Tags pose an efficient and effective way of organization of resources, but they are not always available. A technique called SCM/THD investigated in this paper extracts entities from free-text annotations, and using the Lin similarity measure over the WordNet thesaurus classifies them into a controlled vocabulary of tags. Hypernyms extracted from Wikipedia are used to map uncommon entities to Wordnet synsets. In collaborative environments, users can assign multiple annotations to the same object hence increasing the amount of information available. Assuming that the semantics of the annotations overlap, this redundancy can be exploited to generate higher quality tags. A preliminary experiment presented in the paper evaluates the consistency and quality of tags generated from multiple annotations of the same image. The results obtained on an experimental dataset comprising of 62 annotations from four annotators show that the accuracy of a simple majority vote surpasses the average accuracy obtained through assessing the annotations individually by 18%. A moderate-strength correlation has been found between the quality of generated tags and the consistency of annotations.

This paper considers problem of stabilization of the first order nonholonomic chained system using polar-like coordinates. A control method considered here can be regarded as an extension of control solution based on polar coordinate transformation in order to apply it to other system than unicycle. Presented control strategy gives possibility to obtain fast convergence of regulation errors without oscillatory behavior. A robustness of the controller in the neighborhood of the desired point is ensured via additional non-smooth techniques. In order to verify usefulness of developed control strategy simulation results are given.

Virtual systems for definition, analysis and application of product models are widely applied in development, production, and application of products. These systems provide outstanding performance in description of product information. At the same time, any modification of earlier decided product information needs contribution from the original decision maker. Otherwise new decision is to be made while the original intent is not available. The authors conceptualized a new modeling method where human intent is stored in the product model as content of modeled information. This content is applied at new decision making. Some aspect of this new modeling is introduced in this paper starting with an introduction to model based product development. Following this, a method is shown for tracking affected engineering object chains by using of change affect zone (CAZ) definition. Next, the authors propose an information content extension to product model. They studied current information based product models, recognized conflict as caused by application of information based product modeling, and decided to complete the information based product model by information content based model. The conflict is in the communication between information based modeling procedures and information content based human. The proposed modeling can be implemented as an extension to functionality and model of professional product lifecycle management (PLM) systems.

The systematic conception of decentralized and self-adaptive software systems, as demanded for the run-time management of today’s distributed, multi-tier software architectures, is an active research area. Here, we discuss a coordination architecture that facilitates the enactment of externalized coordination models in Multi-agent Systems (MAS). Coordination is configured by systemic models, i.e. structures of agent-behaviour interdependencies that denote the mutual influences of agent activities. The systematic, iterative application development is supported by a non-intrusive integration approach that enables developers to adjust application dynamics by complementing agent-based applications with systemic coordination models.

The paper presents a new systematic analysis method in order to estimate the total absorbed power and energy in linear electric and magnetic circuits with modifiable parameters. The relation between the variation in one or all the resistances and reluctances of the networks and the variation of total absorbed power and energy are discussed using the Lagrange's method. For the considered applications the results are obtained with Mathematica and Maple useful for establishing the variation limits of absorbed power and energy.

This paper is concerned with a strictly positive real H 2 controller design problem using an observer-based controller with Kalman filter gain. In this paper, we propose a successive method with non-common Lyapunov variables for this control problem. The feature of our method is to construct a controller sequence on which H 2 norm is monotonically non-increasingly while all controllers are strictly positive real. A numerical example shows the efficiency of our method.

Robustness analysis and visualization are two of key concepts of multi-criteria decision support. They enable the decision-maker to improve his understanding of both the model and the problem domain. A class of original mathematical optimization based robustness metrics is hence defined in this paper. In addition, several efficient existing techniques that have been successfully used in various ICT projects are presented. They include the stability intervals/regions and the principal components analysis. All approaches are applied to the multi-attribute utility function, and to the PROMETHEE II and ELECTRE TRI methods. Their benefits are discussed and demonstrated on real life cases.

Performance evaluation is a serious challenge in designing or optimizing reconfigurable instruction set processors. The conventional approaches based on synthesis and simulations are very time consuming and need a considerable design effort. A combined analytical and simulation-based model (CAnSO*) is proposed and validated for performance evaluation of a typical reconfigurable instruction set processor. The proposed model consists of an analytical core that incorporates statistics gathered from cycle-accurate simulation to make a reasonable evaluation and provide a valuable insight. Compared to cycle-accurate simulation results, CAnSO proves almost 2% variation in the speedup measurement.

This paper explains our developing Corpus of Japanese classroom Lecture speech Contents (henceforth, denoted as CJLC). Increasing e-Learning contents demand a sophisticated interactive browsing system for themselves, however, existing tools do not satisfy such a requirement. Many researches including large vocabulary continuous speech recognition and extraction of important sentences against lecture contents are necessary in order to realize the above system. CJLC is designed as their fundamental basis, and consists of speech, transcriptions, and slides that were collected in real university classroom lectures.
