| rotational transform | <radiobiology> \iota = 2PI/q) Due to the combination of applied toroidal field and induced poloidal field, the magnetic field lines wind helically around the torus (and on most flux surfaces they fill the surface ergodically). The rotational transform is a measure of this helicity, and is defined as the average angle the field line shifts in the poloidal direction per complete circuit in the toroidal direction. The quantity q = 2\pi / \iota is known as the "safety factor'' because of its role in stability theory. A magnetic field configuration is said to posses rotational transform if the lines of force, after one complete circuit around the configuration (for example, a torus) do not simply close exactly on themselves, but are instead rotated through some angle about the magnetic axies.

| transform | To be changed in form; to be metamorphosed. "His hair transforms to down." (Addison) 1. To change the form of; to change in shape or appearance; to metamorphose; as, a caterpillar is ultimately transformed into a butterfly. "Love may transform me to an oyster." (Shak) 2. To change into another substance; to transmute; as, the alchemists sought to transform lead into gold. 3. To change in nature, disposition, heart, character, or the like; to convert. "Be ye transformed by the renewing of your mind." (Rom. Xii. 2) 4. <mathematics> To change, as an algebraic expression or geometrical figure, into another from without altering its value. Origin: L. Transformare, transformatum; trans across, over + formare to from: cf. F. Transformer. See Form. Source: Websters Dictionary (01 Mar 1998) |
| Fourier transform | Analysis based on the mathematical function first formulated by jean-baptiste-joseph fourier in 1807. The function, known as the fourier transform, describes the sinusoidal pattern of any fluctuating pattern in the physical world in terms of its amplitude and its phase. It has broad applications in biomedicine, e.g., analysis of the X-ray crystallography data pivotal in identifying the double helical nature of DNA and in analysis of other molecules, including viruses, and the modified back-projection algorithm universally used in computerised tomography imaging, etc. (12 Dec 1998) |
