  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

    Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik; Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper

    Författare :Andreas Riedel; [2018]
    Nyckelord :Crease; Barrier coatings; Folding; Methodology; Cracks;

    Sammanfattning : 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. LÄS MER

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

    Kandidat-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

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

    Sammanfattning : 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. LÄS MER

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

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Uppsala universitet/Statistiska institutionen

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

    Sammanfattning : 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. LÄS MER

  7. 5. Investigation of Creases

    Master-uppsats, Lunds universitet/Innovation

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

    Sammanfattning : 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. LÄS MER
