1. 6. Gravity water waves over constant vorticity flows: from laminar flows to touching waves

   Master-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

   Författare :Francisco Gonçalves Jorge Dias de Carvalho; [2023]
   Nyckelord :Partial differential equations; Water waves; Euler equations; Free boundary problem; Bifurcation theory; Nonlinear functional analysis; Hilbert transform; Mathematics and Statistics;

   Sammanfattning : In a recent paper, Hur and Wheeler proved the existence of periodic steady water waves over an infinitely deep, two-dimensional and constant vorticity flow and subject to gravity whose profile overhangs, among which, waves whose surface touches at a point, enclosing a bubble of air. We take this further, proving the existence of a continuous curve of water waves from a laminar flow up to a touching wave for fixed non-zero gravity. LÄS MER

3. 7. An operator theoretic approach to the Riemann Hypothesis

   Master-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

   Författare :Ramon Arjan van de Scheur; [2023]
   Nyckelord :Riemann hypothesis; Prime number theorem; Prime number theorem for arithmetic progressions; operator theoretic equivalent; compact operator; prime-counting function; Chebyshev function; Laplace transform; Fourier transform; convolution operator; weak topology; strong topology; compact perturbation; Tauberian theorem; Poisson kernel; holomorphic; self-adjoint; spectrum; trace; Mathematics and Statistics;

   Sammanfattning : In 2023 an operator theoretic approach to the Prime Number Theorem was introduced by Olsen. In this thesis this approach is examined and applied to give a new, operator theoretic, proof of a different version of the Prime Number Theorem and of the Prime Number Theorem for arithmetic progressions.

4. 8. Första linjens chefers kunskaper om och förutsättningar för omställningen Nära vård

   Magister-uppsats, Högskolan i Borås/Akademin för vård, arbetsliv och välfärd

   Författare :Annette Olofsson; Jennie Hilbert; [2023]
   Nyckelord :Omställning Nära vård; Närhälsan; Primärvård; Första linjens chef; hållbart ledarskap; förändringsledning; förutsättningar chefer vården;

   Sammanfattning : Organisationen inom hälso- och sjukvården står inför stora utmaningar. Befolkningsstrukturen kommer att förändras till fler äldre och färre personer i arbetsför ålder. Det innebär att vården ska klara av ett ökat vårdbehov. Primärvården beskrivs vara navet i framtidens vårdorganisation. LÄS MER

5. 9. How to Rise from Ashes : A Comprehensive Guide to Finally Understand Canonical Quantization and Build Quantum Mechanics from Scratch

   L3-uppsats, Uppsala universitet/Materialteori; Uppsala universitet/Avdelningen för teoretisk filosofi

   Författare :Karl Herlin; [2022]
   Nyckelord :Quantum mechanics; History of quantum mechanics; Canonical Quantization; double-slit experiment; The Photoelectric Effect; Compton Scattering; Matter Waves; Bohr’s Atomic Model; Old Quantum Theory; Heisenberg-Born-Jordan Matrix Mechanics; Schrodinger’s Quantum Wave Mechanics; equations of motion;

   Sammanfattning : In this review essay, we account for the historical development of canonical quantization. By a detailed review of The Ultraviolet Catastrophe, The Photoelectric Effect, Compton Scattering, Matter Waves and Bohr's Atomic Model we learn about Old Quantum Theory. LÄS MER

7. 10. Correlation coefficient based feature screening : With applications to microarray data

   Magister-uppsats, Umeå universitet/Statistik

   Författare :Agnes Holma; [2022]
   Nyckelord :;

   Sammanfattning : Measuring dependency between variables is of great importance when performing statistical analysis and can for instance be used for feature screening. Therefore, it is interesting to find measures that can quantify the dependencies, even if the dependencies are complex. LÄS MER
