Authors: Junliang Zhang, Li Lin, Shimin Zhang
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 02 (2009)

To ensure the safety of pipeline in the laying process, a tensioner system for a pipelaying vessel was designed to realize the constant control to pipeline. The tensioner uses two tracks to clamping pipeline, hydraulic system to drive upper track, AC servo motor to send the pipeline into the sea. In this design, as the critical component of the tensioner, track shoe was designed; furthermore its strength and deformation are analyzed. In the hydraulic system, after determining the parameter of all elements, the hydraulic cylinders on the stage of fast-forward, press, pressure maintaining, quick return, and synchronism were emulated. The result showed that the upper track was stably and the clamping tension was invariable. In driving system, fuzzy controller was adopted to control AC servo motor to output constant tension. According to simulation analysis, the result showed, during the working period of laying pipeline, the pipeline kept the constant tension.
An Adaptive Algorithm Based on Image Segmentation
Authors: Lang Liu, Yong Liu, Ying Lin
Venue: Proceedings of the 2009 Second International Symposium on Electronic Commerce and Security - Volume 02 (2009)

A new algorithm for adaptive threshold segmentation based on combining Fisher criterion with location optimization is proposed in this paper. Fisher criterion is taking as the fitness function of Genetic Algorithm (GA), and an adaptive method which is used to calculate crossover probability and mutation probability is presented. Meanwhile, we add a new local optimization operator that solves the disadvantages of poor astringency and premature occurrence in GA. Experimental results show that the algorithm achieves better performance on convergence and robustness，can efficiently segment the details and converge the optimal threshold.
Untangling Reverse Engineering with Logic and Abstraction
Authors: Andy King
Venue: Proceedings of the 25th International Conference on Logic Programming (2009)

Reverse engineering is the filthy end of the security industry; it is the business of extracting information from a program when the source is unavailable. Reversing is often necessary when performing a security audit on a product that relies on third-party software such as a library. Security engineers also reverse to reason about the latest malicious programs and devise antivirus software. Security engineers (and malicious hackers) do not attempt to reverse assembler into, say C, which is the traditional aspiration in reversing, but merely to understand the code to sufficient depth to locate a vulnerability.

Collaboration and the net generation: the changing characteristics of first year university students
Authors: Chris Jones, Ruslan Ramanau
Venue: Proceedings of the 9th international conference on Computer supported collaborative learning - Volume 1 (2009)

This paper reports on the first phase of research that investigates the Net generation entering university. The paper focuses on claims about the Net generation's relationship to collaboration and cooperation and the ways that this relationship is associated with technological rather than social processes. Based on a survey of first year students in five universities across a range of subjects and disciplinary areas, the paper concludes that we should be cautious about the claims that have been made about Net generation learners. It suggests that broad brush approaches to generational changes obscure the subtle but important differences between students. It also suggests that claims that there has been a step change in attitudes takes attention away from the kinds of choices that might be necessary in relation to variations that are indeed taking place amongst new cohorts of students.
MELB-KB: nominal classification as noun compound interpretation
Authors: Su Nam Kim, Timothy Baldwin
Venue: Proceedings of the 4th International Workshop on Semantic Evaluations (2007)

In this paper, we outline our approach to interpreting semantic relations in nominal pairs in SemEval-2007 task #4: Classification of Semantic Relations between Nominals. We build on two baseline approaches to interpreting noun compounds: sense collocation, and constituent similarity. These are consolidated into an overall system in combination with co-training, to expand the training data. Our two systems attained an average F-score over the test data of 58.7% and 57.8%, respectively.
Pathnodes Integration of Standalone Particle Filters for People Tracking on Distributed Surveillance Systems
Authors: Roberto Vezzani, Davide Baltieri, Rita Cucchiara
Venue: Proceedings of the 15th International Conference on Image Analysis and Processing (2009)

In this paper, we present a new approach to object tracking based on batteries of particle filter working in multicamera systems with non overlapped fields of view. In each view the moving objects are tracked with independent particle filters; each filter exploits a likelihood function based on both color and motion information. The consistent labeling of people exiting from a camera field of view and entering in a neighbor one is obtained sharing particles information for the initialization of new filtering trackers. The information exchange algorithm is based on path-nodes, which are a graph-based scene representation usually adopted in computer graphics. The approach has been tested even in case of simultaneous transitions, occlusions, and groups of people. Promising results have been obtained and here presented using a real setup of non overlapped cameras.

