Type-1 and type-2 fuzzy inference systems as integration methods in modular neural networks for multimodal biometry and its optimization with genetic algorithms
Authors: Denisse Hidalgo, Oscar Castillo, Patricia Melin
Venue: Information Sciences: an International Journal (2009)

We describe in this paper a comparative study between fuzzy inference systems as methods of integration in modular neural networks for multimodal biometry. These methods of integration are based on techniques of type-1 fuzzy logic and type-2 fuzzy logic. Also, the fuzzy systems are optimized with simple genetic algorithms with the goal of having optimized versions of both types of fuzzy systems. First, we considered the use of type-1 fuzzy logic and later the approach with type-2 fuzzy logic. The fuzzy systems were developed using genetic algorithms to handle fuzzy inference systems with different membership functions, like the triangular, trapezoidal and Gaussian; since these algorithms can generate fuzzy systems automatically. Then the response integration of the modular neural network was tested with the optimized fuzzy systems of integration. The comparative study of the type-1 and type-2 fuzzy inference systems was made to observe the behavior of the two different integration methods for modular neural networks for multimodal biometry.
Heterogeneous Payoffs and Social Diversity in the Spatial Prisoner's Dilemma game
Authors: Golriz Rezaei, Michael Kirley
Venue: Proceedings of the 7th International Conference on Simulated Evolution and Learning (2008)

In this paper, we investigate the role of heterogeneous payoff values and social diversity in a spatial version of the iterated prisoner's dilemma game. Typically, a fixed number of agents play the game over a specified number of rounds. At each time step, the agents receive a fixed reward based on the strategy they have adopted and the corresponding payoff (or reward) matrix. We argue that such restrictions are unlikely to be fulfilled in real-life situations. Subsequently, we introduce additional features into the game. Here, each agent has an additional age attribute that can be used to control the number of iterations of the game an agent actually participates in. We also introduce dynamic payoff values that are correlated with particular agent experience levels. Numerical simulations show that the proposed heterogeneous agent model promotes the evolution of cooperation in some circumstances.
A Tree Distance Function Based on Multi-sets

Venue: New Frontiers in Applied Data Mining: PAKDD 2008 International Workshops, Osaka, Japan, May 20-23, 2008. Revised Selected Papers (2009)

We introduce a tree distance function based on multi-sets. We show that this function is a metric on tree spaces, and we design an algorithm to compute the distance between trees of size at most n in O(n 2) time and O(n) space. Contrary to other tree distance functions that require expensive memory allocations to maintain dynamic programming tables of forests, our function can be implemented over simple and static structures. Additionally, we present a case study in which we compare our function with other two distance functions.
Interactive multi-user multimedia environments on the Internet: an overview of DAMSEL and its implementation
Venue: Proceedings of the 1996 International Conference on Multimedia Computing and Systems (1996)

Abstract: The paper presents an overview of DAMSEL and it's implementation. DAMSEL comprises an embeddable dynamic multimedia specification language, and a software architecture suitable for multi user interactive multimedia environments. The goal of DAMSEL is to explore language constructs and execution environments for next generation interactive multimedia applications. The constructs of DAMSEL include primitives for event driven temporal specification-supporting causation and inhibition. Specifications allow behavioral parameters to be chosen, enabling very powerful temporal relations to be defined. Other constructs support the modification, and analysis of multimedia data, and high level abstractions for connections to user interfaces. Further, DAMSEL constructs support conditional and constraint logics, enabling more complex specifications than currently possible. DAMSEL is being implemented using a java implementation of the CORBA standard.
Multi-camera people tracking using evidential filters
Authors: Rafael Muòoz-Salinas, R. Medina-Carnicer, F. J. Madrid-Cuevas, A. Carmona-Poyato
Venue: International Journal of Approximate Reasoning (2009)

