  1. 1. Wide-Angle Radome Design for Low-Cost Additive Manufacturing

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

    Författare :Martin Fajerberg; Mattias Nylander; [2022]
    Nyckelord :Radar; Radome; A-Sandwich; B-Sandwich; Multilayer; Polarization; Angle of Incidence; Finite Element Method; Differential Evolution Optimization; Transmission Line Theory; Honeycomb; Additive Manufacturing; Electromagnetic Theory; Technology and Engineering;

    Sammanfattning : The radome, a portmanteau of the words radar and dome, is a protective dielectric cover to protect a radar from its surrounding environment. The surrounding environment can be rain, wind, sand, dust and whatever else that might harm the radar. LÄS MER

  3. 2. An evaluation of LoRa transmission parameter selection for indoor positioning

    Kandidat-uppsats, Jönköping University/JTH, Avdelningen för datateknik och informatik

    Författare :Adina Valjakka; Anton Ahlinder; [2022]
    Nyckelord :Accuracy; Indoor positioning; LoRa; NLOS; Precision; RSSI; Transmission parameters; Trilateration;

    Sammanfattning : The purpose of this thesis is to investigate how the LoRa modulation configuration affects precision and accuracy when using LoRa for indoor positioning in non-line-of-sight conditions. The aim is to research if an optimum combination of spreading factor, bandwidth, and code rate factor can be found to result in the best possible positioning accuracy and precision, under certain predefined conditions.

  4. 3. "Vi är inte skolan" : En studie av pedagogiska ambitioner och perspektiv i den digitala undervisningsresursen Sveriges historia .

    Master-uppsats, Lunds universitet/Avdelningen för ABM, digitala kulturer samt förlags- och bokmarknadskunskap

    Författare :Ellen Nilsson Ekberg; [2021]
    Nyckelord :Museology; museums; pedagogy; education; museum pedagogy; sociocultural theory; learning resources; digitalisation; Museologi; museer; pedagogik; utbildning; museipedagogik; sociokulturell teori; undervisningsresurser; digitalisering; Cultural Sciences;

    Sammanfattning : Museums have long had an important role as institutions for learning and education. In recent years, the pedagogical role of museums has become more important. Museums can offer a different kind of learning compared to the formal education system, and museums can be important resources for schools. LÄS MER

  5. 4. Deep reinforcement learning for real-time power grid topology optimization

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Jacob Rothschild; [2021]
    Nyckelord :Deep reinforcement learning; Dueling Deep Q-Network; electricity transmission network; real-time topology optimization; sustainable energy; Mathematics and Statistics;

    Sammanfattning : In our pursuit of carbon neutrality, drastic changes to generation and consumption of electricity will cause new and complex demands on the power grid and its operators. A cheap, promising, and under-exploited mitigation is real-time power grid topology optimization (RTTO). LÄS MER

  7. 5. Själens växt : En diskursanalytisk undersökning av synen på kunskap och kunskapsförmedling inom den svenska spiritismen

    Kandidat-uppsats, Södertörns högskola/Religionsvetenskap

    Författare :Niklas Barholm; [2020]
    Nyckelord :knowledge; transmission of knowledge; spirituality; gnosis; critical discourse analysis; spiritualism; esotericism; pedagogy; kunskap; kunskapsförmedling; andlighet; gnosis; kritisk diskursanalys; spiritism; esoterism; pedagogik;

    Sammanfattning : This essay’s purpose is to explore the view on knowledge and transmission of knowledge in the Swedish, spiritualist movement during the turn of the century. The method is a critical discourse analysis of the texts of the spiritualist publication of Efteråt? between the years of 1899 and 1911. LÄS MER
