A strategy for identification and information of resources in a grid
Authors: Lourival A. de Góis, Marcos M. Tenório, Walter da Cunha Borelli
Venue: Proceedings of the 2008 Euro American Conference on Telematics and Information Systems (2008)

This article proposes the use of idle resources identification and information strategy in a decentralized management system. The used approach gives priority to the low computational cost inherent to this process through the generation of load rates and idleness across many types of movable averages. They show in a different way the actual situation of shared resources, as well as the communication of them to the domain manager without overloading the net infrastructure. The results represent how these goals were reached by the use of an appropriate average together with the previously established rules between evolved parts.
A framework for ontology-based service selection in dynamic environments
Authors: Murat Sensoy
Venue: Proceedings of the 22nd national conference on Artificial intelligence - Volume 2 (2007)

Previous approaches to service selection are mainly based on capturing and exchanging the ratings of consumers to providers. However, ratings reflect tastes of the raters. Therefore, service selection using ratings may mislead the consumers having a taste different than that of the raters. We propose to use experiences instead of the ratings. Experiences are the representation of what is requested by a consumer and what is received at the end. Unlike ratings, experiences do not reflect the opinion of the others, but the actual story between consumers and providers concerning a service demand. Using experiences, the consumer models the services of a provider for a specific service demand and selects the provider that is expected to satisfy the consumer the most. Our simulations show that proposed approach significantly increases the overall satisfaction of the service consumers.
Theoretical evaluation of estimation methods for data-oriented parsing
Authors: Willem Zuidema
Venue: Proceedings of the Eleventh Conference of the European Chapter of the Association for Computational Linguistics: Posters & Demonstrations (2006)

We analyze estimation methods for Data-Oriented Parsing, as well as the theoretical criteria used to evaluate them. We show that all current estimation methods are inconsistent in the "weight-distribution test", and argue that these results force us to rethink both the methods proposed and the criteria used.

Venue: Proceedings of the 8th international conference on International conference for the learning sciences - Volume 3 (2008)

This symposium brings together a panel of researchers using contrasting case methodology to analyze computer-supported collaborative learning in a wide range of learning environments. Such analyses can help researchers better understand the differences in the collaborative processes by sharpening researchers' perception and facilitating the discovery of appropriate explanations for these differences.
A language and framework for invariant-driven transformations
Authors: Yanhong A. Liu, Michael Gorbovitski, Scott D. Stoller
Venue: Proceedings of the eighth international conference on Generative programming and component engineering (2009)

This paper describes a language and framework that allow coordinated transformations driven by invariants to be specified declaratively, as invariant rules, and applied automatically. The framework supports incremental maintenance of invariants for program design and optimization, as well as general transformations for instrumentation, refactoring, and other purposes. This paper also describes our implementations for transforming Python and C programs and experiments with successful applications of the systems in generating efficient implementations from clear and modular specifications, in instrumenting programs for runtime verification, profiling, and debugging, and in code refactoring.
Concurrent updating transactions on versioned data
Authors: Tuukka Haapasalo, Seppo Sippu, Ibrahim Jaluta, Eljas Soisalon-Soininen
Venue: Proceedings of the 2009 International Database Engineering & Applications Symposium (2009)

Modern database applications increasingly often require access to historical versions of the database. Storing such multiversion data in a single-version B+ -tree database index is inefficient, especially for key-range queries. In this article, we present an index structure called the concurrent multiversion B+ -tree (CMVBT) for efficiently storing and querying multiversion data. The CMVBT structure uses an asymptotically optimal transactional multiversion B+ -tree (TMVBT) index as the main data storage. and a separate B+ -tree index called the versioned B+ -tree (VBT) to hold the updates of active transactions. The updates of committed transactions are moved, one transaction at a time, from the VBT into the TMVBT. This organization of two separate index structures allows us to maintain the asymptotic optimality guarantees of the TMVBT even in the presence of concurrent updating transactions. We provide concurrent algorithms for updating and reading the CMVBT structure. Our CMVBT algorithms can be used with the standard snapshot isolation concurrency-control and ARIES-based recovery algorithms to allow multiple read-only and updating transactions, to operate concurrently on the structure. Transaction rollback is also supported for all updating transactions, either entirely or up to a preset savepoint.
Capturing hair assemblies fiber by fiber
Authors: Wenzel Jakob, Jonathan T. Moon, Steve Marschner
Venue: ACM Transactions on Graphics (TOG) (2009)

