    Nyckelord :Transportation; Car ownership; Shared mobility; Mobility-as-a-Service; MaaS; Disincentives; Reykjavík;

    Sammanfattning : Iceland faces problems in achieving decarbonization goals, especially regarding its transportation sector having highly car-oriented passenger transport in the capital city, Reykjavík. Therefore, there is a need to shift toward more sustainable transport modes. LÄS MER

  3. 2. Hydraulic Characterization of Diesel Engine Single-Hole Injectors

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Javier Arco Sola; [2015]
    Nyckelord :;

    Sammanfattning : Due to world trend on the emission regulations and greater demand of fuel economy,the research on advanced diesel injector designs is a key factor for the next generation diesel engines. For that reason, it is well established that understanding the effects of the nozzle geometry on the spray development, fuel-air mixing, combustion and pollutants formation is of crucial importance to achieve these goals.

  4. 3. Context-Aware Machine to Machine Communications in Cellular Networks

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Javier Mendonca Costa; [2013]
    Nyckelord :Context-Awareness; Energy Efficiency.;

    Sammanfattning : Cellular network based Machine-to-Machine (M2M) communications have been growing rapidly in recent years, being used in a wide range of services such as security, metering, health, remote control, tracking and so on. A critical issue that needs to be considered in M2M communications is the energy efficiency, typically the machines are powered by batteries of low capacity and it is important to optimize the way the power is consumed.

    Nyckelord :wireless sensor gateway; microcontoller; power over ethernet;

    Sammanfattning : The great interest in monitoring everything around us has increased the number of sensors that we utilize in our daily lives. Furthermore, the evolution of wireless technologies has facilitated their ubiquity. Moreover, is in locations such as homes and offices where exploitation of the data from these sensors has been more important. LÄS MER

  7. 5. Characterization of activated carbon produced from coffee residues by chemical and physical activation

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Javier Sanchez; [2011]
    Nyckelord :activated carbon; coffee residues; chemical acivation; physical activation; surface characteristics;

    Sammanfattning : Activated carbons are one of the most used adsorbents with lots of applications in many sectors. Activated carbons can be produced from lignocellulosic materials with a large content of carbon. Coffee is the second trade most consumed all over the world; hence their residues can be treated in order to give a value. LÄS MER
