Li, Z. (author), Wyrzykowski, Mateusz (author), Dong, H. (author), Zhang, Shizhe (author), Lura, Pietro (author), Ye, G. (author)Alkali activated slag (AAS) has shown promising potential to replace ordinary Portland cement as a binder material. Synthesized from industrial by-products, AAS can show high strength, thermal resistance and good durability. However, AAS has been reported to exhibit high autogenous shrinkage. Autogenous shrinkage is a critical issue for building...conference paper 2021

Wani, F.M. (author), Shipurkar, U. (author), Dong, J. (author), Polinder, H. (author)Improving availability of tidal turbines has been identified as a key area to lower the levelized cost of energy from tides. One of the approaches suggested to achieve high reliability is to use a flooded permanent magnet (PM) generator. Flooded PM generators are designed to operate with a seawater filled stator-rotor gap in the generator. Using...conference paper 2019

Klop, Casper L. (author), Dong, J. (author), Olsen, Pål Keim (author)The ModHVDC concept is a modular permanent magnet generator which uses insulated stator segments with dedicated power electronic converters to produce HVDC. This could significantly reduce the number of required power conversion steps for HVDC-connected offshore wind parks. However, the concept poses structural challenges to the machine design,...conference paper 2023

Liang, X. (author), Dong, H. (author), Li, Z. (author), van Zijl, Marc Brito (author), Ye, G. (author)This paper investigated the feasibility of using biomass fly ash (BFA) to prepare alkaliactivated slag and fly ash paste. The reference mixture was alkali-activated slag and coal fly ash (CFA) paste with a slag-to-coal fly ash ratio of 50/50. In other mixtures, coal fly ash was replaced at 40% and 100% with BFA, respectively. The results showed...conference paper 2021

(author)In high-power wireless battery charging that uses inductive power transfer, a considerable amount of power losses are located in the transmitter and receiver coils because they carry high resonant currents and typically have a loose coupling between them which increases eddy current losses. Therefore, the nominal operation needs to be chosen...conference paper 2020

Dong, J. (author), Sharifi K., Arman (author), Mohajerin Esfahani, P. (author)In this paper, we propose an approach to detect mode transitions and to isolate active modes in discrete-time, switched affine systems. The proposed approach is in particular constructed for systems in which the controller is oblivious of the switching signal. The diagnosis approach consists of two main parts: construction of a bank of output...conference paper 2021