This work proposes a novel filtering algorithm that constitutes an extension of Bayesian particle filters to the Dempster-Shafer theory. Our proposal solves the multi-target problem by combining evidences from multiple heterogeneous and unreliable sensors. The modelling of uncertainty and absence of knowledge in our approach is specially attractive since it does not require to specify prior nor conditionals that might be difficult to obtain in complex problems. The algorithm is employed to propose a novel solution to the multi-camera people tracking problem in indoor environments. For each particle, the evidence of finding the person being tracked at the particle location is calculated by each sensor. Sensors also provide a degree of evidence about their reliability. The reliability is calculated based on the visible portion of the targets and their occlusions. Evidences collected from the camera set are fused considering their reliability to calculate the best hypothesis. The experiments conducted in several environments show the validity of the proposal.
New synchronization schemes for UWB systems
Authors: Dahae Chong, Sangho Ahn, Youngpo Lee, Seokho Yoon
Venue: Proceedings of the 3rd International Conference on Ubiquitous Information Management and Communication (2009)

This paper addresses the decision rules for synchronization in ultra-wideband (UWB) systems. The conventional decision rule cannot guarantee a good performance in receiver operations such as detection and decoding after the synchronization. To solve this problem, in this paper, we propose new decision rules for synchronization in UWB systems. We first derive an optimal decision rule based on the maximum likelihood (ML) criterion and then a simpler suboptimal decision rule. Simulation results show that the proposed decision rules have better synchronization performance than the conventional decision rule.
Improved Two-Level Model Averaging Techniques in Drosophila Brain Modeling
Authors: Cheng-Chi Wu, Chao-Yu Chen, Hsiu-Ming Chang, Ann-Shyn Chiang, Yung-Chang Chen
Venue: Proceedings of the 3rd Pacific Rim Symposium on Advances in Image and Video Technology (2009)

Two-level model averaging techniques have been proposed to construct the 3D reference template for the Drosophila brain. The surface-based reference template is suitable for integration of experimental data from different laboratories. The 3D distance transform is the most memory and time consuming part in the model averaging algorithm. With the improvement of microscopic scanning technology, images of higher resolution can be acquired. Thus, the memories required for 3D distance transform become critical. In this paper, improved two-level model averaging techniques are proposed with three improvements. A two-scale distance map creation algorithm is introduced to reduce the memory cost in the distance transform. The computational time is reduced by a reduction of computation points in the distance map creation. The third improvement is an outlier rejection module to improve the robustness of the resulting average model.
The RISC ProofNavigator: a proving assistant for program verification in the classroom
Authors: Wolfgang Schreiner
Venue: Formal Aspects of Computing (2009)

This paper gives an overview of the RISC ProofNavigator, an interactive proving assistant for the area of program verification. The assistant combines the user-guided top-down decomposition of proofs with the automatic simplification and closing of proof states by an external satisfiability solver. The software exhibits a modern graphical user interface which has been developed with a focus on simplicity in order to make the software suitable for educational scenarios. Nevertheless, some use cases of a certain level of complexity demonstrate that it may be also appropriate for various realistic applications.
Properties of relationships and their representation
Authors: Ramez El-Masri, Gio Wiederhold
Venue: Proceedings of the May 19-22, 1980, national computer conference (1980)

Data models can provide powerful abstractions to aid in the design of data structures that are relevant to database systems. A large amount of effort has been expended in the development of suitable data models. Several of these models distinguish between classes of entities and relationships among classes of entities in the abstractions they use for modelling the data. Among these models are the network model, Schmid and Swenson's model, the entity-relationship model, Navathe and Schkolnick's model, the semantic data model, and the structural model.
Simultaneous shield and repeater insertion
Authors: Renatas Jakushokas, Eby G. Friedman
Venue: Proceedings of the 19th ACM Great Lakes symposium on VLSI (2009)

Resource based optimization for high performance integrated circuits is presented. The methodology is applied to simultaneous shield and repeater insertion, resulting in minimum coupling noise under power, delay, and area constraints. Design expressions exhibiting parabolic noise behavior are compared with SPICE simulations. Due to the parabolic coupled noise behavior, the minimum noise is established. Good agreement between the analytic results and SPICE simulations is shown.

