  1. 6. Compact Radar System

    University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Author : Nikhil Chalikonda; Naga Viswanth Bonthu; [2022]
    Keywords : ;

    Abstract : Context: Radar was developed in secret during world war II to detectobstacles or any incoming threat. The term radar was coined in 1940by United States Military as an acronym for "Radio Detection andRanging". Using radio waves a radar detects any incoming threat orobstacle [10]. The basic purpose of radar is for monitoring and security. READ MORE

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

    Author : Lukas Bähner; [2022]
    Keywords : plasma; fusion; ICRH; Ion Cyclotron Resonance Heating; RF; radio frequency; Fokker-Planck equation; Fokker-Planck solver; quasilinear operator; Coulomb collision; Doppler shift; velocity distribution; local temperature; plasma; fusion; ICRH; joncyklotronuppvärmning; RF; radiofrekvens; Fokker-Planck-ekvationen; Fokker-Planck-lösare; kvasilinjär operator; Coulombkollisioner; Dopplerskift; hastighetsfördelning; lokal temperatur;

    Abstract : The goal of nuclear fusion research is to create a clean and virtually limitless energy source. In order to that, a plasma must be heated to hundreds of millions degrees Celsius. A commonly used heating mechanism is ion cyclotron resonance heating, where antennas emit radio waves into the plasma. READ MORE

  4. 8. Reconstruction of the energy of neutrinos with neural networks: Event-by-event uncertainty estimation

    University essay from Uppsala universitet/Högenergifysik

    Author : Ting Wing CHOI; [2022]
    Keywords : ;

    Abstract : When high-energy neutrinos interact with matter, radio waves will be emitted. Radio detectionallows us to measure UHE(> 1016eV) neutrinos by instrumenting a huge volume with a sparsearray of radio antenna stations at a low cost. READ MORE

    Keywords : CNN; SVM; DBScan; MIMO; Bandwidth; frequencies; human presence detection; CNN; SVM; DBScan; MIMO; Bandbredd; frekvenser; mänsklig närvaro detektering;

    Abstract : Wireless communication equipment is widely available and the number of transmitters and receivers keeps increasing. In addition to communications, wireless nodes can be used for sensing. READ MORE

  6. 10. Measuring the [C II]-to-H I connection in high-redshift absorption-selected galaxies

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Gaurav Senthil Kumar; [2022]
    Keywords : QSO; Quasar; Black Hole; AGN; Active Galactic Nuclei; DLA; Damped Lyman Alpha; C II; [C II]; H I; Sightline; HST; X-shooter; Spectroscopy; Echelle Spectroscope; Hyperfine transition; Hyperfine; Physics and Astronomy;

    Abstract : HI neutral gas is the basic building block of galaxies. It dictates the star formation rate and hence the metal enrichment rates within high redshift galaxies. HI neutral gas cannot be directly observed beyond z ≈ 0. READ MORE
