  1. 1. Combining cognitive and physical work tasks: Short-term effects on fatigue, stress, performance and recovery

    Författare :Susanna Mixter; Svend Erik Mathiassen; David Hallman; Petra Lindfors; Paul Jarle Mork; Högskolan i Gävle; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physical; repetitive; cognitive; mental; load; variation; job rotation; restoration; allostatic load; fysisk; repetitiv; kognitiv; mental; belastning; variation; arbetsrotation; återhämtning; allostatisk belastning; Health-Promoting Work; Hälsofrämjande arbete;

    Sammanfattning : Background: Although combinations of physical and cognitive work tasks occurs in working life (both concurrent and alternating), no one has summarized the research regarding such combinations. Very few studies have investigated the effects of alternating physical and cognitive tasks, which have been suggested as an alternative to classic job rotation. LÄS MER

  3. 2. Non-formal Learning through Ludic Engagement within Interactive Environments

    Författare :Eva Petersson; Utbildningsvetenskap; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; didaktik; Pedagogik; Pedagogy and didactics; sensorteknologi; rehabilitering; intuitiv interaktion; interaktiva miljöer; interaktiv lek; icke-formellt lärande; handling; fallstudier; Aktivitet; sensor technology; rehabilitation; non-intrusive interface; non-formal learning; intuitive interaction; interactive play; interactive environments; case studies; Action; activity; non-formal learning;

    Sammanfattning : daptive responsive environments that encourage interaction for children with severe disabilities offer a distinct potential for play and learning in rehabilitation. Physical training and therapy for these children is often enduring, tedious, and boring through repetition - and this is often the case for both the child and the facilitator/therapist. LÄS MER

  4. 3. Lean culture in industrialized housing : a study of timber volume element prefabrication

    Författare :Matilda Höök; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : Industrialization and the use of timber have been put forward by means of its potential for increased efficiency in housing construction. Industrialized housing is related to learning from manufacturing, but the construction culture still has to be considered when development is discussed. LÄS MER

  5. 4. Picosecond X-ray Diffraction Studies of Bulk and Nanostructure Materials

    Författare :Andrius Jurgilaitis; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; solid-liquid transitions; X-ray diffraction and scattering; nanowires; laser beam impact phenomena; phonons in crystal lattices; Fysicumarkivet A:2012:Jurgilaitis;

    Sammanfattning : Fast phenomena occurring after laser excitation were studied using time-resolved X-ray diffraction (TXRD). In most experiments, a femtosecond laser pulse was used to excite the sample, and X-rays were used as a probe. LÄS MER

  7. 5. On Kinematic Modelling and Iterative Learning Control of Industrial Robots

    Författare :Johanna Wallén; Mikael Norrlöf; Svante Gunnarsson; Geir Hovland; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial robots; kinematics; Maple; modelling; iterative learning control; experiments; Automatic control; Reglerteknik;

    Sammanfattning : Good models of industrial robots are necessary in a variety of applications, such as mechanical design, performance simulation, control, diagnosis, supervision and offline programming. This motivates the need for good modelling tools. In the first part of this thesis the forward kinematic modelling of serial industrial robots is studied. LÄS MER
