  1. 11. How Chinese - English Bilinguals Think About Time : The Effects of Language on Space-Time Mappings

    Magister-uppsats, Stockholms universitet/Centrum för tvåspråkighetsforskning

    Författare :Qiu Jun Zhang; [2020]
    Nyckelord :Linguistic relativity; Chinese - English bilinguals; mental representations of time; spatial-temporal metaphors; language experience;

    Sammanfattning : The last decades have witnessed the resurgence of research on linguistic relativity, which provides empirical evidence of possible language effects on thought across various perceptual domains. This study investigated the linguistic relativity hypothesis in the abstract domain of time by looking at how L1 Chinese - L2 English bilinguals conceptualize time in two-dimensional space. LÄS MER

  3. 12. Product structure modeling for ETO system product considering the product lifecycle : A case study of ABB Mine Hoist

    Master-uppsats, Uppsala universitet/Industriell teknik

    Författare :Sumei Zhang; [2019]
    Nyckelord :product lifecycle management PLM ; product data management PDM ; product structure management PSM ; product structure model; engineer-to-order ETO product; sales-delivery process;

    Sammanfattning : In order to gain competitive advantages in markets, companies have provided a variety of customized products to satisfy customer-specific requirements, leading to not only a large amount of product data but also high cost, long lead-time and complexity of quality control. Efficient product data management throughout the product lifecycle has become increasingly crucial, of which product structure management is regarded as the most important constituent. LÄS MER

  4. 13. Noise Analysis of Computer Chassis and Secondary Sound Source Noise Reduction

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

  5. 14. Contrast improvement of few-cycle pulses

    Magister-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Xiaoying Zhang; [2019]
    Nyckelord :;

    Sammanfattning : The intense few-cycle laser pulses play an important role in the investigations of laser-plasma interaction. However, one of the biggest challenges in their generation is the reduction of temporal intensity contrast by introducing undesired pre-pulses and a long pedestal. Two techniques were investigated in this work to improve the contrast. LÄS MER

  7. 15. Machine Learning for Inferring Sidescan Images from Bathymetry and AUV Pose

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Zitao Zhang; [2019]
    Nyckelord :;

    Sammanfattning : Underwater navigation has been a big challenge for autonomous underwater vehicles (AUVs) for a long time. It is highly dependent on acoustic methods called SONAR. There are two kinds of sonar sensors which are commonly used, the multibeam sonar and the sidescan sonar. Both of them have some advantages and limitations. LÄS MER
