If the pencil with the angle u2 is that of the maximum aberration of all the pencils transmitted, then in a plane perpendicular to the axis at O ' 1 there is a circular disk of confusion of radius O ' 1R, and in a parallel plane at O ' 2 another one of radius O ' 2R2 ; between these two is situated the disk of least confusion.

If a DFS ROM is installed, will cause the computer to search for and load a file called on the floppy disk in drive 0.

If the disk was not otherwise prepared with a custom format, ( e. g. for data disks ), 664 blocks would be free after formatting, giving 664 × 254 = 168, 656 bytes ( or almost 165 kB ) for user data.

If the missile starts to roll, the gyroscopic force of the disk drives the control surface into the airflow, cancelling the motion.

If these relations are stored physically as separate disk files, completing a database query that draws information from several relations ( a join operation ) can be slow.

: If a planet crosses ( or transits ) in front of its parent star's disk, then the observed brightness of the star drops by a small amount.

If a piece of data is not retrieved for some time and a node keeps getting new data, it will drop the old data sometime when its allocated disk space is fully used.

If there is a difference in velocity between two disks, any matter transferred between them must be accelerated by the disk accordingly.

If the rotor disk is to be tilted forward ( to gain forward velocity ), its rotation requires that the downward net force on the blade be applied roughly 90 degrees ( depending on blade configuration ) before, or when the blade is to one side of the pilot and rotating forward.

If two devices overwrote the same memory location in a conflict, and the hard disk controller relied on this location ( the HDD controller often being the 2nd conflicting device ) there was the all-too-common possibility of massive data corruption.

If a connection delay of a minute or two is acceptable, the machine can timeout into hibernation, powered off with its state saved to disk.

If an external disk drive was added, the "+ 2A " on the system OS menu would change to a + 3.

The first stage of boot loaders located on fixed disks and removable drives must fit into the first 446 bytes of the Master Boot Record in order to leave room for the default 64-byte partition table with four partition entries and the two-byte boot signature, which the BIOS requires for a proper boot loader — or even less, when additional features like more than four partition entries ( up to 16 with 16 bytes each ), a disk signature ( 6 bytes ), a disk timestamp ( 6 bytes ), an Advanced Active Partition ( 18 bytes ) or special multi-boot loaders If an active partition is found, the MBR code loads the boot sector code from that partition, known as Volume Boot Record ( VBR ), and executes it.

If a user changed disks without manually rereading the disk directory the system would write on the new disk using the old disk's directory information, ruining the data stored on the disk.

If the visible disk of the nearer object is considerably smaller than that of the farther object, the event is called a transit.

If there is only one disk ( or even none at all ), the problem is trivial.

If h = 1, then simply move the disk from peg A to peg C. If h > 1, then somewhere along the sequence of moves, the largest disk must be moved from peg A to another peg, preferably to peg C. The only situation that allows this move is when all smaller h-1 disks are on peg B.

If the galaxies are of similar size, the resultant galaxy will appear similar to neither of the two galaxies merging, but would instead be an elliptical galaxy.

If the two galaxies do meet they will pass through each other, with gravity distorting both galaxies severely and ejecting some gas, dust and stars into intergalactic space.

If there is insufficient kinetic energy, however, the group may evolve into a smaller number of galaxies through mergers.

If one divides a change in proper distance by the interval of cosmological time where the change was measured ( or takes the derivative of proper distance with respect to cosmological time ) and calls this a " velocity ", then the resulting " velocities " of galaxies or quasars can be above the speed of light, c. This apparent superluminal expansion is not in conflict with special or general relativity, and is a consequence of the particular definitions used in cosmology.

If disc galaxies had mass distributions which were similar to the observed distribution of stars and gas, the rotation curves velocities should decline at large distances ( dotted line A in illustration ), in the same way as other systems with most of their mass in the centre, such as the Solar System of planets or the moons of Jupiter, following the prediction of Kepler's Laws.

