System in which energy but not matter is exchanged between the system and its environment. Compare open system.
A system that is cut off from its environment and does not interact with it. See also Open system.
n. A system whose characteristics comply with proprietary standards and that therefore cannot readily be connected to other systems.
a clearly defined whole - for example, a business building or a hospital
a contradiction of terms, as any system by definition has an inside and an outside, and cannot close itself off completely from interchange with the universe around it
an environment in which no information, matter or energy can be added or removed from beyond its boundaries
an ideal system, one without outside influence, which is absolutely impossible in the layers of rock in our planet
a recirculation loop for water (or other liquid) where once it is set up and running, no new liquid is introduced into the system
a self contained system that does not interacts/exchange across its boundaries with its environment by virtue of which it cannot obtain any feedback and tend to detervuate
a system that does not interact in any way with its surroundings
a system to and from which no energy (especially heat) or matter (atoms and molecules, etc
a system where no energy leaves the system and goes into the outside world, and no energy from the outside world enters the system
a system where only energy is transferred or exchanged with its surroundings
a system where there is no interchange of particles between the reacting mixture and the outside environment
a system which is completely isolated from its surroundings
Describes a way of using an operating system characterized by knowledge of the set of applications that will be run, and their relative importances. This permits a priori schedulability analysis.
a hydroponic system in which the nutrient solution is collected, usually in a cistern, and then circulated through the system many times
a system that does not exchange matter with the surroundings
a system that has little or no links to its external environment.
A contained system; the belayer tying in to the end of the rope forms a "closed system" that will keep the climber from being dropped; the magic X forms a "closed system" wherein the master point is attached to the sling and not merely looped over it
is a type of system which is self-contained, not having inputs and not producing outputs
a hydroponic system, like nutrient film technique (NFT) systems, that recirculates the nutrient solution.
System wherein white water or filtrate is mainly recirculated and not discharged to waste.
Is is a system that transfers energy, but not matter, across its boundary to the surrounding environment. Our planet is often viewed as a closed system.
A system that monitors your entrance and exit and calculates the toll on the basis of distance traveled.
1. In mathematics, a system of differential equations and supplementary conditions such that the values of all the unknowns ( dependent variables) of the system are mathematically determined for all values of the independent variables (usually space and time) to which the system applies. 2. In thermodynamics, a system of fixed mass. By some definitions such a system may be confined to an impermeable container. An idealized air parcel, not diffusing into or mixing with its environment and undergoing a saturation- adiabatic process, is closed, as contrasted to one undergoing pseudoadiabatic expansion with precipitation removed. Compare open system, isolated system. 3. In synoptic meteorology, loosely used for a closed low or closed high.
Breast pumps designed for multiple users, such as hospital grade rental pumps. There is no possibility of breast milk entering the pump motor. See this used breast pumps article for more information. Although the Avent Isis IQ breast pumps are said to be closed system, Avent still recommends their pumps to be single user.
A kind of payment card system in which one organization both issues cards and acquires merchants. American Express, Diners Club, and Discover are examples of closed systems.
A system where the incoming cold water supply has a device that will not allow water to expand when heated. (i.e. check valve, backflow preventer, pressure reducing valve, etc.)
A closed system is a system which relies on a feedback loop to control its output in a control system in systems theory. (It is sometimes called "closed-loop system.") The system is a "closed" system because it is closed by a feedback loop in its control, as opposed to an open system where there is no feedback loop in its system.
