  1. 1. Parabolic equation models simulating LoS MIMO conditions

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Zarafshan Carneil; [2023]
    Nyckelord :MIMO; channel capacity; phase difference; MIMO phase;

    Sammanfattning : This thesis explores and develops a simulation model for Line of Sight(LoS) Multiple-Input Multiple-Output (MIMO) systems in complex environments. The focus will be on implementing a 2 × 2-MIMO system in order to study phase differences of the received signals. LÄS MER

    Nyckelord :UF-Entreprenörskap; Entreprenörskap; Pedagogik kreativitet.;

    Sammanfattning : This thesis first and foremost investigates how entrepreneurial teachers today work with teachingcreativity to young entrepreneurs, at upper secondary level in Sweden. To then come toconclusions on how to improve and developed teaching of creativity in young entrepreneurs. Forthat purpose, this thesis, has the following research questions. LÄS MER

  4. 3. Simulation of Quantum Cascade Lasers

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Författare :Zakaria Mohamed; [2023]
    Nyckelord :Quantum Cascade Lasers; Simulations; Numerical Methods; Computational Models; Heterostructures; Physics and Astronomy;

    Sammanfattning : This thesis aimed to contribute to the improvement of Quantum Cascade Lasers (QCLs) by focusing on the effective determination of quantum levels in these devices. The current method relies on an outdated Fortran code, which poses challenges when integrating into optimization schemes. LÄS MER

  5. 4. Innehållets vara eller icke vara : En studie om urvalet av kontroversiella ämnen i samhällskunskap

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Petter Herlogsson; [2023]
    Nyckelord :Samhällskunskap; kontroversiella ämnen; urval; skolattacker;

    Sammanfattning : This study begins with a presentation of civics teachers’ free space in their selection of topics regarding their daily lectures with their students. The study also presents a new view on Swedish school systems, where an increased threat level, perceived or real, is always present. LÄS MER

  7. 5. Experimental Study of Installation Effects on Cooling Fan Noise

    Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

    Författare :Yu-Yu Lu; [2021]
    Nyckelord :Electric vehicles; Cooling fan noise; Installation effects; Free-space measurement; Wall-mounted measurement; In-vehicle measurement; Spectral decomposition method; Tonality; Broadband noise level.;

    Sammanfattning : Owing to the ever-changing developments of battery and electric powertrain, vehicle electrification is the trend in the future. Without the presence of a combustion engine, masking effect from it reduces and noises from other components become perceivable. Among all, the cooling fan is one of the major noise sources. LÄS MER
