XCDL: an XML-oriented visual composition definition language

2010

International audience; XML data flow has reached beyond the world of computer science and has spread to other areas such as data communication, e-commerce and instant messaging. Therefore, manipulating this data by non expert programmers is becoming imperative. On one hand, Mashups have emerged a few years ago, providing users with visual tools for web data manipulation but not necessarily XML specific. Mashups have been leaning towards functional composition but no formal languages have yet been defined. On the other hand, visual languages for XML have been emerging since the standardization of XML, and mostly relying on querying XML data for extraction or structure transformations. These…

Programming languages for data-Intensive HPC applications: A systematic mapping study

2020

This work is a result of activities from COST Action 10406 High -Performance Modelling and Simulation for Big Data Applications (cHiPSet), funded by the European Cooperation in Science and Technology. FCT, Portugal for grants: NOVA LINCS Research Laboratory Ref. UID/ CEC/ 04516/ 2019); INESC-ID Ref. UID/CEC/50021/2019; BioISI Ref. UID/MULTI/04046/2103; LASIGE Research Unit Ref. UID/CEC/00408/ 2019. A major challenge in modelling and simulation is the need to combine expertise in both software technologies and a given scientific domain. When High-Performance Computing (HPC) is required to solve a scientific problem, software development becomes a problematic issue. Considering the complexity…

Automated source code transformations on fourth generation languages

2004

To control the operation of large application suites or to tailor a special purpose application to particular need, developers frequently use application specific languages, such as batch, scripting, and query languages. These languages which are also referred to as fourth generation languages (4GLs) therefore play an important role in today's economy. Incompatibilities between different versions of 4GLs and changing requirements may make massive changes on a company's library of 4GL programs necessary. Here, we explore possibilities for performing mass changes on 4GLs and show how the transformation of programs written in 4GLs compares to the transformation of mainstream programming langua…

Metamodel specialization for graphical modeling language support

2016

Most of current modeling languages are based on graphical diagrams. The concrete graphical syntax of these languages typically is defined informally -- by text and diagram examples. Only recently, starting from UML 2.5, a formalism is offered for defining the graphical syntax of UML. This formalism is based on Diagram Definition standard by OMG, where the main emphasis is on enabling diagram interchange between different tools implementing the given language. While this is crucial for standardized languages such as UML, this aspect is not so important for domain specific languages. In this paper an approach is offered for simple direct definition of concrete graphical syntax by means of met…

Tree Based Domain-Specific Mapping Languages

2012

Model transformation languages have been mainly used by researchers --- the software engineering industry has not yet widely accepted the model driven software development (MDSD). One of the main reasons is the complexity of metamodelling principles the developers are required to know to actually use model transformations in the way the OMG has stated. We offer the basic principles how to create domain-specific model transformation languages which can be used by developers relying only on familiar modelling concepts. We propose to use simple graphical mappings to specify the correspondence between source and target models which are represented using trees based on the concrete syntax of und…

Trading off accuracy for efficiency by randomized greedy warping

2016

Dynamic Time Warping (DTW) is a widely used distance measure for time series data mining. Its quadratic complexity requires the application of various techniques (e.g. warping constraints, lower-bounds) for deployment in real-time scenarios. In this paper we propose a randomized greedy warping algorithm for finding similarity between time series instances. We show that the proposed algorithm outperforms the simple greedy approach and also provides very good time series similarity approximation consistently, as compared to DTW. We show that the Randomized Time Warping (RTW) can be used in place of DTW as a fast similarity approximation technique by trading some classification accuracy for ve…

Valoda: nozīme un forma. Plašsaziņas līdzekļu valoda

2009

Šajā krājumā apkopotās publikācijas veidotas uz referātu pamata, kas nolasīti Latvijas Universitātes Filoloģijas un mākslas zinātņu fakultātē notikušajos semināros “Funkcionālie stili un runas žanri plašsaziņas līdzekļos” 2007. un 2008. gadā. Krājumā ietverti gan zinātniski, gan populārzinātniski raksti, kas adresēti plašam interesentu lokam. Sākumā aplūkoti vispārīgi jautājumi par publicistikas valodas vietu latviešu valodas funkcionālo paveidu sistēmā, pēc tam analizētas leksikas lietojuma īpatnības un daži plašsaziņas līdzekļu valodas gramatiskie aspekti, krājuma beigu daļā vairāki reklāmas un sludinājumu valodai veltīti raksti, kā arī pētījumi par lietišķā stila izmantojumu plašsaziņas …

LET'S PLAY INTO THE ENGLISH CLASSROOM.

2015

The role of playing as an extremely effective teaching tool with learners at every age has been already well acknowledged by authors from all over the world. In the FL classroom the fundamental characteristic of the gaming approach is the turn over of the perspective that not only emphasizes the affective relationship that occurs between teacher and student in the teaching/learning process, but also underlines the centrality of the learner as the main actor in the learning process. Games in the classroom help create communicative and significant learning environments where attention to individuals or to special education needs, respect of the rules, cooperation, solidarity, overcoming of di…
