Hydrogen safety in confined spaces
(Doctoral dissertations at the University of South-Eastern Norway;130, Doctoral thesis, 2022-09-02)Unwanted hydrogen releases in confined spaces can be significantly more dangerous compared to open-air scenarios. The transmission towards a zero-emission system results in a growth of hydrogen-driven vehicles which increases ... -
Identification of signals describing pairwise interaction in plankton, bacteria and bacteriophage : a study of model, microcosm and lake
(Doctoral theses at NTNU;2003:54, Doctoral thesis; Peer reviewed, 2003)This study concerns interaction between organisms. Such interactions are often studied through organism abundances over periods of time (time-series). Time-series reflect both internal (biological) and external (environmental) ... -
An Image Processing Framework for High Speed Videos from Combustion and Gas Explosion Experiments
(Doctoral dissertations at the University of South-Eastern Norway;83, Doctoral thesis, 2020-12-18)The method of high speed photography is used to visualize those phenomena which occur so fast that it is impossible to visualize by the normal human eyes.

(Doctoral dissertations at TUC;2015:5, Doctoral thesis; Peer reviewed, 2015-11-12)The Norwegian petroleum industry has developed a standard for the technical safety of offshore installations (NORSOK S-001, 2008). When dimensioning accidental load with this standard, the deluge or fire water spray may ... -
Impact erosion by solid particles in gas-particle flows
(Doctoral thesis, 2021-06-18)Mass loss of inner wall surface due to particle impact, also referred as erosive wear, is a common challenge encountered in industrial pneumatic conveying systems. Previous studies have shown that erosion is a process ... -
Impact of climate change and habitat degradation on two endangered reptiles: the Guatemalan beaded lizard and the Olive Ridley sea turtle
(Doctoral dissertations at the University of South-Eastern Norway;165, Doctoral thesis, 2023-06-15)Climate change and habitat degradation are the main threats to non-avian reptiles. Non-avian reptiles are a clade of ectothermic vertebrates that include turtles, alligators, lizards, amphisbaenians, and snakes. As ectotherms, ... -
Impact of single crystal properties on underwater transducer designs
(Doctoral dissertations at the University of South-Eastern Norway;154, Doctoral thesis, 2023)The ongoing robotic revolution in oceanic science puts new requirements on underwater transducers. Small platforms require compact multi-purpose transducers, and there is limited space available for the electronics. ... -
Implementing structured vision assessment in stroke care services: The KROSS knowledge translation project
(Doctoral thesis, 2022)Background Stroke is a leading cause of death and disability in Norway and internationally. Many functions can be affected by stroke and vision is one of them. Visual impairments (VIs) affect 60% of all stroke survivors, ... -
Importance of air and soil temperatures for bioclimatic delimitations in Norwegian mountains
(Doctoral dissertations at the University of South-Eastern Norway;4, Doctoral thesis, 2018-06-18)Distribution limits of plants in relation to climatic variables have long interested ecologists. High latitudes and altitudes house distribution limits of forests, treelines, treeline ecotones and vascular plants in alpine ... -
Improved Multiphase Flow Performance Using AICV and its Potential Impact on Reservoir Recovery
(Doctoral dissertations at the University of South-Eastern Norway;198, Doctoral thesis, 2024-06-14)The global energy demand is growing, and oil and gas supply and consumption will evolve in the coming years. It is important to maintain the current oil production to meet the global energy demand. A major challenge in oil ... -
Improved packaging techniques for LWIR microbolometers
(Doctoral dissertations at the University of South-Eastern Norway;164, Doctoral thesis, 2023)A new generation of Infrared (IR) camera sensors, based on MicroBolometer Arrays (MBA) has been developed. This technology is lower cost and has no need for active cooling, unlike the previous generation. It, therefore, ... -
Improvement in refractive precision for intraocular lens power calculations in patients with a history of laser vision correction for myopia
(Doctoral dissertations at the University of South-Eastern Norway;99, Doctoral thesis, 2021-05-28)In Cataract surgery and refractive lens exchange (RLE) planning, calculations of intraocular lens (IOL) power depend on, at a minimum, the measurement of corneal curvature and the axial length of the eye. In patients without ... -
Inductive impedance matching network for Magnetic Resonant Wireless Power Transmission
(Doctoral dissertations at the University of South-Eastern Norway;152, Doctoral thesis, 2023)Inductive wireless power transfer is getting more and more attention as the demand for mobile electronic devices grows. There are already well-functioning wireless charging systems for smartphones, tablets, and electric ... -
Integratable opto-microfluidic devices for sensitive detection of bio-analytes
(Doctoral Theses at Buskerud and Vestfold University College;3, Doctoral thesis, 2014)The expensive fabrication of current optical microfluidic devices is a barrier to the successful implementation of these devices in low-cost, high-sensitivity biosensing systems. Organic photodiodes (OPDs) have great ... -
