|| (2916-01-01) The moderation effect of brand personality on the effectiveness of different types of humorous advertisements|
Using humor to communicate various brand personalities in advertising can often be observed in practice, but scholars seldom investigated its effects. Humorous ads implied positive effects on brand equity and purchasing propensity. Recent findings in advertising research contradict the assumption of brand personality specific humor effectiveness. This study predicts and finds the moderate effect of brand personality on the relationships among different humorous ads, building brand equity, and bo....................

Dijk, I. van
Crowdfunding is an alternative form of financing that is rapidly gaining popularity. Unlike the crowdfunding landscape in the US, the Chinese crowdfunding landscape is not yet well understood. This thesis aims to overcome this gap in the literature by investigating the factors of success of Chinese reward-based crowdfunding projects and comparing results to the US, based on Hofstede’s cultural six-dimensional model and signaling theory. Based on empirical evidence, this study shows that crowdf....................

Bouwman, Dennis (author)
Using an idealized width-averaged model, the influence of spring-neap cycles on the transport and trapping of suspended fine sediment in tide-dominated estuaries is investigated. To this end we introduce a multiple time scale expansion. This provides a mathematically sound argument for treating the fast ebb-flood cycle and the slow spring-neap variations as independent time scales. With this expansion, semi-analytical approximations of the water motion and suspended sediment concentrations can b....................
|| (2019-07-05) Efficient Neural Network Architecture Search|
YANG, MINGHAO (author)
One-Shot Neural Architecture Search (NAS) is a promising method to significantly reduce search time without any separate training. It can be treated as a Network Compression problem on the architecture parameters from an overparameterized network. However, there are two issues associated with most one-shot NAS methods. First, dependencies between a node and its predecessors and successors are often disregarded which result in improper treatment over zero operations. Second, architecture paramete....................
|| (2019-07-01) Property Bidding War Strategies for the Dutch Housing Market Using an Agent-Based Model|
Ziengs, Bart (author)
The use of certain buyer strategies in the process of property bidding is being discovered in this paper. An Agent-based model is introduced where financial statistics are based on the Dutch housing market. Three types of agents are used in this model that uses cycles of two weeks. Thee hypotheses about the market are initially formulated. In the end, it proved that only the hypothesis "Initial overbidding on the list price results in a higher success rate" could be confirmed.
|| (2019-06-30) An origami inspired spherical transformable metamaterial based on symmetry groups|
Nuijts, Ivar (author)
This thesis presents a transformable metamaterial, inspired by origami. Generally, metamaterials are build up following the periodicity of Bravais lattices. This study aims to design a structure not following the Bravais lattices, but rather a different type of symmetry which tiles a sphere, in order to expand on current design studies. In this report the different types of spherical symmetries are discussed and the icosahedral symmetry group is used to design a theorical model. Then a prototype....................
|| (2019-06-28) Designing Organisational Revolution: Exploring the role of design in the quest for progressive organisations|
Davidse, Max (author)
Organisations find it more and more difficult to deal with our changing times, as our world has drastically changed over the last decades. This has led us to believe that organisational theory and practice from the last decades just does not hold up anymore. They have created organisations that made sense then, but do not necessarily now. Organisations themselves need to change in order to keep up with this sped up world. To achieve better success, many organisations are (constantly) entrenched ....................

