Post, Hanneke (author)The pressure on healthcare systems is increasing all over the world. With an ageing world population, the costs for healthcare and the shortages in medical staff are continually increasing. In the Netherlands, out-of-hours general practitioner departments, or ‘huisartsenposten’, suffer from this increasing pressure in their telephone triage...master thesis 2021

Slagmoolen, Daan (author)Ongoing sea level rise combined with significant levels of land subsidence cause the everlasting need for reinforcements of the current coastal protection measures to ensure a certain level of coastal safety. Developing countries in the Asian regions tend to suffer from even more severe levels of land subsidence and often lack the financial...master thesis 2021

Sabbadini, A. (author)Diastolic heart failure is one of the principal causes of death in Western countries, and there is currently no treatment available; prevention, on the other hand, may be possible, provided an early enough diagnosis. The worsening of diastolic functionality is associated with increased values of cardiac stiffness, which could therefore provide a...doctoral thesis 2021

OUYANG, Boya (author), LI, Yuhai (author), SONG, Yu (author), WU, Feishu (author), YU, Huizi (author), WANG, Yongzhe (author), BAUCHY, Mathieu (author), SANT, Gaurav (author)Despite previous efforts to relate concrete proportioning and strength, a robust knowledgebased model for accurate concrete strength predictions is still lacking. As an alternative to physical or chemical-based models, machine learning (ML) methods offer a new solution to this problem. Although ML can handle the complex, non-linear, non-additive...conference paper 2021

Li, Z. (author)Alkali-activated materials (AAMs), as eco-friendly alternatives to Ordinary Portland cement (OPC), have attracted increasing attention of researchers in the past decades. Unlike cement, which requires calcination of limestone, AAMs can be made from industrial by-products, or even wastes, with the use of alkali-activator. The production of AAMs...doctoral thesis 2021

van Hooft, J.A. (author)Weather and climate influence life in many ways; varying climatic conditions can be associated with varying human cultures and on a day-to-day basis, the weather influences our plans and mood. As such, a proper prediction of the weather is of great importance. Ultimately, the weather is fueled by solar irradiation, which changes sharply over the...doctoral thesis 2021

Lei, Jintao (author), Qin, Z. (author), Li, Wuhua (author), Bauer, P. (author), He, Xiangning (author)A shunt active power filter (SAPF) is coupled with load admittance in weak grid conditions, which poses a challenge to stability analysis. In this article, the admittance model of the SAPF is developed, which reveals the coupling mechanism between SAPF and load concisely and accurately. On top of that, the stability region of the system is...journal article 2021

Yadav, S. (author), van der Blij, N.H. (author), Bauer, P. (author)Electrification of ships is one of the hot topics in the marine industry. This is due to the stringent guidelines by the International Maritime Organisation (IMO) for curbing the green house gas emissions from the marine sector. In this paper, the state-space modeling approach is used to model bipolar dc grids on ships. A ferry is used as a...conference paper 2021

't Hart, P.A. (author), Babaie, M. (author), Vladimirescu, A. (author), Sebastiano, F. (author)This work presents a self-heating study of a 40-nm bulk-CMOS technology in the ambient temperature range from 300 K down to 4.2 K. A custom test chip was designed and fabricated for measuring both the temperature rise in the MOSFET channel and in the surrounding silicon substrate, using the gate resistance and silicon diodes as sensors,...journal article 2021

Arkesteijn, L. (author), Blom, A. (author), Labeur, R.J. (author)Recent analysis of equilibrium and quasi-equilibrium channel geometry in engineered (fixed-width) rivers has successfully shown that two temporal scales can be distinguished, with quasi-static (long-term) and dynamic (short-term) components. This distinction is based on the fact that channel slope cannot keep pace with short-term fluctuations...journal article 2021

Zhou, Y. (author), Verkou, M.H. (author), Zeman, M. (author), Ziar, H. (author), Isabella, O. (author)Photovoltaic (PV) technology is the most promising renewable energy source to be integrated on urban building surfaces. Modeling and simulating urban PV systems pose more challenges than the conventional ones installed in open field due to rich urban morphology. Herein, a comprehensive workflow to estimate urban solar PV potential is...journal article 2021

Wu, Di (author), Zhang, Yao (author), Ourak, Mouloud (author), Niu, Kenan (author), Dankelman, J. (author), Vander Poorten, Emmanuel B. (author)Catheters are increasingly being used to tackle problems in the cardiovascular system. However, positioning precision of the catheter tip is negatively affected by hysteresis. To ensure tissue damage due to imprecise positioning is avoided, hysteresis is to be understood and compensated for. This work investigates the feasibility to model...journal article 2021

Patent expiry promotes a price competition between manufacturing companies, and more efficient and cheaper processes are needed to achieve lower production costs. Over the last decade, continuous biomanufacturing has...journal article 2021

(author), Fenicia, Fabrizio (author), Matgen, Patrick (author), Savenije, Hubert (author)Process-based hydrological models seek to represent the dominant hydrological processes in a catchment. However, due to unavoidable incompleteness of knowledge, the construction of “fidelius” process-based models depends largely on expert judgment. We present a systematic approach that treats models as hierarchical assemblages of hypotheses ...journal article 2021

Koning, J.R. (author), van der Hoorn, R. (author)Drones are unmanned flying vehicles, which can be used for a broad spectrum of different applications. One of these applications is the generation of albedo maps. However, it could take some time to map an area. Therefore problems can occur the with respect to its flight range, which typically lies between 20 to 45 km for...bachelor thesis 2020

van der El, Kasper (author), Pool, D.M. (author), van Paassen, M.M. (author), Mulder, Max (author)The 1960s crossover model is widely applied to quantitatively predict a human controller's (HC's) manual control behavior. Unfortunately, the theory captures only compensatory tracking behavior and, as such, a limited range of real-world manual control tasks. This article finalizes recent advances in manual control theory toward more general...journal article 2020
