1. 16. Renewable Energy in Energy-Efficient, Low-Pollution Systems

   Författare :Bengt Johansson; Miljö- och energisystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogen; ethanol; methanol; rape methyl ester; biomass; renewable energy; cogeneration; energy efficiency; scenarios; air pollution; carbon dioxide; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : Energy use accounts for the dominating fraction of total sulphur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) and carbon dioxide (CO2) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. The thesis is divided in two parts. LÄS MER

3. 17. Investigation into sustainable energy systems in Nordic municipalities

   Författare :Robert Fischer; Andrea Toffolo; Erik Elfgren; Danica Djuric Ilic; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable energy sources; Nordic municipalities; municipal energy system; electrified transport; biofuels; multi-objective optimization; EnergyPLAN; Energiteknik; Energy Engineering;

   Sammanfattning : Municipal energy systems in Nordic environments face multiple challenges: the cold climate, large-scale industries, a high share of electric heating and long distances drive energy consumption. While actions on the demand side minimize energy use, decarbonization efforts in mining, industries, the heating and the transport sector can increase the consumption of electricity and biofuels.

4. 18. Towards Systemic Governance of Critical Infrastructure Protection : State and Relevance of a Swedish Case

   Författare :Christine Große; Aron Larsson; Olof Björkqvist; Pär M. Olausson; Alexander Fekete; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systemic Thinking; Infrastructure; Governance; Critical Infrastructure Protection; Complex Systems; Soft Operations Research; design-oriented Information Systems Research; Integrative System Analysis; KISA; STYREL; Multi-level Planning; Adaption; Emergence; Entropy; Systemic Governance;

   Sammanfattning : The protection of infrastructure that is critical to society’s functionality, survival and progression has gained significance for both national security and research because of its large-scale and interdependent nature. Critical infrastructure can be viewed as a complex, socio-technical system-of-systems that imposes extensive requirements on governance efforts to foster critical infrastructure protection (CIP), regardless of whether it involves public organisations, private organisations or both.

5. 19. Design Space Exploration of Wireless Multihop Networks

   Författare :Urban Bilstrup; Bertil Svensson; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless multihop networks; wireless sensor networks; Ad hoc networks; Design space; Wireless embedded networks; Packet radio networks;

   Sammanfattning : This thesis explores the feasible design space of wireless multihop networks and identifies fundamental design parameters. In the process of exploring it is important to ignore all details and instead take a holistic view. LÄS MER

7. 20. Exploring low-carbon development pathways for Bolivia - A model-based analysis focused on the energy sector

   Författare :Jenny Gabriela Peña Balderrama; Viktoria Martin; Mark I. Howells; Dilip Khatiwada; Francesco Gardumi; Pachauri Shonali; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decarbonization; Sustainability; Techno-economic analysis; Bolivia; Energy access; Energy security; Systems analysis; Energy Technology; Energiteknik;

   Sammanfattning : Global emissions have continued to rise steadily at levels exceeding the 1.5°C climate stabilization target. Therefore, the increase in the average global temperature and climate change will be determined by how we handle greenhouse gas (GHG) emissions over the next years. LÄS MER
