  1. 1. Theoretical prediction of properties of atomistic systems : Density functional theory and machine learning

    Författare :Alexander Lindmaa; Rickard Armiento; Igor Abrikosov; Torbjörn Björkman; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The prediction of ground state properties of atomistic systems is of vital importance in technological advances as well as in the physical sciences. Fundamentally, these predictions are based on a quantum-mechanical description of many-electron systems. LÄS MER

    Sammanfattning : Biopolymers, which are produced from natural sources, are gaining interest as a potential replacement for fossil-based polymers. As such, they are already widely used in several industries, including the food, healthcare, and personal care industries. LÄS MER

  7. 5. Gifting Technologies : Ethnographic Studies of End-users and Social Media Sharing

    Författare :Jörgen Skågeby; Vivian Vimarlund; Malin Sveningsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sociala medier; virtuell etnografi; fildelning; gåvor; Computer science; Datavetenskap;

    Sammanfattning : This thesis explores what dimensions that can be used to describe and compare the sociotechnical practice of content contribution in online sharing networks. Data was collected through online ethnographical methods, focusing on end-users in three large media sharing networks. LÄS MER
