Policy-based management is an approach to the management of systems with respect to issues such as security, access control and trust by the enforcement of policy rules. This paper addresses the problem of integrating the requirements imposed by a policy with the system development process. In order...
... one spill sample and three source samples, have been prepared by SINTEF. The Spill sample was collected from a buoy in a drifting oil slick in the North sea close to the border between the Norwegian and British sector. There are several suspected sources, both from platforms and passing ships. Three...
MPRI/Fisheries and Ocean-DFO Canada, ITOPF (R&D Award) and the Norwegian Coastal Administration (NCA). In order to meet new requirements for lower sulfur oxides (SOx) emissions to the air, new generation of low sulfur marine fuel oil (LSFO) are now replacing the traditional Intermediate fuels and heavy fuel...
Background and research questions Research has shown that loss data on asset level from insurance companies have high utility value for local municipalities. These data can foster better understanding of the risks linked to nature events and surface-water flooding, in turn facilitating well-informed...
The main aim of the work has been to do modeling and calculations of the energy use, embodied emission and the total CO2-emissions for a typical Norwegian office building. The goal is to find the most important parameters in the design of a zero emission office building, according to the current ZEB...
...ground gear of the MultiSEPT project. spreading of the SCSG and rockhopper gear was measured by use of MARPORT distance sensors. Bottom contact was monitored by use of SCANMAR trawl sensors and by underwater cameras mounted in the headline and belly of the trawl. Fishing efficiency of these two gears...
Europakommisjonens ambisjon om å bli verdens første klimanøytrale kontinent innen 2050 er avhengig av digitale teknologier og løsninger som kunstig intelligens (KI), 5G, tingenes internett (IoT), skytjenester og "edge computing" for effektiv utnyttelse av energi og ressurser. Men hvor smarte er...
CORAS security risk modelling language is a customised graphical language for com- munication, documentation and analysis of security threat and risk scenarios. We present a textual syntax and a structured semantics for each of the five different types of CORAS di- agrams, together with step-by-step...
...temperature and precipitations measurements are observed in this area. It is anticipated that this will pose a serious threat to existing infrastructure and will impose additional challenges for new developments. Adaptations of existing and future infrastructure to changes in climate for safety and serviceability...
Sirkulærøkonomi handler om å utnytte ressursene våre best mulig. Det sikrer bærekraft og verdiskaping på både kort og lang sikt. Sirkulærøkonomien prøver å lukke materialsløyfene for å hindre at mulige ressurser går tapt. Vi ønsker at ressursene skal vare lenger, og derfor at ressursenes verdi og...
...temperatures and reduced snow cover, which threatens the possibility to exercise winter sports activities near populated areas in the future. Temperature Independent Snow (TIS) production can contribute to increase the snow reliability for winter sport. However, this method is very energy intensive and to reduce...
...describes a study of day-ahead (DA) and intraday (ID) trade for a hydropower producer with a single reservoir and power plant. The study simulates the trade decisions and plant operation in a rolling-horizon setup where DA decisions are reoptimized on a daily basis and ID decisions are reoptimized on an...
STAS software, for the system dynamics and control of wind power plants. An overview is given of the theory behind the STAS software, and the architecture of the system model. A wind turbine control system has been designed, which is well-suited to the STAS model and the upcoming research on plant control...
...performed activities and deliverables within the Monitoring of Arctic lnfrastructure project (MonArc) in 2019 and gives references to field data records collected in 2017-2019. Settlements of surveyed buildings in 2017-2019 are presented. The performed activities include scientific and logistical planning...
...research framed within transition studies and the multi-level perspective (MLP) is used to discuss the role Norwegian hydrogen production may play in sustainable energy transition towards 2050. Ongoing initiatives and stakeholder perspectives on drivers and barriers are discussed. The focus is on the...
...160 small and medium-sized waterworks in Norway are using membranes for treatment of raw water with high content of natural organic material (NOM). Most of the membrane-based waterworks use nanofiltration (NF) as treatment process. The first NF facilities were commissioned late 1980s, and it is anticipated...
New ideas are needed as to how we can develop and provide housing for the disabled. This report examines the practices of six Norwegian municipalities, which in a variety of ways are looking to enable disabled residents to build or buy and own their own homes. The survey has confirmed some previous findings:...
The IEA HPT Annex 49 "Design and integration of heat pumps for Nearly Zero Energy Buildings" deals with the design and integration of heat pumps as core component of the HVAC system for Nearly or Net Zero energy buildings (NZEB). The IEA HPT Annex 49 has been structured into four tasks which comprise...
The viscosities and melting points of SiO2-rich oxide melts depend on their composition. This work presents viscosities, calculated in FactSage, for various binary oxide melts consisting of SiO2 and various levels of a secondary oxide from: [Fe2O3, Al2O3, CaO, K2O]. Also included are the calculated...
...the temperatures, airflows and relative humidity in all the ducts very close to the air handling unit were needed to calculate the field efficiency. The initial goal was to measure in nine different buildings and give some inputs regarding the discrepancy between rated and measured efficiency in buildings...
