  1. 1. Contributions to Meta-Modeling Tools and Methods

    Författare :Adrian Pop; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : Highly integrated domain-specific environments are essential for the efficient design of complex physical products. However, developing such design environments is today a resource-consuming error-prone process that is largely manual. Meta-modeling and meta-programming are the key to the efficient development of such environments. LÄS MER

  3. 2. Multi-objective CFD-based design method for axial compressors

    Författare :Lars R Ellbrant; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Q3D; Turbomachinery; Design; Meta-modeling; Optimization; CFD; Validation; Compressor; Transonic;

    Sammanfattning : Economic aspects such as reducing specific fuel consumption and ever growing environmental requirements on emissions and perceived noise levels are the major incentives in the pursuit to improve aircraft engines. The overall efficiency of the engine is a combination of propulsive efficiency and thermal efficiency. LÄS MER

  4. 3. Measuring the Evolution of Automotive Software Models and Meta-Models to Support Faster Adoption of New Architectural Features

    Författare :Darko Durisic; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Modeling and meta-modeling; software measurement; automotive software architectures; software measurement;

    Sammanfattning : Background: The ever-increasing amount of software in cars today combined with high market competition demands fast adoption of new software solutions in car development projects. One challenge in enabling such a fast adoption is to develop the architecture and models of the automotive software systems in a structured and controlled way. LÄS MER

  5. 4. Tools and Methods for Analysis, Debugging, and Performance Improvement of Equation-Based Models

    Författare :Martin Sjölund; Peter Fritzson; Christoph Kessler; Walid Mohamed Taha; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Simulation; modeling; debugging; profiling; optimization; parallelism; Modelica;

    Sammanfattning : Equation-based object-oriented (EOO) modeling languages such as Modelica provide a convenient, declarative method for describing models of cyber-physical systems. Because of the ease of use of EOO languages, large and complex models can be built with limited effort. LÄS MER

  7. 5. Design and Detailed Analysis of Turbomachinery Blades using Truncated Domains

    Författare :Gonzalo Montero Villar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Evolutionary algorithms; Phase-lagged boundary conditions; Sliding grid; LODI; Stochastic optimization; Synthetic turbulence; CFD; Chorochronic;

    Sammanfattning : With the continuous growth in air traffic that we are seeing nowadays comes an increase in the requirements needed to be satisfied by an aircraft for it to be certified to fly. These stricter regulations affect aspects such as CO2 emissions, sound pollution and so on, pushing manufacturers to aim for lighter, more efficient, more robust designs. LÄS MER
