Authors: Jin Tian, Guangguo Bi, H. Tianfield
Venue: Proceeding of the 2005 conference on Self-Organization and Autonomic Informatics (I) (2005)

The rapid development of mobile and wireless communication technologies requires that wireless devices should support voice, video, and data communications and should flexibly access IP based core networks. This paper proposes a new wireless module architecture for the next generation wireless networks and discusses its access methods based on access bridge point. In addition, the protocols for accessing IP based core networks are discussed for the proposed access network architecture.
A fuzzy rule-based modeling of the Sociology of Organized Action
Authors: Sandra Sandri, Christophe Sibertin-Blanc
Venue: Proceeding of the 2007 conference on Artificial Intelligence Research and Development (2007)

In this work, we address the modeling of the Sociology of Organized Action in a fuzzy rule-based environment. We also discuss some game concepts such as Pareto optima in such a framework. We illustrate our approach with an example from the sociology literature.
Multiagent reinforcement learning: algorithm converging to Nash equilibrium in general-sum discounted stochastic games
Authors: Natalia Akchurina
Venue: Proceedings of The 8th International Conference on Autonomous Agents and Multiagent Systems - Volume 2 (2009)

This paper introduces a multiagent reinforcement learning algorithm that converges with a given accuracy to stationary Nash equilibria in general-sum discounted stochastic games. Under some assumptions we formally prove its convergence to Nash equilibrium in self-play. We claim that it is the first algorithm that converges to stationary Nash equilibrium in the general case.
Towards A Realism-Based Metric for Quality Assurance in Ontology Matching
Authors: Werner Ceusters
Venue: Proceeding of the 2006 conference on Formal Ontology in Information Systems: Proceedings of the Fourth International Conference (FOIS 2006) (2006)

Ontology matching is commonly defined as a matter of dealing with semantic correspondences between terms in ontologies and thus refers to more specific activities such as mapping or aligning, possibly with ontology merging in mind. However, it has been pointed out that there still prevails no common understanding of what such 'semantic correspondences' are supposed to be, and that in consequence “human experts do not agree on how ontologies should be merged, and we do not yet have a good enough metric for comparing ontologies.” In what follows we define such a metric, which is designed to allow assessment of the degree to which the integration of two ontologies yields improvements over either of the input ontologies. We start out from the thesis that if two or more ontologies are to be considered for matching, then, however much they may reflect distinct views of reality on the part of their authors, the portions of reality to which they refer must be such as to overlap. Our approach takes account of the fact that both authors and users of ontologies may make mistakes (the former in their interpretation of reality and in the formulation of their views, the latter in misinterpreting the former's intentions).To do justice to such factors, we need to draw a distinction between three levels of: (1) reality; (2) cognitive representations; and (3) publicly accessible concretizations of these representations. We can then define 'semantic correspondence' not, as is usual, in terms of (horizontal) relations of 'association' or 'synonymy' between the terms within the ontologies to be matched, but rather in terms of the (vertical) relation of reference: terms correspond semantically if they refer to the same entities in reality. One conclusion of our argument is that, when ontology matching has been used as the first step towards ontology merging, then the merged ontology can contain inconsistencies only if there are already inconsistencies in at least one of the source ontologies.
Compositing Visual Effects: Essentials for the Aspiring Artist
Authors: Steve Wright
Venue:  (2007)

Put the essential concepts and techniques of digital compositing to work for you without the need of a single mathematical equation. Compositing Visual Effects is lavishly illustrated with hundreds of film shots, figures, illustrations and diagrams to help the visual reader gain a valuable vocabulary and understanding of the full range of visual effects, in which digital compositing plays a key role.Beginning with an inspirational tour of the scope and magnitude of digital compositing you get a solid overview of the kinds of digital effects routinely executed today. See how CGI (Computer Generated Image) is composited with live action, how set extensions are done, and what a match-move shot is. Following that, you learn each of the key applications of digital compositing, which include bluescreen compositing, bullet time shots, motion tracking, and rotoscoping, and you get a primer on digital images, key concepts, and terms used in the compositing process. The subsequent chapters dig down into each of the major digital compositing applications, introducing the fundamental concepts and processes behind them. This includes the many ways to composite CGI, bluescreen compositing, animation, creating masks, working with digital keyers, and many more; but most importantly, the art of digital compositing-making your shots look not just photorealistic, but cool.Learn what is easy and hard, possible and impossible, and what to expect when working on a job that entails digital compositing. There are tips on when not to use the new low-end DV video cameras and tips for the client, such as guidelines on how to shoot a quality bluescreen or greenscreen to get the best results at compositing time. All the while, special attention is paid to defining new terminology and telling a clear story from the ground up, with the only requirement being that you have read the previous chapters. * An accessible introduction to a complex subject for novice compositors* Full color presentation illustrating the art and techniques of the practice* An experienced book author of 20 years compositing experience; with 60 feature film credits including Vanilla Sky, X-Men 2, Swept Away, and Solaris The ACM Portal is published by the Association for Computing Machinery.

