Validation and Experimentation of a Tourism Recommender Agent based on a Graded BDI Model
Authors: Ana Casali, Lluís Godo, Carles Sierra
Venue: Proceeding of the 2008 conference on Artificial Intelligence Research and Development: Proceedings of the 11th International Conference of the Catalan Association for Artificial Intelligence (2008)

In this paper, a validation and an experimentation of the use of graded BDI agents is reported. This agent model has been proposed to specify agents capable to deal with the environment uncertainty and with graded attitudes in an efficient way. As a case study we focus on a Tourism Recommender Agent specified using this agent model. The experimentation on the case study aims at proving that this agent model is useful to develop concrete agents showing different and rich behaviours. We also show that the results obtained by these particular recommender agents using graded attitudes improve those achieved by agents using non-graded attitudes.
Field-lens Display: Headtracking enables 3D image viewing at any position
Authors: Kunio Sakamoto, Tsukasa Nishida
Venue: Proceeding of the 2006 conference on Advances in Intelligent IT: Active Media Technology 2006 (2006)

Many 3D visualization technologies have been invented, but none ever had a broad success. This paper describes the field lens display for viewing stereoscopic images. On the conventional systems, several viewers can perceive a stereo pair simultaneously and they can move independently without special equipment. However these systems have the defect that it needs the complicated optical system for combining a stereo pair image. To overcome this optical problem, we developed the dual LCD panel using two liquid crystal layers. This display panel enables observers to view full screen high resolution images. In this paper, we describe the method of 3D measuring using a single camera for tracking users' positions and a 3D display system using a field-lens which can display full screen high resolution views. This 3D display can solve the traditional defect that the horizontal resolution of each image is divided in half.
Proceedings of The Third Workshop on Analytics for Noisy Unstructured Text Data
Venue: ACM International Conference Proceeding Series (2009)

Noise in text comes from two types of sources, broadly speaking : (i) text produced by processing signals intended for human use such as printed/handwritten documents, spontaneous speech, and camera-captured scene images and (ii) human generated natural language text such as electronic text from the Internet (emails, message boards, newsgroups, blogs, wikis, chat logs and web pages), contact centers (customer complaints, emails, call transcriptions, message summaries), and mobile phones (text messages). The pervasiveness of such noisy data is evident and the importance of analyzing such data is obvious and analyzing this requires moving beyond traditional text analytics techniques. The Third Workshop on Analytics for Noisy Unstructured Text Data (AND 2009) follows two successful previous editions: AND 2007 (in conjunction with the 20th Joint Conference on Artificial Intelligence [IJCAI]) and AND 2008 (in conjunction with the 31st Annual International ACM SIGIR Conference). AND 2007 was successful in creating awareness and emphasizing importance of noisy text analytics. It brought together industrial and academic researchers from various areas leading to high quality papers that were featured in a special issue of the International Journal on Document Analysis and Recognition (IJDAR). Researchers also shared several synthetic and real datasets from various domains for benefit of the community. AND 2008 built on the success of the first edition and brought together a larger community of people from different parts of the world with a specific focus on Information Retrieval as the application area. Another special issue of IJDAR is currently under production. Following this trend, the third edition of the AND workshop is being organized in conjunction with the Tenth International Conference on Document Analysis and Recognition (ICDAR'2009). Once again, we expect to see a range of thought-provoking discussions on methods for handling noise in text and related topics. The workshop Call for Papers had a good response, like previous editions. We received 22 submissions spanning a diverse set of issues relevant to noisy text analytics. Each submission was reviewed by at least three members of the program committee. In the workshop, there will be 15 contributed presentations, invited talks by Dr. Hildelies Balk (Programme Manager for the EU project IMPACT) and Dr. Venu Govindaraju (Distinguished Professor of CSE at SUNY, Buffalo), and several working group discussion sessions spread throughout the day. Through these opportunities for interaction, we hope AND 2009 will continue to foster the international research community as was the case with the first two AND workshops.
Possibilistic Influence Diagrams
Authors: Laurent Garcia, Régis Sabbadin
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)

In this article we present the framework of Possibilistic Influence Diagrams (PID), which allow to model in a compact form problems of sequential decision making under uncertainty, when only ordinal data on transitions likelihood or preferences are available. The graphical part of a PID is exactly the same as that of usual influence diagrams, however the semantics differ. Transition likelihoods are expressed as possibility distributions and rewards are here considered as satisfaction degrees. Expected utility is then replaced by anyone of two possibilistic qualitative utility criteria for evaluating strategies in a PID. We describe a decision tree-based method for evaluating PID and computing optimal strategies. We then study the computational complexity of PID-related problems (computation of the value of a policy, computation of an optimal policy).

