kirchhoff equation does not appear to have been previously studied in detail computationally and it is hope that this paper will help to provide a new idea in this direction. Here we solved the nonlinear function f(x,u) with the help of Newton Raphson method and quasi-linear term by using Scaling Iterative Algorithm, forward difference and with the help of these schemes; we used finite element method to solve the Quasilinear Elliptic Equation of Kirchhoff Type and discussed the behaviour. In order to numerically confirm our theoretical results and to demonstrate the performance of the algorithm, we develop a MATLAB program for solving Kirchhoff-type problem.
Challenges for Sentence Level Opinion Detection in Blogs
Authors: Malik Muhammad Saad Missen, Mohand Boughanem, Guillaume Cabanac
Venue: Proceedings of the 2009 Eigth IEEE/ACIS International Conference on Computer and Information Science (2009)

The Opinion Detection from blogs has always been a challenge for researchers. However with the introduction of Blog track in TREC 2006, a considerable improvement has been seen in this field at document level. But now it is the time when researchers are thinking to shift their orientation from opinion finding at document level to opinion finding at sentence or passage level. In this paper, we investigate the challenges the researchers might face with sentence-level opinion detection and have tried to demonstrate them with few examples. Our work also includes annotation of a small set of opinionated sentences by two annotators. These Annotators annotate the sentences by labels Positive or Negative. The results of annotation prove that task of opinion detection on sentence-level is more challenging task than opinion detection on document level. In addition, we also discuss the importance of sentence-level opinion detection. Our work can give a new direction to researchers to think and work on.
Levelings and Geodesic Reconstructions
Authors: Jose Crespo
Venue: Proceedings of the 9th International Symposium on Mathematical Morphology and Its Application to Signal and Image Processing (2009)

This paper investigates some geodesic implementations that have appeared in the literature and that lead to connected operators. The focus is on two so-called self-dual geodesic transformations. Some fundamental aspects of these transformations are analyzed, such as whether they are actually levelings, and whether they can treat each grain or pore independently from the rest (connected-component locality). As will be shown, one of the geodesic self-dual reconstructions studied appears to be not a leveling. Nevertheless, it possesses a distinctive characteristic: it can process grains and pores in a connected-component local manner. The analysis is performed in the set or binary framework, although results and conclusions extend to (flat) gray-level operators.
Global asymptotic stability of delayed neural networks with discontinuous neuron activations
Authors: Liping Li, Lihong Huang
Venue: Neurocomputing (2009)

This paper investigates a class of delayed neural networks whose neuron activations are modeled by discontinuous functions. By utilizing the Leray-Schauder fixed point theorem of multivalued version, the properties of M-matrix and generalized Lyapunov approach, we present some sufficient conditions to ensure the existence and global asymptotic stability of the state equilibrium point. Furthermore, the global convergence of the output solutions are also discussed. The assumptive conditions imposed on activation functions are allowed to be unbounded and nonmonotonic, which are less restrictive than previews works on the discontinuous or continuous neural networks. Hence, we improve and extend some existing results of other researchers. Finally, one numerical example is given to illustrate the effectiveness of the criteria proposed in this paper.
Semi-supervised semantic role labeling
Authors: Hagen Fürstenau, Mirella Lapata
Venue: Proceedings of the 12th Conference of the European Chapter of the Association for Computational Linguistics (2009)

Large scale annotated corpora are prerequisite to developing high-performance semantic role labeling systems. Unfortunately, such corpora are expensive to produce, limited in size, and may not be representative. Our work aims to reduce the annotation effort involved in creating resources for semantic role labeling via semi-supervised learning. Our algorithm augments a small number of manually labeled instances with unlabeled examples whose roles are inferred automatically via annotation projection. We formulate the projection task as a generalization of the linear assignment problem. We seek to find a role assignment in the unlabeled data such that the argument similarity between the labeled and unlabeled instances is maximized. Experimental results on semantic role labeling show that the automatic annotations produced by our method improve performance over using hand-labeled instances alone.
Pointer Programs and Undirected Reachability
Authors: Martin Hofmann, Ulrich Schopp
Venue: Proceedings of the 2009 24th Annual IEEE Symposium on Logic In Computer Science (2009)

Pointer programs are a model of structured computation within LOGSPACE. They capture the common description of LOGSPACE algorithms as programs that take as input some structured data (e.g. a graph) and that store in memory only a constant number of pointers to the input (e.g. to the graph nodes). In this paper we study undirected s-t-reachability for a class of pure pointer programs in which one can work with a constant number of abstract pointers, but not with arbitrary data, such as memory registers of logarithmic size. In earlier work we have formalised this class as a programming language PURPLE that features a for all-loop for iterating over the input structure and thus subsumes other formalisations of pure pointer programs, such as Jumping Automata on Graphs JAGs and Deterministic Transitive Closure logic (DTC-logic) for locally ordered graphs. In this paper we show that PURPLE cannot decide undirected s-t-reachability, even though there does exist a LOGSPACE-algorithm for this problem by Reingold's theorem. As a corollary we obtain that DTC-logic for locally ordered graphs cannot express undirected s-t-reachability.
Automatic Cortical Sulcal Parcellation Based on Surface Principal Direction Flow Field Tracking
Authors: Gang Li, Lei Guo, Jingxin Nie, Tianming Liu
Venue: Proceedings of the 21st International Conference on Information Processing in Medical Imaging (2009)

Automatic parcellation of cortical surfaces into sulcal based regions is of great importance in structural and functional mapping of human brain. In this paper, a novel method is proposed for automatic cortical sulcal parcellation based on the geometric characteristics of the cortical surface including its principal curvatures and principal directions. This method is composed of two major steps: 1) employing the hidden Markov random field model (HMRF) and the expectation maximization (EM) algorithm on the maximum principal curvatures of the cortical surface for sulcal region segmentation, and 2) using a principal direction flow field tracking method on the cortical surface for sulcal basin segmentation. The flow field is obtained by diffusing the principal direction field on the cortical surface. The method has been successfully applied to the inner cortical surfaces of twelve healthy human brain MR images. Both quantitative and qualitative evaluation results demonstrate the validity and efficiency of the proposed method.
Optimum Sensors for `Chromaticity' Constancy in the Pixel
Authors: Sivalogeswaran Ratnasingam, Steve Collins
Venue: Proceedings of the 15th International Conference on Image Analysis and Processing (2009)

In machine vision systems recording the colour of an object is crucial for applications such as skin detection while it will enhance applications including colour based recognition and image retrieval. Unfortunately, almost none of the existing colour constancy algorithms have been designed to deal with the high dynamic ranges that can occur in external, naturally illuminated scenes. One algorithm that can deal with these scenes has been proposed by Finlayson and Drew. In this paper a method of assessing the performance of this algorithm, and equivalent algorithms, are proposed. The performance of this algorithm is then significantly improved by optimising the spectral response of the sensors used to obtain the data required by algorithm. Since the resulting performance is comparable to that of the human visual system it appears that this algorithm is capable of obtaining useful chromaticity information under highly varying illumination conditions.

Venue: Human Language Technology. Challenges of the Information Society: Third Language and Technology Conference, LTC 2007, Poznan, Poland, October 5-7, 2007, Revised Selected Papers (2009)

The aim of this paper is to develop (i) a general framework for the analysis of verb-noun (VN) collocations in English and Romanian, and (ii) a system for the extraction of VN-collocations from large tagged and annotated corpora. We identify VN-collocations in two steps: (i) by calculation of the frequent lexical co-occurrences of each VN-pair, and (ii) the identification of the most typical lexico-grammatical constructions in which each VN-pair is involved in.
