When once the engine shall have been constructed, the difficulty shall ha1)e been reduced to the making out of cards; but as these are merely the translation of algebraical formulae, it will, by means of some simple notations, be easy to consign the execution of them to a workman. Thus, the whole intellectual labour will be limited to the preparation of the formulae, which must be adapted f...

The problem of quantifier elimination of positive semidefinite cyclic ternary quartic forms is studied in this paper. We solve the problem by function RealTriangularize in Maple15, the theory of complete discrimination systems and the so-called Criterions on Equality of Symmetric Inequalities method. The equivalent simple quantifier-free formula is proposed, which is difficult to obtain automat...

CCE consists of measuring monitors' daily activities in a specified field and in-depth interviews using the recorded videos afterward. However, privacy issues ...
