Flow behaviour and thermal separation mechanism on vortex tubes have been studied numer-ically. Rapid expansion indicated by high-pressure gradient near the inlet exit ports contributes to energy parallel counter flow tubes. It creates a cooling process at core region drives an internal rotational transfer peripheral region, then increases gas temperature periphery along with friction due prese...

Vivas have multiple functions in academia, but their main goal is completing thesis evaluation. At the heart of this evaluation is a series of criticisms and their responsive turns by which participants talk vivas as institution into being (Heritage, 1997). Turn-taking is one of the many ways vivas are talked into being. This study drew upon conversation analysis to look into the turn allocatio...

In this paper, a new approach for blind source separation is presented. This approach is based on minimization of the mutual information of the outputs using a nonparametric “gradient” of mutual information, followed by a projection on the parametric model of the separation structure. It is applicable to different mixing system, linear as well as nonlinear, and the algorithms derived from this ...

In this work, an improved single-column chromatographic (ISCC) separation process is proposed. The term `improved' refers to both conceptual and physical modifications compared to the available single-column processes, including a novel fraction collection scheme and allowing overlapped peaks from adjacent cycles. Also the fraction collection mechanism was modified in order to facilitate online...

In the past, investigations of phase separation in concentrated polymer solutions centered first of all on the crystallization kinetics (1) and morphology (2) of polymer crystals growing from solutions and, secondly, on the equilibrium thermodynamic properties of liquid-liquid phase separation phenomena (3). Papkov and Yefimova (4) have recently given a classification of different types of phas...
