Stabbers of line segments in the plane

چکیده
The problem of computing a representation of the stabbing lines of a set S of segments in the plane was solved by Edelsbrunner et al. We provide efficient algorithms for the following problems: computing the stabbing wedges for S, finding a stabbing wedge for a set of parallel segments with equal length, and computing other stabbers for S such as a double-wedge and a zigzag. The time and space complexities of the algorithms depend on the number of combinatorially different extreme lines, critical lines, and the number of different slopes that appear in S.

Lower Bounds for Line Stabbing
We present an (n log n) xed order algebraic decision tree lower bound for determining the existence of a line stabber for a family of n line segments in the plane. We give the same lower bound for determining the existence of a line stabber for n translates of a circle in the plane. In proving this lower bound, we show that this problem is equivalent to determining if the width of a set of poin...
متن کاملStabbing Segments with Rectilinear Objects
Given a set S of n line segments in the plane, we say that a region R ⊆ R is a stabber for S ifR contains exactly one endpoint of each segment of S. In this paper we provide optimal or near-optimal algorithms for reporting all combinatorially different stabbers for several shapes of stabbers. Specifically, we consider the case in which the stabber can be described as the intersection of axis-pa...
متن کاملLINE-SEGMENTS CRITICAL SLIP SURFACE IN EARTH SLOPES USING AN OPTIMIZATION METHOD
In this paper the factor of safety (FS) and critical line-segments slip surface obtained by the Alternating Variable Local Gradient (AVLG) optimization method was presented as a new topic in 2D. Results revealed that the percentage of reduction in the FS obtained by switching from a circular shape to line segments was higher with the AVLG method than other methods. The 2D-AVLG optimization meth...
متن کاملStabbing Simplices of Point Sets with k-flats
Let S be a set of n points in Rd in general position. A set H of k-flats is called an mk-stabber of S if the relative interior of any m-simplex with vertices in S is intersected by at least one element of H. In this paper we give lower and upper bounds on the size of minimum mk-stabbers of point sets in Rd and in general position. We study mainly mk-stabbers in the plane and in R3.
متن کاملParallelism of the Occlusal Plane with the Ala-tragus Line in Various Posterior References in Dentate Patients
Background and purpose: Occlusal plane in edentulous patients is lost and needs to be reconstructed. The most common method for reconstructing occlusal plane is to make it parallel to the ala-tragus line. There are disagreements about the posterior reference of ala-tragus line. The aim of this study was to determine the best posterior reference of ala-tragus line (superior, middle and anterior ...
