How to measure the intra-ocular pressure

The intra-ocular pressure (IOP) is one of the most important parameters which are relevant for a proper eye care. It is essentially a pressure of a fluid that fills the interior chambers of the eye and it is measured in mmHg. Ophthalmologists agree that the range of IOP for normal and healthy eyes lies between 10 and 20 mmHg with the mean around 15-16mmHg. The value of IOP that is located above the aforementioned normal range may be an indicator of a development of a disease called the glaucoma which in turn may lead to a vision damage and even blindness. Therefore, the determination of a true value of IOP is crucial for diagnosing this very serious sight disorder. More detailed description

Thrusters with additional stators

Today’s tunnel thrusters in ships have only one fix pitch or controllable pitch propeller. With this configuration thruster outflow have tangential component which creates thrust and radial component creating mainly losses. Objective is to design stator blades which would enhance the efficiency of the propeller, by using this radial component, in order to create additional thrust. More detailed description

Solar farm modelling

The problem to be solved is the modeling of a photovoltaic farm as arises in real life. Placing it in different locations such as level ground, a horizontal or sloping roof shall be considered. More detailed description

Detection and compensation of Vortex Induced Vibrations

As a part of deliveries of work over riser systems FMC Technologies provide riser monitoring systems. The systems perform measurements of load and deformation at specified positions on the work-­‐over systems and on permanent equipment such as subsea trees and wellheads. Based on load input from sensors the FMC monitoring system can continuously calculate load distributions in lower stack. More detailed description

Non-aerobic water purification reactor

Anaerobic wastewater purification processes have been increasingly used in the last few decades. These processes are important because they have positive effects: depollution of higher organic loading, which includes low sludge production and high pathogen removal, methane gas production and low energy consumption. The increased interest in these processes has stimulated mathematical modelling, because it is usually much faster and less expensive to model a system and to simulate its operation than to perform laboratory experiments. Here we need to analyse how mathematical descriptions of bacterial population dynamics can model real data. Parameters which are simultaneously determined using information from the experiments have more reliable estimates. We ask the group to construct a model to predict the outlet Chemical Oxygen Demand (COD) with respect to varying operational parameters such as organic loading, COD/ sulphate ratio and reaction time and compare it with actual results.

Performance of a pn junction in a solar cell

The project will concentrate on modeling and performance optimization of a semiconductor device, focusing on a pn junction, which is a key component in solar cells. More detailed description

Mathematical modeling of displacements and thermal stresses in anisotropic materials in cooling

In this theme, the mathematical equations for transient and coupled heat transfer, displacements and thermal stresses are formulated for isotropic/anisotropic 3D and axi-symmetric solid material (sapphire) during the cooling. It is assumed, that the solid is initially at temperature close to its melting point temperature, and the cooling takes place until the solid is at room temperature. The cooling is organized with decreasing heater power (heat source) in the system, or with decreasing temperature (transient Dirichlet) boundary condition on the external wall of the system.
