3D Neural Model-Based Stopped Object Detection
Authors: Lucia Maddalena, Alfredo Petrosino
Venue: Proceedings of the 15th International Conference on Image Analysis and Processing (2009)

In this paper we propose a system that is able to distinguish moving and stopped objects in digital image sequences taken from stationary cameras. Our approach is based on self organization through artificial neural networks to construct a model of the scene background and a model of the scene foreground that can handle scenes containing moving backgrounds or gradual illumination variations, helping in distinguishing between moving and stopped foreground regions, leading to an initial segmentation of scene objects. Experimental results are presented for video sequences that represent typical situations critical for detecting vehicles stopped in no parking areas and compared with those obtained by other existing approaches.

Authors: Zechao Tan, Jie Yang, Zifeng Shang, Guangshun Shi, Shengjiang Chang
Venue: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 04 (2009)

As a noteworthy biometric technology, offline palmprint identification plays a very important role in the application of social security. Given a palmprint scanned by a digital instrument, offline palmprint identification needs to perform robust feature matching because of the rotation and distortion existed in input. In our paper we design and implement aminutiae-based offline palmprint identification system, which can realize the unrestricted matching between the complete palmprint and misshapen palmprint, therefore being able to identify of the owner of the palmprint. The paper presents the location, image enhancement, thinning, minutia feature extraction and feature matching in detail. The system framework and processing approach can overcome various issues caused by the limitation of condition in palmprint acquisition and achieve stable results. The experiment based on the true date test proves the effictiveness and efficiency of the work in this article.
Job Security
Authors: Diomidis Spinellis
Venue: IEEE Software (2009)

Some consider unmaintainable code a tool that provides job security. At the low level, you can obtain such code through incorrect or inconsistent formatting, naming, and commenting. Complex and gratuitous coupling, lack of assertions, and failure to use a language's type system can further complicate the picture. At a higher level, deep and wide class hierarchies, lack of cohesion, and unhelpful package relationships can hinder maintainability. Finally, at the development process level, lack of version control, subpar build-and-release procedures, a lacking testing infrastructure, and the hiring of mediocre developers will hammer the last nails into a project's maintainability coffin.

Authors: Deepti Mishra, Alok Mishra
Venue: Human Factors in Ergonomics Manufacturing (2009)

Effective communication, collaboration, and coordination are important contributing factors in achieving success in agile software development projects. The significance of the workplace environment and tools are immense in effective communication, collaboration, and coordination among people performing software development. In this article, we study how the workplace environment and the effective use of tools like whiteboards, status boards, and so forth for exchanging information improved communication, collaboration, and coordination without compromising the ability to do individual work by developers in a small-scale software development organization. Based on experience and an extensive literature review of communication, collaboration, coordination, and the significance of these in the workplace environment, a survey questionnaire was developed to collect data and observe the effect of these in a small software development organization. Our study indicated appropriate workspace environment has a positive effect on communication, collaboration, and coordination in small organizations developing software using eXtreme Programming (XP). &copy; 2009 Wiley Periodicals, Inc.

Authors: Caihong Yang, Fei Wang, Benxiong Huang
Venue: Proceedings of the 2009 WASE International Conference on Information Engineering - Volume 02 (2009)

In recent years, a technique based on machinelearning for Internet traffic classification has attracted more and more attentions. It not only overcomes some shortcomingsof traditional classification technique based on port number,but also does not inspect the packet payload, which involves the security and privacy. In this paper, we apply an unsupervised machine learning approach based on DBSCANalgorithm. DBSCAN algorithm has three merits: (1) minimalrequirements of domain knowledge to determine the inputparameters; (2) discovery of clusters with arbitrary shapes; (3)good efficiency on large data set. Experiment results show that DBSCAN has better effectiveness and efficiency.

