The scientific and information communities have largely mastered the presentation of, and linkages between, text-based electronic information by assigning persistent identifiers to give scientific literature unique identities and accessibility. Knowledge, as published through scientific literature, is often the last step in a process originating from scientific research data. Today scientists are using simulation, observational, and experimentation techniques that yield massive quantities of research data. These data are analyzed, synthesized, interpreted, and the outcome of this process is generally published as a scientific article. Access to the original data as the foundation of knowledge has become an important issue throughout the world and different projects have started to find solutions. Global collaboration and scientific advances could be accelerated through broader access to scientific research data. In other words, data access could be revolutionized through the same technologies used to make textual literature accessible. The most obvious opportunity to broaden visibility of and access to research data is to integrate its access into the medium where it is most often cited: electronic textual information. Besides this opportunity, it is important, irrespective of where they are cited, for research data to have an internet identity. Since 2005, the German National Library of Science and Technology (TIB) has offered a successful Digital Object Identifier (DOI) registration service for persistent identification of research data. In this white paper we discuss the possibilities to open this registration to a global consortium of information institutes and libraries.

Multimedia data is always exposed for the security threats, because these data can be easily alter by using multimedia data processing tools. Therefore content owners always endure of copyright protection and ownership verification of their digital assets. Digital watermarking is the technology introduces to overcome these limitations. There are different watermarking technologies which focusing different security aspects. Proving the authenticity of digital multimedia data, the watermarking concept was commenced called Fragile Watermarking. However, evolution of the fragile watermark derives a prospective watermarking concept called semi-fragile watermark, which overcomes several limitations of fragile watermarking such as fragility for trusted image manipulations. Multimedia data consisted huge amount of information; however, most of them are not in the perceptible region of Human Visual System (HVS). In this paper, we presented an experiment that quantifies the perceptible information perceived in DCT domain and a new PKI (Public Key Infrastructure) based semi-fragile watermarking technique that quantitatively authenticates perceptible content of the digital images. Additionally, our definition localizes the compromised regions of the image. The proposed method inherits all security features in public key authentication system. In practice, visual distortions are acceptable up to some extent in digital multimedia applications. Therefore, distortions due to the watermark should be minimized. Moreover, this paper presents a critical analysis of the parameterization of watermark embedding technique and its analysis matrices (graphs & tables), which can be used to optimize the watermarking method according to the user’’s requirements.

Authors: Liu Jun, Yan Zhiqiang, Qiao Jianzhong, Lin Shukuan
Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 03 (2009)

Last decade has proven a drastic change in information technology. Service Oriented Architecture (SOA), as a new generation of software technique, comes into being to face the challenge of the soaring business varieties and complexities. This paper offers a discussion of service properties and appoints 6 key service properties for SOA. Then, the paper puts forward a role-based reference model for SOA to detail how SOA ensure these properties by service roles and elements. The model is divided into static part and dynamic part: static model describes elements of service roles and files; dynamic model illustrates 6 kinds of interactions between service roles. At last, the paper summarizes the static model, dynamic model and their relationships.
Understanding the effects of requirements volatility in software engineering by using analytical modeling and software process simulation
Authors: Susan Ferreira, James Collofello, Dan Shunk, Gerald Mackulak
Venue: Journal of Systems and Software (2009)

This paper introduces an executable system dynamics simulation model developed to help project managers comprehend the complex impacts related to requirements volatility on a software development project. The simulator extends previous research and adds research results from an empirical survey, including over 50 new parameters derived from the associated survey data, to a base model. The paper discusses detailed results from two cases that show significant cost, schedule, and quality impacts as a result of requirements volatility. The simulator can be used as an effective tool to demonstrate the complex set of factor relationships and effects related to requirements volatility.
Extending network lifetime for ALLIANCES
Authors: Xinhua Yang, Tracy Camp, Hailong Yang, Athina P. Petropulu
Venue: Computer Communications (2009)

