(Chapter, 2022)The primary goal of this ongoing questionnaire is understanding the state of affairs in terms of big data utilization in Norwegian high-tech enterprises. By asking 24 questions to employees at partner organizations comprising ... -
User-centered Data Driven Approach to Enhance Information Exploration, Communication and Traceability in a Complex Systems Engineering Environment
(Chapter, 2022)Organizations working on complex engineering projects have data scattered across many different systems. The data is often disconnected, and its potential remain largely untapped. Enterprises large and small find it difficult ... -
A Model for an Effective Learning Process in Higher Education: An Example from Three User Cases
(Peer reviewed; Journal article, 2022)Knowledge is the most important asset in education. Knowledge Management has been the focus for many years in higher education. Recently, universities have embraced innovative processes that could foster a better learning ... -
Applying Systems Thinking for Early Validation of a Case Study Definition: An Automated Parking System
(Chapter, 2022)Case study research and industry-as-laboratory research are well-known research methods in industry–academia collaboration research projects. Defining a case study well in the early phase of an industry–academia complex ... -
Including pervasiveness and ubiquity into the HE curriculum: Experience from the USN
(Journal article; Peer reviewed, 2021)Pervasive and ubiquitous environments, where the boundary between physical items and software artifacts are disappearing, have had a significant impact on education, because it is a double edge sward. Pervasiveness is ... -
Two-dimensional quantum motion of a levitated nanosphere
(Peer reviewed; Journal article, 2022)We report on the two-dimensional (2D) dynamics of a levitated nanoparticle in an optical cavity. The motion of the nanosphere is strongly coupled to the cavity field by coherent scattering and heavily cooled in the plane ... -
