Real-time tracking of motor response activation and response competition in a stroop task in young children: A lateralized readiness potential study
Authors: Dénes Szũcs, Fruzsina Soltész, Donna Bryce, David Whitebread
Venue: Journal of Cognitive Neuroscience (2009)

The ability to select an appropriate motor response by resolving competition among alternative responses plays a major role in cognitive performance. fMRI studies suggest that the development of this skill is related to the maturation of the frontal cortex that underlies the improvement of motor inhibition abilities. However, fMRI cannot characterize the temporal properties of motor response competition and motor activation in general. We studied the development of the time course of resolving motor response competition. To this end, we used the lateralized readiness potential (LRP), an ERP measure, for tracking correct and incorrect motor cortex activation in children in real time. Fourteen children and 14 adults took part in an animal-size Stroop task where they selected between two animals, presented simultaneously on the computer screen, which was larger in real life. In the incongruent condition, the LRP detected stronger and longer lasting incorrect response activation in children than in adults. LRP results could explain behavioral congruency effects, the generally longer RT in children than in adults and the larger congruency effect in children than in adults. In contrast, the peak latency of ERP waves, usually associated with stimulus processing speed, could explain neither of the above effects. We conclude that the development of resolving motor response competition, relying on motor inhibition skills, is a crucial factor in child development. Our study demonstrates that the LRP is an excellent tool for studying motor activation in children.

Ontology Design for Online News Analysis
Authors: Biyun Hu, Jun Wang, Yiming Zhou
Venue: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 04 (2009)

News reporting events without people’s review is usually very short, so Vector Space Model (VSM) used for representing long text-based documents is not suitable for describing news. In addition, VSM can not represent basic questions in news: who, what, when, where. A new kind of text model is needed to manipulate news. In this paper, a news ontology incorporating some metadata in OpenCyc,EventsML-G2, NewsML-G2, and News Industry Text Format(NITF) is designed at first. What is more important is that relations in news domain are also described in the ontology. A model for news analysis is then proposed. The process of news analysis is analyzed from three main aspects: instancing, reasoning, and finding similar events. The results indicate that the main benefit of the news ontology is its ability to describe news, reason about news, and deal with the whole process of news analysis.

An Improved Algorithm for Discrete Logarithm Problem
Authors: Jun Zhang, LiQun Chen
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 02 (2009)

The difficulty in solving the discrete logarithm problem (DLP) is very important to the cryptography since it is widely used in signature schemes, message encryption, authentication, and so on. The baby-step giant-step algorithm is a series of well-defined steps to compute the discrete logarithm, but its gigantic storage cost is an obvious disadvantage. The paper designs a new algorithm to compute the discrete logarithm, the method of improved algorithm is similar to the two-dimensional matrix, in which each rows only computes the first value, by this way it can solve DLP. Compare with the original algorithm, the algorithm reduce a lot of time and space spending.
Developing a Scenario Database for Product Innovation
Authors: Shang Hwa Hsu, Jen Wei Chang
Venue: Proceedings of the 1st International Conference on Human Centered Design: Held as Part of HCI International 2009 (2009)

Introducing new product is vital for a company's survival. Scenarios have been demonstrated as a valid tool to generate product ideas from user's perspective. The purpose of this study is to develop a scenario data base for product emergence and a novel method for product idea generation. The proposed scenario database is based on a product innovation database approach that emphasizes on discovering user needs and requirements from scenarios and incorporating them into product development. It draws on the primacy of the idea itself as a driving force toward new product success.
Social-Technical Tools for Collaborative Sensemaking and Sketching
Authors: James Sullivan, Meredith Banasiak, Christopher Messick, Raymond Rimey
Venue: Proceedings of the 13th International Conference on Human-Computer Interaction. Part IV: Interacting in Various Application Domains (2009)

Sensemaking is a deliberate effort to understand events or information, and a sketch is an exploratory graphic composition of a concept or observation. Within the architecture domain, sketching is employed during pre-design phases to create a shared understanding among clients and stakeholders. While sensemaking is highly collaborative, sketching is usually a solitary activity. This paper describes the design and evaluation of two prototype social-technical tools to support collaborative "same time, same place" sketching and sensemaking: (1) a software environment (SketchBook) that allows users to quickly generate and capture ideas; and (2) a wireless, scalable, multi-user pen interface (FireFly). When used together, these tools support simultaneous sketching, diagramming, and annotation within the same work space without traditional bottlenecks of "turn taking" by passing a single pen. This paper presents the motivation for sensemaking and sketching, and findings from a preliminary evaluation involving a design charrette with architecture students.
A Novel Smith Predictor for Wireless Networked Control Systems with Uncertainty
Authors: Feng Du, Wencai Du
Venue: Proceedings of the 2009 International Conference on Environmental Science and Information Application Technology - Volume 03 (2009)

