Validation of a New Transcutaneous tcPO₂/tcPCO₂Sensor with an Optical Oxygen Measurement in Preterm Neonates

Introduction: Traditional transcutaneous oxygen (tcPO2) measurements are affected by measurement drift, limiting accuracy and usability. The new potentially drift-free oxygen fluorescence quenching technique has been combined in a single sensor with conventional transcutaneous carbon dioxide (tcPCO2) monitoring. This study aimed to validate...

Comparison of frequency-domain and continuous-wave near-infrared spectroscopy devices during the immediate transition

Background: Non-invasive monitoring of cerebral tissue oxygen saturation (rcSO₂) during transition is of growing interest. Different near-infrared spectroscopy (NIRS) techniques have been developed to measure rcSO₂. We compared rcSO₂ values during the immediate transition in preterm neonates measured with...

Model-based Optimization of Oil Recovery: Robust Operational Strategies

The process of depleting an oil reservoir can be poured into an optimal control problem with the objective to maximize economic performance over the life of the ?eld. Despite its large potential, life-cycle optimization has not yet found its way into operational environments. The objective of this thesis is to improve operational applicability...

The egg model - A geological ensemble for reservoir simulation

The ‘Egg Model’ is a synthetic reservoir model consisting of an ensemble of 101 relatively small three-dimensional realizations of a channelized oil reservoir produced under water flooding conditions with eight water injectors and four oil producers. It has been used in numerous publications to demonstrate a variety of aspects related to...

Hierarchical Economic Optimization of Oil Production from Petroleum Reservoirs

In oil production waterflooding is a popular recovery technology, which involves the injection of water into an oil reservoir. Studies on model-based dynamic optimization of waterflooding strategies have demonstrated that there is a signifcant potential to increase life-cycle performance, measured in Net Present Value. However, in these studies...

Model-Based Control and Optimization of Large Scale Physical Systems - Challenges in Reservoir Engineering

Due to urgent needs to increase efficiency in oil recovery from subsurface reservoirs new technology is developed that allows more detailed sensing and actuation of multiphase flow properties in oil reservoirs. One of the examples is the controlled injection of water through injection wells with the purpose to displace the oil in an appropriate...

Baggerspecie in Zee: Hoe regelen we dat verantwoord? Een nieuw effectgericht beoordelingsysteem

Baggerspecie is geen primaire bron van verontreiniging. Het gaat om materiaal dat vervuild is geraakt door emissies vanuit de scheepvaart, industriële lozingen, atmosferische depositie enzovoorts. Maatregelen die deze primaire bronnen aanpakken zijn uiteraard het meest effectieve middel om de verontreiniging tegen te gaan. Gegeven de...
