  1. 36. Infectious diseases in returning Swedish travellers

    Författare :Helena Hervius Askling; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The number of travellers to “tropical” parts of the world has increased substantially during the past decades. Identifying risk groups and providing preventive measures is important both to reduce the number of travellers falling ill and to prevent introduction of diseases into new countries. LÄS MER

  3. 37. Look-ahead Control of Heavy Trucks utilizing Road Topography

    Författare :Erik Hellström; Lars Nielsen; Torkel Glad; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; predictive control; dynamic programming; Automatic control; Reglerteknik;

    Sammanfattning : The power to mass ratio of a heavy truck causes even moderate slopes to have a significant influence on the motion. The velocity will inevitable vary within an interval that is primarily determined by the ratio and the road topography. LÄS MER

  4. 38. Coordination of cross-carrier truck platooning

    Författare :Alexander Johansson; Jonas Mårtensson; Karl H. Johansson; Hani Mahmassani; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The need for sustainable transportation solutions is urgent as the demand for mobility of goods and people is expected to multiply in the upcoming decades. One promising solution is truck platooning, which shows great potential in reducing the energy consumption and operational costs of trucks. LÄS MER

  5. 39. Microstructure of Zirconium Alloys Oxidized in Steam

    Författare :Pia Tejland; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EDX; ADF; TEM; Zircaloy-2; FIB-SEM; STEM; GD-OES; SPP; SEM; Zirconium; HAADF;

    Sammanfattning : Zirconium alloys are widely used in nuclear reactors as fuel cladding tubes because of their low thermal neutron capture cross-section, good corrosion properties and satisfactory mechanical properties. However, the main limiting factor of these materials is the oxidation behavior. LÄS MER

  7. 40. On Battery Electric Vehicles: Driving Patterns, Multi-Car Households and Infrastructure

    Författare :Niklas Jakobsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BEV; battery size; individual movement pattern.; Electro-mobility; GPS-logging;

    Sammanfattning : The transportation sector is responsible for a quarter of all greenhouse gas emissions in Europe. Though the transport system may be difficult to change into a less polluting system, electric vehicles may be a possible approach. LÄS MER
