Mechanisms and time scales of glacial inception simulated with an Earth system model of intermediate complexity
Mechanisms Milankovitch forcing time scales
2009/12/3
We investigate glacial inception and glacial thresholds in the climate-cryosphere system utilising the Earth system model of intermediate complexity CLIMBER-2, which includes modules for atmosphere, t...
Frustration and disorder in granular media and tectonic blocks:implications for earthquake complexity
granular media tectonic blocks implications for earthquake complexity
2009/11/16
We present exploratory analogies and speculations on the mechanisms underlying the organization of faulting and earthquake in the earth crust. The mechanical properties of the brittle lithosphere at s...
A simple model for the earthquake cycle combining self-organized complexity with critical point behavior
earthquake cycle self-organized complexity critical point behavior
2009/11/12
We have studied a hybrid model combining the forest-fire model with the site-percolation model in order to better understand the earthquake cycle. We consider a square array of sites. At each time ste...
Anisotropic scaling features and complexity in magnetospheric-cusp:a case study
Anisotropic scaling features complexity magnetospheric-cusp
2009/11/11
Magnetospheric cusps are high-latitude regions characterized by a highly turbulent plasma, playing a special role in the solar wind-magnetosphere interaction. Here, using POLAR satellite magnetic fiel...
Complexity and predictability of daily precipitation in a semi-arid region:an application to Ceará,Brazil
Complexity predictability daily precipitation semi-arid region
2009/11/9
Complexity and predictability of daily precipitation in a tropical semi-arid region (Ceará State, Brazil) is assessed by applying entropy concepts. Precipitation regimes in that region depend on sever...
In their position paper entitled "Towards a new, complexity science of learning and education", Jorg et al. (2007) argue that educational research is in crisis. In their opinion, the transdisciplinary...
Effect of Scale on the Complexity of Snowmelt Systems
Effect of Scale Complexity Snowmelt Systems
2009/10/28
During the melt season of 1978, the nature of snow and ice storage, the energy
sources and the stream flow response were investigated at a site, a small-scale
and a meso-scale watershed in the Coast...
Inter-Comparison of two Snow Models with Different Complexity using Data from an Alpine Site
Inter-Comparison Snow Models Alpine Site
2009/10/22
This contribution describes the modelization of the snow cover evolution with the two physically based snow models CROCUS and ESCIMO at the Col de Porte station (1,325 m a.s.l., French Alps) for the ...
On the Complexity of Matroid Isomorphism Problems
On the Complexity of Matroid Isomorphism Problems
2012/12/3
We study the complexity of testing if two given matroids are isomorphic. The problem is easily seen to be in Σp 2 . In the case of linear matroids, which are represented over polynomially growing fiel...
An Intermediate Complexity Climate Model (ICCMp1) based on the GFDL flexible modelling system
Intermediate Complexity Climate Model GFDL flexible modelling system
2010/2/5
An intermediate complexity coupled ocean-atmosphere-land-ice model, based on the Geophysical Fluid Dynamics Laboratory (GFDL) Flexible Modelling System (FMS), has been developed to study mechanisms of...
Comparison of simulated forest soil response to acid deposition reduction with two models of differing complexity
forest soil \acid deposition reduction
2009/6/5
Great effort has been dedicated to developing soil acidification models for use on different scales. This paper focuses on the changes in model performance of a site scale soil acidification model (NU...
Multi-criteria assessment of the Representative Elementary Watershed approach on the Donga catchment (Benin) using a downward approach of model complexity
Representative Elementary Watershed African Multidisciplinary Monsoon Analysis Donga catchment
2009/5/13
This study is part of the AMMA - African Multidisciplinary Monsoon Analysis- project and aims at a better understanding and modelling of the Donga catchment (580 km2, Benin) behaviour in order to dete...
Issues of diffuse pollution model complexity arising from performance benchmarking
diffuse pollution model performance benchmarking
2009/5/6
Flow and nitrate dynamics were simulated in two catchments, the River Aire in northern England and the River Ythan in north-east Scotland. In the case of the Aire, a diffuse pollution model was couple...
Non-locality distillation and post-quantum theories with trivial communication complexity
Non-locality distillation post-quantum theories trivial communication complexity
2010/4/9
We first present a protocol for deterministically distilling non-locality, building upon a recent result of Forster et al. [Phys. Rev. Lett. 102, 120401 (2009)]. Our protocol, which is optimal for two...
Simplicity versus complexity in modelling groundwater recharge in Chalk catchments
Chalk modelling groundwater recharge
2009/3/17
Models of varying complexity are available to provide estimates of recharge in headwater Chalk catchments. Some measure of how estimates vary between different models can help guide the choice of mode...
