1. 1. Developing a High-Voltage Mechanical Disconnector: Meeting Safety Standards

   Master-uppsats, Lunds universitet/Innovation

   Författare :Hampus Carlqvist; [2023]
   Nyckelord :Opticept; Standards; Product development; Disconnector; High Voltage; Technology and Engineering;

   Sammanfattning : This master thesis is conducted in collaboration with Opticept Technologies, a company operating in the Pulsed Electric Field (PEF) treatment industry. PEF treatment necessitates the use of high-voltage machines, and this thesis focuses on exploring a mechanical disconnector that serves as an essential safety feature for such high-voltage systems.

4. 3. A digital integer-N PLL architecture using a pulse-shrinking TDC for mmWave applications.

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

   Författare :Simon Richter; [2023]
   Nyckelord :Phase-locked-loops; All-digital Phase-locked-loops; Time-to-digital converters; 5G and beyond; Radio-frequency design; Fas-låsd-loop; Helt-digital fas-låst-loop; Tid-till-digital-omvandlare; 5G och framtiden; Radio-frekvens design;

   Sammanfattning : With the move of the broadband cellular network towards 5G taking off and the preparatory work on 6G and beyond starting, the need for low-complexity, low-power, and high-performance frequency synthesis using Phase-Locked Loop (PLL)s increases. As we get deeper into the mm-wave frequencies and push towards frequencies in the order of 50-70 GHz design challenges with existing PLL architectures, such as limited technology scaling and limited in-band noise performance become more apparent.

5. 4. Design and construction of an access concept for a tow bar mounted cargo box : Analysis and development of the user experience

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Oskar Hildestrand; Emma Karlberg; [2023]
   Nyckelord :Backbox; Tow bar cargo box; Product analysis; User-centered design; User experience; Product Design; Mechanical Design and Combination lock; Bakbox; Dragkroksbox; Produkt analys; Användarcentrerad design; Användarupplevelse; Produkt design; Mekanisk konstruktion; Kombinationslås;

   Sammanfattning : Due to the climate crisis, electrical vehicles are on the upswing. To optimize the range of electric cars, aerodynamics is an important factor to consider. Therefore, cargo boxes mounted on the tow bar, often called backboxes, have become an interesting alternative to the standard roof mounted cargo box. LÄS MER

7. 5. Evaluation of non-stationary signal processing methods for binary EEG classification

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Amanda Ledell; [2022]
   Nyckelord :Mathematics and Statistics;

   Sammanfattning : Electroencephalogram (EEG) measurements are notoriously noisy and non-stationary and there are several specialized techniques for their analysis and interpretation. In this thesis, we implement a collection of stationary and non-stationary methods including coherence, Phase Locking Value (PLV), Phase Lag Index (PLI), and their imaginary counterparts. LÄS MER
