A numerical method is used to evaluate the influence of propeller parameters on the aerodynamic performance of shrouded coaxial dual rotors in hover.Compared with the open-rotor configuration, the shrouded rotors reduce the tip vortex, resulting in a higher thrust and figure of merit (FoM).The varying inflow distribution over the inlet lip Music Bo
It is significant for diagnosing the early faults of wind turbine planetary gearboxes.However, the weak transient feature generated by the early gear failure is often submerged in other vibration signals and noise, thus this paper discusses a new automatic sparse representation method for detecting weak transients.An improved Morlet wavelet which s
The Internet of Things (IoT) plays a major role in healthcare, and high-end encryption schemes are needed to ensure data integrity and privacy in this industry.The security procedures and methodologies in the healthcare industry must be improved to combat various security breaches brought on by the IoT.The methodologies such as Advanced Encryption
In this paper Connector Tubing we present findings of an exploratory study, included in a wider investigation which intends to promote meaningful learning of physics concepts, based on experimental work and supported by metacognition tools.The aim of this research was to recognize promoting learning situations in Physics lab.Interviews and question
