Literature Mining: Towards Better Understanding of Autism
Authors: Tanja Urbančič, Ingrid Petrič, Bojan Cestnik, Marta Macedoni-Lukšič
Venue: Proceedings of the 11th conference on Artificial Intelligence in Medicine (2007)

In this article we present a literature mining method RaJoLink that upgrades Swanson's ABC model approach to uncovering hidden relations from a set of articles in a given domain. When these relations are interesting from medical point of view and can be verified by medical experts, they represent new pieces of knowledge and can contribute to better understanding of diseases. In our study we analyzed biomedical literature about autism, which is a very complex and not yet sufficiently understood domain. On the basis of word frequency statistics several rare terms were identified with the aim of generating potentially new explanations for the impairments that are observed in the affected population. Calcineurin was discovered as a joint term in the intersection of their corresponding literature. Similarly, NF-kappaB was recognized as a joint term. Pairs of documents that point to potential relations between the identified joint terms and autism were also automatically detected. Expert evaluation confirmed the relevance of these relations.
The Honeywall CD-ROM
Authors: George Chamales
Venue: IEEE Security and Privacy (2004)

For more than a year, Honeynet Project members have been quietly developing a tool to make honeynets faster to deploy and easier to maintain. The tool, called the Honeywall CD-ROM, is a bootable CD capable of installing and configuring a honeywall (the honeynet's control center) in a matter of minutes. Although the Honeywall CD-ROM's designers initially created it to facilitate honeynet deployments, the CD-ROM is customizable for use outside the honeynet environment-for example, to bolster the defense of production networks.
A Hybrid of Particle Swarm Optimization and Hopfield Networks for Bipartite Subgraph Problems
Authors: Jiahai Wang
Venue: Proceedings of the 4th international symposium on Neural Networks: Advances in Neural Networks, Part III (2007)

The bipartite subgraph problem is a classical problem in combinatorial optimization. In this paper, we incorporate a chaotic discrete Hopfield neural network (CDHNN), as a local search scheme, into the discrete particle swarm optimization (DPSO) and develop a hybrid algorithm DPSO-CDHNN for the bipartite subgraph problem. The proposed algorithm not only performs exploration by using the population-based evolutionary search ability of the DPSO, but also performs exploitation by using the CDHNN. Simulation results show that the proposed algorithm has superior ability for bipartite subgraph problem. The ACM Portal is published by the Association for Computing Machinery.

Authors: H. D. B. Gottlob, M. C. Lemme, M. Schmidt, T. J. Echtermeyer, T. Mollenhauer, H. Kurz, K. Cherkaoui, P. K. Hurley, S. B. Newcomb
Venue: Microelectronic Engineering (2008)

In this paper, a process flow well suited for screening of novel high-k dielectrics is presented. In vacuo silicon capping of the dielectrics excludes process and handling induced influences especially if hygroscopic materials are investigated. A gentle, low thermal budget process is demonstrated to form metal gate electrodes by turning the silicon capping into a fully silicided nickel silicide. This process enables the investigation of rare earth oxide based high-k dielectrics and specifically their intrinsic material properties using metal oxide semiconductor (MOS) capacitors. We demonstrate the formation of nickel monosilicide electrodes which show smooth interfaces to the lanthanum- and gadolinium-based high-k oxide films. The dielectrics have equivalent oxide thicknesses of EOT=0.95nm (lanthanum silicate) and EOT=0.6nm (epitaxial gadolinium oxide).
Searchers' relevance judgments and criteria in evaluating web pages in a learning style perspective
Authors: Chariste Papaeconomou, Annemarie F. Zijlema, Peter Ingwersen
Venue: Proceedings of the second international symposium on Information interaction in context (2008)

