  1. 21. Characteristics of cast magnesium alloys : microstructures, defects and mechanical properties

    Författare :Haiping Cao; Anders Jarfors; Linköpings universitet; []
    Nyckelord :Mg alloys; microstructure; mechanical properties; defects; modelling; segregation bands; hot tear; mould constraint; semi-solid casting.; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Magnesium is the lightest of all structural metals. As such, and combined  with good mechanical and physical properties, it forms the basis for commercial alloys that have found successful use in a wide variety of applications. LÄS MER

  3. 22. Digital Predistortion Linearization of High Efficiency Transmitters

    Författare :Haiying Cao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : High efficiency and good linearity are two important characteristics of transmitters in future wireless communication systems. However, there is usually a trade-off: when high efficiency is achieved, linearity is degraded and nonlinear distortion occurs. LÄS MER

  4. 23. Dynamic Effects on Electron Transport in Molecular Electronic Devices

    Författare :Hui Cao; Yi Luo; Colin Lambert; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular electronics; Theoretical chemistry; Teoretisk kemi;

    Sammanfattning : HTML clipboardIn this thesis, dynamic effects on electron transport in molecular electronic devices are presented. Special attention is paid to the dynamics of atomic motions of bridged molecules, thermal motions of surrounding solvents, and many-body electron correlations in molecular junctions. LÄS MER
