were irrational, then the wave would not be periodic. Periodic function In mathematics, a periodic function is a function that repeats its values in regular intervals or periods. The most important examples are the trigonometric functions, which repeat over intervals of 2"π" radians. Periodic functions are used throughout science to describe oscillations, waves, and other phenomena that exhibit periodicity. Any function that is not periodic is called aperiodic. A function is said to be periodic if, for some nonzero constant , we have for all values of in the domain. A nonzero constant for which this is the case is

show periodic behaviour. Periodic motion is motion in which the position(s) of the system are expressible as periodic functions, all with the "same" period. For a function on the real numbers or on the integers, that means that the entire graph can be formed from copies of one particular portion, repeated at regular intervals. A simple example of a periodic function is the function formula_6 that gives the "fractional part" of its argument. Its period is 1. In particular, The graph of the function formula_6 is the sawtooth wave. The trigonometric functions sine and cosine are common periodic functions, with

Quasiperiodicity Quasiperiodicity is the property of a system that displays irregular periodicity. Periodic behavior is defined as recurring at regular intervals, such as "every 24 hours". Quasiperiodic behavior is a pattern of recurrence with a component of unpredictability that does not lend itself to precise measurement. It is different from the mathematical concept of an almost periodic function, which has increasing regularity over multiple periods. The mathematical definition of quasiperiodic function is a completely different concept; the two should not be confused. In climatology, oscillations that appear to follow a regular pattern but which do not have a fixed period

In "The Destruction of Sennacherib", each line has the basic pattern of two unstressed syllables followed by a third stressed syllable, with this basic pattern being repeated four times in a line. Those basic patterns are called feet, and this particular pattern (weak weak STRONG) is called an anapest. A line with four feet is said to be in tetrameter ("", from the Greek for four).

lists several factors in Russian folk music which contribute to this pattern of inertia. Melodies in Russian folk songs are self-contained, with no interaction between themes in contrasting musical keys or any clear transition from one theme to another. Instead, melodies are repeated, "using similar intervals and phrases with an almost ritual insistence," according to musicologist John Warrack. This makes many folk songs essentially a series of variations on one basic shape or pattern of a few notes. The problem with repetition is that, even with a surface level of rhythmic activity added, the melody remains static over a period

This repeat distance is referred to as the depth or "z"-axis value of a particular pattern in the autostereogram. The depth value is also known as Z-buffer value. The brain is capable of almost instantly matching hundreds of patterns repeated at different intervals in order to recreate correct depth information for each pattern. An autostereogram may contain some 50 tigers of varying size, repeated at different intervals against a complex, repeated background.

Its derivatives and idiosyncratic imitations are often characterized as "cul-de-sac and loop" patterns highlighting the distinguishing street types that are used systematically in this network. A second term equally uncharacteristic is "suburban". This association of a pattern with a location is inaccurate and unintentionally misleading: entire early cities such as Cairo and Fez are structured on this pattern whose newer suburbs follow the grid reversing the urban/suburban relationship. "Suburban" is also devoid of geometric descriptors of the pattern. These shorthand expressions

motion can be perceived at various speeds. If the imagined motion is in the same direction as that experienced during adaptation, imagined speed is slowed; when imagined motion is in the opposite direction, its speed is increased; when adaptation and imagined motions are orthogonal, imagined speed is unaffected. Studies using magnetoencephalography (MEG) have demonstrated that subjects exposed to a repeated visual stimulus at brief intervals become attenuated to the stimulus in comparison to the initial stimulus. The results revealed that visual responses to the repeated compared with novel stimulus showed a significant reduction in both activation strength and peak latency

Daychovo horo Daichovo horo () is a Bulgarian folk dance done to a 9 beat meter. It is unique in two ways: it is a circle dance (most Bulgarian dances are either line or couple dances), and yet it has a leader (most circle dances have no leader). The dance has a basic step pattern consisting of a lift of the right knee on the first beat, followed by three steps in place. This pattern is repeated, alternating which knee is lifted. Each pattern is done in a single measure of 9 beats () with a pattern counted 2-2-2-3 or

Robust confidence intervals In statistics a robust confidence interval is a robust modification of confidence intervals, meaning that one modifies the non-robust calculations of the confidence interval so that they are not badly affected by outlying or aberrant observations in a data-set. In the process of weighing 1000 objects, under practical conditions, it is easy to believe that the operator might make a mistake in procedure and so report an incorrect mass (thereby making one type of systematic error). Suppose he has 100 objects and he weighed them all, one at a time, and repeated the whole process ten times.

