Roeplal, R.N. (author), Pang, Y. (author), Schott, D.L. (author)Bed permeability is a crucial factor in blast furnace performance which depends on the material distribution achieved through charging. Since a homogeneous bed of pellet and sinter is recommended, it is crucial to understand whether segregation of the pellet-sinter mixture occurs during charging. The Discrete Element Method is useful in this...journal article 2024

(author), De Ras, Kevin (author), Vlugt, T.J.H. (author)The use of reactive working fluids in thermodynamic cycles is currently being considered as an alternative to inert working fluids, because of the preliminarily attested higher energy-efficiency potential. The current needs to simulate their use in thermodynamic cycles, which may operate in liquid, vapour or vapour-liquid state, are an...journal article 2024

Krempus, D. (author), Bahamonde, Sebastian (author), van der Stelt, T.P. (author), Klink, Wolfgang (author), Colonna, Piero (author), de Servi, C.M. (author)The use of mixtures as working fluids of organic Rankine cycle (ORC) waste heat recovery (WHR) power plants has been proposed in the past to improve the matching between the temperature profile of the hot and the cold streams of condensers and evaporators, thus to possibly increase the energy conversion efficiency of the system. The goal of...journal article 2024

Zhang, Tianming (author), Yan, Gaowei (author), Li, Rong (author), Xiao, Shuyi (author), Pang, Y. (author)The industrially collected process data usually exhibit non-Gaussian and multi-mode characteristics. Due to sensor failures, irregular disturbances, and transmission problems, there are unavoidable outliers that make the data exhibit heavy-tailed characteristics. To this end, a variational auto-encoder regression method based on the mixture...journal article 2024

Zhu, P. (author), Wang, Zhen (author), Okumura, Manabu (author), Yang, J. (author)Textbook question answering is challenging as it aims to automatically answer various questions on textbook lessons with long text and complex diagrams, requiring reasoning across modalities. In this work, we propose MRHF, a novel framework that incorporates dense passage re-ranking and the mixture-of-experts architecture for TQA. MRHF...conference paper 2024

Mohammadkarimi, M. (author), Leus, G.J.T. (author), Rajan, R.T. (author)A new method for joint ranging and Phase Offset (PO) estimation of multiple drones/aircrafts is proposed in this paper. The proposed method employs the superimposed uncoordinated Automatic Dependent Surveillance-Broadcast (ADS-B) packets broadcasted by drones/aircrafts for joint range and PO estimation. It jointly estimates range and PO prior...journal article 2024

Noorman, Julie (author)In Kigali, Rwanda, urbanization and increased affluence will increase the amount of waste. Currently, there is no sustainable disposal of the waste, as unsorted waste is deposited in an unsanitary landfill, which is beginning to fill up. The Rwandan government aims to create a circular economy and tries to address waste management, but few...master thesis 2023
