Sweeps, arrangements and signotopes
Sweeping is an important algorithmic tool in geometry. In the rst part of this paper we deene sweeps of arrangements and use thèSweeping Lemma' to show that Euclidean arrangements of pseudolines can be represented by wiring diagrams and zonotopal tilings. In the second part we introduce a new representation for Euclidean arrangements of pseudolines. This representation records anòrientation' fo...
متن کاملApproximating selective sweeps.
The fixation of advantageous mutations in a population has the effect of reducing variation in the DNA sequence near that mutation. Kaplan et al. (1989) used a three-phase simulation model to study the effect of selective sweeps on genealogies. However, most subsequent work has simplified their approach by assuming that the number of individuals with the advantageous allele follows the logistic...
متن کاملOrthogonal sweeps of vibroseis
Vibroseis is a method that imparts coded seismic energy into the ground. The energy is recorded with geophones and then processed using the known (coded) input signal. The resulting time-domain representation of vibroseis data is an impulsive wavetrain with wavelet properties consistent with the coded input signal convolved with the earth’s reflectivity series. Historically vibratory seismic su...
متن کاملComputing nice sweeps for polyhedra and polygons
The plane sweep technique is one of the best known paradigms for the design of geometric algorithms [2]. Here an imaginary line sweeps over the plane while computing the property of interest at the moment the sweep line passes the required information needed to compute that property. There are also three-dimensional problems that are solved by space sweep, where a plane sweeps the space. This p...
متن کاملTrade Arrangements and Evolving East Asian and Asia Pacific
The paper begins by noting that proposals involving significant developments in the regional tradearchitecture are being developed within regional processes that in some cases are simultaneouslypursuing other dimensions of regional economic integration: monetary and financial cooperation inthe case of ASEAN + 3, and the establishment of a common market in the case of ASEAN. At leastthree of the...
