  1. 11. Thermodynamic description of the Fe-C-Cr-Mn-Ni-O system

    Författare :Lina Kjellqvist; Malin Selleby; Bengt Hallstedt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermodynamic modelling; thermodynamic assessment; Calphad; phase diagram; spinel; compound energy formalism; ionic two-sublattice liquid model; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The Fe-C-Cr-Mn-Ni-O system is of fundamental importance when describing the influence of oxygen on high alloyed steels. Both solid and liquid phases are of great interest: The solid phases regarding oxidation processes like the formation of oxide layers, inner oxidation, sintering processes and high temperature corrosion.

  3. 12. Theoretical Developments for the Real-Time Description and Control of Nanoscale Systems

    Författare :Miroslav Hopjan; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Green’s Function; DFT; TDDFT; Hubbard Model; Many-Body Perturbation Theory; Strongly Correlated Systems; Quantum Transport; Disorder; Ehrenfest Dynamics; Electronic Friction; Exact Diagonalization; Periodic Anderson Model; Fysicumarkivet A:2018:Hopjan;

    Sammanfattning : In this thesis we focus on improvements of the description of the electron-electron correlation effects in nonequilibrium nanosystems. We mainly focus on developments of two nonequilibrium methods, namely the formalism of Nonequilibrium Green’s Function and Time Dependent Density Functional Theory and we explore the possibility to improve existing approximations in these theories.

  4. 13. A System of Systems View in Early Product Development : An Ontology-Based Approach

    Författare :Ludvig Knöös Franzén; Petter Krus; Christopher Jouannet; Ingo Staack; Kristian Amadori; Daniel DeLaurentis; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System-of-Systems; Systems Engineering; Ontology; Description Logic Reasoning; Design Space Exploration; Aircraft Design; Search and Rescue; Early Product Development;

    Sammanfattning : The concept of system-of-systems is becoming increasingly common and relevant in many engineering applications. Today’s highly interconnected world entails that more and more systems have dependencies on other systems. LÄS MER

  5. 14. Living Away from Blessings : School Failure as Lived Experience

    Författare :Carina Henriksson; Solveig Hägglund; Växjö universitet; []
    Nyckelord :school failure; lived experience; lived experience description.; temporality; spatiality; relationality; cognitive inadequacy; behavioral deficiency; the hidden curriculum; hermeneutic phenomenology; phenomenology of practice; Pedagogik; Pedagogics;

    Sammanfattning : This dissertation seeks to unveil and describe students’ experiences of school failure. Traditionally, research in the field has tended to approach school failure from a societal perspective, often construing school failure as a drop-out problem. LÄS MER

  7. 15. Shaping of Food Microstructures

    Författare :Lars Hamberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; food microstructure; flow; emulsion; carrageenan whey protein isolates; shaping; aggregate; gelatine; suspension; gel formation; particle; Fourier shape description; shape; shape measurements;

    Sammanfattning : Shape, the shaping process and the functionality of shape for food microstructure are the focus of this thesis. Shape is one of the parameters that influences the microstructure functionality; hence microstructure shape optimisation is an interesting task in the development of new functional materials and processes, especially for food, in which structure-related texture is an essential part of the product.
