  4. 2. Strong L1 convergence to equilibrium without entropy conditions for the spatially homogenous Boltzmann equation

    Author : Fredrik Abrahamsson; Jönköping University; []
    Keywords : ;

    Abstract : This paper deals with solutions to the Cauchy problem for the spatially homogeneous non-linear Boltzmann equation. The main result is that for the hard sphere kernel, a solution to the Boltzmann equation converges strongly in L1 to equilibrium given that the initial data f0 belongs to L1(R^3;(1+v^2)dv).

  5. 3. Improving the functionality of synchronous machines using power electronics

    Author : Fredrik Evestedt; Urban Lundin; C. Johan. D. Abrahamsson; Jon Kjellin; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power electronics; Synchronous machines; Excitation systems; Magnetic thrust bearing; Starting synchronous machines; Split rotor; Rotating electronics; Magnetic fields; Measurement systems; Unbalanced magnetic pull; Harmonics; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : With the advent of modern power electronics there is reason to explore what can be achieved when it is applied to a mature technology like synchronous machines. In this text several concepts will be presented on how it is possible to control forces and how to get better performance out of synchronous machines by using power electronics. READ MORE

  6. 4. Unpacking Online Retailing : The Organization of Warehouse Work and Inequality

    Author : Klara Rydström; Lena Abrahamsson; Kristina Johansson; Fredrik Sjögren; Kristina Boréus; Luleå tekniska universitet; []
