This paper presents a mathematical model of elastic vibrations arising from shock interaction in a four-body system.The resulting model has two applications: the study of linear elastic interaction and the study of nonlinear elastic interaction.The linear elastic body model is presented in analytical form.In the transition to nonlinear interaction,
The development and competition of the business world in the current era of globalization is getting higher.This study aims to determine the marketing strategies of basic food traders in the new market of Paiton.The method used is qualitative based on observation, interviews, and documentation.The results of the study showed that the marketing stra
The energy sector is currently undergoing a rapid transformation with the integration of power electronic converter (PEC)-interfaced renewable energy sources (RES), such as wind and solar photovoltaic (PV) systems, at both the transmission and distribution networks.Power system stability has been significantly influenced by this power grid transfor
