Population 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 کاملModelling Population Dynamics in Realistic Landscapes with Linear Elements: A Mechanistic-Statistical Reaction-Diffusion Approach
We propose and develop a general approach based on reaction-diffusion equations for modelling a species dynamics in a realistic two-dimensional (2D) landscape crossed by linear one-dimensional (1D) corridors, such as roads, hedgerows or rivers. Our approach is based on a hybrid "2D/1D model", i.e, a system of 2D and 1D reaction-diffusion equations with homogeneous coefficients, in which each eq...
متن کاملStatistical Modelling of Population Evolution
In this thesis analytical and simulation techniques are applied to problems in biological evolution. The thesis is divided into four parts. Firstly, chapter two investigates anomalies that occur in the Penna bit-string model of ageing, an influential model of mutation accumulation and selection. These anomalies result in unusual demographic distributions and can lead to the so-called Eve effect...
متن کاملa dynamic modelling for decreasing of loss time average in insurance companies: system dynamics approach
one of the most challenging problems in our country insurance industry is the phenomenon of increase of loss pay average time by insurance companies. a lot of research and analysis have been conducted on both the roots and possible solutions for this problem, none of which has had success in annihilating it. this paper presents a discrete model ) nonlinear mathematical model ( of insurance serv...
متن کاملProduction Constraints Modelling: A Tactical Review Approach
A constraint is a limitation or a restriction that poses a threat to the performance and efficiency of a system. This paper presented a tactical review approach to production constraints modeling. It discussed the theory of constraints (TOC) as a thinking process and continuous improvement strategy to curtail constraints in other to constantly increase the performance and efficiency of a system...
