Venue: Proceedings of the 2nd conference on European computing conference (2008)

Dynamic analyses of the landing gear are conducted to provide capabilities to forecast their behavior under hazardous conditions. This kind of investigation with numerical methods implementation is much easier and less expensive than stand tests. The major advantage of the presented numerical method is applicability to landing gear tests with artificially introduced flaws.
Knowledge awareness in CSCL: A psychological perspective
Authors: Tanja Engelmann, Jessica Dehler, Daniel Bodemer, Jürgen Buder
Venue: Computers in Human Behavior (2009)

In this paper, a specific group awareness approach for CSCL settings, namely knowledge awareness, is presented. We classify knowledge awareness in relation to already well-established concepts like shared mental models, common ground, and transactive memory system in order to provide a comprehensive definition of this approach. The functionality of knowledge awareness tools aiming at fostering knowledge awareness is conceptualized in a cyclical model. Three application scenarios are presented to illustrate how knowledge awareness tools work in three different tasks. All these knowledge awareness tools have been found to be effective, that is all tools could foster knowledge awareness and led to increased learning performance.
Assessing and Scaffolding Collaborative Learning in Online Discussions
Authors: Erin Shaw
Venue: Proceeding of the 2005 conference on Artificial Intelligence in Education: Supporting Learning through Intelligent and Socially Informed Technology (2005)

In this paper we present two computational approaches that can be used characterize and measure online threaded discussions and demonstrate that they can objectively validate student-reported differences in collaborative learning between tutor-scaffolded and non-scaffolded discussion activities. The first approach, thread profiling, is used to characterize user interactions that tend to broaden and deepen discussions, and gives insight into how tutors participate in discussions. The second approach, which uses a natural language discourse processor, is used to compare the rhetoric of tutors and students, and shows that tutors consistently use more attributions, elaborations, and enablements to scaffold discussions. To test these ideas we processed twenty-four online activities, constituting over one thousand message posts, during a course at the British Open University. These computational methods and findings have application in virtual tutoring systems and the automated assessment of discussions.

A Three-dimensional Context-awareness Model: Support Learning Services Providing in e-Learning Environments
Authors: Yanlin Zheng, Luyi Li, Hiroaki Ogata, Yoneo Yano
Venue: Proceeding of the 2005 conference on Towards Sustainable and Scalable Educational Innovations Informed by the Learning Sciences: Sharing Good Practices of Research, Experimentation and Innovation (2005)

This paper proposes a three-dimensional Context-awareness (CA) model for e-learning that involves: Awareness to Knowledge Context, Awareness to Social Context and Awareness to Technical Context. The proposed CA is promising to support learning services providing in the e-learning context, such as knowledge navigation and collaboration recommendation. This paper also discusses a CA-supported learning services providing mechanism, which is mediated by the mining of the activity contexts of learners in e-learning environments.
Extracting, representing and mining semantic metadata from text: facilitating knowledge discovery in biomedicine
Authors: Amit Sheth
Venue:  (2008)

The information access paradigm offered by most contemporary text information systems is a search-and-sift paradigm where users have to manually glean and aggregate relevant information from the large number of documents that are typically returned in response to keyword queries. Expecting the users to glean and aggregate information has lead to several inadequacies in these information systems. Owing to the size of many text databases, search-and-sift is a very tedious often requiring repeated keyword searches refining or generalizing queries terms. A more serious limitation arises from the lack of automated mechanisms to aggregate content across different documents to discover new knowledge. This dissertation focuses on processing text to assign semantic interpretations to its content (extracting Semantic metadata) and the design of algorithms and heuristics to utilize the extracted semantic metadata to support knowledge discovery operations over text content. Contributions in extracting semantic metadata in this dissertation cover the extraction of compound entities and complex relationships connecting entities. Extraction results are represented using a standard Semantic Web representation language (RDF) and are manually evaluated for accuracy. Knowledge discovery algorithms presented herein operate on RDF data. To further improve access mechanisms to text content, applications supporting semantic browsing and semantic search of text are presented.
An Almost Totally Universal Tile Set
Authors: Grégory Lafitte, Michael Weiss
Venue: Proceedings of the 6th Annual Conference on Theory and Applications of Models of Computation (2009)

Wang tiles are unit size squares with colored edges. In this paper, we approach one aspect of the study of tilings computability: the quest for a universal tile set. Using a complex construction, based on Robinson's classical construction and its different modifications, we build a tile set μ (pronounced ayin) which almost always simulates any tile set. By way of Banach-Mazur games on tilings topological spaces, we prove that the set of μ-tilings which do not satisfy the universality condition is meager in the set of μ-tilings.

