  1. 21. MIGRATION OF FLUID DURING DEFORMATION OF MOLTEN DEUTRATED ICE USING 3D IMAGE ANALYSIS

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Uzochukwu Damian Akwuba; [2021-09-14]
    Nyckelord :Ice; Deformation; Tomography; Fluid Migration; Fractures;

    Sammanfattning : The behaviour of in ltrating and intergranular uid in an ice body is essential in understanding the de ection of the glacier body. The movement of the uid during deformation is most naturally controlled by compressive stress and temperature gradient which is important in understanding the behaviour of the glacier body. LÄS MER

  3. 22. Fördelar med lågviktsdrivlina i vindkraftverk

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Johan Rosén; [2021]
    Nyckelord :Cost; Lightweight; Nacelle; Wind turbine; Kostnad; Lågviktsdrivlina; Nacell; Vindkraftverk;

    Sammanfattning : I dagsläget finns det en mängd olika storlekar på vindkraftverk, allt från små landbaserade vindkraftverk på några hundra kilowatt till havsbaserade kraftverk på upp till 14 MW. Bland de största vindkraftverken ute till havs, är direktdrivna vindkraftverk dominerande på grund av en högre driftssäkerhet och livslängd på komponenterna. LÄS MER

  4. 23. Design and Evaluation of a Novel Conveyor Utilizing a Screw Mechanism to Move Objects With Integrated Racks

    Master-uppsats, KTH/Mekatronik

    Författare :Måns Nilsson; Mathias Nils Edvin Nordqvist; [2021]
    Nyckelord :Screw Conveyor; Intralogistics; Material Handling; Thread Meshing; Worm rack drive; Brushless motor; Skruvtransportör; Intralogistik; Materialhantering; gängingrepp; Snäckskruv och kuggstång; borstlös motor;

    Sammanfattning : Intralogistics, or material handling, traditionally use roller or chain conveyors to moveo bjects and goods in factories and warehouses. One negative aspect of the traditional types of conveyors is that they are expensive, as they are comprised of many moving parts. LÄS MER

  5. 24. Drivers of health-tech innovation in Region Skåne

    Magister-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Nicole Skoglund; [2021]
    Nyckelord :innovation; digitalization; drivers of innovation; healthcare innovation; sustainable development; health-tech; technological change; cloud technologies; Business and Economics;

    Sammanfattning : In direct comparison with other industries, technological innovations are slow to diffuse within the healthcare sector. Scholars estimate that the failure rate of implementing innovation within healthcare organizations range between 30% to 90%. This poses a question as to why the healthcare sector is lagging in the adoption of new technologies. LÄS MER

  7. 25. Quantification of Drive Cycles for Evaluating Motor Efficiency

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :David Bergman; [2021]
    Nyckelord :drive cycle; electrical motor; quantification; resolution;

    Sammanfattning : Due to the goals made by the European Union as well as the country of Sweden regarding the desired decrease of the ongoing greenhouse gas emissions, electrical alternatives have increased enormously in the industry and the automotive areas in recent years. By going from petrol-powered vehicles to electrical vehicles, the transport sector has the potential to produce zero direct emissions. LÄS MER
