The constrained optimal control problem depends on the solution of the complicated Hamilton-Jacobi-Bellman equation (HJBE). In this paper, a data-based off-policy reinforcement learning (RL) method is proposed, which learns the solution of the HJBE and the optimal control policy from real system data. One important feature of the off-policy RL is that its policy evaluation can be realized with dat...
OBJECTIVE: This study aimed to evaluate the effects of ultrasound-guided rectus sheath block in gynaecological surgery with Pfannenstiel incision.
A woman in her 60s was evaluated for anterior chest pain. Computed tomography (CT) revealed a 50 mm mass with irregular contrast enhancement in the an...
BACKGROUND: A brain-machine interface (BMI) should be able to help people with disabilities by replacing their lost motor functions. To replace lost f...
Most robotic applications that contain shape memory alloy (SMA) actuators use the SMA in a linear or spring shape. In contrast, a novel robotic finger...
Tactile sensors suffer from many types of interference and errors like crosstalk, non-linearity, drift or hysteresis, therefore calibration should be ...
The correct classification of individuals is extremely important for the preservation of genetic variability and for maximization of yield in breeding...
INTRODUCTION: Surgical management of duplex renal anomaly (DRA) is complex because of individual anatomic variation, competing priorities of vesicoure...
Comparison of surgical techniques must be critically and objectively evaluated, ideally in the context of prospective trials. Comprehensive surgical t...