Authors: Radu-Viorel Ursianu, Emiliana Ursianu, Victor Ursianu
Venue: Proceedings of the 10th WSEAS international conference on Mathematical and computational methods in science and engineering (2008)

The aim of this paper is to describe the deterioration process of an electrical substation with multiple components. Some examples are given for power transformers and circuit breakers. The deterioration process is modeled by several distribution models like Weibull distribution. The reliability indicators and the bathtub curve are used to describe the electrical equipment.
Brief paper: Strong γk-γclH∞ stabilization with a new slack variable approach
Authors: Peng Cheng, Yong-Yan Cao, Youxian Sun
Venue: Automatica (Journal of IFAC) (2009)

This paper deals with the strong @c"k-@c"c"lH"~ stabilization problem. A new bounded real lemma is provided by adding two slack variables, which provides extra freedom to include more control constraints in handling robust control problems. With the extended bounded real lemma, a new sufficient condition is proposed for nth order strong @c"k-@c"c"lH"~ stabilization. It is also proved that the design of an lxnth order (l>=2) strong @c"k-@c"c"lH"~ controller can be transformed into that of an nth order controller for an associated plant, which tackles the possible order problem. Furthermore, the H"~ stable stabilization and strong stabilization problems can also be solved by relaxing certain constraints accordingly. Despite the BMI constraints, the path-following and alternative iteration methods are adopted to propose procedures for both nth and lxnth order controller designs. The effectiveness is indicated by several numerical examples.

Examining relational patterns of students' learning difficulties in statistical concepts using qualitative matrix and multidimensional scaling of interview data
Authors: Zamalia Mahmud, Rosli Abdul Rahim
Venue: Proceedings of the 2nd WSEAS international conference on Multivariate analysis and its application in science and engineering (2009)

Many researchers have recognized that the mixed mode method in the analysis of their research data to a great extent has provided them with a significant and informative result of their studies. However, the methodological techniques used are wide and it varies across different disciplines and areas of research. One area which is gaining popularity in research involving the use of both qualitative and quantitative data is in the research of statistical education. On that note, the main purpose of this paper is to describe the methodological techniques used in examining the relational patterns of students' learning difficulties in basic statistical concepts as perceived by the statistics educators. This paper shall discuss how patterns of interview conversations can be displayed using qualitative matrix and visualized using MDS two-dimensional solutions. The triangulation approach used have revealed findings which otherwise could not be elicited and interpreted through a single approach.
A Survey of Lower Bounds for Satisfiability and Related Problems
Authors: Dieter van Melkebeek
Venue:  (2007)

NP-completeness arguably forms the most pervasive concept from computer science as it captures the computational complexity of thousands of important problems from all branches of science and engineering. The P versus NP question asks whether these problems can be solved in polynomial time. A negative answer has been widely conjectured for a long time but, until recently, no concrete lower bounds were known on general models of computation. Satisfiability is the problem of deciding whether a given Boolean formula has at least one satisfying assignment. It is the first problem that was shown to be NP-complete, and is possibly the most commonly studied NP-complete problem, both for its theoretical properties and its applications in practice. A Survey of Lower Bounds for Satisfiability and Related Problems surveys the recently discovered lower bounds for the time and space complexity of satisfiability and closely related problems. It overviews the state-of-the-art results on general deterministic, randomized, and quantum models of computation, and presents the underlying arguments in a unified framework. A Survey of Lower Bounds for Satisfiability and Related Problems is an invaluable reference for professors and students doing research in complexity theory, or planning to do so.
Developing geosensor network support for Locawe platform: application of standards in low-rate communication context
Authors: Mika Luimula, Zach Shelby, Jouni Tervonen, Jouni Markkula, Petteri Weckström, Pertti Verronen
Venue: Proceedings of the 2009 international conference on Pervasive services (2009)

Wireless sensor and actuator networks (WSAN) are a combination of embedded, wireless and positioning technologies. Existing geospatial standards used in location-aware systems can be applied in building these networks, but they present challenges due to the characters of the geosensor networks. In this paper, we present a study of geospatial standards related to location-aware system platform for improving its interoperability. The location-aware system platform used here is Locawe. Locawe has been developed in CENTRIA and tested with wireless sensor and actuator network technologies in various industrial pilots including precision agriculture. This paper includes an experimental part, where we focus on geospatial standards in WSAN. In this field, geospatial standards are still under specification. Our first results show that geospatial standards can be applied also in WSAN, with certain limitations. These limitations are mainly related to low-rate data transmission and limited computing resources. We propose also further directions in standardization, which would be needed for geosensor networks and wireless applications for machines and systems.
Ubiquitous autonomic management: keynote abstract
Authors: Simon Dobson
Venue: Proceedings of the 6th international workshop on Managing ubiquitous communications and services (2009)

