For an elliptic filter, it happens that, for a given order, there exists a relationship between the ripple factor and selectivity factor which simultaneously minimizes the Q-factor of all poles in the transfer function:

Each curve represents four poles, since complex conjugate pole pairs and positive-negative pole pairs have the same Q-factor.

This sensitivity is inversely proportional to the quality factor ( Q-factor ) of the poles of the transfer function of the filter.

The left side spline interface looks similar, but is in fact different to prevent installation of older ISIS Drive crankarms — which are no longer compatible because Q-factor and chainline can not be maintained using these older cranks with an external bearing BB.

The complexity of these algorithms is higher though, as up to calls to estimate the Q-factor are required.

The Q-factor ( quality factor ) is given by Q = f < sub > r </ sub >/ w.

The “ dissipation ”, D, is the inverse of the Q-factor: D = Q < sup >− 1 </ sup > = w / f < sub > r </ sub >.

Crystals have very high Q-factor and also better temperature stability than tuned circuits, so crystal oscillators have much better frequency stability than LC or RC oscillators.

The signal bandwidth of the amplifier is limited by the Q-factor of the tuned circuit but this is not a serious limitation.

The disadvantage is this may increase the Q-factor of the stoker's cranks and may also cause " heel-strike " of the stoker's shoes on the chain stays.

A band-pass filter can be characterised by its Q-factor.

The Q-factor is the inverse of the fractional bandwidth.

As long as the Q-factor is not too low, damping does not result in a lower sensitivity.

VCOs generally have the lowest Q-factor of the used oscillators, and so suffer more jitter than the other types.

Another distinction is that AQoS uses the Q-factor as the link cost.

The Chicago Cubs retired numbers are commemorated on pinstriped flags flying from the foul poles at Wrigley Field, with the exception of Jackie Robinson, the Brooklyn Dodgers player whose number 42 was retired for all clubs.

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.

Continuous-time LTI filters may also be described in terms of the Laplace transform of their impulse response, which allows all of the characteristics of the filter to be analyzed by considering the pattern of poles and zeros of their Laplace transform in the complex plane.

However, in reality, according to the United States Flag Code, all state flags are displayed at the same height as the American flag when on separate poles, with the American flag in a position of honor ( to its own right ).

This integral function is extended by analytic continuation to all complex numbers except the non-positive integers ( where the function has simple poles ), yielding the meromorphic function we call the gamma function.

Aside from some craters near the lunar poles such as Shoemaker, all parts of the Moon see around 14. 77 days of sunlight followed by 14. 77 days of " night " ( there is no permanently " dark side " of the Moon ).

Due to a missing jet stream, fading spots, and slower activity near the poles, independent scientists of the National Solar Observatory ( NSO ) and the Air Force Research Laboratory ( AFRL ) now ( 2011 ) predict that the next 11-year solar sunspot cycle, Cycle 25, will be greatly reduced or may not happen at all.

* Nordic walking, walking with ski poles in both hands, this form of walking simultaneously mobilises all motor organs and hence produces a greater cardio vascular workout than most walking styles.

Almost all of the track work was done manually, using shovels, picks, axes, black powder, two-wheeled dump carts, wheelbarrows, ropes, mules, and horses, while supply trains carried all the necessary material for the construction, which consisted of “ ties, rails, spikes, bolts, telegraph poles, wire, etc .”

* In civilian telecommunications, outside plant refers to all of the physical cabling and supporting infrastructure ( such as conduit, cabinets, tower or poles ), and any associated hardware ( such as repeaters ) located between a demarcation point in a switching facility and a demarcation point in another switching center or customer premises.

This structure requires four long and large poles ( these should all be nearly equal in length ), and 4-16 medium-sized poles.

The patient is assisted by an anesthesiologist or resident to make a specific surgical position, then sterile drapes are used to cover all of the patient's body except for the head and the surgical site or at least a wide area surrounding the operating field ; the drapes are clipped to a pair of poles near the head of the bed to form an " ether screen ", which separates the anesthetist / anesthesiologist's working area ( unsterile ) from the surgical site ( sterile ).

Due to the attention received by the totem pole, additional totem poles were placed at each of the locations and all the store began operating under the name " Tot ' em Stores " ( a word play on the totem poles as well as the idea that customers toted away their purchases ).

As the celestial sphere is considered infinite in radius, all observers see the celestial equator, celestial poles and ecliptic at the same place against the background stars.

As the Earth spins, the celestial poles remain nearly fixed in the sky, and all other points seem to rotate around them.

The graticule perspective is based on this designation: As the longitudinal rings — geographically defined, all great circles — converge at the poles, it is the poles that the conjugate graticule is defined.

If the polar vertex is " pulled down " 90 °, so that the vertex is on the equator, or transverse diameter, then it becomes the transverse graticule, upon which all spherical trigonometry is ultimately based ( if the longitudinal vertex is between the poles and equator, then it is considered an oblique graticule ).

The larger moons, however, since they are all tidally locked, are scalene, squat at the poles but with the equatorial axis directed at their planet longer than the axis along their direction of motion.

this is not so, for education offers all kinds of dividends, including how to pull the wool over a husband's eyes while you are having an affair with his wife.

Most of them are Democrats and nearly all consider themselves, and are viewed as, liberals.

Or else the North really believes that all Southerners except a few quaint old characters have come around to realizing the errors of their past, and are now at heart sharers of the American Dream, like everybody else.

Unless all gadgets are properly operated -- and the wires and seals from the handles removed first -- no damage can be done.

These things are important to almost all Persians and perhaps most important to the most ordinary.

These are traversed by another line of vaults, and thus rooms, arched on all four sides, are formed.

These songs ( practically all Persian music, for that matter ) are limited to a range of two octaves.

Their consequences are irrelevant -- or there are no consequences at all.

We began by declaring that all men are created equal.

We now practically read it, all men are created equal except Negroes.

They recognized that slavery was a moral issue and not merely an economic interest, and that to recognize it explicitly in their Constitution would be in explosive contradiction to the concept of sovereignty they had set forth in the Declaration of 1776 that `` all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among them are life, liberty and the pursuit of happiness.

Lucretius has remarked: `` The reason why all Mortals are so gripped by fear is that they see all sorts of things happening in the earth and sky with no discernable cause, and these they attribute to the will of God ''.

Often it is recognized that all the details of the pattern may not be essential to the outcome but, because the pattern was empirically determined and not developed through theoretical understanding, one is never quite certain which behavior elements are effective, and the whole pattern becomes ritualized.

We have staved off a war and, since our behavior has involved all these elements, we can only keep adding to our ritual without daring to abandon any part of it, since we have not the slightest notion which parts are effective.

the tricks that time plays with memory and memory with time are queerest of all.

the miraculous way in which music, revelation and death are associated in a single instant -- all this seems a triumph of art, a rather desperate art, in itself ; ;

The Poetics, in affirming that all human arts are `` modes of imitation '', gives a more serious role to artistic mimesis than did Plato.
