The problem with SFV is that it reduces the variable charge to short-term variable cost, leading to overconsumption.
For this reason we considered only the long-term variable costs (personnel, depreciation, maintenance) besides the difference between the short-term variable costs [22].
For further details please refer to the Appendix A. Further, we used a short-term variable FLIP, measuring a change of strategic directions between a focal serial acquisition and the previous serial acquisition.
We have designed a juvenile short-term variable stressor protocol [20] in which rats were exposed to a different stressor every day for three days (see below).
Since all variables now depend on τ, there are no more short-term variables dependent on t and, hence, there is no need to compute the user scheduling together with user association as the output of the optimization problem.
All countries show overall cost savings in the short term with variable peaks (shown in bold).
Adrenaline has been shown to improve short term clinical variables, but its effect on admission rates was unclear, mostly due to underpowered studies.
The influence of predictive variables on short term mortality (dependent variable = vital status at 90 days) was evaluated by computing the Odds Ratio (OR) with 95% Confidence Intervals (CI).
By controlling for background seasonality and other nuisance variables, these models estimate the short term effects of variables of interest (weather, immunity and virus evolution).
Animal position and activity is known to affect pooling of gas in the rumen (McCauley and Dziuk, 1965), and pooling of gas in the rumen may be part of the reason that variable short term CH4 production rates are seen during RC studies even from animals fed at 2 h intervals (e.g. Figure 1a: Nolan et al., 2010; Figure 1b: Mathers and Walters, 1982).
These treatments also caused a favorable change in the short term in the chemical variables related to saline-sodic soils, which was seen in the decrease of the EC, SAR and ESP.
