Negative of → completeness.

1) Lack of consistency or agreement; incompatibility; an inconsistent feature or quality.
2) Logic: The property of being inconsistent; a self-contradictory proposition (TheFreeDictionary.com).

→ in-; → consistency.

1) Lacking in consistency, agreement, or compatibility; at variance.
2) Containing contradictory elements.
4) Maths: (of two or more equations) not having one common set of values of the variables: x + 2y = 5 and x + 2y = 6 are inconsistent
5) Logic: (of a set of propositions) Enabling an explicit contradiction to be validly derived (TheFreeDictionary.com).

→ in-; → consistent.

The → negative of the → logarithm of the → probability that a particular → message or → symbol will be emitted by a → source.

→ information; → content.

The act or fact of insisting; the quality of being insistent.

Verbal noun of → insist.

Earnest or emphatic in dwelling upon, maintaining, or demanding something; persistent; pertinacious (Dictionary.com).

Adjective from → insist.

Existing or occurring in a high or extreme degree. See also → tense.

From M.Fr. intense, from L. intensus "stretched, strained, tight," originally p.p. of intendere "to stretch out, strain," from in- "toward" + tendere "to stretch;" from PIE base *ten- "to stretch;" cf. Pers. tanidan "to spin, twist, weave," as below.

âtanu, from â- affirmative prefix + tanu "stretched, strained," from tan + -u suffix of excess. The middle element tan, from tanidan "to spin, twist, weave" (Mid.Pers. tanitan; Av. tan- to stretch, extend;" cf. Skt. tan- to spin, stretch;" tanoti "stretches," tantram "loom;" Gk. teinein "to stretch, pull tight;" L. tendere "to stretch;" PIE base *ten- "to stretch"), Pers. târ "string," tân "thread," tur "fishing net, net, snare," and tâl "thread" (Borujerdi dialect) belong to this family; variants tanta "cobweb," tanadu, tafen, kartané, kârtané, kâtené, Pashtu tanistah "cobweb;" cf. Skt. tantu- "cobweb, thread, string").

The action of making or becoming stronger or more extreme.

verbal noun of → intensify.

1) Something that intensifies.
2) Substance used to increase the density or contrast of an image on a photographic film or plate.

Agent noun of → intensify.

To make intense or more intense.
To increase the density and contrast of a photographic image by chemical treatment.

From → intense + -ify variant of -fy after a consonant, from O.Fr. fier, from L. -ficare "to do, make."

General: The quality or condition of being intense.
Physics: Strength, as of energy or a force per unit of area, solid angle, time, etc.; e.g. → electric intensity; → magnetic intensity.

From → intense + → -ity.

Dartanuyi state, condition noun of dartanu, → intense.

The height of a spectral line above the continuum base.

→ intensity; → line.

The rate of emitted energy from unit surface area through unit solid angle. The radiation from a surface has different intensities in different directions.

→ intensity; → radiation.

1) Of, pertaining to, or characterized by intensity.
2) Tending to intensify; intensifying.
3) Requiring or having a high concentration of a specified quality or element (used in combination).
4) Grammar: Indicating increased emphasis or force. "Certainly" is an intensive adverb. "Myself," in I did it myself, is an intensive pronoun (Dictionary.com).

→ intense; → -ive.

A prefix that highly emphasizes roots of words to which it is attached. In other words, intensive prefixes heighten the force of the primary meanings of words. These prefixes can effectively be translated as "thoroughly" to highlight their intensive function. For example the prefixes → re-, → de-, and → com-.

→ intensive; → prefix.

A property of a turbulent dynamical system which is characterized by chaotic, irregular behavior occurring between quiet (or less irregular) periods. In other words, a → turbulent flow having a large → Reynolds number undergoes a phenomenon in which its turbulent activity at a fixed location stops from time to time and starts again. In fact → turbulence never completely disappears, but it can become extremely weak interrupted irregularly by bursts of strong turbulence (see also → developed turbulence). For intermittent flows → probability density functions are not → Gaussian. Turbulent intermittency plays a fundamental role in fields ranging from combustion physics, chemical engineering, meteorology, to astrophysical systems, more specifically the → interstellar medium.

From L. intermittent, pr.p. of intermittere "to leave a space between, drop (for a while), leave off," from → inter- + mittere "to send, let go."

Raftomând, literally "to go and to stop," from raft past stem of raftan "to go, walk, proceed" (present stem row-); Mid.Pers. raftan, raw-, Proto-Iranian *rab/f- "to go; to attack") + -o- euphonic infix + mând past stem of mândan "to remain, stay, relinquish, leave" (Mid.Pers. mândan "to remain, stay," mân "house, home;" O.Pers. mān- "to remain, dwell;" Av. man- "to remain, dwell; to wait;" cf. Gk. menein "to remain;" L. manere "to stay, remain, abide," mansio "a staying, a remaining, night quarters, station" (Fr. maison, ménage; E. manor, mansion, permanent; PIE *men- "to remain, wait for").

Alternately ceasing and beginning again; adj. of → intermittency.

Adjective of → intermittency.

A unidirectional electric current that flows and ceases to flow at irregular or regular intervals.

→ intermittent; → current.

The energy required to remove an electron from an isolated atom or molecule. The ionization potential for hydrogen is 13.6 eV, which corresponds to an ultraviolet ionizing photon with a wavelength of 912 A. Also called → ionization energy.

→ ionization; → potential.

Same as → Lagrangian function.

→ kinetic; → potential.
