Active small-scale space debris removal by a space-based laser

Space debris objects with sizes between 1 and 10 cm form the greatest risks for creating new collisions with active spacecraft as they are too small to track and too large to be shielded against. This research has simulated the performance of a space-based laser system on the removal of these small-scale debris objects. The selected system is...

Het uitbreidingsprobleem voor continue selecties met paracompact Hausdorff-domeinen

In dit artikel kijken we naar het uitbreidingsprobleem voor continue selecties.<br/>Het uitbreidingsprobleem in het algemeen vraagt of, gegeven een domein, elke<br/>continue functie op een gesloten deelverzameling van dat domein, uitgebreid<br/>kan worden tot een continue functie op heel het domein. We kijken in dit<br/>artikel echter in het...

Designing an entertaining game for children that measures their social/emotional development

In order to support the development of children, they are continuously monitored at all types of care they go to. The goal of SWKGroep is to improve this support of the development. In order to do this, and enrich their portfolio, they want to know the possibilities of measuring the development with the use of a physical game. <br/><br/>This...

Morality in the preference for Advanced Driver Assistance Systems: Identifying the importance of safety for other road users in consumers preference for extra car features

This research examines the incorporation of morality in discrete choice modelling, applied to the specific case of the choice for ADAS in lease cars. Implicitly, the decision to include or exclude ADAS in a car affects the safety of the driver himself and other road users. Therefore this decision has a moral dimension; a moral dilemma arises...

Flight Simulator Benchmarking: A Simulator Comparison Study into the Effects of Motion Filter Order on Pilot Control Behavior

This thesis describes an experiment investigating the effects of motion filter order on human manual control tracking behavior and performance. The experiment was performed on two simulators: the Vertical Motion Simulator at NASA Ames Research Center and the SIMONA Research Simulator at Delft University of Technology. Eighteen pilots in the...

Misalignment Tolerant Inductive Power Transfer (IPT) Systems: System analysis and controller design

This report contains the design and implementation of two control systems related to an inductive power transfer system. This IPT system charges a battery at maximumefficiency and constant power using a buck converter. A linear controller has been designed around the buck converter and implemented on a FPGA tomatch impedance for maximum...

Motion Compensation on Fast Crew Vessels: Concept Design and Technical Feasibility

Due to global demand for safe and cost-effective offshore personnel transfers, Ampelmann has developed multiple-motion-compensated transfer systems. These vessel-mounted motion-compensated offshore transfer systems allow for safe and comfortable access from vessels onto offshore structures. These systems create a near-motionless transfer deck by...

Towards one planet sport events

My graduation covers an inquiry into sustainability assessment and procurement for outdoor sport events and the function of the built environment to facilitate these specific temporary urban interventions. The research was used and tested on the World Rowing Championship that are organized in Amsterdam in August 2014. This research was used as a...

The air cargo supply chain at Schiphol, process improvement and collaboration

Schiphol, the main airport of the Netherlands, wants to be Europe’s preferred cargo airport. To reach this status, Schiphol has to offer a good infrastructure and high quality processes. Schiphol has no active role in these processes, but is dependent on third parties. Schiphol suffers from inefficiencies in the air cargo supply chain. A symptom...

Transformation Zero: From office towards an energy-neutral residential building

With this master thesis, the possibilities are explored to transform the former tax office in Utrecht towards an energy neutral residential building. The Dutch office market is facing a structural vacancy of 4.2 million square meter, that will even increase in the coming decades due to new ways of organizing labour, such as: flex working. The...

The new Insider for BR-ND

This project has been carried out on behalf of branding agency BR-ND, aiming at redesigning BR-ND’s Insider tool to fit the changing market. The Insider tool is used to gain input and engage the organisation during brand innovation processes; a process performed by BR-ND together with a client to renew a brand on one or multiple aspects such as...

Influence of hydrogen addition to argon shielding gas on arc characteristics and weld bead geometry

The addition of hydrogen to argon shielding gas in welding stainless steel has the advantage that the penetration increases, due to which a higher welding speed can be obtained. The objective of the study presented in this report is to provide a better understanding of the influence of hydrogen on arc characteristics, heat input and bead...

Mass transport in gravity waves on a sloping bottom

Summary of the graduation work published at the ICCE: In the present investigation the influence of bottom slope on mass transport by progressive waves was investigated, both theoretically and experimentally. Theoretical considerations based on linear wave theory show the greatest influence of the slope on the bottom drift velocities for...
