Nevertheless, as a rule of thumb, high-performance parallel computation in a shared-memory multiprocessor uses parallel algorithms while the coordination of a large-scale distributed system uses distributed algorithms.

Indeed, that is a good rule of thumb in deconstruction.

For example, he coined the programming phrase " two or more, use a for ," alluding to the rule of thumb that when you find yourself processing more than one instance of a data structure, it is time to consider encapsulating that logic inside a loop.

A practical method of determining whether an enantiomer is R or S is by using the right-hand rule: one wraps the molecule with the fingers in the direction 1 → 2 → 3.

If a is a point in R < sup > n </ sup >, then the higher dimensional chain rule says that:

If is an outward pointing in-plane normal, whereas is the unit vector perpendicular to the plane ( see caption at right ), then the orientation of C is chosen so that a tangent vector to C is positively oriented if and only if forms a positively oriented basis for R < sup > 3 </ sup > ( right-hand rule ).

Altruism is known to increase from rarity when relatedness ( R ) exceeds the ratio of the cost ( C ) to the altruist ( in this case, the cell giving up its own reproduction by differentiating ), to the benefit ( B ) to the recipient of altruism ( the germ line of the colony, that reproduces as a result of the differentiation ), i. e. R > C / B ( see Hamilton's rule ).

In Principles ( 1973 ) R. M. Hare accepts that rule utilitarianism collapses into act utilitarianism but claims that this is a result of allowing the rules to be ' as specific and un-general as we please.

For example, for ground stations at latitudes of φ = ± 45 ° on the same meridian as the satellite, the time taken for a signal to pass from Earth to the satellite and back again can be computed using the cosine rule, given the geostationary orbital radius r ( derived below ), the Earth's radius R and the speed of light c, as

There is, however, no strict rule and the host is appointed by the R & A roughly five years in advance.

Consistent with this rule, strong bases such as alkoxide ( RO < sup >−</ sup >), hydroxide ( HO < sup >−</ sup >), and amide ( R < sub > 2 </ sub > N < sup >−</ sup >) are poor leaving groups.

Likewise, the rule (¬ R ) states that, if Γ and A suffice to conclude Δ, then from Γ alone one can either still conclude Δ or A must be false, i. e. ¬ A holds.

For an intuition about the quantifier rules, consider the rule (∀ R ).

As a general rule judges cannot direct juries to draw adverse inferences from a defendant's silence ( Petty v R ) but there are exceptions to this rule, most notably in cases which rely entirely on circumstantial evidence which it is only possible for the defendant to testify about ( Weissensteiner v R ).