If masses of galaxies are derived solely from the luminosities and the mass-to-light ratios in the disk and core portions of spiral galaxies are assumed to be close to that of stars, the masses derived from the kinematics of the observed rotation and the law of gravity do not match.

If this is the case, there must be a population of objects not beamed towards us, and, since we know the lobes are not affected by beaming, they would appear as radio galaxies, provided that the quasar nucleus is obscured when the source is seen side-on.

If lenticular galaxies are an evolved stage of spiral galaxies then they should have a similar Tully-Fisher relation with spirals, but with an offset in the luminosity / absolute magnitude axis.

If our universe is approaching a de Sitter universe then eventually we will not be able to observe any galaxies other than our own Milky Way ( and any others in the gravitationally bound Local Group, assuming they were to somehow survive to that time without merging ).

If this hypothesis is correct, dwarf galaxies may be the building blocks of today's giant galaxies.

If this happens that would increase the density at the center of a galaxy, and thus make a bulge that has properties similar to disk galaxies.

If secular evolution, or the slow, steady evolution of a galaxy, is responsible for the formation of a significant number of bulges, then that many galaxies have not experienced a merger since the formation of their disk.

If tired light was a correct explanation, these galaxies would appear blurred in comparison to closer galaxies.

If he looks into the oncoming wavefronts at distant galaxies which have already encountered the wave, he will see their images undistorted.

If a nearby cluster of galaxies is used to calibrate the Tully-Fisher relation, and then that relation is applied to a distant cluster, the distance to the farther cluster will be systematically underestimated.

If this is the case, it would provide an excellent illustration of the distortion caused by interacting galaxies, discussed in the article Galaxy formation and evolution under the Spiral galaxy heading.

If resolved into stars they might be the first galaxies to be identified as such.

If placing a tile causes three or four chains to merge, then the merger steps are handled between the largest and second-largest chain, then with the third-largest chain, and finally with the smallest chain.

If there are two horizons there is side error ; adjust the horizon glass / mirror until the stars merge into one image or the horizons are merged into one.

If one is above the other adjust the index mirror until the two horizons merge.

If a previous sound change causes X, Y > Y ( features X and Y merge as Y ), a new one cannot affect only original X's.

* If a tribe prior to the merge is down to two players, as in Palau, those two will also face off in a challenge to determine who is to leave the game.

If you have an external hard drive that serves as a backup of your music then manually updating the music, even when copies merge directories, can be an error prone and time consuming task best left to automation.

If two penumbras overlap, the shadows appear to attract and merge.

If two businesses merge, their identities merge.

If chosen, the U. S. Government, in an unprecedented move, offered to merge the U. S. AMRAAM and UK BVRAAM programmes, under joint control.

Explaining where such a policy could be headed, he added: " If Dodik manages to merge Republika Srpska with Serbia, all Croats concentrated in Herzegovina will want to join Croatia in the same manner, leaving a rump Bosniak country, surrounded by enemies.

If, in this transit, it meets with sperm, the sperm penetrate and merge with the egg, fertilizing it.

If there is also a meld or merge operation that can create a new version from two previous versions, the data structure is called confluently persistent.

If the system cannot complete the merge then the commit will be rejected.

If a merge cannot be resolved by the revision control software it is up to the user to merge the changes.

If the two states did merge at certain times, Alodia regained its independence.

If one of the potential merges is deemed a valid merge, the zones are then merged.

If the merge is successful, routing tables of neighboring zones ' nodes are updated to reflect the merge.

## If v < sub > 1 </ sub > is not adjacent to v < sub > 3 </ sub >, we can merge these two vertices into a single vertex.

If we merge into a single factor, the resulting factor graph will be a tree.

If two networks meet, and decide to merge, a new ACS will be formed of the two ( though the two networks will have their own ACS along with the interfaces inside this global, new ACS ).
