MULTISPECTRAL LANDSAT IMAGES CLASSIFICATION USING A DATA CLUSTERING ALGORITHM
Multispectral Image Classification Networks Fuzzy Logic
font style='font-size:12px;'>
2015/7/29
This paper presents a new application of a data-clustering algorithm in Landsat image classification, which improves on
conventional classification methods. Neural networks have been widely used in ...
ion functions quantify super-resolution images and estimate apparent clustering due to over-counting
Correlation functions quantify super-resolution images estimate apparent clustering due to over-counting

We present an analytical method to quantify clustering in super-resolution localization images of static surfaces in two dimensions. The method also describes how over-counting of labeled molecules co...

Not long ago primary census data became available to publicity. It opened qualitatively new perspectives not only for researchers in demography and sociology, but also for those people, who somehow fa...
An invariant in shock clustering and Burgers turbulence
Shock clustering stochastic coalescence kinetic theory integrable systems Loitsiansky invariant
font style='font-size:12px;'>
2011/7/28
Abstract: 1-D scalar conservation laws with convex flux and Markov initial data are now known to yield a completely integrable Hamiltonian system. In this article, we rederive the analogue of Loitsian...

1-D scalar conservation laws with convex flux and Markov initial data are now known to yield a completely integrable Hamiltonian system. In this article, we rederive the analogue of Loitsiansky’s inva...
Resonance clustering in wave turbulent regimes: Integrable dynamics
Resonance clustering wave turbulent regimes Integrable dynamics
font style='font-size:12px;'>
2010/4/2
Two fundamental facts of the modern wave turbulence theory are 1) existence of power energy spectra in $k$-space, and 2) existence of "gaps" in this spectra corresponding to the resonance clustering. ...

2010/4/8
We have predicted theoretically and detected in laboratory experiments a new type of particle clustering (tangling clustering of inertial particles) in a stably stratified turbulence with imposed mean...

2010/10/19
In this work we use molecular dynamics simulation to study the clustering of dust particles deposited on a liquid surface. Our results are compatible with the picture that one particle attracts anothe...
