Lighting can have a significant influence on product appearance, and therefore on product perception. Multiple studies showed this influence of retail lighting (e.g. Baker et al., 1992; Quartier et al., 2014b). However, existing research into the influence of lighting on product perception is somewhat insufficient, therefore the goal was to gain...

The Innovative Effector Concept (ICE) aircraft model is a high performance aircraft. The aircraft is over-actuated and a new control allocation algorithm has been designed previously to control this aircraft effectively: Incremental Nonlinear Control Allocation (INCA). It is unknown to what degree effector failures will affect the aircraft...

The Submerged Floating Tunnel (SFT), also called an Archimedes Bridge, is a state of the art solution for crossing deep and large waters. The concept of a SFT has been around for many decades. However, none has still been build up till today. A general literature study showed a number of ‘blank spots’ which still need to be researched before...

A new method is presented to estimate average diffuse aquifer recharge of water table aquifers in temperate climates using time series analysis of water table level fluctuations. An accurate estimate of the recharge caused by rainfall requires an accurate estimate of the influence of evaporation. In temperate climates, evaporation imprints a...

A new analytic solution is presented for tidal propagation in multilayer coastal aquifers consisting of an arbitrary number of layers. The solution is derived using matrix calculus and may be applied to simulate tidal propagation in systems where aquifer layers are separated by leaky layers of low permeability or in stratified aquifers. The head...

Additive manufacturing, also known as 3D printing, is acknowledged for its potential to support sustainable design. In this paper, we explore whether the opportunities that additive manufacturing offers for sustainable design are also useful when designing for a circular economy, and to what extent additive manufacturing can support design...

An approach is presented to determine groundwater flow in unconsolidated aquifers with a heat pulse response test using a heating cable and a fiber-optic cable. The cables are installed together using direct push so that the cables are in direct contact with the aquifer. The temperature response is measured for multiple days along the fiber...

Time series analysis is applied to identify and analyze a transition in the groundwater regime in the aquifer below the sand ridge of Salland in the Netherlands, where groundwater regime refers to the range of head variations throughout the seasons. Standard time series analysis revealed a discrepancy between modeled and observed heads in...

Kitepower is a start up that generates energy using kites. The Kitepower system consists of airborne components, and a ground station where a drum is connected to a generator/electrical motor. For generating energy a so called pumping cycle is performed. In a pumping cycle energy is generated during the traction phase when the kite pulls the...

Research on laser communication technology for satellites has led to a sufficient understanding of this technology to start working on commercial applications. In this work a design is proposed for a lasercom system for CubeSats, a type of nanosatellites that is used increasingly often for commercial missions. The goal of this design is to offer...

This thesis focuses on the Klein Vaticaan area of Zutphen. The Klein Vaticaan was part of the Roman Catholic community within Zutphen, and consisted of an ensemble of buildings located in the neighborhood of the Nieuwstad. The Klein Vaticaan grew significantly throughout the years; at its peak it was roughly the whole eastern part of the...

An approach is presented to determine the seasonal variations in travel time in a bank filtration system using a passive heat tracer test. The temperature in the aquifer varies seasonally because of temperature variations of the infiltrating surface water and at the soil surface. Temperature was measured with distributed temperature sensing...

Increasing complexity of projects is mentioned as one of the reasons for project failure—still. This paper presents a comparative research to investigate how project complexity was perceived by project practitioners in different industry sectors. Five sectors were included: process industry, construction industry, ICT, high-tech product...

Value creation in a circular economy is based on products being returned after use. In the case of smartphones, most are never returned and tend to be kept in drawers. Smartphone access services (e.g., leasing or upgrade) have been experimented with in the Netherlands but have been largely unsuccessful. This study explores the reasons why...

Recently, a monolithic scintillator detector for time-of-flight (TOF)/depth-of-interaction (DOI) positron emission tomography (PET) was developed. It has a detector spatial resolution of ∼1.7 mm full-width-at-half-maximum (FWHM), a coincidence resolving time (CRT) of ∼215 ps FWHM, and ∼4.7 mm FWHM DOI resolution. Here, we demonstrate, for the...

This paper studies estimation of reach probability for a generalized stochastic hybrid system (GSHS). For diffusion processes a well-developed approach in reach probability estimation is to introduce a suitable factorization of the reach probability and then to estimate these factors through simulation of an Interacting Particle System (IPS)....

The framework of design for the circular economy is increasingly used in industry to improve product sustainability and decrease costs, and in academia various models have been developed to guide circular design. However, in the medical sector, although it generates a large amount of waste, application of circular design principles is...

This paper explores the use of annotated portfolios as a method to support the qualitative analysis of interview data about design projects. Annotated portfolios have so far been used to support artefacts with text in order to discuss them in the context of ‘research through design’ In this paper, we interpret the five-step method of McCracken...

In the transition to a circular economy companies are exploring new business models, implying a shift from selling products to offering products in circular business models, such as leasing.
Product design is thought to play a crucial role in enabling this. Having a robust overview of relevant design roles and competencies is of foundational...