Modal analysis of different types of classical guitar bodies
Authors: Ioan Curtu, Mariana D. Stanciu, Nicolae C. Cretu, Calin I. Rosca
Venue: Proceedings of the 10th WSEAS international conference on Acoustics & music: theory & applications (2009)

Resonant frequencies and Chladni patterns of different types of classical guitar bodies were investigated to continue and further develop the understanding of the tonal qualities of guitars. The acoustic boxes with four types of strutting systems were analyzed. For this, a B&K mini-shaker, to excite the structures, and three B&K 4517-002 accelerometers located on top, at the back and on the sides of the sound box were used. The input and output signals were collected with a Data Acquisition device (DAQ) and processed to discover resonant frequencies and harmonics. During the experiments, Chladni patterns were obtained using powder sand on the surface. The method used does provide some insight regarding the vibrations of classical guitar bodies such as the influence of the strutting system on the modal shapes and dynamic response. The paper carries on the theoretical studies presented in works [4], [5], [6], [14], [15], [16], with experimental research.
A Multivalued logic model of planning
Authors: M. Baioletti, A. Milani, V. Poggioni, S. Suriani
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)

In this work a model for planning with multivalued fluents and graded actions, based on the infinite valued Lukasiewicz logic, is introduced. In multivalued planning, fluents can assume truth values in the interval [0, 1] and actions can be executed at different application degrees also varying in [0, 1]. The notions of planning problem and solution plan also reflect a multivalued approach. Multivalued fluents and graded actions allow to model many real situations where some features of the world cannot be modeled with boolean values and where actions can be executed with varying strength which produces graded effects as well. Even if most existing planning models fail to address this kind of domains, our model is comparable with models allowing flexible actions and soft constraints. A correct/complete algorithm which solves bounded multivalued planning problems based on MIP compilation is also described and a prototype implementation is presented.
Tools for Procedural Generation of Plants in Virtual Scenes
Authors: Armando Re, Francisco Abad, Emilio Camahort, M. C. Juan
Venue: Proceedings of the 9th International Conference on Computational Science (2009)

Creating interactive graphics applications that present to the user realistic natural scenes is very difficult. Natural phenomena are very complex and detailed to model, and using traditional modeling techniques takes huge amounts of time and requires skilled artists to obtain good results.Procedural techniques allow to generate complex objects by defining a set of rules and selecting certain parameters. This allows to speed up the process of content creation and also allows to create objects on-the-fly, when needed. On-demand generation of scenes enables the authors to create potentially infinite worlds.This survey identifies the main features of the most used systems that implement procedural techniques to model plants and natural phenomena and discuss usability issues.
Design and implementation of MobiSEC: A complete security architecture for wireless mesh networks
Authors: Fabio Martignon, Stefano Paris, Antonio Capone
Venue: Computer Networks: The International Journal of Computer and Telecommunications Networking (2009)

Wireless mesh networks (WMNs) have emerged recently as a technology for next-generation wireless networking. They consist of mesh routers and clients, where mesh routers are almost static and form the backbone of WMNs. WMNs provide network access for both mesh and conventional clients. In this paper we propose MobiSEC, a complete security architecture that provides both access control for mesh users and routers as well as a key distribution scheme that supports layer-2 encryption to ensure security and data confidentiality of all communications that occur in the WMN. MobiSEC extends the IEEE 802.11i standard exploiting the routing capabilities of mesh routers; after connecting to the access network as generic wireless clients, new mesh routers authenticate to a central server and obtain a temporary key that is used both to prove their credentials to neighbor nodes and to encrypt all the traffic transmitted on the wireless backbone links. A key feature in the design of MobiSEC is its independence from the underlying wireless technology used by network nodes to form the backbone. Furthermore, MobiSEC allows seamless mobility of both mesh clients and routers. MobiSEC has been implemented and integrated in MobiMESH, a WMN implementation that provides a complete framework for testing and analyzing the behavior of a mesh network in real-life environments. Moreover, extensive simulations have been performed in large-scale network scenarios using Network Simulator. Numerical results show that our proposed architecture considerably increases the WMN security, with a negligible impact on the network performance, thus representing an effective solution for wireless mesh networking.

