In mathematics, a heteroclinic cycle is an invariant set in the phase space of a dynamical system . It is a topological circle of equilibrium point s and connecting heteroclinic orbit s. If a heteroclinic cycle is asymptotically stable, approaching trajectories spend longer and longer periods of time in a neighbourhood of successive equilibria. Robust heteroclinic cycles A robust heteroclinic cycle is one which persists under small changes in the underlying dynamical system. Robust cycles often arise in the presence of symmetry or other constraints which force the existence of invariant hyperplanes. An prototypical example of a robust heteroclinic cycle is the Guckenheimer&ndash Holmes cycle.

A symphonic song cycle can either refer to a symphony composed of separate Movement music movements played consecutively or to a set of symphonic works linked by theme, common composer, or common conductor. A symphonic cycle should not be confused with the closely related song cycle . Symphonic cycle as a whole symphonic work A symphony is essentially cyclic in nature, typically containing four interconnected movements as part of a larger work. At first the movements of a symphony were meant to be distributed among other works arias , overtures , concertos in extended evening social events at which music served a background or occasionally center role. The movements were meant to be connected and identified as part of the symphonic cycle through recall and quotation of earlier movements, and the finale movement meant to be seen as a destination and recap. It was not until Beethoven that a symphonic cycle came to be seen as a work needing isolated, consecutive play of the constituent movements. ref cite book last Brown first A.

Thermodynamics cTopic Processes and Cycles The Vuilleumier cycle is a thermodynamic cycle with applications in low temperature Refrigeration cooling . In some respects it resembles a Stirling cycle or engine, although it has two displacer s with a mechanical linkage connecting them as compared to one in the Stirling cycle. The hot displacer is larger than the cold displacer. The coupling maintains the appropriate phase difference . The displacers do no work emdash they are not pistons. Thus no work is required in an ideal case to operate the cycle. In reality friction and other losses mean that some work is required. Devices operating on this cycle have been able to produce Thermodynamic temperature temperature s as low as 15 Kelvin K using liquid nitrogen to pre cool. Without precooling 77 K was reached with a heat flow of 1 W. The cycle was first patented by Vuilleumier in 1918, and again in Leiden by KW Taconis in 1951.

The Greek astronomer Hipparchus introduced two cycles that have been named after him in later literature. The first is described in Ptolemy s Almagest IV.2. Hipparchus constructed a cycle by multiplying by 17 a cycle due to the Chaldea n astronomer Kidinnu , so as to closely match an integer number of synodic month s 4267 , anomalistic month s 4573 , years 345 , and days 126007 about 1 hour it is also close to a half integer number of draconic month s 4630.53... , so it is an eclipse cycle . By comparing his own eclipse observations with Babylonian records from 345 years earlier, he could verify the accuracy of the various periods that the Chaldean astronomers used. The second is a calendar cycle Hipparchus proposed a correction to the Calippic cycle of 76 years , which itself was proposed as a correction to the Metonic cycle of 19 years . He may have published it in the book Peri eniaus ou meg thous On the Length of the Year , which is lost. From solstice observations, Hipparchus found that the tropical year is about 1 300 of a day shorter than the 365 1 4 days that Calippus used see Almagest III.1 . So he proposed to make a 1 day correction after 4 Calippic cycles, such that 304 years 3760 lunations 111035 days. This is a very decent approximation for an integer number of lunations in an integer number of days error only 0.014 days . But it is in fact 1.37 days longer than 304 tropical years the mean tropical year is actually about 1 128 day 11 minutes 15 seconds shorter than the Julian year calendar Julian calendar year of 365.25 days. These differences cannot be corrected with any cycle that is a multiple of the 19 year cycle of 235 lunations it is an accumulation of the mismatch between years and months in the basic Metonic cycle, and the lunar months need to be shifted systematically by a day with respect to the solar year i.e. the Metonic cycle itself needs to be corrected after every 228 years.
