The industry is also known to be capital intensive, highly dependent on infrastructural developments and requires thorough planning of operations. READ MORE

  4. 12. Surface characterization methods for quality assessment of polyethylene-coated paperboard

    Author : Javier Mauricio Brugés; Jan Lundgren; Mattias Andersson; Mikael Sjödahl; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polarization; surface characterization; Stokes polarimeter; polyethylene coating; paperboard;

    Abstract : In manufacturing processes, the quality of a product often depends on its surface, and careful control of surface properties is critical to meet customer requirements. A thin layer of polyethylene (PE) is applied to paperboard to increase barrier functionality and high optical quality of the product. READ MORE

  5. 13. Designing Urban Road Congestion Charging Systems : Models and Heuristic Solution Approaches

    Author : Joakim Ekström; Jan Lundgren; Anders Karlström; Linköpings universitet; []
    Keywords : transport modeling; congestion pricing; network design; bi-level optimization; toll locations; traffic assignment; user equilibrium; collection cost; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The question of how to design a congestion pricing scheme is difficult to answer and involves a number of complex decisions. This thesis is devoted to the quantitative parts of designing a congestion pricing scheme with link tolls in an urban car traffic network. READ MORE

  6. 14. Optimization Approaches for Design of Congestion Pricing Schemes

    Author : Joakim Ekström; Jan Lundgren; Richard Connors; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In recent years, there has been a growing interest in congestion pricing as a tool for solving traffic congestion problems in urban areas. However, the transportation system is complex and to design a congestion pricing scheme, i.e. to decide where and how much to charge the road users, is not trivial. READ MORE
