    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; parking; deep learning; pollution; cruising; detection; tracking; forecasting;

    Abstract : Parking is a common process performed by vehicle drivers when they arrive at their destination. It is considered to be the last mile transportation problem of personal vehicles. Some of the common problems observed by drivers are additional cruising, congestion, pollution, and driver frustration. READ MORE

  4. 2. Development and application of Differential Optical Absorption Spectroscopy (DOAS) for Asian urban air monitoring and atmospheric research

    Author : Yu Yong; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asian cities; air pollution; DOAS; free radicals; aerosol; long-path absorption; emission sources; industrial emission; atmospheric chemistry;

    Abstract : Urban air pollution is a serious concern in developing countries and there is a need for qualified measurements of a range of compounds on a nation-wide basis. A suitable potential technique for air monitoring is Differential Optical Absorption Spectroscopy (DOAS). READ MORE

  5. 3. Nutrient imbalance in Norway spruce

    Author : Gunnar Thelin; Avdelningen för kemiteknik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silviculture; Växtekologi; Plant ecology; nitrogen saturation; base saturation; pH; multiple limitation; deficiency; copper; boron; potassium; pollution; sustainability; conifers; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära;

    Abstract : The studies presented in my thesis indicate that growing Norway spruce in monoculture does not constitute sustainable forest management in a high N and S deposition environment, such as in southern Sweden. The combination of N-induced high growth rates and leaching due to soil acidification causes soil reserves of nutrients to decrease. READ MORE

  6. 4. Multiple Imaginaries of the Fossil Fuel Free Future : Biogas and Electricity in Swedish Urban Transport

    Author : Amelia Mutter; Harald Rohracher; Jane Summerton; Magdalena Kuchler; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sociotechnical imaginaries; biogas; electric vehicles; obduracy; sociotechnical change; urban transport; sociotekniska föreställningar; biogas; elfordon; tröghet; sociotekniska förändring; stadstrafik;

    Abstract : I kölvattnet av klimatkrisen har det blivit allt tydligare att det fossilbaserade transportsystemet måste genomgå en global omvandling. Många alternativ för förnyelsebara drivmedel har föreslagits, alla omgivna av föreställningar om hur dessa tekniker kommer att bidra till en bättre framtid. READ MORE

  7. 5. The effects of exposure to microplastics and pollutants on the arthropod microbiome
