Dynamic Identification and Modelling of a Pantograph
(Master thesis, 2018)The main objective of this thesis is to measure and determine the dynamic properties of a measurement pantograph, and then create a numerical model with the same properties. The purpose of the model is to give a better ... -
Dynamic impact of heavy long vehicles with equally spaced axles on short-span highway bridges
(Journal article; Peer reviewed, 2018)Extremely large trucks with a weight exceeding the standard require a permit before they are allowed to cross the bridges of a specific route. For the purpose of safety, an escort is often ... -
Dynamic lift on an artificial static armor layer during highly unsteady open channel flow
(Journal article; Peer reviewed, 2015)The dynamic lift acting on a 100 mm × 100 mm section of a static armor layer during unsteady flow is directly measured in a series of physical experiments. The static armor layer is represented by an artificial streambed ... -
Dynamic Load Effects and Power Performance of an Integrated Wind–Wave Energy System Utilizing an Optimum Torus Wave Energy Converter
(Peer reviewed; Journal article, 2022)To increase the utilization of wave and other renewable energy resources, an integrated system consisting of an offshore wind turbine and a wave energy converter (WEC) could be used to harvest the potential energy. In this ... -
Dynamic Load Effects on a Submerged Floating Tube Bridge with emphasis on Vortex-induced Vibrations
(Master thesis, 2017)A ferry-free highway is under planning of the Norwegian Public Roads Administration on the south-west coast of Norway. Many of the fjords are characterized as very deep and wide, resulting in a need for innovative, new ... -
Dynamic load on a Francis turbine runner from simulations based on measurements
(Journal article; Peer reviewed, 2014)The frequency of the Nordic power grid has become more volatile during recent years. This gives rise to two effects in synchronous machines. Firstly, as grid frequency changes the rotational speed of synchronous machines ... -
Dynamic load on High Head Francis turbines during start/stop
(Master thesis, 2014)Pressure measurements were performed on the Francis runner in the Waterpower laboratory at NTNU. These measurements were divided into start and stop procedures, with the generator on or off. The suggested method that was ... -
Dynamic loads on Francis turbines
(Master thesis, 2016)New installations of unregulated power to the electrical grid have led to more fluctuations in the grid frequency. Hydropower plants with large reservoirs can provide services to balance the frequency by increasing or ... -
Dynamic Loads on Francis Turbines: An Experimental Study
(Doctoral theses at NTNU;2019:64, Doctoral thesis, 2019)There is an increasing need for stable and flexible renewable energy. This calls for better lifetime predictions for Francis runners, which in turn requires more knowledge on the dynamic loads on the runner blades. This ... -
Dynamic loads on marine propellers due to intermittent ventilation
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:252, Doctoral thesis, 2010)Dynamic Positioning (DP) systems are increasingly replacing traditional positionkeeping methods—such as jack-up barges and anchoring systems—on board ships operating in ever deeper waters. During these operations, the ... -
Dynamic Loads on Tidal Turbine Blades
(Doctoral thesis at NTNU;2016:213, Doctoral thesis, 2016)Tidal turbines convert kinetic energy from tidal currents into electricity in a similar way as wind turbines extract energy from wind. The wind energy industry being more developped, tidal turbine designers use therefore ... -
Dynamic lot-sizing model for new product launches
(Master thesis, 2022)The increasing interest in the market for innovation has become a key characteristic of food supply chains (FSC). New product launches are part of the strategic advantage of a food company; however, new products are ... -
Dynamic metabolism modeling as a decision-support tool for urban water utilities applied to the upstream of the water system in Oslo, Norway
(Journal article; Peer reviewed, 2014)The paper presents, first, the ‘Dynamic Metabolism Model’ (DMM), developed by the authors, followed by an application to the city of Oslo, capital city of Norway. The time period considered for the analysis is 2013-2043. ... -
