Their work was based on the valence bond model, which assumes that a chemical bond is formed when there is good overlap between the atomic orbitals of participating atoms.

The underlying model assumes chi-squared dissimilarities among records ( cases ).

The XCAST model generally assumes that the stations participating in the communication are known ahead of time, so that distribution trees can be generated and resources allocated by network elements in advance of actual data traffic.

: Note this model assumes the particle is a point mass, which is certainly known to be false in many cases in which we use this model ; for example, as a model of planetary motion.

The model further assumes that the consumer has a budget M which is used to purchase a vector x < sub > 1 </ sub >, x < sub > 2 </ sub >,..., x < sub > n </ sub > in such a way as to maximize U ( x < sub > 1 </ sub >, x < sub > 2 </ sub >,..., x < sub > n </ sub >).

As noted above, an influential model of perfect competition in neoclassical economics assumes that the number of buyers and sellers are both of the power of the continuum, that is, an infinity even larger than the number of natural numbers.

An alternative model assumes that PrP < sup > Sc </ sup > exists only as fibrils, and that fibril ends bind PrP < sup > C </ sup > and convert it into PrP < sup > Sc </ sup >.

A statistical model may be used to describe the set of distributions from which one assumes that a particular data set is sampled.

For example, if one assumes that data arise from a univariate Gaussian distribution, then one has assumed a Gaussian model:.

The model of prices being determined by supply and demand assumes perfect competition.

A physical model of telepathy, whether described as radiational or in other terms, assumes that transference is effected by means of a vibratory current linking one brain to another.

The ideal model not only neglects basic physics factors in terms of primary current required to establish a magnetic field in the core and the contribution to the field due to current in the secondary circuit but also assumes a core of negligible reluctance with two windings of zero resistance.

The ideal transformer model assumes that all flux generated by the primary winding links all the turns of every winding, including itself.

Conservatives would subscribe more strongly and more often to a model that he calls the " strict father model " and has a family structured around a strong, dominant " father " ( government ), and assumes that the " children " ( citizens ) need to be disciplined to be made into responsible " adults " ( morality, self-financing ).

Mechanistic determinism assumes that every event has an unbroken chain of prior occurrences, but a selectionistic or probabilistic model does not.

This model assumes a mass production of culture and identifies power as residing with those producing cultural artifacts.

The MTBF is typically part of a model that assumes the failed system is immediately repaired ( MTTR ), as a part of a renewal process.

It assumes a desire to ‘ develop ’ along the traditional ' Western ' model of economic development which a few countries, such as Cuba and Bhutan, have chosen not to allow their citizens to follow.

For electromagnets ( or permanent magnets ) with well defined ' poles ' where the field lines emerge from the core, the force between two electromagnets can be found using the ' Gilbert model ' which assumes the magnetic field is produced by fictitious ' magnetic charges ' on the surface of the poles, with pole strength m and units of Ampere-turn meter.

An alternative model, known as the-disk, which is stable in both sense assumes that the viscosity is proportional to the gas pressure.

While there may be several such industries to which the model of this paper is applicable, the authors make particular claim of relevance to the explanation of the course of wages and prices in the steel industry of the United States since World War 2.

Note that any model of ZF ¬ C is also a model of ZF, so for each of the following statements, there exists a model of ZF in which that statement is true.

* There exists a model of ZF ¬ C in which there is a function f from the real numbers to the real numbers such that f is not continuous at a, but f is sequentially continuous at a, i. e., for any sequence

Early mathematicians regarded axiomatic geometry as a model of physical space, and obviously there could only be one such model.

The Bohr model of the atom fixed the problem of energy loss from radiation from a ground state ( by declaring that there was no state below this ), and more importantly explained the origin of spectral lines.

Besides the two for the Roman Pontiffs already mentioned, there is one for Alfieri, another for Emo, a Venetian admiral, and a small model of a cenotaph for Horatio Nelson, besides a great variety of monumental relieves such as the Stele Tadini in the Chapel of the Accademia Tadini in Lovere.

After selling a few kits, MCP became convinced there was a much bigger market for an improved model sold as a completed working system.

A key point which is often overlooked is that published lower bounds for problems are often given for a model of computation that is more restricted than the set of operations that you could use in practice and therefore there are algorithms that are faster than what would naively be thought possible.

These orbits were stabilized in the model by the fact that when an electron moved farther from the center of the positive cloud, it felt a larger net positive inward force, because there was more material of opposite charge, inside its orbit ( see Gauss's law ).

In the United States there is a proportionally limited tax on alcopops relative to those sold in Europe, although some states are considering legislation to bring their tax levels closer to the European model, which is credited with limiting consumption by youth.

As noted above, there is no well-supported model describing the action prior to 10 < sup >− 15 </ sup > seconds or so.

But there are, however, two incentives to use the chassis + body model.

Despite the study of model plants and increasing use of DNA evidence, there is ongoing work and discussion among taxonomists about how best to classify plants into various taxa.

The physical model behind cosmic inflation is extremely simple, however it has not yet been confirmed by particle physics, and there are difficult problems reconciling inflation and quantum field theory.

Gurevich adds the pointer machine model of Kolmogorov and Uspensky ( 1953, 1958 ): "... they just wanted to ... convince themselves that there is no way to extend the notion of computable function.

Programs developed there became a model for the new field of social work.

Such confidence in the group to find the ground truth is explicable through the success of wisdom of the crowd based inferences, however, if there is no access to the ground truth, as there was not in this model, the method will fail.

A maturity model can be used as a benchmark for comparison and as an aid to understanding-for example, for comparative assessment of different organizations where there is something in common that can be used as a basis for comparison.

During a Council of Australian Governments meeting of 2007, model legislation to rework double jeopardy laws was drafted, but there was no formal agreement for each state to introduce it.

A real number a is first-order definable in the language of set theory, without parameters, if there is a formula φ in the language of set theory, with one free variable, such that a is the unique real number such that φ ( a ) holds in the standard model of set theory ( see Kunen 1980: 153 ).
