There may not be an individual belaying pin for each line; since the buntlines are invariably worked together several of them may be secured to the same pin. Some sails, in addition to clewlines and buntlines, have leechlines to pull the edges into the centre when they are stowed (see picture).
The original definition appearing in [2] requires that G = S . The definition presented above is a common generalisation of this. From a computational perspective, the formal definition of a straight-line program has some advantages. Firstly, a sequence of abstract expressions requires less memory than terms over the generating set.
Given a line and any point A on it, we may consider A as decomposing this line into two parts. Each such part is called a ray and the point A is called its initial point. It is also known as half-line (sometimes, a half-axis if it plays a distinct role, e.g., as part of a coordinate axis). It is a one-dimensional half-space. The point A is ...
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
This is the definition that appeared more than 2000 years ago in Euclid's Elements: "The [curved] line [a] is […] the first species of quantity, which has only one dimension, namely length, without any width nor depth, and is nothing else than the flow or run of the point which […] will leave from its imaginary moving some vestige in length ...
By definition, different streamlines at the same instant in a flow do not intersect, because a fluid particle cannot have two different velocities at the same point. Pathlines are allowed to intersect themselves or other pathlines (except the starting and end points of the different pathlines, which need to be distinct).
Aerofoil nomenclature showing chord line Chord line of a turbine aerofoil section. Chords on a swept-wing. In aeronautics, the chord is an imaginary straight line segment joining the leading edge and trailing edge of an aerofoil cross section parallel to the direction of the airflow.
Portion of trotline, showing method of baiting on snoods. A trotline is a heavy fishing line with shorter, baited branch lines commonly referred to as snoods suspending down at intervals using clips or swivels, with a hook at the free end of each snood.
