The American people have indeed come a long way in the brief interval between 1930 and 1961.

In my recollection, there was a long interval between the death of the officer and the appearance of the first of the retreating redcoats, and in that interval the dust cloud over the road seems to hover indefinitely.

All the incidents subsequent to the appeal of Athens to Sparta are expressly referred by Herodotus to the interval between the sending of the heralds in 491 BC and the invasion of Datis and Artaphernes in 490 BC ( cf.

Antiderivatives are related to definite integrals through the fundamental theorem of calculus: the definite integral of a function over an interval is equal to the difference between the values of an antiderivative evaluated at the endpoints of the interval.

Bouts consist of three rounds of three minutes in the Olympic and Commonwealth Games, and three rounds of three minutes in a national ABA ( Amateur Boxing Association ) bout, each with a one-minute interval between rounds.

The length of the interval between two such successive events may be allowed to vary slightly during the year, or it may be averaged into a mean solar day.

A review of all randomized controlled trials in the scientific literature by the Cochrane Collaboration published in JAMA in 2007 found that β-carotene increased mortality by something between 1 and 8 % ( Relative Risk 1. 05, 95 % confidence interval 1. 01-1. 08 ).

The Euler – Maclaurin formula provides expressions for the difference between the sum and the integral in terms of the higher derivatives ƒ < sup >( k )</ sup > at the end points of the interval m and n. Explicitly, for any natural number p, we have

For example, if a newborn baby's heart beats at a frequency of 120 times a minute, its period ( the interval between beats ) is half a second.

If we do not attempt to look back at an event, the greater the interval time between the time when the event from happening and the time when we try to remember, the memory will start to fade.

The time interval between similar lunar phases — the synodic month — averages about 29. 53 days.

Therefore, a degree on the Fahrenheit scale is of the interval between the freezing point and the boiling point.

On October 1, 1962, Groucho, after acting as occasional guest host of The Tonight Show during the six-month interval between Jack Paar and Johnny Carson, introduced Carson as the new host.

In 1343 the interval between Holy Years was reduced by Pope Clement VI to fifty years.

* Induction period-the time interval between the initial cause and the appearance of the first measurable effect

* Space-time interval, the distance between two points in 4-space

The intermediate value theorem states the following: If f is a real-valued continuous function on the interval b, and u is a number between f ( a ) and f ( b ), then there is a c ∈ b such that f ( c ) = u.

It later become clear that the established ten-year interval between revisions was too short.

The open interval ( a, b ) has the same measure, since the difference between the two sets consists only of the end points a and b and has measure zero.

Since relativity postulates that the speed of light is the same for all observers, the Lorentz transformation must preserve the spacetime interval between any two events in Minkowski space.

The interval between the posterior commissure of the labia majora and the anus, from 2. 5 to 3 cm.

In North America, where the interval consists primarily of marine limestones, it was in the past treated as a full-fledged geologic period between the Devonian and the Pennsylvanian.

Jitter refers to the abnormal variation in the time interval between action potentials of adjacent muscle fibers in the same motor unit.

He measured the period of his pendulum very accurately using the clock pendulum by the method of coincidences ; timing the interval between the coincidences when the two pendulums were swinging in synchronism.

The interval between clock signals is designed to be long enough to allow the outputs of the memory elements to " settle " so they are not changing when the next clock comes.

where Δt is the time interval between two co-local events ( i. e. happening at the same place ) for an observer in some inertial frame ( e. g. ticks on his clock ), this is known as the proper time, Δ < var > t '</ var > is the time interval between those same events, as measured by another observer, inertially moving with velocity v with respect to the former observer, v is the relative velocity between the observer and the moving clock, c is the speed of light, and

: dt < sub > E </ sub > is a small increment of proper time t < sub > E </ sub > ( an interval that could be recorded on an atomic clock );

A time interval measurement involves two interpolations because the start and stop events are not synchronized to the clock.

The least recently used page ( LRU ) replacement algorithm, though similar in name to NRU, differs in the fact that LRU keeps track of page usage over a short period of time, while NRU just looks at the usage in the last clock interval.

At each clock interval, all pages that have been referenced within that interval will have their counter incremented by 1.

* Scheduled-task pattern: A task is scheduled to be performed at a particular interval or clock time ( used in real-time computing )

On the other hand, since the system is immersed in a gravitational potential which varies with the position, according to the principle of equivalence the uncertainty in the position of the clock implies an uncertainty with respect to its measurement of time and therefore of the value of the interval.

In synchronous DRAM, the interval is specified in clock cycles.

Although this interval is still orders of magnitude longer than the Planck time, other experiments currently coming online including the Planck Surveyor probe, promise to push back our ' cosmic clock ' further to reveal quite a bit more about the very first moments of our universe's history, hopefully giving us some insight into the Planck epoch itself.

So, if John sees a clock that is at rest in Bill's frame record one second, John will find that his own clock measures between these same ticks an interval t, called coordinate time, which is greater than one second.

Alternatively, these equations for time dilation and length contraction ( here obtained from the invariance of the spacetime interval ), can be obtained directly from the Lorentz transformation by setting for time dilation, meaning that the clock is at rest in Bill's frame, or by setting for length contraction, meaning that John must measure the distances to the end points of the moving rod at the same time.

It is then possible for the impulse duration and the summing interval to be defined by the same clock with a suitable arrangement of logic and counters.

Many particular implementations seek to define the impulse duration and the summing interval from the same clock as discussed above but in such a way that the start of the impulse is delayed until the next occurrence of the appropriate clock pulse boundary.

Although the Sigma-Delta converter is generally implemented using a common clock to define the impulse duration and the summing interval it is not absolutely necessary and an implementation in which the durations are independently defined avoids one source of noise, the noise generated by waiting for the next common clock boundary.

The principle of their function lies in detecting the vertical synchronization signal, and forcing the lines occurring during the vertical blanking interval to black level, removing the AGC-confusing pulses.

Two pulses of current are then expected not to occur for a duration equal or larger than the time interval between two consecutive pulses of voltage.

By measuring the time interval between these pulses, the gas velocity is calculated as where is the distance between the laser beams and is the time interval.

This produces a very precise interval between pulses that range from roughly milliseconds to seconds for an individual pulsar.

Nor is it clear whether it concerned two sharp mass extinctions or a series of smaller extinctions, though the latest research suggests multiple causes and a series of distinct extinction pulses through an interval of some three million years.

The ADC converts the mean of an analog voltage into the mean of an analog pulse frequency and counts the pulses in a known interval so that the pulse count divided by the interval gives an accurate digital representation of the mean analog voltage during the interval.

The interval between pulses, p, is determined by a feedback loop arranged so that.

The interval between pulses is proportional to the inverse of the mean of the input voltage during that interval and thus over that interval, ts, is a sample of the mean of the input voltage proportional to V / ts.

The refocusing will not be perfect for protons that have moved during the time interval between the pulses, and the signal measured by the MRI machine is reduced.

The type of power dissipation, whether continuous or pulsed, affects the maximum operating temperature, due to thermal capacitance characteristics ; in general, the lower the frequency of pulses for a given power dissipation, the higher maximum operating ambient temperature, due to allowing a longer interval for the device to cool down.
