  2. 1. Truth and Proof in the Long Run: Essays on Trial and-Error Logics

    Author : Martin Kaså; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; convergence; dynamic meaning; experimental logics; knowable consistency; tableaux systems; trial-and-error;

    Abstract : The theme of this book is convergence. For many philosophical representations of the evolution of theories, as well as representations of the meaning of the language used to express these theories, it has been essential that there exists some kind of convergence. READ MORE

  4. 2. Computational Materials Design of Medium Mn Steels

    Author : Fei Huyan; Annika Borgenstam; Peter Hedström; Marcel Somers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Medium Mn steels (~ 3–10 mass % Mn), a new category of advanced high strength steels, attracted worldwide research interests recent years due to their excellent mechanical properties and low cost. These steels have fine microstructures and contain large fraction of metastable retained austenite (~ 30 volume %), therefore exhibit excellent strength and elongation. READ MORE

  5. 3. A critic in action? A functional examination of the Striato-Pallido-Habenular circuit

    Author : Moritz Weglage; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The basal ganglia (BG) and the midbrain dopamine (DA) system are considered key loci of reinforcement learning (RL), or learning by "trial and error", in the brain. The BG are implicated in action selection, and thus the "trial" part of the learning process, and the dopamine (DA) system is known to encode "error" signals. READ MORE

  6. 4. Design optimisation of aeroengine compressor blades

    Author : Jörgen Burman; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Optimisation of multistage axial compressors is a time-demanding challenge in large need of effective methods. Traditionally, the design has been based on "trial-and-error" procedures, which count on the skills and experience of the designer to suggest redesigns that are likely to yield improvements.

  7. 5. Comparability of Railway Rail Steels Low Cycle Fatigue Behaviour

    Author : Martin Schilke; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway rail steel; strain energy density; Low cycle fatigue;

    Abstract : Several different kinds of steel are used for railway rails. From simple pearlitic steels for rarely used tracks over premium pearlitic steels for high performance lines to special bainitic, martensitic and austenitic steels for switches and crossings. Most of these steels have been trial and error developed over time in track. READ MORE
