Anemometer turbines usually requires a refresh rate of wind speed measurements of 3 Hz, easily achieved by sonic anemometers. Three-dimensional sonic anemometers are widely used to measure gas emissions and ecosystem fluxes using the eddy covariance method when used with fast-response infrared gas analyzers or laser-based analyzers. Two-dimensional wind sensors are of two types: Acoustic resonance anemometers are a more recent variant of sonic anemometer. The technology was invented by Dr Savvas Kapartis and patented in 2000. Whereas conventional sonic anemometers rely on time of flight measurement, acoustic resonance sensors use resonating acoustic (ultrasonic) waves within a small purpose-built cavity in
What Does the K Stand For? feel less like real people than excuses to weave in a few good dad jokes". Overall, Elan found, "What lifts the show are the elements of diaspora life weaved throughout, as when Aunty Princess visits from Nigeria and accuses Virginia [Stephen's mother] of cultural betrayal ('You have adopted too many fine and fancy British ways'). Stephen defends the family by suggesting she should 'go back home', prompting him to reflect that he has turned into his own racist enemy. It's unexpectedly thoughtful stuff, suggesting the third series may be even better." What Does the K Stand For? What Does the
