Acting under Interference by other Agents with unknown Goals
Authors: Nicolaj Søndberg-Jeppesen, Finn Verner Jensen
Venue: Proceeding of the 2008 conference on Tenth Scandinavian Conference on Artificial Intelligence: SCAI 2008 (2008)

We consider the situation where two agents try to solve each their own task in a common environment. A general framework for representing that kind of scenario is presented. The framework is used to model the analysis depth of the opponent agent and to determine an optimal policy under various assumptions on analysis depth of the opponent. The framework is applied on a strategic game, Ausgetrickst, and experiments are reported.
A physically-based human skin reflection model
Authors: Ling Li, Carmen So-Ling Ng
Venue: Proceedings of the 10th WSEAS international conference on Automation & information (2009)

A theoretical reflection model for human skin is presented. A layer of sebum has been included in the three-layer skin reflection model, since it is found over most parts of the body and contributes significantly to the specularity of human skin appearance. The Monte Carlo method is used to simulate the propagation of light in skin tissues. Optical and geometric properties are used as control parameters to influence the surface reflection and subsurface scattering of light within the sebum-covered skin layers. The bi-directional reflectance distribution function (BRDF) obtained from the simulation is used to render the appearance of human skin. Comparisons between the simulated BRDF results and experimental measurements show that the physical simulation is highly realistic.
Searching over Public Administration Legal Documents Using Ontologies
Authors: Diego Berrueta, Jose Emilio Labra, Luis Polo
Venue: Proceeding of the 2006 conference on Knowledge-Based Software Engineering: Proceedings of the Seventh Joint Conference on Knowledge-Based Software Engineering (2006)

In this paper, we apply Semantic Web technologies to the creation of an improved search engine over legal and public administration documents. Conventional search strategies based on syntactic matching of tokens offer little help when the users' vocabulary and the documents' vocabulary differ. This is often the case in public administration documents. We present a semantic search tool that fills this gap using Semantic Web technologies, in particular, ontologies and controlled vocabularies, and a hybrid search approach, avoiding the expensive tagging of documents.

Venue: Proceedings of the 10th WSEAS international conference on Automation & information (2009)

Most work in Artificial Intelligence shall review the balance of classic game theory to predict agent behavior in such positions. In this paper introduce sure competitive analysis. This approach by bridging the gap between the norms of the desired path of artificial intelligence, where a strategy should be selected in order to ensure an end result and a balanced analysis. We show that a strategy without risk level is able to guarantee the value obtained in the Nash equilibrium, by more scientific methods of classical computers. Then we discuss the concept of competitive strategy and secure we illustrate how it is used in a decentralized load balanced position, typical network problems. In particular, show that when we have many agents, it is possible to guarantee a final result expected, which is a factor of 8/9 of the final result obtained in the Nash equilibrium. Finally we discuss extending the above concept in Bayesian game and illustrated their use in a basic structure of the auction.
Linear Time Algorithms for Finding a Dominating Set of Fixed Size in Degenerated Graphs
Authors: Noga Alon, Shai Gutner
Venue: Algorithmica (2009)

There is substantial literature dealing with fixed parameter algorithms for the dominating set problem on various families of graphs. In this paper, we give a k O(dk) n time algorithm for finding a dominating set of size at most k in a d-degenerated graph with n vertices. This proves that the dominating set problem is fixed-parameter tractable for degenerated graphs. For graphs that do not contain K h as a topological minor, we give an improved algorithm for the problem with running time (O(h)) hk n. For graphs which are K h -minor-free, the running time is further reduced to (O(log&#x2009;h)) hk/2 n. Fixed-parameter tractable algorithms that are linear in the number of vertices of the graph were previously known only for planar graphs. For the families of graphs discussed above, the problem of finding an induced cycle of a given length is also addressed. For every fixed H and k, we show that if an H-minor-free graph G with n vertices contains an induced cycle of size k, then such a cycle can be found in O(n) expected time as well as in O(nlog&#x2009;n) worst-case time. Some results are stated concerning the (im)possibility of establishing linear time algorithms for the more general family of degenerated graphs.

