1. 1. Geometry of high dimensional Gaussian data

   Kandidat-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

   Författare :Olof Samuel Mossberg; [2024]
   Nyckelord :HDLSS; high dimensional data; stochastic boundedness; asymptotic orthogonality; geometry; multivariate normal distribution; HDLSS; högdimensionell data; stokastisk begränsning; asymptotisk ortogonalitet; geometri; multivariat normalfördelning;

   Sammanfattning : Collected data may simultaneously be of low sample size and high dimension. Such data exhibit some geometric regularities consisting of a single observation being a rotation on a sphere, and a pair of observations being orthogonal. This thesis investigates these geometric properties in some detail. LÄS MER

3. 2. Evaluating aperture shape controller (ASC) in modulated radiation treatments

   Master-uppsats,

   Författare :Vilma Andrén Cederholm; [2023-09-28]
   Nyckelord :Medical physics;

   Sammanfattning : To decrease aperture complexity, the aperture shape controller (ASC) is a recently introduced function in Eclipse external beam planning (Varian Medical Systems, Palo Alto, USA). ASC works within the photon optimizer, minimizing distances between adjacent leaf tips of the MLC. LÄS MER

4. 3. Regional Inequality and Spatial Dependence in Sweden

   Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

   Författare :Samuel Malmström Arfwedson; [2023]
   Nyckelord :Regional inequality; convergence; spatial dependence; spatial econometrics; Sweden; Business and Economics;

   Sammanfattning : Regional inequality is a growing concern in developed countries, as country-level convergence may obscure increasing disparities within countries. This thesis aims to address this concern by examining the dynamics of regional convergence in Sweden from 1980-2022. LÄS MER

5. 4. Collaborative Mapping with Drone Swarms Utilizing Relative Distance Measurements

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Johan Forsman; Carl Tidén; [2023]
   Nyckelord :;

   Sammanfattning : The field of use for unmanned aerial vehicles, UAVs, has completely exploded in the last decade. Today they are used for surveillance missions and inspecting places that are difficult for people to access. To increase the efficiency and robustness in the execution of these types of missions, swarms of cooperating drones can be used. LÄS MER

7. 5. Från röstsedlar till rikedom: Kan demokrati förklara skillnad iBNP per capita? : En multipel regressionsanalys av paneldata

   Kandidat-uppsats, Linköpings universitet/Nationalekonomi; Linköpings universitet/Filosofiska fakulteten

   Författare :Moa Tallroth; Johanna Wyckman; [2023]
   Nyckelord :economic growth; GDP per capita; democracy index; growth theory; ekonomisk tillväxt; BNP per capita; demokratiindex; tillväxtteori;

   Sammanfattning : Det finns stora skillnader i nivån av BNP per capita mellan länder som inte går att förklara med nuvarande teorier om konvergens, det vill säga att fattiga länder kommer att komma ifatt rika länder på lång sikt. I stället verkar skillnaderna i länders inkomstnivå bestå. LÄS MER
