These can be divided into four types: paths extending infinitely to both directions, finite cycles of even length, infinite paths starting in the set A, and infinite paths starting in the set B ( the path passing through the element a in the diagram is infinite in both directions, so the diagram contains one path of every type ).

These two VLIW opcodes will be executed in two clock cycles, as opposed to the larger number required for the original code executed on an x86 processor which did not perform complex optimisations in hardware.

These are rough indications of the real factors that control when an oil change is appropriate, which include how long the oil has been run at elevated temperatures, how many heating cycles the engine has been through, and how hard the engine has worked.

These project management methodologies are based on the uncertainty of developing a new software system and advocate smaller, incremental development cycles.

These incremental or iterative cycles are timeboxed ( constrained to a known period of time, typically from one to four weeks ) and produce a working subset of the entire system deliverable at the end of each iteration.

These terms have historically been applied to any astronomical object orbiting the Sun that did not show the disk of a planet and was not observed to have the characteristics of an active comet, but as small objects in the outer Solar System were discovered, their volatile-based surfaces were found to more closely resemble comets, and so were often distinguished from traditional asteroids.

These villages, called pueblos by Spanish settlers, were often only accessible by rope or through rock climbing.

These surfacing stones were often placed in distinctive patterns.

These modifications are often essential for the function or regulation of a protein ; for example, the carboxylation of glutamate allows for better binding of calcium cations, and the hydroxylation of proline is critical for maintaining connective tissues.

These measured positions are then compared with those calculated by the laws of celestial mechanics: an assembly of calculated positions is often referred to as an ephemeris, in which distances are commonly calculated in astronomical units.

These and most other cities and large towns are now connected with asphalt-paved roads, while smaller towns are often connected by dirt roads, which may require a four-wheel-drive vehicle.

These Abrasax-stones often bear Hebraic names of God: Iao, Sabaoth, Adonai, Eloai.
