Many examples of complex systems are provided by applications in finance and economics areas. Some of intrinsic features of such systems lie with the fact that their parts are interacting in a non-trivial dynamic manner and they can be subject to stochastic forces and jumps. The mathematical models for such systems are often based on stochastic differential equations and efficient computational...

A new fusion–evaporation model LisFus for fast calculation of fusion residue cross-sections has been developed in the framework of the code LISE. This model can calculate very small cross-sections quickly due to its compared to programs using the Monte-Carlo method. Such type of fast calculations is necessary to estimate fusion residue yields. Using this model the program LISE has now the possi...

Small-world networks have become an important model for understanding many complex phenomena in science and in sociological contexts. One tool for exploring the critical and phase transitional behaviour in small-world systems is to simulate known models on grids and networks that have been re-wired using the small-world approach. A well known model for studying phase transitions is the Ising sp...

We introduce a fast and well-structured package for constructing voxel-based computational phantoms as MCNP(X) input file based on CT DICOM images. Our program which has been implemented under a graphic user inter-face provides several basic image processing tools for manipulating images. The MCNP materials are interpreted from the CT numbers of DICOM images. Two modes of phantom creation have ...