This paper aims at time-variant or uncertain wireless network delay in the wireless networked control systems (WNCS), a new Smith dynamic predictor is proposed.Because new Smith dynamic predictor hides predictor model of the network delay into real transmission process of the network data, further the network delay no longer need to be measured, identified or estimated on-line. It is applicable twosome occasions that wireless network delay is random, time variant or uncertain, possibly large compared to one, even tens sampling periods, at the same time, there are some data dropouts in closed loop. Based on IEEE 802.15.4 (ZigBee), the results of simulation show validity of the compensation scheme in the WNCS, and indicate that system has better dynamic performance and robustness.
Open-Loop Network Design Based on Reverse Logistics Recycling
Authors: Meng Xiangru, Song Wei
Venue: Proceedings of the 2009 IITA International Conference on Services Science, Management and Engineering (2009)

In the early of 1990s, reverse logistics was beginning to be widely concerned by some developed countries, as the government and consumers were more attached importance to environment. China had paid more attention to forward logistics, but there is little concern about reverse logistics. As China entered WTO, companies will be confronted with fierce competition. It is necessary for Chinese companies to set up the product recovery and re-use network. This paper presents solutions to open-loop network designing based on the traditional designing for logistics facility location and capacity allocation model and combined with characteristics of reverse logistics. An optimization model is replied on non-linear programming and the objective is to minimize the sum of investment and operation costs of logistics facilities as well as transportation and environment protection costs of returned products among the facilities. To explain the method for the network of facility location and capacity allocation by the model, an example is presented.
Study of the Relationship between Mus musculus Protein Sequences and Their Biological Functions
Authors: Pawan Seth, Zhong-Hui Duan
Venue: Proceedings of the 2009 WASE International Conference on Information Engineering - Volume 01 (2009)

The central challenge in post-genomic era is to characterize the biological functions of newly discovered proteins. Sequence similarity based approaches infer protein functions based on the homology between proteins. We present the similarity relationship between protein sequences and their functions for mouse (Mus musculus) proteome in the context of gene ontology (GO) slim. The similarity between protein sequences is computed using a measure based on the BLAST alignment scores. The similarity between protein functions is characterized using GO terms. We present the sequence similarity distributions at different levels of the GO tree. The similarities of protein sequences in GO groups residing on different branches of the GO tree are shown. Our results indicate that proteins with similar amino acid sequences tend to have similar biological functions. The posterior probabilities for correct function predictions were also computed. The result reveals certain limitations of the function prediction approaches that are solely based on sequence similarities.
A Hybrid Differential Evolution Method for Practical Engineering Problems
Authors: Jian Li
Venue: Proceedings of the 2009 IITA International Conference on Control, Automation and Systems Engineering (case 2009) (2009)

This paper introduced an almost control parameters free modified differential evolution for global optimization problems. The modifications are derived from the mechanisms of particle swarm optimization viz., topologies, inertial weight, neighborhood best and individual best, with which each individual performed the mutation operator based on its current position, the neighborhood best and its individual best along with the inertial weight. And the crossover operator in traditional differential evolution is removed, while the selection operator was employed. The approach was employed for a tension/compression string design problem and an economic dispatch problem in power system. By comparisons with the other evolutionary algorithms, the proposed approach has shown its feasibility and effectiveness.
Geometric characterization, hydraulic behavior and upscaling of 3D fissured geologic media
Authors: D. Bailly, R. Ababou, M. Quintard
Venue: Mathematics and Computers in Simulation (2009)

In this article, we present numerical modeling and upscaling procedures for highly fissured and discontinuous geologic media, such as 'karsts'. In particular, we propose a geomorphological generation model, and we address the 'upscaling' problem for flow in a highly fissured porous medium ('what is the macroscale hydraulic behavior of the fissured porous medium?'). The morphological model is partly Boolean, based on statistical distributions of discrete objects (voids), combined with a (random) continuum representation for the underlying porous matrix. Various methods for constraining these two types of media are discussed (self-consistent thresholding; genetic dissolution). Hydraulic simulations are then conducted with the 3D finite volume code BIGFLOW, for the case of 3D composite media with constant matrix and high 'fissure/matrix' permeability contrast. The hydrodynamic equations are based on either Darcy's linear head loss law, or on a linear/quadratic combination of Darcy and Ward-Forchheimer quadratic law (inertial effects). The numerical experiments are conducted for saturated steady flow under permeametric boundary conditions. They are used to analyze the equivalent macroscale behavior of fissured media, as well as quasi-percolation effects, in comparison with analytical results and bounds (Darcian case, low Reynolds). In addition, at moderate to large Reynolds numbers, the macroscale effects of non-Darcian (inertial) head losses are also analyzed.
Extracting Decision Correlation Rules
Authors: Alain Casali, Christian Ernst
Venue: Proceedings of the 20th International Conference on Database and Expert Systems Applications (2009)

In this paper, two concepts are introduced: decision correlation rules and contingency vectors. The first concept results from a cross fertilization between correlation and decision rules. It enables relevant links to be highlighted between sets of patterns of a binary relation and the values of target items belonging to the same relation on the twofold basis of the Chi-Squared measure and of the support of the extracted patterns. Due to the very nature of the problem, levelwise algorithms only allow extraction of results with long execution times and huge memory occupation. To offset these two problems, we propose an algorithm based both on the lectic order and contingency vectors, an alternate representation of contingency tables.
Identity Management Design Guide With IBM Tivoli Identity Manager
Venue:  (2009)

