Ni, Xinrui (author), Hu, Wei (author), Fan, Q. (author), Cui, Yibing (author), Qi, Chongkai (author)Artificial bee colony (ABC) is a prominent algorithm that offers great exploration capabilities among various meta-heuristic algorithms. However, its monotonous and one-dimensional search strategy limits its searching performance in the solving process. Thus, to address this issue, a Q-learning based multi-strategy integrated ABC algorithm ...journal article 2024

Cui, Z. (author), Zhang, Y. (author), Hu, D. (author), Vollebregt, S. (author), Fan, J. (author), Fan, X. (author), Zhang, Kouchi (author)Understanding the atomic diffusion features in metallic material is significant to explain the diffusion-controlled physical processes. In this paper, using electromigration experiments and molecular dynamic (MD) simulations, we investigate the effects of grain size and temperature on the self-diffusion of polycrystalline aluminium (Al). The...journal article 2022

Hu, D. (author), Gu, Tijian (author), Cui, Z. (author), Vollebregt, S. (author), Fan, Xuejun (author), Zhang, Kouchi (author), Fan, J. (author)In high power electronics packaging, sintered silver nanoparticle joints suffer from thermal-humidity- electrical-chemical joint driven corrosion in extreme environments. In this paper, we conducted aging tests on sintered silver nanoparticles under high-temperature, high-humidity, and high-sulphur conditions. The results show that: (1) the...journal article 2021

Hu, D. (author), Cui, Z. (author), Fan, J. (author), Fan, X. (author), Zhang, Kouchi (author)A molecular dynamics (MD) simulation was performed on the coalescence kinetics and mechanical behavior of the pressure-assisted Cu nanoparticles (NPs) sintering at low temperature. To investigate the effects of sintering pressure and temperature on the coalescence of the nanoparticles, sintering simulations of two halve Cu NPs were conducted at...journal article 2020
