  1. 21. 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. 22. Betes- och utfodringsstrategier för förbättrad juverhälsa i samband med värmestress

    University essay from SLU/Dept. of Clinical Sciences

    Author : Elna Laxmar; [2022]
    Keywords : mjölkproduktion; juverhälsa; värmestress; betesstrategi; utfodring;

    Abstract : Värmestress hos mjölkkor definieras av en oförmåga att bibehålla normal kroppstemperatur, vilket leder till nedsatt produktion och djurvälfärd. Sommaren 2018 uppmärksammandes som en av de varmaste perioderna i Sverige sedan 1951 och påföljderna för svenska mjölkföretagare var kännbara. READ MORE

  4. 23. Just Sustainability Transitions in the Blue Economy: Towards Blue Justice in Small-Scale Artisanal Fisheries in the Pacific of Costa Rica

    University essay from Lunds universitet/Ekonomisk-historiska institutionen

    Author : Judith Baeta Humanes; [2022]
    Keywords : blue economy; small-scale artisanal fisheries; just transitions; blue justice; Costa Rica; fieldwork; Social Sciences; Business and Economics;

    Abstract : The blue economy emerged as sustainable, inclusive and equitable alternative to traditional oceans economy. However, the current paradigm of oceans as development spaces has led to an acceleration of competing uses of marine resources causing ecosystem deterioration and human rights abuses that disproportionately affect vulnerable small-scale fisheries.

  5. 24. The future of farm succession : how alternative financial solutions could facilitate Swedish farm successions

    University essay from SLU/Dept. of Economics

    Author : Ebba Sundström; Joel Jonsson; [2022]
    Keywords : Farm succession; capital structure; information asymmetry; alternative financial solutions;

    Abstract : This thesis develops an understanding of how Swedish beginning farmers choose between different sources of financing and examine how these preferences could be used in assessing a new alternative financial solution to facilitate farm successions. This has been done through a qualitative case study were six young farmers in the region of Mälardalen, facing a generational renewal, have been interviewed. READ MORE

  6. 25. CFD Based External Heat Transfer Coefficient Predictions on a Transonic Film-Cooled Gas Turbine Guide Vane : A Computational Fluid Dynamics Study on the Von Karman Institute LS94 Test Case

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Rosalie Johnsson; Lilian Asiegbu; [2022]
    Keywords : gas turbine; turbine inlet guide vane; film-cool; film cool; Computational Fluid Dynamics; CFD; heat transfer coefficient; Shear Stress Transport k-ω; SST k-ω; Scale Resolving Hybrid; SRH; turbulence modelling;

    Abstract : The turbine inlet guide vanes of a gas-turbine are subjected to extreme hot gas temperatures which increases the risk of mechanical failure and overall reduces the component lifespan. Hence, it is of great interest for gas-turbine manufacturers to establish methods for accurately estimating the temperature distribution along the vane surface. READ MORE
