Ammonium sulfate is one of the subsidiary components in the stealth liposome structure. The ratio of ammonium ion bound to liposome sphere to ammonium ions outside the liposome plays an important role in drug delivery formulation; accordingly, in order to quantify the ammonium ion in the liposome structure, a rapid and sensitive method was validated using a conductivity detector. Through this m...

this paper presents a new control structure to reduce torque ripple in switched reluctance motor. although srm possesses many advantages in motor structure, it suers from large torque ripple that causes some problems such as vibration and acoustic noise. in this paper another control loop is added and torque ripple is de ned as an objective function. by using fuzzy sliding mode strategy, the dc...

ABSTRACT This paper provides a report of a research effort to transform architectural and scenographic surfaces into sound sources and use them in artistic creation. Structure-borne sound drivers are employed to induce sound into the solid surfaces, making them vibrate and emit sound. The sound waves can be perceived both via the aural (airborne diffusion) as well as the tactile (structure-born...

In order to detect knock in spark ignition engines, usually structure-borne sound signals measured by acceleration sensors mounted on the engine housing are analyzed. Earlier investigations have shown that using linear, time variant filtered structure-borne sound signals as approximated pressure signal instead improves knock detection significantly. But this method is computationally too expens...

The mining chute is an important equipment in the process of coal transportation and coal screening preparation. During the working process, the mining chute will generate a lot of vibration and noise because of constantly friction and impact of gangue and coal blocks. In order to reduce the vibration and noise during the operation of the chute, a new type of foam aluminum laminated structure i...

Anthropogenic noise emission in the marine environment is a key issue nowadays and has drawn the attention of regulatory bodies in various nations. In particular, the noise generated during the installation of foundation piles for the offshore wind industry is considered to be harmful for aquatic species. A reliable prediction of the underwater noise during the installation of a foundation pile...

Space-borne gravitational wave detection imposes a demanding requirement on the sensitivity of laser interferometer. Among all disturbances that affect measurement accuracy interferometer, temperature fluctuations contribute significantly. In this paper, structure model and interference path design Taiji-1 interferometer have been used to conduct preliminary simulation analysis fluctuation nois...
