Cube-machining test is a possible method for evaluating the accuracy of five-axis machining centers. Although the geometric errors of rotary axes can be evaluated by measuring the height and inclination errors of the machined surfaces, other error so

En aquest treball s’ha aportat coneixement a la societat d’un dels errors més comuns durant la resolució de problemas matemàtics, com és l’error d’inversió (EI). A més s’ha aportat coneixement a tres grans camps com son la neurociènc
