  1. 11. Data-driven Interpolation Methods Applied to Antenna System Responses : Implementation of and Benchmarking

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

    Author : Lucas Åkerstedt; [2023]
    Keywords : Model Order Reduction; Loewner Framework; State-space Representation; Nevanlinna-Pick Interpolation; Vector Fitting; Cauchy interpolation; Antenna System Responses; Benchmarking; MoM; Data-driven; Interpolation; Modelordningsreducering; Loewner Ramverk; Tillståndsrepresentation; NevanlinnaPick Interpolering; Vector Fitting; Cauchy Interpolering; Antennsystemsvar; Prestandajämförelse; MoM; Datadriven; Interpolering;

    Abstract : With the advances in the telecommunications industry, there is a need to solve the in-band full-duplex (IBFD) problem for antenna systems. One premise for solving the IBFD problem is to have strong isolation between transmitter and receiver antennas in an antenna system. READ MORE

  3. 12. Data Driven Model Identification for Remote Electrical Tilt Systems

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Raphaël Ashruf; [2023]
    Keywords : ;

    Abstract : This thesis explores the use of supervised machine learning for modelling the dynamics of Remote Electrical Tilt (RET) telecom systems. Three methodologies, including linear regressionfor linear dynamics models, Gaussian Process (GP) regression, and Recurrent Neural Networks (RNN) with Gated Recurrent Units (GRU) are proposed.

  4. 13. System Identification of a Fixed-Wing UAV Using a Prediction Error Method

    University essay from Linköpings universitet/Reglerteknik

    Author : Trulsa Eriksson; [2023]
    Keywords : System identification; Fixed-wing UAV; Modelling; Parameter estimation;

    Abstract : Unmanned aerial vehicles (UAVs) is a rapidly expanding area of research due to their versatile usage, such as inspection of places inaccessible to humans and surveillance missions. This creates a demand for a reliable model that can accurately describe the dynamics of the system in order to improve the performance of the vehicle.

  5. 14. Electron-skyrmion systems, in and out of equilibrium, and isolated or contacted to reservoirs

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Emil Adam Jonatan Östberg; [2023]
    Keywords : skyrmion; skyrmions; NEGF; freen s function; quantum transport; non-equlibrium; topology; topological charge; skyrmionics; current induced; open system; Physics and Astronomy;

    Abstract : A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. READ MORE

  6. 15. Investigating the relationship between psychological safety, well-being and performance in youth team sport athletes

    University essay from Umeå universitet/Institutionen för psykologi

    Author : Filip Myrman; Axel Lundgren; [2023]
    Keywords : psychological safety; psychological well-being; positive affect; negative affect; vitality; performance; psykologisk trygghet; psykologiskt välmående; positiv affekt; negativ affekt; vitalitet; prestation;

    Abstract : The present study aimed to investigate the linear association between psychological safety and psychological well-being, and psychological well-being and self-perceived individual and team performance in Swedish youth team sport athletes. A cross-sectional design was used, and data were collected through questionnaires of psychological safety, positive affect, negative affect, vitality, individual performance, and team performance from 131 team sport athletes (93 males, 38 females).
