A head-related transfer function (HRTF), also known as anatomical transfer function (ATF), [citation needed] is a response that characterizes how an ear receives a sound from a point in space. As sound strikes the listener, the size and shape of the head, ears, ear canal, density of the head, size and shape of nasal and oral cavities, all transform the sound and affect how it is …

The optical transfer function (OTF) of an optical system such as a camera, microscope, human eye, or projector specifies how different spatial frequencies are captured or transmitted. It is used by optical engineers to describe how the optics project light from the object or scene onto a photographic film, detector array, retina, screen, or simply the next item in the optical …

Transfer function in mathematics; Transfer (group theory), a type of homomorphism; Transfer principle, in mathematics; Other sciences. Transfer (computing), movement of data between memory media; Transfer (patent), transfer of intellectual property rights; Call transfer, in telephony; Electron transfer, in chemistry; Heat transfer, in thermal ...

In engineering, a transfer function (also known as system function or network function) of a system, sub-system, or component is a mathematical function that theoretically models the system's output for each possible input. They are widely used in electronics and control systems.In some simple cases, this function is a two-dimensional graph of an independent …

A sigmoid function is a mathematical function having a characteristic "S"-shaped curve or sigmoid curve.. A common example of a sigmoid function is the logistic function shown in the first figure and defined by the formula: = + = + = ().Other standard sigmoid functions are given in the Examples section.In some fields, most notably in the context of artificial neural networks, …

The transfer function. The transfer function is given by the poles in the left half plane of the gain function, and has the same zeroes but these zeroes are single rather than double zeroes. The group delay. Gain and group delay of a fifth-order type II Chebyshev filter with ε = 0.1. The gain and the group delay for a fifth-order type II ...

Atom transfer radical polymerization (ATRP) is an example of a reversible-deactivation radical polymerization.Like its counterpart, ATRA, or atom transfer radical addition, ATRP is a means of forming a carbon-carbon bond with a transition metal catalyst.Polymerization from this method is called atom transfer radical addition polymerization (ATRAP).As the name implies, the atom …

The law holds well for forced air and pumped liquid cooling, where the fluid velocity does not rise with increasing temperature difference. Newton's law is most closely obeyed in purely conduction-type cooling. However, the heat transfer coefficient is a function of the temperature difference in natural convective (buoyancy driven) heat transfer.

The softmax function, also known as softargmax: 184 or normalized exponential function,: 198 converts a vector of K real numbers into a probability distribution of K possible outcomes. It is a generalization of the logistic function to multiple dimensions, and used in multinomial logistic regression.The softmax function is often used as the last activation function of a neural …

The data transfer rate of a drive (also called throughput) covers both the internal rate (moving data between the disk surface and the controller on the drive) and the external rate (moving data between the controller on the drive and the host system).The measurable data transfer rate will be the lower (slower) of the two rates. The sustained data transfer rate or sustained …
