Modelling CO2 Foam Displacements for Enhanced Oil Recovery

Increasing demand for oil in the near future implies the need for Enhanced Oil Recovery (EOR) methods to produce the remaining oil after primary and secondary production. Miscible gas injection has an excellent microscopic sweep efficiency; however due to density difference, high gas mobility and reservoir heterogeneity, the macroscopic sweep...

Multiuser Detection for Sensing Asynchronous LED Illumination Contributions

In recent years, light-emitting diodes (LEDs) have played an increasingly more important role for light illumination. Beyond the basic function of pure illumination via intensity control of xed color light, LED technology additionally allows control over the light color and illumination pattern. In order to realize these functions of intelligent...

A Double-mode Linear Imaging System for IC-compatible Microspectrometers in Visible Light

In this thesis, a double-mode linear imaging system is designed for the application of microspectrometers. The imaging system is optimized so as to work with a Planar Double Grating System and a Linear Variable Optical Filter, the combinations of which would be suitable candidates of high-resolution low-cost microspectrometers. This linear...

Hospital Investomania: Design and validation of a simulation game to facilitate change in hospital capital cost decision making

A simulation game has been designed to allow stakeholders within the Dutch hospital to understand how their decision making will impact the financial performance of the hospital. This has been designed in the context of the dutch healthcare market reformation.

Swell propagation in a natural coastal channel in the SWAN model

Compare the 1D spectrum computed in SWAN (Svasek, 2007) with it measured by buoy OS4 in the Oosterschelde Estuary, serious underestimation of wave energy can be found on low-frequency band. Investigation has been performed to find the possible reasons for the missing energy on low frequency part. In this study, diffraction is hypothesized as the...

Wake Vortex Encounter Analysis with Different Wake Vortex Models Using Vortex-Lattice Method: A numerical study

The steady increase in air traffic creates a need for an increase in airport capacity. To achieve this we need to safely reduce existing separation standards. An important limiting factor in establishing required separation standards is the risk imposed by wake vortices. To determine the risk, the induced rolling moment plays a dominant role in...

Dealing with Uncertainties by Bouncecasting Application in ISA Implementation

Refinery hydrogen management

Nowadays, refineries face a double challenge: increasing hydrogen consumption for deeper hydrotreating, together with stricter environmental legislation on the sulfur content of fuels, which further increases refinery hydrogen demand. Therefore,hydrogen system is bottlenecked and hence hydrogen management has become a priority issue in current...

Throughput analysis of some mobile packet radio protocols in Rician fading Channels

The throughput of packet radio channels is investigated theoretically using the interference model in Rician fading environment. Three types of packet protocols are considered, namely: i) slotted ALOHA, ii) unslotted nonpersistent ISMA, and iii) slotted nonpersistent ISMA. Numerical results are presented, indicating the effect of propagation...

Automatic Call Registration Unit

In het kader van het project Rurale Telefonie is onderzoek gedaan naar speciale functies die kunnen worden toegevoegd aan een "ruraal" telefoontoestel. Hierbij is gekozen voor de implementatie van de mogelijkheid van registratie van inkomende oproepen bij afwezigheid. Bij thuiskomst kan de abonnee zien hoeveel gesprekken zijn binnengekomen en...
