  1. 1. 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

  3. 2. Model-based synthesis of singing

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

    Författare :Xiaofeng Zeng; [2023]
    Nyckelord :Singing voice synthesis; Source-filter model; Anti-resonances; SuperCollider; Sång röstsyntes; Käll-filtersmodell; Anti-resonanser; SuperCollider;

    Sammanfattning : The legacy KTH Music and Singing Synthesis Equipment (MUSSE) system, developed decades ago, is no longer compatible with contemporary computer systems. Nonetheless, the fundamental synthesis model at its core, known as the source-filter model, continues to be a valuable technology in the research field of voice synthesis. LÄS MER

  4. 3. EMG-analys av m. infraspinatus och m. deltoideus vid utåtrotation med och utan samtidig adduktionskraft

    Kandidat-uppsats, Lunds universitet/Människan i rörelse: hälsa och rehabilitering

    Författare :Jonatan Malmström; Peter Kvillegård; [2020]
    Nyckelord :Elektromyografi; skuldra; rotatorkuff; rehabilitering; utåtrotation.; Medicine and Health Sciences;

    Sammanfattning : Bakgrund Vid axelproblematik rekommenderas ofta utåtrotationsövningar för att stärka rotatorkuffen, främst m. infraspinatus. Vid dessa övningar aktiveras även m. deltoideus, som kan komprimera det subakromiella rummet. LÄS MER

  5. 4. Wireless electrocardiogram based on ultra-wideband communications

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och System

    Författare :Maria Toll; [2019]
    Nyckelord :UWB; ECG; EKG; ultra-wideband; electrocardiogram; ultra wideband; radio communication; Decawave; DW1000; IoT; internet of things; Android; IEEE 802.15.4-2011;

    Sammanfattning : The goal for this master thesis is to develop a prototype that uses ultra-wideband (UWB) communications to wirelessly transfer electrocardiogram (ECG) data from an ECG measurement unit to an Android device (smartphone or similar) which is used to process and display the ECG signals. The prototype should consist of two hardware nodes; (1) Node one having a ECG measurement unit (an AD8232 single lead heart rate monitor), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE); and (2) Node two having an Android device (an Android smartphone), an UWB communication module (a Decawave DWM1000 module) and a microcontroller (an Arduino DUE).
