1. Improving Machinery Safety : Modelling data to explain machine stops and developing a strategy on how to reduce them
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för matematik och matematisk statistikSammanfattning : 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. LÄS MER
2. Exploring Machine Learning Techniques for Short-Term Wind Power Forecasting of Multiple Wind Parks
Master-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : 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. LÄS MER
3. Predicting House Prices on the Countryside using Boosted Decision Trees
Master-uppsats, KTH/Matematisk statistikSammanfattning : 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.

4. Sprickbildning i platta på mark orsakad av oliksidig uttorkning : En finit elementanalys
M1-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknikSammanfattning : Betong är idag ett av de mest använda byggnadsmaterialen och konstruktionen platta på mark en av de vanligaste grundläggningsmetoderna. Problem med sprickbildning i konstruktionen är vanligt förekommande och orsakas troligen av oliksidig uttorkning. Vid uttorkning krymper betong beroende på hur fuktig omgivningen är. LÄS MER
5. Nonlinear Finite Element Analysis of Shrinking Reinforced Concrete Slabs-on-ground
Master-uppsats, KTH/BetongbyggnadSammanfattning : 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. LÄS MER
