  1. 11. Simulation and Testing of a MU-MIMO Beamforming System

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Nazyar Mehdishishavan; Zonghan Wang; [2023]
    Nyckelord :Multi-User Multiple-Input Multiple-Output MU-MIMO ; Beamforming; Sounding Reference Signal SRS ; Reciprocity-based; Butler matrix; Advanced Antenna System AAS ; Technology and Engineering;

    Sammanfattning : Multi-User Multiple-Input Multiple-Output (MU-MIMO) technology has become increasingly important in the field of wireless communication due to its ability to highly increase the capacity and efficiency of wireless networks [1]. Beamforming, as a technique used in MU-MIMO systems, improves network performance by improving signal quality and reducing interference. LÄS MER

  3. 12. Embedded digital filter design and implementation

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Xiao Su; [2023]
    Nyckelord :;

    Sammanfattning : Digital filters have been widely used in signal processing, to reduce or remove unwanted signals of different types, such as noise, and interference, and to enhance or keep desired signals. They are implemented as algorithms on an embedded system (a microcontroller) or a computer.

  4. 13. Investigation of coarse-grid CFD approach for nuclear engineering application

    Master-uppsats, KTH/Fysik

    Författare :Michela Casarella; [2023]
    Nyckelord :Thermal-hydraulics; Nuclear reactor; CFD; Sub-channel; Coarse-grid; Turbulence; Pressure drop; Termisk-hydraulik; kärnreaktor; CFD; underkanal; grovkornigt nät; turbulens; tryckfall;

    Sammanfattning : In this thesis, an innovative coarse grid CFD approach is developed that aims toexploit the capabilities of sub-channel codes and CFD methods while overcoming theirlimitations. In the approach, a very coarse mesh is implemented in the CFD softwareOpenFOAM and a new wall treatment, based on the traditional concept of the wallfunction, is applied to the wall boundary conditions of the domain to take into accountthe low resolution of the grid which does not allow to effectively capture the effect of thesolid walls on the thermo-hydraulics of the flow.

  5. 14. Hur påverkas kliniska effekter och följsamhet till behandling då flera antihypertensiva läkemedelssubstanser kombineras i en enda tablett?

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Författare :Arij Chureteh; [2023]
    Nyckelord :Hypertension; Fixed-dose combination; Single-pill combination; Medication adherence; Compliance; Adherence;

    Sammanfattning : Hypertoni är en riskfaktor för allvarliga kardiovaskulära sjukdomar. Olika läkemedelsklasser används vid behandling av hypertoni. Dessa inkluderar angiotensin omvandlade enzymhämmare, angiotensin II-receptorblockerare, kalciumkanalblockerare och tiaziddiuretika. LÄS MER

  7. 15. Elastic Net Regression for Prosthesis Control in Short Residual Limb Amputees: Performance and Generalizability

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Oskar Berg; [2023]
    Nyckelord :Neuroengineering; Statistics; Biomedical Signal Processing; Technology and Engineering;

    Sammanfattning : This Master's thesis in Biomedical Engineering investigates the performance and generalizability of linear regression models in context of prosthesis control for short residual limb amputees. This thesis uses intramuscular electromyography data, and a regression and emplys a regression technique called Elastic Net Regression - a technique that combines L1 and L2-regularization - to predict 1-DOF isometric forces outputs from fingers and the wrist.
