1. 1. Machine Learning for Pulse Shape Analysis of Heavy Ions

   Magister-uppsats, Uppsala universitet/Tillämpad kärnfysik

   Författare :Steven Hendrik Bijl; [2023]
   Nyckelord :Heavy Ions; Machine Learning;

   Sammanfattning : Most of the Generation IV nuclear reactors designs are intended to operate with a fast neutron spectrum. This necessitates further investigation into nuclear fuel behaviour because fast neutrons yield a higher neutron multiplicity with fission fragments, significantly impacting the criticality assessment of these reactors.

3. 2. Supersymmetry in Quantum Mechanics

   Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Författare :Simon Kuberski; [2014]
   Nyckelord :supersymmetric quantum mechanics; partner potentials; quantum mechanics; partner Hamiltonian; shape invariant potential; shape invariance; Morse potential; Physics and Astronomy;

   Sammanfattning : This thesis gives an introduction to the basic formalism of one-dimensional supersymmetric quantum mechanics. The factorization of a Hamiltonian is used to create a supersymmetric partner Hamiltonian. LÄS MER

4. 3. On the Invariance of Size Distribution of Establishments

   Master-uppsats, IHH, Nationalekonomi

   Författare :Polina Kamanina; [2012]
   Nyckelord :establishment size distribution; invariance; Pareto distribution; regional structure;

   Sammanfattning : The thesis examines the establishment size distribution over time and across groups of regions, using data on Swedish establishments during period 1994-2009. The size distribution of establishments is highly skewed and approximates the Pareto distribution. The shape of size distribution is invariant over time and across groups of regions. LÄS MER
