In computer science, mutual exclusion is a property of concurrency control, which is instituted for the purpose of preventing race conditions. It is the requirement that one thread of execution never enters a critical section while a concurrent thread of execution is already accessing said critical section, which refers to an interval of time ...
Dekker's algorithm is the first known correct solution to the mutual exclusion problem in concurrent programming where processes only communicate via shared memory. The solution is attributed to Dutch mathematician Th. J. Dekker by Edsger W. Dijkstra in an unpublished paper on sequential process descriptions [1] and his manuscript on cooperating sequential processes. [2]
A critical section is a piece of a program that requires mutual exclusion of access. Locks and critical sections in multiple threads As shown in the figure, [ 3 ] in the case of mutual exclusion ( mutex ), one thread blocks a critical section by using locking techniques when it needs to access the shared resource, and other threads must wait ...
The rule of mutual exclusion in molecular spectroscopy relates the observation of molecular vibrations to molecular symmetry. It states that no normal modes can be both Infrared and Raman active in a molecule that possesses a center of symmetry .
Maekawa's algorithm is an algorithm for mutual exclusion on a distributed system. The basis of this algorithm is a quorum -like approach where any one site needs only to seek permissions from a subset of other sites.
The WHO Model List of Essential Medicines (aka Essential Medicines List or EML [1]), published by the World Health Organization (WHO), contains the medications considered to be most effective and safe to meet the most important needs in a health system. [2]
In logic, two propositions and are mutually exclusive if it is not logically possible for them to be true at the same time; that is, () is a tautology. To say that more than two propositions are mutually exclusive, depending on the context, means either 1. "() () is a tautology" (it is not logically possible for more than one proposition to be true) or 2. "() is a tautology" (it is not ...
Mutual Pharmaceutical Co. v. Bartlett, 570 U.S. 472 (2013), is a decision by the Supreme Court of the United States holding that generic drug manufactures cannot be held liable under state law for not adequately labeling medication when federal law prohibits them from changing the label from the original brand name drug.
