  1. 1. Initial Orbit Determination of Resident Space Objects From A Passive Optical Imaging System: : Application to Space Situational Awareness

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Jessica McKenna; [2023]
    Keywords : Space Situational Awareness; Space Science; Angles-Only Initial Orbit Determination;

    Abstract : The probability of satellite collisions and disintegrations cluttering the near-Earth orbital environmentis ever-growing. This is especially true for the congested Low Earth Orbit (LEO) regime; once a critical density of objects is reached, a collisional cascading is projected to generate runaway growth of theorbital population.

  3. 2. Design and Construction of an Autonomous Sentry Turret Utilising Computer Vision

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Carl Bermhed; Jacob Holst; [2023]
    Keywords : Mechatronics; Arduino; Computer Vision; Stepper Motor; Airsoft; Haar Cascade; Mekatronik; Arduino; Datorseende; Stegmotor; Airsoft; Haar Cascade;

    Abstract : The design and manufacture of a sentry gun turret capable of accurately and rapidly tracking and shooting moving targets was a challenging task that required delving into various engineering disciplines. This bachelor's thesis explores this challenge by presenting the process of construction, as well as the performance results of a turret created using a combination of 3D printing, laser cutting, and metal workshop manufacturing.

  4. 3. Winter Wheat Harvest Prediction Using Primarily Satellite Radar Data from Sentinel-1

    University essay from Lunds universitet/Matematik LTH

    Author : Oliver Persson Bogdanovski; Christoffer Svenningsson; [2023]
    Keywords : Precision Agriculture; Sentinel-1 SAR; Machine Learning; Winter Wheat; Harvest Prediction; RFI-filtering; Despeckling; Mathematics and Statistics;

    Abstract : Aiding farmers with their tremendous task of sustainably and cost-efficiently feeding the world is of utmost importance. Information technology plays a crucial role in supporting farmers and supplying them with accurate information about their crops. READ MORE

  5. 4. Leveraging Posits for the Conjugate Gradient Linear Solver on an Application-Level RISC-V Core

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Mallasén Quintana; [2022]
    Keywords : Computer Arithmetic; Conjugate Gradient; Posit; IEEE-754; Floating Point; High-Performance Computing; RISC-V; Datoraritmetik; Konjugerad Gradient; Posit; IEEE-754; Flytande Punkt; Högpresterande Beräkningar; RISC-V;

    Abstract : Emerging floating-point arithmetics provide a way to optimize the execution of computationally-intensive algorithms. This is the case with scientific computational kernels such as the Conjugate Gradient (CG) linear solver. Exploring new arithmetics is of paramount importance to maximize the accuracy and timing performance of these algorithms. READ MORE

  6. 5. Validation of basal area growth functions for larch in Heureka DSS

    University essay from SLU/Southern Swedish Forest Research Centre
