26. Pressure-Induced Amorphization and Distinct Amorphous States of Clathrate Hydrates
Sammanfattning : This thesis summarizes a study on the pressure-induced amorphization (PIA) and structures of amorphous states of clathrate hydrates (CHs).PIA involves the transition of a crystalline material into an amorphous solid in response of mechanical compression at temperatures well below the melting point.

27. Synthesis and Characterization of ZnO Nanostructures
Sammanfattning : One-dimensional ZnO nanostructures have great potential applications in the fields of optoelectronic and sensor devices. Therefore, it is very important to realize the controllable growth of one-dimensional ZnO nanostructures and investigate their properties. LÄS MER
28. Förskollärare planerar barns möten med matematik : Ett reflektivt skoldidaktiskt perspektiv
Sammanfattning : Licentiatavhandlingen riktar blicken mot planeringsarbete i förskolan. Syftet är att beskriva och analysera förskollärares autentiska planering av barns möten med matematik. Studiens teoretiska inramning utgörs av den reflektiva skoldidaktiska teorin som betonar, oavsett skolform, lärares ansvarstagande för undervisning. LÄS MER
29. Development and Application of a First Principle Molecular Model for Solvent Effects
Sammanfattning : A considerable part of chemistry in nature and industry, takes place in an environment of other molecules. Reactions, transitions, interactions or other chemical processes are almost always modified by the environment. LÄS MER
30. Cognition reversed : Robot learning from demonstration
Sammanfattning : The work presented in this thesis investigates techniques for learning from demonstration (LFD). LFD is a well established approach to robot learning, where a teacher demonstrates a behavior to a robot pupil. This thesis focuses on LFD where a human teacher demonstrates a behavior by controlling the robot via teleoperation. LÄS MER
