Architecture and Language for Semantic Reduction of Domain-Specific Models in BPMS
2012
Nowadays each business process management system (BPMS) supports either an industry standard or its own specific modeling language. But no BPMS supports a specific language for each organization. We propose an architecture for building BPMS that allows creating a domain-specific modeling language for every client easily. The main problem is to bridge the gap between the domain-specific language and the executable language. We show that we can look at this problem as a classification of the domain-specific language constructs in the terms of the executable language. To solve this problem we present a novel model transformation language, with which this type of problem can be solved more natu…
Adapting hierarchical bidirectional inter prediction on a GPU-based platform for 2D and 3D H.264 video coding
2013
The H.264/AVC video coding standard introduces some improved tools in order to increase compression efficiency. Moreover, the multi-view extension of H.264/AVC, called H.264/MVC, adopts many of them. Among the new features, variable block-size motion estimation is one which contributes to high coding efficiency. Furthermore, it defines a different prediction structure that includes hierarchical bidirectional pictures, outperforming traditional Group of Pictures patterns in both scenarios: single-view and multi-view. However, these video coding techniques have high computational complexity. Several techniques have been proposed in the literature over the last few years which are aimed at acc…
Three-dimensional Fuzzy Kernel Regression framework for registration of medical volume data
2013
Abstract In this work a general framework for non-rigid 3D medical image registration is presented. It relies on two pattern recognition techniques: kernel regression and fuzzy c-means clustering. The paper provides theoretic explanation, details the framework, and illustrates its application to implement three registration algorithms for CT/MR volumes as well as single 2D slices. The first two algorithms are landmark-based approaches, while the third one is an area-based technique. The last approach is based on iterative hierarchical volume subdivision, and maximization of mutual information. Moreover, a high performance Nvidia CUDA based implementation of the algorithm is presented. The f…

A Formal Semantics and a Client Synthesis for a BPEL Service
2008
A complex Web service described with languages like BPEL4WS, consists of an executable process and its observable behaviour (called an abstract process) based on the messages exchanged with the client. The abstract process behaviour is non deterministic due to the internal choices during the service execution. Furthermore the specification often includes timing constraints which must be taken into account by the client. Thus given a service specification, we identify the synthesis of a client as a key issue for the development of Web services. To this end, we propose an approach based on (dense) timed automata to first describe the observable service behaviour and then to build correct inte…
Determinants to the Use of Business Process Modeling
2010
This article addresses a theoretical gap in the BPM literature on factors that influence the acceptance of process modeling (PM) in organizations. Literature review on PM and 34 qualitative interviews were combined into a PM acceptance model and empirically tested with data from 74 companies showing that PM is to a large extent a mandated activity, explaining the missing link between PM attitudes on PM intention. The study extends the TAM and the TPB to the context of process modeling and demonstrates that less studied socio-political factors in addition to awareness of PM are important to understand PM acceptance. The findings show that social influence from different stakeholder reference…
Unified computing facility design based on open source software
2012
The article describes e-infrastructure development in Latvia and migration to national Cloud as regional partner facility (RPF) in European Union (EU). In Latvia many public and private Computing Clouds is in operation and problem is how to integrate these resources as one RPF and how to design one unified computing facility that is used for many different applications. The authors offer their solution at Cloud software as a Service and Hardware as a Service level which is based on usage of open source packaged bundles.
Oracle Intelligent Bots Cloud Service piedāvātās iespējas
2018
Bakalaura darba “Oracle Intelligent Bots cloud service piedāvātās iespējas” mērķis ir izpētīt, kas ir virtuālais asistents, kāds ir tā izstrādes process un noskaidrot, kādas ir cilvēku zināšanas par šāda veida programmatūru. Pētījumā tiek izstrādāts Oracle virtuālais asistents, kas savienots ar facebook Messenger , kā arī veikta aptauja gan latviešu, gan angļu valodā, lai noskaidrotu, vai ir kāda atšķirība no latviešu un ārzemnieku viedokļiem saistībā ar virtuālo asistentu.
Biznesa procesu laiksakritīga izpilde
2021
Skūteru servisa biznesa vadīšanai personīgai lietošanai ir daudz biznesa procesu. Šajā rakstā analizēts viens no šiem biznesa procesiem, konkrēti: skūteru piegāde personīgai lietošanai. Šī darba galvenais uzdevums ir pārbaudīt biznesa procesa pareizību, pārliecinoties, ka klients, kas piedalās šajā biznesa modelī, nesaskaras ar tādām problēmām kā skūtera trūkums vietā, kur tam vajadzētu būt, un savlaicīga paziņošana, ka cits klients ir jau aizņēmies izvēlēto skūteru. Darbs sniedz konkrēta biznesa modeļa piemēru ar detalizētu aprakstu gan no klienta puses, gan no lietojumprogrammas puses, ieskaitot datu bāzi.
Pielāgojamu (White-labeled) interneta bāzētu informācijas sistēmu izstrādes aspekti
2022
Bakalaura darbā tika pētīts, kas ir atkārtoti izmantojama sistēma un kādus pienesumus šīs sistēmas izstrāde spēj dot sistēmu izstrādes procesos. Papildus tika pētīts līdz šim oficiāli neapstiprinātais, bet teorijas līmenī izvirzītais atkārtoti izmantojamās sistēmas koeficients, kas palīdz noteikt atkārtoti izmantojamas sistēmas iespējamību, un citi ieteikumi un ievērojamie principi sistēmu atkātotai izmantošanai. Darba procesā tika apskatīts arī personīgais viedoklis, kas ir gūts izstrādājot atkārtoti izmantojamu sistēmu, attiecīgi apstiprinot vai noliedzot līdz šim izvirzītās hipotēzes par atkārtoti izmantojamām sistēmām.
