    Abstract : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. READ MORE

  4. 2. An Experimental and Theoretical Study of the Mass Transport in Lithium-Ion Battery Electrolytes

    Author : Andreas Nyman; Göran Lindbergh; Mårten Behm; Signe Kjelstrup; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium‐ion batteries; Electrolytes; Transport properties; Conductivity; Diffusion coefficients; Transport number; Maxwell-Stefan equation; Simulations; Mathematical analysis; Polarization; Hybrid electric vehicles; Litiumjonbatterier; Aprotiska elektrolyter; Transport egenskaper; Konduktivitet; Diffusion koefficienter; Transporttal; Maxwell-Stefans ekvation; Simuleringar; Matematisk analys; Polarisation; Elhybridfordon; Electrochemistry; Elektrokemi;

    Abstract : Lithium‐ion batteries are particularly suitable as energy storage solutions in high power applications, such as hybrid electric vehicles. It is generally considered that one of the processes that limit the power density for lithium‐ion batteries is the mass transport in the electrolyte. READ MORE

  5. 3. A trinity of sense : Using biomass in the transport sector for climate change mitigation

    Author : Erik G. Lindfeldt; Mats Westermark; Lars J. Nilsson; KTH; []

    Abstract : This thesis analyses two strategies for decreasing anthropogenic carbon dioxide (CO2) emissions: to capture and store CO2, and to increase the use of biomass. First, two concepts for CO2 capture with low capture penalties are evaluated. READ MORE

  6. 4. From Shrieks to Technical Reports : technology, disability and political processes in building Athens metro

    Author : Vasilis Galis; Jane Summerton; Jonas Anshelm; Ingunn Moser; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; co-production; transport disability; symmetry; hybrid collective; accessibility provisions; handbooks; materiality; translation; social model of disability; hybrid forums; concerned groups; configuration of the built environment; samproduktion; transport handikapp; symmetri; hybrid collective; tillgänglighetsåtgärder; handbok; materialitet; översättning; hybrid forums; concerned groups; Technology and social change; Teknik och social förändring;

    Abstract : Avhandlingen beskriver och analyserar hur frågor kring tillgänglighet/handikapp för första gången aktualiserades och implementerades i planeringen och utformningen av den byggda miljön i Aten, nämligen processen i samband med beslut, planering och implementering av jätteprojektet Atens Metro. Studien tecknar framväxten av olika handikapporganisationer, som från att ha varit svaga aktörer successivt lyckades få gehör för sina krav inom stadens förvaltning, politiska organ, den grekiska riksdagen och inte minst inom de företag som byggde metrosystemet.
