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
Angelo (Measure for Measure) the relationship between justice and mercy. There is much debate about what Shakespeare intended this character to portray. Critics disagree about whether Angelo is a good man who has fallen because of power and sexual temptation or a malicious man from the start. Regardless, he is the personification of justice in the play. When juxtaposed against Isabella (mercy), Angelo represents adherence to the law and punishment for sin, though he does not always adhere to the strict justice he enforces. Once Angelo meets Isabella he is forced to consider himself in a different light and acknowledge his shortcomings. "Measure for
