Efficient top-k algorithms for fuzzy search in string collections
Authors: Rares Vernica, Chen Li
Venue: Proceedings of the First International Workshop on Keyword Search on Structured Data (2009)

An approximate search query on a collection of strings finds those strings in the collection that are similar to a given query string, where similarity is defined using a given similarity function such as Jaccard, cosine, and edit distance. Answering approximate queries efficiently is important in many applications such as search engines, data cleaning, query relaxation, and spell checking, where inconsistencies and errors exist in user queries as well as data. In this paper, we study the problem of efficiently computing the best answers to an approximate string query, where the quality of a string is based on both its importance and its similarity to the query string. We first develop a progressive algorithm that answers a ranking query by using the results of several approximate range queries, leveraging existing search techniques. We then develop efficient algorithms for answering ranking queries using indexing structures of gram-based inverted lists. We answer a ranking query by traversing the inverted lists, pruning and skipping irrelevant string ids, iteratively increasing the pruning and skipping power, and doing early termination. We have conducted extensive experiments on real datasets to evaluate the proposed algorithms and report our findings.
A new parallel link interface with current-mode incremental signaling and per-pin skew compensation
Authors: An Hu, Fei Yuan
Venue: Analog Integrated Circuits and Signal Processing (2009)

This paper proposes a new current-mode incremental signaling parallel link interface with per-pin skew compensation. Per-pin skew compensation is carried out in a calibration phase where clock-like training data are sent to all channels along with a reference clock of the same frequency. Training data are deskewed with respect to the common reference clock using DLLs such that all channels are skew-compensated simultaneously. New encoding and decoding scheme have been proposed to reduce the signal critical path at the transmitter. Transimpedance amplifiers with replica biasing are used to perform current-to-voltage conversion at the receiving end with a minimum sensitivity to supply voltage fluctuation. To evaluate the performance of the proposed skew compensating technique, a 1 Gbytes/s parallel link interface consisting of two data channels and one reference clock channel has been implemented with UMC 0.13 μm 1.2 V CMOS technology and analyzed using SpectreRF from Cadence Design Systems with BIM3V3 device models. The channels are modeled as 50 ¿ microstrip lines on a FR-4 substrate. Simulation results of the parallel link at all process corners have demonstrated that the proposed parallel link interface provides a minimum deskew range of 1.2 ns (±0.6 ns in each direction).
Working with search results
Authors: Jamie Starke, Chris Luce, Jonathan Sillito
Venue: Proceedings of the 2009 ICSE Workshop on Search-Driven Development-Users, Infrastructure, Tools and Evaluation (2009)

Source code search is an important activity for programmers working on a change task to a software system. We are at the early stages of a research program that is aiming to answer three research questions: (1) How effectively can programmers express (using today's tools) the information they are seeking? (2) How effectively can programmers determine which of the matches returned from their searches are relevant to their task? and (3) In what ways can tools be improved to support programmers in more effectively expressing their information needs and exploring the results of searches? To begin answering these questions we have conducted a study in which we gathered both qualitative and quantitative data about programmers' search activities. Our analysis of this data is still incomplete, however this paper presents several of our initial observations about how programmers interact with the results from their searches.
Computational measures for language similarity across time in online communities
Authors: David Huffaker, Joseph Jorgensen, Francisco Iacobelli, Paul Tepper, Justine Cassell
Venue: Proceedings of the HLT-NAACL 2006 Workshop on Analyzing Conversations in Text and Speech (2006)

This paper examines language similarity in messages over time in an online community of adolescents from around the world using three computational measures: Spearman's Correlation Coefficient, Zipping and Latent Semantic Analysis. Results suggest that the participants' language diverges over a six-week period, and that divergence is not mediated by demographic variables such as leadership status or gender. This divergence may represent the introduction of more unique words over time, and is influenced by a continual change in subtopics over time, as well as community-wide historical events that introduce new vocabulary at later time periods. Our results highlight both the possibilities and shortcomings of using document similarity measures to assess convergence in language use.

