  1. 11. Influence of non-dipole transitions on the extraction of EMCD

    University essay from Uppsala universitet/Materialteori

    Author : Paul Michel Zeiger; [2019]
    Keywords : ;

    Abstract : ELNES-spectra of the L3 and L2-edge of bcc-iron are simulated using a Bloch wave method for the calculation of the DDSCS within a 1st-order Born approximation of the inelastic electron scattering process in order to study the influence of non-dipole terms on the EMCD-signal. The necessary electronic structure information is obtained from a DFT-calculation using WIEN2k. READ MORE

  3. 12. Automatic Feature Extraction for Human Activity Recognitionon the Edge

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

    Author : Oscar Cleve; Sara Gustafsson; [2019]
    Keywords : Human Activity Recognition; Automatic Feature Extraction; Automatic Feature Selection; Automated Machine Learning; Random Forest Classifier; Hypothesis Test;

    Abstract : This thesis evaluates two methods for automatic feature extraction to classify the accelerometer data of periodic and sporadic human activities. The first method selects features using individual hypothesis tests and the second one is using a random forest classifier as an embedded feature selector. READ MORE

  4. 13. Tracking of railroads for autonomous guidance of UAVs : using Vanishing Point detection

    University essay from KTH/Mekatronik

    Author : Anthony Clerc; [2018]
    Keywords : Railroad tracking; Autonomous guidance UAV; Railroad topology; Vanishing point detection; Gabor filters; Edge detection;

    Abstract : UAVs have gained in popularity and the number of applications has soared over the past years, ranging from leisure to commercial activities. This thesis is discussing specifically railroad applications, which is a domain rarely explored. Two different aspects are analysed. READ MORE

  5. 14. On the development of an unsupervised probabilistic algorithm for grayscale fluorescence image segmentation

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Magnus Brander; [2018]
    Keywords : bayesian decision theory; bayesian; image segmentation; fluorescence microscopy images; Otsu; Physics and Astronomy;

    Abstract : In the field of computational biology, fluorescence microscopy images often constitute the input source of information. The process of binarization of raw images to delineate interesting objects requires image segmentation into signal and background pixels. READ MORE

  6. 15. Machine Vision Inspection of the Lapping Process in the Production of Mass Impregnated High Voltage Cables

    University essay from Blekinge Tekniska Högskola

    Author : Jim Nilsson; Peter Valtersson; [2018]
    Keywords : Computer Vision; Edge Extraction; Industrial Metrology; Projection Profile; Peak Detection;

    Abstract : Background. Mass impregnated high voltage cables are used in, for example, submarine electric power transmission. One of the production steps of such cables is the lapping process in which several hundred layers of special purpose paper are wrapped around the conductor of the cable. READ MORE
