Mutually Coordinated Anticipatory Multimodal Interaction
Authors: Anton Nijholt, Dennis Reidsma, Herwin Welbergen, Rieks Akker, Zsofia Ruttkay
Venue: Verbal and Nonverbal Features of Human-Human and Human-Machine Interaction: COST Action 2102 International Conference, Patras, Greece, October 29-31, 2007. Revised Papers (2008)

We introduce our research on anticipatory and coordinated interaction between a virtual human and a human partner. Rather than adhering to the turn taking paradigm, we choose to investigate interaction where there is simultaneous expressive behavior by the human interlocutor and a humanoid. Various applications in which we can study and specify such behavior, in particular behavior that requires synchronization based on predictions from performance and perception, are presented. Some observations concerning the role of predictions in conversations are presented and architectural consequences for the design of virtual humans are drawn.
Simulating crowd phenomena in African markets
Authors: Flora Ponjou Tasse, Kevin Glass, Shaun Bangay
Venue: Proceedings of the 6th International Conference on Computer Graphics, Virtual Reality, Visualisation and Interaction in Africa (2009)

Crowd simulation is an important feature in the computer graphics field. Typical implementations simulate battle scenes, emergency situations, safety issues or add content to virtual environments. The problem stated in this paper falls in the last category. We present a crowd simulation behavioural model which allows us to simulate identified phenomena in popular local African markets such as narrow street flows and crowd formation around street performances. We propose a three-tier architecture model enable to produce intentions, perform path planning and control movement. We demonstrate that this approach produces the desired behaviour associated with crowds in an African market, which includes navigation, flow formation and circle creation.

Authors: Jingjun Zhang, Yuzhen Dong, Ruizhen Gao, Yanmin Shang
Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 01 (2009)

This paper introduces triangulation theory into genetic algorithm and with which, the optimization problem will be translated into a fixed point problem. An improved genetic algorithm is proposed by virtue of the concept of relative coordinates genetic coding, designs corresponding crossover and mutation operator. Through genetic algorithms to overcome the triangulation of the shortcomings of human grade, it can start from any point to find the most advantages. Gradually fine mesh will be introduced the idea of genetic algorithms so that the search area gradually decreased, improving the efficiency of search. Finally, examples demonstrate the effectiveness of this method.
A user study on visualizing directed edges in graphs
Authors: Danny Holten, Jarke J. van Wijk
Venue: Proceedings of the 27th international conference on Human factors in computing systems (2009)

Graphs are often visualized using node-link representations: vertices are depicted as dots, edges are depicted as (poly)lines connecting two vertices. A directed edge running from vertex A to B is generally visualized using an arrow representation: a (poly)line with a triangular arrowhead at vertex B. Although this representation is intuitive, it is not guaranteed that a user is able to determine edge direction as quickly and unambiguously as possible; alternative representations that exhibit less occlusion and visual clutter might be better suited. To investigate this, we developed five additional directed-edge representations using combinations of shape and color. We performed a user study in which subjects performed different tasks on a collection of graphs using these representations and combinations thereof to investigate which representation is best in terms of speed and accuracy. We present our initial hypotheses, the outcome of the user studies, and recommendations regarding directed-edge visualization.
High-Dimensional Chaotic and Attractor Systems
Authors: Vladimir G. Ivancevic
Venue: Intelligent Systems, Control And Automation: Science And Engineering (2007)

