Correlations Between Transportation and the Covid-19 Pandemic
(AIP Conference Proceedings, 2022) Barberi, Salvatore; Arena, Fabio; Termine, Francesco; Canale, Antonino; Olayode, Isaac Oyeyemi; Neduzha, Larysa; Zuccalà, Yuri
ENG: COVID pandemic has abruptly changed people habits and lifestyles worldwide, including the usage and perception towards all the different transportation systems; to this date (mid-2021), the pandemic has been going on for over a year now, and there is still no certainty about when it will end. A drastic decline in the number of commercial flights both national and international has happened, as a consequence of the lockdown policies adopted by the various countries around the globe in order to prevent the infection from spreading around, and with variable trends depending on the period and the reciprocal agreements between the various states. Land-side public transportation too has witnessed a backlash mainly due to similar policies or even not leaving home during lockdowns, often working remotely from home, and switching from public transportation to driving, walking or cycling if necessary. COVID-19 and transport are linked by a two-way relationship: if it is true that COVID-19 impacts on transport systems, it is also true that transport systems, in turn, have a very important role in the spread of the pandemic. Swabs first and vaccines recently, are raising new hopes about the pandemic ending soon. The consequences of COVID-19 will in any case be significant, and will revolutionize the way of conceiving transport, meaning new challenges for scientific research.
Dynamic Sustainable Processes Simulation to Study Transport Object Efficiency
(MDPI, Basel, Switzerland, 2022) Bondarenko, Iryna; Severino, Alessandro; Olayode, Isaac Oyeyemi; Campisi, Tiziana; Neduzha, Larysa
ENG: The development of reliability theory has led to the setting of tasks requiring consideration of the efficiency and functional safety of technical objects of transport over the life cycle. The paper demonstrates the possibility of using the universal laws of elastic wave theory to describe natural phenomena occurring in complex dynamic systems, on the examples of solving issues arising in the interaction of rolling stock and the railway track. The accounting of the time component and the ability of elastic waves to propagate energy in time and space allowed considering any interaction process as a chain of processes, incidence-reflection-refraction of force impulses of interaction. Understanding the physics of dynamic processes that occur in objects while performing their intended functions allows developers to improve objects in such a way as to minimize their life cycle cost and maximize their ability to perform their intended functions under different operating conditions. In addition, it allows the expansion of existing methods and approaches to diagnostics of dynamic transport systems. All this is a base for making it possible to develop an innovative and effective tool for engineers and scientists to assess the impact of technosphere transport objects on human habitats.
