1. 21. Tensor Products of Highest Weight Representations and Skew-Symmetric Matrix Equations A+B+C=0

   Författare :Ida Säfström; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Highest weight respresentation; tensor product decomposition; orthogonal algebra; skew-symmetric matrix; Horn’s conjecture; moment map; coadjoint orbit; flag manifold; general linear algebra; infinite dimensional unitary representation; general linear algebra;

   Sammanfattning : The question of characterizing the eigenvalues for the sum of two Hermitian matrices, was solved in 1999, after almost a century of efforts. The saturation conjecture for GL_C(n) was proven by Knutson and Tao, filling in the last gap in Horn’s conjecture. LÄS MER

3. 22. Knowledge retention and reuse : supporting engineering decisions in simulation-driven product development

   Författare :Michael Lundin; Martin Helgoson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

   Sammanfattning : Information exchange is becoming more and more important as modern manufacturers increasingly rely on integrated product development. Research shows that designers may not be aware of existing information or be willing to disrupt their work to search for the relevant information. LÄS MER

4. 23. On the use of visualisation tools in product design : exploring possibilities and problems of virtual reality techniques

   Författare :Per Johansson; Simon Richir; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The research presented in this thesis has its base in product development methodology and examines product representations and visual displays as tools for product design. New visualisation technologies, such as VR, has entered the market, but unfortunately, questions of usability and accessibility for the designer are often set aside in favour of development of the technology itself.

5. 24. On integrated modularization in heavy-duty truck architecting

   Författare :David Williamsson; Ulf Sellgren; Anders Söderberg; Johan Malmqvist; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modularization; Module; Product Architecture; Cyber-Physical System; Machine Design; Maskinkonstruktion;

   Sammanfattning : Road transports face increasing challenges with respect to safety, legislations on lower emissions and traffic congestion, as well as numerous business challenges related to paradigm shifts in technology, tightened delivery times and cost constraints. Combination of truck electrification and automation may be utilized to address some of these issues. LÄS MER

7. 25. Integration of engineering analysis information in the product development process

   Författare :Ma Haoxue; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

   Sammanfattning : Keen competition in modern industry motivates companies to produce better products in shorter lead-time. In addition low cost is another key factor that leads commercial success of a product. In the last decade, rapid development and implementation of computer technologies have had great impact on the product development process. LÄS MER
