  1. 11. Development and Analysis of Small Signal DQ-Frame Model for Low Frequency Stability of Train Converters

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Fabian Tidner; [2023]
    Keywords : Low Frequency stability; DQ-frame modeling; Single phase converter; Electric rail way systems; Lågfrekvent stabilitet; DQ-ram modellering; Enfasig likriktare; Elektriska järnvägssystem;

    Abstract : In order to meet the increasing demand for sustainable transportation, trains need to run with tighter schedules, more departures and more trains in depot. Multiple trains in depot has been linked to low frequency instability at many locations around the world. READ MORE

  3. 12. Novel Method of ASIC interface IP development using HLS

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Anestis Athanasiadis; Chandranshu Mishra; [2023]
    Keywords : High Level Synthesis; HLS; Untimed C ; Control logic; I3C; clock-accurate design; IP development; Technology and Engineering;

    Abstract : High-Level Synthesis(HLS) is a design methodology that enables designers to implement hardware from high-level coding languages, such as C, C++, or System C. It provides designers with the ability to convey their design at a higher level of abstraction, which allows more emphasis on an algorithm and functional aspects of design instead on low-level hardware details.

  4. 13. Analysis to reduce ice-related production losses for wind turbines

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Jhason Paran De La Cruz; [2023]
    Keywords : Wind power; cold climate; wind turbine icing; ice losses; ice protection systems; blade heating; de-icing; analytical dashboard; data visualization.; Vindkraft; kalla klimat; nedisning av vindkraftverk; isförluster; isskyddssystem; uppvärmning av blad; avisning; analysverktyg; datavisualisering.;

    Abstract : In the rapidly growing wind energy market, regions with cold climates are currently in the spotlight owing to their abundance of wind resources. However, the operation of wind turbines in cold climate conditions is challenged by serious icing problems. READ MORE

  5. 14. Methods for determining focal point and delay for ultrasound arrays and multichannel electronics

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Svante Rosenlind; [2023]
    Keywords : Focusing algorithms; k-wave; Spatiotemporal inverse filter; Gerchberg- Saxton algorithm; Focused ultrasound; Technology and Engineering;

    Abstract : High intensity focused ultrasound is a growing technique for tissue ablation, among other uses, and given its destructive capabilities, there is a need for control of where the energy is delivered. There exist a number of methods for focusing such ultrasound arrays, but these often assume prior knowledge of the impulse response, or require extensive full-system simulations. READ MORE

  6. 15. Towards a setup for narrowband terahertz generation through difference-frequency mixing of chirped ultrashort pulses

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Isa Clementsson; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficiencies as high as a few percent.
