  1. 1. Classification of Atypical Femur Fracture with Deep Neural Networks

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Yupei Chen; [2019]
    Keywords : deep neural networks; classification; atypical femur fracture; class activation mapping;

    Abstract : Atypical Femur Fracture(AFF) is a type of stress fracture that occurs in conjunction with prolonged bisphosphonate treatment. In practice, AFF is very rarely identified from Normal Femur Fracture(NFF) correctly on the first diagnostic X-ray examination. READ MORE

  3. 2. Groundwater flow paths in fractured crystalline bedrock : Electromagnetic VLF measurements and modelling of a groundwater basin in Svanberga, Sweden

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Rasmus Thunell; [2018]
    Keywords : Groundwater; modelling; geophysics; comsol; VLF;

    Abstract : Sweden is a country with a relatively high number of private wells, where about 1.2 million inhabitants in permanent housing and an equal amount in summer housing relies on private wells as their drinking water supply. At the same time the market for drinking water treatment products is unregulated regarding quality and requirements are needed. READ MORE

  4. 3. The development of scanning X-ray diffraction phase mapping techniques using automated Rietveld refinements.

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Johannes Brask; [2018]
    Keywords : Retained austenite X-ray diffraction XRD Scanning X-ray diffraction SXRD; Physics and Astronomy;

    Abstract : A methodology for determining inhomogeneities in microstructural features has been established using scanning X-ray diffraction (SXRD) and automated Rietveld refinements. The method has proven successful for spatially resolved quantitative phase analysis or "phase mapping" of retained austenite on a variety of martensitic steel samples, including carbon case-hardened steel bars and quenching and partitioning (Q&P) steel sheets.

  5. 4. Multidisciplinary perspectives on a natural attenuation zone in a PCE-contaminated aquifer

    University essay from Lunds universitet/Geologiska institutionen

    Author : Robin Jansson; [2018]
    Keywords : DCIP; groundwater chemistry; Tetrachlorethene; PCE; natural attenuation; Earth and Environmental Sciences;

    Abstract : The old dry-cleaner in Hagfors, is one of the most seriously tetrachloroethene (PCE) contaminated sites in Sweden. Ever since the pollution was discovered in the groundwater in the 1990s, the site has undergone remedi-ation two times with limited success. READ MORE

  6. 5. Comparison of Photogrammetry Interpretation with Physical Structural Field Measurements

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Fredrik Osterman; [2017]
    Keywords : Fracture mapping; photogrammetry; 3D-modelling; rock classification; field safety; Sprickkartering; fotogrammetri; 3D-modellering; bergklassificering; säkerhet i fält;

    Abstract : Fracture mapping of bedrock and knowledge about how fractures influence rock strength and stability is of great importance in a constructional context. These factors largely dictate where one can build and not build in rock, and to what extent reinforcements and safety measurements are needed. READ MORE