This - is a graduatelevel monographic textbook devoted to understanding, prediction and control of highdimensional chaotic and attractor systems of real life. The objective of the book is to provide - the serious reader with a serious scientific tool that will enable the actual performance of competitive research in highdimensional chaotic and attractor dynamics. The book has nine Chapters. The first Chapter gives a textbook-like introduction into the low-dimensional attractors and chaos. This Chapter has an inspirational character, similar to other books on nonlinear dynamics and deterministic chaos. The second Chapter deals with Smales topological transformations of stretching, squeezing and folding (of the systems phasespace), developed for the purpose of chaos theory. The third Chapter is devoted to Poincars 3-body problem and basic techniques of chaos control, mostly of Ott-Grebogi-Yorke type. The fourth Chapter is a review of both Landaus and topological phase transition theory, as well as Hakens synergetics. The fifth Chapter deals with phase synchronization in high-dimensional chaotic systems. The sixth Chapter presents high-tech Josephson junctions, the basic components for the future quantum computers. The seventh Chapter deals with fractals and fractional Hamiltonian dynamics. The 8th Chapter gives a review of modern techniques for dealing with turbulence, ranging from theparameterspace of the Lorenz attractor to the Lie symmetries. The last, 9th, Chapter attempts to give a brief on the cutting edge techniques of the high-dimensional nonlinear dynamics (including geometries, gauges and solitons, culminating into the chaos field theory).
Visual attention in spoken human-robot interaction
Authors: Maria Staudte, Matthew W. Crocker
Venue: Proceedings of the 4th ACM/IEEE international conference on Human robot interaction (2009)

Psycholinguistic studies of situated language processing have revealed that gaze in the visual environment is tightly coupled with both spoken language comprehension and production. It has also been established that interlocutors monitor the gaze of their partners, a phenomenon called "joint attention", as a further means for facilitating mutual understanding. We hypothesise that human-robot interaction will benefit when the robot's language-related gaze behaviour is similar to that of people, potentially providing the user with valuable non-verbal information concerning the robot's intended message or the robot's successful understanding. We report findings from two eye-tracking experiments demonstrating (1) that human gaze is modulated by both the robot speech and gaze, and (2) that human comprehension of robot speech is improved when the robot's real-time gaze behaviour is similar to that of humans.
Maximum-Likelihood Estimator for Coarse Carrier Frequency Offset Estimation in OFDM Systems
Authors: Feng Yang, Zhenrong Zhang, Yifan Chen
Venue: Wireless Personal Communications: An International Journal (2009)

Orthogonal frequency division multiplexing (OFDM) systems are more sensitive to carrier frequency offset (CFO) compared to the conventional single carrier systems. CFO destroys the orthogonality among subcarriers, resulting in inter-carrier interference (ICI) and degrading system performance. To mitigate the effect of the CFO, it has to be estimated and compensated before the demodulation. The CFO can be divided into an integer part and a fractional part. In this paper, we investigate a maximum-likelihood estimator (MLE) for estimating the integer part of the CFO in OFDM systems, which requires only one OFDM block as the pilot symbols. To reduce the computational complexity of the MLE and improve the bandwidth efficiency, a suboptimum estimator (Sub MLE) is studied. Based on the hypothesis testing method, a threshold Sub MLE (T-Sub MLE) is proposed to further reduce the computational complexity. The performance analysis of the proposed T-Sub MLE is obtained and the analytical results match the simulation results well. Numerical results show that the proposed estimators are effective and reliable in both additive white Gaussian noise (AWGN) and frequency-selective fading channels in OFDM systems.
Optimization techniques for tuning heading controllers of an autonomous inscale fast-ferry model
Authors: Francisco J. Velasco, Elías Revestido, Eloy Lopez, Emiliano Moyano, M. Haro Casado
Venue: Proceedings of the 8th conference on Simulation, modelling and optimization (2008)

In the present paper, optimization techniques are used to tune heading controllers. Several simulations point out the improvement obtained with this short of techniques with respect to other. The heading control is based on a model obtained from data provided by a platform for marine vehicles. This platform has an in-scale fast-ferry model TF-120, which was developed to be autonomous and is controlled remotely from a PC using Wi-Fi communications. Different classical control structures for heading autopilot are studied and results obtained from optimization techniques are compared to genetic algorithm techniques.
Computational econometrics in an empirical investigation of the validity of CAPM in UK evidence
Authors: N. Loukeris
Venue: Proceedings of the 8th conference on Systems theory and scientific computation (2008)

The Capital Asset Pricing Model (CAPM) under the means of the two step regression procedure indicated that the cross section of average excess security return is positively related to beta. In a frame of Computational Econometrics the two step regression procedure being implemented in to CAPM, resulted that the strict CAPM test rejected the second H0 hypothesis for the market risk premium, hence the slope of the Security Market Line (SML) is different from the slope of SML indicated by CAPM. Consequently Financial Management is not statistical efficient in the CAPM framework.

