The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...

When monitoring network traffic, a flow measurement approach can provide the advantage of data reduction in near real-time. RTFM, the IETF’s standard, generalised architecture for measuring traffic flows, and NeTraMet, an open-source implementation of that architecture, are introduced. The results of a NeTraMet usage survey are presented, together with a detailed description of the NeTraMet com...

One of the primary measurements the physician would like to acquire from a patient is that of the concentration of O2 and other nutrients in the cells. Such quantities are normally so difficult to measure that the doctor is forced to accept the second-class measurements of blood flow and changes in blood volume, which usually correlate with concentration of nutrients. If blood flow is difficult...

Though the popular Cisco NetFlow is widely used for flow-level traffic measurement in IPv4 networks, it is not suitable for IPv6 networks because of the fixed flow structure that cannot carry IPv6-related information. Therefore, the IETF IP Flow Information eXport (IPFIX) standard that employs the flexible flow template structure has been recently proposed to support various flow-level traffic ...

In 14 subjects with normal coronary arteries the mean coronary sinus blood flow was 122 25 mI/min (range, 83 to 159 ml/min). The blood flow computed per 100 g of left ventricle was 82 + 16 ml/min, which is in the range of values obtained by nitrous oxide and coincidence counting methods. In 35 patients with arteriographically confirmed coronary artery disease the mean flow was similar (128 + 20...

A new method for the measurement of argon isotope composition in a continuous flow of helium for potassium/argon geochronology is described. Extraction of argon from geological samples in multiple-sample holders was carried out in a chamber by heating with a continuous Nd-YAG laser. The extracted and pre-concentrated argon is passed through a chromatographic capillary column in a flow of helium...
