  1. 1. Avian thermoregulation across age and seasons

    Författare :Fredrik Andreasson; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ambient temperature; body temperature; Cyanistes caeruleus; energy expenditure; hypothermia; life-history theory; metabolic rate; Parus major; thermoregulation; trade-off; winter ecology;

    Sammanfattning : Animals constantly need to relate to prevailing environmental conditions and regulate their body temperature accordingly. Body temperature regulation in birds and mammals is inherently linked to energy expenditure and, thus, thermoregulation is a physiological mechanism that could trade-off with other costly processes, with potential long-term fitness consequences.

  4. 3. Retande, berättelser och kategoriseringar : Om vänskap och kärlek i barns relationsprat

    Författare :Fredrik Andreasson; Ann-Carita Evaldsson; Johanna Svahn; Rickard Jonsson; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Peer interaction; relational talk; friendship; romantic relationships; teasing; storytelling; assessments; middle-school; ethnography; talk-in-interaction; conversation analysis; membership categorization analysis; Pedagogik; Education;

    Sammanfattning : This thesis focuses on how middle school children organize peer group relationships through various forms of so-called relational talk (Evaldsson, 2007), while they also negotiate and more generally make sense of friendships and romantic relationships. Prior micro-sociological research has demonstrated how children in everyday language practices through, for example, teasing, assessments, and storytelling—articulate and manage social relationships and behaviors, moral views, and shared cultural knowledge, thereby constructing their emerging social worlds (see Goodwin & Kyratzis, 2011, for an overview).

  7. 5. Automation of Navigation During the Short-loading Cycle Using Machine Vision

    Författare :Carl Borngrund; Ulf Bodin; Fredrik Sandin; Jerker Delsing; Henrik Andreasson; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Automation; Short-loading cycle; Construction equipment; Deep Learning; Computer Vision; Cyber-Physical Systems; Cyberfysiska system;

    Sammanfattning : Earth-moving machines are machines used in a wide range of industries, such as the construction industry, to perform tasks related to earthworks.Currently, the vast majority of earth-moving machines are human-operated where expert operators perform these industry vital tasks.
