In this paper we solve an eigenvalue problem on a circular membrane with fixed outer boundary by using a finite element method, where an element is represented as an expo-rational blending triangle. ERBS triangles combine properties of B-spline finite elements and standard polynomial triangular elements. The overlapping of local triangles allows us to provide a flexible handling of the surface while ...

"There is a need for a stretcher, which can also function as a sledge, especially for rescue missions in arctic climate, as the extraction point may only be accessible by people by foot or on skies. Existing solutions have some flaws, and some are not specifically designed for arctic conditions. The task is to develop a multi-purpose stretcher, operable by two members of the rescue team. In ...

This paper discusses the Inspiria charging station facility in Norway, which enables various charging point operators to offer different charging systems for different purposes and needs. The charging station can be considered a specific case of a shared economy, as users share the same infrastructure and much of the same space. By utilizing new technology and the differences in charging needs in ...

This paper presents the technological developments and the policy contexts for the project “Autonomous Robotic Sea-Floor Infrastructure for Bentho-Pelagic Monitoring” (ARIM). The development is based on the national experience with robotic component technologies that are combined and merged into a new product for autonomous and integrated ecological deep-sea monitoring. Traditional monitoring is ...

This work attempts to model the dynamic behavior of Carbon Fiber Reinforced Polymer (CFRP) shell structure subjected to water shock wave to improve the results presented in the study by Khawaja et al., 2014. In the previous study, the real physical problem was simplified by decoupling the fluid and the structural phenomena, applying the recorded experimental fluid pressure load to the CFRP shell ...

The number of good sites in less exposed locations for aquaculture farming is limited. Trends are now that the fish cages are increasing in both width and depth as well as more weather-exposed locations, are taken into use. As the net cages continue to increase in size, so does the material costs. The design of the sea cages should be modified for safe and reliable use in remote offshore locations. ...

The project objective is to investigate into luminescent coating materials that can be used in marking the roads in high-north. The idea of the project is not entirely new, and efforts have been worldwide to find an energy efficient solution to the street lights. Earlier work conducted in the Netherlands showed quite promising results. However, the challenges include weatherproofing the coat such ...

This report presents the design and simulation of code and carrier tracking system for a GNSS receiver. The GNSS receiver processes the signal sent by satellites in space. These signal contain carrier wave signal, ranging code and navigation data in encrypted form. To demodulate the navigation data, the processing block should accurately track the phase of incoming code and the frequency of incoming ...

This paper describes a framework for simulating household appliances in Simulink. Typical Norwegian household equipment have been analyzed based on their characteristic behavior, to establish the requirement for synthesizing and recreating their current waveform, harmonic currents and phase shift. Both detailed simulation of the current waveform and RMS currents for simulation over longer time periods ...

Oppgaven retter fokus mot hvordan vi tradisjonelt planlegger fremdriften i byggeprosjekter i dag, og hvordan digitale verktøy som 4D BIM klarer å effektivisere planleggingen. I tillegg vil også Lean filosofien befinne seg i ulike planleggingsmetoder, man ønsker å skape verdi både for selskapet, kundene og alle andre deltakere som er involvert i prosjektet. Dermed ønsker man å skape flyt i produksjonen ...
