Population dynamics survival rates

Such subde effects of the trichome barrier might explain our recent finding that feeding is a much smaller portion of the activity budget of Colorado potato beetle larvae on S. berthaultii than on non-glandular susceptible cultivars (Table V) (34) and thus provide an explanation for several of the major impacts of resistance on this pest, i.e. decreased food consumption leads to the reduced growth rates, retarded development, and their cumulative suppressive effects on survival, fecundity, and population dynamics. 

The Charge Transfer Rate Constant. It is interesting at this point, however, to consider how the dynamics of p(z, t) is related to the usual measure of kinetics, the reaction rate constant. The key quantity to consider is the survival population S(t),... 

The individual optimal maintenance date i,-, and penalty function hi(At) are calculated according to the failure probability function F,(t). This probability function F, (i) is derived from the failure rate function Li(t). This function X,(i) is determined by a survival analysis of component i. It is based on the time-to-failure of a component population and can not be computed for one particular component (Singpurwalla 1995). Although the classical rolling horizon method provides a dynamic maintenance planning to the ciu-rent system (according to the short-term information), this optimization is based on a priori information concerning the reliability properties of components.
