Definition of "skew"

When making this joint it is important to see that the eccentric or crank is at dead-centre; if it is at the end or limit of its stroke, the rubber is skewed the full length of same; if it is at the centre, the skewing, which is the cause of wear, is halved.

Thus asynchronous torques cannot be avoided but can be reduced by proper choice of coil span and by skewing the stator or rotor slots.

Skewing an object, as we mention at the start of this section, involves distorting the angles of the object. For example, you can create a parallelogram by skewing a square, or you can create shadow effects with skewed text (which we show you later in this chapter).

The easiest way to skew objects is to use the Free Transform tool. [...] Use the left box to skew horizontally. To skew clockwise, click the current value and then either type a value between 1 and 89 or drag up. To skew counterclockwise, click the current value and then either type a value between -1 and -89 or drag down. Then press Enter or Return.

The horses capered. One tore its reins from her hands, burning a trail across her palms. She clung to the other as it pulled against the restraint. Frantically, Brienne moved to its side, pitching the reins over the beast's head, and jammed her foot into the stirrup. The horse skewed, drawing her along on one foot.

Ocular tilt reaction [...]—the triad of head tilt in roll, skew deviation of the eyes, and cyclorotation of the eyes towards the head tilt—may indicate a lesion induced deviation of the primary position of the vertical VOR [vestibulo-ocular reflex] in either peripheral otolithic or central vestibular brain stem disorders.

Through the given point there are two lines one of which is parallel to one of the given skew lines, while the other is parallel to the other of the given skew lines. These two "parallels" determine a plane, and the only plane, that is parallel to both the given skew lines.

The angle of skew, or obliquity, is the angle which the axis of the archway, A A, makes with a perpendicular to the face of the arch, B C A B. The span of the archway, "on the square," as it is called (that is, the perpendicular distance between the abutments), is less than the span on the skew, or parallel to the face of the arch, in the ratio of the cosine of the obliquity to unity. It is the span on the skew which is equal to that of the corresponding symmetrical arch.

It is apparent that by shifting the position of the hitching link the angle of skew may be increased or diminished as the conditions require. When dragging immediately over ruts or down the center of the road after the sides have been dragged, it is usually preferable to have the hitching link at the center of the chain and to run the drag without skew.

One application for which an optical filter can play an important role is that of a wideband connection with low time skew. [...] One signal, the clock, needs to be distributed to all parts of a digital circuit to synchronize its action. The necessarily long path results in the danger of the clock signal arriving at the wrong time (clock skew), limiting the maximum frequency at which the circuit may be clocked.

1989, Ivan Andonovic, Deepak Uttamchandani, editors, Principles of Modern Optical Systems, volume 1, Norwood, Mass.: Artech House, page 501

Until recently, there has been a great reluctance to alter the clock network and attempt a nonzero-skew solution. However, recently, an increasing number of designers have been willing to utilize skews for performance enhancement.

Skewness (skew) is the degree to which a distribution's shape departs from symmetry [...]. The greater the departure, the greater the skew. Symmetric distributions have no skew. For instance, the normal distribution is symmetric and is thus not a skewed distribution.

Skew is the contour, or the unevenness, in a distribution, the dent in the bell curve. A negative skew suggests that the left half of the normal distribution (the left side of the mean) is twisted in such a way that the prospect of achieving negative returns is superior to that of achieving large positive returns. [...] When dealing with skew, traders strive to resolve how frequently in the trading time horizon they will obtain negative returns rather than positive returns. A skew demonstrates the relationship between the movement of an underlying asset and its volatility.

Gable Copings or Skews are of various forms of section, the most common varieties being the parallel sided, Fig. 654; the weathered, or feather-edged, Fig. 655; and the saddle-backed, Fig. 656. [...] The skews at the eaves terminate in what is termed a club-skew or skew-corbel. This admits of an infinite variety of forms, according to the style of the building, but the object is the same in all—namely, to afford a support and abutment to the skew.

The architecture of the steadings given in Plates I. to IX. is of the simplest description—plain rubble-work, with broached ashlar corners, rebates, lintels, and skews, and the roofs extending in stretches, and terminating in gables, without points to be affected by the weather. [...] A somewhat more ornamental style is given in Plate XV. of the farm-steading at Coleshill, in Berkshire, the corners and rebates being in raised work, and the skews of the gables ridged and pinnacled.

Skew and crest: this phrase, which occurs in the specifications for the repairs at the Tower of London, (23 H. VIII.,) plainly describes the common coping of a wall which consists of a sloping or skew surface surmounted by a roll moulding by way of crest; sometimes there are two skews, separated by a set-off.
