  1. 1. Movement of Foxfonna rock glacier in Svalbard between 2017-2019

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Elias Lundström; [2020]
    Keywords : rock glacier; Svalbard; UAV; photogrammetry; movement detection; permafrost; Earth and Environmental Sciences;

    Abstract : The movement of a rock glacier located at the bottom of the Foxfonna glacier, Svalbard, Norway, was studied through the use of photogrammetry and feature tracking software, between the years of 2017-2019, as well as elevation changes between 2009 and 2019. This could aid in further knowledge about the rapid velocity changes of rock glaciers in a continuous permafrost environment. READ MORE

  3. 2. Detection and removal of wind turbine ice : Method review and a CFD simulation test

    University essay from Högskolan i Gävle/Energisystem

    Author : Ismael Bravo Jimenez; [2018]
    Keywords : renewable energy; wind turbine; ice accretion; flow simulation; CFD; wind turbine performance; anti-icing methods; de-icing methods.;

    Abstract : Nowadays, the energy sector is facing a huge demand that needs to be covered. Wind energy is one of the most promising energy resources as it is free from pollution, clean and probably will arise as one of the main energy sources to prevent global warming from happening. Almost 10% of the global energy demand is coming from renewable resources. READ MORE

  4. 3. Competing Discourses in Aircraft Cabin Air Contamination: How to Define a Problem

    University essay from Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Arie Adriaensen; [2017]
    Keywords : FLMU06; Cabin Air Quality; Cabin air contamination; Bleed air contamination; Fume Events; Aviation; Social Sciences;

    Abstract : In the scientific literature and in the media there is a growing concern about toxins in aircraft originating from the air conditioning system as a result from pyrolised jet engine and hydraulic oil, and more recently also de-icing fluid. Many crews have reported long-term neurological and respiratory health effects, but also acute impairment or even incapacitation while performing their flight duties. READ MORE

  5. 4. Evaluation of field tests of different ice measurement methods for wind power : focusing on their usability for wind farm site assessment and finding production losses

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Helena Wickman; [2013]
    Keywords : wind power; cold climate; ice detector; production loss; site assessment; vindkraft; kallt klimat; isdetektor; produktionsförlust;

    Abstract : The favorable wind recourses in many cold climate regions make them interesting for development of wind farms. However, with the cold climate come drawbacks due to icing. Production losses, fatigue loadings, ice throws and increased noise are some of the more severe issues that have to be addressed. READ MORE

  6. 5. Measuring routines of ice accretion for Wind Turbine applications : The correlation of production losses and detection of ice

    University essay from Institutionen för fysik

    Author : Viktor Carlsson; [2010]
    Keywords : wind power; atmospheric icing; anti icing; de-icing; icing sensors; icing measurements; relative humidity;

    Abstract : Wind power will play a major role in the future energy system in Sweden. Most of the major wind parks are planned to be built in sites where the cold climate and atmospheric icing can cause serious problems. This underlines the importance of addressing these issues. READ MORE
