  3. 2. Getting a Feel for Tactile Space : Exploring Haptic Perception of Microtexture

    Författare :Martin Arvidsson; Birgitta Berglund; Steven Hsiao; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Haptic; fine texture perception; multidimensional scaling; tactile; roughness; vibrations; spatial; Psychology; psykologi;

    Sammanfattning : The present thesis is based on three studies that research different aspects of fine texture perception. The goal is to better understand the mechanisms involved in haptic perception of textures below 200 µm, also known as microtextures. LÄS MER

  4. 3. Vision Based Perception for Mechatronic Weed Control

    Författare :Björn Åstrand; David Slaughter; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Vision-based perception; Plant recognition; Row following; Weed Control; Mechatronics in agriculture; Mobile robots;

    Sammanfattning : The use of computer-based signal processing and sensor technology to guide and control different types of agricultural field implements increases the performance of traditional implements and even makes it possible to create new ones. This thesis increases the knowledge on vision-based perception for mechatronic weed control. LÄS MER

  5. 4. Nuclear Intonation in Swedish : Evidence from Experimental-Phonetic Studies and a Comparison with German

    Författare :Gilbert Ambrazaitis; Fonetik; []
    Nyckelord :HUMANIORA; HUMANITIES; parallel encoding; contrastive topic; new information; given information; focus; information structure; pragmatics; nucleus; sentence accent; prosody; word accent; F0; early peak; perception; reaction time;

    Sammanfattning : This thesis investigates Swedish intonation patterns and their interaction with word accent realisation in various pragmatic conditions, using German as a reference language. The point of departure is the wide-spread assumption that Swedish, as a language with a tonal word accent distinction, has a considerably smaller repertoire of nuclear intonation contours than German and other so-called intonation languages.

  7. 5. Non-image-forming effects of light : Implications for the design of living and working environments

    Författare :Mathias Adamsson; Thorbjörn Laike; Maria Johansson; Yvonne de Kort; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circadian rhythms; circannual; light exposure; melatonin; cortisol; sleep-wake behavior; perception; mood; spectral composition; measurement;

    Sammanfattning : Seasonal variation in mood and subjective well-being are common at geographical locations further away from the equator. The 24-h light-dark cycle is the main time cue for synchronizing the human circadian clock to the external day and night. LÄS MER
