Wang, R. (author)The random graph is a mathematical model simulating common daily cases, such as ranking and social networks. Generally, the connection between different users in the network is established through preference, and this phenomenon leads to a power-law behaviour of the degree sequence of the random graph. Other than studying this feature, the...master thesis 2020

Belet, Tom (author)Background: While new prosthetic hands are developed to increase functionality and allow more complex movements, prosthetic wrists are researched less. Although there are wrists available, primarily featuring 1 degree of freedom (DoF), only a few prototype 3 DoF wrists are currently known. These 3 DoF wrists usually have sufficient range of...master thesis 2020

Zhang, Y. (author), Yang, Zhengxian (author), Ye, G. (author)Conceptual analysis is performed to examine the effects of pore features on the water continuity in unsaturated porous systems. The roles of pore features in relative chloride diffusion coefficient (D<sub>rc</sub>) of mortar specimens at various degrees of water saturation (S<sub>w</sub>) were studied based on mercury intrusion porosimetry...journal article 2020

Gupta, D.K. (author), van Keulen, A. (author), Langelaar, M. (author)Multiresolution topology optimization (MTO) methods involve decoupling of the design and analysis discretizations, such that a high‐resolution design can be obtained at relatively low analysis costs. Recent studies have shown that the MTO method can be approximately 3 and 30 times faster than the traditional topology optimization method for 2D...journal article 2020

Yin, F. (author), Grewe, V. (author), Gierens, K. (author)iation is responsible for approximately 5% of global warming and is expected to increase substantially in the future. In the face of the continuing expansion of air traffic, mitigation of the aviation’s climate impact becomes challenging, but imperative. Among various mitigation options, hybrid electric aircraft (HEA) has drawn intensive...abstract 2020

Zhang, Y. (author), Ye, G. (author), Yang, Zhengxian (author)Concrete is rarely saturated. Reliable durability design of marine concrete structures requires a solid understanding of the long-term chloride transport in unsaturated concretes. This paper presents a critical analysis of the time-dependent chloride diffusion coefficient in unsaturated cementitious materials exposed to marine environment....journal article 2020

Rahmati, Zahra (author), Behzadipour, Saeed (author), Schouten, A.C. (author), Taghizadeh, Ghorban (author), Firoozbakhsh, Keikhosrow (author)BACKGROUND: Balance training improves postural control in Parkinson's disease (PD). However, a systematic approach for the development of individualized, optimal training programs is still lacking, as the learning dynamics of the postural control in PD, over a training program, are poorly understood. OBJECTIVES: We investigated the learning...journal article 2020

Odijk, Maik (author)This research focuses on the structural behaviour of an elastic supported reinforced concrete slab. Over the years, there is a tendency to realise industrial floors with large joint-spacings. The downside of a slab on grade with a large joint-spacing is that the risk of (uncontrolled) cracking due to a shrinkage load is higher, which often...master thesis 2019

Schaap, Paulus (author)Vibration energy harvesting is the solution for powering on-road sensor measurements. Various techniques to harvest the most energy from a certain application are found in literature. An electromagnetic energy harvester was found to be the best option for transport applications. <br/>In this work, the potential benefits of a coupled oscillator...master thesis 2019

van Strien, Max (author)In 2022, ESA plans to launch the JUICE (JUpiter ICy moons Explorer) mission which will spend at least three years making detailed observations of Jupiter and three of its largest moons, Ganymede, Callisto and Europa. These moons are currently a hot topic within the science community as their interiors might include oceans consisting of liquid...master thesis 2019

Zhang, Y. (author), Ye, G. (author)An analytical model for predicting the relative chloride diffusion coefficient in cementitious materials at different degrees of water saturation is presented in this paper. The model is developed based on the Nernst-Einstein equation and conductivity of cementitious electrolyte, as well as on moisture distribution in the pore structure. Good...journal article 2019

Although balance training improves mobility and postural stability, lack of quantitative studies on the neurophysiological mechanisms of balance training in PD impedes the development of patient-specific therapies. We evaluated the effects of...journal article 2019

Zhang, Y. (author)Chloride-induced reinforcement corrosion, caused by chloride diffusion in the unsaturated concrete cover, is a major durability problem of concrete structures. Current concepts for concrete mixture design and for service life prediction are generally based on the understanding of the chloride diffusion coefficient of saturated concrete. This...doctoral thesis 2018

van Kempen, Liza (author)When a grounding incident occurs, the officer of the watch is usually unable to assess the severity of the damage. Most ships do have damage response procedures in place. In case of military ships these are well developed, where a well-trained crew, in the form of damage parties, is available to respond adequately. For non-navy ships, this is...master thesis 2018

Zuiderveen Borgesius, Freek (author)To limit global warming to 2 degrees Celsius in 2100, the European power sector needs to transform. Renewable energy capacity is required to reach this ambition, together with transmission and storage capacity to maintain grid stability. Carbon capture and storage could potentially decrease the required renewable energy capacity, while...master thesis 2017
