3D Tracking by Catadioptric Vision Based on Particle Filters
Authors: Matteo Taiana, José Gaspar, Jacinto Nascimento, Alexandre Bernardino, Pedro Lima
Venue: RoboCup 2007: Robot Soccer World Cup XI (2008)

This paper presents a robust tracking system for autonomous robots equipped with omnidirectional cameras. The proposed method uses a 3D shape and color-based object model. This allows to tackle difficulties that arise when the tracked object is placed above the ground plane floor. Tracking under these conditions has two major difficulties: first, observation with omnidirectional sensors largely deforms the target's shape; second, the object of interest embedded in a dynamic scenario may suffer from occlusion, overlap and ambiguities. To surmount these difficulties, we use a 3D particle filter to represent the target's state space: position and velocity with respect to the robot. To compute the likelihood of each particle the following features are taken into account: i) image color; ii) mismatch between target's color and background color. We test the accuracy of the algorithm in a RoboCup Middle Size League scenario, both with static and moving targets.
Increasing Heat and/or Mass Transfer Rates in Impinging Jets
Authors: V. Tesař, Z. Trávníček
Venue: Journal of Visualization (2005)

First part of a survey drawing together findings of authors' research over a period of two decades on enhancing performance of impinging jets. The limiting factor is stagnant near-wall layer across which the transfer takes place by conduction. Results of research aimed at removing this limitation have been partly published but mostly in literature inaccessible to international readers. Flow visualizations played an important role in identifying the problem areas, leading to a number of novel implementation concepts to be described in the second part.
Computational self-assembly
Authors: Pierre-Louis Curien, Vincent Danos, Jean Krivine, Min Zhang
Venue: Theoretical Computer Science (2008)

The object of this paper is to probe the computational limits of an applied concurrent language called @k. This language describes how agents can bind and modify each other. It is meant as a syntactic medium to build, discuss and execute descriptions of cellular signalling pathways. However, it can be studied independently of its intended interpretation, and this is what we are doing here. Specifically, we define a reduction of @k to a fragment where interactions can involve at most two agents at a time. The translation relies on an implicit causality analysis which permits escaping deadlocks. It incurs only a linear blow up in the number of rules. Its correctness is spelt out in terms of the existence of a specific weak bisimulation and is proved in detail. To compensate for the binary restriction, one allows components to create unique names. When using acyclic rules, this additional facility of name creation is not needed and @k can be reduced to a binary form as is.
Multimedia Interfaces for BSL Using Lip Readers
Authors: Faramaz Eyasim Joumun, Paul Gnanayutham, Jennifer George
Venue: Proceedings of the 11th international conference on Computers Helping People with Special Needs (2008)

This paper deals with mainly the profoundly deaf people who are beginning to learn the British Sign Language (BSL) as their first language for communication. These beginners could be children, teenagers or even adults who have hearing problems. There are already quite a few BSL learning websites and Lip Reading software available on the market. However, there is no such software that associates the two associated problems although there might be BSL users who can benefit from Lip Reading. This could help them not only for communication but also enable them to interact more with people with a normal hearing range, who as a matter of fact, form a major part of the society we live in. The artifact aims to be run on most computers making it easier for people to access and use it without the need for any additional costly features.
Bialgebra views: a way for polytypic programming to cohabit with data abstraction
Authors: Pablo Nogueira, Juan José Moreno-Navarro
Venue: Proceedings of the ACM SIGPLAN workshop on Generic programming (2008)

Polytypic programming and data abstraction are important concepts in designing functional programs, but they do not fit well together. Polytypic programming currently depends on making public a free data type representation, while data abstraction depends on hiding the representation. This paper proposes the bialgebra views mechanism as a means of reconciling this conflict. Bialgebra views enable the specification of type structure according to interfaces, not representations, thus combining the genericity of polytypic programming with the information hiding of data abstraction, and narrowing the gap between generic programming in the functional and object-oriented paradigms.
The TSUBAME Cluster Experience a Year Later, and onto Petascale TSUBAME 2.0
Authors: Satoshi Matsuoka
Venue: Proceedings of the 14th European PVM/MPI User's Group Meeting on Recent Advances in Parallel Virtual Machine and Message Passing Interface (2007)

