  1. 1. Möjligheternas arena? : Barns och ungas samtal om tjejer, killar, känslor och sexualitet på en virtuell arena

    Författare :Cecilia Löfberg; Sonja Olin Lauritzen; Lars Jalnert; Karin Zetterqvist Nelson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Children; Gender; Generation; Internet; Social interaction; Young people; Education; Pedagogik; pedagogik; Education;

    Sammanfattning : Computer mediated communication (CMC) has created new arenas for social interaction in contemporary society, also for children and young people. This raises questions about how these arenas are used by children and young people. LÄS MER

  3. 2. Vi är bara några kompisar som träffas ibland : Rotary som en manlig arena

    Författare :Robert Hamrén; Kirsti Niskanen; Mark Graham; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Rotary; gender pattern in organisations; masculinity; femininity; self-made man; homosociality; doing gender; gender complentarity; fraternity; middle class; normality; Rotary; könsmönster i organisationer; maskulinitet; feminitet; self made man; homosocialitet; doing gender; könskomplementaritet; broderskap; medelklass; normalitet; Gender studies; Genus;

    Sammanfattning : I den här avhandlingen undersöks vilka dolda köns- och klassmässiga uttryck som omgärdar organisationen Rotary och dess medlemmar. Boken riktar in sig på de ideal och självbilder som organisationen producerar. LÄS MER

  4. 3. Engineering Magnetic Droplets in Nanocontact Spin-Torque Nano-Oscillators

    Författare :Sheng Jiang; Johan Åkerman; Dario Arena; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetic Droplet; Magnetic Tunnel Junction; Perpendicular Magnetic Anisotropy; Spin-torque Nano-Oscillators; Spin-Valve.; Physics; Fysik;

    Sammanfattning : Spin-torque nano-oscillators (STNOs) are nanoscale spintronic devices capable of generating highly tunable broadband microwave signals. In this thesis, I study nanocontact (NC)-based STNOs using strong perpendicular magnetic anisotropy(PMA) free layers, where a novel magnetic soliton—a magnetic droplet—exists. LÄS MER

  5. 4. Linear, Non-Linear, and Synchronizing Spin Wave Modes in Spin Hall Nano-Oscillators

    Författare :Hamid Mazraati; Johan Åkerman; Dario Arena; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; spin Hall effect; spin Hall nano-oscillators; threshold current; microwave; spin wave; synchronization; Fysik; Physics;

    Sammanfattning : Spin Hall nano-oscillators (SHNOs) are nanoscale spintronic devices that generate microwave signals with highly tunable frequency. This thesis focuses on improving the signal quality of nanoconstriction-based SHNOs and also on developing a better understanding of their magnetization dynamics. LÄS MER

  7. 5. Modelling of  Ocean Wave Energy Conversion for Increased Power Absorption

    Författare :Tatiana Potapenko; Irina Temiz; Cecilia Boström; Sandra Eriksson; Felice Arena; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : The Earth is also called the blue planet, because more than 70 % of its surface is covered by water, mainly in oceans and seas. Wind blowing over the oceans is creating water waves, which can travel thousands of kilometers with just a small energy loss. LÄS MER