RBM: A Role Based Mobility Model for VANET
Authors: Jingxuan Wang, Wei Yan
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 02 (2009)

Simulation is an important approach to evaluate protocols. Realistic simulations lead to accurate evaluations. However, most of evaluations in VANET recently were still using MANET mobility models or MANET models with a map bounder. Existing VANET mobility models, which treat all nodes identical, cannot reach most researchers' demand. In this paper, we develop a role based mobility model for VANET. On contrast to existing models, nodes are differentiated by their roles. And nodes playing different roles have different strategy on both macro and micro mobility scope. Simulation shows that this new model are more realistic than existing models and can lead to many daily traffic situations that is easily observed in real life.
Analysis of Emotional Gestures for the Generation of Expressive Copying Behaviour in an Embodied Agent
Authors: Ginevra Castellano, Maurizio Mancini
Venue: Gesture-Based Human-Computer Interaction and Simulation: 7th International Gesture Workshop, GW 2007, Lisbon, Portugal, May 23-25, 2007, Revised Selected Papers (2009)

This paper presents a system capable of acquiring input from a video camera, processing information related to the expressivity of human movement and generating expressive copying behaviour of an Embodied Agent. We model a bi-directional communication between user and agent based on real-time analysis of movement expressivity and generation of expressive copying behaviour: while the user is moving, the agent responds with a gesture that exhibits the same expressive characteristics. An evaluation study based on a perceptual experiment with participants showed the effectiveness of the designed interaction.
Detecting Inconsistencies in Large Biological Networks with Answer Set Programming
Authors: Martin Gebser, Torsten Schaub, Sven Thiele, Björn Usadel, Philippe Veber
Venue: Proceedings of the 24th International Conference on Logic Programming (2008)

We introduce an approach to detecting inconsistencies in large biological networks by using Answer Set Programming. To this end, we build upon a recently proposed notion of consistency between biochemical/genetic reactions and high-throughput profiles of cell activity. We then present an approach based on Answer Set Programming to check the consistency of large-scale data sets. Moreover, we extend this methodology to provide explanations for inconsistencies in the data by determining minimal representations of conflicts. In practice, this can be used to identify unreliable data or to indicate missing reactions.
Exploiting a buffer overflow using metasploit framework
Authors: Mustapha Refai
Venue: Proceedings of the 2006 International Conference on Privacy, Security and Trust: Bridge the Gap Between PST Technologies and Business Services (2006)

Buffer overflow has been used for many years as an effective mean for system penetration to gain remote access [2, 3, 5, 6, 7]. Buffer overflow exploitation takes advantage of weak software programming such as boundary check for memory usage of declared buffers somewhere in the program to undermine software security and exploit its vulnerability so that attacker can remotely access victim's system. This access can be then escalated either vertical, to gain administrator privilege (in case of windows operating system, or root access, in case UNIX like operating system), or horizontal to access other host in the same network. This paper will try to address the question of, what buffer overflow is. How it happens? How it can be exploited? And what are the defense measures that can be taken to avoid such a problem? As a response to the above questions, a discussion about available commercial and open source software that are used as tools for exploitation are covered. The widely used open source software called Metasploit Framework is used to demonstrate the concept.

Authors: Luis Gutierrez, Sebastih Sallent
Venue: Proceedings of the 1999 IEEE International Conference on Multimedia Computing and Systems - Volume 02 (1999)

Multimedia truftic is curried over Multi-Access Channels using Random Multi-Access Protocols (RMAP's) as the method to access to the common channel by users equipment's, The main goal of any RMAP is that the network be shared by all users in a fair way, RMAP's must also be able to cope with the Q.oS. that different multimedia traffics ask for. Current protocols proposed for multimedia traffic are very sophisticated and difficult to analyze because they use distributed queues. The main goal of this paper is to present a common methodology to analyze multimedia RMAP's, the results obtained by this procedure include the computation not only of the expected values but the distributions of the final interdeparture time and the departure burst size.
Smart metering demand management programs: challenging the comfort and cleanliness habitus of households
Authors: Yolande Strengers
Venue: Proceedings of the 20th Australasian Conference on Computer-Human Interaction: Designing for Habitus and Habitat (2008)

Drawing on Pierre Bourdieu's concepts of habitus, field and capital, this paper outlines how smart metering demand management programs could be redesigned to bring together the competing fields of resource management and domestic life. Comfort and cleanliness expectations, which are ingrained in the habitus of householders and the field of domestic life, are often overlooked in demand management programs, which focus instead on making existing and evolving expectations more efficient. This paper draws on preliminary findings from qualitative research activities with householders who received consumption feedback through an in-home display, and/or variable price signals --- both enabled by smart meters. The paper offers insights for designers of interactive demand management strategies about how to go beyond achieving efficiency benefits in the home in order to fundamentally change expectations and norms ingrained in the habitus.