Identity Management is the concept of providing a unifying interface to manage all aspects related to individuals and their interactions with the business. It is the process that enables business initiatives by efficiently managing the user lifecycle (including identity/resource provisioning for people (users)), and by integrating into the required business processes. Identity management encompasses all the data and processes related to the representation of an individual involved in electronic transactions. This IBM Redbook provides a methodology for designing an Identity Management solution with IBM Tivoli Identity Manager 4.6. Starting from the high-level, organizational viewpoint we show how to define user registration and maintenance processes using the self-registration and self-care interfaces as well as the delegated administration capabilities. Using the Integrated workflow we will automate the submission/approval processes for identity management requests and with the automated user provisioning we will take workflow output and automatically implement the administrative requests on the environment with no administrative intervention. This book is a valuable resource for security administrators and architects who wish to understand and implement a centralized identity management and security infrastructure.

Integration of a Security Product in Service-Oriented Architecture
Authors: Aleksander Dikanski, Christian Emig, Sebastian Abeck
Venue: Proceedings of the 2009 Third International Conference on Emerging Security Information, Systems and Technologies (2009)

The future of enterprise software development lies in the use of a service-oriented architecture (SOA) to support business concerns. Business services are using security services offered by service-oriented security architectures for security support. The question re¬mains how to implement the security services using traditional security products and how to map security policies defined at service level to product-specific po¬licies. In this paper we present an approach for inte¬grating existing security products into service-oriented security architectures. We show how traditional se¬curity products can be adapted to fit into the overall service-oriented paradigm. We present a case study that applies our approach.
SQL Triggers Reacting on Time Events: An Extension Proposal
Authors: Andreas Behrend, Christian Dorau, Rainer Manthey
Venue: Proceedings of the 13th East European Conference on Advances in Databases and Information Systems (2009)

Being able to activate triggers at timepoints reached or after time intervals elapsed has been acknowledged by many authors as a valuable functionality of a DBMS. Recently, the interest in time-based triggers has been renewed in the context of data stream monitoring. However, up till now SQL triggers react to data changes only, even though research proposals and prototypes have been supporting several other event types, in particular time-based ones, since long. We therefore propose a seamless extension of the SQL trigger concept by time-based triggers, focussing on semantic issues arising from such an extension.
Spectral preprocessing for clustering time-series gene expressions
Authors: Wentao Zhao, Erchin Serpedin, Edward R. Dougherty
Venue: EURASIP Journal on Bioinformatics and Systems Biology (2009)

Based on gene expression profiles, genes can be partitioned into clusters, which might be associated with biological processes or functions, for example, cell cycle, circadian rhythm, and so forth. This paper proposes a novel clustering preprocessing strategy which combines clustering with spectral estimation techniques so that the time information present in time series gene expressions is fully exploited. By comparing the clustering results with a set of biologically annotated yeast cell-cycle genes, the proposed clustering strategy is corroborated to yield significantly different clusters from those created by the traditional expression-based schemes. The proposed technique is especially helpful in grouping genes participating in time-regulated processes.
Impulse invariance-based method for the computation of fractional integral of order 0<α<1
Authors: Youcef Ferdi
Venue: Computers and Electrical Engineering (2009)

This paper presents a simple and efficient method for the design of recursive digital fractional order integrator when the order of integration is a real number between 0 and 1. The proposed method is based on the impulse invariance method. First the initial value theorem is used for the selection of the initial value of the impulse response and then any of the well-established signal modeling techniques can be employed for the parameterization of the discrete impulse response by pole-zero models. For a given model order, the approximation accuracy greatly depends on the initial value selected. Illustrative examples are presented to demonstrate the effectiveness and usefulness of the proposed method.
Transitional environments enhance distance perception in immersive virtual reality systems
Authors: Frank Steinicke, Gerd Bruder, Klaus Hinrichs, Markus Lappe, Brian Ries, Victoria Interrante
Venue: Proceedings of the 6th Symposium on Applied Perception in Graphics and Visualization (2009)

Several experiments have provided evidence that ego-centric distances are perceived as compressed in immersive virtual environments relative to the real world. The principal factors responsible for this phenomenon have remained largely unknown. However, recent experiments suggest that when the virtual environment (VE) is an exact replica of a user's real physical surroundings, the person's distance perception improves. Furthermore, it has been shown that when users start their virtual reality (VR) experience in such a virtual replica and then gradually transition to a different VE, their sense of presence in the actual virtual world increases significantly. In this case the virtual replica serves as a transitional environment between the real and virtual world. In this paper we examine whether a person's distance estimation skills can be transferred from a transitional environment to a different VE. We have conducted blind walking experiments to analyze if starting the VR experience in a transitional environment can improve a person's ability to estimate distances in an immersive VR system. We found that users significantly improve their distance estimation skills when they enter the virtual world via a transitional environment.
