Tieteelliset laskentasovellukset ja pilvipalvelut – erityistarkastelussa AWS
2014
Perinteisesti IT-resurssien hankinta on tapahtunut hankkimalla laitteistoa ja ohjelmistoja omaan tai organisaation omistukseen. Näiden resurssien käyttö on yleensä tarkoittanut merkittäviä investointeja laitteistoihin, ohjelmistoihin ja näiden ylläpitoon. Suuressa organisaatiossa kalliiden IT-resurssien käyttöönotto voi olla joissain tapauksissa hyvinkin byrokraattinen prosessi. Tieteellinen laskenta edellyttää usein erittäin suurta laskenta- ja tallennuskapasiteettia. Tutkijat hyötyisivät raskaaseen laskentaan vaadittavien IT-resurssien hankkimisesta palveluna, jolloin usein niukat resurssit voitaisiin keskittää vaadittavan laitteiston hankkimisen ja ylläpidon sijaan ydinongelman tutkimise…
A VIRTUAL HUB BROKERING APPROACH FOR INTEGRATION OF HISTORICAL AND MODERN MAPS
2016
Geospatial data are today more and more widespread. Many different institutions, such as Geographical Institutes, Public Administrations, collaborative communities (e.g., OSM) and web companies, make available nowadays a large number of maps. Besides this cartography, projects of digitizing, georeferencing and web publication of historical maps have increasingly spread in the recent years. In spite of these variety and availability of data, information overload makes difficult their discovery and management: without knowing the specific repository where the data are stored, it is difficult to find the information required and problems of interconnection between different data sources and th…
Smart Monitoring for Semantic Wireless (SCADA/DCS) Systems with Semantic SNMP Protocol.
2015
International audience; n this paper we propose a new implementation of SNMP protocol through (WS) and SOAP protocol, for wireless semantic (SCADA/DCS) systems and (IT-SCADA) platform monitoring. (WS) and SOAP may run on top of secure transport services implemented through protocols like HTTPS combined with industrial protocols as (DNP3, SOAP, ISM BAND, and ZIGBEE).We chose ZIGBBE wireless protocol for implementing our semantic security (IT-SCADA) management platform with semantic SNMP protocol via WS. To detect and infiltrate wireless radio network and semantic attacks, the use of (WS) gateways is needed to include SNMP devices into (WS) based management architecture. The evaluation shows …
Semantic Web Services for Smart Devices in a “Global Understanding Environment”
2003
Various Web resources and services are usually assumed to be used and accessed by human users (current Web) or by software agents on behalf of human users (emerging Semantic Web). However industry emerges also a new group of “users”, which are smart industrial devices, robots or any other objects, which can be adapted to the (Semantic) Web environment. They would need special services for e.g. online condition monitoring, information provisioning, remote diagnostics, maintenance support, etc. The goal of this paper is to specify main requirements to Web services that automatically follow up and predict the performance and maintenance needs of field devices. Semantic Web enabled services for…

Semantic Web Services for Smart Devices Based on Mobile Agents
2005
Among traditional users of Web resources, industry has a growing set of smart industrial devices with embedded intelligence. Just like humans, they need online services (i.e., for condition monitoring, remote diagnostics, maintenance, etc.). In this paper, we present one possible implementation framework for such Web services. Such services should be Semantic Web enabled and form a Service Network based on internal and external agents’ platforms, which can host heterogeneous mobile agents and coordinate them to perform needed tasks. The concept of a “mobile service component†assumes not only exchanging queries and service responses, but also delivering and composition of a service pro…
Mantotas sistēmas automatizēta izvietošana Amazon tīmekļa servisu mākonī
2017
Kvalifikācijas darba ietvaros mantotai sistēmai tika izveidota infrastruktūra kā kods izmantojot Terraform, kā arī automatizācijas skripti ar kuru palīdzību ir iespējams automatizēti izvietot Amazon tīmekļa servisu mākonī mantoto sistēmu. Šī darba mērķi ir: ● ļaut uzstādīt programmatūru uz mākonī automatizēti ar minimālu piepūli. ● pārvietot esošo sistēmu, mākonī, lai izslēgtu nepieciešamību pēc tās fiziskas uzturēšanas. ● atvieglot izstrādātājiem papildināt mantotās sistēmas funkcionalitāti. ● modificēt mantoto sistēmu, lai tā izmanto jaunāku programmatūru salīdzinot ar tagadējo sistēmu. Izstrādātie rīki nodrošina automātizētu procesu infrastruktūras izveidošanai, kā arī automātizētu progr…
SIMILARITY NETWORK FOR SEMANTIC WEB SERVICES SUBSTITUTION
2013
Web services substitution is one of the most challenging tasks for automating the composition process of multiple Web services. It aims to improve performances and to deal efficiently with Web services failures. Many existing solutions have approached the problem through classification of substitutable Web services. To go a step further, we propose in this paper a network based approach where nodes are Web services operations and links join similar operations. Four similarity measures based on the comparison of input and output parameters values of Web services operations are presented. A comparative evaluation of the topological structure of the corresponding networks is performed on a ben…
ECONOMICAL SYSTEMS - NEW TRENDS FOR APPLICATION INTEROPERABILITY
2012
Web Services and Service Oriented Architecture (SOA) registered an important increase in the past years. The aim of the Paper is to analyse the manner in which these technologies are used by the local business and how they can lead to the improvement of processes within enterprises. The paper includes the results of a study dedicated to determine the level of usage of these technologies in Romanian companies.
Web Services Specific Security Standards
2014
Abstract In this paper are described the aspects regarding the security within OGSA framework, introducing WS-Security standard – OASIS standard for Web Services security. There are approached the security aspects of the OGSA environment for the delivered architectures P2P – ‘Peer-to-Peer’ and there are presented the recent initiatives for creating a specific and adapted environment OGSA for the applications P2P and the specific security demands of these transactions. Furthermore, there are exposed aspects regarding the mobility of services and resources in the P2P context, with the conditions of applying WSRF framework, derived from OGSA to the P2P environments, SOA processes in P2P enviro…
