All seven recognized that independence was but the first step toward building a nation.

Many believe -- and understandably -- that the great difference between the Constitution of the Southern Confederacy and the Federal Constitution was that the former recognized the right of each state to secede.

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.

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.

It was symbolized ( at least for those of us who recognized ourselves in the image ) by that self-consuming, elegiac candle of Edna St. Vincent Millay's, that candle which from the quatrain where she ensconced it became a beacon to us, but which in point of fact would have had to be as tall as a funeral taper to last even the evening, let alone the night.

He recognized her because she was the one who, in a winter twilight, on the edge of camp, had once stopped him and reached down her hand to touch his fly.

It was recognized years ago that the transition from daytime to nighttime propagation conditions, and vice versa, is not an instantaneous process, but takes place over periods of time from roughly 2 hours before sunset until about 2 hours after sunset, and again from roughly 2 hours before sunrise until some 2 hours after sunrise.

Polyphosphates gave renewed life to soap products at a time when surfactants were a threat though expensive, and these same polyphosphates spelled the decline of soap usage when the synergism between polyphosphates and synthetic detergent actives was recognized and exploited.

The sampling program was instituted before the principles of probability sampling were widely recognized in population studies.

One day Maeterlinck, coming with a friend upon an event which he recognized as the exact pattern of a previous dream, detailed the ensuing occurrences in advance so accurately that his companion was completely mystified.

Shout at Eichmann though he might, the Prosecutor could not establish that the defendant was falsifying the way he felt about Jews or that what he did feel fell into the generally recognized category of anti-Semitism.

Thus, when Dartmouth's Winter Carnival -- widely recognized as the greatest, wildest, roaringest college weekend anywhere, any time -- was broadcast over a national television hookup, Prexy John Sloan Dickey appeared on the screen in rugged winter garb, topped off by a tam-o'-shanter which he confessed had been acquired from a Smith girl.

Long before he reached the protection of the stage door, Andy was recognized.

Returning to the school crossing, the officer was informed by the Sisk boy that he recognized the driver, a neighbor, and had obtained the license number.

This was a training ship and the training would continue, but there was an element of frightful absurdity here which Alexander recognized.

The APG III system ( 2009 ) differs only in that the Limnocharitaceae are combined with the Alismataceae ; it was also suggested that the genus Maundia ( of the Juncaginaceae ) could be separated into a monogeneric family, Maundiaceae, but the authors noted that more study was necessary before Maundiaceae could be recognized.

The family was one of the first to be recognized as a distinct group in Jacques Daleschamps ’ 1586 Historia generalis plantarum.

The rule, as was inevitable, was subject to frequent violations ; but it was not until the foundation of the Cluniac Order that the idea of a supreme abbot, exercising jurisdiction over all the houses of an order, was definitely recognized.

The lay abbot took his recognized rank in the feudal hierarchy, and was free to dispose of his fief as in the case of any other.

For this reason, the more uncertain skywave service was denominated `` secondary '' in our rules, as compared to the steadier, more reliable groundwave `` primary service '', and, for both skywave service and skywave interference, signal strength is expressed in terms of percentage of time a particular signal-intensity level is exceeded -- 50 percent of the time for skywave service, 10 percent of the time for skywave interference.

In 1947, affidavits were filed with the Commission by various clear-channel stations alleging that extensive interference was being caused to the service areas of these stations during daylight hours, from class 2, stations whose signals were being reflected from the ionosphere so as to create skywave intereference.

If a U. S .- based team ( located in either Boston, Chicago, Detroit or New York City ) was playing in Toronto on a particular Saturday night, thousands of fans in the U. S. city whose local team faced the Leafs would often listen to the CBC broadcast via skywave reception, with the game often drawing far more listeners during the HNIC broadcast period than any local station.

Originally, the use of HD Radio transmission on AM was limited to daytime only, and not allowed at night due to potential problems with skywave radio propagation.

