  1. 1. Atomically Resolved ac-Mode Atomic Force Microscopy in Ultra-High Vacuum

    Författare :Lars Olsson; Franz Giessibl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : When the atomic force microscope (AFM) was invented in 1986, it was anticipated that the technique should be able to produce atomically resolved images with aquality similar to what was routinely obtained with the scanning tunnelling microscope (STM). Even though the AFM quickly became a very popular technique, the development toward ultra-high resolution imaging turned out to be slow due to problems of both fundamental and technical nature.

  2. 2. Performance analysis of a low-speed high-torque hydrostatic transmission unit

    Författare :Håkan Olsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : This thesis concerns a study of the performance of an industrial low-speed high-torque hydrostatic drive system. This type of hydrostatic transmission is commonly used in continuous operation in a wide range of heavy-duty drive applications. In many applications the transmissions have to compete with e.g. LÄS MER
