Studies of the Fractional Selkov Dynamical System for Describing the Self-Oscillatory Regime of Microseisms

open access: yesMathematics, 2022
A non-linear fractional Selkov dynamic system for mathematical modeling of microseismic phenomena is proposed. This system is a generalization of the previously known Selkov system, which has self-oscillatory modes and is used in biology to describe ...

Spatiotemporal Evolution of Land Subsidence in the Beijing Plain 2003–2015 Using Persistent Scatterer Interferometry (PSI) with Multi-Source SAR Data

open access: yesRemote Sensing, 2018
Land subsidence is one of the most important geological hazards in Beijing, China, and its scope and magnitude have been growing rapidly over the past few decades, mainly due to long-term groundwater withdrawal.

INNOVATION PROCESS MODELLING [PDF]

open access: yesAnnals of the University of Petrosani: Economics, 2011
Modelling phenomena in accordance with the structural approach enables one to simplify the observed relations and to present the classification grounds. An example may be a model of organisational structure identifying the logical relations between particular units and presenting the division of authority, work.

Mechanics of beams made from chiral metamaterials: Tuning deflections through normal-shear strain couplings

open access: yesMaterials & Design, 2020
In the current work, we demonstrate the potential of structures made of chiral artificial materials to balance bending loads through tensile loads, exploiting their inner normal to shear strain coupling.

A visual analysis of the process of process modeling [PDF]

open access: yesInformation Systems and E-Business Management, 2014
The construction of business process models has become an important requisite in the analysis and optimization of processes. The success of the analysis and optimization efforts heavily depends on the quality of the models.
