Gatidis, C. (author)Precipitation is a profoundly important meteorological process and a crucial component of the water cycle. Thus, the continuous and reliable monitoring of precipitation at global scale is fundamental for scientific sectors such as numerical weather prediction and hydrology. However, accurately estimating precipitation, its type and intensity at...doctoral thesis 2024

Cruciata, Giorgio (author), Cruciata, Luca (author), Lo Presti, Liliana (author), van Gemert, J.C. (author), La Cascia, Marco (author)This paper proposes a new method to improve the training efficiency of deep convolutional neural networks. During training, the method evaluates scores to measure how much each layer’s parameters change and whether the layer will continue learning or not. Based on these scores, the network is scaled down such that the number of parameters to be...journal article 2024

Haayen, Bas (author)Balanced armature receivers are electroacoustic transducers that are mostly integrated in hearing aids or pro audio products. The balanced armature receiver is a key component for hearing aids as it converts the processed electrical signal into sound waves. Failure of the balanced armature receiver are problematic for the end user. The receivers...master thesis 2023

Wu, Pansy (author)Traffic congestion is a challenge that frequently emerges due to changes in the roadways such as tunnels and sags, causing capacity reduction. The capacity drop phenomenon exacerbates traffic congestion, due to decreased queue discharge rates. Among the strategies employed for traffic management, Variable Speed Limit (VSL) control is a common...master thesis 2023

Luo, Maoyi (author), Wang, Hang (author), Zheng, Xiaohui (author), Wüthrich, D. (author), Bai, Ruidi (author), Liu, Shanjun (author)In high dam construction projects in China, stilling basin design with an abrupt bottom drop is sometimes introduced to reduce the bottom velocity and pressure loads by generating A-type hydraulic jumps. Although the stilling basin design is not new, A-type hydraulic jumps have not been studied taking into account the air entrainment and...journal article 2023

Toa, X. (author), Shen, Yunwei (author), Wang, Bo (author), Infante Ferreira, C.A. (author)High concentration NH<sub>3</sub>/H<sub>2</sub>O is suitable for Kalina cycles used for the recovery of low grade heat. Plate heat exchangers (PHEs) are compact and reduce the charge of working fluid. This paper investigates the condensation of NH<sub>3</sub>/H<sub>2</sub>O with NH<sub>3</sub> mass concentrations of 80%-96%. The vapor and...journal article 2023

Gao, Y. (author), Liu, X. (author), Ren, S. (author), Li, Yuanyuan (author), Zhang, Yuqing (author)Surface energy is a key material property and can work as a crucial parameter in various mechanical models to predict the moisture sensitivity and fatigue damage of asphalt mixtures. The calculated surface energy values of the aggregate minerals strongly depend on their surface roughness. Therefore, it is very relevant for accurate...journal article 2023

van Kuijk, J.J.A. (author)Fatigue crack growth in metals has been studied intensively for more than half a century. This research field has been closely connected to the engineering industry throughout history. It is therefore no surprise that the main focus has mostly been on developing better prediction models rather than on understanding the phenomenon of fatigue...doctoral thesis 2022

van den Brule, Yannick (author)The knowledge of the raindrop size distribution is key for characterizing precipitation. It is however still a challenge to retrieve it with radars. Several polarimetric and spectral techniques are proposed for cm-wavelength radars (weather radars). What about the mm-wavelength radars (cloud radars), which have a better spatial and time...master thesis 2022

(author), Eser, Bekir Engin (author), Kara, Selin (author)Since its discovery in 2017, the fatty acid decarboxylase (FAP) photoenzyme has been the focus of extensive research, given its ability to convert fatty acids into alka(e)nes using merely visible blue light. Unfortunately, there are still some drawbacks that limit the applicability of this biocatalyst, such as poor solubility of the...journal article 2022

Maričić, Marko (author)Ride-pooling is a key concept for the future of human mobility and vital in the roll-out of Mobility-as-a-Service (MaaS). Pooling allows individuals to travel at a reduced fare (when comparing to a private alternative) due to the reduction in operating costs as the usage of the vehicles is increased; essentially, the main intentions of pooling...master thesis 2021
