The main purpose of the paper is to calculate the magnetic force delivered by actuators with a nonmagnetic body levitated in a ferrofluid that is magnetized by permanent magnets. A linear algebraic formula is proposed for this purpose, which is then

In spite of a relatively great variety of theoretical approaches to translation, translation theory mainly deals, irrespective of how elaborate it is, with fidelity to either the letter or the spirit of a message. The former type is described accordi
