  2. Coalescence (physics) - Wikipedia

    en.wikipedia.org/wiki/Coalescence_(physics)

    Representation of the coalescence of two droplets, bubbles, or particles to form a single entity. Coalescence is the process by which two or more droplets, bubbles, or particles merge during contact to form a single daughter droplet, bubble, or particle.

  3. Coalescer - Wikipedia

    en.wikipedia.org/wiki/Coalescer

    A coalescer is a device which induces coalescence in a medium. They are primarily used to separate emulsions into their components via various processes, operating in reverse to an emulsifier.

  4. Apple Partition Map - Wikipedia

    en.wikipedia.org/wiki/Apple_Partition_Map

    Classic Mac OS drivers partition Apple_HFS: Hierarchical File System: Apple_HFS: While normally a HFS or HFS+ volume for Mac OS and Mac OS X, it can also contain an MS-DOS formatted file system (File Allocation Table, which can be accessed by Mac OS and Mac OS X). Apple_HFSX: HFS Plus: This partition contains a HFS+ volume without a HFS wrapper.

  5. Multispecies coalescent process - Wikipedia

    en.wikipedia.org/wiki/Multispecies_coalescent...

    In the type 1 tree the alleles in species A and B coalesce after the speciation event that separated the A-B lineage from the C lineage. In the type 2 tree the alleles in species A and B coalesce before the speciation event that separated the A-B lineage from the C lineage (in other words, the type 2 tree is a deep coalescence tree). The type 1 ...

  6. Coalescent theory - Wikipedia

    en.wikipedia.org/wiki/Coalescent_theory

    Coalescent theory is a model of how alleles sampled from a population may have originated from a common ancestor.In the simplest case, coalescent theory assumes no recombination, no natural selection, and no gene flow or population structure, meaning that each variant is equally likely to have been passed from one generation to the next.

  7. Multiply–accumulate operation - Wikipedia

    en.wikipedia.org/wiki/Multiply–accumulate...

    The hardware unit that performs the operation is known as a multiplier–accumulator (MAC unit); the operation itself is also often called a MAC or a MAD operation. The MAC operation modifies an accumulator a : a ← a + ( b × c ) {\displaystyle a\gets a+(b\times c)}

  8. Coalescence - Wikipedia

    en.wikipedia.org/wiki/Coalescence

    COALESCE, an SQL function that selects the first non-null from a range of values; Null coalescing operator, a binary operator that is part of the syntax for a basic conditional expression in several programming languages; Coalesced hashing, a strategy of hash collision resolution in computing

  9. Microvoid coalescence - Wikipedia

    en.wikipedia.org/wiki/Microvoid_coalescence

    SEM image of microvoid coalescence seen on a ductile fracture surface of 6061-T6 Al. Microvoid coalescence (MVC) is a high energy microscopic fracture mechanism observed in the majority of metallic alloys and in some engineering plastics.