The paper presents the results of a case study of searcher's relevance criteria used for assessments of Web pages in a perspective of learning style. 15 test persons participated in the experiments based on two simulated work tasks that provided cover stories to trigger their information needs. Two learning styles were examined: Global and Sequential learners. The study applied eye-tracking for the observation of relevance hot spots on Web pages, learning style index analysis and post-search interviews to gain more in-depth information on relevance behavior. Findings reveal that with respect to use of graded relevance scores and number of relevance criteria applied per task and test person there are no significant difference between the different styles. Although there differences are detected in the use of relevance criteria between Global and Sequential learners during assessments, they are statistically insignificant. When interviewed in retrospective the resulting profiles tend to become even similar across learning styles but a shift occurs from instant assessments with content features of web pages replacing topicality judgments as predominant relevance criteria.
First Principle Gas Phase Study of the Trans and Gauche Rotamers of 1,2-Diisocyanoethane, 1,2-Diisocyanodisilane and Isocyano(isocyanomethyl)silane
Authors: Ponnadurai Ramasami
Venue: Proceedings of the 8th international conference on Computational Science, Part II (2008)

The trans and gauche rotamers of 1,2-diisocyanoethane, 1,2-diisocyanodisilane and isocyano(isocyanomethyl)silane have been studied in the gas phase. A transition state has also been obtained for the interconversion of these rotamers. The methods used are MP2 and DFT/B3LYP and the basis sets used for all atoms are 6-311++G(d,p). The optimised geometries, dipole moments, moment of inertia, energies, energy differences and rotational barriers are reported. Vibrational frequencies of the rotamers are presented with appropriate assignments. The results indicate that the trans rotamer is more stable and the G2MP2 rotational energy differences are 2.97 kJ/mol (1,2-diisocyanoethane), 3.02 kJ/mol (isocyano(isocyanomethyl)silane) and 2.12 kJ/mol (1,2-diisocyanodisilane). The rotational barrier for 1,2-diisocyanoethane is larger than its energy difference but the barrier becomes comparable to the energy difference for isocyano(isocyanomethyl)silane.
Development of Three Dimensional Dynamics Simulator with Omnidirectional Vision Model
Authors: Fumitaka Otsuka, Hikari Fujii, Kazuo Yoshida
Venue: RoboCup 2006: Robot Soccer World Cup X (2006)

In the field of robotics, simulators are important tools to verify algorithms. They are required to generate movements and physical interactions of objects based on the dynamics and to simulate outputs of sensors. However, few simulators of robots simulate dynamics of objects and outputs of sensors, in particular omnidirectional cameras, which are effective sensors because they can acquire an omnidirectional field of view at one time. In this study, omnidirectional vision simulators are developed based on the ray casting method. The proposed simulators enables to render accurate omnidirectional images and an intersection test is developed for speeding up. These are able to be used in "Gazebo" which is open source 3D dynamics simulator. The proposed methods are verified through comparison of the rendered images with the images which are obtained by real omnidirectional vision sensor.
Eulogy: Walter W. Jacobs, 1914-1982
Authors: Joseph Blum, Robert L. Kirby, Jack Minker
Venue: IEEE Annals of the History of Computing (1984)

There are a few individuals who, because their work is classified by their government for security reasons, cannot receive the full recognition in the scientific community that they deserve. Walter W. Jacobs, who died of cancer on February 11, 1982, at the age of 67, was one such individual. Although the scientific community at large may not have been aware of his many contributions, the government of the United States of America recognized the importance of his work and awarded him two medals for Exceptional Civilian Service and an additional award of the Legion of Merit. Indeed, the scientific community and the United States owe much to his scientific accomplishments, managerial skills, and foresight.
Embodiment and Perceptual Crossing in 2D
Authors: Marieke Rohde, Ezequiel Paolo
Venue: Proceedings of the 10th international conference on Simulation of Adaptive Behavior: From Animals to Animats (2008)

We present the results from an evolutionary robotics simulation model of a recent unpublished experiment on human perceptual crossing in a minimal virtual two-dimensional environment. These experiments demonstrate that the participants reliably engage in rhythmic interaction with each other, moving along a line. Comparing three types of evolved agents with radically different embodiment (a simulated arm, a two-wheeled robot and an agent generating a velocity vector in Euclidean space), we identify differences in evolved behaviours and structural invariants of the task across embodiments. The simulation results open an interesting perspective on the experimental study and generate hypotheses about the role of arm morphology for the behaviour observed.
Models of multiproduct inventory control under steady demands
Authors: N. M. Kalinin, E. N. Khobotov
Venue: Automation and Remote Control (2008)

