A model of population dynamics - further investigations

چکیده
We present supplementary investigations referring to the model of an evolving population described in Physica A 252 (1998) 325 335. The population is composed of individuals characterised by their genetic strings, phenotypes and ages. We discuss the in uence of probabilities of survival of the individuals on the dynamics and phenotypic variability of the population. We show that constant survival probabilities of individuals are propitious for preserving phenotypic variability of the population. For constant survival probabilities oscillations of 'the average tness' of the population and normal distributions of the phenotypes are observed. When the probabilities of survival are directly proportinal to the individuals' adaptations the population can reach the maximum e-mail: [email protected]

متن کاملPopulation Dynamics of Iran from Sociological Approach
This paper examines intergenerational transmission associated with population dynamics from sociological approach. The discussion is based on the analysis of observations in a country that has experienced substantial changes in family formation resulting in one of the world's most spectacular falls in women's birth rate ever experienced in human history: Iran. Facing fundamental historical expe...
متن کاملStochastic functional population dynamics with jumps
In this paper we use a class of stochastic functional Kolmogorov-type model with jumps to describe the evolutions of population dynamics. By constructing a special Lyapunov function, we show that the stochastic functional differential equation associated with our model admits a unique global solution in the positive orthant, and, by the exponential martingale inequality with jumps, we dis...
متن کاملAn epidemic model for the transmission dynamics of HIV/AIDS with different clinical stages
In this paper, a five–dimensional mathematical model is proposed for the transmission dynamics of HIV/AIDS within a population of varying size. In writing the model, we have divided the population under consideration into five sub classes of susceptible, infective, pre-AIDS, AIDS related complex and that of AIDS patients. The model has two non- negative equilibria namely, a disease free and the...
متن کاملAnalytical and comparative investigations on counter flow heat exchanger using computational fluid dynamics
This paper presents a comprehensive and exclusive thermodynamic analysis of counter flow heat exchanger under various operating and geometrical conditions. Analysis system (ANSYS) workbench 14.0 has been used for computational analysis and comparison with previous literature has been carried out in view of variable temperature and mass flow rate of hot and cold fluids. An analytical and statist...
