Epidemics on a stochastic model of temporal network
Epidemics stochastic model of temporal network Populations and Evolution
2012/5/2
Contacts between individuals serve as pathways where infections may propagate. These contact patterns can be represented by network structures. Static structures have been the common modeling paradigm...
Infinite-Period Phase Transition versus Nucleation in a Stochastic Model of Collective Oscillations
Infinite-Period Phase Transition Collective Oscillations
2011/9/2
A lattice model of three-state stochastic phase-coupled oscillators has been shown by Wood et al. [Phys. Rev. Lett. 96, 145701 (2006)] to exhibit a phase transition at a critical value of the coupling...

Infinite-Period Phase Transition versus Nucleation Stochastic Model Collective Oscillations
2011/7/7
A lattice model of three-state stochastic phase-coupled oscillators has been shown by Wood et al. [Phys. Rev. Lett. 96, 145701 (2006)] to exhibit a phase transition at a critical value of the coupling...
Self-Consistent Stochastic Model Errors in Data Assimilation
37-XX 37-XX 37-XX 86-XX 86-08 46N55
2010/12/28
In using data assimilation to import information from observations to estimate parameters
and state variables of a model, one must assume a distribution for the noise in the measure-
ments and in th...
A stochastic model for the expected time to recruitment in a two grade manpower system having correlated inter-decision times and constant combined thresholds
Manpower planning Univariate recruitment policy
2010/11/1
In this paper, an organization having two grades in which depletion of manpower occurs at every decision epoch is considered. Using univariate max policy of recruitment, based on shock model approach ...
Unique equilibria and substitution effects in a stochastic model of the marriage market
Unique equilibria substitution effects stochastic model marriage market
2011/1/19
Choo-Siow (2006) propose a very general model for the marriage market which allows for randomly identically distributed noise in the preferences of each of the participants. The randomness is McFadden...
A general stochastic model for sporophytic self-incompatibility
stochastic model sporophytic self-incompatibility
2010/11/15
Disentangling the processes leading populations to extinction is a major topic in ecology and conservation biology. The difficulty to find a mate in many species is one of these processes. Here, we in...
Nonlinear Stochastic Model of Return matching to the data of New York and Vilnius Stock Exchanges
Nonlinear Stochastic Model Return matching Vilnius Stock Exchanges
2010/4/27
We scale and analyze the empirical data of return from New York and Vilnius stock exchanges matching it to the same nonlinear double stochastic model of return in financial market.
Shallow seismicity in the area of Greece:its character as seen by means of a stochastic model
Shallow seismicity area of Greece means of a stochastic model
2009/11/16
Occurrence of successive earthquake events in space is analysed by means of semi-stochastic processes. The analysis employs earthquakes events with M > 5.2 from the area of Greece and its surroundings...
In this paper a mathematical model for the movement of water particles
in a river is constructed.
Using the model it will be possible to find an analytic expression for the
distribution function F(...
Transformation of Input to a Stochastic Model using a Distributed Deterministic Model
Transformation of Input Stochastic Model Distributed Deterministic Model
2009/10/27
In recent years, hydrologists have attempted, with encouraging results, to
synthesize the accomplishments of time series analysis and deterministic systems
methods into the more general framework of...
A STOCHASTIC MODEL FOR IDENTIFICATION OF TRENDS IN OBSERVED HYDROLOGICAL AND METEOROLOGICAL DATA DUE TO CLIMATE CHANGE IN WATERSHEDS
climate change STOCHASTIC MODEL natural processes
2009/10/12
The development of appropriate public policy responses to the impact of climate change on the overall ecosystem would require knowledge of future trends in the natural processes affecting the ecosyste...
Rainfall nowcasting by at site stochastic model P.R.A.I.S.E.
Rainfall Prediction of Rainfall Amount Inside Storm Events stochastic model
2009/5/8
The paper introduces a stochastic model to forecast rainfall heights at site: the P.R.A.I.S.E. model (Prediction of Rainfall Amount Inside Storm Events). PRAISE is based on the assumption that the rai...
A stochastic model of throughfall for extreme events
canopy interception throughfall stochastic rainfall modelling rainfall intensity linear systems landslides
2009/3/3
Although it is well known that forest canopies reduce the amount and intensity of precipitation at the ground surface, little is known about how canopy interception modifies extreme events.
A Lagrangian Stochastic Model for the concentration fluctuations
Lagrangian Stochastic Model concentration fluctuations
2009/2/17
A Lagrangian Stochastic Model for the two-particles dispersion, aiming at simulating the pollutant concentration fluctuations, is presented. Three model versions (1-D, 2-D and 3-D) are tested. Firstl...
