This report describes the work and results of a computer program used to predict the propagation of air gun noise to long distances in the water column. The acoustic propagation model used is the PlaneRay model.The sound levels found in the computer model was then used together with startle thresholds...
...in terms slump-flow, of self-compacting concrete with crushed aggregate and fines. The results confirm that concrete with crushed fines and aggregate follow the principle of the model originally developed for natural aggregates, and thus that PMM can be adapted to concrete with crushed aggregate....
There are hundreds of PAH compounds, and some of them are known to have negative effect on nature and humans if emitted to the environment. On a regulatory level, the long-term goal is to eliminate PAH emissions. It is important to measure PAH correctly to understand where these pollutants come from...
This study looks at the challenges and opportunities in the deep energy renovation market with prefab elements. An analysis of 39 European projects was conducted, and the results where structured in three topics. It clearly emerges from this analysis that finding the “composition” of the recipe of a...
HyLINE project. The base metals and weld simulated heat affected zones of four pipeline steels, in four different positions of the pipes, have been tested under in-situ electrochemically charged hydrogen conditions and in air as a reference. Metallurgical characterization and hardness testing has also been...
...providers need to claim privacy awareness and document compliance with regulations or face devastating fines. One approach to address these concerns is to use methods specifically developed to assess privacy risks of ITS. The literature lacks such methods, and the complex and dynamic nature of ITS introduces...
Avinor har gitt SINTEF i oppdrag å foreta en støykartlegging av Sandane lufthamn, Anda, etter Miljøverndepartementets retningslinje T-1442/2016. Beregning av støy er utført med NORTIM 4.5 som tar hensyn til topografien ved beregning av lydutbredelse. Det er gjort beregninger for gjennomført trafikk...
...project Vulnerability and security in a changing power system. The main stakeholders of this project are the energy authorities, system operators and network companies. The project has emphasized vulnerabilities in relation to extraordinary events with low probability to occur and high impact on the security...
...model and the associated input data. HyOpt is an optimization model for the design and evaluation of energy systems with a focus on hydrogen-based technology. Given a structure of the energy system plus expected energy demands and costs, the model decides which elements should be included and with...
...will be based on calcined clay or fly ash as a source of reactive silica and alumina in combination with lime and calcium sulphate (e.g. gypsum) and/or calcium carbonate to stabilize special calcium aluminate phases like ettringite and/or calcium monocarboaluminate hydrate, respectively. Gaining strength...
...our experience with parallelizing existing scientific codes by utilizing profiling tools and the OpenMP application programming interface (API) for multi-platform shared-memory parallel programming in C/C++ and Fortran. Profiling is a very good tool to get an indication on which parts of the program...
...results from the activities on surveillance and condition monitoring in work packages WP 5 (2009-2014) and WP B (2015) in the NOWITECH research centre. The research covered both condition monitoring systems, remote inspection technologies and models for estimating and monitoring technical condition of wind...
Incident Response is the process of responding to and handling ICT security related incidents involving infrastructure and data. This has traditionally been a reactive approach, focusing mainly on technical issues. Incident Response Management (IRMA) combines traditional incident response with a proactive...
...under refinement and transformation. To this end we define a schema for the specification of secure information flow properties and show that all security properties defined in the schema are preserved by a notion of refinement. Refinement is a process that requires human guidance and is in general not...
...assessment of non-technical drivers and barriers influencing further development of the hydrobalancing potential from Norway towards European countries. The rising shares of intermittent renewable energy in Europe will increase the needs for balancing and storage capacity, and Norwegian hydrobalancing is interesting...
Spread and growth of zero emission neighbourhoods. This report describes the development of zero emission neighbourhoods and its drivers and barriers towards further development. The Norwegian context is used as a starting point, and the main focus is on technological, market related and societal aspects...
...performed at S°C and 13°C in SINTEFs laboratory. The data are used as input for SINTEF's Oil Weathering Model (OWM} to predict the properties and behaviour of Vale crude oil in a spill situation at sea. The weathering properties are discussed related to oil spill response; mechanical recovery and chemical dispersion...
