Round or cylindrical patterns are simple to produce with a regular crochet hook, but cylindrical knitting requires either a set of circular needles or three to five special double-ended needles.

TV-guides tend to list nightly programs at the previous day, although programming a VCR requires the strict logic of starting the new day at 00: 00 ( to further confuse the issue, VCRs set to the 12-hour clock notation will label this " 12: 00 AM ").

The implementation of a data structure usually requires writing a set of procedures that create and manipulate instances of that structure.

For example, on a set of quaternary ( i. e., 4-ary ) variables, representing the full function requires storing values, the value of the function for each element in the Cartesian product, i. e., each of the 1024 possible combinations for.

More precisely, he showed that a random graph on vertices, formed by choosing independently whether to include each edge with probability has, with probability tending to 1 as goes to infinity, at most cycles of length or less, but has no independent set of size Therefore, removing one vertex from each short cycle leaves a smaller graph with girth greater than in which each color class of a coloring must be small and which therefore requires at least colors in any coloring.

However, the inquest should set out as many of the facts as the public interest requires.

However, the standard definition of libre requires that a work be free from a particular set of permission restrictions ; some works that qualify as libre open access would not qualify as libre ( for example, those with a Creative Commons NonCommercial or NoDerivatives licence term ).

Black-box evaluation requires one to run an NLP system on a given data set and to measure a number of parameters related to the quality of the process ( speed, reliability, resource consumption ) and, most importantly, to the quality of the result ( e. g. the accuracy of data annotation or the fidelity of a translation ).

Syntactic non-standard analysis requires a great deal of care in applying the principle of set formation ( formally known as the axiom of comprehension ) which mathematicians usually take for granted.

Tracing garbage collection cycles are triggered too often if the set of live objects fills most of the available memory ; it requires extra space to be efficient.

As referential transparency requires the same results for a given set of inputs at any point in time, a referentially transparent expression is therefore deterministic.

This is an extra operation and is not needed unless a gun's magazine or action design requires crimped ammunition for safe operation, such as autoloading firearms, where the cycling of the action may push the bullet back in the case, resulting in poor accuracy and increased pressures.

For ideal results, each type of target requires unique terminal bullet performance and therefore a unique bullet design scheme.

Lastly, a bullet which is " overstabilized " will maintain the orientation it was fired at ; a ballistic trajectory requires the gun to be aimed above the target, thus an overstabilized bullet at long range will be pointing upward, even though it is moving downward, resulting in an oblique impact and aerodynamic inefficiency.

However, they take longer to apply, as they must be cleared from the bore of the suppressor to ensure a clear path for the bullet ( grease requires this step as well ).

This requires the bullet from a. 22 Short to travel a short distance before it engages the rifling, which is detrimental to accuracy.

When fighting bad guys, Courageous Cat would use all-purpose Cat Gun or a vast variety of different deus ex machina " trick guns " he pulls out of his cape that ( like Green Arrow's trick arrows ) fire whatever the situation requires like a rope, some water, a parachute, cages, boxing gloves, lightning-like magnetic rays, or even more bizarre ammunition and even the occasional actual bullet ( in case of emergency Courageous also has extra pre-James Bond secret gadgets hidden in his belt buckle and the star emblem on his chest ).

The thin brass case easily seals the chamber, even in low pressure rounds like the. 22 CB, but expanding or upsetting the bullet sufficiently for effective obturation requires sufficient pressure to deform the bullet material.

The look requires the woman to wear a pointed circular stitched conical shape bra, sometimes called a bullet bra, which raises and separates her breasts. In its original form, the look was often tied to the promotion of new bra technology.

These other metals and their alloys can be cold-worked, or melted in simple pottery kilns and cast in molds ; but smelted iron requires hot-working and can be melted only in specially designed furnaces.

Today molding lines can achieve a molding rate of 550 sand molds per hour and requires only one monitoring operator.

It requires less than $ 50 USD in materials to make, and is made of concrete poured into two simple fibreglass molds, some metal parts, one wrench and any piece of rock or wood that might serve as a hammer.

Schweitzer seems, in fact, to acquire for himself a burden of sin, not bequeathed by Adam, but accumulated in the inevitable judgments which life requires of him as between greater and lesser responsibilities.

And to do this requires first of all the kind of information about people which is provided by the scientists in industrial anthropology and consumer research, who, for example, tell Courtenay that three days is the `` optimum priming period for a closed social circuit to be triggered with a catalytic cue-phrase '' -- which means that an effective propaganda technique is to send an idea into circulation and then three days later reinforce or undermine it.

The first possibility requires that there be a line through P which meets **zg in Af points ; ;

the second requires that there be a line through P which meets **zg in Af points.

Destruction of the enemy's building and base complex, however, requires attacks on enemy territory, which is possible only in event of all-out hostilities.

An electrostatic system suffers generally from image plane curvature leading to defocusing in the peripheral image region if a flat viewing screen ( or interstage coupler ) is utilized, while a magnetic system requires accurate adjustment of the solenoid, which is heavy and bulky.

Sir Julian Huxley in his book Uniqueness Of Man makes the novel point that just as man is unique in being the only animal which requires a long period of infancy and childhood under family protection, so is he the only animal who has a long period after the decline of his procreativity.

The technological, operative approach, which she calls extraverted, and the mystic, contemplative, psychological one, which she calls introverted are not mutually exclusive, but complementary instead, as meditation requires practice in the real world, and conversely.

The use of multi-defined words requires the author or speaker to clarify their context, and sometimes elaborate on their specific intended meaning ( in which case, a less ambiguous term should have been used ).

The debate is interesting enough, however, that it is considered of note when a theorem in ZFC ( ZF plus AC ) is logically equivalent ( with just the ZF axioms ) to the axiom of choice, and mathematicians look for results that require the axiom of choice to be false, though this type of deduction is less common than the type which requires the axiom of choice to be true.

When infants are taught to sign, parents are able to converse with them at a developmental stage when they are not yet capable of producing vocal speech, which requires fine control of both breathing and the vocal tract.

According to Steven H Silver, alternate history requires three things: 1 ) the story must have a point of divergence from the history of our world prior to the time at which the author is writing, 2 ) a change that would alter history as it is known, and 3 ) an examination of the ramifications of that change.

Every field has an algebraic extension which is algebraically closed ( called its algebraic closure ), but proving this in general requires some form of the axiom of choice.

This inhibition of MAO-A allows DMT to diffuse unmetabolized past the membranes in the stomach and small intestine, and eventually cross the blood – brain barrier ( which, by itself, requires no MAO-A inhibition ) to activate receptor sites in the brain.

This requires developing new faculties of objective spiritual perception, which Steiner maintained was possible for humanity today.

This portability feature, however, requires a portable television, which was extremely rare in the early 1980s.

Their main disadvantage is the distortion of the flow itself by the structure supporting the transducers, which requires a correction based upon wind tunnel measurements to minimize the effect.
