  2. 1. Gaze Following in Infancy : Mechanisms and Developmental Context

    Author : Kim Astor Währborg; Gustaf Gredebäck; Gergely Csibra; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Gaze following; Eye-tracking; Infants; Mechanisms; Culture; Joint visual attention; Social environment; Theories; Attention sharing; Psychology; Psykologi;

    Abstract : Few things are as fundamental to humans as the ability to share attention. It allows us to coordinate our actions with, and assimilate knowledge from, the actions of others with remarkable efficiency and accuracy. This ability emerges in infancy and sets the stage for all subsequent social development. READ MORE

  4. 2. Micro-mechanical mechanisms for deformation in polymer-material structures

    Author : Jessica Strömbro; Peter Gudmundson; Per Gradin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Length-scale effects; Strain gradient; Moisture change; Humidity change; Network model; Fibre model; Mathematical model; Polymer; Micro-indentation; Particle composite; Interfacial debonding; Matrix cracking; Paper; Mechano-sorptive creep; Accelerated creep; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : In this thesis, the focus has been on micro-mechanical mechanisms in polymer-based materials and structures. The first part of the thesis treats length-scale effects on polymer materials. Experiments have showed that the smaller the specimen, the stronger is the material. READ MORE

  5. 3. Ageing of Asphalt Mixtures : Micro-scale and mixture morphology investigation

    Author : Prabir Kumar Das; Björn Birgisson; Nicole Kringos; Andreas Loizos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ageing; Aggregate packing; Atomic force microscopy; Asphalt mixture; Bitumen; Diffusion; Finite element analysis; Gradation; Micro-structure; Mixture morphology; Oxidative ageing; Surface ageing;

    Abstract : There are many variables that affect the viscoelastic properties of asphalt mixtures with time, among which age hardening may be considered one of the important ones. Age hardening of asphalt mixtures is an irreversible process, which contributes to a reduction of the durability of pavements and eventually increases the maintenance cost. READ MORE

  6. 4. Friction and Wear Mechanisms of Ceramic Surfaces : With Applications to Micro Motors and Hip Joint Replacements

    Author : Johanna Olofsson; Staffan Jacobson; Håkan Engqvist; Koshi Adachi; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tribology; Friction; Wear; Ceramic; Tribofilm; Alumina; Silicon nitride; Ultrasonic Motors; Hip Joint Replacement; PVD coating; Materials science; Teknisk materialvetenskap; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Abstract : Surfaces exposed to wear always transform and typically a layer of new structure and composition is formed. This layer, often called tribofilm, changes the friction and wear properties. READ MORE

  7. 5. Context-Based Micro-Training : Enhancing cybersecurity training for end-users

    Author : Joakim Kävrestad; Marcus Nohlberg; Steven Furnell; Rose-Mharie Åhlfeldt; Lothar Fritsch; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; cybersecurity; training; usable; security; user; education; awareness; Information Systems; Informationssystem IS ;

    Abstract : This research addresses the human aspect of cybersecurity by developing a method for cybersecurity training of end-users. The reason for addressing that area is that human behaviour is widely regarded as one of the most used attack vectors. READ MORE
