Beskyttelse av sensitiv informasjon; En studie av norske nettselskapers beskyttelse av sensitiv informasjon.
(Master thesis; Mastergradsoppgave, 2017-06-01)I dag tar de fleste tilgangen til strøm for gitt. Vi forventer at komfyren skal fungere når vi lager middag, at det er varmt vann i dusjen og at lyset tennes når vi trykker på bryteren (Statnett, 2014, 28.11). Nettselskapene i Norge jobber for å opprettholde en sikker og stabil strømforsyning. Dette arbeidet inkluderer beskyttelse av sensitiv informasjon, altså opplysninger om energiforsyningen som ... -
Sikkerhetskultur hos fotballklubber. En studie av frivillighets- og deltidsarbeids påvirkning på sikkerhetskultur
(Master thesis; Mastergradsoppgave, 2017-06-22)Fotballstadioner har ved flere anledninger vært utsatt for uønskede hendelser der fravær av sikkerhetskultur har blitt omtalt som en hovedårsak til hvordan hendelsen kunne oppstå. Denne oppgaven undersøker sikkerhetskulturen ved en stor europeisk fotballklubb som spiller på en stadion med en kapasitet på over 35 000 mennesker. På bakgrunn av at flere tusen mennesker er samlet på et lite avgrenset ... -
Improving mechanical grip on winter tires. Finite element analysis on pressure profile of airless tire compared to conventional tire using ANSYS workbench
(Master thesis; Mastergradsoppgave, 2017-06-22)The harsh climate of the arctic has always been one of the most difficult areas to drive cars in. The severe loss in traction due to snow and icing on the roads, has led to an increased risk of collisions. The winter tires for cars has developed through the years after their introduction in the 1930’s. There have been three revolutionary changes made since then; implement of studs, changing in tread ... -
What similarities can municipalities experience in crisis management?
(Conference object; Konferansebidrag, 2017-06)Municipalities have an important role in crisis management. The Norwegian emergency principles of responsibility, parity and proximity are central, and the government expects municipalities to take care of crises in their area in accordance with the civil protection law. Due to the varying natures of different crises, one can expect crisis management to take different paths. This paper challenges ... -

Fører utsettelsesatferd til økt risiko i trafikken? En studie av bilister
(Master thesis; Mastergradsoppgave, 2016-12-09)Selv om Norge er et av de mest trafikksikre landene i Europa i følge Trygg Trafikk, er det registrert et høyt antall trafikkulykker her til lands med forskjellig skadegrad. Disse utgjør ikke bare en betydelig samfunnsøkonomisk kostnad, men det er også mange familier og personer som blir rammet, derfor er det viktig å kunne forklare hvorfor ulykker oppstår for å kunne begrense kostnadene og skåne ... -
Oxidative stress in two tropical species after exposure to diesel oil
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2016-08-03)Recent offshore petroleum exploration has increased the risks of oil spills worldwide. We investigated biomarker responses to diesel oil exposure in two tropical and subtropical species, the clam Anomalocardia flexuosa and the polychaete Laeonereis culveri. Animals were exposed to oil-spiked sediment at two different concentrations (0.5 L and 1.0 L m−2). Activities of antioxidant enzymes catalase ... -
Baseline levels of oxidative stress biomarkers in species from a subtropical estuarine system (Paranaguá Bay, southern Brazil)
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2016-08-10)Offshore petroleum exploration has increased the risks of oil spills in coastal tropical and subtropical habitats. Monitoring tools are needed to assess and protect environmental health. We determined baseline values of antioxidant biomarkers (CAT, SOD, GPx, GST, MDA) for five ecologically relevant species in a subtropical system in southern Brazil. Regional baseline levels are compared with literature ... -
On RAM performance of production facilities operating under the Barents Sea harsh environmental conditions
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2016-05-19)Oil and gas (O&G) industry is expanding its activities into Arctic offshore, where is characterised with severe operating conditions and less-developed infrastructure. Such conditions affect the reliability, availability, and maintainability (RAM) of offshore O&G plants, operations, and activities through different scenarios. Plant RAM analysis provides key information for decision-making on, for ... -
Availability assessment of oil and gas processing plants operating under dynamic Arctic weather conditions
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2016-03-19)We consider the assessment of the availability of oil and gas processing facilities operating under Arctic conditions. The novelty of the work lies in modelling the time-dependent effects of environmental conditions on the components failure and repair rates. This is done by introducing weather-dependent multiplicative factors, which can be estimated by expert judgements given the scarce data available ... -
Spatiotemporal patterns of particulate matter (PM) and associations between PM and mortality in Shenzhen, China
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2016-03-02)Background: Most studies on air pollution exposure and its associations with human health in China have focused on the heavily polluted industrial areas and/or mega-cities, and studies on cities with comparatively low air pollutant concentrations are still rare. Only a few studies have attempted to analyse particulate matter (PM) for the vibrant economic centre Shenzhen in the Pearl River Delta. ... -
Human reliability assessment (HRA) in maintenance of production process: A case study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-04-02)Human reliability makes a considerable contribution to the maintenance performance, safety, and cost-efficiency of any production process. To improve human reliability, the causes of human errors should be identified and the probability of human errors should be quantified. Analysis of human error is very case-specific; the context of the field should be taken into account. The aim of this study is ... -

Shock Tube. Detail overview of equipment and instruments in the shock tube experimental setup
(Book; Bok, 2015)The shock tube is a device in which a normal shock wave is produced by the interaction of fluids at significantly high-pressure difference. The shock tube is comprised of two sections known as driver and driven sections. These two sections are interacted with the high-speed valve or a bursting disc. When the interaction happens, a shock wave forms almost instantaneously and propagates into the driven ... -
Computational Fluid Dynamic Analysis of the Tesla Valve
(Conference object; Konferansebidrag, 2016-12-08)Serbian-born inventor Nikola Tesla invented the Tesla valve (Tesla's Valvular Conduit) and patented it in 1919. The Tesla valve is unique in the sense that it does not have any moving parts, but it can work as a one-way valve. Nikola Tesla invented this unit without advanced mathematical models, nor with the help of modern computing power. The original Tesla valve consisted of a set of cavities and ... -
