1phase — phaseless, adj. phasic, phaseal, adj. /fayz/, n., v., phased, phasing. n. 1. any of the major appearances or aspects in which a thing of varying modes or conditions manifests itself to the eye or mind. 2. a stage in a process of change or… …
2Phase — A phase is one part or portion in recurring or serial activities or occurrences logically connected within a greater process, often resulting in an output or a change. Phase or phases may also refer to:In science and engineering* Phase (matter),… …
3Condition monitoring — is the process of monitoring a parameter of condition in machinery, such that a significant change is indicative of a developing failure. It is a major component of predictive maintenance. The use of conditional monitoring allows maintenance to… …

5Phase rule — (Phys. Chem.) A generalization with regard to systems of chemical equilibrium, discovered by Prof. J. Willard Gibbs. It may be stated thus: The degree of variableness (number of degrees of freedom) of a system is equal to the number of components …
6Phase detector — A phase detector is a frequency mixer or analog multiplier circuit that generates a voltage signal which represents the difference in phase between two signal inputs. It is an essential element of the phase locked loop (PLL).Detecting phase… …
7Phase transition — This diagram shows the nomenclature for the different phase transitions. A phase transition is the transformation of a thermodynamic system from one phase or state of matter to another. A phase of a thermodynamic system and the states of matter… …
