Mathematically, this means that for a causal linear system to be stable all of the poles of its transfer function must have negative-real values, i. e. the real part of all the poles are less than zero.

Sometimes it would be desired to obtain particular dynamics in the closed loop: i. e. that the poles have < math > Re

The most commonly used ammunition were stones, but “ darts and sharp wooden poles ” could be substituted if necessary.

The two ends of a bar magnet are referred to as poles ( not to be confused with monopoles ), and are labeled " north " and " south.

Thus, the gamma function must be undefined at those points ; it is a meromorphic function with simple poles at the nonpositive integers.

Even though a magnet is said to have a north pole and a south pole, these two poles cannot be separated from each other.

Paul Dirac observed in 1931 that, because electricity and magnetism show a certain symmetry, just as quantum theory predicts that individual positive or negative electric charges can be observed without the opposing charge, isolated South or North magnetic poles should be observable.

Rollers generally have a handle that allows for different lengths of poles to be attached, allowing painting at different heights.

A relay will switch one or more poles, each of whose contacts can be thrown by energizing the coil in one of three ways:

A less extreme possibility would be that it was merely the Earth's magnetic pole that wandered to this inclination, as the magnetic readings which suggested ice-filled continents depends on the magnetic and rotational poles being relatively similar.

Water ice should also be in other permanently shadowed craters near the lunar poles.

While in the USA modern jazz and electric R & B may have represented opposite poles of blues-based Afro-American music, however, the British pop music of the beat boom developed out of the skiffle and R & B championed by well-known jazzmen such as Chris Barber.

# Magnetic poles ( or states of polarization at individual points ) attract or repel one another in a similar way and always come in pairs: every north pole is yoked to a south pole.

Given significant distance from the magnetic poles, one can figure which hand is which using a magnetic compass and the sun.

Since each chromosome has only one functional unit of a pair of kinetochores, whole chromosomes are pulled toward opposing poles, forming two haploid sets.

It is also known as ' dominant pole compensation ' because it introduces a dominant pole ( one which masks the effects of other poles ) into the open loop frequency response.

The " dualism " of Clausewitz's view of war ( i. e., that wars can vary a great deal between the two " poles " he proposed, based on the political objectives of the opposing sides and the context ) seems simple enough, but few commentators have proven willing to accept this crucial variability — they insist that Clausewitz " really " argued for one end of the scale or the other.

S .), or sometimes ( in the UK, as well as in Seattle and Vancouver ) simply trolleys.

From Earth, Vega is being observed from the direction of one of these poles.

The displacement of mercury which took place when the cell was short-circuited, only took place very slowly when an ebonite plate, covered with a sheet of copper of high resistance, was inserted between one of the poles of the cell, and the corresponding electrode of the electrometer ; but when sparks were produced by a machine, the mercury was rapidly thrown into the capillary tube owing to the sudden diminution in the resistance of the plate.

The track laying was divided up into various parts: one gang laid rails on the ties, drove the spikes, and bolted the splice bars ; at the same time, another gang distributed telegraph poles and wire along the grade, while the cooks prepared dinner and the clerks busied themselves with accounts, records, using telegraph wire to tap for more materials and supplies.

In theory, it is possible for a magnetic sail to launch directly from the surface of a planet near one of its magnetic poles, repelling itself from the planet's magnetic field.
