Wagenaar, Britt (author)The Netherlands is experiencing a significant increase in its aging population. Multi morbidity and a rapidly growing shortage of healthcare personnel are putting pressure on the healthcare system, leading to capacity issues. The capacity problems of care have medical, safety, social, and economic consequences. Policy measures are needed to...master thesis 2023

Wagenaar, Thomas (author)While physics-informed neural networks have been shown to accurately solve a wide range of fluid dynamics problems, their effectivity on highly compressible flows is so far limited. In particular, they struggle with transonic and supersonic problems that involve discontinuities such as shocks. While there have been multiple efforts to alleviate...master thesis 2023

Kok, M. (author), Slager, Kymo (author), de Moel, Hans (author), Botzen, Wouter (author), de Bruijn, Karin (author), Wagenaar, Dennis (author), Rikkert, S.J.H. (author), Koks, Elco (author), van Ginkel, Kees (author)The floods in the Netherlands in the summer of 2021 led to severe economic damage and losses in the affected area. A first estimate in September 2021 showed that more than 2,500 houses, more than 5,000 inhabitants and around 600 businesses were affected. Using the Dutch standard Flood Damage and Loss Model (SSM2017), and based on figures from...journal article 2023

(author)Post-war urban neighbourhoods in industrialised countries have been shown to negatively affect the lifestyles of their residents due to their design. This study aims at developing an empirical procedure to select locations to be redesigned and the determinants of health at stake in these locations, with involvement of residents’ perspectives...journal article 2023

Groenevelt, W.G.M. (author), Wagenaar, C.C.M.L. (author)An algebra is introduced which can be considered as a rank 2 extension of the Askey–Wilson algebra. Relations in this algebra are motivated by relations between coproducts of twisted primitive elements in the two-fold tensor product of the quantum algebra U<sub>q</sub> (sl(2, C)). It is shown that bivariate q-Racah polynomials appear as...journal article 2023

Zhang, Yufang (author), van Dijk, Terry (author), Wagenaar, C. (author)Promoting adequate physical activity (PA) such as walking and cycling is essential to cope with the global health challenge of non-communicable diseases (NCDs). Much research has been conducted to analyze how the built environment can promote PA, but the results are not consistent. Some scholars found that certain built environments such as...journal article 2022

(author)In gas fermentations (using O2, CO, H2, CH4 or CO2), gas-to-liquid mass transfer is often regarded as one of the limiting processes. However, it is widely known that components in fermentation broths (e.g., salts, biomass, proteins, antifoam, and organic products such as alcohols and acids) have tremendous impact on the volumetric mass transfer...journal article 2022

(author), Wagenaar, Cor (author)Physical activity is good for people’s health. The relationship between the built environment and physical activity has been well documented. However, evidence is both scarce and scattered on specific urban interventions, i.e., intentional redesigns of the built environment that promote physical activity accompanied by pre- and post-effect...review 2022

Wagenaar, Kirsten (author)To this day, liver transplantation is the only effective treatment for end-stage liver failure. Unfortunately, the scarcity of liver donors leads to waitlist mortality, pushing the need for alternative treatment options. In vitro models are essential tools in research on alternatives for transplantation. One of the promising models is the...master thesis 2021

Wagenaar, Carel (author)In this thesis, we introduce the quantum groups Uq(SL(2,C)) and Aq(SL(2,C)) as Hopf algebras. We study their representations, including their similarities and differences with the classical theory. We show that the eigenvectors of Koorwinder's twisted primitive elements of Uq(SU(2)) are dual q-Krawtchouk polynomials. We use this explicit...master thesis 2021

Wagenaar, S. (author), Infante Ferreira, C.A. (author)Within the agriculture sector, drying of food and flowering products is a required production step. Most companies use hot air dryers where the heat is obtained by combustion of natural gas. This paper proposes a heat pump assisted drying system as an alternative. Flower bulb carrying boxes containing just harvested products have been...conference paper 2021

Schubert, Dirk (author), Wagenaar, C. (author), Hein, C.M. (author)Port cities have long played a key role in the development, discovery, and fight against diseases. They have been laboratories for policies to address public health issues. Diseases reached port cities through maritime exchanges, and the bubonic plague is a key example. Port city residents’ close contact with water further increased the chance...journal article 2021

Wagenaar, Danielle (author)The urban mobility sector is developing at a fast pace and is demanding transportation systems to be resilient and sustainable. Policy makers deal with an extensive offer of new technologies but lack an overview of the contribution of these mobility solutions to their urban planning ambitions. Uncertainty exists regarding both the technological...master thesis 2020

Wagenaar, Claire (author)In this thesis, several image segmentation techniques will be tested that eventually will be applied to MRI brain scans in order to detect hydrocephalus. The meth- ods include Sobel edge detection, Canny edge detection, active contour model (also known as snakes), k-means clustering and region growing. Furthermore two exten- sions are discussed....bachelor thesis 2020

Wagenaar, Sjors (author)In some countries, drying processes use up to 20% of the total energy consumption. Within the agriculture sector, drying of food and flowering products is a necessary step in production. A lot of companies make use of hot air dryers where the heat is gained by burning natural gas. A novel method is to use a heat pump assisted drying systems...master thesis 2019
