A specific part of an instruction word in some binary computers, thus a set of digits.
For a counter, to subtract 1 or some other number from the current value.
The quantity by which a variable is decreased.
The ratio of the amplitudes of an underdamped harmonic motion during two successive oscillations. Also known as damping factor; numerical decrement.



the weakening of an excitation according to the extent of its distribution along a nerve or muscle fiber.

In normal nerve and skeletal-muscle (striated) fibers of vertebrate animals, an excitation or, specifically, its electrical component—the activity potential—conforms to the so-called all-or-none rule—that is, it arises only after the stimulus attains threshold intensity; once it arises, it is distributed further without decrement. In certain tissues (for example, in many arthropod muscles) excitation is distributed with decrement even under normal conditions. According to the membrane theory of excitation, nondecremental conduction of excitation is converted to decremental conduction in all cases when there is a decrease in regenerative depolarization, which is basic for the formation of the activity potential. This takes place, for example, when a nerve or muscle is under the influence of anesthetics or narcotics and when there is cessation of blood circulation.

To subtract a number from another number. Decrementing a counter means to subtract 1 or some other number from its current value.

Obtained decrements of all desired modes are presented in Table 3, where damping decrements of another glider--LAK-17A are presented for comparison too.
6) for the well-being sub-scale, indicating more decrements in physical health than well-being.
t](S) are weighted with the number of decrements due to death and surrender, respectively, at the time of the decrement given in Part (b) of Figure 1.
Vibration damping of composite ligno-cellulose plates is the phenomenon that occurs as a result of sound losses of sound energy dissipated in the material being an interdependent phenomenon of internal friction (expressed as logarithmic decrement of vibrations damping), the contributions of constituents, their combination of architecture and the stages between phases (Alamoreanu, 2005).
In many instances, the decrement will result in higher taxable income to the taxpayer.
They describe hard and soft excitations in transitions, converting propellant to combustion products, testing at various stages of combustor development, and studying acoustics in combustion chamber stability, natural disturbances, artificial pressure disturbances, injector head elements, pressure oscillation decrements, pulsing liquid-liquid chambers, and gas-liquid chambers.
Similarly, in ASPD patients, previous P300 ERP studies have revealed decrements in frontal brain structure and function.
Impairments in simulated driving are evident even at relatively modest blood alcohol levels, and wakefulness, prolonged by even 3 hours, can produce decrements in the ability to maintain speed and road position as serious as those found at the legal limits of alcohol consumption.
What is often missing is information that would link diagnosis and treatment with health outcomes that are fully meaningful to the patient's life, namely information about the presence of decrements in capacity to carry out tasks and actions in areas of life as well as how these decrements play out in the person's actual, real-life environment (Deyo and Patrick, 1989; Lubetkin et al.
Log decrements were determined from the time-amplitude response decay curve for free vibration and from the frequency-amplitude response curve for forced vibration.
Therefore, it is important to detect decrements in goal-specific and domain-specific hope early in order to aid students in developing strategies (pathways) and confidence (agency) regarding the pursuit of appropriate goals.
One of the newest and freshest ideas in the field is "universal design"--an approach to making older people's dwellings habit able for them for as long as possible, regardless of the decrements of aging.