Authors: Wenchuan Yang, Qiong Wu, Ping Hou, Fei Cui
Venue: Proceeding of the 2006 conference on Advances in Intelligent IT: Active Media Technology 2006 (2006)

The NGN will be a syncretic network mainly focuses on processing everything over IP. The innumerous future user and various businesses require the NGN to provide high quality of business. The study of Complex Network indicates that real network have scale-free property and small-world property. In this paper we will study NGN based on the theory and methods of Complex Network. We will discover the Power-law phenomena in the present Telecommunication network and Internet congestion, which show robust to unexpected attack but very fragile to intentional attack. We will design an adaptive NGN congestion-monitoring prototype model based on Power-law to ensure the secure serves and QoS of NGN.
Interactive Control over a Programmable Computer Network Using a Multi-touch Surface
Authors: Rudolf Strijkers, Laurence Muller, Mihai Cristea, Robert Belleman, Cees Laat, Peter Sloot, Robert Meijer
Venue: Proceedings of the 9th International Conference on Computational Science (2009)

This article introduces the Interactive Network concept and describes the design and implementation of the first prototype. In an Interactive Network humans become an integral part of the control system to manage programmable networks and grid networks. The implementation consists of a multi-touch table that allows multiple persons to manage and monitor a programmable network simultaneously. The amount of interactive control of the multi-touch interface is illustrated by the ability to create and manipulate paths, which are either end-to-end, multicast or paths that contain loops. First experiences with the multi-touch table show its potential for collaborative management of large-scale infrastructures.
Effects of Resource Distribution and Feedback on Computer-Mediated Collaboration in Dyads
Authors: Joerg Zumbach, Peter Reimann, Jochen Schönemann
Venue: Proceeding of the 2005 conference on Towards Sustainable and Scalable Educational Innovations Informed by the Learning Sciences: Sharing Good Practices of Research, Experimentation and Innovation (2005)

Two methods for fostering collaborative behavior in dyads are compared: a feedback-mechanism to scaffold collaborative behavior, and the use of distributed learning resources. Based on recent research on what constitutes effective collaboration behavior, we developed a coding scheme to categorize learner-learner interaction as collaboration. In a collaboration environment for learner dyads specifically implemented to test our hypotheses, a human observer identified, in parallel with students' interactions, instances of real collaboration, and gave online feedback. In the same two-factorial design, we varied the resources available to the partners. The influence of these interventions on outcomes related to knowledge acquisition, problem-solving, group climate and collaborative behavior was tested. Overall, collaboration was infrequent. Results suggest there are benefits in providing a feedback approach in fostering collaboration and enhancing problem-solving quality.
A spatially distributed model for foreground segmentation
Authors: Patrick Dickinson, Andrew Hunter, Kofi Appiah
Venue: Image and Vision Computing (2009)

Foreground segmentation is a fundamental first processing stage for vision systems which monitor real-world activity. In this paper, we consider the problem of achieving robust segmentation in scenes where the appearance of the background varies unpredictably over time. Variations may be caused by processes such as moving water, or foliage moved by wind, and typically degrade the performance of standard per-pixel background models. Our proposed approach addresses this problem by modeling homogeneous regions of scene pixels as an adaptive mixture of Gaussians in color and space. Model components are used to represent both the scene background and moving foreground objects. Newly observed pixel values are probabilistically classified, such that the spatial variance of the model components supports correct classification even when the background appearance is significantly distorted. We evaluate our method over several challenging video sequences, and compare our results with both per-pixel and Markov Random Field based models. Our results show the effectiveness of our approach in reducing incorrect classifications.
Investigating business-IT alignment through multi-disciplinary goal concepts
Authors: Sase Narine Singh, Carson Woo
Venue: Requirements Engineering (2009)

The alignment of information technology (IT) with business strategies is optimal when harmony exists between organizational and system goals. Empirical evidence reveals that effective strategic alignment leads to superior financial performance for organizations. This observation has spurred extensive research into business-IT alignment. Yet, the issue of alignment remains a top concern for CIOs. We argue that the parochial view undertaken by past research into business-IT alignment is a probable cause for continuing system failures. Furthermore, strategic alignment research is limited and devoid within the requirements engineering discipline. In this paper, we highlight existing shortfalls of research in business-IT alignment, and bring to light insights that may be offered by other disciplines to augment this field. Subscribing to a multi-disciplinary perspective, we develop a goal-based framework that incorporates goals from various literatures in investigating business-IT alignment. One of the novelties of our proposed framework lies in its delineation between goals that have been originally assigned to stakeholders versus those interpreted by stakeholders. Additionally, the framework includes constructs at the strategic level for supporting the rationale of strategic level goals. We tested the usefulness and usability of this methodology in an organization with a newly developed information system founded on strategic business goals and reported lessons learnt from both researchers&#x2019; and practitioners&#x2019; perspectives.
