Broken Rotor Bar Detection in Induction Motors via Wavelet Ridge
Authors: Yunbing Wei, Baoshan Shi, Guangzhao Cui, Jun Yin
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 02 (2009)

On-line diagnostics of induction motor faults such as broken rotor bars can be accomplished by analyzing the anomalies of motor stator current. This paper presents a novel approach for the detection of the broken rotor bars in induction motors based on wavelet ridge. The characteristic frequency component(CFC) of the broken rotor bars is very close to power frequency in frequency domain but far less in amplitude in steady state, so it is very difficult to detect the broken rotor bars by Fourier Transform. As the CFC of the broken rotor bars approaches power frequency gradually during the motor’s startup process, the wavelet ridge-based method is introduced to analyze this transient procedure and the CFC of the broken rotor bars is extracted effectively. The influence of power frequency can be well eliminated, and the detection accuracy is greatly improved. Experimental results also demonstrate this is truly an excellent approach for the detection of the broken rotor bars.
Using Pictographic Representation, Syntactic Information and Gestures in Text Entry
Authors: Hamed H. Sad, Franck Poirier
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part II: Novel Interaction Methods and Techniques (2009)

With the increasing popularity of touch screen mobile devices, it is becoming increasingly important to design fast and reliable methods for text input on such devices. In this work, we exploit the capabilities of those devices and a specific language model to enhance the efficiency of text entry tasks. We will distribute the roles between the user and the device in a way that allocates the tasks to the side where they can be efficiently done. The user is not a good processor of syntactic and memory retrieval operations but she/he is a highly efficient processor for handling semantic and pattern recognition operations. The reverse is true for computational devices. These facts are exploited in two designs for the entry of common words which represent a high percentage of our written and spoken materials. A common word is typed in two or three clicks, with or without a gesture on a touch screen.

Authors: Rong Liu, Yufeng Zhu, Yan Luo, Xiangtong Liu
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 01 (2009)

Modern urban infrastructure needs a comprehensive and integrated information science and technology. Global Position System (GPS), Geographic Information System (GIS), Digital Photogrammetry and Remote Sensing (RS) and other spatial information technologies are it's core techniques. Products of digital photogrammetry and remote sensing are its basic information resource. The key tasks of modern urban infrastructure are urban planning and management, city modeling and constructing digital city. Urban planners and administrators use UGIS and RS Technologies both as a spatial database and an analysis and modeling tool. This paper presents the use of UGIS in the urban planning and management, and the application of 4D and relevant technologies for modern urban infrastructure. Firstly, the contents of modern urban infrastructure are introduced. Some advanced technologies such as 3D city model and cybercity with virtual reality (VR) environment for UGIS are outlined. Secondly, traditional urban planning and management bases on 2D. Problems during the existing planning process arise because of lack of 3D functionalities to analyze and visualize the 2D/3D data. However, 4D techniques are information of resources of creating and analyzing 3D city model. Three dimensional digital urban model and cybercity constructed using DEM, DOM and associate techniques are present. Thirdly, an example of application of integration of UGIS and digital photogrammetry and remote sensing in urban transportation is explored. Finally, some conclusions are made.
A general expression of the fundamental matrix for both perspective and affine cameras
Authors: Zhengyou Zhang, Gang Xu
Venue: Proceedings of the Fifteenth international joint conference on Artifical intelligence - Volume 2 (1997)

This paper addresses the recovery of structure and motion from two uncalibrated images of a scene under full perspective or under affine projection. Epipolar geometry, projective reconstruction, and affine reconstruction are elaborated in a way such that everyone having knowledge of linear algebra can understand the discussion without difficulty. A general expression of the fundamental matrix is derived which is valid for any projection model without lens distortion (including full perspective and affine camera). A new technique for affine reconstruction from two affine images is developed, which consists in first estimating the affine epipolar geometry and then performing a triangulation for each point match with respect to an implicit common affine basis. This technique is very efficient.

