Deep Reinforcement Learning (DRL) recently emerged as a possibility to control complex systems without the need to model them mathematically. In contrast to classical controllers, DRL alleviates the need for constant parameter tuning, tedious design

We present a novel framework for controlling non-steady situations in chemical plants to address the behavioural gaps between the simulator for constructing the reinforcement learning-based controller and the real plant considered for deploying the f

In cylindrical traverse grinding, a slender workpiece is bent by the normal grinding force due to its low stiffness. Consequently, a form error is generated by the elastic deformation of the workpiece during the grinding process. To prevent such defo

In cylindrical grinding, the size accuracy of a workpiece decreases due to the thermal deformation of the ground workpiece. To improve the size accuracy, it is necessary to consider the thermal deformation of the workpiece during grinding process. In

Daily dose distributions for adaptive radiotherapy (ART) using helical tomotherapy (HT) are calculated using megavoltage computed tomography (MVCT). Generally, the MVCT number is converted to mass density (MD) using an MD calibration table (MVCT-MD t

In the cylindrical grinding process, the residual grinding allowance is left owing to the rubbing of the abrasive grains and the elastic deformation of the grinding system caused by the large normal grinding force. Therefore, a sizing gauge is genera

Efficient strengthening systems for tunnel lining concrete (TLC) have not been sufficiently discussed while various systems are available for other structures. The study aims at development of a strengthening system applicable for TLC. In particular,
