To estimate the value of pulse wave velocity (PWV) in pediatric cardiovascular disease, prospective studies are needed. Various instruments based on different measurement principles are proposed for ...

There seems to be a discrepancy between measurement of the expansion of the Universe using radiation in the early Universe and using nearby objects. Researchers have now contributed to this debate by ...

First, the design of deep-space open-loop velocity measurement on the basis of China’s DSN (CDSN) is presented. The process of deep-space open-loop velocity measurement contains six steps. First, ...

Abstract: An improved understanding of the interactions between fluid dynamics and thermal non- equilibrium (TNE) effects, which result from strong shocks, is critical in developing improved thermal ...

Archery and target shooting with firearms and air guns are just a few of the many sports and pastimes that involve high-speed projectiles. Try this measurement technique. Archery and target shooting ...

Stream gaging sure was a dapper occupation at the turn of the century! Here’s the various techniques United States Geological Survey hydrologists used to measure current without even dipping a toe ...

Velocity is one of the, or THE, key metric used by most agile teams to size, plan, and ensure that they are on track. For scrum-based teams, it is hard to think how they would operate without it. It’s ...