Consideration was given to the control of multiproduct inventory under steady demands. Special models and algorithms were proposed to solve such problems and minimize the costs of inventory delivery and carrying. Additionally, the principles of designing the multi-product inventory control systems were discussed.
Supporting Factors in Descriptive Analysis of Brain Ischaemia
Authors: Dragan Gamberger, Nada Lavrač
Venue: Proceedings of the 11th conference on Artificial Intelligence in Medicine (2007)

This paper analyzes two different approaches to the detection of supporting factors used in descriptive induction. The first is based on the statistical comparison of the pattern properties relative to the properties of the entire negative and the entire positive example sets. The other approach uses artificially generated random examples that are added into the original training set. The methodology is illustrated in the analysis of patients suffering from brain ischaemia.
Real-Time Antialiasing of Edges and Contours of Point Rendered Implicit Surfaces
Authors: Dirk J. Harbinson, Ron J. Balsys, Kevin G. Suffern
Venue: Proceedings of the 2008 Fifth International Conference on Computer Graphics, Imaging and Visualisation (2008)

We present various algorithms for antialiasing silhouette edges of manifold and non-manifold implicit surfaces.The algorithms are: object space, edge blur, super-sampling, adaptive pixel-tracing, and jitter-based antialiasing. We discuss the strengths and weaknesses of the approaches and compare the results. We also discuss the antialiasing of contours rendered on implicit surfaces. The algorithms for antialiasing and rendering contours take place in the GPU and so are performed in real time. This allows us, for instance, to animate contours on a surface in real time by changing contour parameters. We give examples showing the results of our antialiasing techniques for various types of contours rendered on surfaces.
Passing Messages to Lonely Numbers
Authors: Heiko Bauke
Venue: Computing in Science and Engineering (2008)

Message-passing methods provide powerful approximation algorithms for problems that can be formulated in terms of (probabilistic) graphical models. These methods find applications in statistical physics, inference, and combinatorial optimization. Sudoku, a popular number puzzle, is a simple optimization problem that message-passing algorithms can help solve. Therefore, Sudoku is an ideal vehicle to demonstrate these methods' strengths and limitations.

Authors: Masaya Yoshikawa, Takeshi Kihira, Hidekazu Terai
Venue: Proceedings of the 9th WSEAS International Conference on Evolutionary Computing (2008)

Reinforcement learning is applied to various fields such as robotics and mechatronics control. The reinforcement learning is an efficient method to control in unknown environment. This paper discusses a new reinforcement learning algorithm using adaptive action value tables. The proposed learning algorithm is based on Genetic Algorithm and enables sharing knowledge among agents. Regarding sharing knowledge, it introduces hierarchical evolutionary mechanism and the knowledge is inherited in one generation. As a result, the proposed algorithm achieves not only effective learning but also robustness. Experiments using pong simulator prove the effectiveness of the proposed algorithm.
Time jitter effect of control circuit on high-Q switched-capacitor filter for radio-communication applications
Authors: Ahmed El Oualkadi, Jean-Marie Paillot, Denis Flandre
Venue: Proceedings of the 7th WSEAS International Conference on Microelectronics, Nanoelectronics, Optoelectronics (2008)

This paper proposes the study of clock time jitter effect on high-Q switched-capacitor filter behavior. A control circuit made up by a ring voltage controlled oscillator (VCO) with XOR gates is used to generate the control signals. According to the correlation of these signals the jitter effect on the signal constellation has been studied. A good agreement between measured and simulation results has been achieved which validate our design methodology.
A new characterization for the m-quasiinvariants of Sn and explicit basis for two row hook shapes
Authors: Jason Bandlow, Gregg Musiker
Venue: Journal of Combinatorial Theory Series A (2008)

