  1. 1. Developing an Optimal Design for A Heart Container Operated Via Drone

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Husam Alkhatib; [2019]
    Keywords : Drone heart container; Ischemic time; Organ; Transplantation;

    Abstract : In the healthcare system when a patient is waiting for a donated heart, the choice of the transportation method is critical. Thus, the efficiency of this procedure relies on the traveling time, which could affect the ischemic time, which is the time that heart can be discharged outside the human body. READ MORE

  2. 2. Design of a UAV-based radio receiver for avalanche beacon detection using software defined radio and signal processing

    University essay from Uppsala universitet/Signaler och System

    Author : Richard Hedlund; [2019]
    Keywords : Signal processing; Software Defined Radio; Avalanche; Beacon; Antenna; SDR; DSP; Signalbehandling; Mjuvarudefinierad Radio; Lavin; Lavinsändare; Antenn; SDR; DSP;

    Abstract : A fully functional proof of concept radio receiver for detecting avalanche beacons atthe frequency 457 kHz was constructed in the work of this master thesis. The radioreceiver is intended to be mounted on an unmanned aerial vehicle (UAV or drone)and used to aid the mountain rescue teams by reducing the rescue time in findingavalanche victims carrying a transmitting beacon.

  3. 3. 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

  4. 4. Modeling and characterization of forest stands using aerial and terrestrial photogrammetry

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Simon Trcka; [2019]
    Keywords : UAV; structure from motion; remote sensing; diameter at breast height; UAS; drone; photogrammetry; forest inventory; tree height; stem volume; stand model;

    Abstract : The master ‘s thesis focused on forest inventory process based on the photogrammetric point cloud. The study deals with forest stand data collecting using terrestrial and aerial photogrammetry. READ MORE

  5. 5. Investigating the accuracy of Digital Elevation Models from UAV images in areas with low contrast : a sandy beach as a case study

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Hemin Tofiq; [2019]
    Keywords : UAV; GCP; coastal monitoring; digital elevation model; Accuracy; Earth and Environmental Sciences;

    Abstract : Elevation models are important in many applications in Geographical Information System (GIS), both when applying environmental analyses and in urban planning studies. The production of elevation models has been a difficult and expensive task using traditional surveying techniques. READ MORE
