PURPOSE Results in several studies have suggested that the visual evoked potential (VEP) amplitude can vary with stimulus duration. The purpose of this study was to determine whether acuity estimates obtained by extrapolation of the sweep VEP are altered by this adaptation effect. METHODS Sweep VEP data were obtained from 16 healthy observers under binocular viewing conditions. Data were acqu...

We consider the problem of nding a corridor (a separating strip) between two polygons, whose intersection with a third (convex) polygon is of maximum area. The application in mind is the interpolation in simple branching cases, where the sought volume branches from one contour in one slice into two polygons in another parallel slice. We present a linear-time plane-sweep algorithm which computes...

Hardwood sawmills traditionally saw logs in a manner that either orients sawlines parallel to the log central axis (straight sawing) or the log surface (allowing for taper). Sweep is characterized as uniform curvature along the entire length of a log. For logs with sweep, lumber yield losses from straight and taper sawing increase with increasing levels of sweep. Curve sawing logs with sweep wi...

This paper presents three selection techniques (called Rubber-lingsweep, Line-string and Coupling-with-pressure) to enhance multi-target acquisition in GUIs and to overcome the drawback of the standard rubber-band box technique, i.e., the limitation of not being able to select an irregular layout of targets. Rubber-line-sweep utilizes a rubber-band line to select targets by “sweeping” them. Lin...

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...

The objective of this paper is to examine the application of the Half-Sweep Geometric Mean (HSGM) method by using the half-sweep approximation equation based on quadrature formula to solve linear integral equations of Fredholm type. The formulation and implementation of the Full-Sweep Geometric Mean (FSGM) and HalfSweep Geometric Mean (HSGM) methods are also presented. Some numerical tests were...

OBJECTIVE To determine if sweep visual evoked potential (VEP) acuity is predictive of recognition acuity in children with albinism. METHODS A retrospective review was performed in children with albinism who underwent sweep VEP testing from 1992 to 2003. All patients had a complete ophthalmologic examination with either binocular or monocular sweep VEP testing and at least 5 years of follow-up...

The separation and on-line concentrations of lysergic acid diethylamide (LSD), iso-lysergic acid diethylamide (iso-LSD) and lysergic acid N,N-methylpropylamide (LAMPA) in human urine were investigated by capillary electrophoresis-fluorescence spectroscopy using sodium dodecyl sulfate (SDS) as an anionic surfactant. A number of parameters such as buffer pH, SDS concentration, Brij-30 concentrati...
