    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Dhruvi Ajit Shukla; [2022]
    Nyckelord :Wireless Power Transfer WPT ; ferrites; Litz wire; skin effect; proximity effect; electromagnetic induction; electromagnetic resonance; magnetic coupling; power efficiency; LC circuits; Trådlös kraftöverföring WPT ; ferrit; litz-tråd; hudeffekt; närhetseffekt; elektromagnetisk induktion; elektromagnetisk resonans; magnetisk koppling; effekteffektivitet; LC-kretsar;

    Sammanfattning : This thesis deals with wireless power transfer from an external source to embedded small devices (such as for conditioning monitoring, control etc.) located at different distances from the source. The proposed designs can be used in a variety of applications, including mobile phones, electric cars, unmanned aerial vehicles, robots, etc. LÄS MER

  3. 17. 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

  4. 18. Feasibility Study of Resistivity Measurement of Metal Surfaces to Address Potential Dislocations Caused by Surface Conditioning

    Master-uppsats, Uppsala universitet/FREIA

    Författare :Mircea-George Coman; [2022]
    Nyckelord :;

    Sammanfattning : High electrical fields are needed inside the accelerating cavities of particle accelerators in order to accelerate the particles to higher energies in shorter distances. But high electrical fields will lead to electrical breakdowns. LÄS MER

  5. 19. Towards Deep Learning Accelerated Sparse Bayesian Frequency Estimation

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Mika Persson; [2022]
    Nyckelord :Bayesian Statistics; Deep Learning; Frequency Estimation; Generative Adversarial Networks; Artificial Neural Networks; Statistical Modelling; Mathematics and Statistics;

    Sammanfattning : The Discrete Fourier Transform is the simplest way to obtain the spectrum of a discrete complex signal. This thesis concerns the case when the signal is known to contain a small (unknown) number of frequencies, not limited to the discrete Fourier frequencies, embedded in complex Gaussian noise.

  7. 20. Political Parties on the Move: Computational Scaling Method Applied to Swedish Parliamentary Debates

    Kandidat-uppsats, Umeå universitet/Statsvetenskapliga institutionen

    Författare :Carl-Oscar Källström Ståhlgren; [2022]
    Nyckelord :Estimation methods; political space; parliamentary speeches; political speech; text analysis; Swedish politics; algorithm; models; word frequency analysis; time series; left-right; Wordfish;

    Sammanfattning : Over the years, a variety of methods have been used in order toestimate policy positions for political parties in national parliaments. This papersets out to apply a novel computational method called Wordfish and apply it to aheavily under-researched form of political text, parliamentary speeches. LÄS MER
