1. 11. The Effect of Mobile Financial Service on Migrant Worker’s Money Transfer Behavior in Bangladesh

   Master-uppsats, Göteborgs universitet/Graduate School

   Författare :Moshfika Haque; Julius Businge; [2023-06-01]
   Nyckelord :Money Transfer; MFS; Migrant Workers;

   Sammanfattning : Mobile financial service (MFS) works as a vital money transfer instrument for migrant workers in developing countries like Bangladesh, where the poor migrant workers had no access to financial institutions like banks before 2010. Before introducing MFS, migrant workers used to transfer money through friends/relatives, travel agents, agents/brokers, couriers, postal service etc. LÄS MER

3. 12. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

   Master-uppsats, Linköpings universitet/Reglerteknik

   Författare :Erik Axelsson; Sebastian Fagerstedt; [2023]
   Nyckelord :Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

   Sammanfattning : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. LÄS MER

4. 13. A European Material Kuznets Curve

   Kandidat-uppsats, Stockholms universitet/Nationalekonomiska institutionen

   Författare :Pyry Järvinen; Emil Fernström; [2023]
   Nyckelord :Material Kuznets Curve; Environmental Kuznets Curve; Economic Growth; Economics Development; Material Footprint; Emissions; Sustainable Growth; Decoupling; Europe;

   Sammanfattning : This bachelor thesis investigates the correlation between 28 European countries’material footprints (MF), as proxied by their Raw Material Consumption (RMC)per capita, and the environmental impact indicated by their carbon dioxide (CO2)emissions per capita, respectively, with their economic development, measured bytheir purchase power parity adjusted gross domestic product (GDP) per capita,during the period of 2008 to 2019. Specifically, through the theoretical frameworkof the Environmental Kuznets Curve (EKC) and by utilizing Fixed EffectsOrdinary Least Squares regression models as well as Pooled Mean Groupestimation, the thesis asks whether or not evidence can be found for the possibleexistence of an EKC, an inverted-U shaped relationship between environmentaldegradation and economic development, within this European context.

5. 14. The Effect of a Universal Primary Education Reform on Gender Attitudes in Uganda

   C-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Författare :Emma Bergman Karlsson; Klara Holmer; [2023]
   Nyckelord :Fuzzy Regression Discontinuity Design; Two-Stage Least Squares; Gender Attitudes; Universal Primary Education; Uganda;

   Sammanfattning : This thesis examines whether greater access to primary school education for girls and a decreased gender gap in primary school education affects gender attitudes, by studying a Universal Primary Education reform in Uganda that eliminated primary school fees. We conduct a Two-Stage Least Squares regression where we use exogenous variation in exposure to the reform as an instrumental variable to estimate the effect of educational attainment on gender attitudes.

7. 15. Randomized Diagonal Estimation

   Master-uppsats, KTH/Matematik (Avd.)

   Författare :Niclas Joshua Popp; [2023]
   Nyckelord :Diagonal estimation; randomized numerical linear algebra; low-rank approximation; matrix functions; Diagonalestimering; randomiserad numerisk linjär algebra; lågrankad approximation; matrisfunktioner;

   Sammanfattning : Implicit diagonal estimation is a long-standing problem that is concerned with approximating the diagonal of a matrix that can only be accessed through matrix-vector products. It is of interest in various fields of application, such as network science, material science and machine learning. LÄS MER
