Security breaches still continue to flourish despite of the many technical measures in place. More often than not, the human users get the blame. Social engineering attacks use various manipulation techniques to fool users into giving away sensitive information or make security mistakes that are...
...[Context] Requirements elicitation is an essential activity to ensure that systems provide the necessary functionality to users, and that they are fit for purpose. In addition to traditional ‘reductionist’ techniques, the use of observations and ethnography-style techniques have been proposed to...
The paper presents the conceptual design of a prototype experimental facility for mixing jet-type flow condensers investigations when the steam in exhaust gases is condensed on the water jet in the presence of CO2. The proposed experimental test rig was designed to give abilities to investigate the...
Electricity prices in Norway increased to new levels, never seen before, starting in the late summer of 2021. Electricity prices in Europe were even higher and Norway, as part the European electricity market, exported electricity even if reservoir levels were rather low (cf. Figure 5 week...
Industrial off-gas can be a resource, but regulatory uncertainties are often in the way of fully leveraging it. Re-using gases like CO₂ from industrial off-gas is desirable but will require large investments. The economic risk is increased by the fact that the rules for how you pay for emissions is...
This report evaluates the efficacy of a cooperative intelligent i transport systems (C-11s) technology designed to communicate traffic light information to connected vehides. As a part of the NordicWay 3 project, a sample of 15 drivers participated in a controlled study using an application...
We propose and investigate a bidirectional device-to-device (D2D) transmission scheme that exploits cooperative downlink non-orthogonal multiple access (NOMA) (termed as BCD-NOMA). In BCD-NOMA, two source nodes communicate with their corresponding destination nodes via a relaying node while...
The extent to which navigation signals in the E6 band may be impacted by shared spectrum allocations might be underappreciated. This paper presents top-level observations from a multi-year international radio frequency interference (RFI) monitoring project covering all L-band global navigation...
Defects in pulsed-laser deposition grown have been investigated using thermal admittance spectroscopy and secondary ion mass spectrometry (SIMS). A film was grown on either a tin-doped indium oxide or an aluminum-doped zinc oxide buffer layer on a sapphire substrate functioning as back contact layer...
The maximum efficiency of solar cells utilizing a single layer for photovoltaic conversion is given by the single junction Shockley–Queisser limit. In tandem solar cells, a stack of materials with different band gaps contribute to the conversion, enabling tandem cells to exceed the single junction...
Local Na-coordination and dynamics of Na2–xZn2–xGaxTeO6; x = 0.00 (NZTO), 0.05, 0.10, 0.15, 0.20, were studied by variable-temperature, 23Na NMR methods and DFT AIMD simulations. Structure and dynamics were probed by NMR in the temperature ranges of 100–293 K in a magnetic field of 18.8 T and from...
This paper proposes a dc-voltage control design for a dc-dc converter with saturation nonlinearity. The suggested implementation is only slightly altered from the traditional structure of cascaded PI-controllers for handling the nonlinearity introduced by the input voltage limitation. Singular...
The ability of cells to move and migrate is required during development, but also in the adult in processes such as wound healing and immune responses. In addition, cancer cells exploit the cells’ ability to migrate and invade to spread into nearby tissue and eventually metastasize. The majority of...
Turbulent wind fields are known to be a major driver for structural loads and power fluctuations on offshore wind turbines. At the single-turbine scale, there exist well-established design standards based on wind spectra and coherence functions calibrated from years of measurements, which are used...
