The maintenance and improvement of river embankments plays a crucial role in granting the safety and ensuring the quality of life of the inhabitants of the Netherlands. While the threat posed by storm surges has been greatly reduced since the implementation of the Deltaworks, riverine areas in the west of the country are characterised by the...

The introduction of the new 'Waterwet' led to the retesting of a lot of primary flood defences within the Netherlands, sequentially certifying a lot of levees as unsafe regarding inner slope stability. To test or design a levee an adequate amount of soil investigation is required to indicate the presence of different soil types, stratification...

One of the main challenges in dike design in the Netherlands is to guarantee a sufficient safety level against the development of macro-instabilities in a dike. A case study was performed on a dike section at Herrewijnen-Opijnen, which is part of the Heesseltse Uiterwaarden in the Dutch province of Gelderland. The dike located at this site no...

Designers are motivated to create more a efficient aircraft design following the growth of the market and environmental restrictions. As a result new interest in propeller-powered aircraft as such engines show higher theoretical propulsive efficiency as compared to turbofan engines.

The employment of turboprop engines on commercial...

High-rise buildings are a potential solution to the environmental impact caused by the built environment and the increasing demand for space in urban areas. As recent developments focus on reducing the impact by operational energy (OE) (heating, cooling, hot water and ventilation during use phase), impact by the embodied energy (EE) (production,...

This master thesis focuses in the study of the application of active flow control in the transitional regime (Re ≈ 3E3) at the rear part of the roof of a 2D Ahmed body geometry. To do so, the natural bifurcations of the problem (which separate the ordered laminar behavior from the first pre-turbulent chaotic behavior) are studied, and different...

Hybrid laminar flow control (HLFC) reduces skin friction drag, by combining boundary layer suction with pressure gradient tailoring to delay boundary layer transition. This research addresses two key developments required to perform the aerodynamic design of suction-type HLFC components. First, an existing numerical transition prediction tool...

Tunnel construction projects in the western part of the Netherlands are typically built in soft, heterogeneous ground conditions with low stiffness and high groundwater tables. The tunnelling technique used is the ‘slurry shield’ method, which uses a tunnel-boring machine (TBM). The TBM consists of a steel cylinder with a cutting wheel at the...

A key requirement for enabling Mars manned mission is the capability to land a payload within 100 m from its nominal target. State of the art technology, however, is still far from reaching this objective. A possible solution for improving the landing accuracy on Mars is the development of a guidance system that exploits thrusters installed on...

PLAXIS study of a primary flood defence in the Netherlands. The influence of water level, precipitation, and wave overtopping on the position of the phreatic surface is being investigated. The hydraulic loads are applied to a clay dike with a cracked top layer and a sand dike with a cracked clay cover. The findings are related to the current...

A Variable Stability (VS) aircraft allows variations of response characteristics and Handling Quality (HQ) of an aircraft. By allowing for changing aircraft characteristics, the VS system has a diverse range of applications which include aircraft development, research of HQs, system tests and pilot training. This research investigates whether...

The Ayeyarwady River is the most important river in Myanmar, connecting the cities Mandalay and Yangon, making inland water transport economically attractive. The Ayeyarwady River has a dynamic character, caused by the significant discharge difference between the dry and rainy season, and the related suspended sediment transport. Point bar...

This Thesis studies the safety assessment method for macro-stability of dikes with high foreshores. Currently, this method is a semi-probabilistic method, which does not take the presence of a foreshore into account. The research concludes that the presence of a foreshore has a significant influence on the failure probability with respect to...

Currently, lower-body exoskeletons for
paraplegics are investigated as an alternative to wheelchairs
and as an exercise method with medical benefits. Literature
provides little examples for users to influence the
length or frequency of steps taken by the exoskeleton,
complicating stability and practical usability. This study...

Density Functional Theory (DFT) calculations were performed to explore the electrochemical properties of two organic molecules that show promise to serve as affordable and safe anode materials in aqueous sodium-ion batteries. Upon sodium insertion, N,N’ –bis(methyl)- 1,4,5,8-naphthalene diimide (NDMe) appears to share sodium atoms with three...

Wire and arc additive manufacturing (WAAM), a relatively new metal 3D-printing technique, allow fabrication of shapes that were not possible to produce a few years ago. Using 6-axis industrial robots with a gas metal arc welding (GMAW)-head, Dutch start-up MX3D prints metal to every direction in mid-air. By welding
small parts of material at...

The static stability of stones on mild slopes under wave attack is investigated in this research. The first part of the research is focused on reproducing the physical scale model tests regarding profile change of Kramer (2016) numerically with the model XBeach-G. The erosion profiles modelled with the bed-load transport formulas of Nielsen ...

The ever-increasing road transport demand in the developing and the developed world has resulted in road-traffic networks nearing maximum capacity. Traditional approaches to this problem, such as increasing road capacity, do not offer long-term solutions. Combined with rising environmental concerns, the demand for smarter solutions has never...

Stability and security of the grid are two vital aspects of energy supply. To keep the grid stable, it is necessary that the electricity plant can control and protect the mechanism. In the past, traditional plants could meet these requirements. Nowadays, the share of sustainable power sources in total electricity generation has become so...