One of the problems with providing coverage of an area the size of the UK was installing sufficient DF stations to cover the entire area to receive skywave signals reflected back from the ionised layers in the upper atmosphere.

As this antenna produced large amounts of skywave, the area of undistorted fading-free reception-was in spite of its high transmission power-at night not as large as planned and so it was planned to replace this antenna by an aerial with better skywave surpression.

As this antenna had an unfavorable vertical radiation pattern, which produced much skywave resulting in a too small fading-free reception area at night, in 1934 a new antenna was installed.

It is beamed at 96 degrees ( i. e. east ) and was originally mainly intended for night-time ( skywave ) coverage of Poland, Czechoslovakia, Hungary and the western USSR, key target areas for the BBC during the Cold War.

By night the skywave transmission was helped by extra power sometimes to as high as 150, 000 watts.

WBBM's skywave signal was received as far west as Salt Lake City, Utah.

The station's skywave signal was recently received in Salt Lake City, Utah.

Six radiomen told how, twice on two days after the ring was nabbed, a transmitter near Moscow was heard calling, using signals, times and wavelengths specified on codes found hidden in cigaret lighters in Lonsdale's apartment and the Krogers' house and also fastened to the transmitter lid.

He also paid close attention to his work quickly learning to distinguish the differing sounds the incoming telegraph signals produced and learned to translate signals by ear, without having to write them down and within a year was promoted as an operator.

When a group of different plant species was prompted by a variety of different stress signals, such as drought or cold, each plant responded uniquely.

This effect is now done electronically using DSP, but originally the effect was created by playing the same recording on two synchronized tape players, and then mixing the signals together.

The monochrome combinations still existing in the 1950s are standardized by the International Telecommunication Union ( ITU ) as capital letters A through N. When color television was introduced, the hue and saturation information was added to the monochrome signals in a way that black & white televisions ignore.

When analog television was developed, no affordable technology for storing any video signals existed ; the luminance signal has to be generated and transmitted at the same time at which it is displayed on the CRT.

One of the first devices used to amplify signals was the carbon microphone ( effectively a sound-controlled variable resistor ).

Subsequently, other listening stations – the Y-stations, ( such as the ones at Chicksands in Bedfordshire and Beaumanor Hall in Leicestershire where the headquarters of the War Office " Y " Group was located ) – gathered raw signals for processing at Bletchley.

It was a 5-bit code, with equal on and off intervals, which allowed telegraph transmission of the Roman alphabet and punctuation and control signals.

As a result, any possible preventive effect of the common official warning was cancelled by the mixed unofficial signals, and failed to prevent or to stop the war:

In the mid 20th century, a " codec " was hardware that coded analog signals into Pulse-code modulation ( PCM ) and decoded them back.

In time, cable television was widely established to carry available Canadian stations as well as import American stations, which constituted the vast majority of signals on systems ( usually only one or two Canadian stations, while some systems had duplicate or even triplicate coverage of American networks ).

The scheme was first published by Whitfield Diffie and Martin Hellman in 1976, although it was later alleged that it had been separately invented a few years earlier within GCHQ, the British signals intelligence agency, by Malcolm J. Williamson but was kept classified.

The Decca Navigator System was a low frequency radio navigation system which allowed ships and aircraft to determine their position by receiving radio signals from fixed navigational beacons with a receiving unit.

Position was calculated using a hyperbolic navigation system ( multilateration ) by comparing the phase difference of the radio signals received from several fixed stations.

The European Parliament stated in its report that the term ECHELON is used in a number of contexts, but that the evidence presented indicates that it was the name for a signals intelligence collection system.

The UKUSA intelligence community was assessed by the European Parliament ( EP ) in 2000 to include the signals intelligence agencies of each of the member states:

In 1895, Nikola Tesla was able to detect signals from the transmissions of his New York lab at West Point ( a distance of 80. 4 km / 49. 95 miles ).
