Aragno, Aris (author)This research attempts to develop a space in the city that, outside of the dynamics of consumption, but not denying the dialogue with the city, seeks to intertwine with its overlaps, by defining the public space of dialogue and representation. On the morbidity of performance and expectation, we might say that the contemporary Utopian intent,...master thesis 2024

Li, Meng (author), Shen, Yanzhe (author), Ye, Guixin (author), He, Jialing (author), Zheng, Xin (author), Zhang, Zijian (author), Zhu, Liehuang (author), Conti, M. (author)Digital forensics is crucial to fight crimes around the world. Decentralized Digital Forensics (DDF) promotes it to another level by channeling the power of blockchain into digital investigations. In this work, we focus on the privacy and security of DDF. Our motivations arise from (1) how to track an anonymous- and-malicious data user who...journal article 2024

de Rouw, Lieke (author)INTRODUCTION Surgical counting of instruments forms a crucial part of safety procedures in the operating room (OR). This process has remained primitive without technological support. The manual count process is time-consuming and places heavy cognitive demands on nurses. Current technological approaches fail to detect the exact and detailed...master thesis 2023

(author), Westerweel, J. (author), Suijker, W. (author), van Wijk, R. (author)The principal aim of the work presented here is to investigate and demonstrate that a forward tilted rowing blade would result in a more efficient and effective motion of the blade through the water that would result in a higher boat speed when an equal input power is provided. A 1:5 scaled rowing boat is used to determine the performance of...journal article 2023

de Boer, Pim (author)This work describes the benefits of exploiting cold hydrogen in a 2 MW liquid hydrogen-electric powertrain. Hydrogen is stored in a liquid state in the aircraft at its boiling point of 20 K (at 1 bar). Fuel cells require an input temperature of at least zero degrees Celsius to operate. The heating process can either be done by drawing current...master thesis 2022

Shaikh, Raiyan (author)Emerging PV technologies like Perovskite has lead to the development of Perovskite/Silicon (Pvk/c-Si) tandem device (Multi-junction device) and has now gained a lot of momentum and attention due to the fact that the tandem device can reach a Shockley-Quisser limit of about 44.1% efficiency. But to speed up its development, a lot of emphasis is...master thesis 2022

Beekman, Elwin (author)Background: With around 70 supermarkets, Hoogvliet is one of the smaller supermarkets in the Netherlands. During the past years, more companies have become aware of the importance of efficient reversed logistics (Senthil et al., 2018). By optimizing this return flow, the return hall of supermarkets plays an important role. With the expected...master thesis 2022

Rahimi, Serveh (author), Shooshtari, M. (author)Here we investigated a novel layer-based optimization technique to improve the performance of a CZTSe solar cell. By using this technique, the optical behavior and electrical properties of the proposed solar cell improved significantly as a result of the changes in the layer specifications and the layer materials. The structure of the cell...journal article 2022

Wang, Haochuan (author), Feng, Pan (author), Geng, Zifan (author), Liu, Qi (author)The deterioration of organic coatings on concrete is closely linked to the efficiency in the protection process of reinforced structures. In the present work, polyurea resin and epoxy resin, which are widely used engineering coatings, were selected to measure and compare the performance under artificial aging. Fourier Transform infrared...conference paper 2021

Shekhar, A. (author)Energy transition will inevitably lead to greater electrification. For example, it is anticipated that electrical energy demand will rise by at least 2-3 times by 2050 with increasing share of electric vehicles and heat pumps. This will translate to significant increase in power demand on the existing medium voltage distribution grid, resulting...doctoral thesis 2020
