  2. 1. Engineering Magnetic Droplets in Nanocontact Spin-Torque Nano-Oscillators

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Shaping Risk Management in Banks

    Author : Vikash Kumar Sinha; Mats Engwall; Håkan Kullvén; Torkel Strömsten; Marika Arena; Andrea Mennicken; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; internal audit; risk management; risk culture; Basel models; operational risk; liquidity risk; internrevision; riskhantering; riskkultur; Baselmodellerna; operativ risk; likviditetsrisk; Industriell ekonomi och organisation; Industrial Economics and Management; Business Studies; Företagsekonomi;

    Abstract : The recent financial crisis of 2007-08 was a watershed moment in the history of banking. The unprecedented event led to severe scrutiny by standard setters and regulators on how the business of banking is run. As a result of this strict scrutiny, a wide variety of reforms aimed at the second line of defense (risk management) ensued globally. READ MORE

  7. 5. Grasping the Peripheral State : A Historical Sociology of Nicaraguan State Formation

    Author : Anders Neergaard; Sociologiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; national arena; international arena; integrative capacity; repressive capacity; extractive capacity; international system of states; world capitalist economy; colonial legacy; peripheral state; nation-state; state formation; Historical political sociology; state forms; state arena; infrastructural power; despotic power.; Sociology; Sociologi;

    Abstract : The thesis has two aims. The first one is to contribute to the field of political and historical sociology through an understanding of the processes of state formation in a Third World country. The second aim is to describe and analyze the development of the Nicaraguan state from independence to 1990. READ MORE
