Tracking in Distributed Multisensor System Update with Out-of-Sequence Information
Authors: Jin Xue-bo, Wang Lei-lei
Venue: Proceedings of the 2009 International Conference on Computational Intelligence and Natural Computing - Volume 01 (2009)

In multisensor target tracking systems measurements from the same target can arrive out of sequence. How to fuse out-of-sequence information is a very important problem for distributed multisensor target tracking systems. Local sensors send their track to a fusion center and then the fusing center uses these track data from one or more sensors to update. In this paper, we obtain the out-of-sequence track in fusion center for distributed multisensor system based on the assumption that each sensor transmits to the central tracker only the last updated state for each track and the corresponding covariance matrix. Then we present numerical results using simulated data for a scenario where a global tracker processes track data from two local trackers. The results show the distributed fusion here is perfectly compared with the out-of-sequence measurement method.

Laterally connected lobe component analysis: Precision and topography
Authors: Matthew D. Luciw, Juyang Weng
Venue: Proceedings of the 2009 IEEE 8th International Conference on Development and Learning (2009)

Due to the pressure of evolution, the brains of organisms need to self-organize at different scales during different developmental stages. In early stages, the brain must organize globally (e.g., large cortical areas) to form “smooth” topographic representation that is critical for superior generalization with its limited connections. At later stages, the brain must fine tune its microstructures of representation for “precision” - high-level performance and specialization. But smoothness and precision are two conflicting criteria. The self-organizing map (SOM) mechanisms of self-organization through isotropic updating and other published computational variants have dealt with global to local smoothing and lateral adaptation, but we show in our work that they are insufficient to deliver superior performance. In this paper, we introduce a combination of several mechanisms that, together, address these two conflicting criteria: lateral excitation through adaptive connections, explicit adaptive top-down connections (attention), dually-optimal lobe component analysis (LCA) for synaptic updating, simulated lateral inhibition through winners-take-all, and a developmental schedule that sets the number of winners, which decreases over time. Major performance improvements due to the combination of these mechanisms are shown in the reported experiments.
The XMLBench Project: Comparison of Fast, Multi-platform XML libraries
Authors: Suren Chilingaryan
Venue: Database Systems for Advanced Applications: DASFAA 2009 International Workshops: BenchmarX, MCIS, WDPP, PPDA, MBC, PhD, Brisbane, Australia, April 20 - 23, 2009 (2009)

The XML technologies have brought a lot of new ideas and abilities in the field of information management systems. Nowadays, XML is used almost everywhere: from small configuration files to multi-gigabyte archives of measurements. Many network services are using XML as transport protocol. XML based applications are utilizing multiple XML technologies to simplify software development: DOM is used to create and navigate XML documents, XSD schema is used to check consistency and validity, XSL simplifies transformation between different formats, XML Encryption and Signature establishes secure and trustworthy way of information exchange and storage. These technologies are provided by multiple commercial and open source libraries which are significantly varied in features and performance. Moreover, some libraries are optimized to certain tasks and, therefore, the actual library performance could significantly vary depending on the type of data processed. XMLBench project was started to provide comprehensive comparison of available XML toolkits in their functionality and ability to sustain required performance. The main target was fast C and C++ libraries able to work on multiple platforms. The applied tests compare different aspects of XML processing and are run on few auto-generated data sets emulating library usage for different tasks.The details of test setup and achieved results will be presented.

Significance-Based Failure and Interference Detection in Data Streams
Authors: Nickolas J. Falkner, Quan Z. Sheng
Venue: Proceedings of the 20th International Conference on Database and Expert Systems Applications (2009)

