A new constant pressure pendant-drop penetration surface balance has been developed combining a pendant-drop surface balance, a rapid-subphase-exchange technique, and a fuzzy logic control algorithm. Beside the determination of insoluble monolayer compression-expansion isotherms, it allows performance of noninvasive kinetic studies of the adsorption of surfactants added to the new subphase onto...

The degree of difficulty in crushing an ore depends on the composition itself. Due to different types and compositions ores, mechanism ores during process is also different. In order quantitatively analyze impact characteristics mineral components this paper takes pure quartz, pyrrhotite, pyrite as research objects uses universal drop weight test equipment standard methods developed by JK Miner...

Active buffer management can improve the performance of Transmission Control Protocol/Internet Protocol-based networks. Random early detection (RED), an active queue management scheme, has been proposed by the Internet Engineering Task Force for next-generation Internet routers. RED uses a number of parameters, such as buffer thresholds, a packet drop probability and a weight parameter. RED suf...

In this paper the pendant drop method to measure interfacial tension between molten polymers is reviewed. A typical pendant drop apparatus is presented. The algorithms used to infer interfacial tension from the geometrical profile of the pendant drop are described in details, in particular a new routine to evaluate correctly the value of the radius at the apex of the drop, necessary to the calc...

Background: Many research give scatterlly distributed relationship between obesity and the medial longitudinal arch of foot. Among those studies, only two studies have stratified the samples in to underweight, normal weight, overweight and obese groups in the recent past, to explore the relationship of BMI to arch of the foot on the basis of gender variation. Yet these studies contradicted each...
