  1. 16. Particle emissions from car brakes : The influence of contact conditions on the pad-to-rotor interface

    Författare :Mattia Alemani; Ulf Olofsson; Jens Wahlström; Anders Söderberg; Staffan Jacobson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Car brakes emissions; transition temperature; working conditions; environmental design; pin-on-disc; Bilbromsutsläpp; övergångstemperatur; arbetsförhållanden; miljödesign; pinne-på-skiva; Machine Design; Maskinkonstruktion;

    Sammanfattning : Due to their adverse health effects emissions have been regulated for over three decades. Brake wear particulate matter is the most important non-exhaust source, however current knowledge is mainly limited to observational studies. LÄS MER

  3. 17. Energy Efficient Machine-Type Communications over Cellular Networks : A Battery Lifetime-Aware Cellular Network Design Framework

    Författare :Amin Azari; Guowang Miao; Jens Zander; Cedomir Stefanovic; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine-type communications; Internet-of-things; 5G; Battery lifetime; Energy efficiency; maskin-typ kommunikation; Sakernas Internet; 5G; Energieffektivitet; Batteriets livslängd; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Internet of Things (IoT) refers to the interconnection of uniquely identifiable smart devices which enables them to participate more actively in everyday life. Among large-scale applications, machine-type communications (MTC) supported by cellular networks will be one of the most important enablers for the success of IoT. LÄS MER

  4. 18. On Alternative Fuels for Internal Combustion Engines : A study of biodiesel, gaseous methane and methanol

    Författare :Ludvig Adlercreutz; Andreas Cronhjort; Ola Stenlåås; Magnus Sjöberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaseous methane combustion; spark ignition; single cylinder research engine; particle number; particle emissions; oil ash content; CO2; Green House Gases; engine testing; engine development; emissions; combustion chamber design; injector fouling; environmental impact; road transportation; Machine Design; Maskinkonstruktion;

    Sammanfattning :  This thesis covers some of the environmental impacts of internalcombustion engines running on alternative fuels. The focus of thestudies conveyed is the reduction of greenhouse gases and particleemissions, as these two factors are of great importance for the pathsthat road transportation is facing. LÄS MER
