The document indexing is a fairly sensitive phase in the information retrieval. However, terms presented in a document are not sufficient to completely represent it. Then, the exploitation of the implicit information, through external resources, is necessary for better indexing. For this purpose, a new indexing model for biomedical documents based on description logics has been proposed to generate...
In the present the feasibility of a concept for development of a virtual reality laboratory in electrical circuits is verified. The concept aims to create an engine, which would allow to implement custom virtual equipment, whose behavior and GUI is loaded from a database and implemented dynamically. The implementation is based on variables, which are manipulated and visualized by the different equipment...
The article discusses the concept of a balanced solution of economic tasks and problems of preservation of the environment, research of problems of environmental management, the analysis of existing approaches to environmental-economic environmental management, methodological bases of perfection of system of nature management on the basis of improving environmental and economic security management...
The Information and Communication Technology (ICT) has generated important changes in the education process. This paper presents an overview of u- learning as a paradigm that enriches the teaching and learning process at anytime, anywhere, and with any device. It proposes a new concept, characteristics, uses and application scenarios, and possible topics for research, looking for more reflection and...
Massive data applications such as E-science applications are characterized by complex treatments on large amounts of data which need to be stored in distributed data centers. In fact, when one task needs several datasets from different data centers, moving these data may cost a lot of time and cause energy's high consumption. Moreover, when the number of the data centers involved in the execution...
The paper proposes a concept to unify the tools used by software developers. The goal of the paper is to describe a conceptual framework, based on client-server architecture, which aims to simplify the introduction to new development tools for new users. The framework also tries to solve the issue with multiple tools serving the same purpose as well as making the process of switching between these...
Ontology learning is a field of extracting ontological elements to form ontology. Identification of concepts is the main activities within ontology learning. Diverse methods can be used to find concepts. One of the methods is using collocation learning technique. The technique used statistical scores which to test the strength of the connection between terms. In English translated Quran, single term...
An ontology is a formal and explicit specification of a shared conceptualization. Manual construction of domain ontology does not adequately satisfy requirements of new applications, because they need a more dynamic ontology and the possibility to manage a considerable quantity of concepts that humans cannot achieve alone. Researchers have discussed ontology learning as a solution to overcome issues...
We describe a system for ocean observatories which streams data from the seafloor to shore in near real-time without a cable or moored surface buoy. The system utilizes a Wave Glider® (Liquid Robotics, Inc.); an autonomous surfboard-sized maritime vehicle that harvests wave energy for propulsion and solar energy for electrical power. The Wave Glider acts as a communications gateway as it hovers on...
These days IT service providers are rapidly embracing an automated services delivery model in order to keep pace with advances in technology and demanding market pressure to reduce and maintain quality. Application development and maintenance is a good example of a service system in which a sizable volume of tickets are raised everyday for different issues to get resolved with a view to deliver uninterrupted...
The evolution of the harmonized set of ISO/IEC/IEEE 15288-12207 related standards and technical reports that are discussed in this International Standardprovides detailed requirements and guidance on the application of system life cycle processes. This International Standard unifies technical and managementrequirements and guidance from several of these sources to specify the requirements for the...
Lot of time is spent on E-Mails for communication in today's IT world, peoples prefer to send email for business purpose and information exchange. Email management is necessary because once our inbox is full of mails we avoid to read out one by one in that case some important email may get missed. Always user try to avoid unnecessary email reading for that a better email management system is required...
The problem of recognition of handwritten characters is still an active area of research which accord more attention. In this context, our paper focuses on purpose of a new approach based on the integration of reasoning logic using OWL ontology and SWRL rules to the classification phase. Our ontology consists of a set of concepts and spatial relations between them, the main concept is the Arabic character...
The classification of unmanned aerial vehicles is considered. The main disadvantages of modern unmanned aerial vehicles systems are determined. The demands for unmanned aerial vehicles systems are presented.
The paper discusses the possibility of generation of a set of reusable educational components by means of paradigms of knowledge representation and management, based on contemporary concepts and tools in educational and informational technologies. Definitions of knowledge models such as ontology and characteristics of conception; model of knowledge specification and knowledge expressions by means...
The process of learning can be improved with proper and timely feedback. This paper proposes a system that provides feedback for both teacher and student using concept-based learning. Various types of concepts are defined, and assessment is done for each concept. The level of knowledge acquired by students can be clearly represented using this approach. The feedback provided is goal-oriented, active,...
Feature model is an important model of capturing domain requirements. The traditional feature modeling methods extract the characteristics from the extension of the system. However, the methods fail to describe feature in details especially for embedded software product line engineering. As for these deficiencies, this paper combines the characteristics of the embedded products, with the domain ontology...
Word similarity computation has important applications in many areas, such as natural language processing, intelligence information retrieval, document clustering, automatic answering, word sense disambiguation, machine translation etc. This article makes an intensive study of word similarity computation based on HowNet and the word similarity is computed in three steps: (1) computes sememes similarity,...
In the present article is given the conception of vector multi-component physical value, are shown the measurement problems of informative components of multi-component displacements by optical method. Also are presented the Fundamentals of the named optical measurement values on the basis of the multidimensional test objects method.
The goal of the article is to inform professionals about possibilities of both active and passive participation in the Leonadro da Vinci Project called “Flexible learning in European retail”. This project is a free continuation of a project held in the years 2007–2009, which stressed the importance of corporate social responsibility and environmental approach of businesses. The follow-up project addresses...
