16. Quantification of left-to-right shunt through Patent Ductus Arteriosus by colour Doppler
Abstract : The aim of this thesis was to develop a non-invasive method to quantify the size of a shunt through a patent ductus arteriosus (PDA) by ultrasound and to test its usability in clinical settings. There is no consensus regarding the optimal management strategy for a PDA in premature infants. READ MORE

17. Fault detection in district heating substations
Abstract : This thesis gives a summary of different faults that occur in district heating substations and suggests ways of detecting them. The aim of the research has been to achieve fault detection using only the heat meter and the sensors connected to it, namely two temperature sensors and one flow meter. READ MORE

18. Nasal CPAP support of newborn infants : measurements of interface leakage and performance of selected systems
Abstract : Objective: The most common treatment for newborns in respiratory distress is nasal continuous positive airway pressure (nCPAP). Comparing clinical studies have shown a better outcome and a lower risk of chronic lung disease compared to invasive mechanical ventilation (MV) when used as primary treatment. READ MORE

19. Improving heat measurement accuracy in district heating substations
Abstract : The idea of district heating is to heat up a whole district from a central source through a distribution network. The heat is extracted by heat exchangers and the water is then subsequently returned to the central source. The heat exchange between the district heating network and the building occurs in district heating substations. READ MORE

20. Computer vision for rock aggregates
Abstract : Measurement of size, shape and texture of aggregates (rockparticles) is often used in geological mapping, rockclassification, quarry and mine production. The size ofaggregates varies from micro-meters to meters, and the types ofaggregates may be classified as natural (i.e. sandstone, graveland 'natural blocks') and artificial (i. READ MORE