Authors: Leszek Demkowicz, Jason Kurtz, David Pardo, Maciej Paszynski, Waldemar Rachowicz, Adam Zdunek
Venue:  (2007)

With a focus on 1D and 2D problems, the first volume of Computing with hp-Adaptive Finite Elements prepared readers for the concepts and logic governing 3D code and implementation. Taking the next step in hp technology, Volume II Frontiers: Three-Dimensional Elliptic and Maxwell Problems with Applications presents the theoretical foundations of the 3D hp algorithm and provides numerical results using the 3Dhp code developed by the authors and their colleagues. The first part of the book focuses on fundamentals of the 3D theory of hp methods as well as issues that arise when the code is implemented. After a review of boundary-value problems, the book examines exact hp sequences, projection-based interpolation, and De Rham diagrams. It also presentsthe 3D version of the automatic hp-adaptivity package, a two-grid solver for highly anisotropic hp meshes and goal-oriented Krylov iterations, and a parallel implementation of the 3D code. The second part explores several recent projects in which the 3Dhp code was used and illustrates how these applications have greatly driven the development of 3D hp technology. It encompasses acoustic and electromagnetic (EM) scattering problems, an analysis of complex structures with thin-walled components, and challenging simulations of logging tools. The book concludes with a look at the future of hp methods. Spearheaded by a key developer of this technology with more than 20 years of research in the field, this self-contained, comprehensive resource will help readers overcome the difficulties in coding hp-adaptive elements.
Medium access controlfacing the reality of WSN deployments
Authors: Romain Kuntz, Antoine Gallais, Thomas Noel
Venue: ACM SIGCOMM Computer Communication Review (2009)

Although research on algorithms and communication protocols in Wireless Sensor Networks (WSN) has yielded a tremendous effort so far, most of these protocols are hardly used in real deployments nowadays. Several reasons have been put forward in recent publications. In this paper, we further investigate this trend from a Medium Access Control (MAC) perspective by analyzing both the reasons behind successful deployments and the characteristics of the MAC layers proposed in the literature. The effort allocated to develop suitable protocols from scratch every new deployment could however be minimized by using already existing contributions which provide code reuse and adaptive protocols. Though we advocate their use for nowadays deployments, we have identified several shortcomings in foreseen scenarios for which we provide guidelines for future researches.

Morphing in periodic tactile signals
Authors: Karon E. MacLean, Mario J. Enriquez, Tian Lim
Venue: Proceedings of the World Haptics 2009 - Third Joint EuroHaptics conference and Symposium on Haptic Interfaces for Virtual Environment and Teleoperator Systems (2009)

Humans naturally use both categorical and continuous structures when classifying perceptual experiences. However, design of haptic information displays is eased by the availability of design parameters that can be smoothly modulated along a continuous dimension. Taking guidance from visual and auditory media design, we identified and validated a perceptually successful “morph” function that modulates a tactile vibration between two disparate endpoints (a square and a triangle or sine wave), by varying the magnitude of the vertical (highest frequency content) component of the waveform. This finding suggests a specific psychonomic function related to frequency perception, points towards a practical utility in haptic information design, and supports reflections on further possibilities for haptic morphing.
An Adaptive Hybrid Filtering for Removing Impulse Noise in Color Images
Authors: Xuan Guo, Baoping Guo, Tao Hu, Ou Yang
Venue: Proceedings of the 6th International Symposium on Neural Networks: Advances in Neural Networks - Part III (2009)

An adaptive hybrid filter combining a group of sigma vector median filters with different thresholds with a filter based on neuro-fuzzy system is proposed for color image processing. The first subunit of the proposed filter is six sigma vector median filters, their outputs are used as optimum initial points to input the second subunit constituted by a simple Sugeno-type neuro-fuzzy system, and then the optimized result is obtained from the output of the second subunit. The parameters of the neuro-fuzzy model are automatically tuned and fixed by a learning method based on genetic algorithm. The results have indicated that the design of the proposed hybrid filter has met the requirement of removing impulse noise and preserving details. The proposed filter performs better than other filters.
Over-provisioned multicore systems
Authors: Gurindar S. Sohi
Venue:  (2008)

