  1. 1. A First Step Towards an Algorithm for Breast Cancer Reoperation Prediction Using Machine Learning and Mammographic Images

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Emma Jönsson; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Cancer is the second leading cause of death worldwide and 30% of all cancer cases among women are breast cancer. A popular treatment is breast-conserving surgery, where only a part of the breast is surgically removed. Surgery is expensive and has a significant impact on the body, and on some women, a reoperation is needed. LÄS MER

  3. 2. Fully Convolutional Networks for Mammogram Segmentation

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Hampus Carlsson; [2019]
    Nyckelord :Mammography; FCN; Fully Convolutional Neural Networks; Mammogram Segmentation; MIAS;

    Sammanfattning : Segmentation of mammograms pertains to assigning a meaningful label to each pixel found in the image. The segmented mammogram facilitates both the function of Computer Aided Diagnosis Systems and the development of tools used by radiologists during examination. Over the years many approaches to this problem have been presented. LÄS MER

  4. 3. Techniques for High-Speed Digital Delta-Sigma Modulators

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Hsu Ching; [2016]
    Nyckelord :ASIC; Unfold; Pipeline; Higher Order; digital delta sigma modulator;

    Sammanfattning : In this theses techniques for high-speed digital delta-sigma modulator(DDSM) structures are considered. Four techniques are applied andevaluated: unfolding, increasing the number of delay elements in theinner loop, pipelining/retiming, and optimizations provided by thesynthesis tool. Of interest is to see the speed-area-power trade-offs. LÄS MER

  5. 4. Investigation of Mechanisms for Spur Generation in Fractional-N Frequency Synthesizers

    Master-uppsats, Elektroniksystem; Tekniska högskolan

    Författare :Sohail Imran Saeed; [2012]
    Nyckelord :DDSM; Digital Delta Sigma Modulator; EFM; Error Feedback Modulator; PLL Phase Locked Loop; Fractional N Frequency Synthesizer; Spur; Spurs;

    Sammanfattning : With the advances in wireless communication technology over last two decades, the use of fractional-N frequency synthesizers has increased widely in modern wireless communication applications due to their high frequency resolution and fast settling time. The performance of a fractional-N frequency synthesizer is degraded due to the presence of unwanted spurious tones (spurs) in the output spectrum. LÄS MER
