Pulsating jets are very common and sometimes useful in industrial fields, due to some differences in basic characteristics from steady jets.In this research, the authors focus upon the mechanism of the frequency effect on a finite-amplitude pulsating jet.Experiments are conducted at a Reynolds number of 5,000, Strouhal numbers of 0.13, 0.20 and 0.2
This paper investigates the formation tracking control problem of a group of underactuated surface vessels (USVs) in the presence Singing Bowls of model uncertainties and environmental disturbances.Additional constraints, such as collision avoidance, heterogeneous limited communication range and input saturation are also considered.A modified barri
As a measurement, quality of service (QoS) has been commonly taken into account in the traditional vertical handoff schemes for the heterogeneous wireless access networks.However, the QoS is not sufficient to correlate well with the user satisfaction.In this paper, Nakiri quality of experience (QoE) is introduced into the decision mechanism of the
Proportional Integral Derivative (PID) controller is still the most widely used controller in the industry.However, the presence of varying time delay and input constraint cause PID controller performance to deteriorate and produce unsatisfactory operation.This situation becomes worsening if the Power Scooters varying time delay and input constrain
Abstract Aim The White Paper on Crime 2019 Singing Bowls from the Japanese Ministry of Justice reported that the percentage of crimes committed by people with mental disabilities was only 1.0%.In contrast, the findings of a statistical survey of correctional facilities reported that 15.1% of the prisoners were diagnosed with a mental illness.This s
