  1. 1. Coverage Motion Planning for Search and Rescue Missions : A Costmap Based Approach for fixed wing UAVs using Simulated Annealing &Cubic Splines

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Fredrik Rönnkvist; [2023]
    Nyckelord :Motion planning; Path planning; Cubic splines; Coverage path planning.;

    Sammanfattning : The present study proposes a novel approach to Coverage Path Planning for unmanned aerial vehicle (UAV) inspired by the Orienteering Problem. The main goal is to develop an algorithm suitable for Search and Rescue Missions, which can produce a search pattern with dynamical constrains, that is not limited to the traditional back-and-forth motion or spiral patterns.

  3. 2. Compact Digital Track Maps: Enhancing Train Traveller Information at the Crossing of Accuracy and Availability : A comparative analysis of algorithms for generating compact representations of railway tracks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Adam Andersson; [2023]
    Nyckelord :Train positioning; Digital track map; Digital map generation; Position measurement; Global navigation satellite system; Cartography; Tågpositionering; Digitala spårkartor; Generering av digitala kartor; Positionsmätning; Satellitnavigation; Kartograf;

    Sammanfattning : Trains are constrained to the railway tracks they operate on. This can be leveraged for absolute train positioning, where a train’s position can be mapped onto a digital track map (DTM). Extensive research has been dedicated to enhancing the accuracy of DTMs. LÄS MER

  4. 3. A mixed clinicopathological and molecular proxy of homologous recombination deficiency in triple negative breast cancer

    Master-uppsats, Lunds universitet/Examensarbeten i bioinformatik

    Författare :Elise Walford; [2021]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : Clinical models are increasingly employed in medical science as either diagnostic or prognostic aids. Machine-learning methods are able to draw links in large data that can be used to predict patient risk and allow more informed decisions regarding treatment and medication intervention. LÄS MER

  5. 4. Machine learning methods for seasonal allergic rhinitis studies

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Zijie Feng; [2021]
    Nyckelord :Machine learning; Seasonal allergic rhinitis; Random forest; Partial least squares discriminant analysis; Bootstrap; Cubic smoothing splines; Single-cell RNA sequencing;

    Sammanfattning : Seasonal allergic rhinitis (SAR) is a disease caused by allergens from both environmental and genetic factors. Some researchers have studied the SAR based on traditional genetic methodologies. As technology develops, a new technique called single-cell RNA sequencing (scRNA-seq) is developed, which can generate high-dimension data. LÄS MER

  7. 5. Periodic and Non-Periodic Filter Structures in Lasers

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Leo Enge; [2020]
    Nyckelord :Laser; Grating Filters; Perturbation Theory; WKB Approximation; Bi-cubic Splines; Laser; optiska filter; störningsteori; WKB-approximation; bi-kubiska splines;

    Sammanfattning : Communication using fiber optics is an integral part of modern societies and one of the most important parts of this is the grating filter of a laser. In this report we introduce both the periodic and the non-periodic grating filter and discuss how there can be resonance in these structures. LÄS MER
