  2. 1. Supersymmetry vis-à-vis Observation : Dark Matter Constraints, Global Fits and Statistical Issues

    Author : Yashar Akrami; Joakim Edsjö; Lars Bergström; Roberto Trotta; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; supersymmetry; cosmology of theories beyond the Standard Model; dark matter; gamma rays; dwarf galaxies; direct detection; statistical techniques; scanning algorithms; genetic algorithms; statistical coverage; Astroparticle physics; Astropartikelfysik; Cosmology; Kosmologi; Astroparticle physics; Astropartikelfysik; teoretisk fysik; Theoretical Physics;

    Abstract : Weak-scale supersymmetry is one of the most favoured theories beyond the Standard Model of particle physics that elegantly solves various theoretical and observational problems in both particle physics and cosmology. In this thesis, I describe the theoretical foundations of supersymmetry, issues that it can address and concrete supersymmetric models that are widely used in phenomenological studies. READ MORE

  4. 2. Equal opportunities? : a cross-national comparison of immigrant organisations in Sweden and Italy

    Author : Roberto Scaramuzzino; Malmö högskola; []
    Keywords : corporatism; social welfare; integration; civil society; diversity; political opportunity structures; resource mobilisation; cross-national research; immigrant organisations;

    Abstract : Abstract This thesis concerns the role played by immigrant organisations today. It focuses on the way in which the national context and especially the corporative, social welfare, and integration systems affect such roles. READ MORE

  5. 3. DNA fragility in the context of neural stem cell fate : a multi-method integrative exploration of genome dynamics

    Author : Roberto Ballarino; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Recent advances in mapping the complex genetic architecture underlying various debilitating brain disorders have enabled identification of several genetic risk variants. However, these risk variants only explain part of the heritability and vulnerability to these disorders in early development. READ MORE

  6. 4. Run-Up Transient Analysis for Salient Pole Wound Field Synchronous Motors : Field winding and power electronics implications for a smoother and cooler asynchronous start

    Author : Roberto Felicetti; Urban Lundin; Andreas Binder; Uppsala universitet; []
    Keywords : apparent resistance; cable modeling; current control; transmission line model; eddy currents; field winding; frequency analysis response; Fourier Transform; impedance mismatch; main inductance; overvoltage; parasitic capacitance; partial discharge; quality factor; ringing; slew rate; stray inductance; voltage gradient; winding resonance frequency; asynchronous start; run-up; torque ripple; reluctance torque; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : Salient Pole Wound Field Synchronous Machines have better efficiency at full load than asynchronous machines of the same capability. Moreover, where asynchronous machines need inherently to draw a magnetizing current from the grid, Salient Pole Wound Field Synchronous Machines can work efficiently at unity power factor. READ MORE

  7. 5. A System, Tools and Algorithms for Adaptive HTTP-live Streaming on Peer-to-peer Overlays

    Author : Roberto Roverso; Seif Haridi; Jim Dowling; Alberto Montresor; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; peer-to-peer; distributed caching; nat traversal; congestion control; adaptive HTTP streaming; live streaming; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Abstract : In recent years, adaptive HTTP streaming protocols have become the de facto standard in the industry for the distribution of live and video-on-demand content over the Internet. In this thesis, we solve the problem of distributing adaptive HTTP live video streams to a large number of viewers using peer-to-peer (P2P) overlays. READ MORE
