We study the transition from stochasticity to determinism in calcium oscillations via diffusive coupling of individual cells that are modeled by stochastic simulations of the governing reaction-diffusion equations. As expected, the stochastic solutions gradually converge to their deterministic...

<p>In the theory of economics most models describing economic growth make use of differential equations. The examples are Solow's and Haavelmo's models. However, when they are used by econometricians many questions arise. Firstly, economic data are presented in discrete form, which implies the use...</p>

A dome-covered house is an example of designing sustainable buildings by learning from the optimized biological forms from the nature. The paper presents a 3-D thermal and air flow (3D-TAF) model that estimates the energy needs of a dome-covered house. The model is verified with CFD simulations...

This study analyzes classrooms, built according to a standard project of public schools in the Brazilian State of Paraná, concerning their luminic qualities. The daylighting analysis was based on computational simulations with daylighting programs, for different combinations of days, schedules...

The haploid–diploid cycle where, under unfavorable conditions the population becomes diploid, is modeled by a Monte-Carlo method in the framework of the Jan–Stauffer–Moseley hypothesis. Diploidy and sex may have first arisen as a way to escape death, when a simple unicellular individual is...

Using the "meme" conception (Dawkins 1976) of cultural transmission and computer simulations, an exploration is made of the relationship between agents, their beliefs about their environment, communication of those beliefs, and the global behaviours that emerge in a simple artificial society....

In diesem Beitrag stellen wir ein Konzept greifbarer, gegenständlicher Benutzungsschnittstellen vor. Es werdenÜbergänge zwischen dem Modellieren im Realen und dem Erstellen virtueller Modelle geschaffen. Synchronzum gegenständlichen Modell entsteht ein virtuelles Abbild, das für Simulation,...

This report describes the NETCELL simulation package. NETCELL is a freeway network simulation program based on the cell transmission model which captures the dynamic evolution of multicommodity traffic over a freeway network with three-legged junctions in a way that is consistent with the...
