Group orderA group is finite if its set contains only a finite number of elements. The number of elements is then called the order of the group. If \(\mathbb{G}\) is the set of the group, its order is usually written as \(|\mathbb{G}|\), which is the same notation as used ...
The K-technique, which can be best explained in terms of rewriting modulo equations or in terms of rewriting logic, is based on a first-order ... G Rosu 被引量: 16发表: 2005年 Vector Logic: A Natural Algebraic Representation of the Fundamental Logical Gates rewrite-based theorem-provingsati...
Welcome to Explained from First Principles, a technology, science, and philosophy blog for curious people who want to understand and change the world. In order to make you feel at home here as quickly as possible, here is what you should know about this blog. ...
This can be explained by noticing that observations of congestion of pedestrian traffic over the total width of the cross section do not belong to a single fundamental diagram but belong to a set of different fundamental diagrams. This observation has consequences for estimation of the fundamental ...
In the previous sections, the basics of differential equations have been explained, including first order differential equations. In this section, we take the study a bit further to look at the second-order differential equations, which are equations that contain the second derivative of the dependa...

The fact that life fits comfortably with (and indeed, is explained by) the Second Law still begs the question of how this relates to the order and complex organization of living systems. In turning to this question, we introduce another key concept:information. ...
Acting upon target stimuli from the environment becomes faster when the targets are preceded by a warning (alerting) cue. Accordingly, alerting is often used to support action in safety-critical contexts (e.g., honking to alert others of a traffic situat
For practical reasons, we have to rely on a finite set of symbols to represent an infinite set of numbers. To make this possible, we have to assign meaning to the order, position, and/or repetition of symbols. With the exception of tally marks, only the positional notation is relevant ...