A user-friendly metadata quality control tool for the internet public library
Authors: Michael Khoo, Xia Lin, Jung-ran Park
Venue: Proceedings of the 9th ACM/IEEE-CS joint conference on Digital libraries (2009)

The Internet Public Library (IPL) is crosswalking its metadata to Dublin Core. The quality of the crosswalked metadata will be unknown. The IPL is therefore developing a tool for metadata quality control suitable for use by LIS students who have little previous metadata quality control experience.
Maximizing network lifetime based on transmission range adjustment in wireless sensor networks
Authors: Chao Song, Ming Liu, Jiannong Cao, Yuan Zheng, Haigang Gong, Guihai Chen
Venue: Computer Communications (2009)

In a wireless sensor network (WSN), the unbalanced distribution of communication loads often causes the problem of energy hole, which means the energy of the nodes in the hole region will be exhausted sooner than the nodes in other regions. This is a key factor which affects the lifetime of the networks. In this paper we propose an improved corona model with levels for analyzing sensors with adjustable transmission ranges in a WSN with circular multi-hop deployment (modeled as concentric coronas). Based on the model we consider that the right transmission ranges of sensors in each corona is the decision factor for optimizing the network lifetime after nodes deployment. We prove that searching optimal transmission ranges of sensors among all coronas is a multi-objective optimization problem (MOP), which is NP hard. Therefore, we propose a centralized algorithm and a distributed algorithm for assigning the transmission ranges of sensors in each corona for different node distributions. The two algorithms can not only reduce the searching complexity but also obtain results approximated to the optimal solution. Furthermore, the simulation results of our solutions indicate that the network lifetime approximates to that ensured by the optimal under both uniform and non-uniform node distribution.

Authors: Andreas Apostolakis, Dimitris Gizopoulos, Mihalis Psarakis, Danilo Ravotto, Matteo Sonza Reorda
Venue: IEEE Design Test (2009)

Testing communication peripherals in an environment of systems on a chip is particularly challenging. The authors explore two test program generation approaches&#x2014;one fully automated and one deterministically guided&#x2014;and propose a novel combination of the two schemes that can be applied in a generic manner on a wide set of communication cores.
Flexible deadlines for directed obligations in agent-based business contracts
Authors: Henrique Lopes Cardoso, Eugénio Oliveira
Venue: Proceedings of The 8th International Conference on Autonomous Agents and Multiagent Systems - Volume 2 (2009)

In B2B contract enactment, cooperation should be taken into account when modeling contractual commitments through obligations. We advocate a directed deadline obligation approach, taking inspiration on international legislation over trade procedures. Our proposal is based on authorizations granted in specific states of an obligation lifecycle model. Flexible deadlines provide an additional level of cooperation between contractual agents. Moreover, agents increase their decision-making options concerning obligations.
The Sile Model -- A Semantic File System Infrastructure for the Desktop
Authors: Bernhard Schandl, Bernhard Haslhofer
Venue: Proceedings of the 6th European Semantic Web Conference on The Semantic Web: Research and Applications (2009)

With the increasing storage capacity of personal computing devices, the problems of information overload and information fragmentation become apparent on users' desktops. For the Web, semantic technologies aim at solving this problem by adding a machine-interpretable information layer on top of existing resources, and it has been shown that the application of these technologies to desktop environments is helpful for end users. Certain characteristics of the Semantic Web architecture that are commonly accepted in the Web context, however, are not desirable for desktops; e.g., incomplete information, broken links, or disruption of content and annotations. To overcome these limitations, we propose the sile model, an intermediate data model that combines attributes of the Semantic Web and file systems. This model is intended to be the conceptual foundation of the Semantic Desktop, and to serve as underlying infrastructure on which applications and further services, e.g., virtual file systems, can be built. In this paper, we present the sile model, discuss Semantic Web vocabularies that can be used in the context of this model to annotate desktop data, and analyze the performance of typical operations on a virtual file system implementation that is based on this model.
Sustainable business and environmental indicators
Authors: Uros Ogrin, Davorin Kralj
Venue: WSEAS TRANSACTIONS on COMMUNICATIONS (2009)