Authors: Joseph A. Giampapa, Katia P. Sycara, Gita Sukthankar
Venue: Proceedings of the 1st International Working Conference on Human Factors and Computational Models in Negotiation (2008)

This article reports work on first steps toward characterizing a negotiation process model for ad hoc and distributed groups or teams, so that automation can more accurately track the states of a negotiation from human discourse. We devised three experimental scenarios and ran human subject experiments that involved group decision-making and consensus building. Our experiments showed that the communication patterns of successful distributed ad hoc teams differed in two significantly different conditions. We describe our motivations, experimental design and results.
The Design of a Miniature Autonomous Surveillance Robot
Authors: Change Zheng
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

Secret surveillance in tightly constrained spaces is demanded in many military and civilian activities, such as cave-in enemy raids and indoor hostage rescue missions. These special applications require a kind of miniature mobile robot to function covertly in highly confined environments. However, the crucial problem resulted from the small volume of miniature robots is the difficulty of packing locomotion, sensing, computing and power subsystems into constrained space. This paper presents the mechanical design including a kind of miniature flexible driving mechanism, and the control system of a miniature autonomous surveillance robot for indoor reconnaissance tasks. Several experiments showed that this robot was useful for covert surveillance in confined spaces and can carry out reconnaissance missions on its own or by teleoperation.
Semiotic Analysis of Electronic Mathematical Texts: Semiotics of Web Based Mathematics
Authors: Wajeeh Daher
Venue:  (2009)

This dissertation comes to answer an increasing need for an analysis tool that enables to analyze and evaluate electronic mathematical texts which populate the internet and serve the mathematics teacher as additional texts for school students. These texts are web based and include dynamic components which the user can work with, in order to learn mathematics. The dissertation contains two parts: the first part provides an analyzing system for electronic mathematical texts. This analyzing system was founded on Morris's (1938) formal semiotics and Halliday's (1985) and Morgan's (1998) social semiotics. The second part of the dissertation describes preservice teachers' work with the semiotic system for analyzing and evaluating electronic mathematical texts, their opinions of this system, and their arguments with or against the utility and importance of the various aspects of the semiotic system. To analyze the preservice arguments, Toulmin's argumentation model was used. This model describes arguments in terms of grounds, qualifiers, claims, warrants, rebuttals, and backings, so the model enables to analyze deeply the structure and meanings of the arguments.

A Parallel Simulator for Mercury (Hg) Porosimetry
Authors: C. H. Moreno-Montiel, F. Rojas-González, G. Román-Alonso, S. Cordero-Sánchez, M. A. Castro-García, M. Aguilar-Cornejo
Venue: Proceedings of the 16th European PVM/MPI Users' Group Meeting on Recent Advances in Parallel Virtual Machine and Message Passing Interface (2009)

A parallel simulator, based on the Dual Site-Bond Model of complex media, is developed to study Hg intrusion and extrusion processes in the myriad of voids contained in a porous network. In order to reduce the requirements in RAM and computing resources, the porous network is partitioned into several sub-networks distributed in different cluster processors. The simulator uses shared memory to process (with OpenMP) each sub-network and applies a message passing protocol (with MPI) to allow communication among different processors. We show experimental results that reflect a good performance of our proposal when using different sizes of porous networks in a cluster with 32 nodes, each one having 4 processors.

Authors: Tomoyuki Watanabe, Masako Omori, Satoshi Hasegawa, Shohei Matsunuma, Masaru Miyao
Venue: Proceedings of the Symposium on Human Interface 2009 on Human Interface and the Management of Information. Information and Interaction. Part II: Held as part of HCI International 2009 (2009)

Textual information can be sent as graphic images without being coded in the broadband digital network. By using graphic text, characters or symbols with unsupported fonts can be displayed. Graphical e-mail systems in mobile phones for sending digital photographs are useful in sending graphic text. We researched the visibility of graphic text on the liquid crystal displays in mobile phones comparing with that of font in the mobile phones, by measuring the variables of reading time and visual distance. We also recorded the number of errors, and subjects evaluated the visibility. Graphic text prepared in the JPEG format had nearly the same visibility of the original font. However, it must be noted that visibility deteriorates as the character size become smaller, and as the user become older. We also mention about the possibility of multilingual disaster information system with mobile phones as an application of the graphic text. Graphic text enables easy display of multilingual information by ordinary types of mobile phones which does not support multilingual characters.
Modelling and Implementing Irrational and Subconscious Interpersonal and Intra-personal Processes
Authors: Andrew Nicolson
Venue: Proceedings of the 9th International Conference on Intelligent Virtual Agents (2009)

Although there is progress in modeling and implementing affective phenomena --- computation of emotion --- the new direction proposed here is to model and represent irrational and subconscious processes, the hidden aspects of the human psyche as analysed by Freud and his successors, and by other disciplines in psychotherapy.The outcome will be a `psychodynamics engine' that does not simply respond emotionally to context and interaction, but is driven by its own convoluted patterns, triggers and processes. This can potentially be used in an affective architecture for games, companioniable robotics, online virtual entities etc., interacting with humans.

