71Linear least squares — is an important computational problem, that arises primarily in applications when it is desired to fit a linear mathematical model to measurements obtained from experiments. The goals of linear least squares are to extract predictions from the… …
72Automatic differentiation — In mathematics and computer algebra, automatic differentiation, or AD, sometimes alternatively called algorithmic differentiation, is a method to numerically evaluate the derivative of a function specified by a computer program. Two classical… …
73International Scale of River Difficulty — Class III rapid at Canolfan Tryweryn, Wales. The International Scale of River Difficulty is a standardized scale used to rate the safety of a stretch of river, or a single (sometimes whitewater) rapid. The grade reflects the technical difficulty… …
74Orthogonal coordinates — In mathematics, orthogonal coordinates are defined as a set of d coordinates q = (q1, q2, ..., qd) in which the coordinate surfaces all meet at right angles (note: superscripts are indices, not exponents). A coordinate surface for a particular… …

77Ilfracombe Branch Line — The Ilfracombe Branch of the London South Western Railway (LSWR), ran between Barnstaple and Ilfracombe in North Devon. The branch opened as a single track line in 1874, but was sufficiently popular that it needed to be upgraded to double track… …
78Notation for differentiation — In differential calculus, there is no single uniform notation for differentiation. Instead, several different notations for the derivative of a function or variable have been proposed by different mathematicians. The usefulness of each notation… …
79Electro-gyration — The electrogyration effect is the spatial dispersion phenomenon, that consists in the change of optical activity (gyration) of crystals by a constant or time varying electric field. Being a spatial dispersion effect, the induced optical activity… …
