Domēnspecifisku rīku konfigurācijas valoda un tās realizācija
2014
Promocijas darbā ir izstrādāts konfigurators plaša profila DSML rīku definēšanai. Konfigurators balstās uz ideju, ka DSML definīciju var uzdot ar universālu metamodeli (UML klašu diagrammas formā), kura pēc tam konfiguratorā tiek apstrādāta, lai nodrošinātu rīka darbību. Turklāt nestandarta gadījumiem, kad esošās metamodeļa iespējas ir nepietiekošas, metamodelī ir realizēts paplašinājuma punktu mehānisms, kas ļauj pievienot rīkam specifiski transformāciju valodā noprogrammētu funkcionalitāti. Izstrādātais konfigurators ir pārbaudīts vairākos praktiskos lietojumos un apliecinājis savu efektivitāti.
Framework for Evaluating the Version Management Capabilities of a Class of UML Modeling Tools from the Viewpoint of Multi-Site, Multi-Partner Product…
2010
UML models are widely used in software product line engineering for activities such as modeling the software product line reference architecture, detailed design, and automation of software code generation and testing. But in high-tech companies, modeling activities are typically distributed across multiple sites and involve multiple partners in different countries, thus complicating model management. Today's UML modeling tools support sophisticated version management for managing parallel and distributed modeling. However, the literature does not provide a comprehensive set of industrial-level criteria to evaluate the version management capabilities of UML tools. This article's contributio…
Teaching Programming to Large Student Groups through Test Driven Development - Comparing Established Methods with Teaching based on Test Driven Devel…
2016
This paper presents an approach for teaching programming in large university classes based on test driven development (TDD) methods. The approach aims at giving the students an industry-like environment already in their education and introduces full automation and feedback programming classes through unit testing. The focus for this paper is to compare the novel approach with existing teaching methods. It does so by comparing introduction to programming classes in two institutions. One university ran a TDD teaching process with fully automated assessments and feedback, while the other ran a more traditional on-line environment with manual assessments and feedback. The TDD approach has clear…
Editorial: Interrogating the design of smart, sustainable, and socially just urban spaces: A look at institutions, places, and values
2022
The article is the Editorial on the Research Topic Interrogating the design of smart, sustainable, and socially just urban spaces: A look at institutions, places, and values, which explore the dynamics between the socio-technological processes – value-based design being foremost among them – through which urban space emerges and takes on meaning. Furthermore, they engage with the question of how institutional design principles shape citizen participation in these processes.
Data-Driven Adaptive Observer for Fault Diagnosis
2012
Published version of an article from the journal: Mathematical Problems in Engineering. Also available from the publisher:http://dx.doi.org/10.1155/2012/832836 This paper presents an approach for data-driven design of fault diagnosis system. The proposed fault diagnosis scheme consists of an adaptive residual generator and a bank of isolation observers, whose parameters are directly identified from the process data without identification of complete process model. To deal with normal variations in the process, the parameters of residual generator are online updated by standard adaptive technique to achieve reliable fault detection performance. After a fault is successfully detected, the iso…
Organizāciju cilvēkresursu analītikas attīstības līmenis Eiropā
2018
Cilvēkresursu analītika, kas operē ar datiem lēmumu pieņemšanas procesos, visā pasaulē kļuva par aktuālu tematu. Bakalaura darba mērķis ir izpētīt Eiropas cilvēkresursu analītikas attīstības līmeni un sniegt ieteikumus organizācijām, cilvēkresursu speciālistiem un akadēmiskām iestādēm, lai veiksmīgi ievest cilvēkresursu analītiku. Pētījuma pamatā ir kvalitatīvi dati, kuri tika iegūti intervējot četrus cilvēkresursu speciālistus. Secināts, ka ir būtiska vajadzība pēc cilvēkresursu analītikas un intervētiem organizāciju pārstāvjiem šī tēma ir pazīstama. Galvenais izaicinājums ir saistīts ar profesionālo prasmju trūkumu, tomēr nākotnei cilvēkresursu analītikas cerības ir pozitīvas.
ISTehnology - Metamodel based approach to information system development
2014
Document describes experience of using metamodel-based tool ISTehnology in development of information systems. The author of this document is one of the developers of ISTehnology. The main goal of the research is to figure out the framework (methodology and tools) for building information systems able to work in variable business environment and easy changeable. ISTechnology is such a framework. The document describes a metamodel of ISTehnology, approach to information systems development, advantages and disadvantages of its usage and possibilities to prevent disadvantages by using modern graphical tools of modeling.
Constructing Knowledge through a Role-Play in a Web-Based Learning Environment
2003
This study aimed to find out how and on what level the students of two separate secondary schools shared and constructed knowledge on imperialism by interacting through historical role characters in a Web-based environment. Furthermore, the study aimed to find out how social and contextual features affected the nature of knowledge sharing and construction. The data about the history project were gathered by various means in order to validate the findings of the case study. The results demonstrated that the level of the Web-based messages remained quite low. Also the use of the Web-based environment in terms of shared knowledge construction was rather weak. In comparison, different instruct…
An atlas- and data-driven approach to initializing reaction-diffusion systems in computer cardiac electrophysiology
2016
The cardiac electrophysiology (EP) problem is governed by a nonlinear anisotropic reaction-diffusion system with a very rapidly varying reaction term associated with the transmembrane cell current. The nonlinearity associated with the cell models requires a stabilization process before any simulation is performed. More importantly, when used in a 3-dimensional (3D) anatomy, it is not sufficient to perform this stabilization on the basis of isolated cells only, since the coupling of the different cells through the tissue greatly modulates the dynamics of the system. Therefore, stabilization of the system must be performed on the entire 3D model. This work develops a novel procedure for the i…
TOWARDS SEMANTIC INTEROPERABILITY FOR ENTERPRISE INFORMATION SYSTEMS
2016
International audience; In the context of globalisation, data and knowledge management, and given the need to deliver a quick response to changes in market forces, enterprises have to collaborate using information technologies to succeed in a disparate and dynamical business environment. Enterprise interoperability (EI) is a field of study that aims to improve this collaboration. Moreover, EI addresses problems related to the lack of system interoperability in organisations. In this paper, we focus on approaches which deliver semantic interoperability among enterprise information systems. We conclude by identifying the main drawbacks of such approaches to be adopted by world-wide industry a…
