The article reveals the researches on the characteristics, manifestations and defects of vocal technique with high impedance, which is the main criterion for evaluating the professionalism of each singer-performer of academic manner. The necessity and timeliness of research of the aforementioned problem is proved. The essence of the concepts of “vocal technique”, “defects of vocal sound”, “impedance”,...
In this article, a novel coherent amplitude demodulation based on time-varying force function of second-order oscillator circuit and injection locking Phenomenon is proposed. The compactness of demodulation circuit is obtained because amplitude demodulation mechanism is inherent in one oscillator circuit. With injection locking property, frequency and phase of the oscillator is identical to that of...
Differentiation of normal human bladder cell (SVHUC) between two different-grade bladder cancer cell lines (TSGH8301, grade II and TCCSUP, grade IV) was successful developed based on a dielectrophoresis (DEP) microchip with microcavity array and multilayer electrodes. Single cell could be firstly trapped in the microcavity by negative DEP force between top and middle electrodes without overlapping...
This paper describes a simplified parallelization of the near-field interaction in the multilevel fast multipole algorithms (MLFMA) based on a data decomposition strategy with an improved load balancing and the data locality. It shows good performance on distributed memory computers using the message passing interface (MPI).
The single-sided stator configurations of the linear induction motor are analyzed, and the traction force and the normal force equations are derived using two different methods. The first way we solve the for the two-dimensional field distribution in the air gap and in the secondary, the mutual reactance and secondary impedance are derived account for the longitudinal end effect factor and other electromagnetic...