We now know that the speed of light is far too fast to be measured by such methods (with human shutter-openers on Earth). Galileo put forward the basic principle of relativity, that the laws of physics are the same in any system that is moving at a constant speed in a straight line, regardless of its particular speed or direction. Hence, there is no absolute motion or absolute rest. This principle provided the basic framework for Newton's laws of motion and is central

Example 4 shows a dissonant cambiata in fifth species. Outside species counterpoint, what is considered a cambiata varies. What is common to all is that a note is skipped from in one direction and this is followed by motion in the opposite direction, and either the note skipped from is distinguished as a dissonance or the note skipped to is distinguished as a non-chordal tone.

would probably apply to the Arabia quadrangle as well. The pattern of layers within layers measured in Becquerel crater, suggests that each layer was formed over a period of about 100,000 years. Moreover, every 10 layers were bundled together into larger units. The 10-layer pattern is repeated at least 10 times. So every 10-layer pattern took one-million-year years to form. It is believed that the regular pattern of layers in Arabia is connected to the regular way in which the rotational axis of Mars changes. The tilt of the Earth's axis changes by only a little more than 2 degrees.

This pattern of discounting is dynamically inconsistent (or time-inconsistent), and therefore inconsistent with basic models of rational choice, since the rate of discount between time "t" and "t+1" will be low at time "t-1" when "t" is the near future, but high at time "t" when "t" is the present and time "t+1" is the near future. This pattern can also be explained through models of sub-additive discounting that distinguish the delay and interval of discounting: people are less patient (per-time-unit) over shorter intervals regardless of when they occur.

A light wave that is incident on a grating is split into several waves; the direction of these diffracted waves is determined by the grating spacing and the wavelength of the light. A simple hologram can be made by superimposing two plane waves from the same light source on a holographic recording medium. The two waves interfere, giving a straight-line fringe pattern whose intensity varies sinusoidally across the medium. The spacing of the fringe

main stimulant of the basic cry. An anger cry is much like the basic cry; however, in this cry, more excess air is forced through the vocal cords, making it a louder, more abrupt cry. This type of cry is characterized by the same temporal sequence as the basic pattern but distinguished by differences in the length of the various phase components. The third cry is the pain cry, which, unlike the other two, has no preliminary moaning. The pain cry is one loud cry, followed by a period of breath holding. Most adults can determine whether an infant's cries

The segmental pattern of the skeleton is present in all vertebrates (mammals, birds, fish, reptiles and amphibians) with basic units being repeated. This segmental pattern is particularly evident in the vertebral column and the ribcage. Bones in addition to supporting the body also serve, at the cellular level, as calcium and phosphate storage. The skeleton, which forms the support structure inside the fish is either made of cartilage as in the (Chondrichthyes), or bones as in the (Osteichthyes).

For the sake of novelty, IMAX and other panoramic type theaters often show dramatic motions such as flying over a landscape or riding a roller coaster. This type of motion sickness can be prevented by closing one's eyes during such scenes. In regular-format theaters, an example of a movie that caused motion sickness in many people is "The Blair Witch Project". Theaters warned patrons of its possible nauseating effects, cautioning pregnant women in particular. "Blair Witch" was filmed with a handheld camcorder, which was subjected to considerably more

speed and certain type of bowling balls. If a bowler has a specific form of bowling suitable for a specific oil pattern, coupled with the right bowling ball, his margin of error is highly increased versus other bowlers. The result is that sometimes the bowler throwing the more accurate shot loses to the bowler who has created a larger "target area". Some advanced bowlers simplified this to: "To a large degree, the equipment and oil pattern determines the winner." At the end of 2007, the USBC completed a two-year study on bowling ball motion and how advanced, high-tech equipment may

When viewed under normal light, this is a normal water fountain. When viewed under a strobe light with its frequency tuned to the rate at which the droplets fall, the droplets appear to be suspended in mid-air. Adjusting the strobe frequency can make the droplets seemingly move slowly up or down.

Pattern (sewing) In sewing and fashion design, a pattern is the template from which the parts of a garment are traced onto fabric before being cut out and assembled. Patterns are usually made of paper, and are sometimes made of sturdier materials like paperboard or cardboard if they need to be more robust to withstand repeated use. The process of making or cutting patterns is sometimes condensed to the one-word Patternmaking, but it can also be written pattern(-)making or pattern cutting. A sloper pattern (home sewing) or block pattern (industrial production) is a custom-fitted, basic pattern from which patterns for

I-AA-BB-C(C)-Br-C-Br-C(Grandioso) Another popular (and perhaps older) march style is the regimental march, or review march. There are a few key differences between a typical military march and a regimental march. Therefore, the "regimental" march form is this: I-AA-BB-CC-DD The basic (and vague) definition of a march is a piece of music based upon a regular repeated drum/rhythmic pattern. Therefore, what makes a march recognizable is its phrases. Almost all quickstep marches consist of four-measure phrases, typical ending with a whole note either creating or resolving melodic tension (see Progressions) followed by a pickup note (see Pickups).

