Definition of Phase

phase
1. The offset of one's waking-sleeping schedule with respect to the standard 24-hour cycle; a useful concept among people who often work at night and/or according to no fixed schedule. It is not uncommon to change one's phase by as much as 6 hours per day on a regular basis. "What's your phase?" "I've been getting in about 8 P.M. lately, but I'm going to wrap around to the day schedule by Friday." A person who is roughly 12 hours out of phase is sometimes said to be in "night mode". (The term "day mode" is also (but less frequently) used, meaning you're working 9 to 5 (or, more likely, 10 to 6).) The act of altering one's cycle is called "changing phase"; "phase shifting" has also been recently reported from Caltech.
2. "change phase the hard way": To stay awake for a very long time in order to get into a different phase.
3. "change phase the easy way": To stay asleep, etc. However, some claim that either staying awake longer or sleeping longer is easy, and that it is *shortening* your day or night that is really hard (see wrap around). The "jet lag" that afflicts travelers who cross many time-zone boundaries may be attributed to two distinct causes: the strain of travel per se, and the strain of changing phase. Hackers who suddenly find that they must change phase drastically in a short period of time, particularly the hard way, experience something very like jet lag without travelling.

"I've been getting in about 8 P.M. lately, but I'm going to wrap around to the day schedule by Friday." A person who is roughly 12 hours out of phase is sometimes said to be in `night mode'. (The term `day mode' is also (but less frequently) used, meaning you're working 9 to 5 (or, more likely, 10 to 6).) The act of altering one's cycle is called `changing phase'; `phase shifting' has also been recently reported from Caltech. 2. `change phase the hard way': To stay awake for a very long time in order to get into a different phase. 3. `change phase the easy way': To stay asleep, etc. However, some claim that either staying awake longer or sleeping longer is easy, and that it is shortening your day or night that is really hard (see wrap around).

Phase
Refers to the timing relationship of two or more signals or soundwaves. In phase means that the speakers are moving in and out at the same time.

If your speakers are out of phase you'll hear significantly less bass, and the sounds will localize to the individual speakers.

phase
In joint operation planning, a definitive stage of an operation or campaign during which a large portion of the forces and capabilities are involved in similar or mutually supporting activities for a common purpose. (JP 5-0)
  

Phase
(n.)
That which is exhibited to the eye; the appearance which anything manifests, especially any one among different and varying appearances of the same object.
  
(n.)

(n.)
Any appearance or aspect of an object of mental apprehension or view; as, the problem has many phases.
  
(n.)
A particular appearance or state in a regularly recurring cycle of changes with respect to quantity of illumination or form of enlightened disk; as, the phases of the moon or planets. See Illust. under Moon.

phase
\phase\ (?), v. t. [cf. feeze.] to disturb the composure of; to disconcert; to nonplus. [colloq.]
phase
\phase\ (?), n.
1. (phys. chem.) a homogenous, physically distinct portion of matter in a system not homogeneous; as, the three phases, ice, water, and aqueous vapor. a phase may be either a single chemical substance or a mixture, as of gases.
2. (zo?l.) in certain birds and mammals, one of two or more color variations characteristic of the species, but independent of the ordinary seasonal and sexual differences, and often also of age. some of the herons which appear in white and colored phases, and certain squirrels which are sometimes uniformly blackish instead of the usual coloration, furnish examples. color phases occur also in other animals, notably in butterflies.
3. (elec.) the relation at any instant of a periodically varying electric magnitude, as electro-motive force, a current, etc., to its initial value as expressed in factorial parts of the complete cycle. it is usually expressed in angular measure, the cycle beb four right angles, or 360°. such periodic variations are generally well represented by sine curves; and phase relations are shown by the relative positions of the crests and hollows of such curves. magnitudes which have the same phase are said to be in phase.

Phase
N
Passover; Jewish feast; paschal lamb/sacrifice at the Passover

phase
1. any portion of a nonhomogeneous system that is bounded by a surface, is homogeneous throughout, and may be mechanically separated from the other phases. The three phases of HgO, for example, are ice (solid), water (liquid), and steam (gas). 2. in physics, the stage or point in a cycle to which a rotation, oscillation, or variation has advanced.

Phase
The timing relationship between two signals. (Audio/Electronics)

Phase
wek, wek-tor

phase
1. Of a periodic, varying phenomenon, e.g., an electrical signal or electromagnetic wave, any distinguishable instantaneous state of the phenomenon, referred to a fixed reference or another periodic varying phenomenon. (188 ) Note 1: Phase, i.e., phase time (frequently abbreviated simply to "phase" in colloquial usage), can be specified or expressed by time of occurrence relative to a specified reference. Note 2: The phase of a periodic phenomenon can also be expressed or specified by angular measure, with one period usually encompassing 360° (2 radians). Note 3: Phase may be represented (a) in polar coordinates by M , where M is the magnitude and is the phase angle, and (b) in Cartesian coordinates, i.e. , an Argand diagram, as (a + jb ), where a is a real component and b is an imaginary component such that tan = (b /a ), where is the phase angle, and the magnitude, M , is (a ² + b ²)^½ 2. A distinguishable state of a phenomenon. (188 ) 3. That period of time during which a specified function occurs in a sequential list of functions. (188 )

Phase
A time based relationship between a periodic function and a reference. In electricity, it is expressed in angular degrees to describe the voltage or current relationship of two alternating waveforms.

phase (in phase; out of phase; wave phase)
1.A phase is a part of a sample of matter that is in contact with other parts but is separate from them. Properties within a phase are homogeneous (uniform). For example, oil and vinegar salad dressing contains two phases: an oil-rich liquid, and a vinegar-rich liquid. Shaking the bottle breaks the phases up into tiny droplets, but there are still two distinct phases. 2. In wave motion, phase is the fraction of a complete cycle that has passed a fixed point since the current cycle began. The phase is often expressed as an angle, since a full cycle is 360^deg; (2). Two waves are "in phase" if the peaks of one wave align with the peaks of the other; they are "out of phase" if the peaks of one wave align with the troughs of the other.

Stationary phase
The immobile phase involved in the chromatographic process. The stationary phase in liquid chromatography can be a solid, a bonded or coated phase on a solid Suppon, or a wall-coated phase. The stationary phase used often characterizes the LC mode. For example silica gel is used in adsorption chromatography, an octa-decyl-silane bonded phase in reversed-phase chromatography, etc.

Phase
("In-phase/Out-of-phase") Actually refers to the polarity of an electrical or acoustic signal. If two or more signals or devices are "out-of-phase" with respect to each other, cancellation or other disturbance of the combined output can result. Some examples of operating phase (polarity) definitions: "Positive sound pressure causes positive output" (microphones) or "positive input causes positive acoustic output" (speakers).

phase
a physically homogeneous part of a material system.

PHASE
(Chemistry) Any of the forms or states, solid, liquid, gas, or Plasma, in which matter can exist, depending on temperature and pressure; a discrete homogeneous part of a material system that is mechanically separable from the rest, as is ice from water.

phase
A major part of a training course that contains one or more modules.