Detecting the failure of a data stream is relatively easy when the stream is continually full of data. The transfer of large amounts of data allows for the simple detection of interference, whether accidental or malicious. However, during interference, data transmission can become irregular, rather than smooth. When the traffic is intermittent, it is harder to detect when failure has occurred and may lead to an application at the receiving end requesting retransmission or disconnecting. Request retransmission places additional load on a system and disconnection can lead to unnecessary reversion to a checkpointed database, before reconnecting and reissuing the same request or response. In this paper, we model the traffic in data streams as a set of significant events, with an arrival rate distributed with a Poisson distribution. Once an arrival rate has been determined, over-time, or lost, events can be determined with a greater chance of reliability. This model also allows for the alteration of the rate parameter to reflect changes in the system and provides support for multiple levels of data aggregation. One significant benefit of the Poisson-based model is that transmission events can be deliberately manipulated in time to provide a steganographic channel that confirms sender/receiver identity.
Directional Geometric Routing on Mobile Ad Hoc Networks
Authors: Kazushige Sato, Takeshi Tokuyama
Venue: Proceedings of the 15th Annual International Conference on Computing and Combinatorics (2009)

We consider the geometric routing problem on mobile adhoc wireless networks such that we can send packets by only using local information at each node. We design a novel routing algorithm named directional routing algorithm by using random local neighbors such that the information can be efficiently maintained if each node dynamically changes its position. In our scheme, the number of hops and the number of transmissions issued during the routing process are both very small. No centralized control is necessary: The network is implicitly stored and maintained in a distributed fashion at each node using O(1) space, and constructed only using local information in transmission disk of each node. Using this network, we give the first geometric routing with nontrivial theoretical performance gurantee.
Constrained Reachability of Process Rewrite Systems
Authors: Tayssir Touili
Venue: Proceedings of the 6th International Colloquium on Theoretical Aspects of Computing (2009)

We consider the problem of analyzing multi-threaded programs with recursive calls, dynamic creation of parallel procedures, and communication. We model such programs by Process Rewrite Systems (PRS) which are sets of term rewriting rules. Terms in this framework represent program control structures. The semantics of PRS systems is defined modulo structural equivalences on terms expressing properties of the operators appearing in the terms (idle process, sequential composition, and asynchronous parallel composition).We consider the problem of reachability analysis of PRSs under constraints on the execution actions. This problem is undecidable even for regular constraints. [LS98] showed that it becomes decidable for decomposable constraints for the PRS subclass PA if structural equivalences are not taken into account. In this work, we go further and show that for decomposable constraints, we can compute tree automata representations of the constrained reachability sets for the whole class of PRS modulo different structural equivalences. Our results can be used to solve program (data flow) analysis and verification problems that can be reduced to the constrained reachability analysis problem.

A General Geo-spatial Multi-scale Conceptual Model for Automatic Generalization
Authors: Yaoming Yang, Xiaoan Tang, Zhe Gan, Haiyan Jiang
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 02 (2009)

With the development of GIS, it is in great need of integration of multi-source heterogeneous spatial data at different scales. Most of the existing scale generalization algorithms aim at particular types of geo-spatial objects, which are short of versatility. Based on the functional classification and the definition of multi-scale generalization operators, a general multi-scale conceptual model is proposed for various geo-spatial elements, which is expressed in the form of data-operator-relation triple. A corresponding Agent model and a processing flow are also designed for automatic generalization. Through an example, the conceptual model is verified to be adaptive for different kinds of geo-spatial elements. And the Agent-based multi-scale generalization method is effective and fully automatic.
Intelligent output interface for intelligent medical search engine
Authors: Gang Luo
Venue: Proceedings of the 23rd national conference on Artificial intelligence - Volume 2 (2008)

To facilitate ordinary people to search medical information, we have built an intelligent medical Web search engine called iMed. iMed uses medical knowledge and an interactive questionnaire to find multiple diseases serving as queries. The search results of these queries are combined together and returned to the searcher in a traditional sequential order. Nevertheless, searchers still frequently miss desired information, because the traditional search result output interface cannot capture the internal structures of medical search results. This paper presents a new, intelligent search result output interface devoted to intelligent medical search. The new output interface automatically offers searchers what they want instead of waiting until they ask explicitly. It structures all the search results into a multi-level hierarchy with explicitly marked medical meanings. In this way, searchers can efficiently navigate among all the search results and quickly obtain desired information. We demonstrate the effectiveness of our techniques through an evaluation using USMLE medical exam cases.
Considerations for Using Eye Trackers during Usability Studies
Authors: Anjali Phukan, Margaret Re
Venue: Proceedings of the 3rd International Conference on Internationalization, Design and Global Development: Held as Part of HCI International 2009 (2009)

