The algorithm is developed in the context of the perturbed two body problem, with the secular J4 effect as the only source of perturbation.
Another important result is that the major source of perturbation upon RT communication is caused by the increase of external network load and not by the error-prone characteristics of the wireless medium.
This fear is one source of perturbation (tarakhê), and is a worse curse than physical pain itself; the absence of such fear is ataraxy, lack of perturbation, and ataraxy, together with freedom from physical pain, is one way of specifying the goal of life, for Epicurus.
Such empty fears and desires, based on what Epicurus calls kenodoxia or empty belief, are themselves the main source of perturbation and pain in civilized life, where more elementary dangers have been brought under control, since they are the reason why people are driven to strive for limitless wealth and power, subjecting themselves to the very dangers they imagine they are avoiding.
Monitoring of relevant marker genes will also give an indication as to the source of perturbation.
In a typical MS experiment, there are three main sources of perturbations: random noise, chemical noise and contaminants.
For both plasticity and robustness, there are epigenetic and genetic sources of perturbations to a biological system, which act in different time scales.
Today's integrated circuits are liable to operate under transient faults created either by radiation or malicious sources of perturbation.
From Figure 3 we can also infer that one of the major sources of perturbation upon the RT communication is the increase of the external network load and not only the error-prone characteristics of the wireless medium.
The propagation of a RZ pulse under the action of fiber dispersion, nonlinearity, and various sources of perturbation is represented in terms of a simple set of evolution equations for its parameters.