Authors: Jumril Yunas, Azrul Azlan Hamzah, Burhanuddin Yeop Majlis
Venue: Microsystem Technologies (2009)

On-chip micro-transformer on high resistive glass substrate has been developed. The transformer consists of stacked spiral coil with square interwinding coil structure which is fabricated using surface micromachining technique. The performance of the micro-transformer is illustrated through low and high frequency measurements. The characteristics of glass based transformer are compared with conventional Si-based micro-transformer. The results show that the RF performance of the glass-based transformer is improved compared to that of silicon-based transformer. The process fabrication of the device is simple, highlighting a good prospect for the future three-dimensional RF-MEMS device application.
XRound: A reversible template language and its application in model-based security analysis
Authors: Howard Chivers, Richard F. Paige
Venue: Information and Software Technology (2009)

Successful analysis of the models used in Model-Driven Development requires the ability to synthesise the results of analysis and automatically integrate these results with the models themselves. This paper presents a reversible template language called XRound which supports round-trip transformations between models and the logic used to encode system properties. A template processor that supports the language is described, and the use of the template language is illustrated by its application in an analysis workbench, designed to support analysis of security properties of UML and MOF-based models. As a result of using reversible templates, it is possible to seamlessly and automatically integrate the results of a security analysis with a model.
On the (Im)Possibility of Arthur-Merlin Witness Hiding Protocols
Authors: Iftach Haitner, Alon Rosen, Ronen Shaltiel
Venue: Proceedings of the 6th Theory of Cryptography Conference on Theory of Cryptography (2009)

The concept of witness-hiding suggested by Feige and Shamir is a natural relaxation of zero-knowledge. In this paper we identify languages and distributions for which many known constant-round public-coin protocols with negligible soundness cannot be shown to be witness-hiding using black-box techniques. One particular consequence of our results is that parallel repetition of either 3-Colorability or Hamiltonicity cannot be shown to be witness hiding with respect to some probability distribution over the inputs assuming that: the distribution assigns positive probability only to instances with exactly one witness. Polynomial size circuits cannot find a witness with noticeable probability on a random input chosen according to the distribution. The proof of security relies on a black-box reduction that is independent of the choice of the commitment scheme used in the protocol. These impossibility results conceptually match results of Feige and Shamir that use such black-box reductions to show that parallel repetition of 3-Colorability or Hamiltonicity is witness-hiding for distributions with "two independent witnesses".We also consider black-box reductions for parallel repetition of 3-Colorability or Hamiltonicity that depend on a specific implementation of the commitment scheme. While we cannot rule out such reductions completely, we show that "natural reductions" cannot bypass the limitations above.Our proofs use techniques developed by Goldreich and Krawczyk for the case of zero knowledge. The setup of witness-hiding, however, presents new technical and conceptual difficulties that do not arise in the zero-knowledge setting. The high level idea is that if a black-box reduction establishes the witness-hiding property for a protocol, and the protocol also happens to be a proof of knowledge, then this latter property can be actually used "against the reduction" to find witnesses unconditionally.
Upper bounds for parent-identifying set systems
Authors: Michael J. Collins
Venue: Designs, Codes and Cryptography (2009)

Incremental data-driven learning of a novelty detection model for one-class classification with application to high-dimensional noisy data
Authors: Randa Kassab, Frédéric Alexandre
Venue: Machine Learning (2009)

