The Control Zendo: A Game of Inductive Logic for Teaching Automatic Control
(Peer reviewed; Journal article, 2023)Board games and card games have been used with some degree of success in the implementation of active strategies for education, since they stimulate problem solving and increase the learning and engagement of the students. ... -
Are you sure it’s an artifact? Artifact detection and uncertainty quantification in histological images
(Peer reviewed; Journal article, 2023)Modern cancer diagnostics involves extracting tissue specimens from suspicious areas and conducting histotechnical procedures to prepare a digitized glass slide, called whole slide image (WSI), for further examination. ... -
Design of switching state-feedback controllers for linear systems subject to asymmetric saturations
(Peer reviewed; Journal article, 2023)This paper considers the problem of controlling a linear system affected by asymmetrical input saturation. The proposed solution is based on using a linear matrix inequality (LMI)-based methodology to find the gains of a ... -
Event-triggered fault-tolerant leader-following control for homogeneous multi-agent systems
(Peer reviewed; Journal article, 2022)In this paper, the design of an event-triggered fault-tolerant control for leader-following consensus in multi-agent systems subject to actuator faults is presented. The problem under consideration is to reduce the control ... -
The Weighted Kalman Filter
(Peer reviewed; Journal article, 2023)This paper proposes a new version of the Kalman filter, referred to as weighted Kalman filter (WKF). In the WKF some recent results on the weighted linearization of nonlinear systems are exploited to incorporate modifications ... -
Impact of extent of resection on outcome from glioblastoma using the RANO resect group classification system: a retrospective, population-based cohort study
(Peer reviewed; Journal article, 2023)Background Extent of resection (EOR) is associated with survival in glioblastoma. A standardized classification for EOR was lacking until a system was recently proposed by the response assessment in neuro-oncology (RANO) ... -
Ostwald ripening of trapped gas bubbles in porous media : A pore-scale perspective
(PhD thesis UiS;747, Doctoral thesis, 2024)Ostwald ripening of gas bubbles is a thermodynamic process for mass transfer, which is significant for both foam-enhanced oil recovery and underground gas storage. During recovery, it can impact the macroscopic efficiency. ... -
The influences of international standards on structural performance and fracture behavior of 3D printed long fiber composite structures
(Peer reviewed; Journal article, 2023)The material properties of the additive manufactured composite structures are usually done following international standards, that show some difference dimensionally. This study focuses on the impact-induced on the tensile ... -
Automatic analysis of X (Twitter) data for supporting depression diagnosis
(Peer reviewed; Journal article, 2023-12)Depression is an increasingly common problem that often goes undiagnosed. The aim of this paper was to determine whether an analysis of tweets can serve as a proxy for assessing depression levels in the society. The work ... -
Learning within the fire and rescue services – addressing fire and rescue personnel’s competence in tunnel fire safety
(PhD thesis UiS;, Doctoral thesis, 2024)Tunnels are a key element of the Norwegian road transport infrastructure. The road tunnel system consists of more than 1200 tunnels with a large variety of safety designs and standards. While many of the Norwegian tunnels ... -
Exploring Pathogenicity in Blastocystis ST7 and ST4: A comparative analysis of virulence factors from known intestinal parasites for pathogenicity assessment in Blastocystis spp.
(Master thesis, 2023)Blastocystis, a unicellular parasite found in the human gastrointestinal tract, has been a topic of study due to its potential pathogenicity. This study identified potential virulence factors within Blastocystis subtypes ... -
Analysere hvordan den norske regjeringen kommuniserer risiko og usikkerhet i forbindelse med kunstig intelligens (AI)
