Internal Diffusion-Limited Aggregation: Parallel Algorithms and Complexity
Internal diffusion gathered circuit subset the comparator
2014/12/22
The computational complexity of internal diffusion-limited aggregation (DLA) is examined from both a theoretical and a practical point of view. We show that for two or more dimensions, the problem of ...
Coupling the high-complexity land surface model ACASA to the mesoscale model WRF
high-complexity land surface model mesoscale model WRF
2014/12/19
In this study, the Weather Research and Forecasting (WRF) model is coupled with the Advanced Canopy–Atmosphere–Soil Algorithm (ACASA), a high-complexity land surface model. Although WRF is a state-of-...
Scheme for calculation of multi-layer cloudiness and precipitation for climate models of intermediate complexity
multi-layer cloudiness precipitation for climate models intermediate complexity
2014/12/12
In this study we present a scheme for calculating the characteristics of multi-layer cloudiness and precipitation for Earth system models of intermediate complexity (EMICs). This scheme considers thre...
MEDUSA-2.0: an intermediate complexity biogeochemical model of the marine carbon cycle for climate change and ocean acidification studies
MEDUSA-2.0 intermediate complexity biogeochemical model marine carbon cycle climate change ocean acidification studies
2014/12/12
MEDUSA-1.0 (Model of Ecosystem Dynamics, nutrient Utilisation, Sequestration and Acidification) was developed as an "intermediate complexity" plankton ecosystem model to study the biogeochemical respo...
Medusa-1.0: a new intermediate complexity plankton ecosystem model for the global domain
The sea is expected Plankton. Ecosystems The pump The carbon cycle. The terrestrial biosphere
2014/12/9
The ongoing, anthropogenically-driven changes to the global ocean are expected to have significant consequences for plankton ecosystems in the future. Because of the role that plankton play in the oce...
An Integrated and Evolutionary Dynamical Systems View of Climate Complexity
Climate Change Complexity System Earth
2013/3/11
The Earth shows a constant display of an organized complexity system, and its intrinsic capacity for sporadic self-organization constitutes its fundamental and profound mysterious property. A graphica...
On the Complexity of 2D Discrete Fixed Point Problem
Complexity 2D Discrete Fixed Point Problem
2012/12/3
While the 3-dimensional analogue of Sperner’s problem in the plane was known to be complete in class PPAD, the complexity of 2D-SPERNER itself is not known to be PPAD-complete or not. In this paper, w...
Conditional Kolmogorov Complexity and Universal Probability
Conditional Kolmogorov Complexity Universal Probability Information Theory
2012/6/21
The conditional in conditional Kolmogorov complexity commonly is taken to be a finite binary string. The Coding Theorem of L.A. Levin connects unconditional prefix Kolmogorov complexity with the discr...
Topological complexity of motion planning in projective product spaces
Topological complexity product projective spaces Euclidean immersions of manifolds generalized axial maps
2012/6/14
We study Farber's topological complexity (TC) of Davis' projective product spaces (PPS's). We show that, in many non-trivial instances, the TC of PPS's coming from at least two sphere factors is (much...
Absolutely symmetric trees and complexity of natural number
Absolutely symmetric trees complexity of natural number Combinatorics
2012/5/24
We consider the rooted trees which not have isomorphic representation and introduce a conception of complexity a natural number also. The connection between quantity such trees with $n$ edges and a co...

Adaptive Conditional Zero-Forcing Decoder Full-diversity Essentially-ML Performance STBCs
2012/5/24
A low complexity, essentially-ML decoding technique for the Golden code and the 3 antenna Perfect code was introduced by Sirianunpiboon, Howard and Calderbank. Though no theoretical analysis of the de...

2012/5/9
We define and study an equivariant version of Farber's topological complexity for spaces with a given compact group action. This is a special case of the equivariant sectional category of an equivaria...
