    University essay from Uppsala universitet/Avdelningen för visuell information och interaktion

    Author : David Holst; [2019]
    Keywords : ;

    Abstract : The current DICOM communication standard for radiotherapy is outdated and has serious design issues. A new version of the standard, known as DICOM 2nd generation for Radiotherapy, has been introduced and this thesis examines new concepts relating to radiation delivery. READ MORE

  3. 3. Wireless electrocardiogram based on ultra-wideband communications

    University essay from Uppsala universitet/Signaler och System

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

    Abstract : 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).

  4. 4. Design and construction of a bidirectional DC/DC converter

    University essay from Uppsala universitet/Elektricitetslära

    Author : Alexander Wallberg; [2019]
    Keywords : Converter; DCDC; Energy storage; Single-phase; Omvandlare; DCDC; Energilager; Single-phase;

    Abstract : A four quadrant general single-phase bi-directional DC/DC converter was designed and constructed for high effect systems. The target application for the DC/DC converter was to be used to transfer energy between different energy storages, a miniature DC power grid and the high voltage AC power city grid. READ MORE

  5. 5. Exhaust Temperature Modeling and Optimal Control of Catalytic Converter Heating

    University essay from Linköpings universitet/Fordonssystem

    Author : Victor Petersson; [2019]
    Keywords : cold-start; catalyst heating; ignition retardation; GDI;

    Abstract : After reaching its light-off temperature, the catalytic aftertreatment system plays a major part in maintaining emissions at low levels for vehicles equipped with combustion engines. In this thesis, modelling of the exhaust gas temperature is investigated along with optimal control strategy for variable ignition and exhaust valve opening angles for optimal catalytic converter heating.
