  1. 1. Independent validation of a system for real-time localization of the prostate during motion tracking radiotherapy

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Klara Stefansson; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Intrafractional prostate motion during external beam radiotherapy of prostate tumors has been reported as a limiting factor in accurate treatment delivery. Technology for real-time image-guided radiotherapy has been introduced for tracking and for compensating prostate motion during treatment and could allow for reduced target margins. LÄS MER

  3. 2. Filtering Pressure Oscillations in a Common Rail Pressure Signal with IIR Notch Filters for Injected Fuel Amount Estimation

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

    Författare :Marcus Akkila; Denis Ramsden; [2023]
    Nyckelord :DSP; Water hammer effect; IIR; Common-rail; Injected fuel amount estimation; Notch filter; Water hammer effect; IIR; Digital signalbehandling; Injektionsmängd; Common-rail; bandstoppfilter;

    Sammanfattning : This project concerns an inline six-cylinder (I6) diesel truck engine equipped with common-rail injection system. It has been done at the Swedish truck manufacturer Scania CV AB. The main focus is digital signal processing of the rail pressure sensor signal from the injection system. LÄS MER

  4. 3. Evaluating the use of clock frequency ratio estimators in the playout from video distribution networks

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

    Författare :Emil Myresten; [2023]
    Nyckelord :Clock Frequency Ratio Estimator; Real-time Transport Protocol; RTP; Video Distribution Network; Playout Scheduling; Clock Skew; Clock Synchronization; Uppskattning av klockfrekvensratio; Real-time Transport Protocol; RTP; Distributionsnätverk för video; Utspelningsschemaläggare; Klockskevning; Klocksynkronisering;

    Sammanfattning : As traditional TV-broadcasters utilize the Internet to transport video streams, they often employ third party distribution networks to ensure that the Quality of Service of the packet stream remain high. In the last step of such a distribution network, a playout scheduler will schedule the packets so that their intervals are as close as possible to the intervals with which they were initially sent by the source.

  5. 4. Detection and Tracking of Elephants using Seismic Direction of Arrival Estimates

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Albin Westlund; Daniel Goderik; [2023]
    Nyckelord :Wildlife Conservation; DOA Estimation; Geophone Array; Target Tracking; Elephant Detection;

    Sammanfattning : As human settlement expands into the natural habitats of wild animals, the conflict between humans and wildlife increases. The human-elephant conflict is one that causes a tremendous amount of damage, often to poor villages close to the savannah. LÄS MER

  7. 5. Estimation of respiratory frequency from Heart Rate Variability

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Daniel Ågärd; [2023]
    Nyckelord :time-frequency analysis; multitaper spectrogram; Optimization; signal processing; heart rate variability; Mathematics and Statistics;

    Sammanfattning : In this master's thesis the ability to estimate the respiratory frequency from heart rate variability measurement is analyzed. The goal was to implement a solution that is easily transferable to real time. LÄS MER
