(mathematics)
Property of two nonzero vectors in a vector space over the real numbers such that one vector equals the product of the other vector and a negative number.
(physics)
Property of two displacements or other vectors which lie along parallel lines but point in opposite directions.

4 provides a simple nonlinear component consists of an anti-paralleled HSMS-282C Schottky diodes pair welded at the center of the conductor strip of a 50 [ohm] microstrip line printed on a 1mm thick substrate with relative dielectric constant [[epsilon].sub.r] = 2.65.
It has been demonstrated that the capacitive gaps represent the radiated elements while the inductive meander lines are non-radiating due to the anti-parallel currents flowing on each pair of inductive meander lines.
4 consists of a MOSFET S1 with an intrinsic anti-parallel diode and an IGBT, [S.sub.2] with a fast recovery diode D connected in anti- parallel and the capacitor [C.sub.o]
Each shunt capacitor in the SVC system is divided into a specified number of branches that are switched on and off via anti-parallel thyristor/diode switches.
The third way to implement a SHM is based on the technique called anti-parallel diode pair (APDP).
coli show it has a typical lipocalin fold consisting of eight anti-parallel beta-strands that form a beta-barrel with a distinct binding pocket for a small molecule.
This self-organized network of actin filaments resembles the cytokinetic ring of dividing cells in the following ways: (i) it exhibits myosin-II-mediated, anti-parallel sliding of actin filaments (4, 5), and (ii) it assembles during the M-phase of the cell cycle.
In longitudinal recording, the magnetization in the bits on a disc is flipped between lying parallel and anti-parallel to the direction in which the head is moving relative to the disc.
By applying magnetic field impulses perpendicular to the direction of magnetization rather than anti-parallel to it, the magnetic poles of spinning particals can be flipped over or reversed in picoseconds rather than the nanoseconds it currently takes.
When looking at convertor design and cost there is little to choose between a single-ended armature with reversing field and a fixed rectifier with an anti-parallel armature.