The purpose of this usability study was to see if eye trackers collect valid data, regardless of the user's method of corrected vision, eye color, or gender. The motivation to explore the idea that these human factors can distort eye trackers is based on marketing claims by several companies that say these factors should not affect results. This study found that the validity of data in usability studies that involved eye trackers in testing can produce biased results based on eyewear and eye color, and that adjustments should be made to control for these variables. The results showed no significant correlations based on gender. As a consideration into developing international signage for mass transportation systems that effectively accommodate global users, this study also explored how first language affects the way in which a user views and organizes a message and hence interprets procedural directions and related imagery. This is within the context of usability testing for a wide variety of users who may not share a first language or have the same method of vision correction.

The results showed that the counter plating gold could inhibit secondary electron and work accurately.
Exploring the Interface Design of Mobile Phone for the Elderly
Authors: Chiuhsiang Joe Lin, Tsung-Ling Hsieh, Wei-Jung Shiang
Venue: Proceedings of the 1st International Conference on Human Centered Design: Held as Part of HCI International 2009 (2009)

This study evaluated the influences of mobile phone interface design on the operating performance of aged people. To achieve the objective, the present research adopted a 2×2 within subject experimental design to develop different experimental treatments based on two types of software interfaces and two types of hardware interfaces. A total of 20 subjects including 10 younger participants (15-30 years old) and 10 older participants (over 40 years old) were tested in this experiment. Three dependent variables were under study. One measure refers to the operating time of subjects who were requested to perform several tasks in the experiment. The second measure refers to the error frequency, defined by the number of incorrect steps that subjects make when they perform the tasks. The third variable was the subjective convenience that was measured by a seven-point Likert scale. Finally, this study discussed design directions in cell phone design for the aged people. The conclusions from this study provided a useful reference for the mobile phone designer.
An approach to summarizing short stories
Authors: Anna Kazantseva
Venue: Proceedings of the Eleventh Conference of the European Chapter of the Association for Computational Linguistics: Student Research Workshop (2006)

This paper describes a system that produces extractive summaries of short works of literary fiction. The ultimate purpose of produced summaries is defined as helping a reader to determine whether she would be interested in reading a particular story. To this end, the summary aims to provide a reader with an idea about the settings of a story (such as characters, time and place) without revealing the plot. The approach presented here relies heavily on the notion of aspect. Preliminary results show an improvement over two na&iuml;ve baselines: a lead baseline and a more sophisticated variant of it. Although modest, the results suggest that using aspectual information may be of help when summarizing fiction. A more thorough evaluation involving human judges is under way.
Digital Medicine: Health Care in the Internet Era, 1st edition
Authors: Darrell M. West, Edward Alan Miller
Venue:  (2009)

Information technology has dramatically changed the way we live our lives in areas ranging from commerce and entertainment to voting. Now, policy advocates and government officials hope to bring the benefits of information technology to health care. Governments, hospitals, doctors, and pharmaceutical manufacturers have placed a tremendous amount of medical information, data, and services online in recent years. Many consumers can visit health department sites and compare performance data on health care providers. Some physicians encourage patients to use e-mail or web messaging as opposed to phone calls or in-office visits for simple medical issues. Increasingly, medical equipment and prescription drug manufacturers are making their products available online. Yet despite this growth in activity, the promise of e-health remains largely unfulfilled. "Digital Medicine" investigates the factors limiting the ability of digital technology to remake health care in the United States and around the world. What political, social, and ethical challenges are presented by online health care? How are racial, ethnic, and other disparities limiting the e-health revolution? How accessible are health-related Internet websites to the disabled, those at basic or below basic levels of literacy, or with limited English proficiency? Are there differences between websites sponsored by public, private and nonprofit organizations that limit technology utilization? How can we close the disparity gap and deal with conflicts of interest that contribute to distrust in the information presented? Darrell West and Edward Miller analyze multiple data sources, including original survey research and website analysis, to study the content of health care-related websites, sponsorship status, public usage, and the relationship between e-health utilization and attitudes about health care in America. They also analyze the different ways in which officials in other countries have implemented health information technology. By drawing on these experiences, "Digital Medicine" helps us understand health care information innovation in a variety of political, social, and economic settings.
Genetic Algorithm Based Scheduling of Radiotherapy Treatments for Cancer Patients
Authors: Dobrila Petrovic, Mohammad Morshed, Sanja Petrovic
Venue: Proceedings of the 12th Conference on Artificial Intelligence in Medicine: Artificial Intelligence in Medicine (2009)

