1. 1. Image analysis tool for geometric variations of the jugular veins in ultrasonic sequences : Development and evaluation

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

   Författare :Arvid Westlund; [2018]
   Nyckelord :active contour; ultra sound; ultrasonic; image analysis; internal jugular veins; snake;

   Sammanfattning : The aim of this project is to develop and perform a first evaluation of a software, based on the active contour, which automatically computes the cross-section area of the internal jugular veins through a sequence of 90 ultrasound images. The software is intended to be useful in future research in the field of intra cranial pressure and its associated diseases. LÄS MER

3. 2. Efficient Energy Transfer for Wireless Devices

   Kandidat-uppsats, Fasta tillståndets elektronik

   Författare :Arvid Westlund; Oskar Bernberg; [2012]
   Nyckelord :Voltage regulator;

   Sammanfattning : This project is intended to findsuitable circuit architecture forefficient power transmission where thepower supply is low.Two circuits will be built. The firstwill receive high AC which correspondsto the voltage created in a piezoelement once subjected to stress fromfoot steps It will deliver 3.3DC. LÄS MER
