The droplet size distribution in the column is usually represented as the average volume to surface area, known as the Sauter mean drop diameter. It is a key variable in the extraction column design. A study of the drop size distribution and Sauter-mean drop diameter for a liquid-liquid extraction column has been presented for a range of operating conditions and three different liquid-liquid sy...

a two-dimensional cfd model of a planar solid oxide fuel cell (sofc) has been developed.this model can predict the performance of sofc at various operating and design conditions.the effect of knudsen diffusion is accounted in the porous electrode (backing) and reaction zonelayers. the mathematical model solves conservation of electrons and ions and conservation ofspecies. the model is formulate...

In this investigation, the performance of a tower for absorption of sulphur dioxide gas into calcium carbonate solution has been studied. The trays had no downcomer and the tower itself was a scaled down pilot from industrial equipment. The industrial scale tower was used for clean up of 110000 m3/hr gas using 40 m3/hr alkaline solution. The study was composed of two parts. In the first section...

Using data from the first seven waves of the Health and Retirement Study (1992 to 2004), the authors examined the extent to which joint retirement expectations were realized, the role of couple-level agreement in facilitating joint retirement, whether husbands' or wives' expectations were more likely to be realized in cases of disagreement, and factors associated with the realization of expecta...

OBJECTIVE To test the reproducibility of tests and criteria for generalized joint hypermobility (GJH) and benign joint hypermobility syndrome (BJHS). METHODS A standardized protocol for clinical reproducibility studies was followed using a three-phase study (with a training, an overall agreement and a test phase). An overall agreement of at least 0.80 was required to proceed to the test phase...

We address the problem of analyzing multiple related opinions in a text. For instance, in a restaurant review such opinions may include food, ambience and service. We formulate this task as a multiple aspect ranking problem, where the goal is to produce a set of numerical scores, one for each aspect. We present an algorithm that jointly learns ranking models for individual aspects by modeling t...

Abstract. Several robotic system applications require manipulators to carry heavy payloads while operating from moving vehicles. These manipulators are mounted on moving/compliant bases, introducing additional degrees of freedom that are not actuated, increasing the complexity of the dynamic modeling and control. In this paper, a control strategy to improve the performance of mobile robotic man...
