  1. 1. Study of AI Service Providers in IT Consulting, Marketing, and Law

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Aren Hovsepyan; Kevin Johansson; [2023]
    Nyckelord :Artificial Intelligence; AI; professional service firms PSFs ; AI services; IT consulting; marketing; legal services; Gioia analysis; sector-specific analysis of AI services; automation; augmentation; intermediaries; Artificiell intelligens; AI; professionella tjänsteföretag PSFs ; AI-tjänster; IT-rådgivning; marknadsföring; juridiska tjänster; Gioia analys; sektorspecifik analys av AI-tjänster; automatisering; augmentation; mellanhänder;

    Sammanfattning : This study employs a Gioia analysis to investigate the AI services offered within three distinct professional service sectors in Sweden: IT consulting, marketing, and legal services. Utilizing a list of companies from a prior KTH project and publicly accessible information, we applied a cross-sectoral Gioia analysis to systematically categorize, compare, and understand the types of AI services provided and how these offerings differ between sectors.

  3. 2. Classification and localization of extreme outliers in computer vision tasks in surveillance scenarios

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Tariq Daoud; Emanuel Zere Goitom; [2022]
    Nyckelord :Computer vision; deep learning; machine learning; artificial neural networks; convolutional neural networks; YOLOv4; Datorseende; djupinlärning; maskininlärning; artificiella neurala nätverk; konvolutionella neurala nätverk; YOLOv4;

    Sammanfattning : Convolutional neural networks (CNN) have come a long way and can be trained toclassify many of the objects around us. Despite this, researchers do not fullyunderstand how CNN models learn features (edges, shapes, contours, etc.) fromdata. LÄS MER

  4. 3. Noise Reduction of Scintillation Camera Images Using UNET: A Monte Carlo Simulation Approach

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Johanna Korpijärvi; [2021]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background The project aims to reduce the noise in planar 111-In projections with a machine learning model. Method Sixteen base phantoms were used to create 696 phantoms in XCAT. An anterior planar projection was simulated with 111-In and ten uptake curves for each phantom in SIMIND. LÄS MER

  5. 4. Networked Model Predictive Control for Satellite Formation Flying

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Damiana Catanoso; [2019]
    Nyckelord :Satellite Formation Flying; Model Predictive Control;

    Sammanfattning : A novel continuous low-thrust fuel-efficient model predictive control strategy for multi-satellite formations flying in low earth orbit is presented. State prediction relies on a full nonlinear relative motion model, based on quasi-nonsingular relative orbital elements, including earth oblateness effects and, through state augmentation, differential drag.

  7. 5. Analysis of Passive Attitude Stabilisation and Deorbiting of Satellites in Low Earth Orbit

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Benjamin Hawe; [2016]
    Nyckelord :electrodynamic; electrodynamic tether; EDT; drag augmentation; drag sail; drag balloon; passive attitude stabilisation; passive; attitude; stability; low earth orbit; LEO; deorbit; de-orbit; Post Mission Disposal; TeSeR;

    Sammanfattning : Orbital debris poses a serious threat to ongoing operations in space.  Recognising this threat, the European Commission has funded the three-year Technology for Self Removal (TeSeR) project with the goal of developing a standard scalable Post Mission Disposal (PMD) module to remove satellites from orbit following the completion of their mission.
