  1. 16. Test/programmeringsstation av PCB

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Jennifer Underdal; Gustaf Löfdahl; [2022]
    Nyckelord :;

    Sammanfattning : Aimpoint is a Swedish company that develops and produces sights towardscivil and military use. 1975, they were the first company ever to release a reddot sight. And as of last year, 2021, they released Acro C-2 and Acro P-2, asecond generation Acro sights and successors to Acro C-1 and Acro P-1. LÄS MER

  2. 17. Design of LED setup for measuring tandem solar cell subcell J-V behaviour

    Kandidat-uppsats,

    Författare :Kristina Bergström; Mohammed Nour Kamalmaz; Erik Lindvall; [2022]
    Nyckelord :Tandem solar cell; LED; background light; bias; arduino; processing; subcell;

    Sammanfattning : The need to accurately measure multi-junction (MJ) tandem solar cells' subcell current-voltage characteristics is increasing due to the vital information they provide about the efficiency, stability, and longevity of the cells. These measurements are rather difficult compared to their counterpart single-layer solar cell measurements. LÄS MER

  3. 18. An Inexpensive Alpha Spectrometer Based on a p-i-n Photodiode : Making Advanced Particle Detectors From Common Commercial Components

    Kandidat-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Elias Arnqvist; [2022]
    Nyckelord :Alpha spectroscopy; alpha particle; particle detector; radiation detector; p-i-n diode; PIN diode; photodiode;

    Sammanfattning : The purpose of this project was to design, construct, and evaluate an alpha spectrometer based on an inexpensive p-i-n photodiode as a radiation detector. The BPX-61 p-i-n photodiode was selected and calculated to have a 93 µm wide sensitive volume at 25 V reverse bias. LÄS MER

  4. 19. Investigating the use of Semiconductor Nanowires for Neural Networks

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Alfredo Serafini; [2022]
    Nyckelord :FDTD method and simulation; optical broadcasting neural network; optical communication of nanowires; sub-wavelength absorption.; Physics and Astronomy;

    Sammanfattning : In this work, we intend to employ nanowires for the realisation of an artificial neuron which can be used to design a neural network that will guide the new generation of non-von Neumann architectures such as Neuromorphic Computing. Possible applications are strongly related to Neuromorphic architectures and artificial intelligence, such as high-performance computers, robotics hardware and autonomous drones. LÄS MER

  5. 20. Analysis and Performance Evaluation of a Three-phase Three-level Sparse Neutral Point Clamped Converter for Industrial Variable Speed Drives

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

    Författare :Pengpeng Sun; [2022]
    Nyckelord :Sparse Neutral Point Clamped Converter; Industrial Variable Speed Drives; Silicon IGBT; Calorimetric Measurement; Reverse Recovery Energy; Sparse Neutral Point Clamped Converter; Industriella Varvtalsstyrda Motordrifter; Silicon IGBT; Kalorimetrisk Mätning; Energi för Återhämtningsprocess;

    Sammanfattning : This thesis project focuses on the simulation, design, hardware realization, and performance evaluation of a Three-phase Three-level (3-L) Sparse Neutral Point Clamped Converter (SNPCC) for Industrial Variable Speed Drives (VSDs). The basic operating principle of the SNPCC is briefly described based on switching functions. LÄS MER
