If {eq}A=\{1,2,3\} {/eq} and {eq}B=\{a, b, c, d\} {/eq}, what is {eq}|P(A \times B)| {/eq}? Power Sets: Given a set {eq}S {/eq}, the power set {eq}P(A) {/eq} is defined to be the set of all subsets of the original set {eq}A {/eq}. In set-...
An easy exclusion criterion is a matrix that is not nxn. Only a square matrices are invertible (have an inverse). For the matrix to be invertible, the vectors (as columns) must be linearly independent. In other words, you have to check that for an nxn ma
In our approach, we first determine a decision boundary that distinguishes between the incurred cognitive loads by one- and two-back auditory tasks on individuals' PFC (acquired by near-infrared spectroscopy (NIRS)). In this task, the participants are instructed to respond (e.g., through mouse...
The hash function H(m) of Tillich and Z´emor [11] is based on the group SL2 (IF2n ): Definition 1. Let A := ( α 1 1 0 ), B := αα+1 11 be elements of SL2 (IF2n ), the group of 2 × 2-matrices with determinant 1 over IF2n . Here α∈ IF2n is a root of...
