Rule‐based preprocessing for data stream mining using complex event processing
Expert Systems, Volume 38, Issue 8, December 2021., 2021 Abstract Data preprocessing is known to be essential to produce accurate data from which mining methods are able to extract valuable knowledge. When data constantly arrives from one or more sources, preprocessing techniques need to be adapted to efficiently handle these data streams.

Existence of periodic positive solutions to nonlinear Lotka-Volterra competition systems [PDF]
Opuscula Mathematica, 2020 We investigate the existence of positive periodic solutions of a nonlinear Lotka-Volterra competition system with deviating arguments. The main tool we use to obtain our result is the Krasnoselskii fixed point theorem.