Technology scaling has provided system designers with an exploding transistor budget, far more than what was available when the core principles behind many existing commodity microprocessors were envisioned. This tremendous growth also brings forth a whole new set of engineering challenges involving power density, thermal efficiency, and so on. In particular, the power constraint is becoming a first order design consideration in microprocessor designs. In the landscape of general purpose processors, power limited designs designate a significant paradigm shift from the area limited designs of the past. This dissertation proposes a model to capture the first order impact of the power constraint. Denoted as the Simultaneously Active Fraction (SAF), this metric represents the fraction of the entire chip resources that can be active simultaneously, given a target power envelope. As the improvement in the energy efficiency of individual transistor devices lags behind the growth in their integration capacity, the dissertation finds that the SAF is monotonically decreasing in each successive technology generation. In the context of rapidly shrinking SAF, this dissertation investigates a novel multicore design paradigm: Over-provisioned Multicore System (OPMS). An OPMS is a class of multicores that by design provision more processing core resources than that can be kept active for their target Thermal Design Power (TDP). Since only a subset of the on-chip cores are active at any given time, this design paradigm affords tremendous flexibility in assigning computation on processing cores, facilitating many novel techniques in this broad framework. To demonstrate a concrete application of this framework, the dissertation proposes Computation Spreading (CSP): a new model for distributing the collective work from multithreaded applications. CSP aims to collocate similar computation fragments from different threads on the same core, while distributing dissimilar computation fragments from the same thread across multiple cores. Under CSP, on-chip cores in an OPMS are dynamically specialized via retaining mutually exclusive predictive states. The dissertation demonstrates the effectiveness of CSP in an OPMS through a rigorous evaluation of performance, energy efficiency, and several design trade-offs.
Slavonic information extraction and partial parsing
Authors: Adam Przepiórkowski
Venue: Proceedings of the Workshop on Balto-Slavonic Natural Language Processing: Information Extraction and Enabling Technologies (2007)

Information Extraction (IE) often involves some amount of partial syntactic processing. This is clear in cases of interesting high-level IE tasks, such as finding information about who did what to whom (when, where, how and why), but it is also true in case of simpler IE tasks, such as finding company names in texts. The aim of this paper is to give an overview of Slavonic phenomena which pose particular problems for IE and partial parsing, and some phenomena which seem easier to treat in Slavonic than in Germanic or Romance; I also mention various tools which have been used for the partial processing of Slavonic.
Application of multi-class support vector machines for power system on-line static security assessment using DT - based feature and data selection algorithms
Authors: M. Mohammadi, G. B. Gharehpetian
Venue: Journal of Intelligent Fuzzy Systems: Applications in Engineering and Technology (2009)

This paper presents a multi-class Support Vector Machine (SVM) based algorithm for on-line static security assessment of the power systems. The proposed SVM based security assessment algorithm has a very small training time and space in comparison with the traditional machine learning methods such as Artificial Neural Networks (ANN) based algorithms. In addition, the proposed algorithm is faster than existing algorithms. One of the main points, to apply a machine learning method is feature selection. In this paper, a new Decision Tree (DT) based feature selection algorithm has been presented. The proposed SVM algorithm has been applied to New England 39-bus power system. The simulation results show the effectiveness and the stability of the proposed method for on-line static security assessment. The effectiveness of the proposed feature selection algorithm has been investigated, too. The proposed feature selection algorithm has been compared with different feature selection algorithms. The simulation results demonstrate the effectiveness of the proposed feature algorithm.

Patterns of Ink in Water and Air: Creating Radial Spreads of Ink in Water
Authors: Pery Burge
Venue: Journal of Visualization (2009)

Radial spreads are made by placing different types of ink and paint over each other. Then, when gravity 'activates' the spread, causing the ink to move outward, the resulting patterns of ink are photographed. Recent work shows how different types of ink react to the force of the spread (by, for instance, forming thin films, or becoming filamentous). Different types of ink can be used in conjunction to reveal different parts of the spread. Regular shapes in tessellations, underwater 3D forms, and airborne radial spreads have been observed. Radial spreads of ink in water can be seen in terms of both art and science. Artistic aspects include an exploration of ink textures, and comparisons are made with other natural and man-made materials. Parallels between radial spreads and organic life forms are made, and new juxtapositions of the 'birth, life and death' of the spreads are found. Connections are made between the small-scale world of ink in water, and large-scale objects, e.g. cosmic phenomena. Ambiguous imagery, requiring an imaginative contribution from the viewer, is explored. Long-term aims are to collaborate with those interested in the science of diffusion to build up visual profiles of inks, and also to develop 3D chromatography. Artistically, links with other natural forms will be explored. More images are at www.chronoscapes.co.uk.
A Bayesian regression model for multivariate functional data
Authors: Ori Rosen, Wesley K. Thompson
Venue: Computational Statistics Data Analysis (2009)

