  1. 1. Modelling and Optimisation of Relativistic Magnetron with Transparent Cathode : Applications for High-Power Microwaves

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :David Sawert; [2023]
    Nyckelord :Relativistic Magnetron; RM; High-Power Microwaves; HPM; Particle-in-Cell; PIC; MAGIC3D; TE11;

    Sammanfattning : This thesis aimed to investigate the relativistic magnetron (RM), which is a high-power microwave (HPM) source. Since the RM can generate high-intensity microwave radiation, it can be used as a pulsed electromagnetic weapon to target electronic systems in different objects, such as drones, missiles, or vehicles.

  3. 2. Buckling of Short End-Bearing Piles in Clay

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :David Ebenhardt; Jonas Stener; [2022]
    Nyckelord :Short piles; buckling; elastic buckling length; initial deflection; finite element method; Eurocode 3;

    Sammanfattning : Structural design of piles with respect to buckling in Sweden is commonlymade in accordance with the calculation model from the Commission ofPile Research, PKR. A prerequisite for this model is that the elasticbuckling length of the pile is shorter than the physical length. LÄS MER

  4. 3. Tree trunk image classifier : Image classification of trees using Collaboratory, Keras and TensorFlow

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för datavetenskap och medieteknik (DM)

    Författare :David Carlsson; [2020]
    Nyckelord :Barknet; TRUNK12; image classification; tree classification; tree bark classification; tree trunk classification;

    Sammanfattning : In the forestry industry tree trunks are currently classified manually. The object of this thesis is to answer whether it is possible to automate this using modern computer hardware and image-classification of tree-trunks using machine learning algorithms. LÄS MER

  5. 4. Geografisk segregering under vintertid hos rödhake (Erithacus rubecula)

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :David Ek; [2020]
    Nyckelord :Bird migration; Climate change; Erithacus rubecula; European Robin; Segregation; Wintering area;

    Sammanfattning : Segregation, that animals of different sex and/or age do not spend time together all year round, is a common phenomenon. One example is that males and older individuals in migratory birds wintering further north. Migration time also affects the distribution of birds in the wintering area. LÄS MER

  7. 5. Visual neurons with different shapes: investigation of the relationship between morphology and function

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Love Federley Ottosson; [2020]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : In this project, morphological differences between motion detector neurons in Drosophila melanogaster were compared and used to speculate regarding their function. This was achieved by comparing properties such as diameter, height, width, bifurcation, asymmetry and terminal degree. LÄS MER