ALLIANCES is a newly proposed wireless MAC protocol that exploits the cooperation of source nodes and relay nodes to resolve collisions and further improve throughput. Until now, ALLIANCES did not consider energy, which is the most precious commodity of mobile communications. In this paper, we propose an energy-conserving version of ALLIANCES that introduces a sleep state. Our analytical results show that the energy-conserving model can save at least 54% of energy consumption when compared to the original energy model (referred to as the basic energy model in this paper). Because a relay selection scheme is a significant piece of ALLIANCES, directly affecting the throughput and the energy distribution, we also propose an energy-aware relay selection scheme (ERS). ERS maintains the performance benefits of the previously proposed location relay selection scheme (LRS), but more evenly distributes the amount of energy remaining throughout the network. We implement our energy-conserving model and ERS in the popular network simulator (NS-2) to evaluate and compare the energy remaining at each node and the network's throughput when using LRS and ERS. Simulation results show that the energy-conserving model can save up to 80% of energy without nodes taking longer to communicate. In addition, using the energy-conserving model, ERS provides 23.3% longer lifetime of the network than LRS, without noticeable throughput degradation.

Authors: Hironobu Kamimura, Noriaki Kaneki, Kohji Shimada, Hauki Sasaki
Venue: Proceedings of the 2009 International Conference on Biometrics and Kansei Engineering (2009)

This research examined the effect of different odors and different types of breathing on the recovery period after moderate exercise on bicycle. The subjects were nine healthy college students (male). The experiment was divided into three periods. The first was the baseline period of six minutes during which the students remained seated. During the second period the students exercised for twelve minutes on an exercise bike. In the final period, lasting twelve minutes, the students were seated again during which time they were exposed to a number of different odors. Students' breathing was also varied and checked, the breathing divided into either students' natural breathing cycle, or inhalation through the nose and exhalation through the mouth. Odors rated 'pleasant' by the students did not result in any changes in their respiratory metabolism. However, exposure to unpleasant odors resulted in significant change in the respiratory metabolism during the recovery period. The results of the experiment suggest that the exposure to an unpleasant odor, combined with breathing in through the nose and out through the mouth, had a notable effect on the student's respiratory metabolism.

Authors: Mohanad Al-Jabari, Michael Mrissa, Philippe Thiran
Venue: Proceedings of the 17th International Conference on User Modeling, Adaptation, and Personalization: formerly UM and AH (2009)

Web usability has been considered as a key issue to the success of the Web. However, Web readers typically face difficulties since Web pages are presented according to the local contexts of Web authors. Web authors and readers follow their own local contexts to represent and interpret Web contents as they originate from different communities. Hence, there is a need to transform Web contents created according to the authors' contexts into the different contexts of their readers.In this paper, we aim at presenting a solution that provides Web contents according to the reader's context. Our solution is based on an explicit representation of the authors' and readers' local contexts. We rely on RDFa to annotate contents with the author's context and we provide an adaptation process on the client-side that generates contextualized Web contents according to the readers' contexts. We validate our approach through a Firefox extension.

Issues in reasoning about interaction networks in cells: necessity of event ordering knowledge
Authors: Nam Tran, Chitta Baral, Carron Shankland
Venue: Proceedings of the 20th national conference on Artificial intelligence - Volume 2 (2005)

In this paper we discuss several representation issues that we came across while modelling molecular interactions in cells of living organisms. One of the issues was that the triggering of events inside cells, an important modelling component, are not necessarily immediate, leading to multiple evolution models in the absence of additional information. Second, often an action or a trigger at one level of granularity of representation can be elaborated and refined. We show the problem that existing representation and modelling formalisms have in dealing with the above issues. We then present an action language which builds up on a previous language, and has the ability to express event ordering knowledge. We show that our language is able to adequately address the above-mentioned issues.

