  1. 1. Positional differences of physical peak intense periods in Swedish elite football : A pilot study of under 19 and first team players

    University essay from Gymnastik- och idrottshögskolan, GIH/Institutionen för fysisk aktivitet och hälsa

    Author : Adam Eriksson; [2024]
    Keywords : Most intense periods; Peak period; External load; Rolling avrage; Match; Official game; Positional differences; Position data; Youth soccer players; Academy players; Senior soccer players; professional soccer players; Elite players;

    Abstract : Syfte: Syftet med denna studie är att med hjälp av multivariata parametrar undersöka skillnader i fysisk extern belastning under den mest intensiva perioden (MIP) av match för spelare på ungdomselit och seniornivå samt att identifiera eventuella skillnader mellan positioner och halvlekar.Metod: En kvantitativ retrospektiv studie tillämpades, där spelare från ett seniorlag (SEN)spelandes i högsta divisionen i Sverige samt fotbollsspelare från ett ungdomselitlag (U19)från samma klubb spelades i näst högsta divisionen för åldersgruppen deltog i studien.

  3. 2. Validating and comparing Total Electron Content estimates from Incoherent Scatter Radar and Global Positioning System

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Sven Molenkamp; [2023]
    Keywords : ;

    Abstract : This thesis aims to analyze the possibilities to use Incoherent Scatter Radar to measure Total Electron Content in the ionosphere. By comparing the results from EISCATselectron density data over altitude and time to Total Electron Content estimates from GPS satellites and their receivers through a climatology as well as qualitative analysis for separate EISCAT experiments a comparison between the two is conducted.

  4. 3. Enhancing GPR Measurements using Real Time Kinematics and LiDAR Mapping

    University essay from Umeå universitet/Institutionen för fysik

    Author : Christoffer Elebro; [2022]
    Keywords : GPS; GNSS; RTK; Lidar; 3D-mapping;

    Abstract : A Ground Penetrating Radar (GPR) is a non-invasive measurement tool to locate objects in the subsurface. The GPR transmits electromagnetic waves into the ground and records the waves reflected from surface interfaces of different materials. READ MORE

  5. 4. USING N-MODULAR REDUNDANCYWITH KALMAN FILTERS FORUNDERWATER VEHICLE POSITIONESTIMATION

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Axel Enquist; [2022]
    Keywords : MATLAB; Simulink; Kalman filter; n-Modular Redundancy; Underwater;

    Abstract : Underwater navigation faces many problems with accurately estimating the absolute positionof an underwater vehicle. Neither Global Positioning system (GPS) nor Long Baseline (LBL) orShort Baseline (SBL) are possible to use for a military vehicle acting under stealth, since thesetechniques require the vehicle to be in the vicinity of a nearby ship or to surface and raise its antenna.

  6. 5. Submap Correspondences for Bathymetric SLAM Using Deep Neural Networks

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

    Author : Jiarui Tan; [2022]
    Keywords : Underwater simultaneous localization and mapping; Multibeam echosounder; Point cloud registration; Deep learning; Undervattens simultan lokalisering och kartläggning; Multibeam ekolod; Punktmolnsregistrering; Djupinlärning;

    Abstract : Underwater navigation is a key technology for exploring the oceans and exploiting their resources. For autonomous underwater vehicles (AUVs) to explore the marine environment efficiently and securely, underwater simultaneous localization and mapping (SLAM) systems are often indispensable due to the lack of the global positioning system (GPS).
