  1. 1. Journal bearing design, lubrication and operation for enhanced performance

    Author : Gregory F Simmons; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The increasing introduction of intermittent power sources combined with the de-regulation of electricity markets has led to increased instability in the electrical grid. This has led to increased start-up and shutdown of regulating power sources such as hydro-electric power plants and operation at non-ideal operating states both of which increase the wear and tear on machines.

  2. 2. Using Connected Vehicles in Variable Speed Limit Systems: : System Design and Effects

    Author : Ellen F. Grumert; Jan Lundgren; Andreas Tapani; Francesc Soriguera; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Motorway traffic management systems are useful for improving the traffic conditions on urban motorways. One of the most common motorway traffic management systems are variable speed limit systems. READ MORE

  3. 3. Neutrophils versus Pathogenic Fungi : through the magnifying glass of nutritional immunity

    Author : Maria Joanna Niemiec; Constantin F. Urban; Bernhard Hube; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neutrophils; Candida albicans; nutritional immunity; metallome; Zn; Fe;

    Abstract : Neutrophils are among the first white blood cells recruited to the site of infection once microbial pathogens enter the host organism. At site, they perform a well-orchestrated chain of processes that aims to kill the microbial invader. Most prominent, neutrophils engulf microbes to inactivate them intracellularly, a process called phagocytosis. READ MORE

  4. 4. A Multichoice Control Strategy for a VSC-HVdc

    Author : Hector F. Latorre; Mehrdad Ghandhari; Lennart Söder; Kjetil Uhlen; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Control Lyapunov Function; Modal Analysis; Power Oscillation Damping; Transient Stability; Voltage Stability; VSC-HVdc; Electrical engineering; Elektroteknik;

    Abstract : Utilization of power electronics based controllable systems (or devices) in transmission systems has opened new opportunities for the power industry to optimize utilization of the existing transmission systems, and at the same time to keep high system reliability and security. As a member of these controllable systems, Voltage Source Converters-based High Voltage direct current (VSC-HVdc) systems have the ability to rapidly control the transmitted active power, and also to independently exchange reactive power with transmissions systems.

  5. 5. Design and Performance of Some Components for a Millimeter Wave Imaging Receiver

    Author : Guillermo F. Delgado Gunckel; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nipi MQW; imaging receiver; lens shaping; diplexer; kinoform; opto-electronic quasi-optical modulation; dielectric lenses; sideband filter; diffractive optics;

    Abstract : This thesis deals with the design and performance of some novel devices for an imaging receiver, operating in the frequency band centered at 100 GHz, to be used in radio astronomy research. The emphasis is given on simple, small and reliable devices in order to reduce the complexity of an already complex receiver. READ MORE
