  1. 16. Smart Grids and Turkey: An Overview of the Current Power System and Smart Grid Development

    Magister-uppsats, Uppsala universitet/CEMUS; Uppsala universitet/Naturresurser och hållbar utveckling

    Författare :Müge Keskin; [2021]
    Nyckelord :power systems; smart grid; turkey; sustainable development; electrical grid;

    Sammanfattning : Successful integration of the smart grids is crucial for ensuring the efficiency, resiliency, and sustainability of future power systems. With a 46.53% increase in total primary energy supply between 2008 and 2018 (IEA, 2020a), Turkey has the fastest-growing energy market within OECD countries (Erdin and Ozkaya, 2019). LÄS MER

  3. 17. Identifying subarctic river thermal and mechanical ice break-up using seismic sensing

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Stefania Ursica; [2021]
    Nyckelord :Ice break-up; River ice; Subarctic; Thermal melting; Mechanical break-up; Freeze-up; Environmental seismology; Seismic signals;

    Sammanfattning : River-ice break-up in high-latitude regions, despite its brevity, is a fundamental process, representing the most dynamic and complex period of fluvial processes. Moreover, ice break-up has significant cascading ecological effects, with a different severity for mechanical vs. LÄS MER

  4. 18. Influence of Foundation Modelling on the Seismic Response of a Concrete Dam

    Master-uppsats, KTH/Betongbyggnad

    Författare :Stella Harrison; Siri Nöjd; [2021]
    Nyckelord :concrete dam; earthquake; finite element analysis; free-field forces; mass foundation; betong dam; jordbävning; finita element analys; free-field forces; inkluderad bergsmassa;

    Sammanfattning : It is of great importance to ensure the structural safety of dams during earthquakes since a failure may cause catastrophic consequences. Conventional computation of the structural response of dams is based on a simplified approach where the foundation is considered as massless. LÄS MER

  5. 19. 2D Reflection Seismic Imaging of Sparse 3D Data in the Zinkgruvan Mine, Central Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Maryam Abbasian; [2021]
    Nyckelord :2D crooked-line; reflection seismic; sparse 3D; mineralization; Zinkgruvan; 2D modellering; reflektionsseismik; mineralisering; Zinkgruvan;

    Sammanfattning : Zinkgruvan mining area in the southern Bergslagen mineral district of central Sweden holds over 30 million tons of massive sulphide mineralization. The ever-increasing global demand for mineral/metal resources, together with metal consumption growth especially for high-tech purposes has made the exploration of these resources of particular importance.

  7. 20. Estimation of the characteristic in-situ compressive strength class of concrete structures - A case study of the Skuru bridge

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Sara Ahmadiyan; Daniel Mehari; [2021]
    Nyckelord :existing; structures; characteristic; in-situ; compressive; non-destructive; semi-destructive; destructive; cores; EN13791; GCSC; TDOK; UPV; Rebound; Pull-out; Windsor; correlation; calibrate; indirect; direct; estimate; befintlig; konstruktion; karakteristisk; tryckhållfasthet; icke-destruktiv; halv-destruktiv; destruktiv; kärnor; EN13791; GCSC; TDOK; UPV; Rebound; Utdragskraft; Windsor; korrelation; kalibrera; indirekt; direkt; bedöma;

    Sammanfattning : It is inevitable that Structures become older and their intended use changes or the structuralcodes regulations change. In some regions the damage from seismic activities is a possibility.It becomes, therefore crucial to assess the structural capacity of such structures. LÄS MER
