  1. 1. Non-contact surface wave measurements on pavements

    Author : Henrik Bjurström; Nils Rydén; Björn Birgisson; Jinying Zhu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; seismic testing; asphalt concrete; dynamic modulus; non-contact measurements; rolling measurements; surface waves; Lamb waves; MEMS microphones; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : In this thesis, nondestructive surface wave measurements are presented for characterization of dynamic modulus and layer thickness on different pavements and cement concrete slabs. Air-coupled microphones enable rapid data acquisition without physical contact with the pavement surface. READ MORE

  2. 2. Non-contact measurement systems in robotics and telerobotics

    Author : Mats Blomquist; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : In robotics, and particularly in telerobotics, non-contact measurement methods are widely used. In this thesis, systems are investigated with the range camera as the main sensor component. It is desirable that remotely controlled robot systems have a high degree of autonomy. READ MORE

    Author : Dietrich Buck; Olle Hagman; Dick Sandberg; Mats Ekevad; Mikael Sjödahl; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CLT assembly; CLT manufacture; Crosslam; DIC analysis; Digital speckle photography; Full-field mechanics; Laminated wood product; Mass timber engineering; Non-contact measurement; Non-destructive; Optical measurement; Panel configuration; Strain localization; X-lam; Alternativ byggmetod; Bildkorrelation; Hållbart byggande; KL- trä; Korslimmat trä; Skjuvtöjning; Massivträ; Träkonstruktion; Träteknik; Wood Science and Engineering;

    Abstract : Increasing awareness of sustainable building materials has led to interest in enhancing the structural performance of engineered wood products. Wood is a sustainable, renewable material, and the increasing use of wood in construction contributes to its sustainability. READ MORE

  4. 4. Enhanced Dielectric Response Methods for the Characterization of Dielectric Materials

    Author : Jing Hao; Nathaniel Taylor; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FDS; non-contact; dielectric response; combined AC and DC; space-charge polarization;

    Abstract : Dielectric response measurement is widely used for condition assessment of high voltage equipment and for characterizing candidate materials. Measurement with high accuracy and reliability is important in all stages of the lifetime of high voltage equipment, from manufacture to replacement decision. READ MORE

  5. 5. Non-contact measurements and modelling of milling machine tool vibrations

    Author : Matti Rantatalo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

    Abstract : This thesis concerns the development of non-contact measurement methods and analysis of rotors. The methods have been verified and applied to milling machine spindles in order to investigate the speed dependency in the milling machine spindle dynamic. The research was financed by the Swedish Agency for Innovation Systems (Vinnova). READ MORE