This article focuses primarily on the research in Sustainable Business and Environmental Indicators of 120 Slovenian companies, in view of a general environmental management model. The research for this paper is based on the collection and analysis of quantitative and qualitative data. From research results, we can conclude that at a declarative level, environmental care is reflected in leadership and policy, strategy and organizational culture in the area of environmental management, where as the actual care is implemented in the processes related to this area. System thinking and multi view approaches, which are a must for a successful establishment of a sustainable business and environmental indicators, are of great importance. It is essential for the real effectiveness of environmental management to have appropriate leadership and keep well-regulated interpersonal relations in an enterprise. Congenial and stimulating atmosphere, promoting relaxed free and unimpeded activities, work satisfaction and satisfaction with co-operation with others, are all elements distinguishing excellent performance. When implementing changes, employees should be motivated adequately. Environmental indicators are powerful tools that serve many purposes, useful as tools for performance evaluation and public information. The development of indicators is a dynamic process that is constantly subject to updating and improvement.
The promise of solid state disks: increasing efficiency and reducing cost of DBMS processing
Authors: Karsten Schmidt, Yi Ou, Theo Härder
Venue: Proceedings of the 2nd Canadian Conference on Computer Science and Software Engineering (2009)

Most database systems (DBMSs) today are operating on servers equipped with magnetic disks. In our contribution, we want to motivate the use of two emerging and striking technologies, namely native XML DBMSs (XDBMSs for short) and solid state disks. In this context, the traditional read/write model optimized by a sophisticated cache hierarchy and the IO cost model for databases needs adjustment. Such new devices together with optimized storage mapping of XML documents provide a number of challenging characteristics. We discuss howtheir optimization potential ca be exploited to enhance transactional DB performance under reduced energy consumption to match increasing application demands and, at the same time, to guarantee economic energy use in data centers.

Two-handed drawing on augmented desk system
Authors: Xinlei Chen, Hideki Koike, Yasuto Nakanishi, Kenji Oka, Yoichi Sato
Venue: Proceedings of the working conference on Advanced visual interfaces (2002)

This paper describes a two-handed drawing tool developed on our augmented desk system. Using our real-time finger tracking method, a user can draw and manipulate objects interactively by his/her own finger/hand. Based on the former work on two-handed interaction, different roles are assigned to each hand. The right hand is used to draw and to manipulate objects. Using gesture recognition, primitive objects can be drawn by users' handwriting. On the other hand, the left hand is used to manipulate menus and to assist the right hand. By closing all left hand fingers, users can initiate the appearance of structural radial menus around their left hands, and can select appropriate items by using a left hand finger. The left hand is also used to assist in the performance of drawing tasks, e.g., specifying the center of a circle or top-left corner of a rectangle, or specifying the object to be copied.
Approximate solution of hyperbolic conservation laws by discrete mollification
Authors: Carlos D. Acosta, Carlos E. Mejía
Venue: Applied Numerical Mathematics (2009)

We consider explicit schemes for the numerical solution of one dimensional linear and nonlinear hyperbolic conservation laws. We show that the combination of these methods with discrete mollification, yields new methods with the following characteristics: Larger time steps are allowed and stability is preserved. Furthermore, they can be implemented in such a way that nonoscillatory solutions are obtained. We include theoretical results and a well selected set of encouraging numerical experiments.
Adaptation-aware encryption of scalable H.264/AVC video for content security
Authors: H. Kodikara Arachchi, X. Perramon, S. Dogan, A. M. Kondoz
Venue: Image Communication (2009)

Data encryption is one of the key information security technologies used for safeguarding multimedia content from unauthorised access and manipulation in end-to-end delivery and access chains. This technology, combined with the appropriate cryptographic methods, effectively prevents the content against malicious attacks, so as to protect its authenticity as well as integrity. While encryption-based security is ensuring the authorised consumption of the multimedia content, content adaptation technologies have the primary goal of providing means for wider dissemination of the content across diverse networks, devices and users, and thus enriching user satisfaction and experience of the delivered content within a given set of usage environment constraints. Traditionally, protected contents can only be adapted at trusted adaptation engines residing between the source and end-users, since they have to be fully decrypted before performing the necessary adaptation operations. The drawback of such a process is that it significantly limits the availability and flexibility of adaptation engines applicable for adapting protected contents on the fly. Thus, this paper proposes a novel scalable H.264/advanced video coding (AVC)-compatible video encryption technique, which is also transparent to adaptation engines in an end-to-end video delivery scenario. The proposed technology relies on keeping syntax elements required for performing the adaptation operations clear (i.e., not encrypted). The effectiveness of the proposed technique has been successfully verified in scenarios, where both conventional joint scalable video model (JSVM) bit stream extracting and random packet dropping mechanisms are used.
Increasing the Attractiveness of Mass Customization: The Role of Complementary On-line Services and Range of Options
Authors: Benedict Dellaert, Pratibha Dabholkar
Venue: International Journal of Electronic Commerce (2009)

