  1. 1. Material Flows Incurred by Activities at Project Sites

    Author : Nina Modig; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temporary organization; project site; project; supply network; logistics; material flows;

    Abstract : The execution of numerous projects is dependent on the movement of large quantities of heterogeneous material to and from project sites. This has to be done in a timely manner to successfully produce desired outputs, e.g. buildings, concerts, peacekeeping operations and sport events. READ MORE

  2. 2. Network Disruption and Turbulence in Fibre Suspensions

    Author : Sven Andersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transition; friction; refractive index matching; Laser Doppler Anemometry LDA ; boundary-layer; Computational Fluid Dynamics CFD ; medium consistency MC ; network strength; fluidisation; pulp; suspension; fibres;

    Abstract : The production of paper pulp involves the handling of large quantities of fibre suspensions. Today's call for energy efficiency and environmentally sound processes has led to the development of MC (Medium Consistency) technology. READ MORE

  3. 3. On the use of traffic flows for improved transportation systems : Mathematical modeling and applications

    Author : Henrik Fredriksson; Mattias Dahl; Johan Holmgren; Benny Lövström; Joakim Ekström; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mathematical modeling; Transportation systems; Link flows; Mathematics and applications; Matematik med tillämpningar;

    Abstract : This thesis concerns the mathematical modeling of transportation systems for improved decision support and analysis of transportation-related problems. The main purpose of this thesis is to develop and evaluate models and methods that exploit link flows. READ MORE

  4. 4. Narrowing the gap between network models and real complex systems

    Author : Alcides Viamontes Esquivel; Martin Rosvall; Joachim Mathiesen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; complex systems; network science; community detection; model selection; signficance analysis; ergodicity; fysik; Physics;

    Abstract : Simple network models that focus only on graph topology or, at best, basic interactions are often insufficient to capture all the aspects of a dynamic complex system. In this thesis, I explore those limitations, and some concrete methods of resolving them. READ MORE

  5. 5. On Robust Distributed Control of Transportation Networks

    Author : Gustav Nilsson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Signal Control; Distributed Control; Routing; Transportation Networks; Network Flows;

    Abstract : With the ever-growing traffic demands, the transportation networks are getting more and more congested. While expanding these networks with more roads is both costly and in many cities not even feasible, the rapid development of new sensing and communication techniques has made it possible to perform control of transportation networks in real-time.
