  1. 1. Visual Bird's-Eye View Object Detection for Autonomous Driving

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Erik Lidman; [2023]
    Nyckelord :computer vision; machine learning; neural networks; deep learning; autonomous driving; autonomous systems; datorseende; maskininlärning; neuronnät; djupinlärning; autonom körning; autonoma system;

    Sammanfattning : In the field of autonomous driving a common scenario is to apply deep learningmodels on camera feeds to provide information about the surroundings. A recenttrend is for such vision-based methods to be centralized, in that they fuse imagesfrom all cameras in one big model for a single comprehensive output. LÄS MER

  2. 2. Stochastic Frank-Wolfe Algorithm : Uniform Sampling Without Replacement

    Master-uppsats, Umeå universitet/Institutionen för matematik och matematisk statistik

    Författare :Olof Håkman; [2023]
    Nyckelord :Stochastic Frank-Wolfe; Stochastic optimization; Sampling without replacement;

    Sammanfattning : The Frank-Wolfe (FW) optimization algorithm, due to its projection free property, has gained popularity in recent years with typical application within the field of machine learning. In the stochastic setting, it is still relatively understudied in comparison to the more expensive projected method of Stochastic Gradient Descent (SGD). LÄS MER

  3. 3. Hematologiska förändringar hos hund efter behandling med kliniska doser av prednisolon

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Clinical Sciences

    Författare :Linda Daly; [2020]
    Nyckelord :prednisolon; glukokortikoid; hematologiska förändringar; hund;

    Sammanfattning : Glukokortikoider används frekvent inom veterinärmedicin tack vare sina antiinflammatoriska och immunsupprimerande egenskaper. Generella indikationer till behandling med glukokortikoider är bland annat allergier, immunmedierade sjukdomar, neoplastiska sjukdomar och som ersättningsterapi vid hypoadrenokortisism. LÄS MER

  4. 4. Stratification, Sampling and Estimation: Finding the best design for the Swedish Investment Survey

    Kandidat-uppsats, Statistiska institutionen

    Författare :Linda Wiese; [2013]
    Nyckelord :sampling design; stratified simple random sampling without replacement STSRS ; probability proportional to size without replacement; Neyman allocation; Horvitz-Thompson estimation; generalised regression estimation GREG ; standard deviation; Swedish Investment Survey;

    Sammanfattning : In this thesis, different methods are used to investigate the best design for the Swedish Investment Survey. The methods used today are stratify on number of employees, Neyman-allocation, STSRS-sampling and HT-estimation. The alternative methods in this thesis are stratify on turnover, -sampling and GREG-estimation. LÄS MER

  5. 5. Implementation of a fast method for reconstruction of ISAR images

    Uppsats för yrkesexamina på grundnivå, Bildbehandling; Tekniska högskolan

    Författare :Niklas Dahlbäck; [2003]
    Nyckelord :Technology; radar; RCS; radar cross section; ISAR; image reconstruction; algorithm; FFT; TEKNIKVETENSKAP;

    Sammanfattning : By analyzing ISAR images, the characteristics of military platforms with respect to radar visibility can be evaluated. The method, which is based on the Discrete-Time Fourier Transform (DTFT), that is currently used to calculate the ISAR images requires large computations efforts. LÄS MER
