A fractal model of the cosmos is presented in terms of distinct orders of universes, particles, substrates and strata. Each universe in the fractal cosmos is characterized by the radius of that universe divided by the effective radius of one of its stratum particles. It is shown that this size ratio increases rapidly for higher order universes and that a series of universes of descending order ...

abstract myzus persicae sulzer is one of the serious pests in potato fields which has the ability of transmitting several viruses to the potato crop. throughout summer of 2008, field studies were carried out in ardabil to evaluate the seasonal population fluctuation of this aphid on 10 potato cultivars: granola, satina, moren, aozonia, cosima, agria, cosmos, kondor, diamant and savalan. density...

In recent years the concept of emergence has gained much attention as computer systems have started exhibiting properties usually associated with complex systems. Although emergence creates many problems for engineering complex computerized systems by introducing undesired behaviour, it also offers many possibilities for advancements in the area of adaptive self-organizing systems. However, at ...

We describe an algorithm which automates the generation of appropriate shift and coin operators for a discrete time quantum walk, given the adjacency matrix of the graph over which the walk is run. This gives researchers the freedom to numerically investigate any discrete time quantum walk over graphs of a computationally tractable size by greatly reducing the time required to initialise a give...

The editors of these CoSMoS Workshop Proceedings have invited us to describe the two sides of our joint approach to computer simulation of biological systems: the biological side and the computer science side. Irun Cohen, an immunologist, will voice the biological side; David Harel, a computer scientist, will voice the computer science side.

We describe our use of the CoSMoS process to structure an incremental change of a biological simulation. The domain is auxin transport canalisation. An existing simulator is refactored to handle aspects of 2D and 3D space more efficiently, and enhanced to include more realistically-shaped plant cells. The CoSMoS process supports clear separation of concerns, allowing us to concentrate on the bi...
