Searchius is a collaborative search engine that produces search results based solely on user provided web-related data. We discuss the architecture of this system and how it compares to current state-of-the-art search engines. We show that the global users' preference over pages can be efficiently used as a metric of page quality, and that the inherent organization of the collected data can be used to discover related URLs. We also conduct an extensive experimental study, based on the web related data of 36483 users, to analyze the qualitative and quantitative characteristics of user collected URL collections, to investigate how well the users URL collections cover the web and discover the characteristics that affect the quality of the search results under the proposed setting.

Load Distribution Fairness in P2P Data Management Systems

Load Distribution Fairness in P2P Data Management Systems

International Conference on Data engineering

作者： Theoni Pitoura Peter Triantafillou Research Academic Computer Technology Institute and Computer Engineering and Informatics Department University of Patras Greece

ISBN: (纸本)1424408024

We address the issue of measuring storage, or query load distribution fairness in peer-to-peer data management systems. Existing metrics may look promising from the point of view of specific peers, while in reality being far from optimal from a global perspective. Thus, first we define the requirements and study the appropriateness of various statistical metrics for measuring load distribution fairness towards these requirements. The metric proposed as most appropriate is the Gini coefficient (G). Second, we develop novel distributed sampling algorithms to compute G on-line, with high precision, efficiently, and scalably. Third, we show how G can readily be utilized on-line by higher-level algorithms which can now know when to best intervene to correct load imbalances. Our analysis and experiments testify for the efficiency and accuracy of these algorithms, permitting the online use of a rich and reliable metric, conveying a global perspective of the distribution.

Multimodal fusion for Cued Speech language recognition

Multimodal fusion for Cued Speech language recognition

15th European Signal Processing Conference, EUSIPCO 2007

作者： Argyropoulos, Savvas Tzovaras, Dimitrios Strintzis, Michael G. Electrical and Computer Engineering Dept. Aristotle University of Thessaloniki Thessaloniki GR-54124 Greece Informatics and Telematics Institute Centre for Research and Technology Hellas Thermi-Thessaloniki GR-57001 Greece

In this paper, a novel method for Cued Speech language recognition is proposed. A multimodal processing framework is developed for the efficient fusion of the modalities under consideration. The robust feature extraction from the audio, lip shape and gesture modalities is also discussed. Moreover, the inherent correlation among the signals is modelled using a modified Coupled Hidden Markov Model. The contribution of each modality to the fused decision is modified by assessing its reliability and assigning a weighting factor to improve the accuracy of the recognized words. The method is experimentally evaluated and is shown to outperform methods that rely only on the perceivable information to infer the transmitted messages. © 2007 EURASIP.

Cost-balancing tolls for atomic network congestion games

3rd International Workshop on Internet and Network Economics, WINE 2007

We investigate the existence of optimal tolls for atomic symmetric network congestion games with unsplittable traffic and arbitrary non-negative and non-decreasing latency functions. We focus on pure Nash equilibria and a natural toll mechanism, which we call cost-balancing tolls. A set of cost-balancing tolls turns every path with positive traffic on its edges into a minimum cost path. Hence any given configuration is induced as a pure Nash equilibrium of the modified game with the corresponding cost-balancing tolls. We show how to compute in linear time a set of cost-balancing tolls for the optimal solution such that the total amount of tolls paid by any player in any pure Nash equilibrium of the modified game does not exceed the latency on the maximum latency path in the optimal solution. Our main result is that for congestion games on series-parallel networks with increasing latencies, the optimal solution is induced as the unique pure Nash equilibrium of the game with the corresponding cost-balancing tolls. To the best of our knowledge, only linear congestion games on parallel links were known to admit optimal tolls prior to this work. To demonstrate the difficulty of computing a better set of optimal tolls, we show that even for 2-player linear congestion games on series-parallel networks, it is NP-hard to decide whether the optimal solution is the unique pure Nash equilibrium or there is another equilibrium of total cost at least 6/5 times the optimal cost. © Springer-Verlag Berlin Heidelberg 2007.

