A novel reaction-diffusion cellular-automaton model that generates Turing-like spatial patterns is proposed. The model employs linear diffusion fields of activators and inhibitors and a discrete transition rule after diffusion. Theoretical analysis of the one dimensional model proved that i) spatial distribution given by a periodic square function is stable at the equilibrium and ii) the spatia...

in this study, liquid-liquid extraction process in a kuhni extraction column was modeled and simulated. a non-equilibrium dynamic model was developed for modeling liquid-liquid extraction processes based on a rate-based model. the model equations are inclusive of partial and ordinary differential equations which were discretized in column height direction. the population balance model was used ...

This thesis concerns both static and dynamic modeling in a spatial computable general equilibrium setting. First, we have applied a static framework for the assessment of economic impacts of the Öresund bridge. Secondly, we make an attempt to enhance the static framework through the introduction of economic dynamics. In the first paper we study the economic impacts of the Öresund bridge. We aim...

Many studies of metapopulation models assume that spatially extended populations occupy a network of identical habitat patches, each coupled to its nearest neighbouring patches by density-independent dispersal. Much previous work has focused on the temporal stability of spatially homogeneous equilibrium states of the metapopulation, and one of the main predictions of such models is that the sta...

It is well known that if reacting species experience unequal diffusion rates, then dynamics that lead to a constant steady state in a "well-mixed" environment can in a spatial setting lead to interesting patterns. In this paper, we focus on complementary pattern formation mechanisms that operate even when the diffusion rates are equal. In particular, we can say that when the mean-field ODE has ...

In this paper, from the perspective of spatial economics, we studied the spatial spillover of public services and their effect on factor income. We establish a Nonlinear General Equilibrium Model, which contains “two regions, two sectors and two elements". For the determination of the spill-over effect, using Matlab mathematical software to draw a furger, through the mathematical method of deri...

The Dissertation at hand investigates the effects of different policy options on the world sugar market. A Spatial Price Equilibrium Model as suggested by Takayama and Judge is established. This model type has one considerable advantage over previously applied types which is its ability to combine the assumption of homogeneous goods regardless of origin (as opposed to Armington-based models) wi...

We consider the interacting new agegraphic dark energy model to investigate the validity of the generalized second law of thermodynamics in non-flat universe enclosed by the apparent horizon. We show that for this model in presence of interaction with the cold dark matter, the equation of state parameter can cross the phantom divide. We also present that for the selected model under thermal equ...

The paper explores a model of equilibrium selection in coordination games, where agents from an infinite population stochastically adjust their strategies to changes in their local environment. Instead of playing perturbed best-response, it is assumed that agents follow a rule of `switching to better strategies with higher probability'. This behavioral rule is related to bounded-rationality mod...
