The energy consumption from the arc can be reduced if the wire can be fed into the arc region at a higher temperature. That means the arc energy can be used elsewhere, for example for increasing the parent metal melting. (W 81) (1)

Arc energy = Energia de arco

The fundamental theory underlying the algorithms of focal law calculators to focus the sound energy from an array is to ensure that the wave fronts from each element arrive at the target position at the same time (assuming velocity is constant) and in the correct phase to constructively generate a maximum in sound pressure. (W 102) (2)

Sound energy = Energia sonora

The figures compare experimental and simulated results for the load/displacement and load/local strain relationships. The simulated stiffness values of the panels are well predicted, along with the failure loads, which are all within 10% of the average experimental results for each impact energy. (W 11) (3)

Impact energy = Energia de impacto
