  1. 6. Modular Learning and Optimization for Planning of Discrete Event Systems

    Författare :Fredrik Hagebring; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete optimization; large-scale optimization; modular learning; automation; discrete event systems; active learning; Compositional optimization;

    Sammanfattning : Optimization of industrial processes, such as manufacturing cells, can have great impact on their performance. Finding optimal solutions to these large-scale systems is, however, a complex problem. They typically include multiple subsystems, and the search space generally grows exponentially with each subsystem. LÄS MER

  3. 7. Chiral Pyridine-Containing Ligands for Asymmetric Catalysis. Synthesis and Applications

    Författare :Fredrik Rahm; KTH; []
    Nyckelord :asymmetric catalysis; chiral ligand; chiral pool; oxazoline; crown ether; ditopic receptor; bipyridine; pyridyl alcohol; modular approach; P; N-ligand; diethylzinc; allylic alkylation;

    Sammanfattning : This thesis deals with the design and syntheses of chiral,enantiopure pyridinecontaining ligands and their applicationsin asymmetric catalyis.Chiral pyridyl pyrrolidine ligands and pyridyl oxazolineligands were synthesized and employed in thepalladium-catalysed allylic alkylation of 1,3-diphenyl-2-propenyl acetate with dimethyl malonate.

  4. 8. A modular mRNA approach to study and treat phospholamban mediated cardiomyopathies

    Författare :Eduarde Rohner; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In the heart, phospholamban (PLN) is a key regulator of calcium cycling through its inhibitory effect on the sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) pump. For more than two decades, modulating calcium channels has been a strong focus of prospective cardiac therapeutics with a recent emphasis on targeting PLN itself, partially due to the progressive uncovering of several cardiomyopathic PLN human mutations.

  5. 9. Cost-effective Cells for High-power Modular Multilevel Converters

    Författare :Matthijs Heuvelmans; Staffan Norrga; Hans-Peter Nee; Rik De Doncker; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MMC; modular multilevel converter; ARCP; IGCT; soft-switching; ZVS; ZCS; snubber; thyristor; SCR; silicon controlled rectifier; HVDC; STATCOM; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The modular multilevel converter (MMC) topology was introduced in 2003and has since been receiving considerable attention from industry and academia.Notable benefits compared to two- or three-level voltage source convertersare its scalability, low switching losses, low output filter requirementsand ease of adding redundancy combined with fail-safe operation.

  7. 10. Design Automation for Multidisciplinary Optimization : A High Level CAD Template Approach

    Författare :Mehdi Tarkian; Johan Ölvander; Xiaolong Feng; Fredrik Elgh; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In the design of complex engineering products it is essential to handle cross-couplings and synergies between subsystems. An emerging technique, which has the potential to considerably improve the design process, is multidisciplinary design optimization (MDO).MDO requires a concurrent and parametric design framework.
