  1. 26. Validation of Quasi-Optical Antireflective Structures for Radar Lenses through Experimentation and Simulation

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Jeslin Preetha Sam Oliver; Simbarashe Tongai Makonese; [2023]
    Nyckelord :;

    Sammanfattning : This study focuses on designing, developing, and testing 3D-printed radar lenses with varying heights of Anti-Reflective (AR) structures (0.75mm, 1mm and 1.25mm). Radar lenses are essential to improve signal transmission and reception for radar systems. LÄS MER

  3. 27. Investigating changes in sustainability disclosure quality: A study on large European auto manufacturers

    Master-uppsats, Uppsala universitet/Företagsekonomiska institutionen

    Författare :Emil Aspnäs; Marcus Bergman; [2023]
    Nyckelord :Sustainability reporting; automotive industry; disclosure quality; legitimacy theory; strategic legitimacy; substantive and symbolic reporting;

    Sammanfattning : Large European auto manufacturers are responsible for being at the forefront when the industryis advancing towards a more sustainable practice. However, there is a problem with assessing companies´ sustainability performance because it can be camouflaged through low-quality reporting, preventing stakeholders from scrutinizing companies’ commitment to sustainable development.

  4. 28. Forecasting Stock Prices Using an Auto Regressive Exogenous model

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Måns Hjort; Lukas Andersson; [2023]
    Nyckelord :Bachelor thesis; Asset pricing; Quantitative finance; ARX model; OMX30; Finance; Stocks; Predictive models; Time series analysis; mathematical optimization theory; Gurobi Optimization Software;

    Sammanfattning : This project aimed to evaluate the effectiveness of the Auto Regressive Exogenous(ARX) model in forecasting stock prices and contribute to research on statisticalmodels in predicting stock prices. An ARX model is a type of linear regression modelused in time series analysis to forecast future values based on past values and externalinput signals. LÄS MER

  5. 29. Statistical analysis of LDMX data

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Författare :Noah Ritter; [2023]
    Nyckelord :LDMX; dark matter; light dark matter; statistics; hypothesis testing; ROOT; Physics and Astronomy;

    Sammanfattning : This thesis explores a statistical framework for analysing LDMX data. It uses pre-built functions in the ROOT framework to calculate likelihoods and confidence levels (CL). LÄS MER

  7. 30. Gender Imbalance and Educational Investments in China

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Jessica Johansson; Anna Johnsson; [2022]
    Nyckelord :Sex Ratio; Education; One Child Policy; Marriage; Signaling;

    Sammanfattning : An unintended consequence of the One Child Policy, introduced in 1979, has been the increasing sex ratio imbalance in China. This has resulted in millions of excess males, facing difficulties in finding a spouse. LÄS MER
