1. 1. Investigating Non-Linear Exchange Rate Pass-Through in Sweden: Estimates from a Logistic Smooth Transition Vector Autoregressive Model

   D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Författare :Gabriella Linderoth; Malte Meuller; [2024]
   Nyckelord :Exchange Rate Pass-Through; Sweden; Inflation; Non-Linear; Logistic Smooth Transition Vector Autoregressive;

   Sammanfattning : This paper provides novel estimations of a non-linear exchange rate pass-through dependent on inflation for Sweden using a logistic smooth transition vector autoregressive model. The model enables smooth transitions between high and low inflation regimes, mirroring the dynamics of the economy and capturing regime-specific effects. LÄS MER

3. 2. Robust Portfolio Optimization with Correlation Penalties

   Master-uppsats, KTH/Matematisk statistik

   Författare :Pelle Nydahl; [2023]
   Nyckelord :Portfolio Optimization; Portfolio Allocation; Robust Optimization; Correlation; Risk Factor Model; EMA Filtering; Weighted Linear Regression; Portföljoptimering; Portföljallokering; Robust optimering; Korrelation; Riskfaktor-modell; EMA-filtrering; Viktad linjär regression;

   Sammanfattning : Robust portfolio optimization models attempt to address the standard optimization method's high sensitivity to noise in the parameter estimates, by taking an investor's uncertainty about the estimates into account when finding an optimal portfolio. In this thesis, we study robust variations of an extension of the mean-variance problem, where an additional term penalizing the portfolio's correlation with an exogenous return sequence is included in the objective.

4. 3. Electron-skyrmion systems, in and out of equilibrium, and isolated or contacted to reservoirs

   Magister-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

   Författare :Emil Adam Jonatan Östberg; [2023]
   Nyckelord :skyrmion; skyrmions; NEGF; freen s function; quantum transport; non-equlibrium; topology; topological charge; skyrmionics; current induced; open system; Physics and Astronomy;

   Sammanfattning : A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. LÄS MER

5. 4. More Fish, more Mahasoa? A Quantitative Analysis of Food Security & Poverty Reduction in Rural Small-scale Aquaculture in Madagascar

   Master-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

   Författare :Gianna Laura Angermayr; [2023]
   Nyckelord :Madagascar; Small-scale Aquaculture; Pond Aquaculture; Integrated Rice-Fish Farming; Community Well- being; Poverty Reduction; Food Security.; Business and Economics;

   Sammanfattning : The role of food-producing sectors such as agriculture and aquaculture in the development process is debated and while some consider industrial production to be the answer, others suggest that small-scale production can also make contributions to poverty reduction and food security. This thesis aims to shed light on these relationships by performing quantitative analyses of the small-scale freshwater aquaculture sector in six regions of Madagascar. LÄS MER

7. 5. Konstruktion av extern linjärgivare för kranutskjut : Utveckling och utvärdering av sensorteknik för att förbättra positionsangivning för kranutskjut

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

   Författare :Dekran Zakar; Tobias Burström; [2023]
   Nyckelord :Design; extern linjärgivare; kranutskjut; produktutveckling; sensor; vinkelgivare;

   Sammanfattning : In this work, a study, design and development process for an external linear sensor for one of Cranabs forestry machines has been carried out. The purpose of the degree project was to investigate and develop various design proposals for alternatives to linear sensors in crane extensions that are not built into a hydraulic cylinder. LÄS MER
