They are capable of generating of continuous tractive effort. This assumption is largely valid for either continuous or batch manufacturing processes. This substantially unifies the treatment of discrete and continuous probability distributions. Hybrid systems allow for time domains that have both continuous and discrete parts. The definition generalizes to a mixture of arbitrary numbers of discrete and continuous random variables. Aerogel composites have been made using a variety of continuous and discontinuous reinforcements. Processes can be characterized as batch, continuous, or hybrid. A triathlon is a multisport race with three continuous and sequential endurance races. Compound locomotives were especially useful in trains where long periods of continuous efforts were needed. Shortwave diathermy can be applied in either continuous or pulsed mode. Spearman's coefficient is appropriate for both continuous and discrete ordinal variables. Hearsay I was one of the first systems capable of continuous speech recognition. The same proof is also applicable for samples taken from a continuous probability distribution. The space of continuous and compactly supported functions is dense in . SOTDMA is used by mobile devices operating in autonomous and continuous mode.
