  1. 1. Random and Hybrid Medium Access for M2M Communication : Scalability and Energy Analysis

    Författare :Luca Beltramelli; Mikael Gidlund; Patrik Österberg; Aamir Mahmood; Preben Mogensen; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; M2M; LoRa; IEEE 802.1ah; energy; mathematical modeling;

    Sammanfattning : The term machine-to-machine (M2M) communication identifies any fully automated communication between intelligent devices, autonomous from human intervention. M2M communication is a key enabling technology for the Internet of Things (IoT), where it is used to provide ubiquitous connectivity between a large number of intelligent devices. LÄS MER

  3. 2. Study of generation, growth and breakdown of streamwise streaks in a Blasius boundary layer

    Författare :Luca Brandt; KTH; []
    Nyckelord :Fluid mechanics; laminar-turbulent transition; boundary layer flow; transient growth; streamwise streaks; lift-up effect; receptivity; free-stream turbulence; streak instability; secondary instability; Direct Numerical Simulation.;

    Sammanfattning : Transition from laminar to turbulent flow has beentraditionally studied in terms of exponentially growingeigensolutions to the linearized disturbance equations.However, experimental findings show that transition may occuralso for parameters combinations such that these eigensolutionsare damped.

  4. 3. Discovering Hidden Traps : in Nickel Oxide Nanoparticles for Dye-Sensitised Photocathodes

    Författare :Luca D'Amario; Leif Hammarström; James Durrant; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The finite nature of fossil fuels and their effect on the global climate, raised the need to find an alternative source of energy. This source should be environment compatible, cheap and abundant. The light coming from the Sun is a promising alternative. LÄS MER

  5. 4. On the role of information in educational choice

    Författare :Luca Facchinello; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This Ph.D. thesis in Economics consists of three self-contained chapters that investigate how information affects the choices of students. LÄS MER

  7. 5. A study on axially rotating pipe and swirling jet flows

    Författare :Luca Facciolo; Herik Alfredsson; Helge I. Andersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : The present study is an experimental and numerical investigation on rotating flows. A special facility has been built in order to produce a turbulent swirling jet generated by a fully developed rotating pipe flow and a Direct Numerical Simulation (DNS) code has been used to support and to complement the experimental data.
