What's the difference between bisector and bivector?
Bisector
Definition:
(n.) One who, or that which, bisects; esp. (Geom.) a straight line which bisects an angle.
Example Sentences:
(1) Speech and noise are both spectrally shaped according to the bisector line of the listener's dynamic-range of hearing, but with the noise in a single octave band (0.25-0.5 or 0.5-1 kHz) increased by 20 dB relative to this line.
(2) The Voronoi polyhedron of a given S-phase cell nucleus is that polyhedron of minimal volume defined by planes all of which are perpendicular bisectors of the vectors extending from the given cell to all other S-phase cells in the tumor.
(3) The results suggest that the dioxygen ligand is strongly tilted, the direction of tilt being close to one of the bisectors of the N-Fe-N bond angles.
(4) For the three-dimensional non-coplanar case, homogeneous target dose distributions are obtained by designing field modifiers which produce a uniform dose distribution on the perpendicular bisector plane for each pair of fields.
(5) Distinctive bisector analysis patterns are positively correlated with each sleep--waking stage.
(6) Speech and noise are shaped by the same amplitude-frequency response; their spectra are varied relative to the bisector of the individual's dynamic range.
(7) All AT-containing polydeoxynucleotides and crab satellite DNA adopt a high humidity a modified B form characterized by the orientation of the bisector of the phosphate group OPO at 64 degrees with respect to the helical axis which is significantly lower than 68-74 degrees observed in DNAs.
(8) This constant is the ratio of absolute dose rate in medium, 1 cm from the source on its transverse bisector, to source strength.
(9) The deviation of the bisector of (formula: see text) of the greater than PO2- group from the normal to the bilayer is less than 45 degrees and the mean orientation of all polar head groups is rather parallel than perpendicular to the plane of the bilayer.
(10) This A form is characterized by the orientation of the bisector of the phosphate OPO group at 34 degrees with respect to the helical axis, which is slightly lower than that of DNA.
(11) Dose is calculated as a function of angle with respect to the transverse seed bisector for distances from the seed center ranging from 0.1 to 7.5 cm.
(12) After a brief review of available data in the literature on the sections for surgical approach to the cervical segment of the thoracic duct, the authors made a comparative analysis, using time-honoured objective criteria on surgery, between the universal transverse cervical section (20 operated patients) for approach to the cervical segment of the thoracic duct and the oblique cervical section which they suggest (28 operated patients) it passes along the bisector of the angle formed between the thoracic pedicle of the sternocleidomastoid muscle and the upper edge of the left clavicle.
(13) The system of loading, which results in observable physiologic response, maintains the compressive load at virtually 90 degrees at the bisector of the disc for all weights and all angles of forward flexion.
(14) A new developed discrimination method--the bisector method--is used for discrimination and classification between the normal and pathological groups.
(15) Although the 1974 version of the EEG bisector analysis is not exactly comparable to visual analysis, in this design it defined significant drug effects on sleep and EEG.
(16) Using electroencephalogram (EEG) bisector analysis, tape recordings of sleep were analyzed for two beta, three alpha, three theta, and two delta EEG patterns, as well as for detections of sleep spindles, K-complexes, eye movements, body movements, average electromyogram (EMG), and calculation of seven sleep-waking stages.
(17) If the screw is introduced, as recommended by Danis, in the bisector of the angle between the perpendicular on the fracture fissure and the perpendicular on the bone axis, one obtains high interfragmentar compression and reduction of shear stress by one-half.
(18) In addition, the chains are tilted along one of the bisectors (omega = 0 degrees) of the hexagonal lattice (8 wide-angle maxima, 2 unique), a phase not previously reported in DPPC studies.
(19) At high relative humidities (higher than 90%, B form), the bisector of the less than OPO in the complexes forms an angle with respect to the helical axis which has a value lower by about 4 degrees than in the corresponding DNA sample.
(20) It has been proposed that these negative solid-angle illusions (assimilation effects) which occur in dual-angle (Bourdon-type) displays result from a failure to discriminate between the test (judged) edges and the bisectors of the solid angles.
Bivector
Definition:
(n.) A term made up of the two parts / + /1 /-1, where / and /1 are vectors.