Robust Audio Zero-Watermark Based on LWT and Chaotic Modulation
Authors: Rangding Wang, Wenji Hu
Venue: Proceedings of the 6th International Workshop on Digital Watermarking (2008)

A robust audio zero-watermark scheme which constructed the watermark in lifting wavelet domain based on chaotic modulation is presented in this paper. Since the constructed zero-watermark is not embedded into the original audio indeed, the contradiction between imperceptibility and robustness is perfectly solved. The algorithm based on coefficient maximization guarantees that the zero-watermark which constructed by low frequency coefficients represents the significant characteristics of the audio signal, experiment results show that it is robust against general audio processing such as noise addition, low-pass filtering, requantization, resampling and mp3 compression. And after the watermark is created, an initial vector is obtained by chaotic modulation, so the storage space is reduced after generating the watermark.
Brief paper: Adaptive quantized control for linear uncertain discrete-time systems
Authors: Tomohisa Hayakawa, Hideaki Ishii, Koji Tsumura
Venue: Automatica (Journal of IFAC) (2009)

A direct adaptive control framework for linear uncertain systems for using communication channels is developed. Specifically, the control signals are to be quantized and sent over a communication channel to the actuator. The proposed framework is Lyapunov-based and guarantees partial asymptotic stability, that is, Lyapunov stability of the closed-loop system states and attraction with respect to the plant states. The quantizers are logarithmic and characterized by sector-bound conditions, with the conic sectors adjusted at each time instant by the adaptive controller, in conjunction with the system response. Furthermore, we extend the scheme to the case where the logarithmic quantizer has a deadzone around the origin so that only a finite number of quantization levels is required to achieve practical stability. Finally, a numerical example is provided to demonstrate the efficacy of the proposed approach.

Authors: Masato Noda, Toshihiro Osumi, Kenta Fujimoto, Yuki Kuwayama, Hirotaka Osawa, Michita Imai, Kazuhiko Shinozawa
Venue: Proceedings of the 4th ACM/IEEE international conference on Human robot interaction (2009)

We propose a portable robot named "Blog Robot" which presents blog contents by using verbal and non-verbal expression. Blog Robot is a robotized smart-phone which has a head and arms for making hand gestures, eye contact, and joint attention. The blog is widely used to express personal views or to record daily occurrences. One of the information frequently posted on the blog is related to a certain place such as a tourist site or a shop. Meanwhile, people sit down in front of their PC and check blogs through the text and the image displayed on the Web browser. However, their style of checking the blogs is not good way for them to realize the authentic situations which blog writers let them know. The user carries Blog Robot like cellular phone and can browse blogs related to the location where user is. The browse method makes the user access the blog at the real scene related to the contents of the blog. Blog Robot gives her/him the content of the blog by reading it with synthesized speech. In particular, the nonverbal information generated by Blog Robot enhances the read information as if the blog writer is next her/him while telling her/him it. The browse method is expected to enable the user to obtain more realistic information than the Web browser on the PC. Moreover, it enables the user shares the information with the blog writer. In addition, since the browse through Blog Robot is performed at the location that the blog writer once visited, the blog writer has proper feedback from the user. It is difficult for the blog writer to obtain the same feedback from the user who sits in front of her/his PC because she/he is not there. We have also designed tags specific to generating the nonverbal expression of Blog Robot and the tags are embedded within the text in the blog. The tags can be used not only for Blog Robot but also for the PC. If the user checks the blog including the tags, they are displayed as icon on the Web browser.
