When an alphabet is adopted or developed for use in representing a given language, an orthography generally comes into being, providing rules for the spelling of words in that language.

When numbers are used to represent months, a significant amount of confusion can arise from the ambiguity of a date order ; especially when the numbers representing the day, month or year are low, it can be impossible to tell which order is being used.

When necessary, vowels are indicated by diacritic marks above or below the letter representing the syllabic onset, or by use of matres lectionis, which are consonantal letters used as vowels.

When performed ' in token ' this involves the athame ( representing the masculine principle ) descending into the chalice ( representing the feminine ).

When an alphabet is borrowed to represent a different language than that for which it originally developed ( as has been done with the Latin alphabet for many languages in Europe and elsewhere or Japanese Katakana being used for foreign words ), it often proves to be defective in representing the new language's phonemes.

When Gérôme exhibited For Sale ; Slaves at Cairo at the Royal Academy in London in 1871, it was " widely found offensive ", perhaps partly because the British liked to think they had successfully suppressed the slave trade in Egypt, also for cruelty and " representing fleshiness for its own sake ".

When elements representing two factors are required for identification, the term two-factor authentication is applied — e. g. a bankcard ( something the user has ) and a PIN ( something the user knows ).

When a pawn makes a capture, the file from which the pawn departed is used to identify the pawn, rather than a letter representing the pawn itself.

When representing source code in Lisp, the first element of an S-expression is commonly an operator or function name and any remaining elements are treated as arguments.

When a new town was founded, a round hole would be dug and a stone called a lapis manalis would be placed in the foundations, representing a gate to the underworld.

When the first charter of the town was secured by an attorney representing the railroad ( Middleton P. Barrow ), the name was changed to Cornelia in honor of his second wife ( and daughter of Confederate Major General Henry R. Jackson ), and so it has remained.

When an expression of the form is evaluated, a special " continuation " object is constructed, representing the state of the interpreter at that moment.

When this has been accomplished, a title representing the player's overall progress in the game is awarded.

When several rings or circles were combined representing the great circles of the heavens, the instrument became an armillary sphere.

When the top bit was made available for representing character data, a total of 256 characters and control codes could be represented.

When Sal Paradise visits Old Bull Lee in the novel ( characters representing Kerouac and Burroughs, respectively ), Lee's orgone accumulator is described as follows:

When the incident beam is represented by a quantum pure state, the split beams downstream of the two slits are represented as a superposition of the pure states representing each split beam.

When King Louis XIV of France wanted to instruct his six-year-old son, he incorporated the series of hydraulic statues representing 38 chosen fables in the labyrinth of Versailles in the 1670s.

When people are asked to invent data representing 200 coin tosses, they often do not add streaks of more than 5 because they believe that these streaks are very unlikely.

When he took his GCB he had as supporters on his coat of arms a private of the Rifle Brigade and a female figure representing Ulster.

When the coalition was re-formed under Kerensky on July 24, Nekrasov remained deputy prime minister and also became finance minister, representing the Radical-Democratic Party.

When parliament assembled Parkes was elected leader of the opposition, representing East Sydney.

When Tynwald meets annually ( normally on 5 July ) at an open air ceremony at Tynwald Hill at St John's, the Lieutenant Governor of the Isle of Man presides, unless HM The Queen as Lord of Mann, or a member of the Royal Family representing Her Majesty, is present.

When the Hebrews came to the outskirts of Canaan, the land that had been promised to them by God, after having fled slavery in Egypt, Moses ( the Hebrew leader ) sent twelve spies (, meraglim ) into Canaan to report on what was there — one spy representing each of the Twelve Tribes.

When a group of different plant species was prompted by a variety of different stress signals, such as drought or cold, each plant responded uniquely.

When large numbers of delayed signals are mixed over several seconds, the resulting sound has the effect of being presented in a large room, and it is more commonly called reverberation or reverb for short.

The monochrome combinations still existing in the 1950s are standardized by the International Telecommunication Union ( ITU ) as capital letters A through N. When color television was introduced, the hue and saturation information was added to the monochrome signals in a way that black & white televisions ignore.

When analog television was developed, no affordable technology for storing any video signals existed ; the luminance signal has to be generated and transmitted at the same time at which it is displayed on the CRT.

Neurons generate electrical signals that travel along their axon s. When a pulse of electricity reaches a junction called a synapse, it causes a neurotransmitter chemical to be released, which binds to receptors on other cells and thereby alters their electrical activity.

When the myelin sheath is damaged, nerve signals are slower, and this can be measured by a common neurological test, electromyography.

When two stations transmit at the same phase-locked frequency, the difference in phase between the two signals is constant along a hyperbolic path.

When animals or people free-run, experiments can be done to see what sort of signals, known as zeitgebers, are effective in entrainment.

When the actuator reaches the desired position, the two signals ( incoming and outgoing ) cancel each other out and the actuator stops moving ( completing a feedback loop ).

When processing signals, such as audio, radio waves, light waves, seismic waves, and even images, Fourier analysis can isolate individual components of a compound waveform, concentrating them for easier detection and / or removal.

When myelin degrades, conduction of signals along the nerve can be impaired or lost and the nerve eventually withers.

When the row was activated, it would activate the control signals connected to it.

When GPIO pins are configured to an input state, they are often used to read sensors or external signals.

When myelin degrades, conduction of signals along the nerve can be impaired or lost, and the nerve eventually withers.

When nociceptors are stimulated they transmit signals through sensory neurons in the spinal cord.

When the water level is below both switches, the switch contacts are closed providing signals to both the " Low Level " and " High Level " inputs to the PLC.

When the bladder is stretched, this signals the parasympathetic nervous system to contract the detrusor muscle.

When not actively in contact with another station, the HF SSB transceiver constantly scans through a list of HF frequencies called channels, listening for any ALE signals transmitted by other radio stations.

When both signals are nearly equal in strength, or are fading independently, the receiver may switch from one to the other and exhibit picket fencing.

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 the two signals are mixed, a " beat " frequency equal to the difference between the two frequencies is created.

When loading coils are in place, signal attenuation remains low for signals within the passband of the transmission line but increases rapidly for frequencies above the audio cutoff frequency.

When voice signals are digitized for transmission via T-carrier, the data stream always includes ample 1 bits to maintain synchronization.

When large numbers of delayed signals are mixed over several seconds, the resulting sound has the effect of being presented in a large room, and it is more commonly called reverberation or reverb for short.

When some repair nerves are prodded by compression or pain to send out their repair signals, a chain reaction spreads out to set other repair nerves in the same meridian into action.
