Sluijs, Peer (author)Thin-film amorphous Silicon (a-Si) technology has been up and coming in recent years in order to achieve an efficiency comparable to crystalline Silicon (c-Si). Although the technology has existed for quite some time, it has not been researched as much as its crystalline counterpart, especially not in the hotspot reliability sector. The hotspot...master thesis 2023

KODALI, RAHUL (author)This thesis presents experimental research on a phenomenon that has been widely observed in photovoltaic systems in recent years. Hot-spots, most commonly reported as areas of extreme temperature within PV modules, have been identified as a critical issue in the industry. This is primarily due to the fact that solar cells are subjected to...master thesis 2023

Bahlmann, Job (author)This project aims to develop an easy-to-use method to (re)design products for ease of disassembly and subsequently for circular strategies, such as repair, refurbish, remanufacture, etc. Improving repairability is one of the first steps in decreasing the environmental impact of products by prolonging their technical lifespan. This thesis focuses...master thesis 2023

Ranjan, R. (author), Chen, Z. (author), Ayas, C. (author), Langelaar, M. (author), van Keulen, A. (author)Overheating is a major issue especially in metal Additive Manufacturing (AM) processes, leading to poor surface quality, lack of dimensional precision, inferior performance and/or build failures. A 3D density-based topology optimization (TO) method is presented which addresses the issue of local overheating during metal AM. This is achieved...journal article 2023

(author), Jonkers, H.M. (author)This study presents an early-stage design exploration of NRG-Foam, an innovative insulation material composed of cementitious foam doped with microencapsulated phase change materials (MPCMs). The study comprises the static part that utilizes life cycle assessment and life cycle costing assessment for getting insight into the impacts of the...journal article 2023

Hunfeld, Nicole (author), Diehl, J.C. (author), Timmermann, Maarten (author), van Exter, Pieter (author), Bouwens, Joris (author), Browne-Wilkinson, Savanna (author), de Planque, Nine (author), Gommers, D.A.M.P.J. (author)Purpose: The healthcare sector is responsible for 6–7% of CO<sub>2</sub> emissions. The intensive care unit (ICU) contributes to these CO<sub>2</sub> emissions and a shift from a linear system to a circular system is needed. The aim of our research was to perform a material flow analysis (MFA) in an academic ICU. Secondary aims were to obtain...journal article 2022

Banet, Krystian (author), Naumov, Vitalii (author), Kucharski, R.M. (author)We demonstrate how digital traces of city-bike trips may become useful to identify urban space attractiveness. We exploit their unique feature–stopovers: short, non-traffic-related stops made by cyclists during their trips. As we demonstrate with the case study of Kraków (Poland), when applied to a big dataset, meaningful patterns appear, with...journal article 2022

Tsui, T.P.Y. (author), Derumigny, Alexis (author), Peck, David (author), van Timmeren, A. (author), Wandl, Alex (author)In recent years, implementing a circular economy in cities has been considered by policy makers as a potential solution for achieving sustainability. Existing literature on circular cities is mainly focused on two perspectives: urban governance and urban metabolism. Both these perspectives, to some extent, miss an understanding of space. A...journal article 2022

Commandeur, Joost (author)In this thesis BRIGHT, a multi-objective evolutionary algorithm for the creation of treatment plans for high-dose rate brachytherapy for prostate cancer, is extended with a new objective to mitigate the formation of high dose contiguous volumes, i.e. hotspots. Multiple new objectives are tested on their performance to reduce hotspots, while...master thesis 2021

Huisman, Jeroen (author)A compliant mechanism (CM) is a special kind of mechanism which has seen an increase in use in various high-tech applications. A CM is a structure designed with the intention to deform: motion is achieved by deformation of flexible members of its body. CMs are designed by topology optimization (TO) algorithms, which use boundary conditions as an...master thesis 2021

Pena Pereira, Simon (author), PAVLIDOU, ANDRONIKI (author), PANTELIOS, KONSTANTINOS (author), Kountouri, Pinelopi (author), Meschin, Katrin (author), Geers, Lisa (author)The plastic pollution of aquatic environment is undoubtedly an emerging environmental risk, as it negatively affects ecosystems globally to a great extent. To prevent the plastic soup from growing even further, a Delft-based start-up Noria has developed plastic collectors, to remove plastic from rivers and canals before it reaches the ocean. In...student report 2021

Speksnijder, Rogier (author)Intensive urbanisation enhances warming of cities’ ambient and subsoil environment. The local drinking water distribution system (DWDS) is likewise affected. Hotspots of anthropogenic heating were perceived to influence drinking water temperature and pose a threat for microbial drinking water quality. Information on temporal and spatial relation...master thesis 2021

Zheng, Zhenqi (author), Xiao, Xiongwu (author), Zhong, Zhi Chao (author), Zang, Y. (author), Yang, Nan (author), Tu, Jianguang (author), Li, Deren (author)Digital Elevation Model (DEM)-based mountain vertex extraction is one of the most useful DEM applications, providing important information to properly characterize topographic features. Current vertex-extraction techniques have considerable limitations, such as yielding low-accuracy results and generating false mountain vertices. To overcome...journal article 2021

(author), Blokker, E.J.M. (author)Water temperature is often monitored at water sources and treatment works; however, there is limited monitoring of the water temperature in the drinking water distribution system (DWDS), despite a known impact on physical, chemical and microbial reactions which impact water quality. A key parameter influencing drinking water temperature is...review 2020

Afghari, A.P. (author), Haque, Md Mazharul (author), Washington, Simon (author)Both crash count and severity are thought to quantify crash risk at defined transport network locations (e.g. intersections, a particulate section of highway, etc.). Crash count is a measure of the likelihood of occurring a potential harmful event, whereas crash severity is a measure of the societal impact and harm to the society. As the...journal article 2020
