  1. 1. Improving Machinery Safety : Modelling data to explain machine stops and developing a strategy on how to reduce them

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Kristina Leijonborg; Sandra Hammarsten; [2023]
    Keywords : ;

    Abstract : The purpose of this thesis is to examine how machinery safety at Stora Enso can be increased, with the goal of reducing the amount of machine stops and improving the operational safety within the Packaging Solutions division. To do this, data from the one of the machines at the Jönköping mill has been used for classification and time series modelling. READ MORE

  3. 2. Exploring Machine Learning Techniques for Short-Term Wind Power Forecasting of Multiple  Wind Parks

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Alexis Tubulekas; [2022]
    Keywords : ;

    Abstract : Wind power is a renewable energy source that is growing rapidly globally. A disadvantage of wind power is its uncertainty as the energy output can vary greatly, a consequence of the stochastic nature of the wind. Accurate forecasts of wind power production can mitigate the problem of uncertainty. READ MORE

  4. 3. Predicting House Prices on the Countryside using Boosted Decision Trees

    University essay from KTH/Matematisk statistik

    Author : War Revend; [2020]
    Keywords : Machine Learning; Predicting House Prices; Shrinkage Methods; Random Forest; Decision Tree; AdaBoost; Gradient Boosting; LightGBM; CatBoost; XGBoost; Maskininlärning; Förutseende av Huspriser; Krympningsmetoder; Random Forest; Beslutsträd; AdaBoost; Gradient Boosting; LightGBM; CatBoost; XGBoost;

    Abstract : This thesis intends to evaluate the feasibility of supervised learning models for predicting house prices on the countryside of South Sweden. It is essential for mortgage lenders to have accurate housing valuation algorithms and the current model offered by Booli is not accurate enough when evaluating residence prices on the countryside.

  5. 4. Nonlinear Finite Element Analysis of Shrinking Reinforced Concrete Slabs-on-ground

    University essay from KTH/Betongbyggnad

    Author : Shruthi Prakash; [2018]
    Keywords : Slabs-on-ground; Gradient shrinkage; Statical indeterminate structure; Vertical deflection and Cracking;

    Abstract : Concrete slabs-on-ground are commonly used in many types of industrial floors, warehouses, highways, parking lots and buildings. Cracks and deflection of slabs are undesired events caused by differential shrinkage, which limits the service life of the slabs. READ MORE

  6. 5. Cracking Assessment of Concrete Slab Frame Bridges Exposed to Thermally Induced Restraint Forces

    University essay from KTH/Betongbyggnad

    Author : Jonatan Ledin; Christensen Oskar; [2015]
    Keywords : Concrete slab frame bridges; Restraint forces; Thermal actions; Non linear FE analysis;

    Abstract : The usage of linear 3D FEA is widespread within the bridge design community, and although this tool provides substantial benefits in the design process, there are certain practical issues related to the application of this analysis tool. A situation in which such an issue prevails is when linear 3D FEA is used to analyze restraint forces due to thermal shrinkage or expansion in concrete slab frame bridges. READ MORE