In 2002, Feigin and Veselov [M. Feigin, A.P. Veselov, Quasiinvariants of Coxeter groups and m-harmonic polynomials, Int. Math. Res. Not. 10 (2002) 521-545] defined the space of m-quasiinvariants for any Coxeter group, building on earlier work of [O.A. Chalykh, A.P. Veselov, Commutative rings of partial differential operators and Lie algebras, Comm. Math. Phys. 126 (1990) 597-611]. While many properties of those spaces were proven in [P. Etingof, V. Ginzburg, On m-quasi-invariants of a Coxeter group, Mosc. Math. J. 3 (2002) 555-566; M. Feigin, A.P. Veselov, Quasiinvariants of Coxeter groups and m-harmonic polynomials, Int. Math. Res. Not. 10 (2002) 521-545; G. Felder, A.P. Veselov, Action of Coxeter groups on m-harmonic polynomials and Knizhnik-Zamolodchikov equations, Mosc. Math. J. 4 (2003) 1269-1291; A. Garsia, N. Wallach, The non-degeneracy of the bilinear form of m-quasi-invariants, Adv. in Appl. Math. 3 (2006) 309-359. [7]] from this definition, an explicit computation of a basis was only done in certain cases. In particular, in [M. Feigin, A.P. Veselov, Quasiinvariants of Coxeter groups and m-harmonic polynomials, Int. Math. Res. Not. 10 (2002) 521-545], bases for m-quasiinvariants were computed for dihedral groups, including S"3, and Felder and Veselov [G. Felder, A.P. Veselov, Action of Coxeter groups on m-harmonic polynomials and Knizhnik-Zamolodchikov equations, Mosc. Math. J. 4 (2003) 1269-1291] also computed the non-symmetric m-quasiinvariants of lowest degree for general S"n. In this paper, we provide a new characterization of the m-quasiinvariants of S"n, and use this to provide a basis for the isotypic component indexed by the partition [n-1,1]. This builds on a previous paper, [J. Bandlow, G. Musiker, Quasiinvariants of S"3, J. Combin. Theory Ser. A 109 (2005) 281-298], in which we computed a basis for S"3 via combinatorial methods.
Detection and Analysis of Iterative Behavior in Parallel Applications
Authors: Karl Fürlinger, Shirley Moore
Venue: Proceedings of the 8th international conference on Computational Science, Part III (2008)

Many applications exhibit iterative and phase based behavior. We present an approach to detect and analyze iteration phases in applications by recording the control flow graph of the application and analyzing it for loops that represent iterations. Phases are then manually marked and performance profiles are captured in alignment with the iterations. By analyzing how profiles change between capture points, differences in execution behavior between iterations can be uncovered.
3D Mesh Exploration for Smart Visual Interfaces
Authors: Georg Fuchs, Mathias Holst, René Rosenbaum, Heidrun Schumann
Venue: Proceedings of the 10th international conference on Visual Information Systems: Web-Based Visual Information Search and Management (2008)

Today's fast growth of both the number and complexity of digital 3D models results in a number of research challenges. Amongst others, the efficient presentation of, and interaction with, such complex models is essential. It therefore has become more and more important to provide the user with a smart visual interface that presents all the information required in the context of the task at hand in a comprehensive way. In this paper, we present a two-stage concept for the task-oriented exploration of 3D polygonal meshes. An authoring tool uses a combination of automatic mesh segmentation and manual enrichment with semantic information for association with specified exploration goals. This information is then used at runtime to adapt the model's presentation to the task at hand. The exploration of the enriched model can further be supported by interactive tools. 3D lenses are discussed as an example.
Abstractions for model-checking game-theoretic properties of auctions
Authors: E. M. Tadjouddine, Frank Guerin, Wamberto Vasconcelos
Venue: Proceedings of the 7th international joint conference on Autonomous agents and multiagent systems - Volume 3 (2008)

