1. 21. Thermal Imaging Platform for Drones : Cost-effective localization of forest fires

   University essay from Uppsala universitet/Institutionen för teknikvetenskaper

   Author : Joel Bjervig; Johan Slagbrand; [2019]
   Keywords : Thermal; thermal camera; forest fire; forest fires; fire; fires; raspberry pi; drones; drone;

   Abstract : A device for identifying forest fires in an early stage has been developed during the course of this project. Attached to a drone, this prototype will provide a live-stream to a web server displaying a blended frame, made of a thermographic image showing thermal radiation and a regular photography with the visible light.

3. 22. Improving Image Quality in Cardiac Computed Tomography using Deep Learning

   University essay from Linköpings universitet/Avdelningen för kardiovaskulär medicin

   Author : David Wajngot; [2019]
   Keywords : deep learning; neural network; GAN; cycleGAN; CT; heart; imaging; medical imaging;

   Abstract : Cardiovascular diseases are the largest mortality factor globally, and early diagnosis is essential for a proper medical response. Cardiac computed tomography can be used to acquire images for their diagnosis, but without radiation dose reduction the radiation emitted to the patient becomes a significant risk factor. READ MORE

4. 23. Simulation of Hardening of the MahanaKhon Tower Mat Foundation

   University essay from KTH/Betongbyggnad

   Author : Zakaria Kazi-tani; [2019]
   Keywords : Hydration; MahanaKhon tower; mat foundation; young concrete; temperature development; thermal stresses; cracking; fly ash; finite element analysis; COMSOL Multiphysics; Hydratation; MahanaKhon tower; bottenplatta; ung betong; temperaturutveckling; termiska spänningar; sprickbildning; flygaska; finita elementanalys; COMSOL Multiphysics;

   Abstract : Cement hydration is the result of a series of simultaneous chemical reactions occurring during the production of concrete. An excessive amount of heat is generated, which consequently may give rise to thermal stresses and cause early age cracks in concrete that may affect its structural integrity, and load bearing capacity.

5. 24. Impact of environmental variables on tundra vegetation onset of flowering explained by survival modelling

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Hanna Jonsson; [2019]
   Keywords : Flowering; Phenology; Cox proportional hazard model; Tundra; International tundra experiment; Climate change; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

   Abstract : Timing of phenological events are highly related to climate and is one of the first signs of ecosystem responses to the climate change. Timing of flowering phenology is an important trait influencing the distribution and fitness of plants species. READ MORE

6. 25. Needle Navigation for Image Guided Brachytherapy of Gynecologic Cancer

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

   Author : Alireza Mehrtash; [2019]
   Keywords : Image Guided Surgery; Surgical Navigation System; Needle Navigation system; Brachytherapy; MRI; 3D Slicer;

   Abstract : In the past twenty years, the combination of the advances in medical imaging technologies and therapeutic methods had a great impact in developing minimally invasive interventional procedures. Although the use of medical imaging for the surgery and therapy guidance dates back to the early days of x-ray discovery, there is an increasing evidence in using the new imaging modalities such as computed tomography (CT), magnetic reso- nance imaging (MRI) and ultrasound in the operating rooms.
