    Abstract : Accurate knowledge of the temperature of a Permanent Magnet Synchronous Machine is of high importance, not only to ensure safe operation and improve control of the operating point, but also to avoid irreversible demagnetization of rare-earth permanent magnets. However, direct measurement using thermal sensors is not suitable for high volume and low-cost applications, due to costly sensor installation and maintenance, and therefore, the magnet temperature needs instead to be estimated.

  2. 2. Denoising of Dual Energy X-ray Absorptiometry Images and Vertebra Segmentation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Nicolas Roussel; [2018]
    Keywords : ;

    Abstract : Dual Energy X-ray Absorptiometry (DXA) is amedical imaging modality used to quantify bone mineral density and to detect fractures. It is widely used due to its cheap cost and low radiation dose, however it produces noisy images that can be difficult to interpret for a human expert or a machine. READ MORE

  3. 3. Modeling and motion control of a pick and place machine with air bearings

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Elisabeth Amann; [2012]
    Keywords : ;

    Abstract : To minimize friction related heat generation Micronic Mydata is interested in the option of using air bearings in future surface mounting machines, such as the successors of today's pick and place machine. The axes of interest is the linear motions in the horizontal plane whose objective is to place a component in the correct position on a PCB. READ MORE
