Line, английский
- The basic unit of a frame or field containing the charge, which is proportional to the light falling at various points on the scanning line.
- L
- A report on how well a stranger plays
- Линия
- The correct nautical term for the majority of the cordage or "ropes" used on a vessel. a line will always have a more specific name, such as mizzen topsail halyard, that specifies its use.
- Линь, вер?вка, шнур
- Линь, линия
- The general appellation of a number of small ropes in a ship, as buntlines, clue-lines, bowlines, &c. also, the term in common parlance for the equator. also, in the army, distinguishes the regular numbered regiments of cavalry and infantry from the artillery and guards, to whom exceptional functions are assigned. in fortification, it means a trench, approaches, &c. in a geometrical sense, it signifies length without breadth; and in military parlance, it is drawing up a front of soldiers.—concluding line. a small rope, which is hitched to the middle of every step of a stern-ladder.—deep-sea line. a long line, marked at every five fathoms with small strands of line, knotted, and used with the deep-sea lead. the first 20 fathoms are marked as follows: 2 and 3 fathoms with black leather; 5 with white bunting; 7 with red; 10 with leather and a hole in it. then 13, 15, and 17 repeat the previous marks of 3, 5, and 7. two knots indicate 20, three knots 30, four knots 40 fathoms, and so on, with an additional knot for every ten. meanwhile a single knot indicates the intermediate fives. besides this system some pilots prefer their own marks, as in the hooghly, where they always measure the line for themselves. the term “deep-sea line” must not now be confined to the use of the lead for the ordinary purposes of safe navigation; deep-sea soundings for scientific purposes are recorded in thousands of fathoms, in which case the line is sometimes made of silk, the object being to obtain the largest amount of strength with a small weight.—fishing-lines. particular kinds of lines, generally used for fishing snood, mackerel, whiting, cod, albacore, &c.—hand-line. a line about 20 fathoms long, marked like the first 20 fathoms of the deep-sea line. it is made fast to a hand-lead of from 7 to 14 lbs., and used to determine the depth of water in going in or out of a harbour, river, channel, &c.— hauling-line. any rope let down out of a top, &c., to haul up some light body by hand.—knave-line. a rope fastened to the cross-trees, under the main or fore top, whence it comes down by the ties to the ram-head, and there it is rove through a piece of wood about 2 feet long, and so is brought to the ship`s side, and there hauled up taut to the rails.—life-line. a rope occasionally extended in several situations for persons to lay hold of, to prevent their falling.—mar-line. a particular kind of small line, composed of two strands very little twisted; there is both tarred and white mar-line. that supplied for the gunner and for bending light sails is untarred.—navel-line. a rope depending from the heads of the main and fore masts, and passed round to the bight of the truss to keep it up, whilst the yard is being swayed up, or when the truss, in bracing sharp up, is overhauled to the full.—spilling-lines. ropes fixed occasionally to the square sails, particularly the main and fore courses in bad weather, for reefing or furling them more conveniently; they are rove through blocks upon the yard, whence leading round the sail they are fastened abaft the yard, so that the sail is very closely confined.—white-line. that which has not been tarred, in contradistinction to tarred line.
- [1] is generally defined as being cordage of less than 1-inch (2.5 cm) in circumference. [2] in the usn it refers to rope that has been unspooled and cut for use. [3] one of the dimensions of a convoy, see column. see also braided line.
- Lines. 1. wire and/or fiber ropes and cables. 2. a given direction, bearing, or course.
- To cover the inner surface of. a lined tunnel is a tunnel where
- Гидролиния, магистраль
- A description of the location and grade of a tunnel.
- A continuous mark on a surface, which imparts motion and contour to a design.

Relationship, английский
- Отношение: соотношение; связь; взаимоотношение; взаимосвязь

Regression, английский
- Statistical technique used to evaluate relationships among variables (22).
- Регрессия
- 1. a stage where symptoms of a disease are disappearing and the person is getting better 2. (in psychiatry) the process of returning to a mental state which existed when the person was younger
- Regression commonly refers to the process of developing an empirical (data-driven) model to predict and/or explain one or more attributes in a database or set of data. it is most frequently associated with the simple linear model (y=mx+b) taught in most introductory statistics courses; the same ideas have been extended in many directions, including classification problems. when the emphasis is on hypothesis testing and simple models, the regression output is typically a few parameters that provide a direct linkage from the input variables to the predicted variables (or classification). in other situations the emphasis is on explaining as much of the variability in the output variables as is "reasonable" from the input variables. in this case, there are a number of "advanced" techniques, such as smoothing splines, decision trees, neural nets, and so forth, for which there are many "free" parameters. the meaning of any one of these parameters can be obscure. many data mining techniques are, at their core, variations on well-known regression techniques. see also: classification, clustering, decision trees, neural nets.
- The reappearance of a previously fixed problem.
- The statistical process of predicting one or more continuous variables, such as profit or loss, based on other attributes in the dataset.
- A mathematical technique used to explain and/or predict. the general form is y = a + bx + u, where y is the variable that we are trying to predict; x is the variable that we are using to predict y, a is the intercept; b is the slope, and u is the regression residual. the a and b are chosen in a way to minimize the squared sum of the residuals. the ability to fit or explain is measured by the r-square.
- A seaward retreat of a shoreline, generally expressed as a seaward
