1. 21. Validation of a method utilising MR images for dose planning of prostate cancer treatment : Validation of new coil technology applied on the pelvis region of healthy volunteers

   Master-uppsats, Linköpings universitet/Institutionen för hälsa, medicin och vård

   Författare :Tova Rung; [2022]
   Nyckelord :Synthetic CT; Air coil;

   Sammanfattning : By generating a synthetic CT image (sCT) directly from the MRI, the electron density can be calculated, and the CT examination can be excluded from the patient flow minimizing the risk of uncertainties in the registration. Basing the radiation treatment process solely on MR images is called MRI-only and is beneficial for the patient as it can provide more accurate radiation treatment than the standardised treatment with fewer CT examinations and possibly a more cost-effective radiation treatment process.

3. 22. Detection of Pests in Agriculture Using Machine Learning

   Master-uppsats, Linköpings universitet/Institutionen för systemteknik

   Författare :Emma Olsson; [2022]
   Nyckelord :machine learning; svm; sliding window; mask r-cnn; yolov5;

   Sammanfattning : Pest inventory of a field is a way of knowing when the thresholds for pest controlis reached. It is of increasing interest to use machine learning to automate thisprocess, however, many challenges arise with detection of small insects both intraps and on plants. LÄS MER

4. 23. Stability Analysis of Hydrodynamic Performance Indicator Based on Historic Data Sets

   Master-uppsats, Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

   Författare :Canan Özel Kennedy; [2022]
   Nyckelord :Stability analysis; Anderson-Darling test; Shapiro-Wilk test; curve fitting; Q-Q plot; British Standard BS ISO 19030;

   Sammanfattning : This paper presents a stability analysis of the sensor data which is collected by QTAGG from alarge ocean going ship and using the stability results, introduces some information about howthe measurements that come from the sensors can be improved and how reliable they are. In thetheoretical part, some background information is given mainly based on British Standard(BS)ISO 19030 which was published in November, 2016. LÄS MER

5. 24. Histogram of Oriented Gradients in a Vision Transformer

   Kandidat-uppsats, Uppsala universitet/Avdelningen för visuell information och interaktion

   Författare :Jakob Malmsten; Heja Cengiz; David Lood; [2022]
   Nyckelord :vision transformer; vit; histogram of oriented gradients; hog; ai; machine learning; artificial intelligence; MNIST;

   Sammanfattning : This study aims to modify Vision Transformer (ViT) to achieve higher accuracy. ViT is a model used in computer vision to, among other things, classify images. By applying ViT to the MNIST data set, an accuracy of approximately 98% is achieved. LÄS MER

7. 25. VISUAL DETECTION OF PERSONAL PROTECTIVE EQUIPMENT & SAFETY GEAR ON INDUSTRY WORKERS

   Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

   Författare :Fredrik Strand; Jonathan Karlsson; [2022]
   Nyckelord :Machine learning; yolo; yolov4; cnn; ppe; personal protective equipment; object detection; computer vision; deep learning; artificial intelligence; ai; real-time object detection; real-time; safety; construction; workers; industry; face recognition;

   Sammanfattning : Workplace injuries are common in today's society due to a lack of adequately worn safety equipment. A system that only admits appropriately equipped personnel can be created to improve working conditions and worker safety. The goal is thus to develop a system that will improve construction workers' safety. LÄS MER