Shallow Semantic Parsing Based on FrameNet, VerbNet and PropBank
Authors: Ana-Maria Giuglea, Alessandro Moschitti
Venue: Proceeding of the 2006 conference on ECAI 2006: 17th European Conference on Artificial Intelligence August 29 -- September 1, 2006, Riva del Garda, Italy (2006)

This article describes a semantic parser based on FrameNet semantic roles that uses a broad knowledge base created by interconnecting three major resources: FrameNet, VerbNet and PropBank. We link the above resources through a mapping between Intersective Levin classes, which are part of PropBank's annotation, and the FrameNet frames. By using Levin classes, we successfully detect FrameNet semantic roles without relying on the frame information. At the same time, the combined usage of the above resources increases the verb coverage and confers more robustness to our parser. The experiments with Support Vector Machines on automatic Levin class detection suggest that (a) tree kernels are well suited for the task and (b) Intersective Levin classes can be used to improve the accuracy of semantic parsing based on FrameNet roles.
Wolap: wavelet-based on-line analytical processing
Authors: Cyrus Shahabi
Venue:  (2008)

Wavelet Transform has emerged as an elegant tool for online analytical queries. Most of the methods using wavelets, however, share the disadvantage of providing only data-dependant approximate answers by compressing the data. On the contrary, we propose a wavelet-based query processing technique, WOLAP, which does not require compressing the data. Instead, we employ wavelet transform to compact incoming queries rather than the underlying data. The intuition here is that queries are well-formed with repetitive patterns that can be exploited by wavelets for a more effective compression, leading to efficient query performance. WOLAP extends the set of ad-hoc analytical queries to include the entire family of range polynomial aggregate queries as well as the complex class of range group-by queries. In addition, leveraging from the multi-resolution property of wavelets, WOLAP supports progressive and approximate query processing in case of time or space limitation. Toward realizing the practical use of WOLAP, we provide a framework to efficiently maintain large multidimensional wavelet-transformed data. In particular, by introducing two novel operations which work directly in the wavelet domain, we allow WOLAP to transform, reconstruct, store, update, and append data in an I/O efficient manner. By developing a real system and conducting extensive sets of experiments with several real-world datasets, we have verified the effectiveness of WOLAP in practice.
Language design for distributed objects
Authors: William R. Cook, Eli Tilevich, Ali Ibrahim, Ben Wiedermann
Venue: Proceedings of the 1st International Workshop on Distributed Objects for the 21st Century (2009)

The fundamental ideas of distributed objects have changed little in the last 20 years. Existing languages are retrofitted with transparent distribution mechanisms based on proxies. Experiments with mobile code demonstrate its power but have little impact on practice. The problems with transparency and mobile code have been well known since at least 1994. But in the absence of any fundamental new ideas, the same problematic approaches are used, for example in the design of Java RMI. In this essay we discuss a new programming construct called Remote Batch Invocation (RBI). A batch is a code block that combines remote and local execution over fine-grained object interfaces, but is executed by partitioning and remote evaluation. Remote Batch Invocation effectively addresses the shortcomings of transparent distribution with a controlled form of mobile code. Our experience leads us to believe that distribution cannot be implemented as a library, but requires specific language support. Viewing distribution as a language design problem represents a revolutionary step in the development of distributed objects.
Improving ACK reply of DSR protocol for mobile ad hoc network
Authors: Qi Han, Abdullah Gani, Nor Badrul Anuar, Omar Zakaria
Venue: Proceedings of the 8th WSEAS international conference on Electronics, hardware, wireless and optical communication (2009)

