  Power set - Wikipedia, the free encyclopedia
The power set of the set of natural numbers for instance can be put in a one-to-one correspondence with the set of real numbers (by identifying an infinite 0-1 sequence with the set of indices where the ones occur).
The power set of a set S, together with the operations of union, intersection and complement forms the prototypical example of a boolean algebra.
The power set of a set S forms an Abelian group when considered with the operation of symmetric difference (with the empty set as its unit and each set being its own inverse) and a commutative semigroup when considered with the operation of intersection.

 The Power Set
The set of permutations with one integer is denumerable by default.
The power permutation is akin to the power set, the big difference is that the power permutation has repeats.
Either the power set of the integers is denumerable, or the process of tabulating and taking the cross sections of a table is not sufficient to establish the Cantorian dichotomy.

 Power set - InfoSearchPoint.com   (Site not responding. Last check: 2007-11-07)
In formal language, the existence of power set of any set is presupposed by the axiom of power set.
Cantor's diagonal argument shows that the power set of an infinite set always has strictly higher cardinality than the set itself (informally the power set must be 'more infinite' than the original set).
The power set of the natural numbers for instance can be put in a one-to-one correspondence with the set of real numbers (by identifying an infinite 0-1 sequence with the set of indices where the ones occur).

 Encyclopedia: Axiom of power set   (Site not responding. Last check: 2007-11-07)
In mathematics, the axiom of power set is one of the Zermelo-Fraenkel axioms of axiomatic set theory.
Given any set A, there is a set B such that, given any set C, C is a member of B if and only if, given any set D, if D is a member of C, then D is a member of A.
The axiom of power set is generally considered uncontroversial, and it or an equivalent appears in just about any alternative axiomatisation of set theory.

 In-line power gear set to grow   (Site not responding. Last check: 2007-11-07)
A proposed standard for powering network devices over Ethernet cabling is still a year from completion, but users of IP telephones and wireless LAN endpoints are adopting the technology in the meantime.
Powering an IP phone or wireless LAN endpoint over a Category 3 or 5 Ethernet cable should help make business IP telephony phone systems more resilient and make it easier to set up an 802.11X LAN, because it eliminates the need to run power and network lines to wireless LAN endpoints, experts say.
Powered devices - such as IP phones - and PSE gear communicate via electrical signals that let the PSE detect if a device that can receive in-line power is attached.

 Welcome to HoopTactics.com
Since Power's initial attack is down the middle, it attacks both sides of the defense simultaneously making defensive help nearly impossible.
In fact, many teams will automatically flow into the "Power" action whenever their initial set offense breaks down, and will even call their power action "Motion." Continuous motion is created when the point guard passes to either wing and screens away.
Since the Power Offense involves continuous screening action on both sides of the court, if any of the defenders get hung up on a single screen it will most certainly result in a wide open shot for the opponent's best shooters.

 Low power set associative cache memory with status inhibit of cache data output - Patent 5682515
Unfortunately, the power savings due to the reduction in power consumption by the disk through use of the cache memory is typically overshadowed by the power consumption of the cache memory itself.
An output inhibiting device is operable to inhibit accessed data from being output from the cache data memory unless the hit indication signal is generated for the accessed tag and the associated status value indicates the valid cache data in the corresponding location in the cache data memory.
Power is conserved by not allowing the cache data RAM 30 to be enabled prior to a hit being determined.

At the beginning of this section, it was pointed out that a set is an unordered collection of elements, that is, a set is determined by its elements and not by any particular order in which the elements are listed.

Wind power accounts for around one percent of global energy supply, but the sector is growing fast as part of the struggle to cut greenhouse gas emissions, which many scientists say cause global warming.
Europe is still the driving force in the wind power industry accounting for two thirds of global installed MW with Germany being the largest market.
But German wind power plant producers have said they are increasingly looking to sell abroad, build future offshore wind sites in Germany or abroad and upgrade existing plants as domestic onshore sites have become limited in recent years.
