Large population growth in cities and environmental concerns across the world puts increasingly higher demands on public passenger transport. In several European cities, including the nine largest urban areas in Norway ...

In this paper theory on cylinder and wind turbine wakes have been studied, and experimental work on the wake behind a wind turbine have been carried out in the Fluids engineering laboratory at NTNU.The objective of this ...

Luftmotstand er den viktigste motstandskraften i sykkelkonkurranser. For å forbedre den aerodynamiske ytelsen blir det brukt tempohjelmer som er spesielt designet for å redusere luftmotstanden. Tempohjelmene som er ...

In order to decrease the average costs of energy, wind turbines are arranged in wind farms where aerodynamic interactions between the turbines occur. When planning and optimizing the performance of a wind farm, these ...

The paper provides a method to estimate the clearance between two flexible risers in tandem arrangement by taking into account the wake interference when subjected to a combined current plus waves flow. The wake interference ...

This study aims to quantify the relationship between pedestrians’ walking speeds and various surface conditions typically associated with a winter environment. The purpose is to enable assessments of the effects of different ...

AM-teknologi har åpnet muligheten for å produsere gitterstruktur metamaterialer som tidligere ikke var tilgjengelig gjennom standard produksjonsmetoder. I senere år har disse materialene sett et skifte fra kun å bli produsert ...

One predicted consequence of global warming is an increased frequency of extreme weather events, such as heat waves, droughts, or heavy rainfalls. In parts of the Arctic, extreme warm spells and heavy rain-on-snow (ROS) ...

This article develops the warranty cost analysis of a two-component in-series system with stochastic dependence. From the perspectives of both the manufacturer and the consumer, the short-run total profits and costs under ...
