By distinguishing long and short TCP flows, we address in this paper the problem of efficiently computing the characteristics of long flows. Instead of using time consuming off-line flow classification procedures, we investigate how flow characteristics could directly be inferred from traffic measurements by means of digital signal processing techniques. The proposed approach consists of classi...

Among the all parameters affecting the performance of a downhole de-oiling hydrocyclone, the investigation of internal flow field deserves more attempts especially in the petroleum industry. In this study, the effects of inlet flow rate, inlet oil volume fraction, and oil droplet diameter on the separation efficiency and pressure drop ratio have been investigated along the hydrocyclone body. Al...

The rapidly growing field of biotechnology has created a critical need for simple, fast andhigh-throughput processes for the separation and purification of biomolecules from biologicalmatrices. In recent years, several bioseparation techniques have been proposed as advancedalternatives to the classical separation methods. These modern processes emphasize ultrahighselective and sensitive analysi...

An algebraic principle for blind source separation is presented in this paper. This separation principle identi"es a (smaller) set of equations whose solutions can blindly extract non-Gaussian signals. The concept of `Mth-order uncorrelatednessa is introduced and it is proven that for Mth-order uncorrelated source signals, signals with nonzero kth-order cumulant (2(k)M) can always be extracted ...

conclusions trichotillomania may also be seen in preschool-aged children and may be associated with separation anxiety disorder. improper and late treatment can be associated with a worsening of the disorder. case presentation a 4.5-year-old girl without any psychiatric disorders in the family. she was cared for by her mother, and the child had a history of separation anxiety. after detection o...

the emergence and unprecedented growth of joint stock companies is undoubtedly one of the most significant economic developments.one of the outcomes of this development is the separation of ownership and control of the companies. such separation make it possible for the managers of the companies to make dicisions to serve their interes at the expense of the companies shareholders .this conflict...

In a generic group decision scenario, the decision makers review alternatives and then provide their own individual ranking. The aggregate ranking problem is to obtain a ranking that is fair and representative of the individual rankings. We argue here that using cardinal pairwise comparisons provides several advantages over scorewise models. The aggregate group ranking problem is then formalize...
