  1. 1. Geometry Based Design Automation : Applied to Aircraft Modelling and Optimization

    Författare :Kristian Amadori; Petter Krus; Johan Ölvander; Christopher Jouannet; Bento Silva de Mattos; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Product development processes are continuously challenged by demands for increased efficiency. As engineering products become more and more complex, efficient tools and methods for integrated and automated design are needed throughout the development process. LÄS MER

  3. 2. Efficient Image Retrieval with Statistical Color Descriptors

    Författare :Linh Viet Tran; Reiner Lenz; Björn Kruse; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; color properties; images; statistical; content-based image retrieval CBIR ; non-parametric density estimators; image database; Kernel; Gram-Schmidt; geometry-based; Information technology; Informationsteknologi;

    Sammanfattning : Color has been widely used in content-based image retrieval (CBIR) applications. In such applications the color properties of an image are usually characterized by the probability distribution of the colors in the image. LÄS MER

  4. 3. Geometry-based Radio Channel Characterization and Modeling: Parameterization, Implementation and Validation

    Författare :Meifang Zhu; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The propagation channel determines the fundamental basis of wireless communications, as well as the actual performance of practical systems. Therefore, having good channel models is a prerequisite for developing the next generation wireless systems. This thesis first investigates one of the main channel model building blocks, namely clusters. LÄS MER

  5. 4. Evolution and communication of geometry based product information within an extended enterprise

    Författare :Freddy Fuxin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : The importance of conducting efficient product development is growing steadily as traditional market boundaries diminish and are replaced by global market conditions. Digital product development builds on the foundation that digital mock-ups replace physical mock-ups, and this has the potential for strongly improving the efficiency of the product development process.
