    University essay from KTH/Fysik

    Author : Ida Hägnestrand; [2023]
    Keywords : Gamma Knife; Cone-beam computed tomography; Image quality; Image reconstruction; Co-registration; Contrast; Uniformity; Spatial resolution; Scatter correction; Wiener filter; Noise filter; Patient positioning; Stereotactic radiosurgery; Gammakniv; Strålkniv; Cone-Beam Computed Tomography; Bildkvalitet; Bildrekonstruktion; Co-registrering; Kontrast; Uniformitet; Spatial upplösning; Spridningskorrigering; Wienerfilter; Brusfilter; Stereotaktisk strålkirurgi;

    Abstract : The Gamma Knife is a non-invasive stereotactic radiosurgery system used for treatments of deep targets in the brain. Accurate patient positioning is needed for precise radiation delivery to the target. READ MORE

  3. 2. Link Adaptation in 5G Networks : Reinforcement Learning Framework based Approach

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

    Author : Siva Satya Sri Ganesh Seeram; [2022]
    Keywords : Link Adaptation; OLLA; AMC; Reinforcement Learning; DDPG; BLER; Länkanpassning; OLLA; AMC; förstärkningsinlärning; DDPG; BLER;

    Abstract : Link Adaptation is a core feature introduced in gNodeB (gNB) for Adaptive Modulation and Coding (AMC) scheme in new generation cellular networks. The main purpose of this is to correct the estimated Signal-to-Interference-plus-Noise ratio (SINR) at gNB and select the appropriate Modulation and Coding Scheme (MCS) so the User Equipment (UE) can decode the data successfully.

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

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Fritiof Hegardt; [2022]
    Keywords : Technology and Engineering;

    Abstract : 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). READ MORE

  5. 4. Beyond the Turning Point: The Environmental Kuznets Curve for CO2 Emissions in Romania

    University essay from Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Author : Mara Balasa; [2022]
    Keywords : environmental Kuznets curve; autoregressive distributed lag; Granger causality; Romania;

    Abstract : This thesis studies the long-run relationship between environmental degradation measured by carbon dioxide (CO2) emissions per capita and economic growth measured by gross domestic product per capita in Romania, between 1968 and 2018. The study is conducted using the environmental Kuznets curve (EKC) framework and the autoregressive distributed lag bounds test for cointegration. READ MORE

  6. 5. Is there a long-run relationship between stock prices and economic activity and are stock returns a leading indicator for economic growth? : Evidence from the Scandinavian countries: Sweden, Norway and Denmark

    University essay from Örebro universitet/Handelshögskolan vid Örebro Universitet

    Author : Anna Carlsson; Jonas Holm; [2021]
    Keywords : ;

    Abstract : The purpose of this paper is twofold. First, the Johansen cointegration framework is applied to analyze the long-run relationship between stock prices and economic activity, using GDP as a proxy. In consideration of a long-run relationship a vector error correction model (VECM) is estimated to analyze the parameters of cointegration. READ MORE