Authors: P. P. Zhu, J. G. Liu, S. K. Dai, G. Y. Wang
Venue: EURASIP Journal on Advances in Signal Processing (2009)

An efficient algorithm derived from AAN algorithm (proposed by Arai, Agui, and Nakajima in 1988) for computing the Inverse Discrete Cosine Transform (IDCT) is presented. We replace the multiplications in conventional AAN algorithm with additions and shifts to realize the fixed-point and multiplier-free computation of IDCT and adopt coefficient and compensation matrices to improve the precision of the algorithm. Our 1D IDCT can be implemented by 46 additions and 20 shifts. Due to the absence of the multiplications, this modified algorithm takes less time than the conventional AAN algorithm. The algorithm has low drift in decoding due to the higher computational precision, which fully complies with IEEE 1180 and ISO/IEC 23002-1 specifications. The implementation of the novel fast algorithm for 32-bit hardware is discussed, and the implementations for 24-bit and 16-bit hardware are also introduced, which are more suitable for mobile communication devices.

Query-URL bipartite based approach to personalized query recommendation
Authors: Lin Li, Zhenglu Yang, Ling Liu, Masaru Kitsuregawa
Venue: Proceedings of the 23rd national conference on Artificial intelligence - Volume 2 (2008)

Query recommendation is considered an effective assistant in enhancing keyword based queries in search engines and Web search software. Conventional approach to query recommendation has been focused on query-term based analysis over the user access logs. In this paper, we argue that utilizing the connectivity of a query-URL bipartite graph to recommend relevant queries can significantly improve the accuracy and effectiveness of the conventional query-term based query recommendation systems. We refer to the Query-URL Bipartite based query reCommendation approach as QUBIC. The QUBIC approach has two unique characteristics. First, instead of operating on the original bipartite graph directly using biclique based approach or graph clustering, we extract an affinity graph of queries from the initial query-URL bipartite graph. The affinity graph consists of only queries as its vertices and its edges are weighted according to a query-URL vector based similarity (distance) measure. By utilizing the query affinity graph, we are able to capture the propagation of similarity from query to query by inducing an implicit topical relatedness between queries. We devise a novel rank mechanism for ordering the related queries based on the merging distances of a hierarchical agglomerative clustering. We compare our proposed ranking algorithm with both naïve ranking that uses the query-URL similarity measure directly, and the single-linkage based ranking method. In addition, we make it possible for users to interactively participate in the query recommendation process, to bridge the gap between the determinacy of actual similarity values and the indeterminacy of users' information needs, allowing the lists of related queries to be changed from user to user and query to query, thus personalizing the query recommendation on demand. The experimental results from two query collections demonstrate the effectiveness and feasibility of our approach.
View Planning for 3D Reconstruction Using Time-of-Flight Camera Data
Authors: Christoph Munkelt, Michael Trummer, Peter Kühmstedt, Gunther Notni, Joachim Denzler
Venue: Proceedings of the 31st DAGM Symposium on Pattern Recognition (2009)

Solving the next best view (NBV) problem is an important task for automated 3D reconstruction. An NBV algorithm provides sensor positions, from which maximal information gain about the measurement object during the next scan can be expected. With no or limited information available during the first views, automatic data driven view planning performs suboptimal. In order to overcome these inefficiencies during startup phase, we examined the use of time-of-flight (TOF) camera data to improve view planning. The additional low resolution 3D information, gathered during sensor movement, allows to plan even the first scans customized to previously unknown objects. Measurement examples using a robot mounted fringe projection stereo 3D scanner with a TOF camera are presented.
Branching Bisimilarity with Explicit Divergence
Authors: Rob van Glabbeek, Bas Luttik, Nikola Trčka
Venue: Fundamenta Informaticae (2009)

