Shear flow themselves. In a shearing flow, adjacent layers of fluid move parallel to each other with different speeds. Viscous fluids resist this shearing motion. For a Newtonian fluid, the stress exerted by the fluid in resistance to the shear is proportional to the strain rate or shear rate. A simple example of a shear flow is Couette flow, in which a fluid is trapped between two large parallel plates, and one plate is moved with some relative velocity to the other. Here, the strain rate is simply the relative velocity divided by the distance between the plates. Shear flows in fluids
Universal Metric to Flow Universal Metric to Flow Universal Metric to Flow (UMF) technology enhances the ability to utilize Cisco NetFlow data for rapid traffic analysis. Developed by network performance management company, "SevOne", in early 2010 and announced at Cisco Live in Las Vegas in July that year, the UMF technology was designed to automate the performance troubleshooting workflow, a major problem within the industry. Universal Metric to Flow enables network operations to graph key network performance metrics from SNMP or network latency derived from IP SLA, observe a spike, highlight it, and drill down into the network traffic, providing immediate visibility into the