This study investigates the antecedents of consumer intentions to use mass customization on the Internet and the joint role of complementary on-line services (visualization, salesperson interaction, and post-purchase product adaptation) and the range of mass customization options in on-line mass customization. It extends past research by demonstrating that perceptions of control and enjoyment, in addition to perceptions of product outcome and complexity, have a strong impact on consumer intentions to use an on-line mass customization process. The study finds that both increasing the range of mass customization options and providing complementary on-line services enhance perceptions of product outcome, control, and enjoyment in using an on-line mass customization process. However, in contrast to the range of mass customization options, complementary on-line services can be increased without increasing the perceived complexity of the process. Finally, perceived control mediates the negative effect of perceived complexity on consumer intentions to use on-line mass customization.
Taking advantage of the Semantics of a Lesson Graph based on Learning Objects
Authors: Olivier Motelet, Nelson Baloian, Benjamin Piwowarski, José A. Pino
Venue: Proceeding of the 2007 conference on Artificial Intelligence in Education: Building Technology Rich Learning Contexts That Work (2007)

Lesson graphs are composed of Learning Objects (LOs) and include a valuable amount of information about the content and usage of the LOs, described by the LO metadata. Graphs also make explicit the links between the LOs (i.e. the graph semantics). This article proposes a conceptual model for taking advantage of this information. This model is based on an original diffusion process that copes with the problem of lesson graphs where some metadatas are missing. Two applications of the model are described and were implemented over a previously developed lesson authoring tool whose goal is to facilitate the lesson authoring process.
Highly parity linked graphs
Authors: Ken-Ichi Kawarabayashi, Bruce Reed
Venue: Combinatorica (2009)

A graph G is k-linked if G has at least 2k vertices, and for any 2k vertices x 1,x 2, &#x2026;, x k ,y 1,y 2, &#x2026;, y k , G contains k pairwise disjoint paths P 1, &#x2026;, P k such that P i joins x i and y i for i = 1,2, &#x2026;, k. We say that G is parity-k-linked if G is k-linked and, in addition, the paths P 1, &#x2026;, P k can be chosen such that the parities of their length are prescribed. Thomassen [22] was the first to prove the existence of a function f(k) such that every f(k)-connected graph is parity-k-linked if the deletion of any 4k-3 vertices leaves a nonbipartite graph. In this paper, we will show that the above statement is still valid for 50k-connected graphs. This is the first result that connectivity which is a linear function of k guarantees the Erd&#x0151;s-P&#x00f3;sa type result for parity-k-linked graphs.

Venue: Proceedings of the 7th WSEAS international conference on System science and simulation in engineering (2008)

The aim of this paper is to introduce a method of combining two different Weibull distributions. This method illustrates on how to produce a mixture distribution based on two Weibull distributions by including a mixing parameter, say w, which represents the proportion of mixing associated to the two component models. Weibull distributions. The mixture distribution produced from the combination of two Weibull distributions has a number of parameters which include shape parameters, scale parameters and location parameters in addition to the mixing parameter. In this paper, we focus on the estimation of parameters of the proposed mixture Weibull distribution using maximum likelihood method. In addition, we illustrate the characteristics of this distribution in terms of the probability density function, cumulative distribution function, reliability function and failure rate for a particular value of w.
A freight management system with the ambient calculus
Authors: Toru Kato, Masahiro Higuchi
Venue: Proceedings of the 8th Wseas international conference on Telecommunications and informatics (2009)

We investigate a management system that ensures the correctness of cargo distribution in freight systems. The system determines the correctness by comparing the movement of containers, which is sensed by IC tags with formal models. These models are written in the ambient calculus and generated automatically based on several documents used in real freight systems. The ambient calculus is a formal description language that is suitable for representing freight systems with nested structures that dynamically change. An implementation of the system and the results of a simple experiment using it are presented.
