  1. 31. An Ontology-Based Platform for Information Integration : Supporting Sustainable Smart Transportation Infrastructure

    Författare :Wiebke Belitz-Hellwich; Nicole Kringos; Annika Gram; Romain Balieu; Vangelis Angelakis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Ontology; Semantic Web; Interoperability; Information Integration; Logistics; Simulation; Smart Port; ontologi; semantisk webb; interoperabilitet; informationsintegration; logistik; simulering; smart hamn.; Bro- och stålbyggnad; Structural Engineering and Bridges;

    Sammanfattning : Transportation and transportation infrastructure are major contributors to global emissions. Even though most of these emissions can be attributed to fuel consumption of vehicles, some of it is due to pavement construction and maintenance. LÄS MER

  3. 32. Homogeneous Lean Combustion in Downsized Spark-Ignited Engines

    Författare :Kristoffer Clasén; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; lean combustion; emissons; transportation;

    Sammanfattning : Emissions of greenhouse-gasses and noxious compounds from internal combustion engines propelling personal transportation vehicles is an imminent issue in the society. Therefore, it is vital to find means of reducing these emissions to decrease the impacts of transportation. LÄS MER

  4. 33. Exploring Support Infrastructures for Freight Transport Operations

    Författare :Andreas Hagen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Logistics; Intelligent Transport Systems; Infrastructure; Information Systems; Transportation;

    Sammanfattning : Previous publications on freight transport operations have outlined the need for increased effectiveness and better use of information in transport operations. A key to this is the availability and accessibility of information to improve management of transport operations. LÄS MER

  5. 34. Forest-Fuel Systems : Comparative Analyses in a Life Cycle Perspective

    Författare :Lisa Näslund Eriksson; Leif Gustavsson; Antti Asikainen; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest fuels; recovery systems; transportation; cost; primary energy use; CO2 emission; forest-fuel potential; life cycle perspective; Environmental engineering; Miljöteknik;

    Sammanfattning : Forest fuels can be recovered, stored and handled in several ways and these different ways have different implications for CO2 emissions. In this thesis, comparative analyses were made on different forest-fuel systems. The analyses focused on the recovery and transport systems. LÄS MER

  7. 35. Transport policy analysis using multi-agent-based simulation

    Författare :Linda Ramstedt; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transportation; Transport chain; Multi-agent-based simulation; Transport policy; Logistics; Decisions;

    Sammanfattning : This thesis explores how multi-agent-based simulation can be used for transport policy analysis. Transport policies are often used as a means to reach governmental goals, such as environmental targets to reduce the impact of transportation. LÄS MER
