  1. 1. Exploring models of time processing : effects of training and modality, and the relationship with cognition in rhythmic motor tasks

    Författare :Olympia Karampela; Guy Madison; Linus Holm; Fredrik Ullén; Simon Grondin; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; timing; motor timing; cogntion; dedicated models; intrinsic models; timing variability;

    Sammanfattning : Timing can be defined as the ability to perceive temporal sequences and regulate timed behaviors. As in other animals, our ability to make accurate time estimations is crucial in order to accomplish several activities. Organisms can process time over a wide range of durations ranging from microseconds to days. LÄS MER

  3. 2. Feed-forward Control and Dynamic Modelling in Temperature Control of Buildings

    Författare :Mohsen Soleimani-Mohseni; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building models; state space models; feedback; thermostats; transfer function models; intelligent buildings; ON-OFF controllers; Feed-forward; PIL controllers;

    Sammanfattning : This thesis is mainly about the investigations of different control strategies (and in particular feed-forward) in order to improve indoor climate and/or save energy in buildings. One part of the thesis deals with different ways to obtain dynamic models for climate systems in buildings. LÄS MER

  4. 3. On the Mean Square Error of Transfer Function Estimates with Applications to Control

    Författare :Svante Gunnarsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mean square error; Transfer function; Estimation; Applications;

    Sammanfattning : In this report we study the mean square error of transfer function estimates obtained by identification. The model quality is related to the use of models in regulator design, and the properties of affecting the bias part of the mean square error, both in fixed parameter control and adaptive control.

  5. 4. Applications of the Complex Modulation Transfer Function on SEA-systems

    Författare :Karl-Ola Lundberg; Teknisk akustik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum technology; hydraulics; Mechanical engineering; modulated noise; in-situ; modulation transfer function; loss factor; SEA; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Sammanfattning : The SEA coupling and dissipation loss factors are determined in-situ from Complex Modulation Transfer Functions, CMTF:s, based on measured impulse-responses. A quotient of CMTF:s is least-square curve-fitted to a SEA model and the SEA loss factors are determined from the results of the curve-fit. LÄS MER

  7. 5. Preliminary estimation of transfer function weights : a two-step regression approach

    Författare :Per-Olov Edlund; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : In economic time series modelling, dynamic relationships frequently have to be modelled where the explanatory variables influence the dependent variable over more than one period. Such dynamic relationships are found in business cycle forecasting with leading indicators, in marketing models describing the relationship between advertising and sales, and in many traditional econometric models.