TSUBAME (Tokyo-tech Supercomputer and Ubiquitously Accessible Massstorage Environment) is a new supercomputer installed at Tokyo Institute of Technology in Tokyo, Japan, on April 1st, 2006, and as of 2007 facilitating over 85 Teraflops of peak compute power with acceleration, 22 Terabytes of memory, and 1.6 Petabytes of online disk storage, "Fat Node" as well as fast parallel interconnect-architectural principles based on traditional supercomputers. TSUBAME became the fastest and largest supercomputer in Asia in terms of performance, memory and storage capacity etc., starting from the 38.18 Teraflops performance (7th overall) for the June 2006 Top500 announcement, and taking the fastest in Asia crown for 3 consecutive Top500s in a row (currently at 48.88 Teraflops). At the same time, being PC architecture-based, TSUBAME, being a large collection of PC servers, allows for offering much broader services than traditional supercomputers resulting in a much wider user base, including incubation of novice students. We term such architectural and operational property of TSUBAME as "Everybody's Supercomputer", as opposed to traditional supercomputers with very limited number of users, thus making their financial justifications increasingly difficult.

Parallelization and Distribution Strategies of Large Bioinformatics Requests over the Grid
Authors: Eddy Caron, Frédéric Desprez, Gaël Mahec
Venue: Proceedings of the 8th international conference on Algorithms and Architectures for Parallel Processing (2008)

This paper focuses on simultaneous scheduling of computation and data replication for life science applications on the grid. We present an adaptive algorithm based on the SRA algorithm (Static Joint Replication and Scheduling) [4] with more dynamicity for the jobs frequencies. The use of a linear program giving a databases mapping on the nodes and a jobs distribution schema, ensures us that our data placement and jobs distribution will be near the optimal solution, as long as the informations about the jobs frequencies are right. We validate our results with large jobs submissions simulations on a realistic platform.
Relative Linkage Disequilibrium: A New Measure for Association Rules
Authors: Ron Kenett, Silvia Salini
Venue: Proceedings of the 8th industrial conference on Advances in Data Mining: Medical Applications, E-Commerce, Marketing, and Theoretical Aspects (2008)

Association rules are one of the most popular unsupervised data mining methods. Once obtained, the list of association rules extractable from a given dataset is compared in order to evaluate their importance level. The measures commonly used to assess the strength of an association rule are the indexes of support, confidence, and the lift.Relative Linkage Disequilibrium (RLD) was originally proposed as an approach to analyse both quantitatively and graphically general two way contingency tables. RLD can be considered an adaptation of the lift measure with the advantage that it presents more effectively the deviation of the support of the whole rule from the support expected under independence given the supports of the LHS (A) and the RHS (B). RLD can be interpreted graphically using a simplex representation leading to powerful graphical display of association relationships. Moreover the statistical properties of RLD are known so that confirmatory statistical tests of significance or basic confidence intervals can be applied.This paper will present the properties of RLD in the context of association rules and provide several application examples to demonstrate it's practical advantages.
BREIN, Towards an Intelligent Grid for Business
Authors: Eduardo Oliveros, Henar Muñoz, David Cantelar, Steve Taylor
Venue: Proceedings of the 5th international workshop on Grid Economics and Business Models (2008)

Nowadays companies' communication is mainly static and does not allow for the flexibility and adaptability required to meet changing requirements or to support unexpected situations. The BREIN project's main objective is to create an infrastructure that allows companies to collaborate in a dynamic business environment. Moreover, BREIN is strongly focused on SMEs which do not have enough knowledge or resources to participate in this kind of environments. To address this knowledge gap, the BREIN framework reduces relations' complexity and aims to provide a solution where essential requirements to build this collaborative environment such as self-management capabilities, security, trust and reliability are all integrated into one business network.
Robust Fuzzy Output Sliding Control without the Requirement of State Measurement
Authors: Y. J. Huang, S. H. Chang, T. C. Kuo
Venue: Journal of Intelligent and Robotic Systems (2008)

A robust fuzzy output sliding control for nonlinear robotic arms is proposed in this paper. The proposed method not only retains the advantages of the conventional sliding mode control such as robustness against parameter variations and external disturbances, but also uses measurable output signals to define the sliding surface function. A fuzzy controller is developed to modify the control law to avoid state measurement. Control system stability is proved by using the Lyapunov stability theorem. The system robustness is guaranteed. Simulations results demonstrate the validity and effectiveness of the proposed method for uncertain nonlinear robotic arms.
Can a nominal financial result and a nominal value of return on equity constitute a base for an assessment of effectiveness? Testing a research hypothesis
Authors: Justyna Franc-Dabrowska
Venue: International Journal of Electronic Finance (2008)

