In dit onderzoek is getracht een non-medicamenteuze interventie te vinden voor het reduceren van acute pijn op de SEH en te onderzoeken in hoeverre alfa binaural beats hierin als interventie kunnen dienen. Uit literatuuronderzoek blijkt dat angst de pijnervaring bij patiënten kan versterken, daarnaast komen alfa frequentie hersengolven voor bij personen die in een ontspannen staat zijn. De hypothese is daarom dat binaural beats met een alfa frequentie een reducerend effect hebben op de state-an....................
|| (2019-09-01) Fixed-term contract jobs|
Fixed-term contracts have become a common tool for employers to screen new employees. There has been widespread debate about the use of this type of contract. However, previous research established that fixed-term contracts can serve as a stepping stone into permanent employment. Consequently, fixed-term employees have the incentive to exert more effort than permanent employees. Using overtime hours and absenteeism as effort measures taken from the Dutch LISS panel, we present evidence that fema....................

Tegenwoordig bestaat er veel discussie rondom de positie van transgenders in de maatschappij. Er
worden verschillende initiatieven ondernomen ten behoeve van genderneutraliteit en daarnaast
groeit de aandacht voor transgenders in de media. Deze mediarepresentaties zijn van invloed op hoe
het publiek tegen transgenders aankijkt en hierover een mening vormt. Ondanks de groeiende
media-aandacht, hebben transgenders nog steeds een ondergeschikte positie in de maatschappij en
worden zij negatief....................
|| (2018-12-06) The quantum advantage to charging electron spin qubit batteries|
Breeman, Emma (author)
Quantum thermodynamics takes over from classical thermodynamics when systems are of the scale of single particles and quantum fluctuations have a noticeable effect. An interesting topic of research of this relatively new field is the quantum battery, which in this thesis consists of an array of N identical electron spin qubits. In an article by Binder et al. , it is proven that in theory, an N-times decrease in charging time of the battery is achieved when global operations on qubits are perm....................

|| (2018-07-30) Scenario Based Approach To Decentralized Stock Distribution: A Royal Netherlands Army case study|
Koffeman, Rutger (author)
Background: Currently the Royal Netherlands Army (RNLA) has a traditional three echelon supply chain consisting of suppliers that deliver to a warehouse and the warehouse that delivers to customers. However, the RNLA is interested in having its stock geographically spread for safety reasons. A solution for this would be to re-design the supply chain into a decentralized stock distribution design. This means that instead of keeping the majority of the stock at a RNLA controlled storage facility, ....................

Soons, Sophie (author)
To control fluid transport, microfluidic systems often make use of pressure driven flow and pneumatically actuated valves. However these require bulky external instrumentation. An integrated fluid control mechanism would make microfluidic systems more portable, closed and automated. The aim of this project was to create a pH-responsive membrane for integrated fluid control in microfluidic systems. pH-responsiveness will allow the membrane to interact directly with analytes in a microfluidic syst....................
|| (2018-07-27) Scaling limits of long-range quantum random walks|
Westdorp, Rik (author)
In this thesis we introduce a variation on the quantum random walk to discuss shifts in an arbitrary range. The concept of Hadamard coin was therefore generalised to a higher order. By a Fourier transform method and a tensor product decomposition of the evolution matrix the long-range quantum random walk was found to converge in distribution to a random variable, different for every range. The limiting random variable consists of three parts: one part fast decaying with the range size, a non-con....................

Schmidt, Julia (author)
Synthetic polymers, in the emulsified form, have been utilized for enhanced oil recovery applications by using saline make-up water. However, there are concerns that have been raised about their injectivity. The large entangled polymer chains can clog the pore throats, giving a tendency to cause injectivity reduction. In this study, processing techniques were used to condition an acrylamide-based copolymer inverse emulsion system at a salinity of 50,000 ppm TDS before being injected into porous ....................
|| (2018-07-24) Pile tip deformation caused by obstacles|
Jorna, Menno (author)
Monopiles will be installed in more difficult terrain since space in the 'ideal' locations is reduced by the rapidly increasing development of wind farms in the ideal areas. In difficult terrain, the amount of obstacles or hard layers increase, leading to an increased risk of pile tip damage. Also the ever increasing D/t ratio of the pile leads to piles more vulnerable to damage to the pile tip. Already, damage to the pile tip was encountered in projects such as the Goodwyn A and Valhall project....................
|| (2018-07-23) Numerical study of adaptive mesh refinement applied to a third order minimum truncation error Active Flux method|
Kunnen, Jeroen (author)
In 2011 a relatively new type of numerical scheme has been introduced: Active Flux schemes. In this type of scheme an extra degree of freedom is added to the cell interfaces of a regular finite volume grid. This enables the use of non-conservative update methods for these additional variables, as conservation is automatically adhered to by the cell integral values. This increases the order of accuracy of the scheme, while allowing a broader range of update methods. This thesis proposes a new upd....................
|| (2018-07-23) A Low-Power CMOS Wind Sensor|
van der Kruijt, Arjan (author)
This work describes a low-power and low-cost alternative to mechanical wind sensors, suitable for volume production in standard CMOS processes. The CMOS wind sensor operates in the electro-thermal domain; therefore, it has no moving parts and therefore requires very little maintenance. Moreover, the CMOS wind sensor is an active sensor, compared to its mechanical counterpart. Its sensitivity can be easily adjusted by changing the magnitude of the excitation signal.
Despite the manufactu....................

Mandersloot, Jeroen (author)
Rare category detection is the task of discovering rare classes in unlabelled and imbalanced datasets. Existing algorithms focus almost exclusively on static data in which instances are assumed to be independent. In this thesis we propose an algorithm that is designed for temporal data. Specifically, we are interested in data with temporal smoothness, i.e. where consecutive instances likely belong to the same class. We use the task of bird song detection in outdoor audio recordings as a motivati....................

Feys, Charles (author)
A specific type of wave is identified as an infragravity wave (IG wave). These waves with very long wave periods, even up to minutes, are possibly dangerous for flood events, increased storm surge and/or failure of coastal defences. Current guidelines for dike safety are often determined for gravity wave dominated systems, so identifying IG dominated systems can be a tool to determine whether dike safety guidelines are sufficient or not. To analyse the IG waves, the non-hydrostatic simulation mo....................

Du, Jingling (author)
In the Netherlands - and indeed most of the Western world - the prospect of a shrinking population and decreasing economic growth appear to be the most pressing issues. Town planning can greatly contribute to a more sustainable world, and the means it needs to do so are at the heart of the discipline, in the form of rational zoning, that is, the design of urban patterns that minimize the need for traffic. "Densification" is often promoted as a means to achieve this - though, obviously, everythin....................
