Anisotropic light propagation in paper

We investigate anisotropic light propagation in paper using both a theoretical model and experiments. The theoretical model utilizes the Monte Carlo method to solve the photon transport equation numerically. It is assumed that wood fibres are represented by infinitely long, homogeneous and straight cylinders. The layer-like microstructure and anisotropic orientation of the fibres is considered ...

Arithmetic without Fear *Abridged.

Now why should such things be ? How can we make the rough places plain and the crooked straight, so that all children may enter into their rightful heritage, that fairyland which the realm of number was to Lewis Carroll or A. A. Milne ? The extent of the Arithmetic phobia is not so widespread as it is usually supposed to be. I have repeatedly found that the majority of small children really do ...

On Generalized Random Railways

We consider a random generalized railway defined as a random 3-regular multigraph where some vertices are regarded as switches not allowing traffic between any pair of attached edges. It is shown that the probability that the generalized railway is functioning is linear in the proportion of switches. Thus there is no threshold phenomenon for this property.

Abridged Petri Nets

A new graphical framework, Abridged Petri Nets (APNs) is introduced for bottom-up modeling of complex stochastic systems. APNs are similar to Stochastic Petri Nets (SPNs) in as much as they both rely on component-based representation of system state space, in contrast to Markov chains that explicitly model the states of an entire system. In both frameworks, so-called tokens (denoted as small ci...
