  2. 1. Gearbox noise : Correlation with transmission error and influence of bearing preload

    Author : Mats Åkerblom; Sören Andersson; D. Houser; KTH; []
    Keywords : gear; gearbox; noise; vibration; transmission error; bearing preload; Mechanical engineering; Maskinteknik;

    Abstract : The five appended papers all deal with gearbox noise and vibration. The first paper presents a review of previously published literature on gearbox noise and vibration. The second paper describes a test rig that was specially designed and built for noise testing of gears. READ MORE

  4. 2. Development and Application of Reactor Noise Diagnostics

    Author : Joakim K.-H. Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BWR stability; noise decomposition; reactor noise; control rod vibrations; core barrel vibration; density wave oscillations; noise diagnostics; PWR noise; localisation; channel instability;

    Abstract : A number of problems in reactor noise diagnostics have been investigated within the framework of the present thesis. The six papers presented cover three relatively different areas, namely the use of analytical calculations of the neutron noise in simple reactor models, some aspects of boiling water reactor (BWR) stability and diagnostics of core barrel motion in pressurized water reactors (PWRs).

    Abstract : High electron mobility transistor (InP HEMT) cryogenic low noise amplifiers (LNAs) have made significant improvements in noise and gain following decades of development. Applications are found from radio astronomy to quantum computing. READ MORE

  6. 4. Development of a Noise-Based Method for the Determination of the Moderator Temperature Coefficient of Reactivity (MTC) in Pressurized Water Reactors (PWRs)

    Author : Christophe Demaziere; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; point-kinetics; Decay Ratio DR ; Gamma-Thermometer GT ; temperature noise structure of the ; correlation length; boron dilution method; noise analysis; core calculations; dynamic reactor transfer function; moderator temperature coefficient MTC ;

    Abstract : The Moderator Temperature Coefficient of reactivity (MTC) is an important safety parameter of Pressurized Water Reactors (PWRs). In most countries, the so-called at-power MTC has to be measured a few months before the reactor outage, in order to determine if the MTC will not become too negative. READ MORE
