The high-frequency strategy was first made popular by Renaissance Technologies [27] who use both HFT and quantitative aspects in their trading. Many high-frequency firms are market makers and provide liquidity to the market which lowers volatility and helps narrow bid–offer spreads, making trading and investing cheaper for other market ...
Ordinary people have better reading performance using high-frequency (20–60 kHz) electronic ballasts than magnetic ballasts, [10] although the effect was small except at high contrast ratio. The flicker of fluorescent lamps, even with magnetic ballasts, is so rapid that it is unlikely to present a hazard to individuals with epilepsy . [ 11 ]
The list was first published in a journal article in 1936 [1] and then published in his book Problems in Reading in 1948. [2] Dolch compiled the list based on children's books of his era, which is why nouns such as "kitty" and "Santa Claus" appear on the list instead of more current high-frequency words.
Frequency illusion is common in the linguistic field. Zwicky, who coined the term frequency illusion, is a linguist himself. He gave the example of how linguists "working on innovative uses of 'all,' especially the quotative use," believed their friends used the quotative "all" in conversation frequently.
Skimming is a process of speed reading that involves visually searching the sentences of a page for clues to the main idea or when reading an essay, it can mean reading the beginning and ending for summary information, then optionally the first sentence of each paragraph to quickly determine whether to seek still more detail, as determined by the questions or purpose of the reading.
This may be accomplished by time stretching and then resampling back to the original length. Alternatively, the frequency of the sinusoids in a sinusoidal model may be altered directly, and the signal reconstructed at the appropriate time scale. Transposing can be called frequency scaling or pitch shifting, depending on perspective.
Radio over fiber (RoF) or RF over fiber (RFoF) refers to a technology whereby light is modulated by a radio frequency signal and transmitted over an optical fiber link. Main technical advantages of using fiber optical links are lower transmission losses and reduced sensitivity to noise and electromagnetic interference compared to all-electrical signal transmission.
