  1. 11. Modelling and Dynamic Performance of Hydropower in Frequency Regulation : Modelling of Double Regulated Hydropower Turbines

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

    Author : Kristinn Arnar Ormsson; [2021]
    Keywords : Frequency Containment Reserves FCR ; Hydropower; Double regulated DR turbine; Non-linear modelling; Simulink.; Frekvensreserv FCR ; vattenkraft; dubbelreglerad DR turbin; icke-linjär modellering; Simulink.;

    Abstract : The frequency of the Nordic power system has been increasingly deviating outside the normal frequency band (50 ± 0.1 Hz) in the past two decades. In an effort to counteract this, the Nordic Transmission System Operators (TSOs) have proposed new and stricter requirements on the units participating in Frequency Containment Reserve (FCR) market.

  3. 12. Towards Ca2+ Responsive Reticular Materials. An Evaluation of Suitable Conditions for Self-Assembly of the Protein S100G

    University essay from Lunds universitet/Biofysikalisk kemi

    Author : Andreas Carlsson; [2021]
    Keywords : protein material; domain swapping; EF-hand; calbindin D9k; Ca2 dependent; aggregation; S100G; protein design; biophysical chemistry; Biology and Life Sciences;

    Abstract : Att bygga material av proteiner är en konst som våra kroppar är specialister på. Men när vi medvetet försöker designa proteinmaterial, så blir det tydligt hur komplexa och svårstyrda biofysikens lagar är. READ MORE

  4. 13. Modelling Competitive Sorption of Per- and Polyfluoroalkyl Substances (PFASs) to Soil and Sorbents

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

    Author : Linnea Georgii; [2021]
    Keywords : PFAS; modelling; competitive sorption; adsorption; isotherms; PFAS; modellering; konkurrenseffekter; adsorption; isotermer;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) have become contaminants of increasing concern to society due to the contamination of drinking water and the ecosystem. A better understanding of the sorption and transport of PFASs in soil systems is urgently needed, however there have been few studies dedicated to investigating competitive sorption among PFASs, and there is no available model to model such effects.

  5. 14. The process behind the delimbing of trees

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Martin Sunnälv Persson; [2021]
    Keywords : Thinning; MATLAB; branch distribution; debranching; Gallring; MATLAB; grendistribution; avgrening;

    Abstract : In modern forestry, two types of machines are generally used for thinning, harvesters and forwarders. These machines are large and weigh several tens of tons, this means that they damage the ground when they drive around in the woods. READ MORE

  6. 15. Strukturkalkens inverkan på jordmotstånd : analys av mätningar på det horisontella och vertikala motståndet

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Claes Sjöberg; Jens Kårhammer; [2021]
    Keywords : strukturkalkning; dragkraftsbehov; jordmotstånd; penetrometermotstånd; aggregatbildning; lerjord; pH;

    Abstract : Genom tillförsel av strukturkalk, som är en jordförbättringsåtgärd till lerjord, kan flera positiva effekter uppnås. Forskning har tidigare visat att strukturkalkning kan ge stabilare aggregat, och kan bidra till minskat fosfor läckage samt bättre vatten och näringshållande förmåga. READ MORE