Most conventional learning algorithms require both positive and negative training data for achieving accurate classification results. However, the problem of learning classifiers from only positive data arises in many applications where negative data are too costly, difficult to obtain, or not available at all. This paper describes a new machine learning approach, called ILoNDF (Incremental data-driven Learning of Novelty Detector Filter). The approach is inspired by novelty detection theory and its learning method, which typically requires only examples from one class to learn a model. One advantage of ILoNDF is the ability of its generative learning to capture the intrinsic characteristics of the training data by continuously integrating the information relating to the relative frequencies of the features of training data and their co-occurrence dependencies. This makes ILoNDF rather stable and less sensitive to noisy features which may be present in the representation of the positive data. In addition, ILoNDF does not require extensive computational resources since it operates on-line without repeated training, and no parameters need to be tuned. In this study we mainly focus on the robustness of ILoNDF in dealing with high-dimensional noisy data and we investigate the variation of its performance depending on the amount of data available for training. To make our study comparable to previous studies, we investigate four common methods: PCA residuals, Hotelling's T 2 test, an auto-associative neural network, and a one-class version of the SVM classifier (lately a favored method for one-class classification). Experiments are conducted on two real-world text corpora: Reuters and WebKB. Results show that ILoNDF tends to be more robust, is less affected by initial settings, and consistently outperforms the other methods.

Authors: Li-Yang Shao, Xinyong Dong, Hwa-Yaw Tam
Venue: Proceedings of the 2008 International Conference on Advanced Infocomm Technology (2008)

We propose and demonstrate a novel scheme for discrimination of strain and temperature using a dual polarization distributed Bragg reflector (DBR) fiber laser. By measuring the mean wavelength as well as the polarization beat frequency of the output of the fiber laser, strain and temperature can be determined simultaneously. Experimental results show that the sensor has an accuracy of &plusmn;9.5&mu;&epsilon; and &plusmn;0.05.
Global satellite communications technology and systems
Authors: Alfred U. Mac Rae, Joseph N. Pelton, Ramon De Paula
Venue: Space Communications (2000)

This special issue of Space Communications contains nine papers derived from a study, &lsquo;Global satellite communications technology and systems&rsquo;, sponsored by NASA and the NSF. The purpose of this study was to compare the position of the US in commercial satellite communications technology, research, development and markets with that of the rest of the world. It included visits to over 65 satellite manufacturers, service providers and R&D Institutes located in North and South America, Europe, Asia and Africa. These papers include overviews and country by country material on R&D activities, technology status, markets and trends from this study. The conclusions of this panel indicate that the US continues to have a strong presence in this large and rapidly growing global industry but that European and Asian entities are making significant investments in their manufacturing and R&D activities and are becoming major participants in this satellite communications industry. The migration of US aerospace corporations from being primarily manufacturers of spacecraft to being primarily satellite service providers could serve to undercut necessary longer term R&D to develop new technologies.

Authors: Hongqi Xiang, Xing Jiang, Simin Li
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 01 (2009)

Aperture coupling feed and double-layer microstrip patch structure are applied to design microstrip antenna element and subarrays of microstrip antenna array with high gain low sidelobe and backlobe at Ku-band. Parallel feed and T-junction type power divider are used to design low sidelobe array by the principle of Dolph-Chebeshev distribution. The simulate results show that the relative bandwidth of the element (VSWR 1.5) reaches 25.6%. From the measurement results of subarray: the operational bandwidth (VSWR 1.5) are not less than 0.96GHz and the gain are about 24dB, which are in good agreement with the simulate results. The 256 elements microstrip antenna array with sidelobe in E-plain is simulated.
Video-Based Modeling of Dynamic Hair
Authors: Tatsuhisa Yamaguchi, Bennett Wilburn, Eyal Ofek
Venue: Proceedings of the 3rd Pacific Rim Symposium on Advances in Image and Video Technology (2009)

We present a method for creating realistic hair animation models based on videos of real hair in motion. We use an array of synchronized cameras to capture dynamic hairstyles. The hair structure and motion is modeled using an algorithm that grows each hair in segments from the root to the tip. Our algorithm generates hairs that are consistent with hair orientations observed in the input images and also enforces temporal smoothness constraints on the shape of the hair from frame to frame. Examples of synthesized hair models show the effectiveness of the method.
