Tribrach

(1) In classical prosody, a foot consisting of three short syllables.

(2) In Russian versification, the term sometimes refers to a dactyl, amphibrach, or anapest that lacks an accent, for example:

Pervoe délo u deda—

Potolkovat’ s muzhikom.

(N. A. Nekrasov)

Such omissions were rare in the 19th century, occurring primarily in the first foot of a dactyl, as in the above example. In the 20th century they became more common and occurred both at the beginning of lines and in the middle of lines.

Other devices included Leica TC1800 electronic tachymeter, a micrometric table, a surveying tripod, three-axis photographic head--Manfrotto 405 Geared Head, geodetic tripod for engineering purposes with a jib, two tribrachs, two targets and the observation pillar.

The possibility of using close-range mono-photogrammetry in measuring relative displacements of rock blocks

The measurements are conducted in the Laboratory on the observation pillar equipped with the tribrach. By inserting the next plates under the base of the plummet the location of the optic fibre is inclined.

The use of optoelectronic techniques in studies of relative displacements of rock mass

One part originates in the near vicinity of the antenna (pillar/tripod, tribrach, mounting adapter, station marker, antenna ground plane, etc.), second part comes from more distant reflections.

Impact of some site dependent factors on GPS displacement monitoring

One part is invoked by the near field of the antenna (pillar/tripod, tribrach, adapter, marker, ground plane, etc.), second part comes from environment.

Results of four years monitoring of displacements of rock blocks in the Krkonose Mts

The traditional survey tool is a "total station," which is a conventional survey system with an instrument usually referred to as a gun, plus required prisms, poles, tripods, batteries, and tripod-mounted levels called tribrachs. Until recently, the Army version of this set was the Geodimeter[R] Automated Integrated Survey Instrument (AISI) 444.
