Wu, Yike (author)Background: Kidney failure, also called end-stage renal disease, means the kidney has lost its function to remove waste from the blood. Patients with kidney failure usually need hemodialysis, which uses a machine to replace the function of a healthy kidney, to keep them alive and prolong their lives. In order to begin hemodialysis, it is crucial...master thesis 2023

Xin, Jianbin (author), Wu, Xuwen (author), D'Ariano, Andrea (author), Negenborn, R.R. (author), Zhang, Fangfang (author)Most of the existing path planning methods of automated guided vehicles (AGVs) are static. This paper proposes a new methodology for the path planning of a fleet of AGVs to improve the flexibility, robustness, and scalability of the AGV system. We mathematically describe the transport process as a dynamical system using an ad hoc mixed...journal article 2023

Wu, Jun (author), Miller, Thomas E. (author), Cicirello, A. (author), Mortimer, Beth (author)Often overlooked, vibration transmission through the entire body of an animal is an important factor in understanding vibration sensing in animals. To investigate the role of dynamic properties and vibration transmission through the body, we used a modal test and lumped parameter modelling for a spider. The modal test used laser vibrometry...journal article 2023

Yu, F. (author), Ching, Wai Ki (author), Wu, Chufang (author), Gu, Jia Wen (author)In this paper, we consider optimal pairs trading strategies in terms of static optimality and dynamic optimality under mean–variance criterion. The spread of the entity pairs is assumed to be mean-reverting and follows an Ornstein–Uhlenbeck process. A constrained optimal control problem is considered, and the Lagrange multiplier technique is...journal article 2022
