  1. 6. Optimal design solutions of road bridges considering embedded environmental impact and cost

    Författare :Elisa Khouri Chalouhi; Raid Karoumi; Costin Pacoste; Mario Plos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural optimization; Automated design; Road bridges; Environmental impact; Global warming potential; Cost; Overhang bridge slab; Edge beam; Composite bridges; Strukturell optimering; Automatiserad dimensionering; Vägbroar; Miljöpåverkan; Global uppvärmningspotential; Kostnad; Överhängande broplatta; Kantbalk; Kompositbryggor.; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Sammanfattning : Continuous urbanization and population growth are increasing the demand for transportation infrastructure such as bridges. The construction of these structures represents a significant economic investment for public authorities; moreover, the construction sector accounts for a big portion of CO2 emissions. LÄS MER

  3. 7. Perspectives on Demand Side Energy Efficiency

    Författare :Olof Björkqvist; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transaction cost; energy efficiency; energy conservation; viable system model; Markal; demand-side management; local energy planning; organisational cybernetics; reference energy system; decision support; case study;

    Sammanfattning : This work treats recommendations based on energy systems engineering. The focus is on what can be learned by different methods about the roles that demand-side energy efficiency should play in the energy system. LÄS MER

  4. 8. Clean development Mechanism (CDM) Policy and Implementation in China

    Författare :Lei Zeng; Leif Gustavsson; Mälardalens högskola; []
    Nyckelord :Climate change; Clean development mechanism; CDM; CO2; Green House Gas; GHG; landfill gas; sustainable development; China; Energi- och miljöteknik;

    Sammanfattning : China is the second largest emitter of greenhouse gases (GHG) in the world. Since 68% of its primary energy is from coal, China’s average energy intensity is 7.5 times higher than the EU and 4.3 times higher than the US (EU, 2003). LÄS MER

  5. 9. A Techno-Economic Framework for the Analysis of Concentrating Solar Power Plants with Storage

    Författare :Rafael Guédez; Björn Laumert; Zhor Hassar; Viktoria Martin; Alberto Traverso; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concentrating solar power; thermal energy storage; techno-economic analysis; Termisk solkraft; termisk energilagring; techno-eknomiska analys; Energiteknik; Energy Technology;

    Sammanfattning : Concentrating solar power plants can integrate cost-effective thermal energy storage systems and thereby supply controllable power on demand, an advantage against other renewable technologies. Storage integration allows a solar thermal power plant to increase its load factor and to shift production to periods of peak demand. LÄS MER

  7. 10. Systemförvaltningsmodeller

    Författare :Peder Brandt; Institutionen för informatik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; software life cycle; system life cycle; perfective maintenance; adaptive maintenance; corrective maintenance; business maintenace model; maintenance model; Software maintenance; maintenance process; software maintenance management; Systems engineering; computer technology; Data- och systemvetenskap;

    Sammanfattning : The term Software Maintenance was coined in the early 1970s. The subject has significance from several points of view. The costs associated with software maintenance are as a rule considerably higher than what the system cost to develop, which is borne out by many studies conducted in different countries over a period of twenty years.
