In geometry, parallel lines are straight lines that run alongside one another and never intersect. They share a common trait, which is that they maintain a constant distance between them. Determining ...

Abstract: In this paper, a wideband transversal filter with notch is proposed. A parallel-coupled line with U-shaped slot is proposed as transversal section. Phase performance is studied and found ...

Abstract: An ultra-wideband (UWB) bandpass-filtering microstrip circuit with an embedded in-band transmission zero (TZ) for co-integrated angular displacement RF sensing is reported. It is based on a ...

If you drive a car built since 2018, a rearview camera came standard, but they actually started popping up as options on cars more than a decade before that. And while many early examples were ...

Alternate interior angles are pairs of equal angles formed on opposite sides of a transversal, but inside two parallel lines. Angles of elevation and depression are alternate interior angles. That is, ...

Horizontal lines run left to right, parallel to the horizon, with slope 0 and equation y = k. Vertical lines run top to bottom, perpendicular to the horizon, with undefined slope and equation x = k.

THIRUVANANTHAPURAM: In what could accelerate railway development in the state, the state will soon have third and fourth railway lines parallel to the existing double lines. After his meeting with ...

“I think that maybe it’s not two circles but one,” says Sebastian, the protagonist of Edward St Aubyn’s scintillating new novel Parallel Lines to his newly discovered sister, Olivia. They are looking ...
