1. 1. District heating comes to town : The social shaping of an energy system

   Författare :Jane Summerton; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; district heating; municipal technology; energy system; pipeline; large t<:chnical system; actor network; multiorganization; grid; grid-based energy system; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : This thesis deals with the introduction of district heating in an "ordinary" Swedish town: Mjölby. The process was initiated in 1974 and the decision to build was taken in 1979. In the following years pipelines were laid down and the system was gradually built. In 1987, a permanent heat plant was ready to assume operation. LÄS MER

3. 2. Unfolding the formative phase of gasified biomass in the European Union: The role of system builders in realising the potential of second-generation transportation fuels from biomass

   Författare :Hans Hellsmark; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; technical change; second-generation transportation fuels; technology policy.; technological innovation systems; biomass gasification; system builders;

   Sammanfattning : In an era of climate change, the process of and time frame for fostering new industries with the capacity of being innovative and able to diffuse a wide range of renewable energy technologies on a large scale has become a pressing issue. In the midst of the creation of such industries are the system builders―without such actors, new technologies and industries would not emerge. LÄS MER

4. 3. Emerging networks of power: Exploring sociotechnical pathways towards future electricity systems based on renewable energy technologies

   Författare :Kristina Hojcková; Chalmers tekniska högskola; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; entrepreneurs; context; sociotechnical systems perspective; Technological Innovation System; Multilevel Perspective; electricity system; transition pathways; incumbents; renewable energy; energy users;

   Sammanfattning : In the effort to fight climate change, electricity systems around the world are undergoing a transition from fossil-fuelled to renewable energy-based production of electricity. The transition can, however, be attained in several radically different ways, ranging from global or continental super-grids, via local smart-grids, to self-sufficient off-grid communities and households of electricity prosumers.

5. 4. Development of a PKM control system by design, modelling, simulation and integration

   Författare :Qi Huang; KTH; []
   Nyckelord :Control System Design; PKM machines; Kinematic transformation; Dynamic modelling; Motion control simulation;

   Sammanfattning : PKM (ParallelKinematicMechanism) machines have received increasing interestfrom industries. Nevertheless, they didn't turn out goodresults in control performances as desired. One of the reasonsis the unsuitability of the available control systems for theparallel mechanisms.This thesis presents a process to develop a PKM controlsystem. LÄS MER

7. 5. Nationell kraft och lokal motkraft : En diskursanalys av konflikten kring SwePol Link

   Författare :Maria Alm; Johan Hedrén; Lars Ingelstam; Eva Sandstedt; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; siting conflicts; sociotechnical systems; discourse analysis; space; place; practices; inclusion; exclusion; patterns of arguments; lokaliseringskonflikter; sociotekniska system; diskursanalys; plats; rum; praktiker; inneslutningar och utestängningar; mönster och utsagor; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : Facility siting conflicts are increasing in our society. This is a study of a HVDC-link between Blekinge, Sweden and Slupsk, Poland called The SwePol Link. This link has transferred electricity between the two electricity systems since the year 2000 and the decision making process can be described as a struggle between conflicting interests. LÄS MER
