The structure of the shallow subsurface (regolith) represents the least well known variable.
The control law, which is able to regulate and to track the desired reference signals, is designed using the well known variable structure theory.
Gutjahr et al. [23] recently introduced a stochastic variant of the well known variable neighborhood search (VNS, [24]) for project portfolio analysis under uncertainty.
They must, of course, take into account as precisely as possible levels of entropy and redundancy as well as other known variables.
It is well known that variable selection can be a useful tool for optimising multivariate prediction models, since many of the detected variables (in this case, metabolites) carry no systematic information about the health status of the individual [ 28]; that is, they are the same in RA patients as in controls and only introduce noise in the model.
Fixed rate results are not given here due to space limitations, and since it is well known that variable rate coding is more efficient than fixed rate in terms of LSD.
There is a simple rationale for monitoring a well known physiologic variable as a way to solve the problem, and a safe and effective device is available to carry out the function.
Although it is well known that variable selection has several difficulties (Sauerbrei, 1999; Harrell, 2001), these strategies are often required to derive a sensible, interpretable, and parsimonious model (Sauerbrei, 1999; Royston and Sauerbrei, 2008).
The authors believe that, due to its transparency and clear link to well known parameters and variables, the linearised core propulsion system model as derived in this paper should appeal to marine system engineers, control engineers and hydrodynamicists alike.
It is well known that correlated variables can diminish the predicting power of the model and thus we must understand the explanatory power between them first in order to construct a statistical significant model.
To reduce the exhaust gas emissions, many efforts have been carried out to reformulate fuels and design new catalytic converters; however, it is well known that other variables such as socio-economic and transport structure factors also play an important role around this problem.