This paper presents a multi-objective model for scheduling of radiotherapy treatments for cancer patients based on genetic algorithms (GA). The model is developed and implemented considering real life radiotherapy treatment processes at Arden Cancer Centre, Coventry, UK. Two objectives are defined: minimisation of the Average patient waiting times and minimisation of Average tardiness of the patient first treatment fractions. Two scenarios are analysed considering the availability of the doctors to approve treatment plans. The schedules generated by the GA using real data collected from the collaborating Cancer Centre have good performance. It is demonstrated that enabling doctors to approve treatment plans instantly has a great impact on Average waiting time and Average tardiness for all patient categories.
CMIC@INEX 2008: Link-the-Wiki Track
Authors: Kareem Darwish
Venue: Advances in Focused Retrieval: 7th International Workshop of the Initiative for the Evaluation of XML Retrieval, INEX 2008, Dagstuhl Castle, Germany, December 15-18, 2008. Revised and Selected Papers (2009)

This paper describes the runs that I submitted to the INEX 2008 Link-the-Wiki track. I participated in the incoming File-to-File and the outgoing Anchor-to-BEP tasks. For the File-to-File task I used a generic IR engine and constructed queries based on the title, keywords, and keyphrases of the Wikipedia article. My runs performed well for this task achieving the highest precision for low recall levels. Further post-hoc experiments showed that constructing queries using titles only produced even better results than the official submissions. For the Anchor-to-BEP task, I used a keyphrase extraction engine developed in-house and I filtered the keyphrases using existing Wikipedia titles. Unfortunately, my runs performed poorly compared to those of other groups. I suspect that this was the result of using many phrases that were not central to articles as anchors.
Webcam-Based Visual Gaze Estimation
Authors: Roberto Valenti, Jacopo Staiano, Nicu Sebe, Theo Gevers
Venue: Proceedings of the 15th International Conference on Image Analysis and Processing (2009)

In this paper we combine a state of the art eye center locator and a new eye corner locator into a system which estimates the visual gaze of a user in a controlled environment (e.g. sitting in front of a screen). In order to reduce to a minimum the computational costs, the eye corner locator is built upon the same technology of the eye center locator, tweaked for the specific task. If high mapping precision is not a priority of the application, we claim that the system can achieve acceptable accuracy without the requirements of additional dedicated hardware. We believe that this could bring new gaze based methodologies for human-computer interactions into the mainstream.
The Monitoring System for Operation Condition of Pumping Wells Based on ARM and the Acceleration Sensor
Authors: Haifeng Tian, Jianping Zhao, Yanfeng Dong
Venue: Proceedings of the 2009 WASE International Conference on Information Engineering - Volume 01 (2009)

The indicator diagram of the pumping well is an important method to know the operation condition of the oil pump. It is a diagram consisting of the displacement and the load of the sucker rod in a complete period. In this paper, the monitoring system for operation conditions of pumping wells is designed based on ARM and the acceleration sensor, and the realization of the hardware and software of every part is presented in details. The system includes the operation condition sensor, the handy data collector and the data management center. The acceleration sensor is proposed in the operation condition sensor instead of the wire-drawing displacement sensor, which enables the system to record the indicator diagram automatically for a long time. Because the innovative information technologies including the ARM, the SD card and the USB communication are involved, this system has many advantages such as very low power consumption, wireless connection, high accuracy and continuous monitoring. The system has been continuously operated for a year and applied by several hundreds of oil wells, and the application proves this system to be workable and effective.
