Bánsági, Aurél (author)In group recommendation, a key question is how preferences from individuals should be obtained and then aggregated into a group outcome. Collecting individual preferences can be done through implicit or explicit means, but there is insufficient research available on what option is optimal. For comparing different possible aggregation strategies,...master thesis 2021

Ouali, Mouad (author)The Dutch infrastructure counts many bridges, the majority of which are built in concrete. These bridges have been designed and constructed according to safety codes. A lot of these bridges date from the previous century and have been designed conform outdated safety codes. Therefore, the main problem<br/>of these bridges is the uncertainty with...master thesis 2021

Visser, Romée (author)<br/>Elections polls have been known to exist since 1824 [14], to fulfill the objective of what is happening and may happen. In this thesis it is investigated what the performance of election polls is and if the aggregation of polls give a better forecast than the polls themselves. The data is used of Spain during years 2012 until 2017 and The...bachelor thesis 2021

Mylonas, Akis (author)In the Netherlands, yearly 33 Mton new concrete (roughly 15 billion m3) is producewhile 12 Mton concrete waste becomes available. Recycling of the yearly 12 Mton concrete waste results in roughly 7 Mton coarse recycled concrete aggregate (CRCA) and 5 Mton fine recycled concrete aggregates (fRCA). Currently, fRCA is not used in structural...master thesis 2021

Culea, Horia (author)Federated learning is a machine learning technique proposed by Google AI in 2016, as a solution to the GDPR regulations that made the classical Centralized Training, not only unfeasible, but also illegal, in some cases. In spite of its potential, FL has not gained much trust in the community, especially because of its susceptibility to data...bachelor thesis 2021

Verbraeken, Joost (author)Federated learning (FL) is a type of machine learning where devices locally train a model on their private data.<br/>The devices iteratively communicate this model to a central server which combines the models and sends the updated model back to all devices.<br/>Because the data stays on the devices and only the model is transmitted, federated...master thesis 2021

Koster, Martin (author)In practice, many applications like traffic monitoring and smart grids rely on computing functions on privacy-sensitive data. In order to protect privacy-sensitive data and still keep the ability to compute any arbitrary function, multi-functional privacy-preserving data aggregation schemes have been created. These schemes, however, can be...master thesis 2021

Nedeljković, Marija (author), Visser, Jeanette (author), Nijland, Timo G. (author), Valcke, Siska (author), Schlangen, Erik (author)In the Netherlands, beside cement replacement with more green cement types, there is also an urgent need for alternative materials for natural sand in new concrete in order to make it circular. Furthermore, the recyclers have raised questions regarding upscaling and the potential of fine recycled concrete aggregates (fRCA) in structural concrete...conference paper 2021

Dong, H. (author), Yao, X. (author), Burgmann, S. (author), Ye, G. (author)Each year a large amount of construction and demolition waste (CDW) is generated in the European Union. For sustainability development the CDW is recycled and re-used. To promote the use of CDW, recycled aggregates from CDW were incorporated in alkali-activated concrete (AAC), which mainly consisted of secondary materials or industrial by...conference paper 2021

Qiu, Xiujiao (author), Chen, Jiayi (author), Ye, Guang (author), De Schutter, Geert (author)ASR (alkali-silica reaction) is one of the toughest durability problems in engineering. However, the damage induced by ASR is still fairly unpredictable due to the lack of microstructural information of cement-based materials affected by ASR, while the microstructure determines the global performance. In order to fill this gap, a multiscale...conference paper 2021

Zhang, Zhidong (author), Angst, Ueli M. (author)The structure of concrete, in particular the microstructure of the steel-concrete interface (SCI), can significantly affect corrosion of rebars. To support corrosion, oxygen needs to diffuse from the ambient environment to the steel surface. Meanwhile, corrosion products transport through the SCI and precipitate in concrete. Transport properties...conference paper 2021