Bootsma, Nynke (author)
The global environmental issues are becoming more and more pressing. These issues ask for not only changes on a product-level but also on a system-level (Ceshin, 2013). One of the potential solutions can be to facilitate more sustainable consumption. Sustainable consumption patterns can potentially be created by product-service systems (PSSs). PSSs enable “sale-of-use” instead of “sale-of-product” so these systems satisfy consumers through the delivery of functions instead of products. U....................
|| (2019-06-28) Latent Space Modelling of Unsteady Flow Subdomains: Thesis Report|
Mulder, Boris (author)
Very complex flows can be expensive to compute using current CFD techniques. In this thesis, models based on deep learning were used to replace certain parts of the flow domain, with the objective of replacing well-known regions with simplified models to increase efficiency. To keep the error produced by the deep learning model bounded, a traditional CFD model and deep learning model were coupled using a boundary overlap area. In this overlap area, the flow computed by the traditional CFD model ....................
|| (2019-06-27) Bouwteam: For more collaboration in the construction industry|
van Riggelen, Roos (author)
Bouwteam is a collaboration agreement in which the contracor is involved early on to work together with the client to make a design in which the knowledge of the client and the contractor is used optimally. Through the years the Bouwteam has been influenced by integrated contracts and has been changing in a variety of ways. Nowadays, there is not one standard way of using a Bouwteam anymore. In the last decade the Bouwteam has increased in popularity and is being used more and more. The Bouwteam....................
|| (2019-06-26) Internal Loads of Semi-Submersibles at an Inconvenient Draft: An investigation into the non-linear response|
Korte, Ruben (author)
Once a semi-submersible is operating at an inconvenient draft (A shallow draft with limited water column above the pontoons), the passing waves over the pontoons can not keep their linear motion and energy will be transferred to higher harmonic wave frequencies. This means the hydrodynamic response will also contain energy at these higher frequencies. Conventional linear diffraction solvers are not able to solve the combined response of the wave frequency and its higher harmonics, which then res....................

de Vries, Sybren (author)
Although many studies have been performed on porous absorbable iron scaffolds created by the space holder method, no studies have considered the influence of variations in space holders on absorbable scaffolds. The present study aimed to clarify the effects of space holder particle size and volume fraction, on the pore structure, resultant mechanical properties and absorbability of iron scaffolds.
Spherical iron particles were used as the matrix powder and mixed with coarse and fine rectang....................

Gradussen, Bas (author)
River discharge is an essential parameter in morphodynamic modelling. It proves to be highly variable in both time and space. In this thesis the impact of the schematisation of time-dependent discharge series on morphodynamic change is studied. The impact is governed by several factors such as the long-term discharge statistics, and both short- and long-term sequences of discharge stages. A variable river discharge itself does not necessarily result in morphodynamic change. Changes in conveyance....................

Tempel, Auke (author)
Regular maintainance dredging is a large expense to the Port of Rotterdam, therefore the installation of sediment traps is considered. By increasing the bathymetry locally, an increase of local accumulation is expected and a decrease deeper in the harbour basin. This thesis describes the functioning of sediment traps in a stratified tidally energetic estuary, where sediment is supplied by the river and sea. A numerical 2DV representation is set up for the Botlek Harbour with the hydrostatic Delf....................

Kleijn, Sarah (author)
Lately structural safety is an often discussed subject in The Netherlands. Recent collapses have made people question if our buildings are actually safe enough. Research shows that the individual probability of death due to structural failure is below the limit of 10-5 per year. However, it is unknown if every single building is safe enough as well. The main cause of structural failures are human errors (90% of the collapses). However, the Dutch Building Decree does not mention the unidentified ....................

Jutten, Daan (author)
Offshore wind farms are moving to deeper waters, implying that larger substructures will need to be installed. The monopile is the leading substructure nowadays and this structure could be promising for use in deeper waters as well. Generally, jack-up vessels are used for the installation of the substructures and turbines. However, the jacking up and down of these vessels is time-consuming and limiting with regard to the water depth. A solution to tackle these two drawbacks, is to conduct the in....................

Juwita, Adinda Bunga (author)
Multi-material compliant mechanisms have shown the potential to be utilized in the upper-limb prosthesis. The mechanisms consist of flexural and rigid parts, where the flexural components can serve as flexible joints between rigid bodies in the device (e.g., finger and finger segments). This configuration is feasible to be fabricated using a type of additive manufacturing called Fused Deposition Modelling (FDM) process, without the need of further assembly and extensive post-processing.

