  2. powercfg - Wikipedia

    en.wikipedia.org/wiki/Powercfg

    powercfg must be run from an elevated command prompt, and, under Windows XP, it requires workstation Administrator or power user rights. Power Schemes are configured on a per-user basis. The most common cause of problems with power saving and hibernation on Windows systems is an incompatible device driver.

  3. Word problem (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Word_problem_(mathematics)

    Note that the rewriting here is one-way. The word problem is the accessibility problem for symmetric rewrite relations, i.e. Thue systems. [27] The accessibility and word problems are undecidable, i.e. there is no general algorithm for solving this problem. [28]

  4. Word problem (mathematics education) - Wikipedia

    en.wikipedia.org/wiki/Word_problem_(mathematics...

    Word problem from the Līlāvatī (12th century), with its English translation and solution. In science education, a word problem is a mathematical exercise (such as in a textbook, worksheet, or exam) where significant background information on the problem is presented in ordinary language rather than in mathematical notation.

  5. Unit commitment problem in electrical power production

    en.wikipedia.org/wiki/Unit_Commitment_Problem_in...

    In a free-market regime, the aim is rather to maximize energy production profits, i.e., the difference between revenues (due to selling energy) and costs (due to producing it). If the GenCo is a price maker, i.e., it has sufficient size to influence market prices, it may in principle perform strategic bidding [12] in order to improve its ...

  6. Power system operations and control - Wikipedia

    en.wikipedia.org/wiki/Power_system_operations...

    Power system operations is a term used in electricity generation to describe the process of decision-making on the timescale from one day (day-ahead operation [1]) to minutes [2] prior to the power delivery.

  7. Word problem for groups - Wikipedia

    en.wikipedia.org/wiki/Word_problem_for_groups

    The word problem was one of the first examples of an unsolvable problem to be found not in mathematical logic or the theory of algorithms, but in one of the central branches of classical mathematics, algebra. As a result of its unsolvability, several other problems in combinatorial group theory have been shown to be unsolvable as well.

  8. Status register - Wikipedia

    en.wikipedia.org/wiki/Status_register

    A status register, flag register, or condition code register (CCR) is a collection of status flag bits for a processor.Examples of such registers include FLAGS register in the x86 architecture, flags in the program status word (PSW) register in the IBM System/360 architecture through z/Architecture, and the application program status register (APSR) in the ARM Cortex-A architecture.

  9. Order of operations - Wikipedia

    en.wikipedia.org/wiki/Order_of_operations

    Order of operations. In mathematics and computer programming, the order of operations is a collection of rules that reflect conventions about which operations to perform first in order to evaluate a given mathematical expression. These rules are formalized with a ranking of the operations.
