In this paper, experiments of crude oil demulsification using ultrasound, chemical demulsifier, and the combined method ultrasound respectively, at different temperatures (40°C, 60°C, 70°C) are carried out. The photos water droplet distribution in oil, taken with microscopic imaging system, before after above methods 70°C given. Research results show that demulsifier has best effect, followed by demulsifier. Ultrasound without least effect. Furthermore, impact ultrasonic power, treatment...
Purpose: Footwork speed is closely linked to explosive strength, and both percentage- (PBRT) velocity-based resistance training (VBRT) are popular methods for developing muscle strength. This study aimed compare the effects of PBRT VBRT on lower limb power footwork movement in elite university badminton players over a 6-week period. Methods: A total 20 (12 males, 8 females) from Tongji University were randomly divided into (n = 10) groups 10). The group trained with loads determined by...
<ns3:p>Stroke disrupts brain structure, leading to long-term disabilities despite improved survival rates. Patients often face cognitive, sensory, and motor deficits, with incomplete spontaneous recovery. Early intervention is crucial, as significant improvements happen within three months, while cognitive enhancements may take months years. Recently, the periosteal traction (PD) technique has gained in treating chronic lower limb ischemia, speculation that it effectively promotes...
In this paper, a computational method for numerical solution of class integro-differential equations with weakly singular kernel fractional order which is based on Cos and Sin (CAS) wavelets block pulse functions introduced. Approximation the arbitrary integral also obtained. The are transformed into system algebraic by using operational matrix integration CAS wavelets. error analysis given. Finally, results some examples support validity applicability approach.
In this paper, a cancelling system for linear and three nonlinear frequency modulated signals is proposed. According to the RCS (Radar Cross Section) characteristic of target, amplitude phase modulation are made acquire signal having same as echo pulse but with opposite phase. This cancels radar signal. The basic theory active cancellation stealth introduced. Based on two kinds target fluctuation models (Swerling I Swerling III), formulas detection probability given. influence amplitude,...
