Learning Robust Output Control Barrier Functions From Safe Expert Demonstrations

IEEE Open Journal of Control Systems
This paper addresses learning safe output feedback control laws from partial observations of expert demonstrations. We assume that a model of the system dynamics and a state estimator are available along with corresponding error bounds, e.g., estimated ...

Safety-Guaranteed Course Control of Air Cushion Vehicle with Dynamic Safe Space Constraint

Journal of Control Science and Engineering, 2018
This paper develops a safety-guaranteed course controller for air cushion vehicle (ACV). As the safety criterion, the unique safety limit of ACV including turn rate (TR) and sideslip angle (SA) changes with the speed when ACV is turning.

Re‐Awakening Public Attention to the Silent Pandemic of Cancer Among Older Adults in Low‐ and Middle‐Income Countries

Aging and Cancer, EarlyView.
ABSTRACT As global populations age, cancer is increasingly becoming a leading cause of morbidity and mortality among older adults, particularly in low‐ and middle‐income countries (LMICs). Despite accounting for the majority of new cancer cases and deaths, older individuals remain underrepresented in cancer research, clinical guidelines, and health ...

Error culture and its impact on rework: An exploration of norms and practices in a transport mega-project

Developments in the Built Environment, 2022
Rework has been and continues to be a problem during the construction of transport mega-projects. This article examines the error culture of an alliance that forms part of a transport mega-project to determine its effectiveness in mitigating rework.

Network Localization of Fatigue in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Fatigue is among the most common symptoms and one of the main factors determining the quality of life in multiple sclerosis (MS). However, the neurobiological mechanisms underlying fatigue are not fully understood. Here we studied lesion locations and their connections in individuals with MS, aiming to identify brain networks ...
