چکیده

A study is made of an overtaking optimal problem for a population system consisting of two competing species, which is controlled by fertilities. The existence of optimal policy is proved and a maximum principle is carefully derived under less restrictive conditions. Weak and strong turnpike properties of optimal trajectories are established. © 2007 Elsevier Inc. All rights reserved.

Effect of Infant Prematurity on Auditory Brainstem Response at Preschool Age

Introduction: Preterm birth is a risk factor for a number of conditions that requires comprehensive examination. Our study was designed to investigate the impact of preterm birth on the processing of auditory stimuli and brain structures at the brainstem level at a preschool age.   Materials and Methods: An auditory brainstem response (ABR) test was performed with low rates of stimuli in 60 ch...

The effect of age on the mating competitiveness of male Glossina fuscipes fuscipes and G. palpalis palpalis

The effect of age on male Glossina fuscipes fuscipes, Newstead, and Glossina palpalis palpalis, Austin (Diptera: Glossinidae) competiveness were investigated with a view to estimate optimal age for sterile male release. Sterile insect technique involves the mass production, sterilization and sequential release of males of the target species to out compete the wild male population. Mating betwee...

Optimal Location and Parameter Settings of UPFC Device in Transmission System based on Imperialistic Competitive Algorithm

In this paper, we present a new method to determine the optimal location and parameter settings of UnifiedPower Flow Controller (UPFC) for removing voltage violations and transmission lines overloading. UPFC isconsidered as the most powerful member of the FACTS devices, that it can control shunt and series power flow.This option gives to UPFC the power to control the voltage profile and transmi...

Competitive intransitivity and size-frequency distributions of interacting populations.

The competitive ranking of three marine sessile organisms was determined from overgrowth observations and found to be intrasitive. Overgrowth results were dependent upon relative vertical relief which, in turn, was related to colony area. Discriminant function analysis demonstrates that competitive rankings can be largely predicted on the basis of knowledge of the size-frequency distribution of...

Optimal Birth Control for an Age-dependent N-dimensional Food Chain Model Ii. Free Horizon Problems

We study optimal birth policies for an age-dependent n-dimensional food chain model, which is controlled by fertility. New results on problems with free final time and integral phase constraints are presented, the approximate controllability of system is discussed.
