  1. 1. Noise and Saturation Properties of Fiber Optical

    Author : Per Kylemark; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear fiber optics; four-wave mixing; single-pumped; regeneration; saturation; dual-pumped; noise figure; parametric amplification;

    Abstract : Fiber Optical Parametric Amplifiers (FOPAs) are based on a highly efficient Four-wave Mixing process in highly nonlinearfibers and have gained a lot of interest since it was shown that ahigh gain can be obtained. They are multi-functional devices thatare not only limited to amplifying signals, but their wide range ofapplicability also include wavelength conversion, pulse-generation,optical sampling and also regeneration at very high bit-rates.

  2. 2. Aspects on Wind Turbine Protections and Induction Machine Fault Current Prediction

    Author : Marcus Helmer; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; saturation; Induction generator; Short circuit currents; Slip ring Generator; skin effect;

    Abstract : This thesis presents detailed modelling of the induction machine with the main objective being accurate fault current prediction. The thesis focus mainly on mains connected induction machines and the response due to severe disturbances in the supply voltage, such as three-phase short-circuit faults. READ MORE

  3. 3. Nonlinear Evolution in High Energy QCD

    University dissertation from Theoretical High Energy Physics

    Author : Emil Avsar; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elementarpartikelfysik; quantum field theory; DIS; Elementary particle physics; Saturation; QCD; Small-x Physics; kvantfältteori; High energy interactions; cosmic rays; Kosmisk strålning; högenergi;

    Abstract : QCD at very high energies is still not very well understood. Difficulties arise from a strong non-linear dynamics and also from nonperturbative physics. Detailed analytic calculations are often only possible either for simple toy models, or for asymptotically high energies. READ MORE

  4. 4. Design of a fault-tolerant fractional slot PMSM for a vehicle application

    University dissertation from Theoretical High Energy Physics

    Author : Christian Dubar; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PMSM; Efficiency; Fault-tolerant; Unbalanced operation; Saturation; Fault-tolerance; Fractional slot; Permanent magnet synchronous machine; PMSM ; Concentrated windings;

    Abstract : In automotive applications, the PMSM is an interesting alternative due to the high efficiency requirement; as only a limited amount of energy can be stored in the relatively expensive battery. Another advantage is the high torque and power density since it is very important to save especially space but also weight in vehicle applications. READ MORE

  5. 5. Mehanics of Rock Fragmentation Static and Dynamic Laboratory Testing Applied to Aggregate Production

    University dissertation from Theoretical High Energy Physics

    Author : Bahman Bohloli; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anisotropy; aggregates; rock failure; saturation; Brazilian test; dynamic tensile strength; Hopkinson pressure bar; fragmentation; rock fines; crushing;

    Abstract : Knowing the strength properties of rocks is essential for calculating the stability of natural slopes, constructions in and on rock, excavations, blasting geometry, crushing, and drilling. When rock and rock masses are subjected to either dynamic or static loads, the tensile strength is determined by tests appropriate to the load type. READ MORE
