Interoperability between Distributed Systems and Web-Services Composition
2009
An information system is a multi-axis system characterized by a “data” axis, a “behavioral” axis, and a “communication” axis. The data axis corresponds to the structural and schematic technologies used to store data into the system. The behavioral axis represents management and production processes carried out by the system and corresponding technologies. The processes can interact with the data to extract, generate, and store data. The communication axis relates to the network used to exchange data and activate processes between geographically distant users or machines. Nowadays, technologies required for interoperability are extended to deal with the semantic aspect of the information sys…
A Semantic Publish/Subscribe Approach for U-VR Systems Interoperation
2008
As ubiquitous virtual reality (U-VR) systems become more and more popular and several systems coexist all together, sharing events between them in order to improve the user experience and increase their scope and functionality will be mandatory. Since U-VR systems have a dynamic and decoupled nature, and they have their own event model, we propose in this paper a semantic publish/subscribe infrastructure that lies on a description logics reasoner and OWL ontologies for managing heterogeneous event models and performing the matching of events and subscriptions in such U-VR systems.
The Web Computer and Its Operating System: A New Approach for Creating Web Applications
2019
Web applications require not only more sophisticated infrastructure than traditional single-PC applications, but also a different way of thinking, where network-specific aspects have to be considered. In this paper, we introduce the web computer concept, which factors out network-related issues and provides an illusion of a single computer with directly attached CPUs, memory, and I/O devices. By assuming the web computer and its open operating system (webAppOS) as a target platform for web applications, developers can preserve the same level of thinking as when developing classical desktop applications. With this approach, which corresponds to the physiology of the human brain, web applicat…
EVALUATION OF THE EFFECTS OF CONTI- NUOUS PREPERITONEAL WOUND INFILTRATION ON POSTOPERATIVE RESPIRATORY PERFORMANCE IN PATIENTS WHO UNDERWENT MAJOR A…
2013
Aim. According to the recent literature, continuous pre-perito- neal wound infiltration with local anaesthetics (CPWI) is an effective analgesic therapy in patients who undergo major abdominal surgery 1. Although it is not inferior to other com- monly used techniques in postoperative analgesia, many studies report conflictive results about its efficacy compared to them 2. The aim of our study was to evaluate the effects of CPWI on the postoperative respiratory performance in patients after major abdominal surgery. Materials and methods. From June 2011 to July 2012, a total of 14 patients have been evaluated. All patients were treated using the protocol generally used in our Department for t…

Magnetic exchange interaction in clusters of orbitally degenerate ions. II. Application of the irreducible tensor operator technique
2001
Abstract The irreducible tensor operator technique in R3 group is applied to the problem of kinetic exchange between transition metal ions possessing orbitally degenerate ground states in the local octahedral surrounding. Along with the effective exchange Hamiltonian, the related interactions (low-symmetry crystal field terms, Coulomb interaction between unfilled electronic shells, spin–orbit coupling and Zeeman interaction) are also taken into account within a unified computational scheme. Extension of this approach to high-nuclearity systems consisting of transition metal ions in the orbital triplet ground states is also demonstrated. As illustrative examples, the corner-shared D4h dimers…
Lāčplēša tēma latviešu apziņā, literatūrā, mākslā un LU mācībspēku pētījumos
2022
Atzīmējot Andreja Pumpura eposa “Lāčplēsis” 135. gadadienu, kas aprit 2023. gada jūnijā, Humanitāro zinātņu bibliotēkā tika izveidota izstāde "Lāčplēša tēma latviešu apziņā, literatūrā, mākslā un LU mācībspēku pētījumos". Eposs tika publicēts 1888. gada jūnijā saistībā ar Trešo Vispārējo latviešu dziesmu svētku norisēm. Darbs tapis, sintezējot teikas, pasakas un laikabiedru priekšstatus par senatni, saskaņā ar 19. gs. nacionālā romantisma idejām Eiropā laikā, kad eposa esamība tika uztverta kā nācijas eksistences apliecinājums. Izstāde izkārtota 4 plauktos. Pirmajā plauktā izstādīts eposa 1888.gada izdevums. Otrajā plauktā redzami Latvijas Universitātes mācībspēku pētījumi, skatot Lāčplēsi …

Interpreting Heterogeneous Geospatial Data Using Semantic Web Technologies
2016
International audience; The paper presents work on implementation of semantic technologies within a geospatial environment to provide a common base for further semantic interpretation. The work adds on the current works in similar areas where priorities are more on spatial data integration. We assert that having a common unified semantic view on heterogeneous datasets provides a dimension that allows us to extend beyond conventional concepts of searchability, reusability, composability and interoperability of digital geospatial data. It provides contextual understanding on geodata that will enhance effective interpretations through possible reasoning capabilities. We highlight this through …
