Sigma KEE - EFScaleAttribute

EFScaleAttribute(enhanced fuijita scale attribute)

appearance as argument number 1

(documentation EFScaleAttribute ChineseLanguage "EFScaleAttribute 是改良藤田级数的简称。这是根据一系列龙卷风所造成的损害，估计首灾区的3秒阵风风速来表示一个 Tornado (龙卷风)的强度。级数最低的龙卷风为 EFO，它的阵风风速估计在 65 到 85 mph 之间，而最强级别的 Tornades 是 EF5，阵风大于 GreaterThan 200 mph。")	Weather.kif 2080-2082
(documentation EFScaleAttribute EnglishLanguage "EFScaleAttribute is short for the Enhanced Fujita Scale. It is the Attribute for indicating the intensity of a Tornado according to a set of 3-second gusts wind estimates based on damage it caused. The lightest tornados(EFO) have wind gusts ranging between 65 to 85 mph,and the severest Tornades (EF5) GreaterThan 200 mph.")	Weather.kif 2075-2079
(subclass EFScaleAttribute SpeedScaleAttribute)	Weather.kif 2084-2084	Enhanced fuijita scale attribute is a subclass of speed scale attribute

antecedent

(=> (and (instance ?EF EFScaleAttribute) (property ?T ?EF)) (instance ?T Tornado))	Weather.kif 2086-2090	If an attribute is an instance of enhanced fuijita scale attribute and an entity the attribute the attribute, then the entity is an instance of tornado
(=> (and (instance ?T Tornado) (instance ?EF EFScaleAttribute) (eventLocated ?T ?AREA) (believes ?A (property ?T ?EF)) (speedScaleAttributeMinMax ?EF (MeasureFn ?MIN MilesPerHour) (MeasureFn ?MAX MilesPerHour))) (exists (?GUST) (and (greaterThanOrEqualTo ?GUST ?MIN) (lessThanOrEqualTo ?GUST ?MAX) (believes ?A (equal (MeasureFn ?GUST MilesPerHour) (ThreeSecondGustSpeedFn ?AREA (WhenFn ?T)))))))	Weather.kif 2092-2110	If a process is an instance of tornado and a speed scale attribute is an instance of enhanced fuijita scale attribute and the process is located at an object and a cognitive agent believes the process the attribute the speed scale attribute and a real number miles per hour(s) and another real number miles per hour(s) are the min and max speed of the speed scale attribute, then there exists a third real number such that the third real number is greater than or equal to the real number and the third real number is less than or equal to the other real number and the cognitive agent believes the third real number miles per hour(s) is equal to ThreeSecondSpeedGustFn ending at the time of existence of the process in the object
