Basic ingredients for mathematical modeling of tumor growth in vitro: Cooperative effects and search for space
(2013-11-01)
Based on the literature data from HT-29 cell monolayers, we develop a model for its growth, analogous to an epidemic model, mixing local and global interactions. First, we propose and solve a deterministic equation for the ...

A model for defect formation in materials exposed to radiation
(2021-01-01)
A simple model for the stochastic evolution of defects in a material under irradiation is presented. Using the master-equation formalism, we derive an expression for the average number of defects in terms of the power flux ...

Dynamic reduced model and stochastic aspects for PFGM curved beams with variable curvature
(Pergamon-Elsevier Science Ltd, 2021-01)
In this paper a new 1D finite element model for dynamic calculations of PGFM curved beams with variable curvature is developed. The reduced high-speed calculation model allows stochastic aspects in the dynamic of the ...
Stochastic field processes in the mathematical modelling of damped transmission line vibrations
(1987-12-01)
Wind-excited vibrations in the frequency range of 10 to 50 Hz due to vortex shedding often cause fatigue failures in the cables of overhead transmission lines. Damping devices, such as the Stockbridge dampers, have been ...

Modifying the stochastic model to mitigate GPS systematic errors in relative positioning
(2007-12-01)
The GPS observables are subject to several errors. Among them, the systematic ones have great impact, because they degrade the accuracy of the accomplished positioning. These errors are those related, mainly, to GPS ...
Accounting for climate change in a forest planning stochastic optimization model
(Canadian Science, 2016)
An approach is proposed for incorporating the variations in timber growth and yield due to climate change uncertainty into the forest harvesting decision process. A range of possible climate scenarios are transformed by a ...
Markovian versus non-Markovian stochastic quantization of a complex-action model
(World Scientific Publ Co Pte Ltd, 2014-03-10)
We analyze the Markovian and non-Markovian stochastic quantization methods for a complex action quantum mechanical model analog to Maxwell-Chern-Simons electrodynamics in Weyl gauge. We show through analytical methods ...
