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....................

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....................

Rajora, Aviral (author)
Heat transfer in multiphase flows plays an important role in many industrial applications. For instance, particle-based solar receivers utilize the high absorptivity and heat capacity of dispersed phase in a carrier fluid to improve efficiency and heat transfer. This dispersed phase generally consists of a large number of small particles. It is, therefore, difficult to completely resolve such flows considering their finite size. Usually, these particles are so small, that they can be treated as ....................

Bhosale, Parag (author)
Currently, non-rigid image registration algorithms are too time intensive to use in time-critical applications. To solve this problem, stochastic gradient descent (SGD) has been implemented in image registration. But, SGD depends on manual step size selection which is dicult and time consuming. To avoid such manual selection, SGD has been improved further by using adaptive stochastic gradient descent (ASGD) and fast adaptive stochastic gradient descent (FASGD) to select an optimal step size auto....................

Nejad, Reza (author)
Extreme folding damage of open-ended tubular piles could occur during piling in onshore practices. Amazonehaven unique quay wall removal gave the opportunity to study king pile’s failure close to toe. King piles are primary piles in a combined wall system, exposed to static and dynamic load. It is argued that the unexpected pile toe failure have been caused by dynamic load because of the uniaxial direction of the extreme deformations. However, research into pile toe failure in Amazonehaven sho....................

Buijs, Roderick (author)
When working offshore on a floating vessel, the vessel will be subjected to wave induced motions and with a moving crane tip, a suspended load can start to swing. When the motions of the load become too large, the operation is interrupted. Alternatives such as jack-ups, function as a fixed platform to which the crane is attached, therefore eliminating the effect of waves on the workability of the vessel. Within the offshore wind industry, jack-ups are used for installation and maintenance of win....................

de Hoop, Stephan (author)
Under-sampling of the subsurface combined with scale differences in observations causes the estimation of geological parameters to be an ill-posed problem. As a result, only a subset of theoretically possible models can truly depict the reality. In reservoir modeling, we capture complexity and heterogeneity by representing the solution space with a large number of high-resolution models, whose spread represents uncertainties in permeability. It is not immediately evident at which scale the stati....................
