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

    University essay from Lunds universitet/Matematik LTH

    Author : Emma Jönsson; [2022]
    Keywords : Technology and Engineering;

    Abstract : 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. READ MORE

  3. 2. Fully Convolutional Networks for Mammogram Segmentation

    University essay from Linköpings universitet/Statistik och maskininlärning

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

    Abstract : 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. READ MORE

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

    University essay from Linköpings universitet/Institutionen för systemteknik

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

    Abstract : 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. READ MORE

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

    University essay from Elektroniksystem; Tekniska högskolan

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

    Abstract : 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. READ MORE
