A Distributed Actuator Concept Analysis

Timmerman, R.R. (author)

Most conventional actuation methods have a very limited degree of freedom, simply moving from point A to B. In contrast to the concept of distributed actuation which divides up actuation in such a way that a networked structure of smaller actuators operating in tandem is able to take on various forms. Previous research by other groups has...

Photocatalytic Enhancement of SiO2 coated Degussa P25 TiO2 Nanoparticles by Scalable Atmospheric Pressure Atomic Layer Deposition

Song, Y. (author)

This work investigates the enhancement of photocatalytic activity of titanium dioxide (TiO2) commercial particles by ultrathin silicon dioxide (SiO2) films deposited via atmospheric pressure atomic layer deposition (ALD) carried out in fluidized bed reactor (FBR). The ALD process enabled precise control for the growth of ultrathin film at sub...

Photocatalytic Properties of SiO2 coated Degussa P25 TiO2 Nanoparticles by Scalable Atmospheric Pressure Atomic Layer Deposition

Song, Y. (author)

A precise control for the growth of thin film powered by atmospheric pressure atomic layer deposition (ALD) carried out in fluidized bed reactor makes the ultrathin conformal coating of SiO2 on Degussa P25 TiO2 nanoparticles possible. At an operating temperature which can be lowered to room temperature (~27°C), the growth per cycle (GPC) smaller...

Redesigning Allseas’ Lorelay: An investigation into the possible conversion options to increase the ship’s utilisation, resulting in a preliminary design

Kooij, C. (author)

In the last year Allseas’ Lorelay has had very little work. Due to a bad market, very little available projects and heavy competition the ship has laid idle for the better part of the year. Allseas is wondering how the utilisation of the ship can be increased without losing her pipe laying capabilities. This question is reworked into the...

FCEV as power plant: a techno-economic scenario analysis in two climates for smart cities

Smink, G. (author)

In the Paris Agreement a total of 195 countries agreed on a legally binding climate deal to bridge towards climate-neutrality before the end of the century. This requires affordable zero emission, heat and transport systems. This research answers the question whether solar and wind generated electricity, with the integration of fuel cell...

More Smileys on the road

van der Vorst, H.M. (author)

Congestion is one of the big annoyances people experience in their everyday life. Furthermore, congestion has negative effects on both the environment and the economy. In short, it forms a very big problem to society. This thesis focuses on a specific type of congestion, namely a ‘wide moving jam’. This is typically a short jam that propagates...

Evaluation of a smart electrosurgical knife: assessing the feasibility of tumour detection with Diffuse Reflectance Spectroscopy in breast conserving surgery

Adank, M.W. (author)

Every year, 1.7 million woman are diagnosed with breast cancer worldwide. Breast Conserving Surgery (BCS) – where not the whole breast but only the tumour is dissected – is the most common and preferable treatment for these woman. However, 20 to 55% of the patients’ needs a second surgery because of positive margins. A dissected tumour has a...

Damping Identification of an Offshore Wind Turbine: A Predictor-Based Subspace Identification Approach

van der Hoek, D.C. (author)

Increasing the capacity of offshore wind energy is a necessary step in the transition from fossil fuels to renewable energy sources. In order to accelerate this process, the costs of wind energy should be reduced to make it more competitive with traditional energy sources. Cost reduction could be achieved by increasing the lifetime of an...

Ice Rink Protection Systems: Improve and Apply a Numerical Model to Gain Insight in the Safety of Ice Rink Protection Systems

Bruinsma, Y. (author)

Many falls occur in speed skating, most of which end up in protective padding that is placed along the ice rink. In this research project a testing method was established that can be used to test the influence of different padding parameters on the performance of the padding in relation to the skaters’ injury risks. An existing numerical model...

Tensegrity Locomotion on Rough Terrain: A quasi-static approach

Tournois, G.A. (author)

Tensegrity robots are researched for robotic locomotion, as they have remarkable properties which makes them well suited for physical interaction with unknown and unstructured environments. So far, locomotion on rough terrain has not been demonstrate, but only on flat and moderately hilly terrain. Moreover, research merely focuses on rolling and...

Support Structure Optimization: On the use of load estimations for time efficient optimization of monopile support structures of offshore wind turbines

Maljaars, J.L. (author)

Over the years, the installed capacity of offshore wind turbines is increasing rapidly. However, the Levelized Costs Of Energy (LCOE) is still higher than the LCOE of traditional energy production methods like nuclear power or energy from coals or gas. This research focuses on a further decrease of the LCOE, by minimizing the mass of a monopile...

Vessel Motion Sensing: with Absolute Reference Measurement

Ten Pas, S. (author)

Offshore structures, like windmills and oil or gas platforms, require regular maintenance and operators to continue working. Rough seas and weather conditions caused a problem to get people on and off these offshore structures until in 2009 Ampelmann came with a solution to safely transfer people offshore. This people transfer is done by means...

Self Healing Alumina Composite with MAX-phase Particles

Bosch, M. (author)

The use of Ti2AlC MAX-phase as healing particles to heal surface cracks in alumina is studied. Pure Ti2AlC and the alumina composite (Al2O3-20 vol. % Ti2AlC) were synthesised by Spark Plasma Sintering. The kinetics of the oxidation of MAX-phase into rutile and alumina, were studied via Thermo- Gravimetric Differential Thermal Analysis. The...
