(a) The LDQ structure of the B 2 H 7 − molecule. The nuclei are as indicated and the electrons are denoted by either dots or crosses, depending on their relative spins. The thick lines denote coincident electron pairs. (b) The traditional valence bond theory structure for the B 2 H 7 − molecule. The horizontal bar stretching across the ...

Also, the vertical symmetry of f is the reason and are identical in this example. In signal processing, cross-correlation is a measure of similarity of two series as a function of the displacement of one relative to the other. This is also known as a sliding dot product or sliding inner-product. It is commonly used for searching a long signal ...
The term "diagram" in its commonly used sense can have a general or specific meaning: visual information device : Like the term "illustration", "diagram" is used as a collective term standing for the whole class of technical genres, including graphs, technical drawings and tables.
For example, the first row of multiplications resulting in e 1 in the above listing is obtained by following the three paths connected to e 1 in the lower Fano diagram: the circular path e 2 × e 4, the diagonal path e 3 × e 7, and the edge path e 6 × e 1 = e 5 rearranged using one of the above identities as:
Also, the dot, cross, and dyadic products can all be expressed in matrix form. Dyadic expressions may closely resemble the matrix equivalents. The dot product of a dyadic with a vector gives another vector, and taking the dot product of this result gives a scalar derived from the dyadic.
