Knowledge Management Guided by Economic Valuation Models
Authors: Stewart A. Sutton, Joseph Betser
Venue: Proceedings of the Third IEEE International Conference on Space Mission Challenges for Information Technology (2009)

We examine Space Mission Knowledge Management (KM), where enterprise knowledge is created by knowledge workers within communities of practice (CoP) and other contributors. We consider the increasing impact of Social Software (SSW) on a modern KM enterprise and regard the difficulty in harmonizing the SSW benefits to the spacemissions enterprise via Web 2.0 and other technologies in conjunction with associated organizational change initiatives. The notion of knowledge tightness is presented, and knowledge markets are compared with capital markets. It is argued that knowledge should be prescriptive, collective, and tight in order to accommodate effective KM. A review of KM activities within The Aerospace Corporation (Aerospace) is provided to illustrate KM applications for National Security Space (NSS).

A lot of tools have been created lately in order to simulate how a vision impaired or color-blind person would perceive web rich-client applications and content. In this work we propose a simulation tool for non-web JavaTM Swing applications. The aim is to assist the developers in preventing accessibility barriers and improving the overall quality throughout the design and implementation phases of the whole development process.
Cross-Sectional Reverse Measurement Technique Research
Authors: Wei Wang, Jun Hong, Yiping Tang
Venue: Proceedings of the 2009 International Conference on Measuring Technology and Mechatronics Automation - Volume 01 (2009)

a new cross-sectional reverse measurement system is proposed in this paper, the common NC milling machine is used in the reverse measurement equipment, which can take full advantage of the existing manufacturing resource and reduce the equipment cost, furthermore, have good performance in measuring the interior shape and size of the objects automatically and accurately. Being a key technique, interpolation for adjacent cross-sections can reduce the distance between adjacent cross-sections, which influences the effect and precision of Cross-Sectional Photogrammetry for Reverse Measurement. Based on linear interpolation method for establishing interpolative-vertex-pair, an improved cross-sectional linear interpolation algorithm is proposed in this paper. The practical applications have verified that this technique can be successfully used in measuring the complex parts with interior shape.

Authors: Emam Hossain, Muhammad Ali Babar, Hye-young Paik
Venue: Proceedings of the 2009 Fourth IEEE International Conference on Global Software Engineering (2009)

There is a growing interest in applying agile practices in Global Software Development (GSD) projects. The literature on using Scrum, one of the most popular agile approaches, in distributed development projects has steadily been growing. However, there has not been any effort to systematically select, review, and synthesize the literature on this topic. We have conducted a systematic literature review of the primary studies that report using Scrum practices in GSD projects. Our search strategy identified 366 papers, of which 20 were identified as primary papers relevant to our research. We extracted data from these papers to identify various challenges of using Scrum in GSD. Current strategies to deal with the identified challenges have also been extracted. This paper presents the review’s findings that are expected to help researchers and practitioners to understand the challenges involved in using Scrum for GSD projects and the strategies available to deal with them.
A New BP Algorithm with Adaptive Momentum for FNNs Training
Authors: Hongmei Shao, Gaofeng Zheng
Venue: Proceedings of the 2009 WRI Global Congress on Intelligent Systems - Volume 04 (2009)

In this paper, a new back propagation (BP) algorithm with adaptive momentum is proposed, where the momentum coefficient is adjusted iteratively based on the current descent direction and the weight increment in the last iteration. A convergence result of the algorithm is presented when it is used for training feed forward neural networks (FNNs) with a hidden layer. Simulation results have shown that this new algorithm has a distinct superiority in fast convergence and smoothing oscillation over the conventional BP method. Moreover, the range for the learning rate has been widened after the inclusion of such an adaptable momentum while maintaining the stability of networks.
A Study of the Multi-objective Evolutionary Algorithm Based on Elitist Strategy
Authors: Chen WenBin, Liu YiJun, Wang Li, Liu XiaoLing
Venue: Proceedings of the 2009 Asia-Pacific Conference on Information Processing - Volume 01 (2009)

To overcome the decrease of diversity of solutions in NSGA II, a multi-objective evolutionary algorithm based on the elitist strategy, a distribution function is proposed here to improve the elitist strategy. By adjusting the parameters of the distribution function and limiting the elitist solutions, some of the non-elitist solutions will be involved in the genetic computation process. The experimental results show that the improved multi-purpose genetic algorithm has a better diversity and faster convergence of solutions than NSGA II.
Design charrettes as pedagogical method in a multimedia design course
Authors: Richard L. Edwards
Venue: Proceedings of the 27th ACM international conference on Design of communication (2009)

