When an executing unit ( process or thread ) receives a signal from the OS, it should react in some way defined by the datasheet and the conventional meaning of this signal ( i. e. by dumping its data, stopping execution, synchronizing something ...).

When the kumquats are divided into multiple species the name Fortunella japonica ( Citrus japonica ) is retained by this group.

When the kumquats are divided into multiple species the name Fortunella obovata ( Citrus obovata ) is used for this group.

When adding, subtracting, or comparing vulgar fractions, it is useful to find the least common multiple of the denominators, often called the lowest common denominator, because each of the fractions can be expressed as a fraction with this denominator.

When a program comprises multiple object files, the linker combines these files into a unified executable program, resolving the symbols as it goes along.

When considering a new application, the engineer can compare multiple learning algorithms and experimentally determine which one works best on the problem at hand ( see cross validation.

When multiple parties want the same thing, pit them against one another.

When optic neuritis is associated with MRI lesions suggestive of multiple sclerosis ( MS ) then general immunosuppressive therapy for MS is often prescribed ( IV methylprednisolone may shorten attacks ).

A number a is a root of P if and only if the polynomial x − a ( of degree one in x ) divides P. It may happen that x − a divides P more than once: if ( x − a )< sup > 2 </ sup > divides P then a is called a multiple root of P, and otherwise a is called a simple root of P. If P is a nonzero polynomial, there is a highest power m such that ( x − a )< sup > m </ sup > divides P, which is called the multiplicity of the root a in P. When P is the zero polynomial, the corresponding polynomial equation is trivial, and this case is usually excluded when considering roots: with the above definitions every number would be a root of the zero polynomial, with undefined ( or infinite ) multiplicity.

When these viral episomes initiate lytic replication to generate multiple virus particles, they in general activate cellular innate immunity defense mechanisms that kill the host cell.

When multiple routers are used in interconnected networks, the routers exchange information about destination addresses, using a dynamic routing protocol.

When spasticity occurs, such as following a stroke, it manifests in abnormal and stereotypical patterns across multiple joints called obligatory synergies.

When action potentials from multiple presynaptic neurons fire simultaneously, or if a single presynaptic neuron fires at a high enough frequency, the EPSPs can overlap and summate.

When user's requests for multiple programs are conflicting, the lower priority program in the Season Pass Manager is either not recorded or clipped where times overlap.

When the researchers did the experiment multiple times, they found that measurement of one polarization did not always disturb the other state as much as the uncertainty principle predicted.

When a cartridge was inserted into the system, the 7800 BIOS included code which would generate a digital signature of the cartridge ROM and compare it to the signature stored on the cartridge.

When the original digital signature generating software was turned over to the Atari community, development of new Atari 7800 titles began.

When information is stored in digital systems, collation may become an automated process.

* Granularity: When a continuously variable analog value is represented in digital form there is always a decision as to the number of symbols to be assigned to that value.

When all of the sound, picture, and data elements of a production have been completed, they may be assembled into a Digital Cinema Distribution Master ( DCDM ) which contains all of the digital material needed for projection.

When playing live, Lee and his bandmates recreate their songs as accurately as possible with digital samplers.

When a note is played on a MIDI instrument, it generates a digital signal that can be used to trigger a note on another instrument.

When placed on the external address bus, it replicates the original functions of B and C. Port A has input capture, output compare, pulse accumulator, and other timer functions ; port D has serial I / O, and port E has an analog to digital converter ( ADC ).

When the first modern digital computers appeared in the early 1940s, the instructions to make them operate were wired into the machine.

When logic analyzers first came into use, it was common to attach several hundred " clips " to a digital system.

When the voltages are nearly equal, the output voltage will not fall into one of the logic levels, thus analog signals will enter the digital domain with unpredictable results.

When digital circuits switch state, large current pulses flow from the integrated circuits through the ground circuit.

When first proposed, no one had built a digital computer that would fit in a missile.

When RealAudio was introduced, RealNetworks disclosed no technical details about the audio format or how it was encoded, but it was soon noticed that some of the audio codecs used in RealAudio were identical to those used in cellular telephones and digital television.

When ownership of a digital signature secret key is bound to a specific user, a valid signature shows that the message was sent by that user.

When a unit is activated with a subscription, an authorization code is sent in the digital stream telling the receiver to allow access to the blocked channels.

When U. S. telephone systems became digital in the 1960s, they used an 8-bit data sample size to digitize voice.

When seen through a digital camera, the diode appears to illuminate purple light.

When animating in a digital context, especially with Adobe Flash, the shortened term tweening is commonly used.
