1. Which colour is associated with trust? Blue has “an air of reliability”, because of its constant presence in our lives. 2. Why do people notice red first? Red has a longer wavelength than most colours, which means it “stand...

Radio-frequency unbalanced M–Z interferometer for wavelength interrogation of fiber Bragg grating sensors 来自 掌桥科研 喜欢 0 阅读量: 217 作者:J Zhou,L Xia,R Cheng,Y Wen,J Rohollahnejad 摘要: The optical unbalanced Mach–Zehnder interferometer (UMZI) has attracted significant interests for ...
Studies have indicated that red "raises blood pressure", and claim that it stands out from other colours thanks to its long wavelength. Hemingway says it appears to be "coming towards you", and so is useful for emergency and alarm signs, and also to for conveying "urgency" in general. Th...
to CNN's (its nearest competitor) estimated 200 million. Its radio service is in the short wavelength, which makes it available to many regions of the world. It also broadcasts news - by radio or over the Internet - in some 30 languages.Cable News Network, commonly referred to...

The wavelength was 21 centimetres. That's the wavelength of light, of radio waves emitted from hydrogen atoms. So the whole sky glows at that wavelength. And, back in the 1950s, radio astronomers speculated that if an alien civilisation wanted to communicate with us, then they might well ...
Several auxiliary functions such as analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and general-purpose inputs/outputs (GPIOs) for power amplifier (PA) and radio frequency (RF) front-end control are also integrated. The fully integrated phase-locked loops (PLLs) ...
From the "worse than we thought" department comes this new climate model, but at least they acknowledge the pause. The next few years could be "anomalously warm", according to a new study. Researchers have developed a mathematical model to predict how av
Simultaneous dual-wavelength observations by the KAO of a recent Chiron occultation provide a measure of the relative extinction efficiencies of particles near Chiron. This observation and Mie scattering theory allow us to constrain the size of grains causing the extinction of the starlight near Chiron...
