Function |
A Function is a term-forming Relation that maps from a n-tuple of arguments to a range and that associates this n-tuple with at most one range element. Note that the range is a Class, and each element of the range is an instance of the Class.
|
| |
InheritableRelation |
The class of Relations whose properties can be inherited downward in the class hierarchy via the subrelation Predicate.
|
| |
TernaryRelation |
TernaryRelations relate three items. The two subclasses of TernaryRelation are TernaryPredicate and BinaryFunction.
|
| Children |
AssociativeFunction | A BinaryFunction is associative if bracketing has no effect on the value returned by the Function. More precisely, a Function ?FUNCTION is associative just in case (?FUNCTION ?INST1 (?FUNCTION ?INST2 ?INST3)) is equal to (?FUNCTION (?FUNCTION ?INST1 ?INST2) ?INST3), for all ?INST1, ?INST2, and ?INST3. |
| | CommutativeFunction | A BinaryFunction is commutative if the ordering of the arguments of the function has no effect on the value returned by the function. More precisely, a function ?FUNCTION is commutative just in case (?FUNCTION ?INST1 ?INST2) is equal to (?FUNCTION ?INST2 ?INST1), for all ?INST1 and ?INST2. |
| Instances | AbortedFn | (AborteFn ?AGENT ?PROCESS) is the Process ?PROCESS after it has gotten aborted by the AutonomousAgent ?AGENT |

| | BirthsPerThousandFn | (BirthsPerThousandFn ?AREA ?YEAR) denotes the RealNumber that represents the number of births per thousand individuals in the population of the GeopoliticalArea ?AREA for Year ?YEAR. This number gives the average annual number of births during a year per 1,000 persons in the population at midyear, also known as crude birth rate. The birth rate is usually the dominant factor in determining the rate of population growth. It depends on both the level of fertility and the age structure of the population. |
| | BodySideFn | A Function that takes a BodyPart that normally exists in pairs and returns the part that is on the given side of the body, for example (BodyPartFn Right Lung) or (BodyPartFn Left Arm). |

| | ChildrenBornPerWomanFn | This entry gives a figure for the average number of children that would be born per woman if all women lived to the end of their childbearing years and bore children according to a given fertility rate at each age. The total fertility rate is a more direct measure of the level of fertility than the crude birth rate, since it refers to births per woman. This indicator shows the potential for population growth in the country. High rates will also place some limits on the labor force participation rates for women. Large numbers of children born to women indicate large family sizes that might limit the ability of the families to feed and educate their children. |

For example, (DayFn 16 August) is the Class of all sixteenth days of August. For another example, (DayFn 9 Month) would return the class of all ninth days of any month. For still another example, (DayFn 18 (MonthFn August (YearFn 1912))) denotes the 18th day of August 1912. |
| | DeathsPerThousandFn | (DeathsPerThousandFn ?AREA ?YEAR) denotes the RealNumber that represents the number of deaths per thousand individuals in the population of the GeopoliticalArea ?AREA for Year ?YEAR. This number gives the average annual number of deaths during a year per 1,000 population at midyear, also known as crude death rate. The death rate, while only a rough indicator of the mortality situation in a country, accurately indicates the current mortality impact on population growth. This indicator is significantly affected by age distribution, and most countries will eventually show a rise in the overall death rate, in spite of continued decline in mortality at all ages, as declining fertility results in an aging population. |
| | DeathsPerThousandLiveBirthsFn | (DeathsPerThousandLiveBirthsFn ?AREA ?YEAR) denotes the RealNumber that represents the number of deaths of infants under one year old in a given year per 1,000 live births in the same year.

| | DirectionalSubregionFn | (DirectionalSubregionFn ?DIRECTION ?AREA) denotes the part of GeographicArea ?AREA that lies in ?DIRECTION from the geographic center of ?AREA. For example, (DirectionalSubregionFn Iraq North) denotes the Northern part of Iraq. Such subregions are defined purely by geographical points of reference, not by sociological ones. For example, (DirectionalSubregionFn UnitedStatesOfAmerica South) denotes the Southern half of the United States, it does not denote the American South as distinguished for historical, literary, or cultural purposes. |
| | DivisionFn | If ?NUMBER1 and ?NUMBER2 are Numbers, then (DivisionFn ?NUMBER1 ?NUMBER2) is the result of dividing ?NUMBER1 by ?NUMBER2.

For example, we can denote the Class of prime numbers that are less than 100 with the following expression: (KappaFn ?NUMBER (and (instance ?NUMBER PrimeNumber) (lessThan ?NUMBER 100))). Note that the use of this function is discouraged, since there is currently no axiomatic support for it. |
| | LevelPlaneFn | LevelPlaneFn is a Function that takes a PointInSpace of a Region and an AstronomicalBody and denotes the Plane that is perpendicular to the line formed by the PointInSpace and center of the AstronomicalBody. |
| | LifeExpectancyAtBirthFn | (LifeExpectancyAtBirthFn ?AREA ?YEAR) denotes the RealNumber that represents the average number of years to be lived by a group of people born in the same year, if mortality at each age remains constant in the future. Life expectancy at birth is also a measure of overall quality of life in a country and summarizes the mortality at all ages. It can also be thought of as indicating the potential return on investment in human capital and is necessary for the calculation of various actuarial measures. |

This entry includes the figure for the difference between the number of persons entering and leaving a country during the year per 1,000 persons (based on midyear population). An excess of persons entering the country is referred to as net immigration (e.g., 3.56 migrants/1,000 population), an excess of persons leaving the country as net emigration (e.g., -9.26 migrants/1,000 population). The net migration rate indicates the contribution of migration to the overall level of population change. High levels of migration can cause problems such as increasing unemployment and potential ethnic strife (if people are coming in) or a reduction in the labor force, perhaps in certain key sectors (if people are leaving). |

For another example, (MonthFn August Year) is equal to August, the class of all months of August. Note that this function returns a Class as a value. The reason for this is that the related functions, viz. DayFn, HourFn, MinuteFn, and SecondFn, are used to generate both specific TimeIntervals and recurrent intervals, and the only way to do this is to make the domains and ranges of these functions classes rather than individuals. |

This average annual percent population change results from a surplus (or deficit) of births over deaths and the balance of migrants entering and leaving a country. The rate may be positive or negative. The growth rate is a factor in determining how great a burden would be imposed on a country by the changing needs of its people for infrastructure (e.g., schools, hospitals, housing, roads), resources (e.g., food, water, electricity), and jobs. Rapid population growth can be seen as threatening by neighboring countries. |
