3.?Modeling Pazopanib HCl of BP Neural Network3.1. Basic PrincipleFor a certain aircraft, the flow field around the wing surface depends on the free stream air speed V��, the angle of attack �� and the angle of sideslip �� [8,9,14�C17]. Therefore it is reasonable to detect these flight parameters by measuring the flow field around the wing surface. The flow field information around the wing contains two main components: the flow speed and the wall shear stress. Although, the both information is useful for inferring the flight parameters, we paid more attention to the flow speed in this study considering the low Prandtl number of about 0.7~0.8 for air, which is the ratio of velocity boundary layer to thermal bounda
Electrostatic comb-drive actuators, which feature easy design, fabrication Inhibitors,Modulators,Libraries and implementation, are an important type of actuators.
They have been used in various application fields, such as optical communication [1], Inhibitors,Modulators,Libraries biomedical engineering [2], wireless communication [3] and nanotechnology [4]. A longer traveling distance and a larger force output are two major concerns in developing comb-drive actuators. In the last two plus decades, many research efforts were devoted to improve these two major performance factors. These efforts can be grouped into four main directions: optimizing the finger shape [5], modifying the spring shape [6], modifying the configuration of finger overlaps [7] and creating new actuation methods [8].Recently, besides the abovementioned directions, some low stiffness materials, such as polydimethylsiloxane (PDMS) and SU-8, were used to construct the springs of comb-drive actuators to obtain larger displacements [9,10].
Although the expected advantage of using low stiffness materials (usually nonconductive) is achieved, the comb electrodes Inhibitors,Modulators,Libraries of the rotor are inevitably isolated. An extra process of metal deposition is required to make the rotor’s finger electrodes electrically connected with outside circuits once again. During operations, the thin metal layers likely have the risk of delamination. The drawback of the bilayer springs makes the heterogeneous comb-drive actuators unreliable. A suitable method should be developed to cancel the drawback.To eliminate the drawback, a capacitively-coupled-power driven comb-drive actuator (see Figure 1), whose rotor requires no electrical interconnection, was proposed in this article.
In the following sections, the concept and design of the actuator will be explained and analyzed first. Then, the tests for the fabricated actuators will be described, and the results will be discussed. Finally, the conclusions will be made.Figure Inhibitors,Modulators,Libraries 1.Schematics of the comb-drive actuator with the actuation mechanism of GSK-3 capacitively-coupling-power supply.
