The "10" and "20" refer to the fact that the actual distances between adjacent electrodes are either 10% or 20% of the total front–back or right–left distance of the skull. For example, a measurement is taken across the top of the head, from the nasion to inion. Most other common measurements ('landmarking methods') start at one ear and end ...

What is now IPMA was originally created in 1946 as the National Meteorological Service (Serviço Metereológico Nacional, SMN), which centralized the functions of the previous existing meteorological sectorial services (Civil Aviation, Army, Military Aeronautics, Navy and Agriculture) as well as the Azores regional meteorological service and part of the university meteorological institutes.

In ten-dimensional geometry, a rectified 10-cube is a convex uniform 10-polytope, being a rectification of the regular 10-cube. There are 10 rectifications of the 10-cube, with the zeroth being the 10-cube itself. Vertices of the rectified 10-cube are located at the edge-centers of the 10-cube.
In geometry, a 10-demicube or demidekeract is a uniform 10-polytope, constructed from the 10-cube with alternated vertices removed. It is part of a dimensionally infinite family of uniform polytopes called demihypercubes. E. L. Elte identified it in 1912 as a semiregular polytope, labeling it as HM 10 for a ten-dimensional half measure polytope.
The D 10 family has symmetry of order 1,857,945,600 (10 factorial × 2 9). This family has 3×256−1=767 Wythoffian uniform polytopes, generated by marking one or more nodes of the D 10 Coxeter-Dynkin diagram. Of these, 511 (2×256−1) are repeated from the B 10 family and 256 are unique to this family, with 2 listed below. Bowers-style ...
