Towards Circular Batteries: Investigating Particle-Size Based Separation of Active Materials from spent Li-ion batteries

With the enormous growth of portable electronics and the market expansion of electric vehicles, the demand for lithium-ion batteries is increasing enormously. To meet this demand, efficient recovery of battery components becomes crucial. Graphite, the material of choice for lithium-ion battery anodes, faces significant supply risks as current...

Understanding Drivers' Lane Choice Behavior at Pre-Signalized Intersections: Examining Implications for Efficiency and Applicability of Pre-Signal Use for Regular Traffic

In the face of urbanization and limited space, traffic management grapples with challenges, especially heavy left-turn volumes at signalized intersections. The pre-signal strategy, proposed by Li et al. (2014), emerges as a promising solution. It involves an additional traffic light upstream of the main intersection, creating a "sorted area"...

Development of the Experimental Design for the Validation of EEG Source Localization with fMRI: Application of a Haptic Robot to Identify Active Neuronal Ensembles

Various source localization algorithms exist to perform localization with High Density (HD)-ElectroEncephaloGraphy (EEG). However, validation of these EEG source localization algorithms is lacking. The current gold standard for source localization in the brain is functional Magnetic Resonance Imaging (fMRI) by calculating the difference in...

Optimization of nurse scheduling satisfaction

A recent study in The Netherlands, reports an expected shortage of 140,000 healthcare employees by 2031. Two main reasons for this shortage are an increased demand for healthcare and a shortage on the healthcare labour market. The irregular shifts and unconventional working hours make nurses quit their profession or refrain others from applying....

Modelling an upend hinge in hydrodynamic simulations of a monopile upend operation

The offshore wind energy industry is quite literally reaching for the sky to meet the increasing demand for renewable energy in Europe. Offshore wind turbines are sprouting out of the waves off the coast of many European nations and their size is increasing rapidly. As the turbines become larger and the waters in which they are placed become...

Peer Learning en Succescriteria: Leerlingen helpen bij het beantwoorden van de vraagstukken ‘Waar moet ik heen?’ en ‘Waar sta ik nu?’

Het doel van dit onderzoek is om leerlingen te helpen bij het beantwoorden van de vragen ‘Waar moet ik heen?’ en ‘Waar sta ik nu?’ en gaandeweg factoren ontdekken die leerlingen hierbij belemmeren. De eerstgenoemde vraag gaat over het deel van het leerproces waarin leerlingen een compleet beeldmoeten vormen van de eindtermen...

Dynamic Contact Angle measurement using microfluidic experiments relevant for Hydrogen Subsurface Storage

Underground Hydrogen storage (UHS) is an attractive technology for large-scale energy storage. The UHS safety and efficiency depends highly on accurate characterization of H2 interactions with reservoir fluids, specially wettability analyses for H2/brine/rock systems. This thesis reports experimental measurements of advancing and receding...

On the Development of a Lens Phased-Array at 100GHz

This thesis is concerned with a first time demonstration of a high frequency scanning lens phased­-array with dynamic steering. Such phased­-array could provide the high gain, wide bandwidth, and steering capability that the next generation of wireless ap­plications requires. The phased-­array development was divided into three distinct parts....

Spread-based Stochastic High Frequency Railway Optimization

This paper outlines a mathematical model for the creation of a robust timetable for the optimization of the lightrail network in Rotterdam and The Hague. A novel spread-based goal function focuses on minimizing wait time as opposed to delay. The situation is modeled as a Quadratic Stochastic Programming problem, and solved by employing Monte...

Personalized Automation for Air Traffic Control using Convolutional Neural Networks

In the upcoming years, en route airspace capacity will be limited by air traffic controller workload, requiring the introduction of automation to assist controllers with conflict detection and resolution. However, acceptance is considered to be one of the main obstacles in the introduction of novel automation. Individual-sensitive automation has...

Uncertainty Analysis of Thermal Recharge by Free Convection in Geothermal Reservoirs

This study investigates the thermal recharge of deep geothermal reservoirs by free convection. A coupled numerical model that is built in Comsol Multiphysics is presented in order to estimate the thermal recharge during the first 30 years of production from a typical high enthalpy geothermal reservoir. A sensitivity analysis was carried out to...

Integration of a layer picking area with the OptilogX Sequencing Buffer

The current automated warehousing solution from ORTEC is handling order pallets without changing its layer configuration. However, a warehouse can be used to handle different order pallet types. This paper shows the requirements for and the feasibility of integrating a layer picking area with the automated warehousing solution. A layer picking...

The effect of small density differences at large confluences

Confluences are special, complex elements within river systems which have been subject of much research. However, little attention has been given to the effects of density differences in confluences. The aim of this research is to see when and how density differences are important in confluences with respect to other occurring flow structures....
