  1. 1. Optimization-Based Geometry Correction Of Blood Flow CFD Simulations Using 4D-Flow Data

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Fritiof Hegardt; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 4D-flow is a powerful tool capable of capturing 3-dimensional, time-resolved flow measurements of blood flow in the body. Their current use is limited by resolution and scan times. A proposed solution is to use Simulation Based Imaging (SBI). LÄS MER

  3. 2. Efficient Barrier Option Greeks using Automatic Differentation

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Gustav Hedin; [2019]
    Nyckelord :Automatic Differentiation; Greeks; Barrier Option; Vibrato Monte Carlo; Mathematics and Statistics;

    Sammanfattning : Automatic Differentiation (AD) is an effective method for calculation of derivatives. It can evaluate an unlimited number of derivatives to a fixed cost relative to the computing time of the original function. The AD technique is used in many fields for large and complex calculations in order to get accurate values of derivatives fast. LÄS MER

  4. 3. Hållbar parkeringsplanering och vikten av rumsliga analyser

    Master-uppsats, KTH/Samhällsplanering och miljö

    Författare :Haeffner Oscar; [2018]
    Nyckelord :Parking; GIS; Mobility; Parking norms; Spatial planning; Parkering; GIS; Mobilitet; Parkeringsnormer; Rumslig planering;

    Sammanfattning : As the population in the Stockholm region continues to increase problems arise regarding how these new inhabitants are to travel across the region in a sustainable way, this at the same time as making sure that municipalities are planning for sustainable land use. Solving the problem with mobility has historically been done through guaranteeing a set number of parking spaces in direct connection to new development through the use of parking norms. LÄS MER

  5. 4. Power system performance when implementing dynamic rating on a wind farm connected transformer

    Master-uppsats, KTH/Elektroteknisk teori och konstruktion

    Författare :Rikard Karlsson; [2017]
    Nyckelord :;

    Sammanfattning : In this study, dynamic transformer rating (DTR) is applied on a medium power transformer thatis in use in the regional transmission grid. The transformer’s rated apparent power is 63 MVA, itis connected between a wind farm at 22kV and the grid, K¨orsb¨arsdalen, at 135kV. LÄS MER

  7. 5. Integration of regulation in Multi-Terminal Direct Current grids design

    Master-uppsats, KTH/Elkraftteknik

    Författare :Léo Dalmar; [2017]
    Nyckelord :;

    Sammanfattning : The supergrid denotes a transmission grid development option at European scalebased on large power corridors enabling to transport electricity from large productioncenters (such as large oshore wind farms) to large consumption centers.Technico-economic studies show that the development of supergrids could provideoverall benefits in terms of : economic welfare, security of supply and integrationof renewables at European scale.
