  1. 6. FE-Simulation of Metal Cutting Processes

    Författare :Ahmet Semih Ertürk; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal cutting; Ductile fracture; Gradient damage; Finite element method; Turning; Machining; Inverse identification;

    Sammanfattning : This thesis deals with the finite element (FE) simulation of machining processes. Realistic simulation of metal cutting processes enables a more resource-efficient machinability assessment for a given material in terms of cutting forces, chip shape and tool wear at different ranges of cutting conditions.

  2. 7. Supporting Enactment of Aspect Oriented Business Process Models : an approach to separate cross-cutting concerns in action

    Författare :Amin Jalali; Paul Johannesson; Jelena Zdravkovic; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : Coping with complexity in Information Systems and Software Engineering is an important issue in both research and industry. One strategy to deal with this complexity is through a separation of concerns, which can result in reducing the complexity, improving the re-usability, and simplifying the evolution. LÄS MER

  3. 8. Crop and weed discrimination using computer vision

    Författare :Maria Persson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Image analysis; Crops; Weeds; Other information technology; Övrig informationsteknik;

    Sammanfattning : The thesis is concerned with computer vision in ecological and precision agriculture aiming to identify crops and weeds in images of crop rows. The identification of plants can be done by extracting the plants in the image and classifying them as a crop or weed depending on the shape and color. LÄS MER

  4. 9. Performance Testing of Cutting Fluids and Tool Holders in Metal Cutting

    Författare :Varun Nayyar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chip Microstructure; Torque; Drilling; Compressed air; Turning; Tool-holding; Force.; Tapping; Keyword: Cutting Fluid;

    Sammanfattning : ABSTRACTThe metal cutting industry has evolved over the last century to the point where an increasing range and complexity of tool holding systems and cutting fluids are available for metal machining in the market. Most of the companies report their cutting fluid cost to be between 7 -17 % of the manufacturing cost. LÄS MER

  5. 10. Contributions to program- and specification-based test data generation

    Författare :Jon Edvardsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : Software testing is complex and time consuming. One way to reduce testing effort is to automatically generate test data. In the first part of this thesis we consider a framework by Gupta et al. for generating tests from programs. LÄS MER
