  1. 26. Sodium Model for Production Planning in a Paper Mill

    University essay from Umeå universitet/Institutionen för fysik

    Author : Isak Lindfors; [2022]
    Keywords : Paper Mill; Production Planning; Modelling; Liquor; Sodium;

    Abstract : In today’s pulp and paper industry the Kraft process is the most common method for pulp production. This method uses sodium based chemicals (white liquor) in the cooking process to remove lignin from the wood chips and create pulp. READ MORE

  3. 27. Non-Destructive Biomass and Relative Growth Rate Estimation in Aeroponic Agriculture using Machine Learning

    University essay from Lunds universitet/Matematik LTH

    Author : Oskar Åström; [2022]
    Keywords : Machine Learning; Image Analysis; Aeroponics; Hydroculture; Relative Growth Rate; Multi-variate Regression; Neural Network; ResNet; Plant Growth; Plant Physiology; Technology and Engineering;

    Abstract : Optimising plant growth in a controlled climate requires good measurements of both biomass (measured in grams) and relative growth rate (measured in grams of growth per day and gram of plant). In order to do this efficiently and continuously on an individual level during plant development, this has to be done non-destructively and without frequent and labor intensive weighing of plant biomass.

  4. 28. Improving Aircraft Fuel Consumption Prediction through Ensemble Learning

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Hanlin Gongzhang; [2022]
    Keywords : Aeronautics; Commercial Aircraft; Aircraft fuel consumption; Flight data; Aircraft performance model; Aircraft fuel consumption modelling; Weighted average ensemble; Machine learning; Flygteknik; Kommersiellt flyg; Flygplanens bränsleförbrukning; Flygdata; Flygplanens prestandamodell; Flygplans förbrukningsmodellering; Viktad medelvärdesensemble; Maskininlärning;

    Abstract : Performance models provided by aircraft manufacturers are used by aircraft operators to perform flight path simulations aiming to reduce aircraft fuel consumption. However, performance models are generic and does not account for the performance deviations of each aircraft individual. READ MORE

  5. 29. A Physics-Informed Deep Learning Framework for Solving Inverse Problems in Epidemiology

    University essay from KTH/Optimeringslära och systemteori

    Author : Magnus Tronstad; [2022]
    Keywords : ;

    Abstract : This thesis develops and evaluates a physics-informed neural network (PINN) modelling framework for solving inverse problems in epidemiology. The PINN works by modifying the standard mean squared error loss function of the neural network, by adding a term penalizing deviations from a given compartmental model's system of ordinary differential equations.

  6. 30. Estimation of satellite orbits using ground based radar concept

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jonas Gabrielsson; [2021]
    Keywords : ;

    Abstract : Today an abundance of objects are circulating in earth captured orbit. Monitoring these objects is of national security interest. One way to map any object in orbit is with their Keplerian elements. A method for estimating the Keplerian elements of a satellite orbit simulating a ground based radar station has been investigated.