In this paper we present a model for the analysis of multivariate functional data with unequally spaced observation times that may differ among subjects. Our method is formulated as a Bayesian mixed-effects model in which the fixed part corresponds to the mean functions, and the random part corresponds to individual deviations from these mean functions. Covariates can be incorporated into both the fixed and the random effects. The random error term of the model is assumed to follow a multivariate Ornstein-Uhlenbeck process. For each of the response variables, both the mean and the subject-specific deviations are estimated via low-rank cubic splines using radial basis functions. Inference is performed via Markov chain Monte Carlo methods.
Modelling and forecasting vehicle stocks using the trends of stochastic Gompertz diffusion models: The case of Spain
Authors: R. Gutiérrez, R. Gutiérrez-Sánchez, A. Nafidi
Venue: Applied Stochastic Models in Business and Industry (2009)

In the present study, we treat the stochastic homogeneous Gompertz diffusion process (SHGDP) by the approach of the Kolmogorov equation. Firstly, using a transformation in diffusion processes, we show that the probability transition density function of this process has a lognormal time-dependent distribution, from which the trend and conditional trend functions and the stationary distribution are obtained. Second, the maximum likelihood approach is adapted to the problem of parameters estimation in the drift and the diffusion coefficient using discrete sampling of the process, then the approximated asymptotic confidence intervals of the parameter are obtained. Later, we obtain the corresponding inference of the stochastic homogeneous lognormal diffusion process as limit from the inference of SHGDP when the deceleration factor tends to zero. A statistical methodology, based on the above results, is proposed for trend analysis. Such a methodology is applied to modelling and forecasting vehicle stocks. Finally, an application is given to illustrate the methodology presented using real data, concretely the total vehicle stocks in Spain. Copyright &copy; 2008 John Wiley & Sons, Ltd.
Achieving predictable performance through better memory controller placement in many-core CMPs
Authors: Dennis Abts, Natalie D. Enright Jerger, John Kim, Dan Gibson, Mikko H. Lipasti
Venue: Proceedings of the 36th annual international symposium on Computer architecture (2009)

In the near term, Moore's law will continue to provide an increasing number of transistors and therefore an increasing number of on-chip cores. Limited pin bandwidth prevents the integration of a large number of memory controllers on-chip. With many cores, and few memory controllers, where to locate the memory controllers in the on-chip interconnection fabric becomes an important and as yet unexplored question. In this paper we show how the location of the memory controllers can reduce contention (hot spots) in the on-chip fabric and lower the variance in reference latency. This in turn provides predictable performance for memory-intensive applications regardless of the processing core on which a thread is scheduled. We explore the design space of on-chip fabrics to find optimal memory controller placement relative to different topologies (i.e. mesh and torus), routing algorithms, and workloads.
SCOVO: Using Statistics on the Web of Data

Venue: Proceedings of the 6th European Semantic Web Conference on The Semantic Web: Research and Applications (2009)

Statistical data is present everywhere--from governmental bodies to economics, from life-science to industry. With the rise of the Web of Data, the need for sharing, accessing, and using this data has entered a new stage. In order to enable proprietary, closed-world formats, to enter the Web of Data, we propose a framework for modelling and publishing statistical data. To illustrate the usefulness of our approach we demonstrate its application in real-world statistical datasets.
Anti-Ramsey numbers of doubly edge-critical graphs
Authors: Tao Jiang, Oleg Pikhurko
Venue: Journal of Graph Theory (2009)

Given a graph H and a positive integer n, Anti-Ramsey number AR(n, H) is the maximum number of colors in an edge-coloring of Kn that contains no polychromatic copy of H. The anti-Ramsey numbers were introduced in the 1970s by Erd&odblac;s, Simonovits, and S&oacute;s, who among other things, determined this function for cliques. In general, few exact values of AR(n, H) are known. Let us call a graph H doubly edge-critical if &chi;(H-e)&ge;p+ 1 for each edge e&isin;E(H) and there exist two edges e1, e2 of H for which &chi;(H-e1-e2)=p. Here, we obtain the exact value of AR(n, H) for any doubly edge-critical H when n&ges;n0(H) is sufficiently large. A main ingredient of our proof is the stability theorem of Erd&odblac;s and Simonovits for the Tur&aacute;n problem. &copy; 2009 Wiley Periodicals, Inc. J Graph Theory 61: 210&ndash;218, 2009
