Ice accumulation on aircraft surfaces is a prevalent issue, and icephobic coating strategies can be implemented to assist in the removal of or ice on an aircraft. However little is known regarding the effects of novel icephobic coatings and surfaces on ice adhesion strength, which is difficult to measure and quantify, and is typically reported...

The aim of this thesis was to objectively and quantitatively assess the accuracy and robustness of two-dimensional sequentially linear analysis (SLA) in comparison to nonlinear finite element analysis (NLFEA), for a range of experiments of reinforced concrete structures with proportional and non-proportional loading schemes. Non-proportional...

<br/>This research has shed light on the capability of the HASP model in reproducing the dilatant behaviour of OC clays in drained and undrained conditions. The model is formulated by employing a combined hardening rule and uses the void ratio as a state variable while maintaining the simplicity of the MCC model. However, a sensitivity analysis...

Shipyards these days see an increase in customers that specify combined speed and seakeeping ability design requirements. This requires the shipyard to make a prediction of the additional installed power required to maintain a certain speed when waves are encountered. The additional required installed power is directly related to the average...

A quick-scan algorithm has been developed in order to evaluate rooftop PV potential in the Netherlands. Both its panel fitting and yield prediction functions have been validated with existing systems monitored by Solar Monkey. The calculation times of different parts of the algorithm were measured and decreased while keeping the accuracy of the...

This report proposes improvements of the land surface model (LSM) used in the turbulence-resolving Dutch Atmospheric Large-Eddy Simulation model (DALES). Important changes include the infiltration of precipitation, the parametrization of the soil hydraulic functions and the formulation of the soil water extraction by vegetation roots. The...

A complex marine project consist of series of operations, with each operation subject to a predefined operational limit and duration, depending on the equipment being used. If actual weather conditions exceed the operational limit, then the operation cannot be executed and hence downtime occurs. It is up to contractors, such as Boskalis, to...

Over the last decade, it has become more common to build origin destination matrices for transport modelling using traces left by mobile phones. This thesis presents a framework for the validation of origin-destination matrices made using mobile phone data. Using the steps presented, it is possible to test the trip generation, trip distribution,...

The problem of testing the performance of an attitude control system presents new challenges and opportunities when conducted on a CubeSat scale. This is the result of drastic reduction in physical properties (size, mass, torques) as well as project resources (funds, manpower, time) when compared to traditional satellite programs. This thesis...

Introduction. Aseptic loosening is indicated as the main cause of knee implant failure. Despite all currently used techniques, it remains challenging to diagnose an aseptic loose knee implant. A promising technique to reveal aseptic loose related implant motions is inducible displacement (ID). ID measurements are used to detect implant motion...

Monitoring of coastal hydrodynamics over a relatively large spatial extent and a long temporal period is essential to assess the impact of coastline interventions on several functions. An example of a recent coastline intervention is the Sand Engine, a pilot project for optimization of (future) coastline maintenance. This innovative pilot...

Heerema Marine Contractors (HMC) operates several crane vessels, barges and tug boats for the transportation, the installation and the removal of offshore facilities. To achieve safe and successful projects, the accurate prediction of vessel motions is of great importance. Vessel motions are calculated on the basis of wave energy spectra and...

With fuel oil the main driver for operational expenses, increasingly stringent regulations on emissions of ships and a growing environmental awareness throughout the industry, the concept of Wind-Assisted Ship Propulsion (WASP) presents itself as a means to reduce fuel consumption. Though a promising concept, the performance prediction of a wind...

Over the last decades, air traffic facilitates the movement of people and goods all over the world, enabling economic growth and development. Despite the impact air traffic has on industries and systems all over the world, the aviation industry is influenced by the same factors as well. Energy prices, the economic situation, population growth...

The DNV GL Health Index translates statistical, condition and utilization data of electrical power equipment into several asset representations that show technical asset health, including expected remaining lifetimes. These remaining lifetimes are used to determine the required action for the asset manager. In this research, a method was...

To allow for efficient and robust gait pattern, humans instantaneously modulate their joint impedance. Lower-limb amputees and patients suffering from neurological diseases partly lack that ability. Therefore, prosthetic and rehabilitative devices have been designed to re- store and repair nominal locomotion. For bio-inspired control of these...

The increasing penetration of dispersed generation changes the way in which distribution grids are comprised. The impact of the introduction of grid-connected distributed energy resources is expected to receive growing attention in the near future. Power electronic equipment is now indispensable part of the electricity generation and...

Usability issues have been observed in luminaire repositioning, during surgical operations. These difficulties were confirmed to be related to the kinematics of the translational subsystem of the suspension mechanism, specifically the possibility of singularity. Due to which the required force for luminaire repositioning depends on the spatial...

During a storm dunes erode and provide sediment to the beach. The foreshore rises and the wave height decreases. Subsequently the wave-induced water level setup increases. Seawalls do not erode. The waves in front of the seawall remain high throughout the storm and the wave-induced water level setup hardly changes. Over a dune-dike connection a...