The conducted researches indicate explicitly that the assessment of the enterprise on the basis of the nominal value of the financial result and the nominal return on equity can lead to false financial decisions. In economies characterised by high inflation rates, financial results and the return on equity should not be treated as indisputable criteria of the financial situation of companies. An increase in profit driven by inflation should be considered as well; in some extreme situations, the division of such inflationary profit may lead to bankruptcy. This research is the first of this kind of analysis of agricultural companies in Poland.
Autonomic Management Policy Specification: From UML to DSML
Authors: Benoît Combemale, Laurent Broto, Xavier Crégut, Michel Daydé, Daniel Hagimont
Venue: Proceedings of the 11th international conference on Model Driven Engineering Languages and Systems (2008)

Autonomic computing is recognized as one of the most promizing solutions to address the increasingly complex task of distributed environments' administration. In this context, many projects relied on software components and architectures to provide autonomic management frameworks. We designed such a component-based autonomic management framework, but observed that the interfaces of a component model are too low-level and difficult to use. Therefore, we introduced UML diagrams for the modeling of deployment and management policies. However, we had to adapt/twist the UML semantics in order to meet our requirements, which led us to define DSMLs. In this paper, we present our experience in designing the Tune system and its support for management policy specification, relying on UML diagrams and on DSMLs. We analyse these two approaches, pinpointing the benefits of DSMLs over UML.
A Genetic Programming Environment for System Modeling
Authors: Efstratios F. Georgopoulos, George P. Zarogiannis, Adam V. Adamopoulos, Anastasios P. Vassilopoulos, Spiridon D. Likothanassis
Venue: Proceedings of the 5th Hellenic conference on Artificial Intelligence: Theories, Models and Applications (2008)

In the current paper we present an integrated genetic programming environment with a graphical user interface (GUI), called jGPModeling. The jGPModeling environment was developed using the JAVA programming language, and is an implementation of the steady-state genetic programming algorithm. That algorithm evolves tree based structures that represent models of input --- output relation of a system. During the design and implementation of the application, we focused on the execution time optimization and tried to limit the bloat effect. In order to evaluate the performance of the jGPModeling environment, two different real world system modeling tasks were used.

Authors: Eleni Kaldoudi, Panagiotis Bamidis, Miltiadis Papaioakeim, Vassilis Vargemezis
Venue: Proceedings of the 2008 21st IEEE International Symposium on Computer-Based Medical Systems (2008)

During the last few decades, medical education is shifting is increasingly embracing active learning approaches. This shift from teaching to learning is also strongly related to an involvement of information and communication technology, and especially the Internet and the Web. The emergence of Internet 2.0 is indeed being stressed as a promising tool for advanced support of medicine and medical education. Although Web 2.0 emphasizes on participation, in its early days is still used in the majority of cases to hold and provide content (albeit created dynamically and via peer participation and collaboration) and then systematically deliver it to students. In this paper, we propose the use of wikis and blogs not just for creation and promotion of information, but as active tools to support problem based learning in medicine. In this approach, students and instructors use the web as a virtual place to collaborate and create new knowledge and new educational experiences.
DCCP: Transport Protocol with Congestion Control and Unreliability
Authors: Yuan-Cheng Lai
Venue: IEEE Internet Computing (2008)

The Datagram Congestion Control Protocol (DCCP) is a new transport protocol standard that the IETF recently proposed. Because DCCP simultaneously features congestion control and unreliable transmission, it's especially suited to multimedia streaming applications and has thus received much attention. This article introduces DCCP's main characteristics and operation.
Weight-scale, XRR and corona charge method on back-end dielectrics for 65 and 45nm technology nodes
Authors: D. Fossati, R. Duru, S. Desmercières, J. -C. Royer
Venue: Microelectronic Engineering (2008)

The monitoring of the back-end dielectrics for 65 and 45nm technology nodes is of great interest to ensure the integration of those materials into damascene structure. Several metrology methods were compared for density and k value measurements. It was shown that the densities measured with XRR and weight-scale were identical and that density could be correlated to corona charge method k value thanks to a Clausius-Mosotti-like relation. According to these results, it appeared that, for uniformly deposited and stable materials, weight-scale measurements can give accurate and fast monitorings. On the contrary, non-homogeneous materials should preferably be monitored with XRR or corona charge method depending on the controlled parameter.

