Dynamiczna Psychologia Społeczna
W istniejącym już od ponad 20 lat "Ośrodku badania układów złożonych i nowych technologii" w Instytucie Studiów Społecznych UW, zajmujemy się zastosowaniami teorii układów złożonych i informatyki w psychologii społecznej (dział ten bywa nazywany "dynamiczną …

Numerical methods for the dynamics of the populations with structure
In many situations the description of the dynamics of a population requires taking into account its structure. In the case of one real structural parameter, like the age or size of an individual, nonlinear first …

From Individual to Collective Dynamics in Argentine Ants
Social insects are an important example of complex collective behavior. In particular, ant colonies develop different tasks as foraging, building and allocation [1]. While they search for food they deposit a pheromone that it is …

On the distance between adjacent zeros of solutions of first order differential equation with distributed delays
The results of many publications that estimated the upper bound of the distance between adjacent zeros of any solution of first order delay differential equation will be displayed. We show some fundamental results for the …

Asymptotyka rozwiązań w modelach populacyjnych o strukturze cech fizjologicznych z dyfuzją
Badamy model ewolucyjny uwzględniający śmiertelność, wzrost, narodziny i dyfuzję z warunkami brzegowymi Fellera. Rozpoczynamy rozważania od zasady maksimum, następnie analizujemy rozwiązania rozwijane w szereg Fouriera w przestrzeni Hilberta, która wyznaczona jest przez warunki Fellera. Struktura …

Computational analysis of multi-stable signalling biochemical networks
In this talk, two novel approaches to investigate systemic properties of signalling biochemical networks will be introduced. The first approach focuses on the analysis of information processing in signalling networks performed by the application of …

Structural sensitivity analysis of mathematical models in biology
Sensitivity analysis plays very important and useful role during modeling and analysis of dynamical systems. It answers the question how changes in model parameters affects the model solution. The answer to this question can be …

General model of a cascade of reactions with time delays: global stability analysis c.d.
I discuss a general model of a cascade of reactions with discrete as well as distributed delays, which arose in the context of Hes1 gene expression. For the abstract general model sufficient conditions for global …

Matematyczne modele transportu w czasie dializy otrzewnowej
Modele opisują procesy wymiany płynu i substancji pomiędzy tkanką a:1) krwią przepływającą przez naczynia włosowate zawarte w tkance, oraz 2) otoczeniem tkanki (np. płynem dializacyjnym w jamie otrzewnowej lub żelem nałożonym na powierzchnię skóry). Modele …

Large Scale Parallel Simulations of 3-D Cell Colony Dynamics
Biological processes are inherentlyvery complex and involve many unknown relationships and mechanisms at different scales. Despite many efforts, one still cannot explain all the observed phenomena and, if necessary, make any desirable changes in the …

Pulse wave propagation models
During the seminar I will present the state of the art of mathematical methods utilized in the modeling of the pulse wave propagation (PWP) through the arterial tree. In the spatially distributed approach, the whole …

Phenotypic evolution of hermaphrodites
We consider finite, phenotype-structured population of hermaphrodites, and build an individual based model which describes interactions between the individuals. The model contains such elements as mating of individuals (random or assortative), inheritance of phenotypic traits …
