The client, instead of writing code that invokes the " new " operator on a hard-coded class name, calls the clone () method on the prototype, calls a factory method with a parameter designating the particular concrete derived class desired, or invokes the clone () method through some mechanism provided by another design pattern.

In cases such as the 1981 assassination attempt on President Ronald Reagan however, this method of designating an acting president could have been justified, in consideration of the fact that Reagan was literally unable to give any orders in the immediate aftermath of the shooting.

Similarly, he favoured the method of naming families after one of the constituent genera, rather than some defining feature of the group, implicitly designating a type genus for the family.

Because of its simplicity, star hopping is a very common method for finding objects that are close to naked-eye stars.

Ptolemy's method of connecting the stars of Capricornus has been influential.

In another form of the method, timing the eclipses in an eclipsing binary star can reveal an outer planet that orbits both stars ; as of November 2011, five planets have been found in that way.

This method has resulted in only 13 detections as of June 2011, but it has the advantage of being especially sensitive to planets at large separations from their parent stars.

* Multi-conjugate Adaptive optics Demonstrator, astronomical method of using multiple guide stars and deformable mirrors to sense and correct for the distortions produced by turbulence in Earth's atmosphere

This method is less likely to be successful for sighting stars and planets.

Astronomers of the era expected that changes over time in the apparent separation and relative location of these stars would provide evidence for both the proper motion of stars and, by means of parallax shifts in their separation, for the distance of stars from the Earth ( a method first suggested by Galileo Galilei ).

Ptolemy measured the longitudes of Regulus, Spica, and other bright stars with a variation of Hipparchus ' lunar method that did not require eclipses.

This method works well for capturing images of the moon and brighter planets, as well as narrow field images of stars and nebulae.

The ancient Egyptians based their calendar on the heliacal rising of Sirius and devised a method of telling the time at night based on the heliacal risings of 36 stars called decan stars ( one for each 10 ° segment of the 360 ° circle of the zodiac / calendar ).

They studied the stars and nature, and used the information they gleened, as a method of understanding their Creator and themselves.

In 1989, the satellite Hipparcos was launched primarily for obtaining parallaxes and proper motions of nearby stars, increasing the reach of the method tenfold.

The same method has also been used to detect planets around stars, in the way that the movement's measurement determines the planet's orbital period, while the resulting size of the displacement allows the calculation of the lower bound on a planet's mass.

These include measuring the luminosity of planetary nebulae, comparison with nearby galaxies whose distance has been estimated using standard candles such as cepheid variables, the linear size distribution of globular clusters, and the tip of the red giant branch method using individually resolved red giant stars.

With the object of testing the capabilities of the method, he took for his first essay the well-known star 61 Cygni, and his results agreed so well with those previously attained that he undertook the systematic measurement of the parallaxes of second-magnitude stars, and published the outcome in the third and fourth volumes of the Publications of the Oxford University Observatory.

Pierre Bouguer gains the award for his paper On the masting of ships ; and two other prizes, one for his dissertation On the best method of observing the altitude of stars at sea and the other for his paper On the best method of observing the variation of the compass at sea.

It was dedicated to the search for planets around other stars using the transit method.

In 1727 he gained the prize given by the French Academy of Sciences for his paper On the masting of ships, beating Leonhard Euler ; and two other prizes, one for his dissertation On the best method of observing the altitude of stars at sea, the other for his paper On the best method of observing the variation of the compass at sea.

In 1882, Pickering developed a method to photograph the spectra of multiple stars simultaneously by putting a large prism in front of the photographic plate.

The first diatomic hydride investigated by the paramagnetic resonance method was the OH radical.

Another method of assuring a clean hole is to first drill a small pilot hole all the way through, then drill half way with the dimensional bit, turn the piece over, and finish from the other side.

The third method was, to our knowledge, successfully applied for the first time by C. Sheer and co-workers ( Ref. 2 ).

The first argument is thus an ideal experiment in which we use the method of difference.

Although the first polyether foams on the market had to be produced by the two-step prepolymer method, today, thanks to new catalysts, they can be produced by a one-shot technique.

In the mid-1870s, a form of amplitude modulation — initially called " undulatory currents "— was the first method to successfully produce quality audio over telephone lines.

After the team had developed a method of purifying penicillin to an effective first stable form in 1940, several clinical trials ensued, and their amazing success inspired the team to develop methods for mass production and mass distribution in 1945.

His experimental method had been influenced by his meetings with various members of the Bauhaus design school, especially László Moholy-Nagy, whom he first met in 1930.

The atom probe is closely related to the method of Field Ion Microscopy, which is the first microscopic method to achieve atomic resolution, occurring in 1951.

By " computerizing " this method of communications, the name of the first BBS system was born: CBBS-Computerized Bulletin Board System.

It was also the first BBS to produce audio for its visitors, broadcasting news about screen printing and music in a pre-recorded method in what was the precursor to Internet Radio.

The 1971 census was the first census in Botswana to use de facto enumeration ; this method counts people based on how many people spent census night at a specific location.

After that, the first method can be used to crack the PIN.

The first person to describe the mathematics behind Brownian motion was Thorvald N. Thiele in a paper on the method of least squares published in 1880.

The classic interpretation of blitzkrieg is that of German tactical and operational methodology in the first half of the Second World War that was often hailed as a new method of warfare.

But the study of these curves was first developed in 1959 by mathematician Paul de Casteljau using de Casteljau's algorithm, a numerically stable method to evaluate Bézier curves.

The method usually adopted were membership rules to ensure that anyone newly joining a society would, for the first few years, be unable to get any profit out of a demutualisation.

Both the first method for cladistic analysis and the school of taxonomy originated in the work of the German entomologist Willi Hennig, who referred to it as " phylogenetic systematics " ( also the title of his 1966 book ); the use of the terms cladistics and clade was popularized by other researchers.

Despite its difficulty of learning, this method remains popular in Chinese communities that use traditional Chinese characters, such as Hong Kong and Taiwan ; it is also the first method that allowed users to enter more than a hundred Chinese characters per minute.

Bimba also developed the first Capoeira systematical training method.

Bimba created his sequências de ensino ( teaching combinations ) and created Capoeira's first teaching method.

Capoeira Regional also introduced the first ranking method in Capoeira.

It elects one Member of Parliament ( MP ) by the first past the post system of election, and is part of the South West England constituency of the European Parliament which elects six MEPs using the d ' Hondt method of party-list proportional representation.
