van Beek, Max (author)In recent decades Europe has been increasing its demand and consumption of electronics. This has in turn resulted in major outflows of waste electronics (WEEE) that are usually not properly dealt with. This is especially the case for low to medium grade printed circuit boards (PCBs) which unlike higher grade electronics such as computers are...master thesis 2022

Smeets, Lucy (author)Sorting systems form an example of event driven systems. These types of systems are referred to as discrete event systems (DES), and they consist of jobs that need to be performed at available resources. In an autonomous sorting system, jobs consist of robots receiving and delivering parcels at the correct locations. With scheduling, optimal...master thesis 2022

Beekman, Elwin (author)Background: With around 70 supermarkets, Hoogvliet is one of the smaller supermarkets in the Netherlands. During the past years, more companies have become aware of the importance of efficient reversed logistics (Senthil et al., 2018). By optimizing this return flow, the return hall of supermarkets plays an important role. With the expected...master thesis 2022

van Wolfswinkel, Lotte (author)Starting from the 1950s, plastic has found its way into many aspects of life; from packaging to transportation and construction. The annual global plastic production was estimated to be 330 million metric tons in 2017 and will be doubled within 20 years if the current growth rate persists. In Europe, packaging accounts for 40% of the annual...master thesis 2022

Megevand, B.P.N. (author), Cao, Wen-Jun (author), Di Maio, F. (author), Rem, P.C. (author)This paper aims to summarize, propose, and discuss existing or emerging strategies to shift towards a circular economy of materials. To clarify the landscape of existing circular practices, a new spectrum is proposed, from product-based strategies, where entire products go through several life cycles without being reprocessed, to material-based...journal article 2022

Coastal aeolian sediment transport in an active bed surface layer: Tracer study and conceptual modelUphues, Charlotte F.K. (author), van IJzendoorn, C.O. (author), Hallin, E.C. (author), Pearson, S.G. (author), van Prooijen, Bram (author), Miot da Silva, Graziela (author), de Vries, S. (author)Coastal aeolian sediment transport is influenced by supply-limiting factors caused by sediment sorting by grain size. Sorting processes can lead to coarsening of the bed surface and influence the formation of aeolian ripples. However, the influence sorting processes and bedforms might have on the magnitude of the transport is not fully...journal article 2022

Kawasaki, S. (author), Yeh, Jia-Jun (author), Saccher, M. (author), Li, Jian (author), Dekker, R. (author)The main limitation of acoustic particle separation for microfluidic application is its low sorting efficiency. This is due to the weak coupling of surface acoustic waves (SAWs) into the microchannel. In this work, we demonstrate bulk acoustic wave (BAW) particle sorting using capacitive micromachined ultrasonic transducers (CMUTs) for the first...conference paper 2022

Biersteker, Erwin (author), van Marrewijk, A.H. (author), Koppenjan, Joop (author)Recently, scholars have called for a focus on subjective aspects of risk management as a suitable lens for understanding how it functions. In line with this lens, this study focuses on project actors’ viewpoints on risk management in the context of construction projects to provide novel insights in risk management. Drawing on Renn's model and...journal article 2022

Piltz, Gunilla (author)Municipal solid waste incineration (MSWI) bottom ash is a by-product of Waste-to-Energy recycling and has until today been used for construction purpose or been landfilled. Especially in the Netherlands the regulatory regime constantly changes and increases the applicability of novel materials from MSWI in construction. Due to the Green Deal a...master thesis 2021

Ahmad, T. (author), Al-Ars, Z. (author), Hofstee, H.P. (author)Background Recently many new deep learning–based variant-calling methods like DeepVariant have emerged as more accurate compared with conventional variant-calling algorithms such as GATK HaplotypeCaller, Sterlka2, and Freebayes albeit at higher computational costs. Therefore, there is a need for more scalable and higher performance workflows of...review 2021

Boot, R.C. (author), Koenderink, G.H. (author), Boukany, P. (author)Spheroids are widely used in vitro 3D multicellular model systems that mimic complex physiological microenvironments of tissues. As different cell types vary in deformability and adhesion, the choice of (heterogeneous) cell composition will define overall spheroid mechanics, including their viscoelasticity and effective surface tension. These...review 2021

Wen, P. (author), Lohlefink, C.G.K. (author), Rem, P.C. (author)Can random deposition create dense non-overlapping material feeding? The question is very fundamental for the research of particle packing, while the answer is of great importance for any industrial process that applies single object operation. To gain an insight into this issue, we studied the overlap problems of convex particles in the...journal article 2021

Hester, Thomas (author)This thesis contains the design process of a compliant shape adaptive chicory gripper for robotic sorting processes. The robotic sorting line consists of an input and output conveyor-belt. The input line contains unsorted chicories which are scanned by a robotic vision system. Overhead FlexPicker robots, equipped with chicory grippers, sort the...master thesis 2020

Ma, Chengxin (author)Variant calling is a classic example of DNA data analysis, in which variants from DNA sequence data are identified. In recent years, a number of frameworks have been developed for implementing the variant calling pipeline. As a result, deeper scientific insights have been gained into genomics. From the computational point of view, however, these...master thesis 2020

Hinlopen, Daan (author)As more people are moving towards urban environments, cities are under pressure and are becoming more dense. Cities are reaching their physical boundaries, limiting the possibilities for horizontal expansion. Solutions towards the problem of densification of cities such as tall buildings are becoming increasingly popular. Existing urban economic...master thesis 2020

Feenstra, Bastiaan (author)In this thesis we explore the acceleration of sorting algorithms on FPGAs using high bandwidth memory (HBM). The target application is an FPGA as an accelerator in an OpenCAPI enabled system, that enables the accelerator to access main memory of the host at a bandwidth of 25 GB/s for either read or write. We explore under what read and write...master thesis 2020

(author)Modern and ancient analogues are often consulted by geologists to help understand subsurface systems. While modern analogues provide information on the areal relationship between facies, ancient systems provide detailed data on the vertical facies variations, typically along a two-dimensional outcrop. Combining data from modern and ancient...journal article 2020