Network and systems management has in the past been rather inward-facing, in that management decisions have mainly been driven by factors within the network. Ubiquitous systems management must however be outward-facing towards the goals and constraints coming from outside the network. Autonomic systems, taken broadly, offer a rubric within which the model and address the trade-offs implied by this change of focus.
A Formal Approach for RDF/S Ontology Evolution
Authors: George Konstantinidis, Giorgos Flouris, Grigoris Antoniou, Vassilis Christophides
Venue: Proceeding of the 2008 conference on ECAI 2008: 18th European Conference on Artificial Intelligence (2008)

In this paper, we consider the problem of ontology evolution in the face of a change operation. We devise a general-purpose algorithm for determining the effects and side-effects of a requested elementary or complex change operation. Our work is inspired by belief revision principles (i.e., validity, success and minimal change) and allows us to handle any change operation in a provably rational and consistent manner. To the best of our knowledge, this is the first approach overcoming the limitations of existing solutions, which deal with each change operation on a per-case basis. Additionally, we rely on our general change handling algorithm to implement specialized versions of it, one per desired change operation, in order to compute the equivalent set of effects and side-effects. This work was partially supported by the EU projects CASPAR (FP6-2005-IST-033572) and KP-LAB (FP6-2004-IST-27490).
Incorporating lexical knowledge into biomedical NE recognition
Authors: Kyung-Mi Park, Seon-Ho Kim, Ki-Joong Lee, Do-Gil Lee, Hae-Chang Rim
Venue: Proceedings of the International Joint Workshop on Natural Language Processing in Biomedicine and its Applications (2004)

In this paper, we propose a two-phase biomedical named entity(NE) recognition method based on SVMs. We first recognize biomedical terms, and then assign appropriate semantic classes to the recognized terms. In the two-phase NE recognition method, the performance of term recognition is critical to the overall performance of the system because term recognition errors can be propagated to the semantic classification phase. In this study, we try to improve the performance of term recognition by using lexical knowledge. We utilize salient NPs and collocations as lexical knowledge extracted from raw corpus. In addition, we use morphological knowledge extracted from training data as features for learning SVM classifiers. Experimental results show that our system obtains an F-measure of 62.97% on the test data, and that the performance can be improved upto 2.82% by using lexical knowledge.
Computers in the Human Interaction Loop, 1st edition
Authors: Alexander Waibel, Rainer Stiefelhagen
Venue:  (2009)

This book integrates a wide range of research topics related to and necessary for the development of proactive, smart, computers in the human interaction loop, including the development of audio-visual perceptual components for such environments; the design, implementation and analysis of novel proactive perceptive services supporting humans; the development of software architectures, ontologies and tools necessary for building such environments and services, as well as approaches for the evaluation of such technologies and services. The book is based on a major European Integrated Project, CHLI (Computers in the Human Interaction Loop), and throws light on the paradigm shift in the area of HCI that rather than humans interactive directly with machines, computers should observe and understand human interaction, and support humans during their work and interaction in an implicit and proactive manner.

Reducing temporal delays in a real time train management system
Authors: Per Kreuger, Malin Forsgren, Martin Aronsson
Venue: Proceeding of the 2008 conference on Tenth Scandinavian Conference on Artificial Intelligence: SCAI 2008 (2008)

We report results on a combined scheduling and resource allocation problem in transportation. The problem occurs in a real time management system for vehicles when it is disturbed by introducing unplanned service tasks and temporal delays of the transportation and service tasks. A method to solve the the problem using a constraint programming model is described in some detail. Preliminary test runs of the solver on problem sets generated by a simulator taking statistic models of the wear of the vehicle components into account are also reported.
Optimal control by energetic criterion of driving systems
Authors: Niculau Boteanu, Marius-Constantin Popescu, Florin Ravigan
Venue: Proceedings of the 10th WSEAS international conference on Mathematical and computational methods in science and engineering (2008)

In the paper we consider an electric drive having static load torque with a constant component, a speed proportional component and a proportional with the square of speed, in the hypothesis of constant inertia moment and of proportionality between the electromagnetic torque and the load current. Using variational calculus, optimally condition and expression of optimal control and extremal trajectory are determined, which ensures the minimum of energy losses caused by the load current through a Joule effect in the acceleration processes. Using numerical computer we can obtain graphical representation of these variables as time functions.
