Deposition of luminescent thin films for solar energy applications

Photovoltaic devices are a widely available, long lasting means of generating sustainable energy. Unfortunately, the integration of such devices into society is to date still limited. This is in part due to the much less than optimal efficiency of conversion of sunlight to electricity, but also by the physical limitations of integrating...

Forming of Laminates

Fibre-Metal-Laminates have excellent properties for aerospace applications, with GLARE as an example. The metal layers inside the laminate provide permanent plastic deformations for the whole laminate; in principle Fibre-Metal-Laminates can be formed with common sheet metal forming processes. The difference between monolithic sheet metal and...

Nitrogen compounds in pressurised fluidised bed gasification of biomass and fossil fuels

Fossil fuels still dominate the energy supply in modern societies. The resources, however, are depleting. Therefore, other energy sources are to be exploited further within this century. Biomass is one of the practically CO2 neutral, renewable contributors to the future energy production. Nowadays many modern, high efficiency (combined) power...

Scheidslijnen in het denken over natuurbeheer in Nederland: Een genealogie van vier ecologische theorien

In 1972, a number of Dutch landscape ecologists united in the Netherlands Society for Landscape Ecology (in Dutch: Werkgemeenschap Landschapsecologisch Onderzoek, WLO). They formed a theory discussion group, aimed at finding a scientific foundation for nature conservation. Scientific here meaning: to be able to predict the future, on the basis...

Range imaging and visual servoing for industrial applications

High-tech systems play a key role in Printed Circuit Board (PCB) manufacturing. Two of these systems are presented in this thesis. The first system is range imaging, which is a measuring technique for determining three-dimensional shape. The second system is visual servoing, which is a method of adaptively controlling a mechanical system by...

Seakeeping Behaviour of High Speed Ships: An Experimental and Numerical Study

In recent years, great progress has been made in both the optimisation of the seakeeping behaviour of fast ships and the development of efficient numerical methods for computation of the seakeeping behaviour of ships in general. The study presented in the thesis aims to integrate both developments. First, the key aspects of the seakeeping...

Modelling and optimization of thermal processes in the dairy industry

Continuous Descent Operations using Energy Principles

During today’s aircraft descents, Air Traf?c Control (ATC) commands aircraft to descend to specific altitudes and directions to maintain separation and spacing from other aircraft. When the aircraft is instructed to maintain an intermediate descent altitude, it requires engine thrust to maintain speed, leading to increased fuel burn and noise...
