“…Speed of the train was measured using a pulse generator mounted on a wheel axle. The acceleration signals, measured with sampling frequency of 400 Hz, were filtered using a low‐pass filter to eliminate possible distortion before digitalization 13 . A block in the digitized signal of more than 5 s is converted to the frequency domain using the Fourier transform.…”

“…The International Union of Railways (UIC) and the European Committee for Standardization (CEN), with the ISO, also established standards for the ride comfort of railway vehicles based on ISO 2631. Unlike the methods proposed by ISO 2631 or Sterling, UIC 513R, CEN ENV 12299, and ISO 10056 use statistical methods of evaluation 10–13 Figure 1. compares procedures to evaluate ride comfort using both nonstatistical and statistical methods.…”

The use of robots in healthcare has gained significant attention in recent years. In particular, delivery robots have shown promise in improving efficiency and safety in healthcare facilities, especially in isolation ward settings. This review paper presents the design and development of an IoT-based intelligent delivery robot for isolation wards. The robot is equipped with a variety of sensors and communication devices, enabling it to navigate through the hospital environment and deliver medical supplies and equipment to isolated patients. The system is designed to be remotely controlled and monitored through a web-based interface, providing real-time information on the robot's location, status, and the delivery process. The paper discusses the technical details of the robot's design, including its hardware and software components, as well as the challenges and opportunities of implementing such a system in a healthcare environment. The results of initial tests and evaluations of the robot's performance are also presented, highlighting its potential to improve the efficiency and safety of healthcare delivery in isolation ward settings. Overall, this paper demonstrates the potential of IoT-enabled delivery robots as a valuable tool for healthcare providers, especially in the context of pandemic outbreaks and other public health emergencies.