We consider the relational characterisation of branching bisimilarity with explicit divergence. We prove that it is an equivalence and that it coincides with the original definition of branching bisimilarity with explicit divergence in terms of coloured traces. We also establish a correspondence with several variants of an action-based modal logic with until- and divergence modalities.
Application of Dynamic Route Selection Model in Urban Transportation Distribution
Authors: Xiao-lan Liu, Wei Cheng
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 03 (2009)

Based on studies and analysis of route selection model, modified road network model is brought forward by taking account of the particularity of route. And not like traditional methods using many virtual links and nodes to express every turning in intersections, modified road network shows them as road network data. Because only accessibility in traffic behavior can meet demand of route optimization, to achieve better efficiency enhancement, the solution that road network data and topological structure are separated in physics and combined in logic is proposed. Corresponding expressive way is given for different categories of nodes in modified road network model and double-layer road networks are used if it’s a large network. Finally, a thought that penalty value could be used to prevent Braess phenomenon is put forward. Moreover, a test is also done to a little road network by using multi-Router algorithm and an optimization route is found out.
TAROT: trajectory-assisted routing for intermittently connected networks
Authors: Matthew K. Bromage, James T. Koshimoto, Katia Obraczka
Venue: Proceedings of the 4th ACM workshop on Challenged networks (2009)

We introduce TAROT (Trajectory-Assisted ROuTing), a DTN routing framework that detects and extracts structure in node movement in real-time. TAROT is motivated by the postulate that mobility, in particular human mobility such as vehicles, is seldom random and thus exhibits recognizable patterns. TAROT's mobility pattern extraction capabilities transcends current solutions that rely on abbreviated (in some cases, instantaneous) snapshots of mobility history. TAROT is therefore able to predict future mobility with increased accuracy. Routing decisions are guided by node mobility patterns, ultimately resulting in more efficient routing and forwarding of messages. Our approach is capable of accommodating conditions where the best node may be one that is currently moving away from the destination. In its current implementation, TAROT uses a "controlled epidemic" approach to route messages in which nodes will only be "infected" with a message if their mobility pattern takes them closer to the destination. We evaluate TAROT's performance through simulations using the QualNet network simulator. A side-by-side comparison against Epidemic Routing under a variety of mobility and workload scenarios show that TAROT is able to match Epidemic's high data delivery guarantees at substantially reduced overhead (over 60% in some of our experiments). TAROT's efficiency comes at the price of a slight increase in delivery delay (around 20% in our experiments). We argue that applications that use intermittently-connected networked environments are inherently tolerant of delay, and therefore favor slight increases in delay for increased efficiency and reduced resource consumption.
Leaf Menus: Linear Menus with Stroke Shortcuts for Small Handheld Devices
Authors: Anne Roudaut, Gilles Bailly, Eric Lecolinet, Laurence Nigay
Venue: Proceedings of the 12th IFIP TC 13 International Conference on Human-Computer Interaction: Part I (2009)

This paper presents Leaf menu, a new type of contextual linear menu that supports curved gesture shortcuts. By providing an alternative to keyboard shortcuts, the Leaf menus can be used for the selection of commands on tabletops, but its key benefit is its adequacy to small handheld touchscreen devices (PDA, Smartphone). Indeed Leaf menus define a compact and known layout inherited from linear menus, they support precise finger interaction, they manage occlusion and they can be used in close proximity to the screen borders. Moreover, by providing stroke shortcuts, they favour the selection of frequent commands in expert mode and make eye-free selection possible.
Theory and Applications of Computational Chemistry - 2008, 1st edition
Authors: Dong-Qing Wei, Xi-Jun Wang
Venue:  (2009)

The TACC conference deals with the theoretical methods and application of computational chemistry. The theoretical aspects include development of computational and statistical techniques, quantum and statistical mechanical methods that could be used to solve complicated scientific problems, which will be applied to various fields of chemistry, physics and biology. Since the first applications of computer in chemistry in the early 1960s, computational chemistry has evolved today to be at the vanguard of most advances in chemistry, material science, physics, geology, biology and medicine. Its impact on chemistry can be noted from the fact that within four decades of its existence, five of the top ten most highly cited publications in 125 years of JACS are related to computational chemistry. Apart from technical advances in computers and algorithms, the phenomenal impact of computational chemistry is also due to the dedicated and sustained efforts of a large number of individuals who participated in this most important conference in this field.
