Convergence (Anthromorphemics)

The evolution of nonhomologous similarities in different evolutionary lines; the result of similarities in selective pressures.

Convergence (Anthropology)

The evolution of nonhomologous similarities in different evolutionary lines; the result of similarities in selective pressures.

Convergence (Bioinformatics)

The end-point of any algorithm that uses iteration or recursion to guide a series of data processing steps. An algorithm is usually said to have reached convergence when the difference between the computed and observed steps falls below a pre-defined threshold.

Convergence (Climate)

The quasi-horizontal flow of a fluid toward a common destination from different directions. When waters of different origins come together at a point or along a line (convergence line), the denser water from one side sinks under the lighter water from other side. The ocean convergence lines are the polar, subtropical, tropical, and equatorial. Also see divergence.

Convergence (Climatology)

Coming together; "piling up" of mass. Surface convergence occurs in association with rising air whereas upper-level convergence is associated with subsidence.

Convergence (Computer Monitor)

Alignment of the vertical and horizontal lines in an image.

Convergence (Computer Technology)

The ability of the three electron beams (red, green and blue) in a CRT monitor to meet at a single point and produce one dot. If a monitor is mis-converging, you will notice shadows of blue or red around any white images. Often, this will occur in only some parts of the screen. Some monitors have convergence controls, but most do not.

Convergence (E-Learning)

A result of the digital era in which various types of digital information, such as text, audio, and video, and their delivery mechanisms--television, telecommunications, and consumer electronics--are combined together in new integrated forms. WebTV is an example of convergence between televisions and computer technology.

Convergence (Evolution)

The process by which a similar character evolves independently in two species. Also, a synonym for analogy; that is, an instance of a convergently evolved character, or a similar character in two species that was not present in their common ancestor. Examples include wings (convergent in birds, bats, and insects) and camera-type eyes (convergent in vertebrates and cephalopod mollusks).

Convergence (Finance)

The movement of the price of a futures contract toward the price of the underlying cash commodity. At the start, the contract price is higher because of time value. But as the contract nears expiration, and time value decreases, the futures price and the cash price converge.

Convergence (Financial)

Is the behavior of a cash commodity or the underlying security instrument and the derivative moving towards one another. Is the behavior of a cash commodity or the underlying security instrument and the derivative moving towards one another.

Convergence (Home Audio)

The alignment of the red, green and blue scanning electron beams on a projected display when the lines produced by the three color guns appear to form one clearly focused white line. The point at which the perimeters of multiple lenses align so that the perceived single image is clearly focused. Misaligned beams degrade the quality of the picture.

Convergence (Hurricane)

Wind movement that results in a horizontal net inflow of air into a particular region. Convergent winds at lower levels are associated with upward motion. Contrast with divergence.

Convergence (Interactive Services Marketing)

The combining of information technologies that were previously considered distinct and separate (e.g., telephones and television) but are now beginning to overlap and converge on each other.

Convergence (International Economics)

The process of becoming quantitatively more alike. In an international context, it often refers to countries becoming more alike in terms of their factor prices or in terms of their per capita incomes, perhaps as a result of trade or other forms of economic integration.

Convergence (Photography)

The phenomenon in which lines that are parallel in a subject, such as the vertical lines of a building, appear nonparallel in a image .

Convergence (Physical Geography)

Horizontal inflow of wind into an area. Once at the area, the wind then travels vertically.

Convergence (Satellite Meteorology)

The horizontal coming-together of air that can lead to lifting.

Convergence (Technology)

The ability of the three electron beams (red, green and blue) in a CRT monitor to meet at a single point and produce one dot. If a monitor is mis-converging, you will notice shadows of blue or red around any white images. Often, this will occur in only some parts of the screen. Some monitors have convergence controls, but most do not.

Convergence (Television)

(1) The correct aiming of the three electron beams in a direct viewed picture tube or three separate pictures from tubes in a projection TV (for red, blue, and green) to be together at all times. Without proper convergence, objects on the screen will have colored halos around them, white lines will seem to have a red, green, or blue line next to them, and resolution will be poorer. The most common reason for misconvergence is the coils attached to the neck of the picture tube not in the proper position which usually takes a time consuming trial and error process to correct. Often perfect convergence cannot be achieved over the entire screen so a compromise where the errors are minimized but not completely eliminated must be accepted. It may be noted that a convergence error of one fifth of one percent means that one of the electron beams is off by a scan line causing a halving of the resolution at that spot on the screen. ("Convergence" for projection TV with several CRT's is also called "registration".) (2) The bringing together and integrating of two or more systems or technologies so that components can be shared. An example is the development and manufacturing of video monitors suitable for television, movies, and entertainment, and also suitable for computers and data display.

Convergence (Video)

Three colors-red, blue, and green-are used in television to produce all colors. These separate scanning beams (one for each color) must strike their targeted phosphors (screen's internal coating) with precise accuracy. If the beams are out of alignment, then the image and colors appear muddied.

Convergence (Weather)

A contraction of a vector field; the opposite of divergence. Convergence in a horizontal wind field indicates that more air is entering a given area than is leaving at that level. To compensate for the resulting "excess," vertical motion may result: upward forcing if convergence is at low levels, or downward forcing (subsidence) if convergence is at high levels. Upward forcing from low-level convergence increases the potential for thunderstorm development (when other factors, such as instability, are favorable). Compare with confluence.
