1. 1. Investigating the process parameters that influence the z-strength of liquid paperboard using data mining and machine learning

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

   Författare :Gustav Thaung Tolförs; [2021]
   Nyckelord :paperboard; liquid paperboard; z-strength; process parameters; machine learning; data mining;

   Sammanfattning : Parameters affecting the z-strength of liquid paperboard (LPB) has been analyzed and identifiedusing data mining and machine learning on 6 years of operational data from a multi-ply LPB mill, and control and stabilizing of them was proposed. Linear regression models were built for 9 articles with satisfactory results, and whose attributes were further analyzed as the most important parameters for the z-strength. LÄS MER

3. 2. Methods to create compressive stress in high strength steel components

   Kandidat-uppsats,

   Författare :Amir Abdin; Kaveh Feyzabi; Oskar Hellman; Henrietta Nordström; Dilman Rasa; Gustav Thaung Tolförs; Per-Olof Öqvist; [2018]
   Nyckelord :residual compressive stress; high strength steel; methods of inducing stress; analyzing stress;

   Sammanfattning : Residual compressive stresses can be used to increase the lifetime of parts under cyclic stress as they negate the applied tensile stresses that cause crack initiation and propagation in the material. The goal of this project was to investigate methods to induce stresses, their advantages and disadvantages as well as depth and magnitude of induced stresses, and also to find methods of analyzing the induced residual stresses.
