  3. 2. Visualising the Effect of Geometrical Variation in Assembled Products. Predicting Visual Quality Appearance

    Författare :Casper Wickman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tolerancing; visual quality appearance; distance perception; empirical studies; method development; visual sensitivity; and geometric variation; virtual reality;

    Sammanfattning : Today, when an industrial design concept is evaluated in an aesthetic manner, little or no consideration is given to geometrical variation, i.e. the concept is evaluated with nominal geometry. LÄS MER

  4. 3. Imaging and Treatment Outcome of Potentially Curable Prostate Cancer

    Författare :Sam Ladjevardi; Gabriel Sandblom; Christer Dahlstrand; Uppsala universitet; []

  5. 4. Downlink Resource Allocation in Cooperative Wireless Networks

    Författare :Jingya Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; precoding design; load balancing; relaying; imperfect channel state information; imperfect synchronization; Coordinated multi-point transmission; I Q imbalance; resource allocation; fractional frequency reuse;

    Sammanfattning : Wireless cooperative networks, which is based on exploiting coordination among multiple access nodes, has been considered as a promising approach to improve the spectral efficiency, reduce the energy consumption, and extend the network coverage of future wireless communication systems. In practice, the actual benefit of multi-node cooperation is affected by a variety of factors, including the quality of channel state information (CSI), the constraints on the feedback and backhaul links, hardware impairments, resource allocation and data processing schemes.

  7. 5. Positioning with supported GPS, A simulation study

    Författare :Per Hagenäs; Lars Sjöberg; KTH; []
    Nyckelord :;

    Sammanfattning : The satellite based on positioning system GPS has a very high potential in accuracy and general performance. It has also low cost, low weight and low power consumption.However, among all good proprieties there exist some bad ones. LÄS MER
