A hybrid aerial vehicle (HAV), featured combination of a quadrotor system and a fixed-wing system, is one of the most promising configurations having both a vertical take-off and landing (VTOL) capability and high cruise performance. In this paper, a HAV has been designed and prototyped to analyze the performance of the HAV. The specifications of the HAV are summarized. The aerodynamic coefficients...
The aim of this investigation is to determine if the heterogeneous sonoporation depends on the microbubble size. Using a customized ultrasound exposure and observation setup, we observed sonoporation dynamics at the single-cell level and quantified exogenous molecular uptake levels to evaluate the degree of sonoporation. The non-uniform size distribution of SonoVue microbubbles themselves allowed...
Aimed at the problem that it is easy for buses to roll in the extreme-turn conditions, the paper finished a series of analysis. First, bus turning driving dynamics model was established based on the effect of suspension motion on roll angle. In the extreme-turn conditions Roll stability and critical roll angle threshold were analyzed, and formulas of roll angle prediction and roll angle threshold...
Based on the force analysis of the roll for vehicles under the extreme turning, comparative analysis and simulation verification are carried out for the two kinds of calculation methods of the roll critical safety speed under the situations of whether or not taking account of the effect of suspension in the vehicle roll analysis. From three aspects of "driver operation — vehicle structure parameter...
The near-field acoustic levitation (NFAL) relative to other suspension methods has some unique advantages, such as no special requirements on the electromagnetic properties of the object, with considerable levitation and driving force, and so on. A novel ultrasonic levitation of gyroscope has been developed based on the inverse piezoelectric effect. The ultrasonic vibration is induced by two B04 flexural...
