  1. 1. Structure and developments in the solid wood value chain : dominant saw milling strategies and industrialized housing

    Författare :Tomas Nord; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : The study, using a combination of a qualitative case study and archival study approach, aims at describing and analyzing the development in the solid wood value chain i.e. sawn timber products, dominant Swedish saw milling strategies, and industrialized housing. LÄS MER

  3. 2. Supply chain optimization in the forest industry

    Författare :Helene Gunnarsson Lidestam; Mikael Rönnqvist; Jan Lundgren; Eldon Gunn; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supply chain; logistics; forestry; optimization; modelling; transportation; mixed integer programming models; försörjningskedjor; logistik; optimering; modellering; transportplanering; blandade heltalsproblem; skogsindustrin; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : The scope of this thesis is modelling and solving large-scale planning problems in the supply chain within the forest industry. Five research papers are included, the first three of which focus on the modelling, and the last two on the solution methods. LÄS MER

  4. 3. Skogsarbetarna och motorsågen : en studie av arbetsliv och teknisk förändring

    Författare :Jonny Hjelm; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Forestry; forest worker; chain saw; mechanization; rationalization; labour history; working life; technical change; cutting operation;

    Sammanfattning : This study deals with how workers actively introduced a new technique to their own labour process. More specifically, it is concerned with how Swedish forest workers during the 1950s gradually replaced the manual one-man crosscut saw with the motor-driven saw. LÄS MER

  7. 5. Effects of the environment on quantum systems: decoherence, bound states and high impedance in superconducting circuits

    Författare :Marco Scigliuzzo; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TLS; atom photon bound state; circuit QED; quantum thermodynamics; two-level systems; surface acoustic wave; high impedance; superconducting circuits; SAW;

    Sammanfattning : Superconducting circuits in the quantum regime represent a viable platform for microwave quantum optics, quantum simulations and quantum computing. In the last two decades, a large effort brought this architecture from an academic curiosity to concrete technology. LÄS MER