Communication design students working in new media or digital media fields require training in the design process to create powerful and professional projects. However, even though collaborative design work is common in media industries, many graduate courses are not structured to allow collaborative work in the classroom. In this paper, I present design charrettes as a pedagogical method that stimulates and supports collaborative student design work. Design charrettes are intense periods of design activity most commonly associated with architectural and environmental studies. I have adapted design charrettes in order to achieve particular learning outcomes in multimedia design courses. This paper is a theoretical reflection on using charrettes to teach the design process. The pedagogy behind my use of charrettes is informed by socio-cognitive learning theories. In my multimedia design courses, graduate students participate in charrette activities to experience the design process, to collaborate in project-based design activities, to seek a range of solutions to design problems, and to gain mastery of design research techniques.
Electronic Health Record as a Knowledge Management Tool in the Scope of Health
Authors: Miguel Angel Montero, Susana Prado
Venue: Knowledge Management for Health Care Procedures: ECAI 2008 Workshop, K4HelP 2008, Patras, Greece, July 21, 2008, Revised Selected Papers (2009)

The concept of knowledge management, introduced by Peter Drucker at the end of the 90s and promoted by figures like Gary Hamel and Coimbatore K Prahalad, is based on the idea that companies must throw themselves into the knowledge of their professionals in order to obtain a competitive advantage in front of their direct competitors, either on costs or on differentiation, and to reach the higher value for the client. In the last years, this conception, linked to the post-capitalist society, is starting to be applied in the scope of health.This requirement is translated on the fact that managers of health centers, regardless of if they are private or public, direct the information systems towards their healthcare professionals, essentially physicians and nurses, since they are the ones who have the knowledge to generate more added value in the patient, which is the ultimate reason of being of any healthcare organization. Electronic Healthcare Record Systems can be considered a subsystem of knowledge management.This paper summarizes the pillars to hold up the knowledge generated within a healthcare organization using the Electronic Health Record as the core element and engine for the more advanced Knowledge Management Systems. The paper compares the most extended market solutions of the healthcare environment in the Spanish national territory.
Influence of Music and Sounds in an Agent-Based Storytelling Environment
Authors: António Leonardo, António Brisson, Ana Paiva
Venue: Proceedings of the 9th International Conference on Intelligent Virtual Agents (2009)

The importance of sound and music in movies (Film Scoring) is undeniable. Film Scoring is used as a complement to the visual content helping to better understand it. The use of these artistic elements can be extended to interactive storytelling (IS) environments where stories are also told in a dynamic and interactive way. Because of IS particularities, such as the unpredictability of user actions and story development, this extension is not straightforward, and presents a problem that needs to be addressed. Further, the presence of autonomous virtual agents makes the creation of these stories more emergent, making difficult the process of creating sounds and music that is adequate. This paper presents a framework that proposes a possible solution to score a story created in these environments by intelligent virtual agents. Additionally, we studied the influence of some particular elements of sound and music (such as tempo, use of different instruments, etc) on the viewers and their perception of the actions of the characters and thus, on the consequent understanding of the story.
The State-of-the-Art in IC Reverse Engineering
Authors: Randy Torrance, Dick James
Venue: Proceedings of the 11th International Workshop on Cryptographic Hardware and Embedded Systems (2009)

This paper gives an overview of the place of reverse engineering (RE) in the semiconductor industry, and the techniques used to obtain information from semiconductor products.The continuous drive of Moore's law to increase the integration level of silicon chips has presented major challenges to the reverse engineer, obsolescing simple teardowns, and demanding the adoption of new and more sophisticated technology to analyse chips. Hardware encryption embedded in chips adds a whole other level of difficulty to IC analysis.This paper covers product teardowns, and discusses the techniques used for system-level analysis, both hardware and software; circuit extraction, taking the chip down to the transistor level, and working back up through the interconnects to create schematics; and process analysis, looking at how a chip is made, and what it is made of. Examples are also given of each type of RE. The paper concludes with a case study of the analysis of an IC with embedded encryption hardware.

Authors: Faizah Shaari, Azuraliza Abu Bakar, Abdul Razak Hamdan
Venue: Proceedings of the 5th International Conference on Advanced Data Mining and Applications (2009)

In this research, a new method to predict and diagnose medical dataset is discovered based on outlier mining method using Rough Sets Theory (RST). The RST is used to generate medical rules, while outliers are detected from the rules to diagnose the abnormal data. In detecting outliers, a computation of set of attributes or known as Non-Reduct is proposed by proposing two new formula of Indiscernibility Matrix Modula(iDMM D) and Indiscernibility Function Modulo (iDMFM D) based on RST. The results show that the proposed method is a fast detection method with lower detection rate. In conclusion, the computation of the Non-Reduct is expected to give medical knowledge that able to predict abnormality in dataset that could be used in medical analysis.

