    • Changing patterns in the process of digital transformation initiative in established firms : the case of an energy sector company 

      Dang, Duong; Vartiainen, Tero (Association for Information Systems (AIS), 03.06.2020)
      Rapid digitalization and technological change are disrupting traditionally successful business models. This motivates firms to adopt new strategies based on digital technologies; such new strategies are often referred to ...
    • Citizen science in information systems research : evidence from a systematic literature review 

      Mäkipää, Juho-Pekka; Dang, Duong; Mäenpää, Teemu; Pasanen, Tomi (07.01.2020)
      Citizen science refers to partnerships between scientists and the public in scientific research. Citizen science is considered as an emerging approach for conducting research in the field of information systems (IS). However, ...
    • Decidable Variable-Rate Dataflow for Heterogeneous Signal Processing Systems 

      Ma, Yujunrong; Wu, Jiahao; Bhattacharyya, Shuvra S.; Boutellier, Jani (IEEE, 14.05.2020)
      Dynamic dataflow models of computation have become widely used through their adoption to popular programming frameworks such as TensorFlow and GNU Radio. Although dynamic dataflow models offer more programming freedom, they ...
    • Digital predistortion for 5G small cell : GPU implementation and RF measurements 

      Pascual Campo, Pablo; Lampu, Vesa; Meirhaeghe, Alexandre; Boutellier, Jani; Anttila, Lauri; Valkama, Mikko (Springer, 21.12.2019)
      In this paper, we present a high data rate implementation of a digital predistortion (DPD) algorithm on a modern mobile multicore CPU containing an on-chip GPU. The proposed implementation is capable of running in real-time, ...
    • Errors and Complications in SQL Query Formulation 

      Taipalus, Toni; Siponen, Mikko; Vartiainen, Tero (Association for Computing Machinery, 08 / 2018)
      SQL is taught in almost all university level database courses, yet SQL has received relatively little attention in educational research. In this study, we present a database management system independent categorization of ...
    • Institutional Logics and Their Influence on Enterprise Architecture Adoption 

      Dang, Duong (Taylor & Francis, 17.01.2019)
      Enterprise architecture adoption (EAA), often ironically known as “ineffective adoption,” is frequently marked by poor utilization and signals of failure. To date, comprehensive examinations of which factors influence EAA ...
    • Institutional perspectives on the process of enterprise architecture adoption 

      Dang, Duong; Pekkola, Samuli (Springer, 09.07.2019)
      Organizations often adopt enterprise architecture (EA) when planning how best to develop their information technology (IT) or businesses, for strategic management, or generally for managing change initiatives. This variety ...
