1. 16. Venturing Further into the Field of 2D Materials and their Laminated Parent Phases

   Författare :Pernilla Helmer; Johanna Rosén; Jonas Björk; Martin Dahlqvist; Hannu-Pekka Komsa; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Density Functional Theory; Bonding analysis; Themodynamical stability; Electronic band structure; Computational screening; Dynamical stability; Nanolaminate; MXene; 2D material; Boridene; Chemical exfoliation; Selective etching;

   Sammanfattning : The field of 2D materials is a relatively young and rapidly growing area within materials science, which is concerned with atomically thin states of matter. Because of their intrinsic 2D morphology, 2D materials have exceptionally high surface to weight or surface to volume ratio. LÄS MER

3. 17. Det är enklare i teorin...Om skolutveckling i praktiken : En fallstudie av ett skolutvecklingsprojekt i en gymnasieskola

   Författare :Inger von Schantz Lundgren; Lars Holmstrand; Per-Erik Ellström; Ina von Schantz Lundgren; Stina Jeffner; Växjö universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Case study; school development project; implementation and complexity theory; Education; Pedagogik;

   Sammanfattning : This dissertation is a case study dealing with a school development project that took place in an upper secondary school as a result of a merger of two schools with different cultures. The project used a method called “Frirumsmodellen” and was planned to be conducted in three steps. LÄS MER

4. 18. Getting going on getting better : how is systematic quality improvement established in a healthcare organization? Implications for change management theory and practice

   Författare :Johan Thor; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Despite the widespread application of quality improvement (QI), there is enduring uncertainty about its effectiveness in healthcare as an approach to the inevitable, but challenging, task of managing organizational change. This uncertainty is due, at least in part, to our limited understanding of what it takes to apply QI fully in healthcare organizations as well as to the difficulties involved in evaluating QI efforts.

5. 19. Parameterized algorithms for hitting set variants applied to protein identification in shotgun proteomics

   Författare :Leonid Molokov; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Union Editing; Fixed Parameter Tractable; Shotgun proteomics; Hitting Set; Parameterized complexity; Hypergraph; Set Cover;

   Sammanfattning : This work is dedicated to problem of protein identification in bottom-up proteomics, and in particular, in shotgun proteomics. It is aimed on providing a new way of interpretation of peak lists. LÄS MER

7. 20. Fundamentals and logical foundations of truth maintenance

   Författare :Michael Reinfrank; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Despite their importance in AI problem solving, nonmonotonic truth maintenance systems (TMSs) still lack sufficiently well-understood logical foundations. In this thesis, I present a rigorous logical theory of TMSs. I pursue a two-step, bottom-up approach. First, I specify a direct, but implementation-independent, theory of truth maintenance. LÄS MER
