  1. 1. Inclusion of differential pricing in congestion charging scheme: The case of Stockholm and Curitiba

    University essay from KTH/Transportplanering

    Author : Joaquin Franco; [2023]
    Keywords : ;

    Abstract : Among transport demand management (TDM) strategies, congestion pricing has been one of the most widely applied, but at the same time one of the most criticised. The reason is that this measure is considered regressive, exclusionary, and inequitable, since having a flat rate ignores people's ability to pay, i.e. READ MORE

  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. Efficient FE Modeling of Large Casted Parts

    University essay from KTH/Maskinkonstruktion

    Author : Lalitha Swetha Amirapu; Haswanth Yalamanchili; [2023]
    Keywords : FE modeling; Large casted parts; Meshing techniques; Mid-surface modeling; FE-modellering; Stora gjutna delar; Meshing-tekniker; Mid-Surface modellering;

    Abstract : The design and analysis of large casted parts present significant challenges due to their complex geometry. Finite Element (FE) modeling is a vital tool for understanding the performance of casted components. However, the computational requirements associated with these parts often lead to excessive processing times and resource utilization. READ MORE

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Guillaume Larrat; [2023]
    Keywords : Open-Circuit-Voltage OCV Hysteresis - Voltage relaxation - Galvanostatic Intermittent Titration Technique GITT - Hysteresis modelling; Öppenkretsspännings OCV hysteres - Spänningsrelaxation - Galvanostatisk intermittent titreringsteknik GITT - Hysteresmodellering;

    Abstract : In a context of an expected increasing use of Lithium-ion batteries in the transportation sector, Volvo AB is developing its own solutions for large electric vehicles. It is then beneficial to reduce the costs, the energy demand and the raw materials demand by improving the battery systems’ performances. READ MORE

  6. 5. A Comparative Analysis of Database Management Systems for Time Series Data

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tove Verner-Carlsson; Valerio Lomanto; [2023]
    Keywords : Database Management Systems; PostgreSQL; TimescaleDB; MongoDB; Time Series; Database Comparison; Performance Analysis; Databashanteringssystem; PostgreSQL; TimescaleDB; MongoDB; Tidsserier; Databasjämförelse; Prestandaanalys;

    Abstract : Time series data refers to data recorded over time, often periodically, and can rapidly accumulate into vast quantities. To effectively present, analyse, or conduct research on such data it must be stored in an accessible manner. For convenient storage, database management systems (DBMSs) are employed. READ MORE