In this paper, we present our technique to improve the performance of DSR protocol by using ACK reply path as a backup route when an original route fails in Mobile Ad Hoc networks. In the traditional DSR, when the route is no longer in use, a backup route will be initiated to transfer data in route cache. However, if the backup route is also failed, it will affect the overall network performance. We modify the DSR so-called as Modified DSR protocol (MDSR) so that the source node can still receive ACK reply from destination node when an original route is broken, which means data packets can be transferred along with the ACK path. MDSR deploys the idea of TCP-BuS to solve unnecessary resending of lost data packets. We implement and perform our proposed model in NS2 and the results show that the performance of modified DSR is better than the traditional DSR protocol in End to End delay, packet delivery ratio and routing load.
Cloud security technologies
Authors: Igor Muttik, Chris Barton
Venue: Information Security Tech. Report (2009)

You may have heard a new term that started making rounds very recently - ''cloud-based security''. In this paper we describe past and contemporary security technologies based on the knowledge provided from the servers in the Internet ''cloud''. We discuss how cloud-based malware scanners can simbiotically coexist with traditional scanning technologies, what are the advantages and limitations of the new approach. We also touch on the privacy aspects and challenges related to testing (especially comparative testing) of the cloud security solutions.
Peer-to-peer videoconferencing with H.264 software codec for mobiles
Authors: Hans L. Cycon, Thomas C. Schmidt, Gabriel Hege, Matthias Waahlisch, Detlev Marpe, Mark Palkow
Venue: Proceedings of the 2008 International Symposium on a World of Wireless, Mobile and Multimedia Networks (2008)

A rapidly growing number of carriers offer wireless video services to their customers, taking advantage of high quality video codecs implemented in dedicated hardware of selected mobile devices. In this paper we introduce a video conferencing software, which seamlessly integrates mobile with stationary users in a provider and device independent fashion. Innovations of this work are twofold. At first we report on a mobile realization of an H.264 video codec and its performance on a standard consumer Smartphone. Operating within the tight bounds of real-time compliance on mobiles, this software is an adapted version of a highly optimized H.264 codec. This DAVC codec, which we introduce along the line, significantly out-performs compatible H.264 realizations and allows for a scalable adaptation of its frame rate. In the second part we present a barrier-resistant peer-to-peer group communication scheme, which scales well for medium-size conferences and accounts for the heterogeneous nature of mobile and stationary participants. An outlook on mobility related group communication issues and future optimizations based on structured communication layers concludes the work.

A Proposal for a User Oriented Language Based on the Lyee Theory
Authors: Keizo Yamada, Jun Sasaki, Michiru Tanaka, Yutaka Funyu
Venue: Proceeding of the 2009 conference on Information Modelling and Knowledge Bases XX (2009)

In recent years, a problem has arisen in that users have become estranged from the processes of software development. End user development (EUD) is a solution to this problem. To realize EUD, however, we need to be able to describe the requirements of a user directly as a program. In this paper, we propose a declarative language based on the Lyee theory for programming environments for users. Using our language, we describe a program based on subject-based programming in Lyee theory. The program is then executed iteratively.
Development of an fpga based autopilot hardware platform for research and development of autonomous sytems
Authors: Wilfrido Moreno, Kimon Valavanis
Venue:  (2008)

Unmanned vehicles, both ground and aerial, have become prevalent in recent years. The research community has different needs than the industrial community when designing a finalized unmanned system since the vehicle, the sensors and the control design are dynamic and change frequently as new ideas are developed and implemented. Current autopilot hardware, which is available as on-the-market products and proposed in research, is sufficient for unmanned systems design. However, this equipment falls short of being able to accommodate the needs of those in the research community who must be able to quickly implement new ideas on a flexible platform. The contribution of this research is the realization of a hardware platform, which provides for rapid implementation of newly developed theory. Rapid implementation is gained by providing for software development from within the Simulink environment and utilizing previously unrealized flexibility in sensor selection. In addition to the development of the hardware platform, research was performed within Simulink&rsquo;s System Generator environment in order to complement the hardware. The software produced consists of a user template that integrates to the selected hardware. The template creates a user friendly environment, which provides the end user the capability to develop software algorithms from within the Simulink environment. This capability facilitates the final step of full hardware implementation. The major novelty of the research was the overall FPGA based autopilot design. The approach provided flexibility, functionality and generality. The approach is also suitable for and applicable to the design of multiple platforms. This research yielded a first time approach to the development of an unmanned systems autopilot platform by utilizing: (1) Development of programmable voltage level digital Input/Output (I/O), ports, (2) Utilization of Field Programmable Analog Arrays (FPAA), (3) Hardware capabilities to allow for integration with full computer systems, (4) A full Field Programmable Gate Array (FPGA), implementation, (5) Full integration of the hardware within Simulink&rsquo;s System Generator Toolbox.
A directory service for perspective access networks
Authors: Geoffrey Goodell, Mema Roussopoulos, Scott Bradner
Venue: IEEE/ACM Transactions on Networking (TON) (2009)

