Reflections on the Interdisciplinary Collaborative Design of Mapping the Universe
Authors: Chaomei Chen, Jian Zhang, Michael S. Vogeley
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part IV: Interacting in Various Application Domains (2009)

We describe our experience of developing scientific software in an ongoing multidisciplinary research project participated by information scientists and astronomers. In particular, we reflect on how the interdisciplinary collaboration is facilitated by the development of a unique boundary object --- a hybrid map of the Universe and scientific discoveries. With reference to theories of interdisciplinary communication, we underline that information visualization serves a fundamental role in scientific software development. The impact of information visualization can go far beyond the content representation, and can facilitate communications across distinct disciplines.
Context information exchange and sharing in a peer-to-peer community: a video annotation scenario
Authors: Roberto Fagá,  Jr., Bruno C. Furtado, Felipe Maximino, Renan G. Cattelan, Maria da Graça C. Pimentel
Venue: Proceedings of the 27th ACM international conference on Design of communication (2009)

The literature reports many efforts toward supporting video annotation. In this paper, we present a peer-to-peer model for the exchange of context information and user annotations over video. The Context-Aware Peer-to-Peer Architecture (CAPPA) exploits the automatic capture of the user-interaction with personal devices, employs ontologies to store context information, and uses the context information to organize users in P2P groups for the collaborative exchange of information. We present our proposed model by discussing a prototype system, called CAPPA Service (CAPPAS), which allows users to create and to join peer-to-peer groups using Web-based social communities. Using CAPPAS, users are able to create multimodal annotations while watching videos. The service deploys a capture mode which can be adapted according to the context information collected from the P2P network. CAPPAS customization features include the adaptation of its graphical interfaces according to context information, and the automatic suggestion of text completion during annotation.
Improving Time Series Forecasting by Discovering Frequent Episodes in Sequences
Authors: Francisco Martínez-Álvarez, Alicia Troncoso, José C. Riquelme
Venue: Proceedings of the 8th International Symposium on Intelligent Data Analysis: Advances in Intelligent Data Analysis VIII (2009)

This work aims to improve an existing time series forecasting algorithm ---LBF--- by the application of frequent episodes techniques as a complementary step to the model. When real-world time series are forecasted, there exist many samples whose values may be specially unexpected. By the combination of frequent episodes and the LBF algorithm, the new procedure does not make better predictions over these outliers but, on the contrary, it is able to predict the apparition of such atypical samples with a great accuracy. In short, this work shows how to detect the occurrence of anomalous samples in time series improving, thus, the general forecasting scheme. Moreover, this hybrid approach has been successfully tested on electricity-related time series.
A Network Routing Algorithm Based on the Coalitional Game Theory
Authors: JingYu Su, WeiYi Liu, Kun Yue
Venue: Proceedings of the 2009 International Conference on Computational Intelligence and Natural Computing - Volume 02 (2009)

Network routing has a direct impact on the fairness and efficiency of the whole network .In order to improve the fairness of the network, each node should take into account the choices of other nodes. In this paper, a routing algorithm was proposed on the basis of the coalitional game theory. First, different coalitions will be formed dynamically in the routing process. Then the solutions to these coalitions will be given in the form of Shapley value that is considered to be the symbol of fairness in the game theory. Accordingly, the expected payoffs of the nodes are defined, and the characteristic functions of the coalitions form by network nodes are given. Finally, a method is presented for distributing the probabilities fairly to each routing path in a coalition. Experimental results show that our method is effective.
Online word games for semantic data collection
Authors: David Vickrey, Aaron Bronzan, William Choi, Aman Kumar, Jason Turner-Maier, Arthur Wang, Daphne Koller
Venue: Proceedings of the Conference on Empirical Methods in Natural Language Processing (2008)

Obtaining labeled data is a significant obstacle for many NLP tasks. Recently, online games have been proposed as a new way of obtaining labeled data; games attract users by being fun to play. In this paper, we consider the application of this idea to collecting semantic relations between words, such as hypernym/hyponym relationships. We built three online games, inspired by the real-life games of Scattergories&trade; and Taboo&trade;. As of June 2008, players have entered nearly 800,000 data instances, in two categories. The first type of data consists of category/answer pairs ("Types of vehicle","car"), while the second is essentially free association data ("submarine","underwater"). We analyze both types of data in detail and discuss potential uses of the data. We show that we can extract from our data set a significant number of new hypernym/hyponym pairs not already found in WordNet.
Reasoning with incomplete initial information and nondeterminism in situation calculus
Authors: Lars Karlsson
Venue: Proceedings of the Fifteenth international joint conference on Artifical intelligence - Volume 2 (1997)

