  1. 1. Baggy paper webs : Effect of uneven moisture and grammage profiles in different process steps

    Författare :Cecilia Land; Lennart Stolpe; Kaarlo Niskanen; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bagginess; drying; calendering; grammage; moisture content; paper; profile; reels; softwood kraft pulp; storage; strain; tension; web; Chemical Engineering; Kemiteknik;

    Sammanfattning : One of the problems encountered in paper converting is caused by the occurrence of "baggy webs", which essentially is when the tension profile of the paper web is uneven. In an area with low tension the paper is longer, which results in bagginess. LÄS MER

  3. 2. Application of operations research in operative planning in the forest industry

    Författare :Patrik Flisberg; Mikael Rönnqvist; Jens Clausen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; operative planning; routing; forestry; modelling; Decision Support System; optimization; OR in practice; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : The focus of this thesis is the use of Operations Research for pplications in the forest industry. Optimization models and methods have been developed for problems in the forest supply chain and they have been integrated in decision support systems. The problems considered in this thesis are operative with a planning horizon of less than a month. LÄS MER

  4. 3. Evaluation of volatile organic compounds related to board based packaging by use of instrumental and sensory analysis

    Författare :Gunnar Forsgren; Fredrik Winquist; Ola Karlsson; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The main topic of the thesis is characterisation and evaluation of volatile organic compounds emitted by packaging materials based on paperboard products. The properties and concentration of these compounds are critical to how well these materials perform when applied as a main component of food packaging. LÄS MER

  5. 4. Contribution to multiagent planning for active information gathering

    Författare :Jennifer Renoux; France Université de CaenCaen GREYC; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Decentralized planning; Multiagent systems; Information relevence; Planification décentralisée; Système multiagents; Pertinence de l’information;

    Sammanfattning : In this thesis, we address the problem of performing event exploration. We define event exploration as the process of exploring a topologically known environment to gather information about dynamic events in this environment. LÄS MER

  7. 5. Wind-induced vibrations in tall timber buildings : Design standards, experimental and numerical modal analyses
