  1. 41. Polarization transfer solid-state NMR for studying soft matter: From surfactants to the stratum corneum

    Författare :Agnieszka Nowacka; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The work presented in this thesis is dedicated to theoretical development, experimental testing and application of polarization transfer solid-state nuclear magnetic resonance (PT ssNMR). PT ssNMR is an analytical tool which provides detailed information about molecular mobility in model or simple soft matter systems at the low water content regime, enabling the creation of phase diagrams.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; indoor climate; Environmental engineering; Miljöteknik;

    Sammanfattning : Objectives. The main objective of the present thesis was to evolve a controlled intermittent velocity field and to examine the impact of this type of dynamic indoor climate on human’s psychology and physiology. LÄS MER

  4. 43. Photoplethysmography : methodological studies and applications

    Författare :Lars-Göran Lindberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Photoplethysmography (PPG), an optical non-invasive technique for measuring skin perfusion changes, was investigated and evaluated. The method was compared with laser Doppler flowmetry (LDF) when measuring perfusion changes in human fingers and forearms. LÄS MER

  5. 44. Hybrid Plasmonics for Energy Harvesting and Sensing of Radiation and Heat

    Författare :Mina Shiran Chaharsoughi; Magnus Jonsson; Xavier Crispin; Simone Fabiano; Eunkyoung Kim; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The special optical properties of subwavelength metallic structures have opened up for numerous applications in different fields. The interaction of light with metal nanostructures leads to the excitation of collective oscillations of conduction-band electrons, known as plasmons. LÄS MER

  7. 45. Measurements and Modelling of Low-frequency Disturbances in Induction Machines

    Författare :Torbjörn Thiringer; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modelling; induction machine; measurements;

    Sammanfattning : in this thesis the low-frequency dynamic behavior of the induction machine is analyzed. disturbances in the shaft torque and supply voltage are investigated theoretically, The calculated response to shaft torque disturbances is verified with measurements on a 15 kW machine.
