  1. 1. Predicting catastrophic failure in barrier coated packaging board and paper after creasing and folding : Proposing a methodology to predict barrier failure after creasing and folding

    University essay from Karlstads universitet/Avdelningen för kemiteknik; Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper

    Author : Andreas Riedel; [2018]
    Keywords : Crease; Barrier coatings; Folding; Methodology; Cracks;

    Abstract : Different methods to predict barrier failure in packaging board or paper after converting were investigated. The approach was to compare substrates before and after creasing/folding by applying different barrier tests and to propose a methodology to predict failure in the barrier layer. READ MORE

  3. 2. Testing Direct Coupling Analysis on HP Model Proteins

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Mustafa Kadhim; [2018]
    Keywords : Direct Coupling Analysis HP model proteins; Physics and Astronomy;

    Abstract : Direct coupling analysis (DCA) models correlations in sets of related (homologous) protein sequences using a Potts-like spin model ansatz. From the couplings of the Potts model, derived by inverse statistical mechanics, residue-pair contacts in the 3D structure of the protein are predicted. READ MORE

  4. 3. Factors affecting the Relative Crease Strength of paperboard

    University essay from Lunds universitet/Hållfasthetslära

    Author : Oskar Smedman; [2017]
    Keywords : paperboard; paper mechanics; creasing; solid mechanics; design of experiments; simulation; Technology and Engineering;

    Abstract : Paperboard is frequently used as a base material in packages. There is folding involved in the conversion process, where a package is formed from a paperboard sheet. However, because direct folding causes undesirable effects such as wrinkles, it must first be creased. READ MORE

  5. 4. An empirical comparison of extreme value modelling procedures for the estimation of high quantiles

    University essay from Uppsala universitet/Statistiska institutionen

    Author : Alexander Engberg; [2016]
    Keywords : extreme value analysis; peaks over threshold; generalized Pareto distribution; mixture models; folding procedure;

    Abstract : The peaks over threshold (POT) method provides an attractive framework for estimating the risk of extreme events such as severe storms or large insurance claims. However, the conventional POT procedure, where the threshold excesses are modelled by a generalized Pareto distribution, suffers from small samples and subjective threshold selection. READ MORE

  6. 5. Investigation of Creases

    University essay from Lunds universitet/Innovation

    Author : David Alberius; Fredrik Gerstner; [2011]
    Keywords : Distortion; uncentering; displacement; creasing; RCS; Technology and Engineering;

    Abstract : One of the main concepts that made Tetra Pak a world leading company in producing packages for liquids, is the idea of folding paperboards. To get a good and precise fold it is necessary to crease the paper before the folding process takes part. By using creasing, the package can get more precise, stronger folds and can be produced at high speed. READ MORE