Situation Calculus is arguably the most widely studied and used formalism for reasoning about action and change. The main reason for its popularity is the ability to reason about different action sequences as explicit objects. In particular, planning can be formulated as an existence problem. This paper shows how these properties break down when incomplete information about the initial state and nondeterministic action effects are introduced, basically due to the fact that this incompleteness is not adequately manifested on the object level. A version of Situation Calculus is presented which adequately models the alternative ways the world can develop relative to a choice of actions.
Automatic skeletal bone age assessment by integrating EMROI and CROI processing
Authors: D. Giordano, C. Spampinato, G. Scarciofalo, R. Leonardi
Venue: Proceedings of the 2009 IEEE International Workshop on Medical Measurements and Applications (2009)

In this work we propose a fully automatic system for bone age evaluation, according to the Tanner and Whitehouse method (TW2), based on the integration between EMROI and CROI analysis, which ensures accurate bone age assessment for the entire age range (0–10). For both approaches novel segmentation techniques will be proposed. In detail, for the CROI analysis the bones extraction has been carried out by integrating anatomical knowledge of the hand and trigonometric concepts, whereas the TW2 stage assignment is implemented by combining the active contour models (ACM) and derivative difference of Gaussian (DrDoG) filter. For the EMROI analysis, image processing techniques and geometrical features analysis, based on difference of Gaussian (DoG), are proposed. The experimental results were conducted on a set of 30 X-Rays, reaching performances of about 87%. The performances of the proposed method are affected by the detection and extraction of the Trapezium and Trapezoid (50%). Without considering such bones the success rate raises to 91%.

Authors: Xinran Peng, Shuang Kang, Lin Zhang, Ying Zhang, Daming Hu, Weidong Yao
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 03 (2009)

Based on the practical monitoring data of Erlongshan Reservoir, the paper estimated the status of the eutrophication by the comprehensive trophic state index method. The results indicated that the Erlongshan Reservoir was between mesotropher and Light eutropher with the index from 46.5903 to 57.3904. The degree of eutrophication was in the order of high flow period>average and low period. According to the analysis on the variation law of mass concentration ratio of TN to TP and available nitrogen to resolvable orthophosphate, determining the limiting factor for eutrophication was phosphorus in Erlongshan Reservoir.
The Research of Quality Cost Efficiency with Considering the Implicit Cost Based on Non-parametric Analysis
Authors: Yao Gu, Lan Guo, Qingyu Sun
Venue: Proceedings of the 2009 Second International Symposium on Electronic Commerce and Security - Volume 02 (2009)

The estimation of the quality cost efficiency is the important content of quality management, and implicit cost of quality is the important factor which impact quality management. In this paper, we divided the production processes into ‘n’ processes according with the theory of product life-cycle. We are the first to use non-parametric data envelopment analysis (DEA) method for estimating the quality cost efficiency of every process on the condition of considering the implicit cost. We innovated to put forward a method for dealing with implicit cost which is used the function of quality cost and variable weight theory. Examples showed that the method is rationality and effectiveness, as it utilizes an open system view of today’s modern business organization and the competitive environment in which it operates.

Authors: Han Li, Liu Yue
Venue: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 01 (2009)

This study presents a speed control design for switched reluctance motor (SRM) drive powered by Fuzzy Variable Structure Control (FVSC) system. The working principle of SRM equipment is that reluctance minimization. The whole control mechanism consists of switching function and VSC law. The design of fuzzy control laws proposed guarantee the group of buffeting is minimized. This controller is going to be applied to speed control of SRM equipment. Finally, simulation results and comparisons between PID and VSC reliable designs are presented to illustrate the merits of the proposed scheme. Although the proposed design is a stage of simulation, it may provide a guideline for active design in the industrial production.
OpenLIDS: a lightweight intrusion detection system for wireless mesh networks
Authors: Fabian Hugelshofer, Paul Smith, David Hutchison, Nicholas J.P. Race
Venue: Proceedings of the 15th annual international conference on Mobile computing and networking (2009)

