System Runs Many Processes Concurrently Process: executing program State consists of memory image + register values + program counter Continually switches from one process to another Suspend process when it needs I/O resource or timer event occurs Resume process when I/O available or given scheduling priority Appears to user(s) as if all processes executing simultaneously Even though most syste...

In this work, the characteristics of flow and heat transfer of a fluid containing nano particles of aluminum oxide with the water volume fraction (0.1-0.2-0.3)(V/V) percent of the reports. The overall heat transfer coefficient, heat transfer and the average heat transfer fluid containing nano water - aluminum oxide in a horizontal double pipe counter flow heat exchanger under turbulent flow con...

A gravitationally stable boundary between two polymer solutions in a ternary system can develop into an interphase of structured convectional flow. The transport over this interphase is by counter-current distribution and as a result high-molecular weight material moves by bulk-flow and much more rapidly than low-molecular weight material, which is transported essentially by ordinary diffusion.

We present numerical simulations of the magnetic field generated by the flow of liquid sodium driven by two counter-rotating impellers (VKS experiment). Using a kinematic code in cylindrical geometry, it is shown that different magnetic modes can be generated depending on the flow configuration. While the time averaged axisymmetric mean flow generates an equatorial dipole, our simulations show ...

In this paper, we address issues related to flow correlation attacks and the corresponding countermeasures in mix networks. Mixes have been used in many anonymous communication systems and are supposed to provide countermeasures that can defeat various traffic analysis attacks. In this paper, we focus on a particular class of traffic analysis attack, flow correlation attacks, by which an advers...

The analytical solutions for the temperature variation of two streams in parallel flow, counter flow and cross-flow heat exchangers and related entropy generation due to heat exchange between the streams are presented. The analysis of limiting cases for the relative entropy generation is performed, and corresponding analytical expressions are given. The obtained results may be included in a mor...