Based on LWM Algorithm to Evaluate the Choosing of Virtual Organization's Partner
Authors: Jinling Sun, Juan Pang
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 01 (2009)

When choosing partners, virtual enterprise always fixes attribute weights for every potential partner, and evolutionists have certain subjectivity and vagueness, which bring much trouble to the evaluation. To conquer this disadvantage, LWM Algorithm can be applied to converge the evaluation information to get complex-attribute evaluation and then choose the best partner eventually.
The Scheme Programming Language, 4th Edition, 4th edition
Authors: R. Kent Dybvig
Venue:  (2009)

Scheme is a general-purpose programming language, descended from Algol and Lisp, widely used in computing education and research and a broad range of industrial applications. This thoroughly updated edition of The Scheme Programming Language provides an introduction to Scheme and a definitive reference for standard Scheme, presented in a clear and concise manner. Written for professionals and students with some prior programming experience, it begins by leading the programmer gently through the basics of Scheme and continues with an introduction to some of the more advanced features of the language. The fourth edition has been substantially revised and expanded to bring the content up to date with the current Scheme standard, the Revised6 Report on Scheme. All parts of the book were updated and three new chapters were added, covering the language's new library, exception handling, and record-definition features. The book offers three chapters of introductory material with numerous examples, eight chapters of reference material, and one chapter of extended examples and additional exercises. All of the examples can be entered directly from the keyboard into an interactive Scheme session. Answers to many of the exercises, a complete formal syntax of Scheme, and a summary of forms and procedures are provided in appendixes. The Scheme Programming Language is the only book available that serves both as an introductory text in a variety of courses and as an essential reference for Scheme programmers.
Relative debugging in an integrated development environment
Authors: David Abramson, Clement Chu, Donny Kurniawan, Aaron Searle
Venue: Software&mdash;Practice Experience (2009)

Relative Debugging allows a user to compare the internal state of two programs as they run, making it possible to test whether two programs perform the same function given the same input. When implemented with a command line user interface, a relative debugger looks like traditional debugging tools with the addition of commands that describe which structures should be equivalent in the two programs. In this paper, we discuss relative debugging within an integrated development environment, and show that there are significant advantages over a command line form. We describe a pluggable, modular, architecture that works with a variety of different products, including Microsoft's Visual Studio, SUN's NetBeans, and IBM's Eclipse.

Constraint-based preferential optimization
Authors: S. Prestwich, F. Rossi, K. B. Venable, T. Walsh
Venue: Proceedings of the 20th national conference on Artificial intelligence - Volume 1 (2005)

We first show that the optimal and undominated outcomes of an unconstrained (and possibly cyclic) CP-net are the solutions of a set of hard constraints. We then propose a new algorithm for finding the optimal outcomes of a constrained CP-net which makes use of hard constraint solving. Unlike previous algorithms, this new algorithm works even with cyclic CP-nets. In addition. the algorithm is not tied to CP-nets, but can work with any preference formalism which produces a preorder over the outcomes. We also propose an approximation method which weakens the preference ordering induced by the CP-net, returning a larger set of outcomes, but provides a significant computational advantage. Finally, we describe a weighted constraint approach that allows to find good solutions even when optimals do not exist.
Research on Highway Emergency Vehicle Dispatching Model
Authors: Han-tao Zhao, Jun-qiang Leng, Guo-sheng Ma
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 02 (2009)

Rapid response is the core function of the highway emergency assistance system and the corresponding reasonable dispatching of rescue resource can shorten the response time. This paper deals with the problem of dispatching emergency vehicles on the highway. Optimization model is formulated by regarding the generalized response time as decision-making object. The parameters of model include travel time, weight coefficient , potential delay in response time and critertion for reassigning vehicle. In order to validate the optimization model, three dispatching strategies are contrasted under predigested conditions. The results show that the Model Serve dispatching improves the emergency response of highway and confirms the effectiveness of the proposed model. With few emergencies occurring in a row, the incident type and the criterion for reassigning vehicle of the model parameters have a greater impact on the effect of MS dispatching than the potential delay in response time and the penalty for delay.

Longitude: Centralized Privacy-Preserving Computation of Users' Proximity
Authors: Sergio Mascetti, Claudio Bettini, Dario Freni
Venue: Proceedings of the 6th VLDB Workshop on Secure Data Management (2009)

A "friend finder" is a Location Based Service (LBS) that informs users about the presence of participants in a geographical area. In particular, one of the functionalities of this kind of application, reveals the users that are in proximity. Several implementations of the friend finder service already exist but, to the best of our knowledge, none of them provides a satisfactory technique to protect users' privacy. While several techniques have been proposed to protect users' privacy for other types of spatial queries, these techniques are not appropriate for range queries over moving objects, like those used in friend finders. Solutions based on cryptography in decentralized architectures have been proposed, but we show that a centralized service has several advantages in terms of communication costs, in addition to support current business models. In this paper, we propose a privacy-aware centralized solution based on an efficient three-party secure computation protocol, named Longitude. The protocol allows a user to know if any of her contacts is close-by without revealing any location information to the service provider. The protocol also ensures that user-defined minimum privacy requirements with respect to the location information revealed to other buddies are satisfied. Finally, we present an extensive experimental work that shows the applicability of the proposed technique and the advantages over alternative proposals.

