[Faransky] has created a very impressive Arduino function generator that doesn’t skimp on the features. Capable of generating sine, triangle, and square waves up to 10MHz with its all-digital ...

To eliminate this frustrating problem, [WilkoL] built a useful pulse generator for use in the lab. [WilkoL] notes that historically, the job of generating pulses of varying length and frequency ...

Refers to computerized trading using proprietary algorithms. There are two types high frequency trading. Execution trading is when an order (often a large order) is executed via a computerized ...

These models are grounded on how the exchanges work, whether the algorithm is trading with better informed traders (adverse selection), and the type of information available to market participants at ...

Algorithmic trading (AT) and high-frequency trading (HFT) have come to dominate the trading world, particularly HFT. During 2009-2010, more than 60% of U.S. trading was attributed to HFT.

For water waves and sound waves the unit hertz is usually good enough but radio and TV waves have such a high frequency that the kilohertz (\(kHz\)) or even the megahertz (\(MHz\)) are better units.

The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.
