1. 1. Numerical Investigations of Incompressible Turbomachinery Applications using OpenFOAM

   Författare :Olivier Petit; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Swirling flow and unsteady phenomena are common in technical applications, such as turbines, pumps and compressors. The objective of this work is to get a good understanding of the turbulent flow features inside such applications, and to validate the computational techniques used for such applications. LÄS MER

3. 2. Towards Full Predictions of the Unsteady Incompressible Flow in Rotating Machines, Using OpenFOAM

   Författare :Olivier Petit; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulent Flow; Sliding Grid; Hydro Power; Kaplan Turbine; OpenFOAM; CFD;

   Sammanfattning : The main objective of the present work is to validatemethodologies for accurate numerical predictions of the incompressible flow ofwater in the U9 Kaplan turbine model. The term “prediction” implies that the useof detailed experimental data for boundary conditions should be avoided, andthat all important features of the studied case should be included. LÄS MER

4. 3. Design Support for e-Commerce Information Systems using Goal, Business and Process Modelling

   Författare :Ananda Edirisuriya; Paul Johannesson; Michael Petit; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Systems engineering; Systemteknik; Computer and Systems Sciences; data- och systemvetenskap;

   Sammanfattning : Enterprises use various models to find design solutions to their e-Commerce information systems. Goal, business and process models are parts of a chain of models used for this purpose. Business modelling requires structured methods to support design and traceability. LÄS MER

5. 4. Ab initio study of transition metal carbides and actinide compounds

   Författare :Weiwei Sun; Pavel Korzhavyi; Igor Di Marco; Börje Johansson; Leon Petit; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational material science; material physics; Materials Science and Engineering; Teknisk materialvetenskap;

   Sammanfattning : Two classes of materials are investigated using ab intio methods based on density functional theory. The structural properties, electronic structure and thermodynamic properties of binary and ternary transition metal carbides are discussed in details. In addition, two actinide compounds will be presented. LÄS MER

7. 5. El mito de la Quintrala : Estructuras simbólicas en dos novelas de Gustavo Frías

   Författare :Jasmin Belmar Shagulian; Débora Rottenberg; Sergio Infante; Ken Benson; Fernando Moreno Turner; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Quintrala; myth; Durand; Campbell; symbol; symbolical structure; mytheme; imaginary; Frías; Valdivieso; Vidal; Vicuña Mackenna; The Great Goddess; Diurnal Order; Nocturnal Order; figurative structuralism; Quintrala; myt; Durand; Campbell; symbol; simbolisk struktur; mytem; imaginära; Frías; Valdivieso; Vidal; Vicuña Mackenna; Stora Moder; Dagens ordning; Nattens ordning; figurativ strukturalism; Quintrala; mito; Durand; Campbell; símbolo; estructura simbólica; mitema; imaginario; Frías; Valdivieso; Petit; Vidal; Vicuña Mackenna; Gran Diosa; Régimen diurno; Régimen nocturno; estructuralismo figurativo; Spanish; spanska;

   Sammanfattning : The purpose of this comparative study is to analyse La Quintrala’s myth as a symbolic discourse, thereby filling a gap in the previous studies about La Quintrala.The theoretical and methodological framework of this analysis consists of a hermeneutical approach based on the method of figurative structuralism: mythocriticism.