At regular intervals during the game, the player will face a swarm of enemies (bees, dragonflies, etc.) instead of the usual millipede. Each enemy destroyed awards increasing points, up to a maximum of 1,000 points per enemy; this attack ends when either the entire swarm has passed or the player loses a life. Also, at intervals new mushrooms will grow on the field while others die off, in a pattern similar to Conway's Game of Life. Players can also choose at

Regular ovulation is usually indicated by predictable and consistent intervals between menses, predictable and consistent durations of menses, and predictable and consistent patterns of flow (e.g., heaviness or cramping). Continuing ovulation typically requires a body fat content of at least 22%. An anthropological term for this state of potential fertility is nubility. On the other hand, not every girl follows the typical pattern, and some girls ovulate

Hyperlapse Hyperlapse (also walklapse, spacelapse, stop-motion time-lapse, moving timelapse) is a technique in time-lapse photography that allows the photographer to create motion shots. In its simplest form, a hyperlapse is achieved by manually moving the camera a short distance between each shot. The first film using the hyperlapse technique dates to 1995. Regular timelapse involves taking photos at a regular interval with a camera mounted on a tripod or using a motorized dolly and/or pan-and-tilt head to add limited motion to the shot. Hyperlapse relies on the same basic principle, but adds movement over much longer distances. This movement is

Mobitz differentiated two types of second degree AV block with the aid of the electrocardiogram and characterized their prognostic significance. With type I (Mobitz type I), the PR interval increases gradually until there is a breakdown of AV conduction. This form is identical to the previously described type of second-degree AV block by Wenckebach at the end of the nineteenth century. With type II block (Mobitz type II), all conducted beats show a constant, typically normal PR interval, and conduction to the ventricles occurs at regular intervals. This form is identical to the type of AV block described by Hay

Basic income in Germany Basic income in Germany ("German: Grundeinkommen"), has been discussed since the 1970s, with emphasis placed on its unconditional dimension by 2003. The basic income concept has many definitions, such as Philippe van Farijs', which described it as the income paid by the government, at a uniform level and regular intervals to each adult citizen and permanent residents of the country. The Basic Income Earth Network's criteria constitute one of the most popular proposals and they include: 1) income must be paid to individuals instead of households; 2) income should be paid irrespective of income from other

type II is also named for John Hay. Type 1 Second-degree AV block, also known as Mobitz I or Wenckebach periodicity, is almost always a disease of the AV node. Wenckebach published a paper in 1906 on progressively lengthening PR intervals that was later classified as Type I in Mobitz's 1924 paper. Thus, both "Mobitz type I" and "Wenckebach block" refer to the same pattern and pathophysiology. In Wenckebach's 1906 paper, his original observations were from increasing delay in contraction of the atria & ventricles that shortened after a brief pause and this was later observed on ECG after Einthoven's

Mozart sometimes used a variant type of sonata rondo form in which the themes of the recapitulation are rearranged: the opening bars reappear quite late, after most of the music of the exposition has been recapitulated, but before the final sequence of themes ("Codetta") that rounds off the section. Thus: Mozart's purpose was perhaps to create a sense of variety by not having the main theme return at such regular intervals.

The α-helical domain has 310-150 amino acids and comprises four segments in which a seven-residue pattern repeats. Into this repeated pattern, the first and fourth residues are hydrophobic and the charged residues show alternate positive and negative polarity, resulting in the polar residues being located on one side of the helix.

The randomness of these sequences has been examined by diehard tests. Repeating decimal A repeating or recurring decimal is decimal representation of a number whose digits are periodic (repeating its values at regular intervals) and the infinitely repeated portion is not zero. It can be shown that a number is rational if and only if its decimal representation is repeating or terminating (i.e. all except finitely many digits are zero). For example, the decimal representation of ⅓ becomes periodic just after the decimal point, repeating the single digit "3" forever, i.e. 0.333…. A more complicated example is , whose decimal

The first is Pollock's motion as he moved around the canvas, which Taylor hypothesized followed a Levy flight, a type of chaotic motion that is known to leave behind a fractal pattern. More specifically, a number of studies have shown that the motions associated with human balance have fractal characteristics.
