由映射定义等价关系(The Equivalence Relation Defined by a Map):任意映射 f:S→T 给出了一个它定义域 S 上的等价关系:若 f(a)=f(b) ,则 a∼b。f−1(t) 叫做t 的原像(inverse image),也叫 fibres of the map f,表示像为 t 的所有自变量的集合(这只是一个符号表示(symbolic notation),因为...
A commonly known example of symmetric relation is the relationship of biological siblings. If person X is a biological sibling to person Y, then Y is also the biological sibling of X. This is called the “is a biological sibling” symmetric relation. The “is equal to” relation is a symm...
Mass Energy Equivalence Elastic and Inelastic Collisions Law of Conservation of Mass Work FAQs What is the relation between work and power? Power is defined as the rate of work done. Mathematically, it can be stated as Is work a vector? No, work is a scalar quantity. Is negative work poss...
relations represent the connection between the two presented sets. Additionally, there are types of relations like empty relation, universal relation, identity relation, inverse relation, reflexive relation, symmetric relation, transitive relation, and equivalence relation stating the relationships between the...
This logic characterises a process equivalence called quasi-open bisimilarity that has the following desirable properties. The main result of this work is the expressive completeness of our intuitionistic modal logic for a large class of protocols, i.e., whenever there is no proof that a property...
The transfer function defines the relation between the output and the input of a dynamic system, written in complex form (s variable). For a dynamic system with an input u(t) and an output y(t), the transfer function H(s) is the ratio between the complex representation (s variable) of...

Benztropine has not been reported to cause serum aminotransferase elevations, but it has not been evaluated for effects on serum enzyme levels in a prospective manner. Despite its use for more than 50 years, there have been no reports of benztropine liver injury in the literature and it must ...
On the other hand, we are interested in points u^ such that their equivalence class on the torus is fixed by a non-trivial element of the Weyl group, w⋅[u^]=[u^]. In this case, for each w we can always identify (at least) one root α^ such that sα^[u^]=[u^], and ...
For bonds, yield can be analyzed as either cost yield or current yield. Cost yield measures the returns as a percentage of the original price of the bond, while current yield is measured in relation to the current price. What Is an Example of Yield?
