Concrete is a brittle composite material that easily fractures under tension. Due to the fact that the early-age deformation of the concrete member is restrained by adjoining structures, cracking can occur throughout the concrete prior to application of any load. The cracks would provide preferential access for aggressive agents penetrating in...

Massive Open Online Courses (MOOCs), as one of the popular options for people to receive education and learn, are endowed with the mission to educate the world. Typically, there are two types of MOOC platforms: topic-agnostic and topic-specific. Topic-agnostic platforms such as edX and Coursera provide courses covering a wide range of topics,...

This thesis investigates the efficiency of wind energy conversion from three aerodynamic perspectives. The first, purely theoretical, assumes steady inviscid flow conditions to identify multi-rotor setups that can extract more power per unit area than isolated rotors. The second, more practical perspective, assesses the extent to which site...

Road transport heavily relies on fossil fuels and contributes to a series of problems including pollution, greenhouse gas emissions and fuel dependence. Replacing fossil-fuel powered vehicles with electric vehicles (EV) on a large scale is regarded as a potential or even necessary solution to alleviate these problems. Therefore, many national...

The crowd increasingly plays a key role in facilitating innovations in a variety of sectors, spurred on by IT-developments and the concomitant increase in connectivity. Initiatives in this direction, captured under the umbrella-term ‘crowd-based innovations’ (CBI), offer novel opportunities in all domains of society by increasing the access,...

With the rising demands from customers and users and the development of ever advanced technologies, many space missions nowadays require more than one satellite to fulfill their mission objectives. Although replacing single satellite systems (SSSs) by multiple satellite systems (MSSs) offers advantages, such as enhanced spatial and temporal...

It is difficult to accurately predict the strength of masonry and concrete structures. The most widely used method for simulating their behaviour is finite element analysis with the Newton-Raphson method and arch length control. However, the Newton-Raphson method can diverge and not produce a result, for example in bifurcations or during snap...

During the primary oil recovery, wells are drilled into the reservoir, and due to natural driving forces, the oil flows to the surface through these production wells. Unfortunately, the production of oil in this first stage is typically between only five and ten percent of the oil in place in the reservoir. In the secondary oil recovery some...

This study aims at improving the hydrological process understanding of the semi-arid and transboundary Incomati river basin to enable better water management. Comprehensive statistical and trend analysis of rainfall and streamflow were conducted, and the Indicators of Hydrological Alteration tool was deployed to describe the streamflow regime...

Purpose: This paper highlights the importance of user satisfaction in office renovation. A user-focussed renovation approach can enhance user satisfaction in offices and their functional quality while meeting energy performance goals. The purpose of this paper is to investigate users’ needs and the physical and psychological factors affecting...

A marine project consists of series of operations, with each operation subject to a predefined operational limit and duration. If actual weather conditions exceed the operational limit, the operation cannot be executed and hence downtime occurs. An accurate assessment of uncertainties and the expected downtime during a marine project is...

We hebben in Nederland ongeveer 20.000 km waterkeringen en het is kostbaar en tijdrovend om deze regelmatig fysiek te inspecteren. Met radarsatellieten wordt deformatie op meer plekken, vaker, en nauwkeuriger gemeten. Hierdoor kan het gedrag van keringen continu worden gemonitord en kan afwijkend gedrag vroegtijdig worden gedetecteerd. Deze...

The modelling of social-ecological systems can provide useful insights into the interaction of social and environmental processes. However, quantitative social-ecological models should acknowledge the complexity and uncertainty of both underlying subsystems. For example, the agent-based models which are increasingly popular for groundwater...

Gebiedsontwikkelingsopgaven in de hedendaagse verstedelijking zijn per definitie meerduidig. Het gaat in 2019 niet meer om een eenduidig doel zoals wijkvernieuwing of de vitalisering van een bedrijventerrein. De opgaven in de grote steden gaan over verdichting, vermenging, vergrijzing én segregatie, maar ook over betaalbaarheid, gezondheid,...

Health literacy, i.e. the ability to read and understand medical text, is a relevant component of public health. Unfortunately, many medical texts are hard to grasp by the general population as they are targeted at highly-skilled professionals and use complex language and domain-specific terms. Here, automatic text simplification making text...

Optimal selection of safety measures (SMs) is a challenging task for safety managers due to its importance, complexity, and incapability of traditional approaches in considering all the aspects of SMs optimal selection. Sophisticated mathematical models can be used to overcome the limitations of traditional approaches. However, setting the...

A parallelized flight simulator for the dynamic analysis of airborne wind energy (AWE) systems for ground- and fly-generation configurations is presented. The mechanical system comprises a kite or fixed-wing drone equipped with rotors and linked to the ground by a flexible tether. The time-dependent control vector of the simulator mimics real...

Quantum computing promises an exponential speed-up of computation compared to what is nowadays achievable with classical computers. In this way, it enables the evaluation of more complex models and the breaching of current security algorithms. For the operation of a quantum system, many questions remain to be answered. Currently, there are...

We present a multidisciplinary design optimization method for the profile and structural reinforcement layout of a ram‐air kite rib. The aim is to minimize the structural elastic energy and to maximize the traction power of a ram‐air kite used for airborne wind energy generation. Because of the large deformations occurring during flight, a fluid...
