  1. 1. Innovation- och säkerhetsvetenskap : En fruktbar syntes

    Författare :Tommy Torsne; Carl Rollenhagen; Björn Wahlström; Mälardalens högskola; []

    Sammanfattning : The foundation for the thesis is a literature study within two areas: safety and innovation science. In the thesis safety science will revolve around how different methods and various models are used to identify and reduce risks, i.e. to secure the functionality within limited systems. LÄS MER

  2. 2. Optimering i organisk syntes : betingelser, system, syntesvägar

    Författare :Lars Hansson; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Optimization; Response surface method; PLS method; Silylation; Enolether; Unsaturated ketones; Diketones; Geosmin synthesis; Onepot procedure;

    Sammanfattning : This thesis deals with different optimization problems encountered in organic synthesis. The use of response surface, sequential simplex and PLS techniques, for simultanious optimization of yield and suppression of side reactions is investigated. This is illustrated by an example of enamine synthesis, were a side reaction was a serious problem. LÄS MER

    Sammanfattning : Perovskite based materials have great potentials for various energy applications and the search for new materials for uses in SOFCs has largely been concentrated to this class of compounds. In this search, we have studied perovskite phases in the system La2Co1+z(Ti1-xMgx)1-zO6, with 0  x 0.9 and z = 0.0, 0. LÄS MER

  5. 5. ForSyDe-Atom: Design of Heterogeneous Embedded Systems : Taming Complexity with Layers, Atoms and Patterns