The studied result was reasonable and the classification degree for the ecological environment condition is consistent with the real situation, which was helpful for decision-making. Finally, the treatment measures were provided based on the evaluation result. In addition, this method can meet the change of factor configuration and handle with large-scale data automatically based on GIS.
A Variable Threats Based Self-Organization Scheme for Wireless Sensor Networks
Authors: Jian Zhong, Peter Bertok
Venue: Proceedings of the 2009 Third International Conference on Sensor Technologies and Applications (2009)

Self-organization is an important issue in wireless sensor networks because of the inherent unreliability of the network. Besides, variable threats in the networks can not be ignored. Extending battery life and enhancing robustness under variable threats are two essential aspects which need to be considered when a self-organization scheme is explored. In order to address these issues, a Redundant Nodes Selection scheme and a variable Threats Probability Estimation scheme are proposed in this paper. RNS is able to select redundant nodes that can be switched off without affecting overall sensing coverage. TPE is able to help a sensor node to choose the most suitable path and avoid high-threat neighbors in order to reduce packet loss. The scenario with RNS extended battery life by 30% to 50%, and postponed the occurrence of first partitioning in the network by 27% to 140%. TPE decreased packet loss by 225% to 400% when a high threat level was involved.
A Photo Correlation Map Using Mobile AP II for Scenario-Based Design
Authors: Yu-Li Chuang, Makoto Okamoto
Venue: Proceedings of the 1st International Conference on Human Centered Design: Held as Part of HCI International 2009 (2009)

We aim to explore a potentially valuable tool for scenario writing, focusing on the collection of user experiences organized around photos. We have developed a tool, Mobile AP II, to produce a comprehensive context classification based on a sample scenario to demonstrate how the context of photos and their relationships can be integrated to assist with scenario-based design. An efficient scenario-building technique for concept development and design leads to a simple user-modeling framework whereby the Mobile AP II system can learn to display query results based on photo relationships provided by the designer. The resulting retrieval, browsing and visualization can adapt to the user's selection of content, context and preferences in style and interactive navigation. Our purpose is to develop rich and flexible methods and concepts that can incorporate users' descriptions and their current and potential use of a scenario into the very design reasoning about such a system.

Authors: Li Yujie, Wang Wenguang, Sun Jinping
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 02 (2009)

In this paper, based on the prior knowledge of chaotic character of sea clutter, we discuss a method for detection of small target in sea clutter using neural network as a predictor. Neural network can capture the dynamics of strange attractor generating sea clutter. After the reconstruction of real-life Radar data, BP and RBF networks are regularized, and then a set of sample data from real-life data is inputted into the networks to train the neural networks respectively. As a sequence, according the nature of neural networks, these trained networks could approximate the model of dynamical system responsible for sea clutter. These networks can be used to detect small target within sea clutter as a predictor.

Venue: Proceedings of the 12th Conference of the European Chapter of the Association for Computational Linguistics (2009)

We investigate linguistic features that correlate with the readability of texts for adults with intellectual disabilities (ID). Based on a corpus of texts (including some experimentally measured for comprehension by adults with ID), we analyze the significance of novel discourse-level features related to the cognitive factors underlying our users' literacy challenges. We develop and evaluate a tool for automatically rating the readability of texts for these users. Our experiments show that our discourse-level, cognitively-motivated features improve automatic readability assessment.

Authors: Eleni Kosta, Christos Kalloniatis, Lilian Mitrou, Evangelia Kavakli
Venue: Proceedings of the 6th International Conference on Trust, Privacy and Security in Digital Business (2009)

Nowadays, Internet users are depending on various search engines in order to be able to find requested information on the Web. Although most users feel that they are and remain anonymous when they place their search queries, reality proves otherwise. The increasing importance of search engines for the location of the desired information on the Internet usually leads to considerable inroads into the privacy of users. The scope of this paper is to study the main privacy issues with regard to search engines, such as the anonymisation of search logs and their retention period, and to examine the applicability of the European data protection legislation to non-EU search engine providers. Ixquick, a privacy-friendly meta search engine will be presented as an alternative to privacy intrusive existing practices of search engines.