Network fragmentation occurs when the accessibility of a network-based resource to an observer is a function of how the observer is connected to the network. In the context of the Internet, network fragmentation is well known and occurs in many situations, including an increasing preponderance of network address translation, firewalls, and virtual private networks. Recently, however, new threats to Internet consistency have received media attention. Alternative namespaces have emerged as the result of formal objections to the process by which Internet names and addresses are provisioned. In addition, various governments and service providers around the world have deployed network technology that (accidentally or intentionally) restricts access to certain Internet content. Combined with the aforementioned sources of fragmentation, these new concerns provide ample motivation for a network that allows users the ability to specify not only the network location of Internet resources they want to view but also the perspectives from which they want to view them. Our vision of a perspective access network (PAN) is a peer-to-peer overlay network that incorporates routing and directory services that allow network perspective-sharing and nonhierarchical organization of the Internet. In this paper, we present the design, implementation, and evaluation of a directory service for such networks. We demonstrate its feasibility and efficacy using measurements from a test deployment on PlanetLab.
On the Design of Bio-inspired Multi-agent Systems for Coordination and Control
Authors: Paul Valckenaers
Venue: Proceeding of the 2005 conference on Artificial Intelligence Research and Development (2005)

The first part of the presentation surveys fundamental insights in the 'science of the artificial' as coined by the Herbert Simon. From these insights a number of design requirements and principles for complex adaptive man-invented systems are derived. The second part discusses a multi-agent coordination and control system answering the above requirements for a specific application domain. The system design is inspired by the behavior of social insects (ant colonies) and includes some 'social engineering' of the agent society. The discussion focuses on the society of the agents: its architecture, structure and interaction mechanisms; the internal architecture of a single agent is not discussed. This sample MAS design is computationally efficient and gives its user full control over the computation and communication effort where the result is 'best effort' only. These coordination and control systems handle a going concern; they do not limit themselves to one-shot problem solving.
Building and Evaluation of a Semantic Web System that Provides Teachers with Lesson Plans
Authors: Toshinobu Kasai, Haruhisa Yamaguchi, Kazuo Nagano, Riichiro Mizoguchi
Venue: Proceeding of the 2006 conference on Learning by Effective Utilization of Technologies: Facilitating Intercultural Understanding (2006)

In Japan, the “Period of Integrated Study” program began in elementary and secondary education in 2002. The “Period of Integrated Study” program emphasizes cultivating the ability to solve various problems in society. Most goals of this program involve meta-ability, which cannot be fully learned by traditional Japanese instructional methods. For this reason, it is necessary and important to provide instructors with a powerful help system that can locate and provide access to a variety of useful information resources. To this end, we have proposed a framework that reconstructs the resources according to various viewpoints based on Semantic Web technology. Further, we proposed a Goal Transition Model to show a skeleton of the transition of instructional goals based on ontologies and built a system that provides teachers with lesson plans effectively by applying this Model. In this paper, we describe support functions of this system and report results of an experiment carried out for evaluation of the functions.
Modelling the financial risk associated with U.S. movie box office earnings
Authors: Guang Bi, David E. Giles
Venue: Mathematics and Computers in Simulation (2009)

In this paper we use extreme value theory to model the U.S. movie box office returns, using weekly data for the period January 1982 to September 2006. The Peak over Threshold method is used to fit the Generalized Pareto distribution to the tails of the distributions of both positive weekly returns and negative returns. Tail risk measures such as value at risk and expected shortfall are computed using maximum likelihood methods. These measures can be used as indicators for the film distributors in the preparation of movie prints, or as references for actual or potential investors in the movie industry.
