Abstract: A vibro-impact system driven by an DC electric motor is analyzed. The vibro-impact system is consisting of a crank-slider mechanism and one oscillator attached to it. Oscillator can impact in a fixed wall. The impact model has been assumed as inelastic, causing the change of velocity in sign and intensity by the restitution factor. Mathematical model which describes this system is a coupled system of second order nonlinear differential equations. The aim is to determine the influence of the stall torque on the motion of the oscillator. The system of differential equations is solved numerically. The results of the analysis are summarized in diagrams which are showing the relationship between the stall torque and the maximum amplitude of the oscillator movement, and the average value of excitation frequency of the electric motor. Frequency response diagram is also formed. Based on the diagrams regions of impact and non-impact solutions are distinguished, and regions with multiple solutio

Abstract: Introduction: The purpose of this study is to provide insights into emerging deployment of digital technology practices and sharing economy platform in the hospitality and tourism industry. As the digital technology displaces the traditional customer services and experience economy employee's work, it is imperative for those affected to understand the opportunities and threats of digital technology innovation on hospitality and tourism industry. Methods: Content analysis was utilized on relevant extant literature related to digital technology, disruptive digital innovation, robotics and artificial intelligence, sharing economy, collaborative economy, gig economy, platforms economy and fourth industrial revolution (IR 4.0) or industry 4.0. We identified 437-keyword counts, similar keywords were classified, combined and analysed. Results: Findings indicate digital technology praxis and sharing economy provide several opportunities in the management and advancing customer’s experience i
