  1. 36. Dynamics of a CRAFT : A simulation study on a Counter Rotating vertical Axis Floating Tilting wind turbine

    University essay from Uppsala universitet/Elektricitetslära

    Author : Benjamin Hedlund Peters; Linda Goude; [2023]
    Keywords : wind power; counter rotating; contra rotating; offshore wind; floating wind power; vertical axis wind turbine; VAWT; renewable energy;

    Abstract : In this thesis the Counter Rotating vertical Axis Floating Tilting wind turbine (CRAFT) has been explored by creating a simulation model in the program Simulink. The CRAFT prototype is a new type of wind turbine under development by World Wide Wind and Uppsala University with the aim to produce a large scale floating vertical axis wind turbine (VAWT) with two cone shaped counter rotating turbines.

  3. 37. Numerical simulations of ultrafast dynamics in plasmonic nanostructures

    University essay from Umeå universitet/Institutionen för fysik

    Author : Nils Henriksson; [2023]
    Keywords : Ultrafast nanophotonics; Three temperature model; Numerical simulations;

    Abstract : Plasmonic effects in nanosized particles enhance the interaction between light and matter due to the localized surface plasmon resonance, with potential applications such as all-optical transistors and optical computers. Commonly, the dynamics of nanoparticles’ optical properties are assessed via pump-probe spectroscopy, where a plasmonic structure is exited by an initial laser, the pump. READ MORE

  4. 38. Improving Image Stabilization in Modern Surveillance Cameras

    University essay from Lunds universitet/Matematik LTH

    Author : Emil Manelius; [2023]
    Keywords : Image stabilization; Technology and Engineering;

    Abstract : This thesis investigates potential ways to improve the image stabilization in Axis Communications surveillance cameras. The current in-house developed stabilization algorithm, Axis EIS, stabilizes based on gyroscope measurements. READ MORE

  5. 39. Real time non-invasive estimation of oxygen uptake using smartphones

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Arvid Lund; [2023]
    Keywords : Oxygen uptake; Acceleration; Smartphone; Estimation; Health; Technology and Engineering;

    Abstract : Oxygen uptake is a great indicator of cardiopulmonary health but requires spe- cialized equipment and is time consuming to measure. There are ways to estimate oxygen uptake based on other factors such as heart rate and acceleration. READ MORE

  6. 40. Alignment of Image Sensor using Piezoelectric Crystals

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Julia Jakobsson; Reem Chahrour Muhieddine; [2023]
    Keywords : piezo; piezoelectric; crystal; piezoelectric crystal; piezoelektrisk; kristall; piezoelektrisk kristall; camera; kamera; focus; fokus; Axis; Axis Communications; alignment; justering; prototyp; prototype; algorithm; algoritm; Technology and Engineering;

    Abstract : The use of piezoelectric crystals as a way to achieve automatic alignment of an image sensor in a camera was investigated in collaboration with Axis Communications AB. Piezoelectric crystals can be created into different configurations, piezoelectric stacks being one of the simpler ones. READ MORE
