چکیده

This study demonstrates that the hydrodynamic phenomena taking place inside the capillary limits the frequency range of voltage pulses for stable single event electrospraying SEE , when the meniscus/cone size is defined by the inner diameter of the nozzle. For the analysis of SEE, we used a one-dimensional model describing the displacement and oscillations of the liquid inside the nozzle. The frequency range of voltage pulses for stable SEE is related to the natural oscillation frequency of the fluid column inside the capillary. © 2009 American Institute of Physics. doi:10.1063/1.3269594

Preliminary Design of Spacecraft Attitude Control with Pulse-Width Pulse-Frequency Modulator for Rest-to-Rest Maneuvers

In this paper, the preferred region of design parameters for quasi-normalized equations of single-axis attitude control of rigid spacecraft using pulse-width pulse-frequency modulator (PWPFM) is presented for rest-to-rest maneuvers. Using the quasi-normalized equations for attitude control reduces the system parameters, that is, the moment of inertia, the filter gain, and the maximum torque of ...

Comparison the treatment effects between simultaneous dual frequency and single frequency irradiation of ultrasound in a murine model of breast adenocarcinoma

Introduction: Transient cavitations induced by low frequency irradiation of ultrasound can be used to treat tumors. Previous studies in in-vitro experiments have shown that induced cavitation by dual or multiple frequencies of ultrasound is greater than induced cavitation by single frequency irradiation. In this study, we compared and evaluated the treatment effects of dual frequency irradiatio...

Relativistic Bi-Stability in a Plasma Beatwave Accelerator

Beatwave excitation of plasma waves is analyzed in the regime where relativistic corrections to the plasma frequency are important. It is shown that a long beatwave pulse can excite strong plasma waves in its wake even when the beatwave frequency is detuned from the electron plasma frequency. The wake is caused by the dynamic bi-stability of the nonlinear plasma wave if the beatwave amplitude e...

Evaluating the Effects of Dual Frequency Sonication Parameters on Acoustic Cavitation by Chemical Dosimeter Using Iodide

Background and Aims: Production of acoustic cavitation by sonication has been recently recommended as a targeted treatment. The experimental results from studies indicate that the activity of cavitation generated by bi- or multi-frequency ultrasound irradiation is higher than that caused by single frequency irradiation. In this study, effects dual (1 MHz and 40 kHz) and single frequency soni...
