  1. 11. Improving maintenance scheduling with condition monitoring on the electric distribution grid : An economic analysis comparing corrective and predictive maintenance

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Hugo Vincenti; [2022]
    Keywords : Condition-based maintenance; predictive maintenance; health index; failure rate; maintenance scheduling; sensors; economic analysis; simulation; Tillståndsbaserat underhåll; förebyggande underhåll; hälsoindex; felfrekvens; underhållsplanering; sensorer; ekonomisk analys; simulering.;

    Abstract : A growing use of sensors on the electric grid has opened the door to new methods of asset management: Distribution System Operators are now looking into conditionbased maintenance, as opposed to the traditional corrective or time-based methods. As an emerging field, the methodology must be constructed from the ground, with the little data available. READ MORE

  3. 12. On the friction and failure mechanisms of bearing and gear surfaces lubricated by a novel nanoadditive in highly stressed operating conditions

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Diego Manuel Chamorro Ruz; [2022]
    Keywords : micropitting; nanoadditive; gear; bearing; tribology; rolling contact fatigue;

    Abstract : Obtaining an enhanced lifespan for mechanical transmissions has become a challenge in diverse application sectors. Micropitting as a contact fatigue mechanism has seriously jeopardized the well-being of rolling-sliding elements present for instance in gearboxes. READ MORE

  4. 13. Developement of a numeric tool for fatigue life evaluation of the regulating mechanism in Kaplan runners

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Emil Treitler; [2022]
    Keywords : Fatigue; Kaplan; Hydropower; Turbine;

    Abstract : Kaplan turbines are a type of hydropower turbine with adjustable runner blades. This allows the turbine to alter its power output while maintaining a relatively high efficiency over a wide range of power levels. But these frequent blade angel adjustments exposes the turbines internal mechanism to wear and the possibility of fatigue failure. READ MORE

  5. 14. Willy Loman's Impact on his Own World : A Lacanian Analysis of a Life Lived in Incongruence

    University essay from Högskolan i Gävle/Avdelningen för humaniora

    Author : Can Incegül; [2022]
    Keywords : psychoanalytic theory; Jaqcues Lacan; mirror stage; symbolic stage; language; unconscious; repression; regression; defense mechanisms; Willy Loman;

    Abstract : In the 1949 play The Death of a Salesman, Arthur Miller depicts a man that goes through life without ever really understanding his own place in it. Willy Loman spends his life chasing a dream yet lacks the ability to achieve it. READ MORE

  6. 15. Understanding implementation gaps in honour-related violence & oppression policy : A case study exploring the promises and pitfalls faced by teachers when implementing policy in a Swedish school environment  

    University essay from Uppsala universitet/Statsvetenskapliga institutionen

    Author : Julia Thalin; [2021]
    Keywords : Micro-level policy implementation; Street-level bureaucrats; Policy implementation gaps; Honour-related violence and oppression;

    Abstract : Honour-related violence and oppression has been politically prioritised in Sweden during the past two decades. National policies have been formulated, laws adopted, and the school has been identified as a crucial actor for preventing this type of violence at the local level. READ MORE