Hair models for computer graphics consist of many curves representing individual hair fibers. In current practice these curves are generated by ad hoc random processes, and in close-up views their arrangement appears plainly different from real hair. To begin improving this situation, this paper presents a new method for measuring the detailed arrangement of fibers in a hair assembly. Many macrophotographs with shallow depth of field are taken of a sample of hair, sweeping the plane of focus through the hair's volume. The shallow depth of field helps isolate the fibers and reduces occlusion. Several sweeps are performed with the hair at different orientations, resulting in multiple observations of most of the clearly visible fibers. The images are filtered to detect the fibers, and the resulting feature data from all images is used jointly in a hair growing process to construct smooth curves along the observed fibers. Finally, additional hairs are generated to fill in the unseen volume inside the hair. The method is demonstrated on both straight and wavy hair, with results suitable for realistic close-up renderings. These models provide the first views we know of into the 3D arrangement of hair fibers in real hair assemblies.
Intelligent Data Analysis in the 21st Century
Authors: Paul Cohen, Niall Adams
Venue: Proceedings of the 8th International Symposium on Intelligent Data Analysis: Advances in Intelligent Data Analysis VIII (2009)

When IDA began, data sets were small and clean, data provenance and management were not significant issues, workflows and grid computing and cloud computing didn't exist, and the world was not populated with billions of cellphone and computer users. The original conception of intelligent data analysis -- automating some of the reasoning of skilled data analysts -- has not been updated to account for the dramatic changes in what skilled data analysis means, today. IDA might update its mission to address pressing problems in areas such as climate change, habitat loss, education, and medicine. It might anticipate data analysis opportunities five to ten years out, such as customizing educational trajectories to individual students, and personalizing medical protocols. Such developments will elevate the conference and our community by shifting our focus from arbitrary measures of the performance of isolated algorithms to the practical, societal value of intelligent data analysis systems.
PCSP: A Probable Concurrent Secure and Portable Peer-to-Peer Protocol
Authors: Graciela Perera, Robert Gilliland
Venue: Proceedings of the 2009 Ninth Annual International Symposium on Applications and the Internet (2009)

Unstructured Peer-to-Peer (P2P) networks for content distribution are decentralized and robust.Searching for content in the network is based on the Gnutella protocol which does not provide security.Communication between two or more peers is secure if it can provide authentication and ensures the confidentially and integrity of the data exchanged.Authentication enables the identity verification of the devices sending and receiving the data. Confidentiality and integrity of the data guarantee that only the users that are authorized can understand the data and that an adversary is unable to modify the data exchanged.The challenge is how to authenticate users and establish a decentralized protocol that exploits concurrency and can provide confidentiality and integrity in content distribution networks? We propose the design of a Probable Concurrent Secure and Portable (PCSP) Local Look-up search P2P protocol. PCSP is based on the Diffie-Hellman key agreement protocol (DH) to establish a shared session key that can provide confidentiality and integrity. Authentication is achieved by concurrent processed secretly encrypting the Internet Address (IP) of the peer exchanging the key in a bloom filter, and hiding the existence of the bloom filter in a picture.
Improved morpho-phonological sequence processing with constraint satisfaction inference
Authors: Antal van den Bosch, Sander Canisius
Venue: Proceedings of the Eighth Meeting of the ACL Special Interest Group on Computational Phonology and Morphology (2006)

In performing morpho-phonological sequence processing tasks, such as letter-phoneme conversion or morphological analysis, it is typically not enough to base the output sequence on local decisions that map local-context input windows to single output tokens. We present a global sequence-processing method that repairs inconsistent local decisions. The approach is based on local predictions of overlapping trigrams of output tokens, which open up a space of possible sequences; a data-driven constraint satisfaction inference step then searches for the optimal output sequence. We demonstrate significant improvements in terms of word accuracy on English and Dutch letter-phoneme conversion and morphological segmentation, and we provide qualitative analyses of error types prevented by the constraint satisfaction inference method.

