Owls have developed serrations, comb-like structures, along the leading edge of their wings.Serrations were investigated from a morphological and a mechanical point of view, but were not yet quantitatively compared for different species.Such a comparative investigation of serrations from species of different sizes and activity patterns may provide

The automatic generation of Chinese enterprise abbreviations is a task that extracts enterprise abbreviations to represent the enterprise full name.Traditional methods do not divide abbreviations in detail, which leads to a poor generation effect of irregular Chinese enterprise abbreviations generation, and the best selection method of candidate ab
In this research, an active antenna operated at the second harmonic frequency is investigated, and is implemented using microstrip antenna material.The antenna consists of a FET oscillator which plays as a fundamental frequency oscillator and a frequency multiplier, and a patch antenna resonated at the second harmonic frequency as the radiator.A ma
An extended nonlinear disturbance observer (ENDOB)-based fuzzy sliding mode control approach is proposed for single-input and single-output systems with matched and mismatched uncertainties/disturbances, and it is extended to the general wavertree and london cosmopolitan candle $n$ th order systems.By integrating the mismatched disturbance estimati
