The finding of an effective BAC < 100 nT and vanishing of the ICR effect for EMF amplitudes exceeding some multiples of that value by some laboratories [ 34] nonetheless could indicate a relatively narrow and sharply defined plane, in which Larmor orbits lie.
The insertion of the alar cartilage into the maxilla was taken as a fixed point and all measurements were performed in a defined axial plane at the level of the maxillary sinus natural ostium.
The clustered points of curvature maxima define planes that can partition a clump of nuclei into individual nucleus.
A defined vertical and horizontal plane were used as reference planes to measure the angles [ 3]; this approach has some limitations: The measurement was performed on standard a.p. radiographs, thus only in a two dimensional system compared to the three-dimensional CT scans used in the present study.
This algorithm relies on spinning an image plane around a defined axis, e.g. the tree stem, collecting the number of LiDAR returns or mean values of returns attributes per pixel as respective values.
A line and a point define a plane.
(iii) For each face f ⊂ ∂ P, all points on F (f ) (also on boundaries and vertices) possess a well defined tangent plane (the limit of the tangent planes, when we go to the vertex, is unique).
It would also in this context be desirable to have a supportive device, e.g. a guiding belt, to take ultrasound images in a precisely defined transversal plane.
Complete coronal correction with complete axial derotation of the vertebrae (C + D correction): First, a "reference plane" defined as the plane including three points, one at the central notch of the lamina and two at the center of the upper and lower endplates on the posterior vertebral wall, was determined for each vertebra from T1 to L5.
The longitudinal axis immediately defines a transverse axis for division and may help to specify a well defined mid-plane.
The horizontal plane (Frankfort plane) was defined as a plane passing through the right porion (R Po), right orbitale (R Or), and left orbitale (L Or).
