Social Media Comment Management using SMOTE and Random Forest Algorithms
International Journal of Networked and Distributed Computing (IJNDC), 2018 Comment posting is one of the main features found in social media. Comment responses enrich the social network function especially for how-to content. In this work, we focus on cooking video clips which are popular among users. Various questions found in

Replica field theory for a polymer in random media
, 1999 In this paper we revisit the problem of a (non self-avoiding) polymer chain in a random medium which was previously investigated by Edwards and Muthukumar (EM).

Random walks in random media [PDF]
, 1992 In this thesis we study three RWIRE models. A RWIRE is simply a random walk where the transition rates are themselves random variables. The first model studied is a unit jump non directed RWIRE in discrete and continuous time. Results are presented for the "speed" of the RWIRE in discrete time.

The Unusual Universality of Branching Interfaces in Random Media
, 1994 We study the criticality of a Potts interface by introducing a {\it froth} model which, unlike its SOS Ising counterpart, incorporates bubbles of different phases. The interface is fractal at the phase transition of a pure system.

Evaluation of memory-preserving models for particle transport in random media [PDF]
EPJ Web of ConferencesA shortcoming of the Levermore-Pomraning (LP) model is its inaccuracy to treat the transport of particles in a diffusive material alternating with a transparent one. Enhanced-memory LP models have been proposed by Zimermann et al.

SPATIALLY SELECTIVE SPECKLE-CORRELOMETRY OF RANDOM INHOMOGENEOUS MEDIA: SIMULATION RESULTS [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2014 The paper deals with the results of Monte Carlo simulation of light propagation in a media with complex structure and dynamics by an original speckle-correlometry approach based on ring-like apertures and localized source of probe light.

A SIRS Epidemic Model Incorporating Media Coverage with Random Perturbation
Abstract and Applied Analysis, 2013 We investigate the complex dynamics of a SIRS epidemic model incorporating media coverage with random perturbation. We first deal with the boundedness and the stability of the disease—free and endemic equilibria of the deterministic model.

Numerical Simulation of Intensity Fluctuations in Random Laser Systems [PDF]
Журнал нано- та електронної фізики, 2012 The spectral behavior of a random lasing system (TiO2 powder dispersed in Rhodamine 6 G dye solution) is calculated using numerical calculations. The total integrated intensity is calculated for different incident optical intensities, particle densities,
