  1. 26. Developing efficient industrial systems through increased integration : applications in the forest industry

    Författare :Anna Wolf; Pål Börjesson; Linköpings universitet; []
    Nyckelord :forest industry; integration; industrial ecology; energy efficiency; co-operation; biofuel; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The starting point of this work is that it is possible for an industry to increase its product value and simultaneously decrease its use of resources and production of waste material if its material and energy flows are effectively integrated into a larger system. The character and the extent of a company's environmental impact is to a large extent determined in this interaction between companies and other external actors. LÄS MER

  3. 27. Business Relationships and Integration of Information Technology

    Författare :Cecilia Lindh; Amjad Hadjikhani; Sören Kock; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integration; Business Relationships; Information Technology; Industrial organisation; administration and economics; Industriell organisation; administration och ekonomi; industriell ekonomi och organisation; Industrial Economics and Organisations;

    Sammanfattning : It is a well-established view that, over time, companies in a business-to-business setting develop long-lasting business relationships. The business relationship between two companies involves a wide range of exchanges on products, technical and economic issues. It also has a social content as it engages people in both companies.

  4. 28. Adaptive time-integration for goal-oriented and coupled problems

    Författare :Peter Meisrimel; Numerisk analys; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; time-adaptivity; goal-oriented problems; error estimation; coupled problems; waveform relaxation; asynchronous methods; conjugate heat transfer;

    Sammanfattning : We consider efficient methods for the partitioned time-integration of multiphysics problems, which commonly exhibit a multiscale behavior, requiring independent time-grids. Examples are fluid structure interaction in e.g., the simulation of blood-flow or cooling of rocket engines, or ocean-atmosphere-vegetation interaction. LÄS MER

  5. 29. “The technology is great when it works” : Maritime Technology and Human Integration on the Ship’s Bridge

    Författare :Margareta Lützhöft; Sidney Dekker; James M. Nyce; Edwin Hutchins; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; integration; man-machine-interaction; human-machine; Cognitive science; Kognitionsvetenskap;

    Sammanfattning : Several recent maritime accidents suggest that modern technology sometimes can make it difficult for mariners to navigate safely. A review of the literature also indicates that the technological remedies designed to prevent maritime accidents at times can be ineffective or counterproductive. LÄS MER

  7. 30. High order summation-by-parts methods in time and space

    Författare :Tomas Lundquist; Jan Nordström; Peter Eliasson; David A. Kopriva; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; summation-by-parts; time integration; stiff problems; weak initial conditions; high order methods; simultaneous-approximation-term; finite difference; discontinuous Galerkin; spectral methods; conservation; energy stability; complex geometries; non-conforming grid interfaces; interpolation;

    Sammanfattning : This thesis develops the methodology for solving initial boundary value problems with the use of summation-by-parts discretizations. The combination of high orders of accuracy and a systematic approach to construct provably stable boundary and interface procedures makes this methodology especially suitable for scientific computations with high demands on efficiency and robustness.
