  2. 2. RGB and Multispectral UAV image classification of agricultural fields using a machine learning algorithm

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Sigurbjörn Jónsson; [2019]
    Keywords : Physical Geography and Ecosystem Analysis; UAV; classification; Random Forest; Geomatics; segmentation; Earth and Environmental Sciences;

    Abstract : A common technique within image analysis is image classification which describes the process of reducing the information content of an image into few user-defined classes. With the emergence of unmanned aerial vehicles (UAVs), high spatial resolution (cm-level) images can be collected. READ MORE

  3. 3. Battery-free Visible Light Sensing

    University essay from Uppsala universitet/Avdelningen för datorteknik

    Author : Andreas Soleiman; [2019]
    Keywords : Networked embedded systems; Visible light sensing; RF backscatter; Energy harvesting;

    Abstract : In this thesis, we show that it is possible to design a battery-free light sensing system that can sense and communicate hand gestures while operating fully on harvested power from indoor light. We present two main innovations that push our system to tens of microwatts of power to enable battery-free operation. READ MORE

  4. 4. Toward Non-invasive Neonatal Gas Monitoring with Plasma-based Spectroscopy

    University essay from

    Author : Hedwig Haas; Hampus Fröjdholm; Carmen Lee; [2018]
    Keywords : plasma; sensor pad; transcutaneous; gas monitoring;

    Abstract : Transcutaneous gas monitoring of oxygen and carbon dioxide is animportant method for monitoring the oxygenation and ventilation inprematurely born infants. The amount of gas diffusing through theskin is very small and current technology rely on heating of theskin to increase the gas amount, where transcutaneous oxygenrequires the highest temperature.