Wireless mesh networks are being used to provide Internet access in a cost efficient manner. Typically, consumer-level wireless access points with modified software are used to route traffic to potentially multiple back-haul points. Malware infected computers generate malicious traffic, which uses valuable network resources and puts other systems at risk. Intrusion detection systems can be used to detect such activity. Cost constraints and the decentralised nature of WMNs make performing intrusion detection on mesh devices desirable. However, these devices are typically resource constrained. This paper describes the results of examining their ability to perform intrusion detection. Our experimental study shows that commonly-used deep packet inspection approaches are unreliable on such hardware. We implement a set of lightweight anomaly detection mechanisms as part of an intrusion detection system, called OpenLIDS. We show that even with the limited hardware resources of a mesh device, it can detect current malware behaviour in an efficient way.
Are very large n-best lists useful for SMT?
Authors: Saša Hasan, Richard Zens, Hermann Ney
Venue: Human Language Technologies 2007: The Conference of the North American Chapter of the Association for Computational Linguistics; Companion Volume, Short Papers on XX (2007)

This paper describes an efficient method to extract large n-best lists from a word graph produced by a statistical machine translation system. The extraction is based on the k shortest paths algorithm which is efficient even for very large k. We show that, although we can generate large amounts of distinct translation hypotheses, these numerous candidates are not able to significantly improve overall system performance. We conclude that large n-best lists would benefit from better discriminating models.
Networking Middleware and Online-Deployment Mechanisms for Java-Based Games
Authors: Chris Carter, Abdennour Rhalibi, Madjid Merabti, Marc Price
Venue: Transactions on Edutainment II (2009)

Currently, web-based online gaming applications are predominately utilising Adobe Flash or Java Applets as their core technologies. These games are often casual, two-dimensional games and do not utilise the specialist graphics hardware which has proliferated across modern PCs and Consoles. Multi-user online game play in these titles is often either non-existent or extremely limited. Computer games applications which grace the current generation of consoles and personal computers are designed to utilise the increasingly impressive hardware power at their disposal. However, these are commonly distributed using a physical medium or deployed through custom, proprietary networking mechanisms and rely upon platform-specific networking APIs to facilitate multi-user online game play. In order to unify the concepts of these disparate styles of gaming, this paper presents two interconnected systems which are implemented using Java Web Start and JXTA P2P technologies, providing a platform-independent framework capable of deploying hardware accelerated cross-platform, cross-browser online-enabled Java games, as part of the Homura Project.
Cross-scale, cross-pathway evaluation using an agent-based non-small cell lung cancer model
Authors: Zhihui Wang, Christina M. Birch, Jonathan Sagotsky, Thomas S. Deisboeck
Venue: Bioinformatics (2009)

We present a multiscale agent-based non-small cell lung cancer model that consists of a 3D environment with which cancer cells interact while processing phenotypic changes. At the molecular level, transforming growth factor β (TGFβ) has been integrated into our previously developed in silico model as a second extrinsic input in addition to epidermal growth factor (EGF). The main aim of this study is to investigate how the effects of individual and combinatorial change in EGF and TGFβ concentrations at the molecular level alter tumor growth dynamics on the multi-cellular level, specifically tumor volume and expansion rate. Our simulation results show that separate EGF and TGFβ fluctuations trigger competing multi-cellular phenotypes, yet synchronous EGF and TGFβ signaling yields a spatially more aggressive tumor that overall exhibits an EGF-driven phenotype. By altering EGF and TGFβ concentration levels simultaneously and asynchronously, we discovered a particular region of EGF-TGFβ profiles that ensures phenotypic stability of the tumor system. Within this region, concentration changes in EGF and TGFβ do not impact the resulting multi-cellular response substantially, while outside these concentration ranges, a change at the molecular level will substantially alter either tumor volume or tumor expansion rate, or both. By evaluating tumor growth dynamics across different scales, we show that, under certain conditions, therapeutic targeting of only one signaling pathway may be insufficient. Potential implications of these in silico results for future clinico-pharmacological applications are discussed.