Bleeker, Cliff (author)
In the energy transition the expansion of the amount of renewable energy resources requires new methods for the design of energy systems. To deal with intermittent energy production, different energy technologies and solutions are in development. Hydrogen is a main candidate for this goal. Using Fuel Cell or Battery Electric Vehicles as flexible power plants is a second potential solution. This thesis explores how these two concepts can be combined in an office environment. The goal was to desig....................

el Hassnaoui, Mounir (author)
Long before humans will completely trust fully automated vehicles, partial and conditional automation where the human driver is still in the loop will dominate the era of autonomous vehicles. However, more than 90% of traffic accidents are due to human errors, of which approximately half appear to be due to perceptual errors. Especially at busy and complex intersections that have a high density of visual stimuli. This poses a high demand for accurate measurement of the driver's situation awarene....................

Bos, Evert (author)
With an in vehicle camera many different things can be done that are essential for ADAS or autonomous driving mode in a vehicle. First, it can be used for detection of general objects, for example cars, cyclists or pedestrians. Secondly, the camera can be used for traffic light recognition, which is localization of traffic light position and traffic light state recognition. No method exists at the moment able to perform general object detection and traffic light recognition at the same time, the....................

van Weperen, Marijke (author)
In recent years, rapid progress has been made towards automated highway driving. To increase comfort and trust in these automated cars, their motion planners, such as Model Predictive Controllers (MPCs), should exhibit a human-like driving style. However the effect of surrounding traffic on overtaking maneuvers has not yet been investigated. Here, the influence of the relative speed between cars and the width of the to-be-overtaken car on overtaking trajectories is analysed. In a driving simulat....................

de Paauw, Marieke (author)
In the Netherlands 1.5% of persons with an intellectual disability have children, most of these parents only have mild intellectual disabilities (Willems, De Vries, Isarin & Reinders, 2007). In practice this means that a few thousand children have parents with a mild intellectual disability (De Vries, 2005). Research shows that there is a limited system capacity to support parents with mild intellectual disabilities (MID). Whereas most other parents can rely on their social network when they....................

Overklift Vaupel Klein, Thomas (author)
University students are expected to study on their own for large amounts of time. However a lot of these hours are not spent effectively by students. Eventually students who have trouble with self-studying in an effective manner may end up failing courses because of this. When students realise they have a (self-study) problem they can seek aid by contacting the academic counsellor. However, there are problems with this workflow: students often need time to acknowledge they are having issues. The....................

van der Klein, Anne (author)
The spherical transform maps the orthogonal basis of symmetric Jacobi-type polynomials to an orthogonal basis of (symmetric) Wilson polynomials. The spherical transform is closely related to the Cherednik-Opdam transform, as it is essentially its symmetric version. The symmetric Jacobi-type polynomials can be composed from the non-symmetric Jacobi-type polynomials. These relations, between the symmetric and non-symmetric theory, give an incentive to consider the Cherednik-Opdam transform of non-....................

Starmans, Ruben (author)
Web shops use recommender systems to help users find the products they find interesting in the large amount of available products online. An often used approach to do so is collaborative filtering. This method relies on historical user-item interactions and uses them to recommends products other users found interesting. Fashion is very reliant on quickly changing trends and personal preferences and requires a more personal and up-to-date approach. The focus of this research is to generate recomm....................

Verstraeten, Dries (author)
The aerospace industry has made the transition from aluminium to carbon fibre composites on the newest, most advanced aircraft. One of the main disadvantages of composites is its high susceptibility to impacts, such as tool drops which occurs on a single point of impact. As such, these types of impact have been thoroughly studied. Nevertheless, a much less studied phenomenon but with possible catastrophic consequences is the effect of impacts covering a large area, such as hail. This research, t....................

Bhoera, Ramkoemar (author)
Global AIS coverage is not possible with terrestrial AIS as base stations are required to be build on sea, which is impractical. With the use of LEO satellites, the field of view of a single receiver is increased and is capable of communicating with many AIS cells simultaneously. As many vessels are transmitting data to the same receiver, message collisions occur which results in data loss.
In order to increase the performance of the AIS receiver, blind beamforming techniques are used. This....................

Teng, Xiang (author)
This work gives a method which can use both motion and shape information for drinking action detection. Drinking action is differ from the other gestures. A complete drinking action duration could be divided into 3 different stages. Motion-based features and shape-based features are complement with each other in each stage. By using this feature, we have defined a fusion strategy that can use both the advantage of the strength of each part at a different stage.
