Low-Frequency Pulse Width Modulation Control Methods of Ultrasonic Motor
Because of the serious non-linearity and coupling among state variables caused by the complex energy conversion process in ultrasonic motor, the motion control strategy of ultrasonic motor still need to be studied in detail to obtain better performance. As a kind of special control method, the low-frequency PWM control strategy can make the on-line optimum control easier, and may be an effectiv...
متن کاملOf NBOs and kHz QPOs: a low-frequency modulation in resonant oscillations of relativistic accretion disks
The origin of quasi periodic modulations of flux in the kilohertz range (kHz QPOs), observed in lowmass X-ray binaries, is usually assumed to be physically distinct from that of the “normal branch oscillations” (NBOs) in the Z-sources. We show that a low-frequency modulation of the kHz QPOs is a natural consequence of the non-linear relativistic resonance suggested previously to explain the pro...
متن کاملModulation of Rat 50-kHz Ultrasonic Vocalizations by Glucocorticoid Signaling: Possible Relevance to Reward and Motivation
Background Rats emit 50-kHz ultrasonic vocalizations (USVs) to communicate positive emotional states, and these USVs are increasingly being investigated in preclinical studies on reward and motivation. Although it is the activation of dopamine receptors that initiates the emission of 50-kHz USVs, non-dopaminergic mechanisms may modulate calling in the 50 kHz frequency band. To further elucidate...
متن کاملEnvironmental and Pharmacological Modulation of Amphetamine-Induced 50-kHz Ultrasonic Vocalizations in Rats
Rats emit high-frequency 50-kHz ultrasonic vocalizations (USV) in appetitive situations like social interactions. Drugs of abuse are probably the most potent non-social elicitors of 50-kHz USV, possibly reflecting their euphorigenic properties. Psychostimulants induce the strongest elevation in 50-kHz USV emission, particularly amphetamine (AMPH), either when applied systemically or locally int...
متن کاملLow frequency ultrasonic debridement: a clinical experience
Low Frequency Ultrasonic Debridement (LFUD) provided by the Sonoca 185 is a new method of debriding wounds that is less traumatic, less painful and can achieve faster healing rates. It is bactericidal and enables many debridement treatments to be undertaken by a podiatrist or wound consultant in their smaller clinical setting. Due to the many properties of LFUD the clinical indications for use ...
