1. 1. Deep Neural Networks as SurrogateModels for Fuel Performance Codes

   Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik

   Författare :Wenhan Zhou; [2023]
   Nyckelord :Transuranus; AI; Nuclear Fuel Rods;

   Sammanfattning : The core component of a nuclear power plant is the reactor and the fuel rods that supply it with fission fuel. Efficient and safe energy extraction is thus highly dependent on the reactor design and the conditions of the fuel rods. To anticipate high-quality operation and potential risks in advance, one must perform simulations on the fuel rods. LÄS MER

3. 2. Fractional Cointegration and Price Discovery in FX Markets

   D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Författare :Johan Faxner; [2023]
   Nyckelord :exchange rates; price discovery; fractional cointegration; market microstructure; covered interest rate parity;

   Sammanfattning : I employ bivariate fractionally cointegrated vector autoregressive models to analyze price discovery on the EUR/GBP market. Using daily spot rates between 2010 and 2022 along with corresponding one-month and three-month forward rates, I extract parameter estimates for pairwise long-run relationships, each pair containing a spot and a forward.

4. 3. Hemlösa i pressen : En kritisk diskursanalys av massmedias framställningar av den hemlösa individen under en 25 års period

   Master-uppsats,

   Författare :Kristofer Nilsson; [2019]
   Nyckelord :homeless; homelessness; critical discourse analysis; mass media; social work; hemlösa; hemlöshet; kritisk diskursanalys; massmedia; socialt arbete;

   Sammanfattning : Denna studie syftar till att undersöka vilka diskurser som framträder i massmedia om hemlösa, hur och var de framträder samt om det skett några förändringar gällande detta under de senaste 25 åren (1993–2018) och, i så fall, hur dessa förändringar sett ut. För att besvara detta syfte har 55 artiklar som publicerats i Dagens Nyheter under perioderna 1993-07-01–1993-12-31, 2005-07-01–2005-12-31 och 2018-07-01–2018-12-31 analyserats med hjälp av kritisk diskursanalys.

5. 4. On the use of integer and fractional flexible Fourier form Dickey-Fuller unit root tests

   Master-uppsats, Lunds universitet/Nationalekonomiska institutionen

   Författare :Marcus Nordström; [2018]
   Nyckelord :Fractional frequency flexible Fourier form; Unit root test; Structural break; Smooth break; Nonlinear trend; Business and Economics;

   Sammanfattning : In this paper we propose the use of a new set of conservative critical values for the flexible Fourier form Dickey-Fuller unit root test when the Fourier frequency is estimated. We consider both the integer frequency and the fractional frequency version of the test and investigate their size and power properties. LÄS MER

7. 5. Counting Class Numbers

   Master-uppsats, KTH/Matematik (Avd.)

   Författare :Tobias Magnusson; [2018]
   Nyckelord :;

   Sammanfattning : The following thesis contains an extensive account of the theory of class groups. First the form class group is introduced through equivalence classes of certain integral binary quadratic forms with a given discriminant. The sets of classes is then turned into a group through an operation referred to as "composition''. LÄS MER