Authors: Bingqiang Yu, Hongmin Liu, Lipo Yang, Yan Peng, Zhiming Li
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 02 (2009)

A contact shape meter with new structure, called MPIBPST(Multi-Roll-Piece Inner Bore Piezomagnetic Sensor Type) shape meter, for cold-rolled steel strip is developed, and it is applied to 1050II HC mill. Optimization design on the structure of shape meter roll is carried out and shape signal is compensated properly from several perspectives, for example, shape meter roll deflection, strip temperature and amplitude-frequency characteristic, etc. The application result shows that the MPIBPST shape meter has the advantages of rational structure, stronger anti-interference ability, signal stability and credibility, high-precision and a long service life.
An Embodied Approach for Engaged Interaction in Ubiquitous Computing
Authors: Mark O. Millard, Firat Soylu
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part III: Ubiquitous and Intelligent Interaction (2009)

A particular vision of ubiquitous computing is offered to contribute to the burgeoning, dominant interaction paradigm in human-computer interaction (HCI). An engaged vision of ubiquitous computing (UbiComp) can take advantage of natural human abilities and tendencies for interaction. The HCI literature is reviewed to provide a brief overview of promising interaction styles and paradigms in order to situate them within ubiquitous computing. Embodied interaction is introduced as a key theoretical framework for moving UbiComp forward as an engaged interaction paradigm.
A Complexity Dichotomy for Finding Disjoint Solutions of Vertex Deletion Problems
Authors: Michael R. Fellows, Jiong Guo, Hannes Moser, Rolf Niedermeier
Venue: Proceedings of the 34th International Symposium on Mathematical Foundations of Computer Science 2009 (2009)

We investigate the computational complexity of a general "compression task" centrally occurring in the recently developed technique of iterative compression for exactly solving NP-hard minimization problems. The core issue (particularly but not only motivated by iterative compression) is to determine the computational complexity of, given an already inclusion-minimal solution for an underlying (typically NP-hard) vertex deletion problem in graphs, to find a better disjoint solution. The complexity of this task is so far lacking a systematic study. We consider a large class of vertex deletion problems on undirected graphs and show that, except for few cases which are polynomial-time solvable, the others are NP-complete. This class includes problems such as Vertex Cover (here the corresponding compression task is decidable in polynomial time) or Undirected Feedback Vertex Set (here the corresponding compression task is NP-complete).
Surface Quasi-Conformal Mapping by Solving Beltrami Equations
Authors: W. Zeng, F. Luo, S. -T. Yau, X. D. Gu
Venue: Proceedings of the 13th IMA International Conference on Mathematics of Surfaces XIII (2009)

We consider the problem of constructing quasi-conformal mappings between surfaces by solving Beltrami equations. This is of great importance for shape registration.In the physical world, most surface deformations can be rigorously modeled as quasi-conformal maps. The local deformation is characterized by a complex-value function, Beltrami coefficient, which describes the deviation from conformality of the deformation at each point.We propose an effective algorithm to solve the quasi-conformal map from the Beltrami coefficient. The major strategy is to deform the conformal structure of the original surface to a new conformal structure by the Beltrami coefficient, such that the quasi-conformal map becomes a conformal map. By using holomorphic differential forms, conformal maps under the new conformal structure are calculated, which are the desired quasi-conformal maps.The efficiency and efficacy of the algorithms are demonstrated by experimental results. Furthermore, the algorithms are robust for surfaces scanned from real life, and general for surfaces with different topologies.

Representation and treatment of multiword expressions in Basque
Authors: Iñaki Alegria, Olatz Ansa, Xabier Artola, Nerea Ezeiza, Koldo Gojenola, Ruben Urizar
Venue: Proceedings of the Workshop on Multiword Expressions: Integrating Processing (2004)

This paper describes the representation of Basque Multiword Lexical Units and the automatic processing of Multiword Expressions. After discussing and stating which kind of multiword expressions we consider to be processed at the current stage of the work, we present the representation schema of the corresponding lexical units in a general-purpose lexical database. Due to its expressive power, the schema can deal not only with fixed expressions but also with morphosyntactically flexible constructions. It also allows us to lemmatize word combinations as a unit and yet to parse the components individually if necessary. Moreover, we describe HABIL, a tool for the automatic processing of these expressions, and we give some evaluation results. This work must be placed in a general framework of written Basque processing tools, which currently ranges from the tokenization and segmentation of single words up to the syntactic tagging of general texts.
The ANGEL WSN Security Architecture
Authors: Oscar Garcia-Morchon, Heribert Baldus
Venue: Proceedings of the 2009 Third International Conference on Sensor Technologies and Applications (2009)

