2. Vacancy defect - Wikipedia

   en.wikipedia.org/wiki/Vacancy_defect

   In crystallography, a vacancy is a type of point defect in a crystal where an atom is missing from one of the lattice sites. [2] Crystals inherently possess imperfections, sometimes referred to as crystallographic defects. Vacancies occur naturally in all crystalline materials. At any given temperature, up to the melting point of the material ...

3. M/M/c queue - Wikipedia

   en.wikipedia.org/wiki/M/M/c_queue

   In the M/M/c queue this means that when there are c or fewer jobs in the system, each job is serviced at rate μ. However, when there are more than c jobs in the system the service rate of each job decreases and is where n is the number of jobs in the system. This means that arrivals after a job of interest can impact the service time of the ...

5. Nitrogen-vacancy center - Wikipedia

   en.wikipedia.org/wiki/Nitrogen-vacancy_center

   As in NV 0, the vacancy electrons are "exchanging roles" preserving the overall trigonal symmetry. This NV − state is what is commonly, and somewhat incorrectly, called "the nitrogen-vacancy center". The neutral state is not generally used for quantum technology. The NV centers are randomly oriented within a diamond crystal.

6. Beveridge curve - Wikipedia

   en.wikipedia.org/wiki/Beveridge_curve

   Beveridge curve. A Beveridge curve, or UV curve, is a graphical representation of the relationship between unemployment and the job vacancy rate, the number of unfilled jobs expressed as a proportion of the labour force. It typically has vacancies on the vertical axis and unemployment on the horizontal. The curve, named after William Beveridge ...

7. M/G/1 queue - Wikipedia

   en.wikipedia.org/wiki/M/G/1_queue

   M/G/1 queue. In queueing theory, a discipline within the mathematical theory of probability, an M/G/1 queue is a queue model where arrivals are M arkovian (modulated by a Poisson process ), service times have a G eneral distribution and there is a single server. [1] The model name is written in Kendall's notation, and is an extension of the M/M ...