Fusing procedural and declarative planning goals for nondeterministic domains
Authors: Dzmitry Shaparau, Marco Pistore, Paolo Traverso
Venue: Proceedings of the 23rd national conference on Artificial intelligence - Volume 2 (2008)

While in most planning approaches goals and plans are different objects, it is often useful to specify goals that combine declarative conditions with procedural plans. In this paper, we propose a novel language for expressing temporally extended goals for planning in nondeterministic domains. The key feature of this language is that it allows for an arbitrary combination of declarative goals expressed in temporal logic and procedural goals expressed as plan fragments. We provide a formal definition of the language and its semantics, and we propose an approach to planning with this language in nondeterministic domains. We implement the planning framework and perform a set of experimental evaluations that show the potentialities of our approach.
Experience with Establishment of Reusable and Certifiable Safety Lifecycle Model within ABB
Authors: Zaijun Hu, Carlos G. Bilich
Venue: Proceedings of the 28th International Conference on Computer Safety, Reliability, and Security (2009)

One basic requirement for a functional safety development project is to establish a SIL-compliant safety lifecycle model. For a company with a big family of safety-related products and a great number of development projects like ABB, it would be very time-consuming and cost-intensive for each safety development project to develop a safety lifecycle model. One approach for managing the corresponding costs and effort is to create a common lifecycle model that fulfills the SIL requirements and can be reused by safety-related projects. In this paper we are going to present such a common safety lifecycle model, its structure and components, and our experience on how to establish and apply it in safety-related product development projects. The paper analyzes the design constraints for the development of a common safety lifecycle model such as complexity, flexibility, simplicity, conformity and the safety integrity. It shows how these constraints drive the design of the safety lifecycle model to be developed. Our design concept, design considerations, development strategy, and our experience in establishing such a common safety lifecycle model will also be discussed in the paper.

Web services composition technology is promising technology to efficiently integrate heterogeneous, distributed and legacy software system. Performance becomes the key issue when web services composition model complex and mission-critical application. The defect of design can result in the performance bottleneck problem in the running time. In this paper, we propose a simulation-based model for the business process defined by WS-BPEL. Our model takes advantage of General Stochastic Petri Net to simulate the control flow and the transaction behavior of WS-BPEL through constructing the state transition space of composite web service. Therefore, our simulation model can accurately obtain the performance prosperities with the smaller cost in contrast to building experimental system.

Authors: Yu Shibuya, Keiichiro Nagatomo, Kazuyoshi Murata, Itaru Kuramoto, Yoshihiro Tsujino
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)

In our previous work, a throwing method to move an object for long distance in 3D information space on a mobile device was proposed. With the method, as we throw the object to move it far away in the real world, we can throw the virtual object in 3D information space. This simple throwing method was improved by adding following three functions. They were real time adjusting the direction of moving object, moving viewpoint to follow the thrown object, and initializing viewpoint after the movement. The purpose of this paper is to examine the performance of the improved throwing method to move the object for long distance in 3D information space. From the experiment, it is found that the improved throwing method is efficient to move the object for long distance in 3D information space on mobile devices.

And the financial aggregation in Shanghai is also affect the economic growth of Jiangsu province and Zhejiang province.
The cerebral basis of mapping nonsymbolic numerical quantities onto abstract symbols: An fmri training study
Authors: Ian M. Lyons, Daniel Ansari
Venue: Journal of Cognitive Neuroscience (2009)

Although significant insights into the neural basis of numerical and mathematical processing have been made, the neural processes that enable abstract symbols to become numerical remain largely unexplored in humans. In the present study, adult participants were trained to associate novel symbols with nonsymbolic numerical magnitudes (arrays of dots). Functional magnetic resonance imaging was used to examine the neural correlates of numerical comparison versus recognition of the novel symbols after each of two training stages. A left-lateralized fronto-parietal network, including the intraparietal sulcus, the precuneus, and the dorsal prefrontal cortex, was more active during numerical comparison than during perceptual recognition. In contrast, a network including bilateral temporal-occipital regions was more active during recognition than comparison. A whole-brain three-way interaction revealed that those individuals who had higher scores on a postscan numerical task (measuring their understanding of the global numerical organization of the novel symbols) exhibited increasing segregation between the two tasks in the bilateral intraparietal sulci as a function of increased training. Furthermore, whole-brain regression analysis showed that activity in the left intraparietal sulcus was systematically related to the effect of numerical distance on accuracy. These data provide converging evidence that parietal and left prefrontal cortices are involved in learning to map numerical quantities onto visual symbols. Only the parietal cortex, however, appeared systematically related to the degree to which individuals learned to associate novel symbols with their numerical referents. We conclude that the left parietal cortex, in particular, may play a central role in imbuing visual symbols with numerical meaning.
