  1. 1. Oscillations in a complex sunspot: From theory to data

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Femke Kranenbarg; [2024]
    Keywords : ;

    Abstract : Sunspot oscillations, intricate three-dimensional wave-like motions in the solar atmosphere, result from the complex interplay between plasma and magnetic fields. This study delves into the behaviour of these oscillations, exploring their simultaneous excitation and evaluating their impact on solar phenomena like coronal heating, energy transport, and solar flares.

  3. 2. Using Social Media and Personality Predictions to Anticipate Startup Success

    University essay from Lunds universitet/Matematisk statistik

    Author : Daniel Stenson; [2023]
    Keywords : Machine Learning; Startup Success Predictions; Founder Personalities; Natural Language Processing; Social Media Analysis; Big 5 Personality Framework; Feed-forward Neural Network; XGBoost.; Mathematics and Statistics;

    Abstract : This thesis explores the potential of integrating predicted founder personalities, based on the Big 5 Personality Framework, into Machine Learning (ML) models to enhance the accuracy of early-stage startup success predictions. Leveraging Natural Language Processing (NLP) techniques, we extracted personality insights from founders' tweets, focusing on US startups funded between 2013 and 2015. READ MORE

  4. 3. Finding the Seeds of Supermassive Black Holes: The Direct Collapse Black Hole Scenario

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Weihui Li; [2023]
    Keywords : ;

    Abstract : The origin of supermassive black holes (SMBHs,∼ 10^9M⊙) in the first billion years of cosmic history remains a mystery. Direct Collapse Black Holes (DCBHs,∼ 10^4M⊙) are considered one of the most promising hypotheses for the progenitor of SMBHs, as they are believed to provide a favorable starting point as massive seeds for SMBH formation.

  5. 4. Numerical Study on Aerodynamic Drag Reduction on a Rear Wing of a Formula Student Car

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Mahim Ahsan; [2021]
    Keywords : ;

    Abstract : The importance of aerodynamics in racing has increased substantially over the past decades. Racing vehicles utilize different aerodynamic devices, to redirect the airflow around the vehicle in a beneficial way. The increase in downforce using an aerodynamic wing package increases drag force. READ MORE

  6. 5. Solar access potential affected by urban planning and building design – A parametric study in the urban context

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Yuncong Li; Yiting Tian; [2020]
    Keywords : Daylight; urban planning; solar access potential; sun hours; vertical sky component; vertical daylight illuminance; solar irradiation; parametric analysis; Berlin; Copenhagen; Hong Kong; Arts and Architecture; Technology and Engineering;

    Abstract : In the initial stage of planning, considering the solar impact of urban layout on the building can effectively avoid some irreversible design issues, improve the indoor environment, and reduce energy demand. The typical architectural models of three representative cities (Copenhagen, Berlin and Hong Kong) were selected as the analysis cases in this study. READ MORE