Optimal Transitions for Targeted Protein Quantification: Best Conditioned Submatrix Selection
Authors: Rastislav Šrámek, Bernd Fischer, Elias Vicari, Peter Widmayer
Venue: Proceedings of the 15th Annual International Conference on Computing and Combinatorics (2009)

Multiple reaction monitoring (MRM) is a mass spectrometric method to quantify a specified set of proteins. In this paper, we identify a problem at the core of MRM peptide quantification accuracy. In mathematical terms, the problem is to find for a given matrix a submatrix with best condition number. We show this problem to be NP-hard, and we propose a greedy heuristic. Our numerical experiments show this heuristic to be orders of magnitude better than currently used methods.

Venue: Proceedings of the 5th International Conference on Universal Access in Human-Computer Interaction. Addressing Diversity. Part I: Held as Part of HCI International 2009 (2009)

Cognitive training has been a growing field in recent years. It is established that training improves cognitive abilities in healthy elderly people. Specialized software and commercial devices including the possibility of cognitive gaming has been placed into the market; most of them are based on neuropsychological models of cognitive aging, but few have been scientifically tested. Computerized cognitive games are being developed in "HERMES --- Cognitive Care and Guidance for Active Aging", a research project co-funded by the European Union under the Seventh Framework Program (FP7). Cognitive training designed for HERMES includes daily live events introduced by the user into the system, allowing the stimulation of prospective memory with their own information. Gaming model, concepts and assessment aims (including usability, subjective value and efficacy) are described.
Unitary designs and codes
Authors: Aidan Roy, A. J. Scott
Venue: Designs, Codes and Cryptography (2009)

A unitary design is a collection of unitary matrices that approximate the entire unitary group, much like a spherical design approximates the entire unit sphere. In this paper, we use irreducible representations of the unitary group to find a general lower bound on the size of a unitary t-design in U(d), for any d and t. We also introduce the notion of a unitary code--a subset of U(d) in which the trace inner product of any pair of matrices is restricted to only a small number of distinct absolute values--and give an upper bound for the size of a code with s inner product values in U(d), for any d and s. These bounds can be strengthened when the particular inner product values that occur in the code or design are known. Finally, we describe some constructions of designs: we give an upper bound on the size of the smallest weighted unitary t-design in U(d), and we catalogue some t-designs that arise from finite groups.

Design of a Cache Management Scheme for Gateways on the Vehicular Telematics Network
Authors: Junghoon Lee, In-Hye Shin, Gyung-Leen Park, Ik-Chan Kim, Yoon-Jung Rhee
Venue: Proceedings of the International Conference on Computational Science and Its Applications: Part I (2009)

This paper proposes and measures the performance of a cache management scheme for vehicular telematics network so as to provide an advanced route recommendation service, concentrating on gateways which relay information between a specific server and vehicles. As an enhanced version of pure FAR (Furthest Away Replacement), the proposed scheme 1) replaces Euclidean distance by network distance in estimating the distance to a data item, 2) binds each cache item to a link in the target road network, 3) introduces a directional weight to consider the directional tendency of current traffic flow, and finally 4) schedules the cache requests according to their angular locations to efficiently deal with the multiple pending requests. Simulation results, conducted using the real-life trajectory data obtained from a tracking system currently in operation, show that the proposed scheme can improve the cache hit ratio by up to 9.2 %, compared with FAR as well as that the proposed angle-based scheduling scheme can further improve the cache hit ratio by up to 2.3 %.
An Investigation of the Relationship between Digit Ratio and Spatial Ability
Authors: Hanyu Lin, Moli Yeh, Yenyu Kang
Venue: Proceedings of the 3rd International Conference on Internationalization, Design and Global Development: Held as Part of HCI International 2009 (2009)

Spatial ability plays a key role in many types of reasoning and communication, and is important in domains such as design. Digit ratio is related to a range of cognitive abilities, including spatial ability. In digit ratio studies, most studies were limited by using only one test for spatial ability. The purpose of present study was to investigate which sub-factors of spatial ability are related to digit ratio. We analyzed sex differences and the relationship between digit ratio and three sub-factors of spatial ability. Our results found that right hand digit ratio was significantly lower in males than in females, no significant differences were found between males and females on the left hand ratio. For female samples, both hands digit ratio were significantly negative correlated with perceptual speed factor of spatial ability. There was no association between digit ratio and spatial visualization factor and spatial relation factor.
