Dynamic model abstraction [PDF]

open access: yesProceedings of the 28th conference on Winter simulation - WSC '96, 1996
While complex behavior can be generated through simple systems, as in chaotic and nonlinear systems, complex systems axe found where a systems study contains multiple physical objects and interactions. Through the use of hierarchy, we are able to simplify and organize the complex system.

Modeling Blog Dynamics

open access: yesProceedings of the International AAAI Conference on Web and Social Media, 2009
How do blogs produce posts? What local, underlying mechanisms lead to the bursty temporal behaviors observed in blog networks? Earlier work analyzed network patterns of blogs and found that blog behavior is bursty and often follows power laws in both topological and temporal characteristics. However, no intuitive and realistic model has

Influence of Surface Reflection (Albedo) in Simulating the Sun Drying of Paddy Rice

open access: yesApplied Sciences, 2020
The sun drying of agricultural products is a complicated process involving heat transfer, mass transfer, and variable weather conditions. Surface reflection (albedo), a crop’s radiative property, plays an essential role in energy balance, and ...

Drought-Induced Amplification of Saint Louis encephalitis virus, Florida

open access: yesEmerging Infectious Diseases, 2002
We used a dynamic hydrology model to simulate water table depth (WTD) and quantify the relationship between Saint Louis encephalitis virus (SLEV) transmission and hydrologic conditions in Indian River County, Florida, from 1986 through 1991, a period ...

Dynamic modelling with events [PDF]

open access: yes, 1994
This paper focusses on the behavioural aspects of the IFO23 model, an extension of the semantic model IFO defined by S. Abiteboul and R. Hull. Its originality is in the formalization of complex events and their specification, which adopts semantics and syntax indentical to those of the structural part.
