  1. 1. Collaborative Mapping with Drone Swarms Utilizing Relative Distance Measurements

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Johan Forsman; Carl Tidén; [2023]
    Nyckelord :;

    Sammanfattning : The field of use for unmanned aerial vehicles, UAVs, has completely exploded in the last decade. Today they are used for surveillance missions and inspecting places that are difficult for people to access. To increase the efficiency and robustness in the execution of these types of missions, swarms of cooperating drones can be used. LÄS MER

  3. 2. Multi-Scale Topology Optimization of Lattice Structures Using Machine Learning

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

    Författare :Julia Ibstedt; [2023]
    Nyckelord :Topology optimization; Multi-scale topology optimization; Machine learning; Gaussian process; Homogenization; Inverse homogenization; Anisotropic materials; Symmetry groups; Material property space; Topologioptimering; Flerskalig topologioptimering; Maskininlärning; Gaussian process; Homogenisering; Anisotropa material; Symmetrigrupper; Materialegenskapsrymd;

    Sammanfattning : This thesis explores using multi-scale topology optimization (TO) by utilizing inverse homogenization to automate the adjustment of each unit-cell's geometry and placement in a lattice structure within a pressure vessel (the design domain) to achieve desired structural properties. The aim is to find the optimal material distribution within the design domain as well as desired material properties at each discretized element and use machine learning (ML) to map microstructures with corresponding prescribed effective properties.

  4. 3. ”Och med granskogen följer mörker” Natursyn i två barnlitterära bilderböcker av Lars Lerin

    Kandidat-uppsats, Göteborgs universitet/Institutionen för litteratur, idéhistoria och religion

    Författare :Oskar Jonsson; [2022-02-17]
    Nyckelord :Lars Lerin; Ekokritik; Barn- och ungdomslitteratur; Bilderböcker;

    Sammanfattning : This thesis examines which attitudes towards nature can be found in two contemporary children’s picture books by Swedish artist and author Lars Lerin. The questions posed further concern whether there are visible differences between the attitudes in the two books and whether there is a didactic attempt to influence the reader in a certain direction.

  5. 4. Simple RSRP Fingerprint Collection Setup and Indoor Positioning in 5G

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Sofi Flink; Annie Tallund; [2022]
    Nyckelord :5G; indoor positioning; radio fingerprint; k nearest neighbor; naive bayes; automated data collection; Technology and Engineering;

    Sammanfattning : Solving for a way to accurately predict the position of a user equipment is crucial in an array of applications within 5G new radio. One approach is to form unique identifiers, also known as fingerprints, and map them to positional data in an area. LÄS MER

  7. 5. Dynamical Behaviors of A Class of Generalized Skew Shifts

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Kuan Yan; [2022]
    Nyckelord :mathematics; dynamical systems; skew shifts; SNAs; matematik; dynamiska system; skeva skift; SNAs;

    Sammanfattning : In this paper we study a dynamical system given by a variant of the classic skew-shifts on the torus $S^1\times S^1$. Our map is defined based on $T(x,y) = (x+\omega,x+f(y))$, where $\omega$ is Diophatine, $f$ is an orientation-preserving circle diffeomorphism. LÄS MER
