  1. 21. Neural Cleaning of Swedish Textual Data : Using BERT-based methods for Token Classification of Running and Non-Running Text

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

    Author : Andreas Ericsson; [2023]
    Keywords : Natural Language Processing; Text Cleaning; Transformers; BERT; Token Classification; Deep Learning; Språkteknologi; Textrensning; Transformers; BERT; Token-klassificering; Djupinlärning;

    Abstract : Modern natural language processing methods requires big textual datasets to function well. A common method is to scrape the internet to acquire the needed data. This does, however, come with the issue that some of the data may be unwanted – for instance, spam websites. READ MORE

  3. 22. Investigating the Estimation of the infection rate and the fraction of infections leading to death in epidemiological simulation

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Jakob Gölén; [2023]
    Keywords : Epidemics; Compartmental Models; Parameter Inference; Synthetic Bootstrap; Infection Rate;

    Abstract : The main goal of this project is to investigate the behaviors of parameters used when modeling an epidemic. A stochastic SIHDRe model is used to simulate how an epidemic evolves over time. READ MORE

  4. 23. Automated Foreign Object Detection on Conveyor Belts

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

    Author : Kim Sundelius; [2023]
    Keywords : Machine Learning; Deep Learning; Object Detection; Anomaly Detection;

    Abstract : Ore is transported using belt conveyor systems. The transported ore has various anomalous objects that must be removed to prevent damage to the system. Currently anomalies are detected manually using humans. This leads to increased costs of wages and damage to the system overmissed anomalies. READ MORE

  6. 25. Adjoint optimization of a liquid-cooled heat sink

    University essay from KTH/Teknisk mekanik

    Author : Roven Pinto; [2023]
    Keywords : Adjoint method; topology optimization; porosity; OpenFOAM;

    Abstract : Improving the design of flow channels in a liquid-cooled heat sink is critical for boosting the capabilities of electronic components as well as reducing energy usage by the pump. This work explores the use of topology optimization to minimize the pressure difference across a heat sink and consequently, the energy used to supply the liquid. READ MORE