The EU funded ANGEL project focuses on the development and deployment of wireless sensor networks building ambient intelligence systems for assisted-living and personal health monitoring. The provision of security services such as confidentiality and authentication is a fundamental requirement for ANGEL in order to ensure the safety and privacy of the users; the technical realization is challenging due to the high mobility of users accessing a multitude of wireless sensor networks. Our security architecture ensures the secure deployment and efficient, yet secure operation of ANGEL systems. Based on keying-material distribution, we provide a solution for the secure configuration of sensors and gateways. This ensures that users can interact with their system in an easy, transparent and safe way. We further introduce a fast distributed key agreement protocol on top of ZigBee that enables very fast and efficient operation. Performance and security analysis point out the advantages of our new solution.
A Security Pattern for Untraceable Secret Handshakes
Authors: Angel Cuevas, Paul El Khoury, Laurent Gomez, Annett Laube, Alessandro Sorniotti
Venue: Proceedings of the 2009 Third International Conference on Emerging Security Information, Systems and Technologies (2009)

A security pattern describes a particular recurring security problem that arises in specific contexts and presents a well-proven generic solution for it. This paper describes an Untraceable Secret Handshake, a protocol that allows two users to mutually verify another’s properties without revealing their identity. The complex security solution is split into smaller parts which are described in an abstract way. The identified security problems and their solutions are captured as SERENITY security patterns. The structured description together with motivating scenarios makes the security solution better understandable for non-security experts and helps to disseminate the security knowledge to application developers.
Ludics with Repetitions (Exponentials, Interactive Types and Completeness)
Authors: Michele Basaldella, Claudia Faggian
Venue: Proceedings of the 2009 24th Annual IEEE Symposium on Logic In Computer Science (2009)

We prove that is possible to extend Girard's Ludics so as to have repetitions (hence exponentials), and still have the results on semantical types which characterize Ludics in the panorama of Game Semantics. The results are obtained by using less structure than in the original paper; this has an interest on its own, and we hope that it will open the way to applying the approach of Ludics to a larger domain.
Recognizing threat: A simple geometric shape activates neural circuitry for threat detection
Authors: Christine L. Larson, Joel Aronoff, Issidoros C. Sarinopoulos, David C. Zhu
Venue: Journal of Cognitive Neuroscience (2009)

The urgent need to recognize danger quickly has been shown to rely on preferential processing in dedicated neural circuitry. In previous behavioral studies examining the pattern of the face when displaying anger, we found evidence that simple noncontextual geometric shapes containing downward-pointing V-shaped angles activate the perception of threat. We here report that the neural circuitry known to be mobilized by many realistic, contextual threatening displays is also triggered by the simplest form of this V-shaped movement pattern, a downward-pointing triangle. Specifically, we show that simple geometric forms containing only downward-pointing V-shapes elicit greater activation of the amygdala, subgenual anterior cingulate cortex, superior temporal gyrus, and fusiform gyrus, as well as extrastriate visual regions, than do presentations of the identical V-shape pointing upward. Thus, this simple V-shape is capable of activating neural networks instantiating detection of threat and negative affect, suggesting that recognition of potential danger may be based, in part, on very simple, context-free visual cues.

Authors: Han Kai, Xu Hongrui
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 01 (2009)

Power line inspection is an important aspect of electrical production safety. In view of the current power line inspection system with low positioning accuracy, big human factors and high cost, by using wireless sensor networks (WSN) and WiFi technology, this paper proposed a new power line inspection solution. The power line inspection system is divided into tower/power line information collection system, handheld device and central station management information system (MIS). Information collection system collects information by various sensor nodes and sends it to data gathering node by WSN, the data gathering node uses WiFi to send information to handheld device, and handheld device send information to central station MIS. Finally, combined with wireless network, we discussed the prospect of using wireless network in power line inspection and the difficulties which should be overcome.

Authors: Bingli Zhao, Yuanyu Cao, Zhongbao Li, Jin Chen, Guiling Zhang, Guanggao Lei, Zhanlin Wang
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 02 (2009)

Genetic diversity and differentiation were investigated using assay of vertical slab ployacrylamide gel electrophoresis for the nine populations of Marsupenaeus japonicus. The results showed high levels of genetic diversity in each of the nine M. japonicus populations. The mean number of alleles per locus ranged from 1.0000 to 1.0152, with a average of 1.0017, and the mean effective number of alleles per locus ranged from 1.1137 to 1.2012, with a average of 1.1463. the average of percentage of polymorphic loci was 18.18%, ranging from 13.64% to 22.73%, the average of observed heterozygosity was 0.0907, ranging from 0.0742 to 0.1121 and the average of expected heterozygosity was 0.0714, ranging from 0.0573 to 0.0930. The coefficient of gene differentiation among populations is low (0.0432), indicating that only 4.32% of the total genetic diversity comes from inter-population, while the remaining 95.68% comes from intra-population differences. The genetic distance among populations is 0.0002～0.0123 and gene flow among the populations is large (5.5406). The results suggest that genetic structure is very similar among the nine M. japonicus populations studied.

