Yet, ecologists are usually faced with scarce data and must often make subjective choices about scale.
Consequently, plant managers and engineers are usually faced with important preventive maintenance decisions, which affect plant performance.
In a discrete-event simulation study, we are usually faced with dealing with an extremely large design space in a random environment.
In order to guarantee non-functional properties like scalability or availability, developers are usually faced with the same problems over and over again.
In fact, in practical applications, trying to determine a best flying strategy with the use of optimal approaches, we are usually faced with the problem of a large degree of freedom, which makes the classical analytical and numerical optimization methods ineffective.
Several design methods have been proposed for estimating the magnitude of arching for GRPS embankments, but they are usually faced with two limitations: a pre-set constant critical arch height is assumed for the load calculation, and influences of the membrane effect of deflected geosynthetic and the resistance of compressible subsoil are poorly considered in supporting the embankment fill.
Perhaps this explains the often antagonistic reaction that activists of almost any kind are usually faced with in their bid to uphold citizens' rights in Africa.
For small population risks (the position we are usually faced with), the independence link is closely approximated by the identity link and the log link is closely approximated by the logit link.
For this reason, when creating the mathematical models, researchers are usually faced with the inverse problem when the number of samples or dimensions in the data is smaller than the number of parameters (so-called ill-posed inverse problem).
Malaria control programs are usually faced with uncertainties regarding decisions on whether seasonal preventive measures should be used routinely in areas known to be at risk due to their geographic characteristics or whether developing mechanisms for rapid response is a better strategy.
