Most of the several dozen people who have tried my Rift put the goggles on as skeptics, but removed them as believers that virtual reality, as a practical phenomenon, now exists.
Since the ATDs subject to uncertain transition probabilities (TPs) are taking into account in a practical phenomenon, new approaches are introduced to deal with the ATDs characterized by nonhomogeneous Markov processes.
Yet his method is ingenious: by interpreting visual media and practical phenomena in terms of linguistics, he appropriates them for language itself; by making linguistics the basis of a sociopolitical analyses of the world, he defines the very production of analysis as a radically progressive act.
In order to better model some complicated practical phenomena, recently, distributed time delay has been introduced into many modeling systems.
This means that biological environment without predator is unstable in nature, which is in good agreement with some practical phenomena.
We illustrate this by some practical phenomena as follows: long-range correlations, lack of scale invariance, discontinuity of the trajectories and so on [1, 2].
Fractional differential equations have received considerable attentions during the past few decades because they are useful for modeling many practical phenomena.
Delay differential equations play an important role in the mathematical modelling of various practical phenomena in the biosciences and control theory.
To emphasize gear fault symptoms caused by tooth pitting, this model ignored transmission errors, the frictions between gear teeth, and other practical phenomena, such as backlash.
These findings demonstrate that the multiscale analysis is not only useful but also necessary in the understanding of practical phenomena involving molecular forces.
Such problems arise in the mathematical modeling of various practical phenomena, for example, in population dynamics [4], the study of bistable devices [5], description of the human pupil-light reflex [6], and variational problems in control theory [7].
