Such sensors had been used to monitor Chinese missile tests, Soviet laser activity, military movements, and foreign nuclear programs.

Such a system would involve a ' spotter ' satellite, which would identify targets from orbit with high-power sensors, and a nearby ' magazine ' satellite to de-orbit a long, needle-like tungsten dart onto it with a small rocket motor or just dropping a very big rock from orbit ( such as an asteroid ).

Such systems are sometimes called infrared search and track sensors.

Such a processor could form the basis of a robot which, using artificial sensors, interact with its surroundings in a way which mimics living creatures.

Such sensors exist in many different variants depending on the manufacturer and camera model.

Such issues led to developments of other genetically encoded calcium sensors including the calmodulin-based sensor cameleon ,< ref > developed by Roger Tsien and the troponin-based sensor, TN-XXL, developed by Oliver Griesbeck.

Such activity may or may not have irritated the Kremlin, but it has frequently condemned America to an unnatural defensiveness that has undermined our effort to give leadership to the free world.

Such study may take many forms.

Such an interferometer provides a means of absolute temperature measurement, and may be used as an alternative to the gas thermometer.

Such payments, and applications for such payments, shall be made in accordance with such regulations as the Secretary of the Treasury may prescribe.

Such classifications may be called `` somewhat advanced '' or `` somewhat delayed '', as the case may be, reserving `` moderate '' for dots upon or close to the mean.

Such needs may rise to pathological proportions.

Such altruism may only extend to ingroup members while there may instead prejudice and antagonism against outgroup members ( See also in-group favoritism ).

Such an anagram may be a synonym or antonym of its subject, a parody, a criticism, or praise ; e. g. George Bush = He bugs Gore ; Madonna Louise Ciccone = Occasional nude income or One cool dance musician ; William Shakespeare = I am a weakish speller, Roger Meddows Taylor = Great words or melody.

Such an act may be referred to as an " act of hubris ", or the person committing the act may be said to be hubristic.

Such statements may be misleading because they do not reflect differences in strength of the various kinds of wines, beers, and spirits.

Such information may not be amenable to analysis by other means ( e. g. TEM ) owing to the difficulty in generating a three dimensional dataset with composition.

Such mines may be visited in the Kinzig valley, the Suggental, the Muenster valley, and around Todtmoos.

Such names have not yet been shown conclusively to predate the twelfth century, but there are indications that they may be considerably older.

Such sightings and stories may simply be a more modern manifestation of earlier stories of mythical black dogs and other such creatures in remote areas of Britain, such as those that inspired The Hound of the Baskervilles.

Such broad scope of the book may be the reason the Chronicler commences his genealogy with Adam.

Such numbers may have amounted to a substantial proportion, if not all, of the Peucini Bastarnae: Victor claims that the Carpi resettled in Pannonia by Diocletian at the same time, together with those previously transferred by Aurelian, amounted to the entire Carpi tribe.