Characterizing Bots' Remote Control Behavior
Authors: Elizabeth Stinson, John C. Mitchell
Venue: Proceedings of the 4th international conference on Detection of Intrusions and Malware, and Vulnerability Assessment (2007)

A botnet is a collection of bots, each generally running on a compromised system and responding to commands over a "command-and-control" overlay network. We investigate observable differences in the behavior of bots and benign programs, focusing on the way that bots respond to data received over the network. Our experimental platform monitors execution of an arbitrary Win32 binary, considering data received over the network to be tainted, applying library-call-level taint propagation, and checking for tainted arguments to selected system calls. As a way of further distinguishing locally-initiated from remotely-initiated actions, we capture and propagate "cleanliness" of local user input (as received via the keyboard or mouse). Testing indicates behavioral separation of major bot families (agobot, DSNXbot, evilbot, G-SySbot, sdbot, Spybot) from benign programs with low error rate.
The Technical Research and System Realization of 3D Garment Fitting System Based on Improved Collision-Check Algorithm
Authors: Qingqing Chen, Junfeng Yao, Hanhui Zhang, Kunhui Lin
Venue: Proceedings of the 3rd international conference on Technologies for E-Learning and Digital Entertainment (2008)

Nowadays, the study of 3d garment fitting technology is going mature. There has a series of research results in clothes-stitching, collision-checking and so on. But the trad collision-checking algorithm could result in endless loop, and it is more complex. There is no internal system which is perfect and has been spread. This system improved the trad constructing process of bounding-box, avoiding the endless loop that appeared in trad bounding-box constructing process. The system used easier algorithm to check collisions, reduce the complexity and can do precise and fast collision-check between clothes and human body. The 3D garment fitting system introduced in this paper can simulate the virtual fitting of 3D garments and set out the effect of it. This system uses Client/ Server mode. Users download Client and garment patches and run them at local computers. In this way, the system can solve the slow-updating problem of 3D images in 3D internet fitting system generated by slow net rate. It uses imported the 3DS 's mannequin to setup human body models, and solves the singular problem of motion and pose and the lacking problem of face and extremities generated by human platform modeling. Users design 2D garment patches, then the system would realize the transforming from 2D garment patches to 3D garments automatically. So the system can update garment style rapidly. It also has dynamic simulation function and realizes the reality of different fabric. We trust that this system could excite the potential of sell effectively after it is perfected and is extensively used.

A Spam Filtering Method Learning from Web Browsing Behavior
Authors: Taiki Takashita, Tsuyoshi Itokawa, Teruaki Kitasuka, Masayoshi Aritsugi
Venue: Proceedings of the 12th international conference on Knowledge-Based Intelligent Information and Engineering Systems, Part II (2008)

In this paper a spam filtering method is proposed. We focus on user behavior that most email users browse the Web. The method reduces troublesome maintenance of the spam filter, since the filter learns from Web browsing behavior in the background. The method uses Web browsing behavior of each user to learn ham words. Ham words are picked up from browsed Web pages using TF-IDF and stored in the database called ham words list. For each received email, the method extracts keywords from the email, including Web pages of the URLs. If some keywords are in the ham words list, the email is treated as a ham. In our experiments, several spam emails which cannot be detected by a Bayesian filter are detected as spams.

Performance evaluation of video streaming over ad hoc networks using flat and hierarchical routing protocols
Authors: Pau Arce, Juan C. Guerri, Ana Pajares, Oscar Láro
Venue: Mobile Networks and Applications (2008)

A performance evaluation of real time services (such as video streaming) over mobile ad-hoc networks using both hierarchical and flat routing protocols is shown in this paper. A variety of workload and scenarios, as characterized by mobility, load and size of the ad hoc network have been simulated using NS-2. We use OLSR (Optimized Link State Protocol) as the flat routing protocol and our own implementation of HOLSR (Hierarchical OLSR)--which uses HNA (Host and Network Association) messages-as the hierarchical one, modifying other previous HOLSR version and maintaining the maximum compatibility with the flat OLSR. We carry out a complete comparison between these protocols focused on video evaluation. The simulation lets us compare the quality of service (QoS) of the video streaming paying attention to objective parameters (PSNR, packet delivery ratio, packet delay and interruptions). Some drawbacks of the hierarchical environment are also analyzed, as the link load between cluster heads and the lack of QoS-state-aware in HOLSR design. Quantitative results indicate that the protocol overhead is reduced (more than 40% in larger networks) and the video quality is improved (from 1 to 6 dB in certain cases) using hierarchical protocols.
