   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; Internet industry; economic geography; agglomeration economies; social network relations; information flows; Stockholm; Sweden; Kulturgeografi; Human geography; Kulturgeografi;

   Sammanfattning : This thesis deals with questions concerning spatial agglomeration of economic activities. The object of study is the Internet industry in central Stockholm. LÄS MER

3. 2. Material Flows Incurred by Activities at Project Sites

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

   Sammanfattning : 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. LÄS MER

4. 3. Network Disruption and Turbulence in Fibre Suspensions

   Författare :Sven Andersson; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

7. 5. Narrowing the gap between network models and real complex systems

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

   Sammanfattning : 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. LÄS MER
