Rapid urban growth in the city of Duhok, Iraqi Kurdistan Region: An integrated approach of GIS, Remote Sensing and Shannon Entropy application
GIS remote sensing Landsat TM Urban sprawl Shannon entropy
2014/11/17
Duhok, a mountainous city in Kurdistan Region of Iraq, has witnessed rapid urban growth over
the past decade due to population growth and economic improvements. These factors have
placed a great p...
An information entropy approach to salience for survey-driven simulation
An information entropy approach to salience survey-driven simulation
2014/8/8
Interpreting a 2010 survey of Houston-area households subject to hurricane Ike in 2008, the di culty in inferring ex-ante preferences from ex-post survey responses is exacerbated by many of the respon...
Acyclic edge-coloring using entropy compression
Acyclic edge-coloring entropy compression Combinatorics
2012/6/29
An edge-coloring of a graph G is acyclic if it is a proper edge-coloring of G and every cycle contains at least three colors. We prove that every graph with maximum degree Delta has an acyclic edge-co...
Lowering topological entropy over subsets revisited
entropy principal extension lowerable hereditarily lowerable
2012/6/19
Let $(X, T)$ be a topological dynamical system. Denote by $h (T, K)$ and $h^B (T, K)$ the covering entropy and dimensional entropy of $K\subseteq X$, respectively. $(X, T)$ is called D-{\it lowerable}...
Sumset and Inverse Sumset Inequalities for Differential Entropy and Mutual Information
Shannon entropy differential entropy sumset bounds inequalities submodularity data processing mutual information
2012/6/19
The sumset and inverse sumset theories of Freiman, Pl\"{u}nnecke and Ruzsa, give bounds connecting the cardinality of the sumset $A+B=\{a+b\;;\;a\in A,\,b\in B\}$ of two discrete sets $A,B$, to the ca...
A comment on the relation between diffraction and entropy
relation between diffraction and entropy Mathematical Physics
2012/5/24
Diffraction methods are used to detect atomic order in solids. While uniquely ergodic systems with pure point diffraction have zero entropy, the relation between diffraction and entropy is not as stra...
Quantifying Selection and Diversity in Viruses by Entropy Methods, with Application to the Hemagglutinin of H3N2 Influenza
Quantifying Selection and Diversity Viruses Entropy Methods Hemagglutinin of H3N2 Influenza Populations and Evolution
2012/5/2
Many viruses evolve rapidly. For example, hemagglutinin of the H3N2 influenza A virus evolves to escape antibody binding. This evolution of the H3N2 virus means that people who have previously been ex...
Improving the Entropy Estimate of Neuronal Firings of Modeled Cochlear Nucleus Neurons
Entropy Estimate Neuronal Firings Modeled Cochlear Nucleus Neurons Neurons and Cognition
2012/5/2
In this correspondence information theoretical tools are used to investigate the statistical properties of modeled cochlear nucleus globular bushy cell spike trains. The firing patterns are obtained f...
Entropy, Lyapunov exponents and the volume growth of boundary distortion under the action of dynamical systems
Lyapunov exponents the volume growth of boundary distortion the action of dynamical systems
2012/4/17
We study the connection between the Lyapunov exponents and the volume growth of boundary distortion of regions in the phase space of the dynamical system.
R\'enyi entropy of order \alpha is a general measure of entropy. In this paper we derive estimations for the R\'enyi entropy of the mixture of sources in terms of the entropy of the single sources. Th...
Bayesian interpretation of Generalized empirical likelihood by maximum entropy
Bayesian interpretation Generalized empirical likelihood maximum entropy
2012/3/1
We study a parametric estimation problem related to moment condition models. As an alternative to the generalized empirical likelihood (GEL) and the generalized method of moments (GMM), a Bayesian app...
Entropy-Enthalpy Compensation May Be a Useful Interpretation Tool for Complex Systems Like Protein-DNA Complexes: An Appeal to Experimentalists
Entropy-Enthalpy Compensation Useful Interpretation Tool Complex Systems Protein-DNA Complexes Experimentalists
2012/2/28
In various chemical systems enthalpy-entropy compensation (EEC) is a well-known rule of behavior, although the physical roots of it are still not completely understood. It has been frequently question...

This paper is aimed at developing a better understanding of the structure of the information that in contained in galaxy surveys, so as to find optimal ways to combine observables from such surveys. W...
Explicit Bounds for Entropy Concentration under Linear Constraints
maximum entropy concentration bounds linear constraints tolerances
2011/9/23
Abstract: Consider the construction of an object composed of $m$ parts by distributing $n$ units to those parts. For example, say we are assigning $n$ balls to $m$ boxes. Each assignment results in a ...
