Chinea Hammecher, Claudia (author)Glioma progression is monitored by routine MR scanning, enabling tumor growth evaluation with respect to earlier time-points. This growth may present both as a mass effect and as an extension of abnormalities into previously healthy tissue. To accurately quantify tumor growth and tumor-induced deformations, longitudinal intrasubject image...master thesis 2022

Ansuinelli, P. (author)The importance of inverse problems is paramount in science and physics because their solution provides information about parameters that cannot be directly observed. This thesis discusses and details the application of a few inverse methods in optical imaging, metrology and inspection of lithographic targets, particularly patterned structures on...doctoral thesis 2022

Pérez, Jesús Vilaboa (author), Loicq, J.J.D. (author)The E-TEST project builds a prototype for the Einstein Telescope (ET). ET is a proposed gravitational-wave observatory. E-TEST includes a silicon mirror of 30 cm up to 40 cm diameter, suspended and cooled down at cryogenic temperatures from 20 K to 30 K. During the cooling down, the mirror will be affected by surface topology changes, wavefront...conference paper 2022

(author), Rentmeester, Marie-Jozé (author), van der Vliet, Marijke (author), Wils, Evert-Jan (author), Ong, David S.Y. (author)Background: The initial aim was to study the effects of face masks worn by recently infected individuals on the airborne spread of SARS-CoV-2, but findings motivated us to proceed with comparing the presence of SARS-CoV-2 in air samples near infected individuals at home with those near infected intensive care unit (ICU) patients. Aim: To...journal article 2022

(author)De totale zorg draagt naar schatting voor 5 tot 8% bij aan de totale CO2-uitstoot in Nederland. Dit wordt mede veroorzaakt door het grote verbruik van medische wegwerpproducten, die na gebruik verbrand worden. Onderzocht is of gebruikte chirurgische mondmaskers gerecycled kunnen worden om nieuwe medische producten te maken. Recyclen kan ervoor...journal article 2022

Vilaboa Pérez, Jesús (author), Georges, Marc (author), Lenaerts, Cédric (author), Loicq, J.J.D. (author)We describe the state of development of a white light interferometer to characterize the cryogenic mirrors for GW detector on operation. We include the first experimental results from the proof of concept of the metrology instrument. The instrument will characterize the topology as well as the vibration of the mirrors. This development takes...conference paper 2022

Stella Mulia, Stella (author)The absence of medicines to cure COVID-19 calls for preventive strategies, including mask-wearing. Despite its protection against exposure to coronavirus, not everyone chooses to wear a mask. Some studies addressed mask-wearing behaviour from the standpoint of behavioural economics, one being the effect of herding behaviour. This occurs when...master thesis 2021

Gîrdianu, Alex (author)There is an increasing demand for a highly accurate weather system on the runway for early detection and warning of severe weather phenomena. Due to the high performances of a phased array radar system in terms of time-resolution and elevation-resolution, an already existing fast-rotating phased array radar, 60 RPM, is studied to find the...master thesis 2021

(author)The use of 3D anthropometric data of children’s heads and faces has great potential in the development of protective gear and medical products that need to provide a close fit in order to function well. Given the lack of detailed data of this kind, the aim of this study is to map the size and shape variation of Dutch children’s heads and...journal article 2021

Ortiz, Marco A. (author), Ghasemieshkaftaki, M. (author), Bluyssen, P.M. (author)Since the outbreak of COVID-19, wearing a mask, voluntary or obligatory, has led to diverse and numerous designs. Guidelines for minimum requirements include tests for visual inspection, strength, filtration, and breathing resistance, but not for the fit of a mask. The fit of a mask was assessed by testing the outward leakage of exhaled...journal article 2021

van Gaalen, Melissa (author)Introduction<br/>Transparent facial pressure masks with silicone sheeting are used as a non-invasive treatment option for hypertrophic scarring following oncological facial reconstruction. These masks are fabricated using conventional plaster moulds, which is labour-intensive and requires an experienced orthotist or prosthetist. 3D scanning and...master thesis 2020

Zwart, Lotte (author), Donkers, Huub (author)The COVID-19 pandemic caused a shortage of Personal Protective Equipment for Healthcare personnel. This project aims to aid in this shortage by extending the lifetime of the filter material used in a mask. This is done in the form of an SPPE, a Smart Personal Protective Equipment. This face mask has two smart filter heads that are modular and...bachelor thesis 2020

Lut, Jasper-Jan (author), Goddijn, Michael (author)The current COVID-19 pandemic shows the necessity of personal protective equipment and face masks. In the project, a filter module with an in-situ ultraviolet-sterilization technique is designed that can serve as a new kind of smart personal protective equipment (SPPE). This technique is not used in wearable devices as of yet. The project thus...bachelor thesis 2020

van der Horst, C.G. (author)In 2019 a virus surfaced in China that would later cause a pandemic: the coronavirus. Across the world measures were taken to reduce the spread of the virus. Public Transport (PT) had a unique position, being both an essential service and a place where the virus can easily be spread. This research investigates the measures taken in PT in the...bachelor thesis 2020
