  1. 1. Noise and music : a matter of risk perception

    Author : Stephen E. Widén; Högskolan Väst; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Adolescents; Tinnitus; Noise sensitivity; Socio-economic status; Attitudes; Use of hearing protection; Risk behaviour; Risk-consideration; Self-image; Norms and Ideals; Psychology; Psykologi; Psychology; Psykologi;

    Abstract : The prevalence of tinnitus and hearing impairments among adolescents seems to increase as a consequence of exposure to loud noise. Several studies have highlighted the negative auditory effects of exposure to loud music at concerts and discotheques, environments in which young people today spend considerable periods of time.

  2. 2. Noise sensitivity and FK-type representations for Gaussian and stable processes

    Author : Malin Palö Forsström; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; color representation; exclusion process; color process; Noise sensitivity; threshold stable vector; volatility; noise stability; interchange process; threshold Gaussian vector; multivariate stable distribution; Bernoulli random vector; mixing time;

    Abstract : This thesis contains four papers on probability theory. Paper A concerns the question of whether the exclusion sensitivity and exclusion stability of a sequence of Boolean functions are monotone with respect to adding edges to the underlying sequence of graphs. READ MORE

  3. 3. Noise Properties of the Single Electron Transistor

    Author : Serguei Kafanov; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Low-Frequency noise; Shot Noise; 1 f noise; Single Electron Transistor; charge sensitivity; SET; electrometer; Coulomb blockade; radio-frequency Single Electron Transistor; RF-SET;

    Abstract : The Single Electron Transistor (SET) is a sensitive electrometer with a charge sensitivityultimately limited by noise. In this thesis we present measurements of noiseproperties and charge sensitivity of the radio-frequency Single Electron Transistor. READ MORE

  4. 4. Noise in the school environment : Memory and Annoyance

    Author : Eva Boman; Högskolan i Gävle; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Noise; meaningful irrelevant speech; road traffic noise; memory; age group; school environment; pupils; teachers;

    Abstract : Objectives.The general objectives of this dissertationwere to examine the effects of acute exposure to meaningfulirrelevant speech and road traffic noise on memory performance,and to explore annoyance responses to noise exposure in theschool environment for pupils and teachers in different agegroups.Methods.

  5. 5. Experimentally Based HFET Modeling for Microwave and Millimeter Wave Applications

    Author : Mikael Garcia; Chalmers University of Technology; []
    Keywords : MODFET; soft-breakdown; cold FET; large-signal; source balance; SDHT; dispersion; noise figure; temperature noise model; small-signal; TEGFET; direct extraction; Chalmers model; noise parameters; modeling; HEMT; HFET; noise;

    Abstract : Transistor models are very important in the design of Monolithic Microwave Integrated Circuits (MMICs). Circuit simulations based on accurate transistor models are one of the keys to high circuit yield. Transistor models can also be used to trace problems in the device fabrication processes. READ MORE