Tsiatsos Computer Engineering and Informatics Department(CEID) University of Patras Greece Research Academic Computer Technology Institute Greece Department of Informatics Research Academic Computer Technology Institute (CTI) Aristotle University of Thessaloniki Greece

It is well known that both space and the spatial organization play an important role in our work and learning environments as well as in everyday life. There is a definite need for many persons to design their space along with an expert and to preview it in order to test its functionality. Many times there is a need for the inhabitants and workers to collaborate in order to co-design their space from distance. Multi-user 3D virtual environments are a powerful form of collaborative telecommunication applications, enabling the users to share a common three dimensional space and interact with each other as well as with the environment surrounding them, in order to collaboratively solve problems or aid learning processes. This paper presents the work done for extending a multi-user virtual environments platform, to support collaborative spatial design applications. Furthermore, a usage scenario is presented concerning the collaborative design of a classroom for educational purposes.

International Conference on Broadband Networks (BroadNets)

作者： Kyriakos G. Vlachos Computer Engineering and Informatics Department & Research Academic Computer Technology Institute University of Patras Rio Greece

In this paper, we study the burstification effect on the TCP synchronization and TCP congestion window mechanism. It is shown that short assembly times are optimal for flows with similar characteristics, while large assembly time provide a higher notion of fairness. In addition, this paper analyzes the synchronization of multiple TCP flows when aggregated together over the same optical bursts. It is shown that there is a strong TCP synchronization effect upon burst losses, in the sense that flows’ windows increase/decrease simultaneously, resulting to a significant variation of outgoing traffic. These deficiencies may be dealt with employing a multi-queue burst assembly scheme with different timers and taking into account the TCP dynamics.

IEEE International Symposium on World of Wireless Mobile and Multimedia Networks (WoWMoM)

作者： Antonios Alexiou Christos Bouras Evangelos Rekkas Research Academic Computer Technology Institute Greece and Computer Engineering and Informatics Department University of Patras Greece

This paper proposes a power control scheme for the efficient radio bearer selection in the Multimedia Broadcast/Multicast Service (MBMS) framework of Universal Mobile Telecommunications System (UMTS). The choice of the most efficient transport channel in terms ofpower consumption is a key point for the MBMS since a wrong transport channel selection for the transmission of the MBMS data could result to a significant decrease in the total capacity of the system. Diferent UMTS transport channels are examined and an algorithm that defines the switching point between dedicated and common radio bearers is proposed The proposed MBMSpower control scheme selects the transport channel that reduces the Node B's transmission power in every cell of the network with multicast users.

IEEE International Conference on Communications (ICC)

作者： K. Yiannopoulos E. Varvarigos K. Vlachos Computer Engineering and Informatics Department and Research Academic Computer Technology Institute University of Patras Rio Greece

In this paper, we present the architectural design of optical burst-buffers that can truly emulate input queuing and accommodate asynchronous burst operation. The architectural design uses wavelength converters and fixed feed-forward delay lines that are combined to form either a multiple-input buffer or a shared buffer. Both schemes are modular, allowing the logarithmic expansion of buffer size with the number of switching elements (wavelength converters).

The existence of good probabilistic models for the job arrival process and the delay components introduced at the different stages of job processing in a grid environment is important for the improved understanding of the computing concept envisioned by the Grid. In this study, we present a thorough analysis of the job arrival process in the EGEE infrastructure and the time durations a job spends at different states in the EGEE environment. We define four delay components of the total job delay and model each component separately. We observe that the job inter-arrival times at the grid level can be adequately modeled by a rounded exponential distribution, while the total job delay (from the time it is generated until the time it completes execution) is dominated by the computing element's queuing and worker node's execution times.

IEEE International Conference on e-Science and Grid Computing

作者： Panagiotis Kokkinos Emmanouel A. Varvarigos Nikolaos D. Doulamis Department of Computer Engineering and Informatics University of Patras and Research Academic Computer Technology Institute Patras Greece

Future grid networks should be able to provide quality of service (QoS) guarantees to their users. In this work we propose a framework for grid networks that provides deterministic delay guarantees to its guaranteed service (GS) users and best effort service to its best effort (BE) users. The proposed framework is theoretically and experimentally analyzed. We also define four types of computational resources based on the type of users (GS, BE) these resources serve and the priority they give them. We implement the proposed QoS framework for grids and verify that it not only satisfies the delay guarantees given to GS users, but also improves performance in terms of deadlines missed and resource use. In our simulations, data from a real grid network are used, validating in this way the appropriateness and usefulness of the proposed framework.