Authors: Sébastien Kubicki, Sophie Lepreux, Yoann Lebrun, Philippe Santos, Christophe Kolski, Jean Caelen
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part III: Ubiquitous and Intelligent Interaction (2009)

This paper presents a new kind of interaction between users and a tabletop. The table described is interactive and associated with tangible and traceable objects using RFID technology. As a consequence, some Human-Computer Interactions become possible implying these tangible objects. The multi-agent architecture of the table is also explained, as well as a case study based on a scenario.

Authors: Cleriston Araujo Silva, Aristófanes Corrêa Silva, Stelmo Magalhães Netto, Anselmo Cardoso Paiva, Geraldo Braz Junior, Rodolfo Acatauassú Nunes
Venue: Proceedings of the 6th International Conference on Machine Learning and Data Mining in Pattern Recognition (2009)

In this paper, we present the Simpson's Index, a feature used in Spatial Analysis and in Biology, specifically in Ecology to determine the homogeneity or heterogeneity of a certain species. This index will be investigated as a promising feature, since little observation has been done on the application of these features for the analysis of medical images, with three geometrical features, in the characterization of lung nodules as benign or malignant. Using One-Class SVM for classification we obtained sensibility rates of 100%, specificity 100% and accuracy of 100%.
MEMS/microelectronics self-assembly based on analogy of Langmuir-Blodgett approach
Authors: Mei Liu, Yao Lu, Jiangang Zhang, Shanhong Xia, Jun Yang
Venue: Microelectronic Engineering (2009)

A self-assembly method is introduced for the assembly of micro-parts onto Si substrates based on analogy of the Langmuir-Blodgett technique. To perform the assembly, Si substrates are prepared with solder-coated binding sites. The micro-parts are suspended in the butyl acetate-water mixture, and after gentle agitation, the micro-parts form a uniform and well-ordered 2-D aggregate at the butyl acetate-water interface. The micro-parts are attached onto the substrate by passing the substrate vertically through the aggregate of micro-parts. Due to the mechanism of the Langmuir-Blodgett technique, the micro-parts are attached onto the substrate. The butyl acetate-water mixture is then heated to 100^oC, molten solder and air bubbles in the boiling water make it possible for the micro-parts to self-align on the substrate. This methodology could give a self-assembly yield of up to 90%, providing a practicable method for micro-assembly.
A Novel Rate Control Scheme for H.264/AVC Based on Scene Change
Authors: Kan Chang, Bo Yang, Juan Luo
Venue: Proceedings of the 2009 Eigth IEEE/ACIS International Conference on Computer and Information Science (2009)

Scene changes and rapid motion may occur anywhere in a sequence. Commonly, the bit rate of these coded sequences fluctuates and the image quality suffers from severe degradation. If the scene changes and the rapid motion are taken into consideration in bit allocation scheme, the fluctuation of both bit rate and image quality will be reduced. In this work, an intra-frame Rate-Quantization (R-Q) model is presented to better select accurate quantization parameters for intra-coded frames. A rate control scheme for scene changes based on the proposed R-Q model is also discussed. Experiment results show that when employing our proposed scheme, the fluctuation caused by scene change is reduced, and the frame skipped is also avoided with average Peak Signal-to-noise Ratio (PSNR) improved.

Authors: Xingmin Ji
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 01 (2009)

The uncertain nonlinear systems with multiple time delays in system state and control are studied. The systems not only contain uncertainties, but also experience uncertainties in the input channels. The condition for robust stabilizable independent of delay of this kind of systems is presented by using Lyapunov methods. Using solutions of Lyapunov and Riccati equations, a linear state feedback control law is put forward here.

