Discrete Representation of Straight Lines [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 1984
If a continuous straight line segment is digitized on a regular grid, obviously a loss of information occurs. As a result, the discrete representation obtained (e.g., a chaincode string) can be coded more conveniently than the continuous line segment, but measurements of properties (such as line length) performed on the representation have an intrinsic

Method for TDOA localisation in over-the-horizon environments

open access: yesThe Journal of Engineering, 2019
Here, the authors propose a new over-the-horizon time-difference-of-arrival localisation model based on the ground-wave and simultaneously put forward a modified semi-definite programming algorithm, which is called Ground-wave semi-definite programming ...

Influence of Line Strategy Between Two Turns on Performance in Giant Slalom

open access: yesFrontiers in Sports and Active Living, 2020
In alpine ski racing, different line choices can drastically affect turn or sectional performance. The straight-line transition between two turns is the main phase where skiers can gain speed in a race, open their trajectory, or reduce their path length.

Wavy Wilson Line and AdS/CFT [PDF]

open access: yes, 2004
Wilson loops which are small deviations from straight, infinite lines, called wavy lines, are considered in the context of the AdS/CFT correspondence. A single wavy line and the connected correlation function of a straight and wavy line are considered ...

On the number of limit cycles in discontinuous piecewise linear differential systems with two pieces separated by a straight line [PDF]

open access: yes, 2014
In this paper we study the maximum number $N$ of limit cycles that can exhibit a planar piecewise linear differential system formed by two pieces separated by a straight line.

Pencils of circles with a straight line and circle as the basic elements

open access: yesДифференциальная геометрия многообразий фигур, 2019
Pencils of circles with are a straight line and a circle as the basic ele­ments are investigated. Three cases of arrangement of a basic straight line and a circle are considered: when the straight line does not intersect a circle, when the straight line ...