Venue: Proceedings of the 2009 International Forum on Information Technology and Applications - Volume 01 (2009)

Virtual city is an important part of the digital city, and it is an important way to show the information of three-dimensional of a city. Acting as the virtual environment platform for the "global information system" and the development of digital cities, virtual city plays a core role in urban planning, real estate, community management, as well as city tourism, urban construction, and so on. VRML is an opening standard for describing the interactive 3D multimedia on Internet and sharing the virtual world. This paper does some research on the application of VRML in constructing virtual city. It discusses the basic function of VRML and the basic frame of virtual world based on VRML, and also gives an application instance of virtual city scene. Finally, it summarizes some technology and methods in constructing virtual city with VRML.

Venue: Proceedings of the 20th national conference on Innovative applications of artificial intelligence - Volume 3 (2008)

Despite its centrality to Chinese culture and wide adoption in Chinese communities, Traditional Chinese Medicine (TCM) has rarely been the application domain of computational analysis in previous academic works. Here we present the first systematic adoption of the state-of-the-art Semantic Web technologies in the codification, management, and utilization of TCM information and knowledge resources. These technologies are proved effective in bridging the semantic gaps between a plurality of legacy and heterogeneous relational databases, enabling ontology-based query and search across database boundaries. A global herb-drug interaction network is constructed and represented in Semantic Web language, on which the semantic graph mining methodology is applied for discovering and interpreting interesting patterns. This deployed Semantic Web platform provides various innovative information retrieval and knowledge discovery services to the TCM domain experts with positive feedbacks. This project demonstrates Semantic Web's advantages in connecting data across domain and community boundaries to facilitate interdisciplinary and cross-cultural studies.
Compact non-binary fast adders using single-electron devices
Authors: Wancheng Zhang, Nan-Jian Wu
Venue: Microelectronics Journal (2009)

This paper proposes compact adders that are based on non-binary redundant number systems and single-electron (SE) devices. The adders use the number of single electrons to represent discrete multiple-valued logic state and manipulate single electrons to perform arithmetic operations. These adders have fast speed and are referred as fast adders. We develop a family of SE transfer circuits based on MOSFET-based SE turnstile. The fast adder circuit can be easily designed by directly mapping the graphical counter tree diagram (CTD) representation of the addition algorithm to SE devices and circuits. We propose two design approaches to implement fast adders using SE transfer circuits: the threshold approach and the periodic approach. The periodic approach uses the voltage-controlled single-electron transfer characteristics to efficiently achieve periodic arithmetic functions. We use HSPICE simulator to verify fast adders operations. The speeds of the proposed adders are fast. The numbers of transistors of the adders are much smaller than conventional approaches. The power dissipations are much lower than CMOS and multiple-valued current-mode fast adders.
Speech emotion recognition with TGI+.2 classifier
Authors: Julia Sidorova
Venue: Proceedings of the 12th Conference of the European Chapter of the Association for Computational Linguistics: Student Research Workshop (2009)

We have adapted a classification approach coming from optical character recognition research to the task of speech emotion recognition. The classification approach enjoys the representational power of a syntactic method and efficiency of statistical classification. The syntactic part implements a tree grammar inference algorithm. We have extended this part of the algorithm with various edit costs to penalise more important features with higher edit costs for being outside the interval, which tree automata learned at the inference stage. The statistical part implements an entropy based decision tree (C4.5). We did the testing on the Berlin database of emotional speech. Our classifier outperforms the state of the art classifier (Multilayer Perceptron) by 4.68% and a baseline (C4.5) by 26.58%, which proves validity of the approach.
Minimizing mobile phone disruption via smart profile management
Authors: Amnon Dekel, Dan Nacht, Scott Kirkpatrick
Venue: Proceedings of the 11th International Conference on Human-Computer Interaction with Mobile Devices and Services (2009)

In this paper, we describe the Smart Profile Management application that was designed to help minimize mobile phone disruptions. The system achieves the goal using a machine learning based algorithm that switches the phone profile automatically. A prototype was developed in Python for S60 and an informal usability test was run for a period of 7 days. Results show that a large proportion of profile suggestion changes were accepted by subjects, suggesting that such an application can in fact lower disruptions.
Location-Based Services and Privacy in Airports
Authors: John Paulin Hansen, Alexandre Alapetite, Henning Boje Andersen, Lone Malmborg, Jacob Thommesen
Venue: Proceedings of the 12th IFIP TC 13 International Conference on Human-Computer Interaction: Part I (2009)

