1. 1. Empirical Analysis of Dependence Structure Between Assets: A Study of the Impact of Infation on Dependence Between Stock Portfolios and Gold

   University essay from Göteborgs universitet/Graduate School

   Author : Tim Baldesten Pajunen; Filip Steussloff; [2023-06-29]
   Keywords : Infation;

   Abstract : In this paper, we study the impact of inflation on the dependence and volatilities of gold and stock portfolios constructed by Fama and French. To model the dependence structure, we propose a copula probability model. READ MORE

3. 2. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging

   University essay from KTH/Kemi

   Author : Arezu Sehati; [2023]
   Keywords : Coherent Diffraction Imaging; X-ray Free Electron Lasers; Refractive index; Core-shell nanoclusters; Rare-gas ionization; Koherent Diffraktionsavbildning; Röntgenfrielektronlaser; Brytningsindex; Core-shell-nanokluster; Ädelgasjonisering;

   Abstract : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. READ MORE

4. 3. Changes in Organization Design Produced by Covid-19 from a Path-Dependence Perspective : A Case Study of a Medical Manufacturing Company

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Carolina Artavia Muñoz; [2023]
   Keywords : Organization Design; Black Swan Events; Path Dependence Theory; Jay Galbraith s Star Model; Covid-19; Medical Manufacturing Industry.; Organisationsdesign; svarta svan-händelser; stigberoende; Jay Galbraits Star Model; Covid-19; medicinsk tillverkningsindustri.;

   Abstract : Covid-19 brought various challenges that the world that was not fully prepared to face since 2019. The pandemic came with both health and economic repercussions, and various organizations had to adapt their Organization Design to confront these new challenges posed by this Black Swan event.

5. 4. Superconducting gates for InP HEMTs

   University essay from KTH/Tillämpad fysik

   Author : Sebastian Alveteg; [2023]
   Keywords : Cryogenic electronics; HEMT; Superconductors; Applied Physics; Kryogenisk elektronik; HEMT; Supraledare; Tillämpad fysik;

   Abstract : The thesis examines the prospects of using the superconductor NbN as the gatemetal for an InP HEMT. A HEMT or High Electron Mobility Transistor is aheterostructure transistor engineered to reach very high electron mobility. InPHEMTs are used as cryogenic Low Noise Amplifiers (LNAs), which have increasedin demand as quantum computing is scaling up. READ MORE

6. 5. The tangled Warp of the Milky Way

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Viktor Hrannar Jónsson; [2023]
   Keywords : Galaxy: structure; Galaxy: kinematics and dynamics; Galaxy: disk; Galaxy: evolution; Physics and Astronomy;

   Abstract : Context: The Milky Way disc, like the discs of many other spiral galaxies, has been shown to be warped. The growing astrometric data set for stars produced by the Gaia mission allows for more detailed studies of the stellar disc's warp. READ MORE