Using Architectural Constraints for Deadlock-Freedom of Component Systems with Multiway Cooperation
Authors: Moritz Martens, Mila Majster-Cederbaum
Venue: Proceedings of the 2009 Third IEEE International Symposium on Theoretical Aspects of Software Engineering (2009)

We present a compositional analysis of deadlock-freedom in component systems with multiway cooperation. We require the systems to satisfy architectural constraints which make sure that the communication structure between the components is given by a tree. Only pairs of components have to be examined for the analysis, therefore the cost is polynomial in the size of the input.
Beyond explicit feedback: new directions in adaptive collaborative learning support
Authors: Erin Walker, Nikol Rummel, Kenneth R. Koedinger
Venue: Proceedings of the 9th international conference on Computer supported collaborative learning - Volume 1 (2009)

Adaptive collaborative learning support (ACLS) may be better than fixed forms of support at increasing learning from collaboration. While much existing adaptive assistance has focused on providing explicit feedback directly to the relevant student, we propose a two-dimensional design space which explores alternative methods of adaptive assistance that are implicit, indirect, or both. We investigated the viability of these ideas using data collected in a classroom evaluation of an ACLS system for peer tutoring which incorporated the design ideas in a manner that provided cognitive support to peer tutors. In this paper, we discuss how students interacted with the different forms of feedback, and propose a second iteration of the assistance that involves collaborative support in addition to domain support.
Grafta: A 3D environment for biomolecular networks
Authors: Peyman Najmabadi, Hans He Lee, Tony Aung, Aung Thuya, Julio Ng, James J. La Clair, Michael D. Burkart
Venue: International Journal of Bioinformatics Research and Applications (2009)

The importance of a comprehensive environment for the depiction of biomolecular networks in the domain of system biology has been emphasised after the completion of genomic, proteomic and metabolomic initatives. Grafta is a software application developed for the three dimensional illustration of biomolecular interactions such as protein interaction networks. Grafta allows its user to move in a 3D environment through a complex assembly of biomolecules represented by 3D objects such as spheres. Their interactions are displayed by an array of 3D tubes. One novelty in Grafta is its anthropomorphic navigation of the viewpoint with respect to the displayed biomolecular network.
A Domain-Driven Approach for Detecting Event Patterns in E-Markets: A Case Study in Financial Market Surveillance
Authors: Piyanath Mangkorntong
Venue:  (2009)

In this research, we look at the problem of detecting complex situations arising in e-markets which have been growing in size rapidly over the past few years. Existing tools available today still cannot overcome the main challenges such as processing a large amount of incoming real-time data from market feeds and the ability to extract data efficiently at a high level. We propose to address these problems using the Event Processing concept and refer to an e-market as a distributed event-driven system, e-market transactions as events and data analysis tools as Event Processing Systems (EPSs). Our solution is based on the new EPS architecture that allows the integration of several existing EPSs (slave EPSs) under a unified domain-specific user interface and execution environment. It also includes the unified e-market data model and event pattern framework for composing and executing event patterns. Selected event patterns used for market surveillance in several stock exchanges have been used in the evaluation process. We sucessfully developed a system prototype using two sophisticated commercial systems, Coral8 and SMARTS, as slave EPSs. The ACM Portal is published by the Association for Computing Machinery.

An Improved Method for Real-Time 3D Construction of DTM
Authors: Yi Wei
Venue: Proceedings of the FIRA RoboWorld Congress 2009 on Advances in Robotics (2009)

This paper discusses the real-time optimal construction of DTM by two measures. One is to improve coordinate transformation of discrete points acquired from lidar, after processing a total number of 10000 data points, the formula calculation for transformation costs 0.810s, while the table look-up method for transformation costs 0.188s, indicating that the latter is superior to the former. The other one is to adjust the density of the point cloud acquired from lidar, the certain amount of the data points are used for 3D construction in proper proportion in order to meet different needs for 3D imaging, and ultimately increase efficiency of DTM construction while saving system resources.

High Capacity Data Hiding in Binary Document Images
Authors: N. B. Puhan, A. T. Ho, F. Sattar
Venue: Proceedings of the 8th International Workshop on Digital Watermarking (2009)

In this paper, we propose a high capacity data hiding method in binary document images towards semi-fragile authentication. Achieving high capacity in binary images with strict imperceptibility criterion is found to be a difficult task. In this method, noise type pixels are selected for pixel-wise data embedding using a secret key. The data hiding process through pixel flipping introduces some background noise in watermarked images and could preserve relevant information. The reversible nature of noise pixel patterns used in flipping process enables blind detection and provides high watermark capacity illustrated in different test images. After extraction process, the background noise is removed to generate the noise-free version of the watermarked image.
