These early water clocks were calibrated with a sundial.

These mechanisms were found in some types of synchronous-motor-driven electric clocks.

These deductions are logical consequences of the stated assumptions, and are general properties of space-time, typically without regard to a consideration of properties pertaining to the structure of individual objects like atoms or stars, nor to the mechanisms of clocks.

These precision pendulum-clocks are thought by some to have been the most accurate clocks in the world at the time, and significantly are the direct link to the sea clocks.

These older styles of slave clocks either keep time by themselves, and are corrected by the master clock, or require impulses from the master clock to advance.

These secondary clocks appear to run like an ordinary plug-in electric clock and run on their own synchronous electric motor and will maintain correct time unless there is an interruption in electric service, depending on the master clock only for the periodic synchronizing impulse.

These early techniques have been replaced by newer ones based on mitochondrial DNA sequences and molecular phylogenetics approaches that make use of computational procedures for sequence alignment, construction of phylogenetic trees and calibration of molecular clocks to infer evolutionary relationships.

These were also used to make clocks and watches, and to make small arms.

: These are devices such as atomic ( cesium, rubidium ) clocks, GPS clocks or other radio clocks.

These automatic signal clocks were synchronization | synchronized by telegraphy in 1905 before the widespread use of radio

These clocks, however, are only as good as the clockwork that activates them ; they have improved substantially since the first surviving clocks from the 14th century.

These papers relate to such concepts as logical clocks ( and the happened-before relationship ) and Byzantine failures.

These clocks were designed with special compartments where an entry band, removed from the returning race bird was placed.

These models are called relaxed molecular clocks because they represent an intermediate position between the ' strict ' molecular clock hypothesis and Felsenstein's many-rates model and are made possible through MCMC techniques that explore a weighted range of tree topologies and simultaneously estimate parameters of the chosen substitution model.

These included a portable water-powered scribe clock, which was a meter high and half a meter wide, reconstructed successfully at the Science Museum ( London ) in 1976 Al-Jazari also invented monumental water-powered astronomical clocks which displayed moving models of the Sun, Moon, and stars.

These included geared clocks and a portable water-powered scribe clock, which was a meter high and half a meter wide.

These early paperback editions have " a white cover showing a man in a spacesuit with a sword, with symbolic clocks all around ," according to the author, with alternatively the first hardcover edition featuring a large hourglass with planets falling through it.

These glasses are turned when there is a division ; one of the four-minute glasses is turned and the bells will ring and the clocks will flash green for the House of Representatives or red for the Senate for four minutes.

These clocks are housed in an environmentally controlled and electromagnetically shielded room to prevent outside interference with the clocks.

These tubes may differ both in the choice of the electron optical system and in the design of the coupling members.

These three differ from each other in the way they treat vowels: abjads have letters for consonants and leave most vowels unexpressed ; abugidas are also consonant-based, but indicate vowels with diacritics to or a systematic graphic modification of the consonants.

These trees differ from the birches ( Betula, the other genus in the family ) in that the female catkins are woody and do not disintegrate at maturity, opening to release the seeds in a similar manner to many conifer cones.

These types of membranes differ in lipid and protein composition.

These processes differ in the means by which chemical reactions are initiated ( e. g., activation process ) and process conditions.

These two mechanisms differ in the stereochemistry of the products.

These differ in having stouter, woodier stems forming taller shrubs, and in the bell-shaped flowers, the petals not being reflexed.

These single-function devices differ from the more familiar general-purpose CPUs in several ways:

These novels differ from the Western tradition in several points as described by van Gulik:

These organizations ' customs and practices differ widely.

These parties belong to all sides of the political spectrum so the reasons for their Euroscepticism may differ, but they all opposed the ratification of the Treaty of Lisbon.

These four schools share most of their rulings, but differ on the particular hadiths they accept as authentic and the weight they give to analogy or reason ( qiyas ) in deciding difficulties.

These differ from one island to another.

These differ in how the weight of the load is attached.

These machines are mechanically similar since all three types use a handle connected to a flywheel by rope, chain, or strap to provide resistance to the user – the types differ only in braking mechanism.

These differ from automatic or switchblade knives in that the blade is not released by means of a button or catch on the handle ; rather, the blade itself is the actuator.

These two polymorphs differ by a " kinking " of bonds ; this change in structure gives β-quartz greater symmetry than α-quartz, and they are thus also called high quartz ( β ) and low quartz ( α ).

These two cells are identical and do not differ in any way from the original parent cell.

These two versions also differ from each other in their readings of numerous words.

These codes and responsa may differ from each other as regards detail ( and reflecting the above differences, on the weight assigned to various issues ).

These forms differ in terms of the relative orientations of the constituent P < sub > 4 </ sub > tetrahedra.

These two styles differ mainly in the way in which they handle quotation marks.

These differ from conventional PLC types as being suitable for use in safety-critical applications for which PLCs have traditionally been supplemented with hard-wired safety relays.

These systems differ in what they measure, what unit of measurement they use, and where the size 0 ( or 1 ) is positioned.

These differ from the normal disfluencies found in all speakers in that stuttering disfluencies may last longer, occur more frequently, and are produced with more effort and strain.