This paper reports on a study of privacy concerns related to location-based services in an airport, where users who volunteer for the service will be tracked for a limited period and within a limited area. Reactions elicited from travellers at a field trial showed 60% feeling to some or to a large degree more secure with the system in operation. To provide a background for the privacy study we also describe services provided by the tracking facility and the infrastructure behind it as well as the design and evaluation activities we used. Based on project results including a large number of comments from passengers, we discuss factors influencing passengers' acceptance and appreciation of location-based services in airports.
Active mobile robot localization
Authors: Wolfram Burgard, Dieter Fox, Sebastian Thrun
Venue: Proceedings of the Fifteenth international joint conference on Artifical intelligence - Volume 2 (1997)

Localization is the problem of determining the position of a mobile robot from sensor data. Most existing localization approaches are passive, i.e., they do not exploit the opportunity to control the robot's effectors during localization. This paper proposes an active localization approach. The approach provides rational criteria for (1) setting the robot's motion direction (exploration), and (2) determining the pointing direction of the sensors so as to most efficiently localize the robot. Furthermore, it is able to deal with noisy sensors and approximative world models. The appropriateness of our approach is demonstrated empirically using a mobile robot in a structured office environment.
Some constructions of the join of fuzzy subgroups and certain lattices of fuzzy subgroups with sup property
Authors: Naseem Ajmal, Aparna Jain
Venue: Information Sciences: an International Journal (2009)

In this paper, some new lattices of fuzzy substructures are constructed. For a given fuzzy set @m in a group G, a fuzzy subgroup S(@m) generated by @m is defined which helps to establish that the set L"s of all fuzzy subgroups with sup property constitutes a lattice. Consequently, many other sublattices of the lattice L of all fuzzy subgroups of G like L"s"""t,L"s"""n,L"s"""n"""""""t, etc. are also obtained. The notion of infimum is used to construct a fuzzy subgroup i(@m) generated by a given fuzzy set @m, in contrast to the usual practice of using supremum. In the process a new fuzzy subgroup i(@m)^* is defined which we shall call a shadow fuzzy subgroup of @m. It is established that if @m has inf property, then i(@m)^* also has this property.
Towards a Module System for K
Authors: Mark Hills, Grigore Roşu
Venue: Recent Trends in Algebraic Development Techniques: 19th International Workshop, WADT 2008, Pisa, Italy, June 13-16, 2008, Revised Selected Papers (2009)

Research on the semantics of programming languages has yielded a wide array of notations and methodologies for defining languages and language features. An important feature many of these notations and methodologies lack is modularity: the ability to define a language feature once, insulating it from unrelated changes in other parts of the language, and allowing it to be reused in other language definitions. This paper introduces ongoing work on modularity features in K, an algebraic, rewriting logic based formalism for defining language semantics.

Reducing working memory load in spoken dialogue systems
Authors: Maria Wolters, Kallirroi Georgila, Johanna D. Moore, Robert H. Logie, Sarah E. MacPherson, Matthew Watson
Venue: Interacting with Computers (2009)

We evaluated two strategies for alleviating working memory load for users of voice interfaces: presenting fewer options per turn and providing confirmations. Forty-eight users booked appointments using nine different dialogue systems, which varied in the number of options presented and the confirmation strategy used. Participants also performed four cognitive tests and rated the usability of each dialogue system on a standardised questionnaire. When systems presented more options per turn and avoided explicit confirmation subdialogues, both older and younger users booked appointments more quickly without compromising task success. Users with lower information processing speed were less likely to remember all relevant aspects of the appointment. Working memory span did not affect appointment recall. Older users were slightly less satisfied with the dialogue systems than younger users. We conclude that the number of options is less important than an accurate assessment of the actual cognitive demands of the task at hand.