Authors: Yanwei Xu, Yoshiharu Ishikawa, Jihong Guan
Venue: Advances in Web and Network Technologies, and Information Management: APWeb/WAIM 2009 International Workshops: WCMT 2009, RTBI 2009, DBIR-ENQOIR 2009, PAIS 2009, Suzhou, China, April 2-4, 2009, Revised Selected Papers (2009)

Keyword search in relational databases has recently emerged as a new research topic. As a search result is often assembled from multiple relational tables, existing IR-style ranking strategies can not be applied directly. In this paper, we propose a novel IR ranking strategy considering query semantics for effective keyword search. The experimental results on a large-scale real database demonstrate that our method results in significant improvement in terms of retrieval effectiveness as compared to previous ranking strategies.

Rank/select on dynamic compressed sequences and applications
Authors: Rodrigo González, Gonzalo Navarro
Venue: Theoretical Computer Science (2009)

Operations rank and select over a sequence of symbols have many applications to the design of succinct and compressed data structures managing text collections, structured text, binary relations, trees, graphs, and so on. We are interested in the case where the collections can be updated via insertions and deletions of symbols. Two current solutions stand out as the best in the tradeoff of space versus time (when considering all the operations). One solution, by Makinen and Navarro, achieves compressed space (i.e., nH"0+o(nlog@s) bits) and O(lognlog@s) worst-case time for all the operations, where n is the sequence length, @s is the alphabet size, and H"0 is the zero-order entropy of the sequence. The other solution, by Lee and Park, achieves O(logn(1+log@sloglogn)) amortized time and uncompressed space, i.e. nlog"2@s+O(n)+o(nlog@s) bits. In this paper we show that the best of both worlds can be achieved. We combine the solutions to obtain nH"0+o(nlog@s) bits of space and O(logn(1+log@sloglogn)) worst-case time for all the operations. Apart from the best current solution to the problem, we obtain several byproducts of independent interest applicable to partial sums, text indexes, suffix arrays, the Burrows-Wheeler transform, and others.
A Study of Fire Information Detection on PDA Device
Authors: Xianghong Sun, Weina Qu, Thomas Plocher, Li Wang
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part III: Ubiquitous and Intelligent Interaction (2009)

This study was concentrated on how useful the en route information display system for firefighters' information accessing, current situation understanding, and decision making, we did a series of tests to investigate the efficiency of the system, to compare different display ways including audio, text, and their combinations to find the most appropriate one. The result showed that: (1) Audio only always made firefighter taking the longest time to information detection, but the introduction of audio display made the two combined displays (text + audio, and text + 3rd level audio) more quickly to access information, and more easy to remember. (2) It should be clarified that en route system could be used very well either in quiet and static environment, or in a moving and a little bumping environment if user could get some training before using it.
Trust Based Authorization and Access Control
Authors: Feng Fujun, Li Junshan
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 03 (2009)

Authorization is very important for access control, which can prevent the illegal operations of users and protect the system security. We firstly introduce a Trust and Context based Access Control (TCAC) model. Then we apply TCAC to the national College Entrance System (CES), and express the basic elements of TCAC in CES. Finally, we discuss the authorization rules of different subjects with different roles. An algorithm is proposed to detect conflict rules. Moreover, we prove the completeness of these authorization rules.
Structured annotations for 2D-to-3D modeling
Authors: Yotam Gingold, Takeo Igarashi, Denis Zorin
Venue: ACM Transactions on Graphics (TOG) (2009)

We present a system for 3D modeling of free-form surfaces from 2D sketches. Our system frees users to create 2D sketches from arbitrary angles using their preferred tool, which may include pencil and paper. A 3D model is created by placing primitives and annotations on the 2D image. Our primitives are based on commonly used sketching conventions and allow users to maintain a single view of the model. This eliminates the frequent view changes inherent to existing 3D modeling tools, both traditional and sketch-based, and enables users to match input to the 2D guide image. Our annotations---same-lengths and angles, alignment, mirror symmetry, and connection curves---allow the user to communicate higher-level semantic information; through them our system builds a consistent model even in cases where the original image is inconsistent. We present the results of a user study comparing our approach to a conventional "sketch-rotate-sketch" workflow.
