  1. 1. Anomaly detection with machine learning methods at Forsmark

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Simon Sjögren; [2023]
    Keywords : machine learning; nuclear power; nuclear power plant; anomaly detection; anomaly; data processing; data-driven; autoencoder; maskininlärning; kärnkraft; kärnkraftverk; Forsmark; anomalidetektion; anomali; databehandling;

    Abstract : Nuclear power plants are inherently complex systems. While the technology has been used to generate electrical power for many decades, process monitoring continuously evolves. There is always room for improvement in terms of maximizing the availability by reducing the risks of problems and errors. READ MORE

  2. 2. The derivation of first- and second-order backpropagation methods for fully-connected and convolutional neural networks

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematikcentrum

    Author : Simon Sjögren; [2021]
    Keywords : Mathematics and Statistics;

    Abstract : We introduce rigorous theory for deriving first and second order backpropagation methods for Deep Neural Networks (DNN) whilst satisfying existing theory in DNN optimization. We begin by formally defining a neural network with its respective components and state the first and second order chain rule with respect to its partial derivatives. READ MORE

  3. 3. A study on CEO organizational identification, the propensity to be acquired, and bid premiums

    University essay from Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Author : Oscar Kock; Simon Sjögren; [2020]
    Keywords : Organizational identification; M A; Agency problems; Corporate governance; Golden parachutes;

    Abstract : We examine whether the propensity to be acquired is lower for companies with CEOs who identify strongly with their organization compared to those that do not, while further distinguishing if this effect is amplified by the CEO also being a board member. Additionally, the study examines if the bid premium accepted is higher for CEOs with high organizational identification relative to other CEOs. READ MORE

  4. 4. Ett rumsligt experiment i sten, vatten och metall

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Birger Gustafsson; Jonas Sjögren; [2019]
    Keywords : sten; vatten; metall; god plats; gestaltning; hårdgjort;

    Abstract : Detta examensarbete undersöker en experimentell design inom landskapsarkitektur med begränsningen att enbart använda sten, vatten och metall. Genom att analysera och djupdyka ner i personliga platser från författarnas uppväxt diskuteras möjligheterna för att skapa ett experimentellt offentligt rum som kan uppfattas som en “god plats” vid Hamnplan, Uppsala.

  5. 5. Designing a deep-learning network for traffic density and volume prediction

    University essay from Lunds universitet/Matematik LTH

    Author : Simon Sjögren; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : It is relatively easy to know the day to day traffic flow on a highway without taking into account on which lane the cars are driving on. It is more difficult to understand how traffic over time evolves while looking at the lanes, or more specifically, by looking at traffic volume on the specific lanes on a highway, can we have a good guess for where the vehicles should be on a different lane of the same highway in the future? And could it also be possible to predict future congestion in one juncture by looking at incoming traffic from the past at another or multiple junctions somewhere else? This project serves as a precursor for possible future projects by looking at how traffic volume on a given road with 5 lanes evolves over time. READ MORE