We are interested in verifying game-theoretic properties such as strategyproofness for auction protocols in open agent systems. Model checking provides an automatic way of carrying out such proofs. However it may suffer from state space explosion for large models. To improve the performance of model checking, abstractions were used along with the SPIN model checker. We applied the technique to the Vickrey auction. Numerical results showed the limits of relying solely on SPIN. To reduce the state space required by SPIN, two property-preserving abstraction methods were applied: firstly the classical program slicing technique, which removes irrelevant variables with respect to the property; the second replaces large data, possibly infinite values of variables, with smaller abstract values. This enabled us to model check the strategy-proofness property of the Vickrey auction for unbounded bid ranges and for any number of agents.
σ-Self-Adaptive Weighted Multirecombination Evolution Strategy with Scaled Weights on the Noisy Sphere
Authors: Hans-Georg Beyer, Alexander Melkozerov
Venue: Proceedings of the 10th international conference on Parallel Problem Solving from Nature: PPSN X (2008)

This paper presents a performance analysis of the recently proposed &sigma;-self-adaptive weighted recombination evolution strategy (ES) with scaled weights. The steady state behavior of this ES is investigated for the non-noisy and noisy case, and formulas for the optimal choice of the learning parameter are derived allowing the strategy to reach maximal performance. A comparison between weighted multirecombination ES with &sigma;-self-adaptation (&sigma;SA) and with cumulative step size adaptation (CSA) shows that the self-adaptive ES is able to reach similar (or even better) performance as its CSA counterpart on the noisy sphere.
A Bayesian framework for knowledge driven regression model in micro-array data analysis
Authors: Rong Jin, Luo Si, Christina Chan
Venue: International Journal of Data Mining and Bioinformatics (2008)

This paper addresses the sparse data problem in the linear regression model, namely the number of variables is significantly larger than the number of the data points for regression. We assume that in addition to the measured data points, the prior knowledge about the input variables may be provided in the form of pair wise similarity. We presented a full Bayesian framework to effectively exploit the similarity information of the input variables for linear regression. Empirical studies with gene expression data show that the regression errors can be reduced significantly by incorporating the similarity information derived from gene ontology.
Accelerating Speculative Execution in High-Level Synthesis with Cancel Tokens
Authors: Hagen Gädke, Andreas Koch
Venue: Proceedings of the 4th international workshop on Reconfigurable Computing: Architectures, Tools and Applications (2008)

We present an improved method for scheduling speculative data paths which relies on cancel tokens to undo computations in mis-speculated paths. Performancewise, this method is considerably faster than lenient execution, and faster than any other known approach applicable for general (including non-pipelined) computation structures. We present experimental evidence obtained by implementing our method as part of the high-level language hardware/software compiler COMRADE.
Flux: Enhancing Photo Organization through Interaction and Automation
Authors: Dominikus Baur, Otmar Hilliges, Andreas Butz
Venue: Proceedings of the 9th international symposium on Smart Graphics (2008)

In Flux, an application for digital photo collections, we provide methods for organizing and sharing photos in a convenient manner based on real-world physical interaction on a tabletop system. Additionally, the system supports four different orders based on quality, time, similarity and a combination of the latter two. The problem of scalability, which is especially relevant for a real-world sized photo collection is tackled with a combination of manual hierarchical clustering by the user and the automatic construction of "piles" of similar photos (depending on the currently active order) by the system. In this paper, we present the design goals, the visualization and interaction techniques deployed in Flux.
The CHIL RT07 Evaluation Data
Authors: Susanne Burger
Venue: Multimodal Technologies for Perception of Humans: International Evaluation Workshops CLEAR 2007 and RT 2007, Baltimore, MD, USA, May 8-11, 2007, Revised Selected Papers (2008)

This paper describes the CHIL 2007 evaluation data set provided for the Rich Transcription 2007 Meeting Recognition Evaluation (RT07) in terms of recording setup, scenario, speaker demagogic and transcription process. The corpus consists of 25 interactive seminars recorded at five different recording sites in Europe and the United States in multi-sensory smart rooms. We compare speakers' talk-time ratios in the interactive seminars with lecture data and multi-party meeting data. We show that the length of individual speaker's contributions helps to position interactive seminars between lectures and meetings in terms of speaker interactivity. We also study the differences between the manual transcription of narrow-field and far-field audio recording.
